Phase II Trial of Concurrent Nivolumab and Radiation Therapy for Muscle-Invasive Bladder Cancer of Older or Chemotherapy-Ineligible Patients

PURPOSE

Bladder cancer is predominantly a disease of older individuals. Concurrent chemotherapy and radiation is a bladder-sparing strategy for management of muscle-invasive bladder cancer; however, many patients are not candidates for chemotherapy due to comorbidities or impaired performance status. We conducted a study in a chemotherapy-ineligible patient population with the objectives of evaluating the safety, efficacy, and quality-of-life effect of the combination of nivolumab and radiation therapy in patients with localized/locally advanced urothelial cancer.

METHODS AND MATERIALS

Eligible patients had muscle-invasive bladder cancer and were not candidates for standard chemoradiation strategy due to at least one of the following: performance status of 2, creatinine clearance ≤60 mL/min, cardiac disease, neuropathy, and intolerance to previous treatment. Creatinine clearance ≥40 mL/min, normal marrow, and liver function were required. The primary endpoint was progression-free survival at 12 months. Nivolumab was started within 3 days of radiation therapy and administered at a dose of 240 mg intravenously every 2 weeks for a maximum of 6 months. Radiation therapy was per standard of care for bladder cancer. Imaging and cystoscopy and biopsy evaluation were required at months 3, 6, and 12 and then annually until progression.

RESULTS

Twenty patients were enrolled, with a median age of 78.5 years (range, 58-95 years); 80% of patients were >70 years of age, and 8 (40%) were >80 years of age. Median creatinine clearance was 52 mL/min. Nine patients (48%) were progression free at 12 months. Median progression-free survival was 11.4 months (90% CI, 7.5-23.7 months), and median overall survival was 15.6 months (90% CI, 9.1-26.1 months).

CONCLUSIONS

Concurrent nivolumab and radiation therapy is tolerable but demonstrated limited efficacy in an older population with multiple comorbidities. Immune correlates demonstrated that patients with baseline programmed cell death ligand 1 combined prognostic score ≥5% had numerically longer progression-free survival.

Smaller Hippocampal Volume Is Associated With Reduced Posttraumatic Stress Symptoms in Children With Cancer and Survivors Following a Brief Novel Martial Arts-Based Intervention

PURPOSE

Children with cancer and survivors frequently report posttraumatic stress symptoms (PTSS), which are associated with volumetric changes in stress-sensitive brain regions, including the hippocampus.

METHODS

We examined the impact of a novel, 4-week martial-arts-based meditative intervention on cancer-related PTSS in 18 pediatric patients and survivors and whether baseline hippocampal volumes correlate with PTSS severity and/or PTSS changes over time.

RESULTS

Overall, PTSS did not significantly change from baseline to post-intervention. Smaller hippocampal volume was correlated with more severe re-experiencing PTSS at baseline, and greater reductions in PTSS post-intervention.

CONCLUSIONS

Together, hippocampal volume may be a biomarker of PTSS severity and intervention response. Identifying hippocampal volume as a potential biomarker for PTSS severity and intervention response may allow for more informed psychosocial treatments.

Evaluation of health behaviors and overall quality of life in younger adult African American cancer survivors

BACKGROUND

Epidemiological studies of cancer survivors have predominantly focused on non-Hispanic White, elderly patients, despite the observation that African Americans have higher rates of mortality. Therefore, we characterized cancer survivorship in younger African American survivors using the Detroit Research on Cancer Survivors (ROCS) study to assess health behaviors and quality of life.

METHODS

Five hundred and seventeen patients diagnosed with any cancer between the ages of 20-49 (mean age: 42 years; SD: 6.7 years) completed a survey to identify important clinical, behavioral, and sociodemographic characteristics, measures of health literacy, and experiences of discrimination. Quality of life outcomes were evaluated in patients using FACT-G, FACT-Cog, and PROMIS® Anxiety and Depression scales. Stepwise linear and logistic regression were used to assess the association between quality of life measures and participant characteristics.

RESULTS

The mean FACT-G score was 74.1 (SD: 21.3), while the FACT-Cog was 55.1 (SD: 17.1) (FACT-G range 0-108 with higher scores indicating better function; elderly cancer patient mean: 82.2; FACT-Cog 18-item range 0-72 points with higher scores indicating better perceived cognitive functioning; scores <54 indicating cognitive impairment). In addition, 27.1% and 21.6% of patients had a score indicative of moderate or severe anxiety and depression, respectively. Perceived discrimination and the number of discriminatory events were significantly associated with reductions in three of the four quality of life measures. Health literacy was positively associated with all four health measures, while total comorbidity count was negatively associated with three of the four measures.

CONCLUSION

Younger adult African American cancer survivors who report experiencing discrimination and suffer from multiple comorbid conditions have poorer mental and overall health. Understanding the unique clinical and socioeconomic stressors that influence this patient population is essential for reducing health disparities and improving long-term survivorship.

The impact of the COVID-19 pandemic on African American cancer survivors

BACKGROUND

Coronavirus disease 2019 (COVID-19) has had profound effects on population health to date. African American cancer survivors are particularly vulnerable to developing severe consequences; therefore, understanding the impact of the virus on this patient population is critical.

METHODS

The Detroit Research on Cancer Survivors cohort is a unique effort to understand the determinants of poor outcomes in African American cancer survivors. To date, more than 4500 cancer survivors and nearly 950 primary caregivers have been enrolled; participation includes a survey and the collection of biospecimens, medical records, and tumor tissue. Beginning in the spring of 2020, a supplemental survey focusing on the impact of COVID-19 was offered to enrolled participants. The analysis included 890 survivors.

RESULTS

Nearly all survivors (>99%) reported changes in their daily activities in an effort to reduce the risk of infection. More than 40% of the survivors reported some disruption in their access to medical care. A substantial proportion of the survivors (>40%) reported feeling anxious, depressed, and/or isolated during the COVID-19 pandemic. Approximately 40% of the patients reported changes in health behaviors shown to negatively affect survivorship outcomes (physical inactivity, smoking, and alcohol use) as a result of the pandemic.

CONCLUSIONS

The influence of the COVID-19 pandemic on African American cancer survivors is substantial: it has affected both their physical and mental health. Coupled with changes in health behaviors, these factors will likely affect outcomes in this high-risk patient population, and this makes further study and interventions necessary to mitigate the long-term impact of the pandemic on cancer outcomes.

Parent post-traumatic growth after a child's critical illness

OBJECTIVE

Post-traumatic growth is the experience of a positive change after a traumatic event. Our objective is to characterize the factors associated with post-traumatic growth in parents after a child's pediatric intensive care unit (PICU) admission.

STUDY DESIGN

A cross-sectional survey study examining post-traumatic growth and select independent variables in parents 1 year after a child's ≥72 h PICU admission for an acute illness or injury. The study was completed in parents of children discharge alive from a tertiary care PICU from January 1, 2017 to December 31, 2017. A mixed-effects linear regression model was built to evaluate the association of post-traumatic stress, anxiety, depression, resiliency, family function, and child function with post-traumatic growth.

RESULTS

Eighty-two parents of 52 children discharged alive in 2017 completed the survey. Fifty-two percent were ≥35 years and 64.3% were mothers. Median age of their children was 2.8 years (IQR 0.5-11.3) with a median hospital stay of 12 Days (IQR 6-20). Moderate-to-high levels of post-traumatic growth occurred in 67.1% of parents. Increased hospital length of stay (β Coeff 0.85; p = 0.004, 95% CI 0.27, 1.43) and parent post-traumatic stress symptoms (β Coeff 1.04; p = 0.006, 95% CI 0.29, 1.78) were associated with increased post-traumatic growth, and increased parent depression symptoms (β Coeff -1.96; p = 0.015; 95% CI -3.54, -0.38) with decreased post-traumatic growth.

CONCLUSION

Longer child hospital stays and increased parent post-traumatic stress symptoms were associated with increased post-traumatic growth, while increased depression was associated with less post-traumatic growth. The impact of future PICU parent psychosocial interventions on parents may be best assessed using a dual outcome focused on both reducing negative mental health symptoms while concurrently promoting skills to facilitate parent adaptation and post-traumatic growth.

Chemotherapy-induced peripheral neuropathy in African American cancer survivors: Risk factors and quality of life outcomes

Background

Epidemiological studies of chemotherapy‐induced peripheral neuropathy (CIPN) have predominantly focused on non‐Hispanic White patients, despite the observation that African Americans are more likely to experience CIPN. To address this health disparities gap, we sought to identify non‐genetic risk factors and comorbidities associated with CIPN in African American cancer survivors using the Detroit Research on Cancer Survivors study.

Methods

Logistic regression was used to evaluate relationships between presence of self‐reported CIPN and relevant clinical characteristics in 1045 chemotherapy‐treated African American cancer survivors. Linear regression was used to evaluate risk factors for CIPN and quality of life outcomes that reflect physical, social, emotional, and functional domains of health.

Results

Patients with CIPN were more likely to report hypertension (OR = 1.28, 95% CI: 0.98–1.67, p = 0.07), hypercholesterolemia (OR = 1.32, 95% CI: 1.001–1.73, p = 0.05), history of depression (OR = 1.62, 95% CI: 1.18–2.25, p = 0.003), and diabetes (OR = 1.33, 95% CI: 0.98–1.82, p = 0.06) after adjustment for age at diagnosis, sex, and cancer site. BMI (OR = 1.02 kg/m², 95% CI: 1.006–1.04 kg/m², p = 0.008) was also positively associated with CIPN. In addition, CIPN status was significantly associated with quality of life (FACT‐G total: β = −8.60, 95% CI: −10.88, −6.32) p < 0.0001) and mood (PROMIS^® Anxiety: β = 4.18, 95% CI: 2.92–5.45, p < 0.0001; PROMIS^® Depression: β = 2.69, 95% CI: 1.53–3.84, p < 0.0001) after adjustment for age at diagnosis, sex, cancer site, and comorbidities. Neither alcohol consumption (OR = 0.88, 95% CI: 0.68–1.14, p = 0.32) nor tobacco use (ever smoked: OR = 1.04, 95% CI: 0.80–1.35, p = 0.76; currently smoke: OR = 1.28, 95% CI: 0.90–1.82, p = 0.18) was associated with increased CIPN risk.

Conclusion

Risk factor profiles in African Americans are not entirely consistent with those previously reported for non‐Hispanic White patients. Neglecting to understand the correlates of common chemotherapy‐induced toxicities for this patient population may further contribute to the health disparities these individuals face in receiving adequate healthcare.

A Review of Research on Disparities in the Care of Black and White Patients With Cancer in Detroit

Racial disparities in cancer incidence and outcomes are well-documented in the US, with Black people having higher incidence rates and worse outcomes than White people. In this review, we present a summary of almost 30 years of research conducted by investigators at the Karmanos Cancer Institute's (KCI's) Population Studies and Disparities Research (PSDR) Program focusing on Black-White disparities in cancer incidence, care, and outcomes. The studies in the review focus on individuals diagnosed with cancer from the Detroit Metropolitan area, but also includes individuals included in national databases. Using an organizational framework of three generations of studies on racial disparities, this review describes racial disparities by primary cancer site, disparities associated with the presence or absence of comorbid medical conditions, disparities in treatment, and disparities in physician-patient communication, all of which contribute to poorer outcomes for Black cancer patients. While socio-demographic and clinical differences account for some of the noted disparities, further work is needed to unravel the influence of systemic effects of racism against Black people, which is argued to be the major contributor to disparate outcomes between Black and White patients with cancer. This review highlights evidence-based strategies that have the potential to help mitigate disparities, improve care for vulnerable populations, and build an equitable healthcare system. Lessons learned can also inform a more equitable response to other health conditions and crises.

The impact of the COVID-19 pandemic on African American cancer survivors living in metropolitan Detroit

12129

Background: COVID-19 has had profound direct and indirect effects on population health to date and long-term effects are anticipated. Vulnerabilities to the most serious consequences of infection include older age, obesity, African American race and the presence of comorbid conditions. African American cancer survivors represent a particularly high-risk group, therefore understanding the impact of the virus and our strategies to prevent its spread on this patient population is important. Methods: The Detroit Research on Cancer Survivors (ROCS) cohort is a unique effort to understand the determinants of poor outcomes in African American cancer survivors. Eligible participants were diagnosed with breast, prostate, colorectal, or lung cancer on or after 1/1/2013, or with endometrial or any other cancer before age 50 on or after 01/01/2016 and were identified through the Metropolitan Detroit Cancer Surveillance System cancer registry. To date, we have enrolled 4173 survivors. Full participation includes completion of a baseline survey, and collection of biospecimens, medical records and tumor tissue, if available. Participants are also followed annually for outcomes and changes in history. A supplemental survey focused on the impact of COVID-19 was offered to enrolled participants beginning in the spring of 2020. The results presented here include data from 890 survivors who also completed the ROCS COVID survey. Results: Nearly all ( > 99%) survivors reported some change in their daily activities in an effort to reduce the risk of infection. At the time of survey, just over 1/3 of participants reported being tested for the virus and among those, 12% reported positive results. More than 40% of survivors reported some disruption in their access to medical care. A substantial ( > 40%) proportion of survivors reported feeling anxious, depressed and/or isolated during the COVID-19 pandemic. Approximately 40% of patients reported changes in health behaviors as a direct result of the pandemic that are known to negatively affect survivorship outcomes (physical inactivity, smoking, alcohol use). Notably, 30% of survivors reported declines in physical activity and these declines were significantly associated with increased anxiety (p = 0.008), depression (p = 0.005) and poorer health-related quality of life (p < 0.001). Conclusions: The influence of the COVID-19 pandemic on African American cancer survivors has been substantial, affecting both their physical and mental health and access to needed medical care. Coupled with changes in health behaviors as a direct result of the pandemic, these factors will likely affect outcomes in this high-risk patient population making further study and interventions necessary to mitigate the long-term impact of the pandemic on cancer outcomes.

Factors Associated With Racial/Ethnic Group-Based Medical Mistrust and Perspectives on COVID-19 Vaccine Trial Participation and Vaccine Uptake in the US

IMPORTANCE

The impact of COVID-19 in the US has been far-reaching and devastating, especially in Black populations. Vaccination is a critical part of controlling community spread, but vaccine acceptance has varied, with some research reporting that Black individuals in the US are less willing to be vaccinated than other racial/ethnic groups. Medical mistrust informed by experiences of racism may be associated with this lower willingness.

OBJECTIVE

To examine the association between race/ethnicity and rejection of COVID-19 vaccine trial participation and vaccine uptake and to investigate whether racial/ethnic group-based medical mistrust is a potential mediator of this association.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional survey study was conducted from June to December 2020 using a convenience sample of 1835 adults aged 18 years or older residing in Michigan. Participants were recruited through community-based organizations and hospital-academic networks.

MAIN OUTCOMES AND MEASURES

Separate items assessed whether respondents, if asked, would agree to participate in a research study to test a COVID-19 vaccine or to receive a COVID-19 vaccine. Participants also completed the suspicion subscale of the Group-Based Medical Mistrust Scale.

RESULTS

Of the 1835 participants, 1455 (79%) were women, 361 (20%) men, and 19 (1%) other gender. The mean (SD) age was 49.4 (17.9) years, and 394 participants (21%) identified as Black individuals. Overall, 1376 participants (75%) reported low willingness to participate in vaccine trials, and 945 (52%) reported low willingness to be vaccinated. Black participants reported the highest medical mistrust scores (mean [SD], 2.35 [0.96]) compared with other racial/ethnic groups (mean [SD] for the total sample, 1.83 [0.91]). Analysis of path models revealed significantly greater vaccine trial and vaccine uptake rejection among Black participants (vaccine trial: B [SE], 0.51 [0.08]; vaccine uptake: B [SE], 0.51 [0.08]; both P < .001) compared with the overall mean rejection. The association was partially mediated by medical mistrust among Black participants (vaccine trial: B [SE], 0.04 [0.01]; P = .003; vaccine uptake: B [SE], 0.07 [0.02]; P < .001) and White participants (vaccine trial: B [SE], -0.06 [0.02]; P = .001; vaccine uptake: B [SE], -0.10 [0.02]; P < .001).

CONCLUSIONS AND RELEVANCE

In this survey study of US adults, racial/ethnic group-based medical mistrust partially mediated the association between individuals identifying as Black and low rates of acceptance of COVID-19 vaccine trial participation and actual vaccination. The findings suggest that partnerships between health care and other sectors to build trust and promote vaccination may benefit from socially and culturally responsive strategies that acknowledge and address racial/ethnic health care disparities and historical and contemporary experiences of racism.

Financial and Employment Impacts of Cancer and COVID-19 Among African American Cancer Survivors

Purpose: Financial hardship due to cancer is more common among African American than White survivors. The COVID-19 pandemic and its economic fallout have also disproportionately affected African Americans. The purpose of this study is to describe the financial and employment impacts of COVID-19 in a population of African American cancer survivors and to compare those impacts with those experienced after a cancer diagnosis. Methods: Results include survey data from 593 participants in the population-based Detroit Research on Cancer Survivors (ROCS) cohort who completed the ROCS enrollment survey and a supplemental questionnaire related to the impact of the COVID-19 pandemic on their financial wellbeing and employment. Most participants (96%) were not diagnosed with COVID-19 by the time they completed the supplement and reflect the societal impact of the pandemic rather than a personal COVID-19 diagnosis. Analyses compare reports of financial hardship (using assets, borrowing money, experiencing debt, decreases in income) and employment impacts (changes to work schedules, duties, hours, employment status) due to cancer and due to the COVID-19 pandemic. Results: A similar proportion of ROCS participants reported financial hardship (41% vs. 42%) and borrowing money (5% vs. 6%) related to the COVID pandemic and their cancer diagnosis, respectively. Fewer survivors reported borrowing money (9% vs. 17%; p&lt;0.001) or experiencing a decrease in income due to COVID than cancer (20% vs. 28%; p = 0.001); however; more reported debt associated with COVID (30% vs. 17%; p&lt;0.001). Changes to work schedules (44% vs. 36%) and hours worked (44% vs. 28%) related to the COVID pandemic and cancer were common, and not statistically different from one another. More survivors changed their work duties due to the COVID pandemic (20%) than cancer (12%; p = 0.048). Prevalence of changes to employment status were similar for cancer (6%) and COVID (11%). Conclusions: The COVID-19 pandemic was associated with similar levels of overall financial hardship, and higher prevalence of debt and some work changes, than individual cancer experiences. These additional burdens on a financially vulnerable population could exacerbate existing cancer-related inequities.

Impact of Patients' Companions on Clinical Encounters Between Black Patients and Their Non-Black Oncologists

PURPOSE

The presence of caregivers or companions during clinical encounters influences the dynamics and outcomes of the encounters. Most prior studies of companions in clinical encounters focus on non-Hispanic White patients. However, there is generally lower-quality patient-physician communication during encounters with Black patients; these communication differences may contribute to racial health disparities. The purpose of the present study was to examine effects of the presence and active participation of companions on encounters between Black patients with cancer and non-Black oncologists.

METHODS

This was a secondary analysis of data collected during a larger intervention study. Participants were Black patients with breast, colon, or lung cancer who had a treatment-discussion encounter with a participating non-Black medical oncologist. Video recordings of encounters were coded for patient, companion, and oncologist communication. After the encounter, patients reported perceptions of the recommended treatment; patients and oncologists reported perceptions of each other.

RESULTS

Data from 114 patients and 19 oncologists were included in analyses. Only 47% of patients brought a companion to the encounter. Oncologists spent more time with accompanied Black patients, used more patient-centered communication with them, and perceived them as having more social support compared with unaccompanied Black patients. Oncologists reported that accompanied patients asked more questions. When companions participated more actively in the encounter, oncologists used more patient-centered communication.

DISCUSSION

Bringing a companion to oncology appointments may be beneficial to Black patients because oncologists spend more time with patients, use more patient-centered communication, and perceive patients more positively, all of which may ultimately improve patient health and well-being outcomes.

Martial Arts-Based Therapy Reduces Pain and Distress Among Children with Chronic Health Conditions and Their Siblings

Objective

Test whether a martial arts-based therapy, Kids Kicking Cancer (KKC), can reduce pain and emotional distress in children with cancer, other chronic health conditions (e.g., sickle cell), and healthy siblings.

Methods

This study surveyed children’s pain and distress levels immediately before and after a 1-hr in-person KKC class. Eligible participants were enrolled in standard KKC classes, were diagnosed with a chronic health condition (e.g., cancer, sickle cell) or were the sibling of a child diagnosed and were between the ages of 5–17 years (inclusive). Children reported on their pain and distress using Likert-style scales (Coloured Analog Scale and modified FACES scale, respectively). Friedman test was used to test for overall changes in pain and distress, and within subgroups. Age and sex effects were evaluated using Spearman’s rank-order correlation. Additional Yes/No questions were administered regarding KKC satisfaction and use of techniques.

Results

Fifty-nine youth (19 cancer patients, 17 non-cancer patients, 23 siblings; 5–17 yrs, 26 females) completed this study. Overall, there was a significant reduction in pain (p = 0.033) and emotional distress (p < 0.001) after a 1-hr class, with 50% and 89% of youth reporting a reduction in pain and distress, respectively. On average, pain levels remained within the mild/moderate range on average (i.e., pre vs. post levels; pre: M = 1.67, post: M = 1.33) and emotional distress went from mild/moderate to none/mild distress, on average (pre: M = 1.92, post: M = 1.08). Youth with higher pre-class pain and distress reported greater reductions (p = 0.001 and p < 0.001, respectively). The reduction in pain appeared to be most pronounced with cancer and non-cancer patients. In contrast, the reduction in distress appeared to be most pronounced among healthy siblings. However, overall, reductions in pain and distress did not significantly differ among subgroups (i.e., cancer patients, non-cancer patients, siblings), and change in pain and distress was not associated with age or sex. Ninety-six percent of youth would recommend KKC to others and 81% reported using KKC techniques (e.g., the Breath Brake^TM or other martial arts techniques) outside of class, such as at home.

Conclusion

Results support the more widespread application of KKC as a psychosocial intervention for reducing pain and distress in various pediatric populations.

Examining the dynamic nature of nonverbal communication between Black patients with cancer and their oncologists

BACKGROUND

Although communication quality is associated with patient outcomes, racial disparities in communication exist, disproportionately burdening Black patients. However, most communication research focuses on verbal behaviors in predominantly White patient populations. We used a newly developed and theory-guided network analysis that examines the dynamic interplay and behavioral convergence and divergence between Black patients with cancer and their oncologists during cancer treatment discussions.

METHODS

We applied a nonverbal behavioral coding system to thin slices of video recordings of Black patients and their oncologists discussing treatment. We then estimated 3 networks: 1) a temporal network to determine whether a nonverbal behavior predicts another nonverbal behavior at the next time point in an interaction, and how much each nonverbal behavior influences other nonverbal behaviors and is influenced by other nonverbal behaviors; 2) a contemporaneous network to determine whether a nonverbal behavior co-occurs with other nonverbal behaviors at the same time point in an interaction; and 3) a between-dyads network to examine the covariation between nonverbal behaviors across all dyads.

RESULTS

Black patients (n = 74) and their non-Black physicians (n = 15) showed a mix of convergence and divergence in their nonverbal behaviors at the same points in time, from one time point to the next, and across dyads. Across analyses, convergence was most likely to occur when physicians matched their behaviors to their patients; especially with smiling, gaze, leaning, and laughter behaviors.

CONCLUSION

Our findings reveal patterns of modifiable behaviors that can potentially inform interventions to reduce disparities in clinical communication and, in turn, treatment and mortality disparities.

The impact of high intensity interval training on functional performance, body composition and quality of life in a diverse group of cancer survivors

12057

Background: Given the well-documented benefits of regular exercise to cancer survivors, in 2012, an expert panel assembled by the American Cancer Society recommended that patients engage in at least 150 minutes per week of moderate-to-vigorous physical activity. However, few patients meet this goal. We have also observed racial differences in reported participation in regular exercise among cancer survivors living in Metropolitan Detroit, Michigan. Methods: The CAPABLE study is a 12- week pilot exercise intervention that introduces cancer survivors to the sport of CrossFit. We evaluated the impact of this unique, high-intensity interval training method on functional performance, cardiovascular endurance, body composition and health-related quality of life (HRQOL) as measured by the Functional Assessment of Cancer Therapy (FACT) instrument. All measures were summarized at baseline and program exit. Paired signed rank tests were used to assess change in each of these measures over time. Results: Of the 48 participants enrolled in the pilot, 37 (77%) were considered adherent to the program (attending at least 75% of sessions over the 12-week period). The mean age of participants was 58.5 years, 73% identified as African American and the majority of participants were breast cancer survivors (N = 20). The mean body mass index (BMI) at baseline was 32.8 kg/m2 decreasing to a mean of 31.7 kg/m2 at exit (BMI change -1.1, p < 0.001). Similar changes were observed in % body fat measured by bioelectrical impedance. There were significant improvements in all measures of functional performance over 12-weeks (all p < 0.001). We observed significant and meaningful improvements in reported HRQOL measured by the FACT survey, overall (FACTG total change +9.5 (p < 0.001)) and in each one of the individual domains (physical, social, emotional, and functional well-being). Conclusions: We observed significant improvements in performance, body composition and quality of life among cancer survivors introduced to a high-intensity interval training program. Understanding and eliminating barriers to programs like these are critical to improving outcomes and reducing cancer health disparities. Clinical trial information: NCT03750981 .

Physical activity and quality of life in African American cancer survivors: The Detroit Research on Cancer Survivors study

BACKGROUND

The benefit of regular exercise in improving cancer outcomes is well established. The American Cancer Society (ACS) released a recommendation that cancer survivors should engage in at least 150 minutes of moderate to vigorous physical activity (PA) per week; however, few report meeting this recommendation. This study examined the patterns and correlates of meeting ACS PA recommendations in the Detroit Research on Cancer Survivors (ROCS) cohort of African American cancer survivors.

METHODS

Detroit ROCS participants completed baseline and yearly follow-up surveys to update their health and health behaviors, including PA. This study examined participation in PA by select characteristics and reported health-related quality of life (HRQOL) as measured with the Functional Assessment of Cancer Therapy and Patient-Reported Outcomes Measurement Information System instruments.

RESULTS

Among the first 1500 ROCS participants, 60% reported participating in regular PA, with 24% reporting ≥150 min/wk. Although there were no differences by sex, prostate cancer survivors were the most likely to report participating in regular PA, whereas lung cancer survivors were the least likely (P = .022). Survivors who reported participating in regular PA reported higher HRQOL (P < .001) and lower depression (P = .040).

CONCLUSIONS

Just 24% of African American cancer survivors reported meeting the ACS guidelines for PA at the baseline, but it was encouraging to see increases in activity over time. Because of the established benefits of regular exercise observed in this study and others, identifying and reducing barriers to regular PA among African American cancer survivors are critical for improving outcomes and minimizing disparities.

Preferences for notification of imaging results in patients with metastatic cancer

OBJECTIVE

This study examines the preferences of patients with metastatic cancer regarding notification of imaging results, as well as distress surrounding the process.

METHODS

On imaging day, preferences for notification, expectations of results, health literacy, and social support were measured. After receiving results, patients reported on actual delivery methods. At both times, patients were screened for overall distress, anxiety, and depression.

RESULTS

The majority of patients preferred notification within 2 days and during a face-to-face visit with their oncologist. Although levels of distress, anxiety, and depression were low, patients with higher anxiety, depression, and social isolation had higher distress. There was no correlation between absolute distress levels and agreement between notification preferences and actual delivery methods. Receiving results from a preferred provider was associated with a decrease in distress from imaging day to follow-up. Face-to-face delivery of results was more important to people with lower health literacy.

CONCLUSIONS

While distress regarding the receipt of results was low, it was higher for some groups of patients. Attending to the preferences of these subgroups may help to minimize distress.

PRACTICE IMPLICATIONS

Receiving results from preferred personnel and diminishing patients' sense of social isolation might provide psychological benefit during the period surrounding imaging.

Understanding differences in the long-term psychosocial adjustment of pediatric cancer patients and their parents: an individual differences resources model

The experience of childhood cancer is a major life stressor for children and their parents. There is substantial variability among pediatric cancer patients and their parents in their ability to cope with the cancer. Although other models typically focus on the psychological resources families use to broadly cope with a diagnosis of pediatric cancer, we present a model that focuses specifically how parents and children cope with the stress of invasive and often painful treatment episodes. Our resources model is further distinct with its focus on individual differences in personal (e.g., personality traits) and social (e.g., social support) resources and the role these differences may play in psychosocial adjustment of families confronting pediatric cancer. We use findings from the broader pediatric cancer research literature and our own 15-year program of research on individual differences in psychological resources and parents and children's responses to treatment episodes to provide empirical support for our model. Support was found for the six premises of the model: (a) parent resources influence their longer-term psychosocial adjustment, (b) parent resources influence children's responses to treatment episodes, (c) parent resources indirectly influence their longer-term psychosocial adjustment through their responses to treatment episodes, (d) children's personal resources influence how parent responses to treatment episodes, (e) children's resources influence their longer-term psychosocial adjustment, and (f) children's resources indirectly influence their longer-term psychosocial adjustment through their responses to treatment episodes. Understanding how the availability of resources influences parents and children confronting cancer provides a foundation for future research on individual differences in resources and offers other avenues through which clinicians can assess and treat families at risk for poor psychosocial adjustment during treatment and in their life beyond cancer treatments.

Employment outcomes, anxiety, and depression among caregivers of African American cancer survivors

175

Background: Cancer patients commonly rely on loved ones to act as informal caregivers during and after treatment. Caregivers may need to take time off work or make other employment changes to handle caregiving demands. Employment changes due to caregiving and their impacts on psychological outcomes are not well understood, especially among caregivers of African American cancer survivors. Methods: Results include information from caregivers of participants in the Detroit Research on Cancer Survivors (ROCS) cohort, a population-based study of African American survivors of breast, colorectal, lung, or prostate cancer from Metropolitan Detroit. ROCS participants nominated a friend or family member who acted as a caregiver to participate in the caregiver study. Caregivers provided information on employment and PROMIS depression and anxiety measures. The relationship between work outcomes and anxiety/depression was assessed using logistic regression models controlling for age, sex, income, and the caregiver’s relationship to the survivor. Results: For the first 350 caregivers enrolled, more than half (56%) were employed (42% full time, 14% part time) at the time of the survivor’s diagnosis. 53% of employed caregivers took time off work, including 40% who took unpaid time off to provide care. 16% took one month or more off work, including 12% who took at least one month of unpaid time. Taking at least one month off was associated with 2.3 (95% CI: 1.0, 5.4) times the odds of depressive symptoms but was not associated with anxiety. Extended unpaid time off was not associated with depression or anxiety. 38% of employed caregivers reported that it was somewhat, very or extremely difficult to balance work and caregiving. Difficulty balancing work and caregiving was associated with 3.1 times the odds of depressive symptoms (95% CI: 1.5, 6.2), and 2.2 times the odds of any anxiety (95% CI: 1.1, 4.3) compared with those who reported little or no difficulty. Conclusions: Difficulty balancing work and caregiving is common among caregivers of African American cancer survivors, and is associated with symptoms of depression and anxiety. Supports for caregivers facing employment challenges may improve their psychosocial wellbeing.

Employment Outcomes, Financial Burden, Anxiety, and Depression Among Caregivers of African American Cancer Survivors

PURPOSE

Caregivers of cancer survivors may need to take time off work or make other employment changes to handle caregiving demands. Work impacts of caregiving, financial burden, and psychosocial outcomes of caregivers are not well understood.

METHODS

Results include information from surveys completed by 202 employed caregivers of participants in the Detroit Research on Cancer Survivors cohort, a population-based cohort of African American survivors of breast, colorectal, lung, or prostate cancer. Relationships between work outcomes, financial burden, and anxiety and depression were assessed using logistic regression models controlling for demographic and cancer-related factors.

RESULTS

Most (73.8%) caregivers made some employment change. Sixty percent changed their schedule, hours, duties, or employment status; 15.3% took at least 1 month off to provide care, and 38% reported difficulty balancing work and caregiving. Employment changes were strongly associated with difficulty balancing work and caregiving (odds ratio [OR], 5.83; 95% CI, 2.38 to 14.0) and financial burden (OR, 2.12; 95% CI, 1.05 to 4.27). Difficulty balancing work and caregiving was associated with symptoms of anxiety (OR, 1.86; 95% CI, 1.01 to 3.43) and depression (OR, 2.40; 95% CI, 1.16 to 4.96). High (v low) financial burden was associated with symptoms of anxiety (OR, 2.85; 95% CI, 1.01 to 8.06).

CONCLUSION

Difficulty balancing work and caregiving is common among caregivers of African American cancer survivors and is associated with symptoms of depression and anxiety. Supports for caregivers facing employment challenges may improve their psychosocial well-being.

Financial Hardship and Quality of Life among African American and White Cancer Survivors: The Role of Limiting Care Due to Cost

BACKGROUND

Financial hardship is common among cancer survivors and is associated with both limiting care due to cost and with poor health-related quality of life (HRQOL). This study estimates the association between limiting care due to cost and HRQOL in a diverse population of cancer survivors and tests whether limiting care mediates the association between financial hardship and HRQOL.

METHODS

We used data from 988 participants (579 African American, 409 white) in the Detroit Research on Cancer Survivors (ROCS) pilot, a hospital-based cohort of breast, colorectal, lung, and prostate cancer survivors. We assessed associations between financial hardship, limiting care, and HRQOL [measured by the Functional Assessment of Cancer Therapy-General (FACT-G)] using linear regression and mediation analysis controlling for demographic, socioeconomic, and cancer-related variables.

RESULTS

FACT-G scores were 4.2 [95% confidence interval (CI), 2.0-6.4] points lower among survivors who reported financial hardship compared with those who did not in adjusted models. Limiting care due to cost was associated with a -7.8 (95% CI, -5.1 to -10.5) point difference in FACT-G scores. Limiting care due to cost explained 40.5% (95% CI, 25.5%-92.7%) of the association between financial hardship and HRQOL overall, and 50.5% (95% CI, 29.1%-188.1%) of the association for African American survivors.

CONCLUSIONS

Financial hardship and limiting care due to cost are both associated with lower HRQOL among diverse cancer survivors, and this association is partially explained by limiting care due to cost.

IMPACT

Actions to ensure patients with cancer can access appropriate care could lessen the impact of financial hardship on HRQOL.

The Detroit Research on Cancer Survivors (ROCS) Pilot Study: A Focus on Outcomes after Cancer in a Racially Diverse Patient Population

BACKGROUND

African Americans are often diagnosed with advanced stage cancer and experience higher mortality compared with whites in the United States. Contributing factors, like differences in access to medical care and the prevalence of comorbidities, do not entirely explain racial differences in outcomes.

METHODS

The Detroit Research on Cancer Survivors (ROCS) pilot study was conducted to investigate factors related to short- and long-term outcomes among patients with cancer. Participants completed web-based surveys, and mailed saliva specimens were collected for future genetic studies.

RESULTS

We recruited 1,000 participants with an overall response rate of 68%. Thirty-one percent completed the survey without any interviewer support and the remaining participated in an interviewer-administered survey. Seventy-four percent provided a saliva specimen and 64% consented for tumor tissue retrieval. African American survivors required more interviewer support (P < 0.001); however, their response rate (69.6%) was higher than non-Hispanic whites (65.4%). African Americans reported poorer overall cancer-related quality of life compared with non-Hispanic whites, measured by FACT-G score (P < 0.001), however, this relationship was reversed after controlling for socioeconomic factors, marital status, and the presence of comorbidities.

CONCLUSIONS

In this pilot study, we demonstrated that a web-based survey supplemented with telephone interviews and mailed saliva kits are cost-effective methods to collect patient-reported data and DNA for large studies of cancer survivors with a high proportion of minority patients. The preliminary data collected reinforces differences by race in factors affecting cancer outcomes. Our efforts continue as we expand this unique cohort to include more than 5,000 African American cancer survivors.

IMPACT

Formal investigation of factors influencing adverse outcomes among African American cancer survivors will be critical in closing the racial gap in morbidity and mortality.

The influence of affective behavior on impression formation in interactions between black cancer patients and their oncologists

OBJECTIVE

Black patients and their physicians tend to form relatively negative impressions of each other, and these may contribute to racial disparities in health outcomes. The current research tested the hypothesis that the interaction between positive and negative affective behavior predicts the most positive impressions in clinic visits between Black patients and their oncologists.

METHOD

Naïve coders rated patients' and oncologists' positive and negative affective behavior in thin slices from 74 video recorded clinic visits. We examined whether (a) physician positive affect, negative affect, or their interaction predicted patients' perceptions of patient-centeredness, trustworthiness, and confidence in recommended treatments and (b) patient positive affect, negative affect, or their interaction predicted physicians' perceptions of patient cognitive ability, likelihood of treatment adherence, and likelihood of treatment tolerance. We also tested whether affective behavior mediated relationships between race-related attitudes and post-visit impressions or influenced post-visit impressions independently of attitudes.

RESULTS

When oncologists displayed relatively high levels of both positive and negative affect, patients were more confident in recommended treatments but did not rate physicians higher in patient centeredness or trustworthiness. When patients expressed relatively high levels of positive and negative affect, oncologists perceived patients to be higher in cognitive ability and more likely to adhere to treatment recommendations, but no more likely to tolerate treatments. Affective behavior influenced impressions independently of race-related attitudes.

CONCLUSIONS

Positive and negative affective behaviors jointly contribute to impression formation in clinic visits between Black patients and oncologists, and may have implications for patient treatment and outcomes in this underserved patient population.

Longitudinal Analysis of Parent Communication Behaviors and Child Distress during Cancer Port Start Procedures

BACKGROUND

The roles parents play in supporting their child during painful cancer procedures have been studied as communication strategies versus a broader caring framework and from a cross-sectional versus longitudinal perspective.

OBJECTIVES

To examine the longitudinal change in parent communication behaviors over repeated cancer port start procedures experienced by their children.

METHODS

This study used a longitudinal design. Two trained raters coded 104 recorded videos of port starts from 43 children being treated for cancer. This included 25 children with two video-recorded port starts and 18 children with three (T1, T2, T3). The Parent Caring Response Scoring System derived from Swanson's Caring Theory was used to code parent communication behaviors as caring responses during their children's port starts. Three 3- to 5-minute slices (pre-port start, during, and post-port start) were coded for each video. Mixed modeling with generalized estimating equations and Friedman test were used to analyze longitudinal change in parent behaviors.

RESULTS

Significant differences were found between T1 versus T3 in eye contact (β = -1.05, p = .02), distance-close-enough-to-touch (β = -0.81, p = .03), nonverbal comforting (β = -1.34, p = .04), and availability (β = -0.92, p = .036), suggesting that more parents used communication behaviors at T3 compared with T1. Parent burdensome or intrusive questions (e.g., Why do you cry? β = -1.11, p = .03) and nonverbal comforting (β = -1.52, p = .047) increased from T2 to T3. The median values of parent communication behaviors overall had no significant changes from T1 to T3.

CONCLUSION

Parents adjusted to use more nonverbal caring behaviors as their child experienced additional port starts. Experimental studies should be designed to help parents use caring behaviors to better support their children during cancer procedures.

The Detroit Research on Cancer Survivors (ROCS) study: A focus on outcomes after cancer in a racially diverse patient population

177

Background: Although we continue to make progress in reducing the incidence and mortality for most cancers in the United States, African Americans (AA) continue to experience higher cancer incidence rates and have worse survival than other populations. The causes of these poorer outcomes, from higher mortality to poorer quality of life, in AA cancer survivors are not well understood. The Detroit ROCS study was initiated to improve our understanding of the experience of AAs living with cancer. Methods: 1,000 AA and non-Hispanic white (NHW) patients with primary lung, female breast, prostate or colorectal cancer diagnosed on or after January 1, 2013, and/or treated at the Karmanos Cancer Institute in Detroit, MI were recruited to participate in a cohort study with planned follow-up for 4 years. At baseline, participants completed a web-based survey to gather information about their medical history, family history of cancer, treatment and medication use, behavioral risk factors and self-assessed quality of life. Statistical analyses were performed to examine racial differences in the distribution of patient characteristics including comorbid conditions, stage at diagnosis, first course treatment and reported health-related quality of life (HRQOL). Results: The majority of patients were AA (60%) and female (61%), with a median age at diagnosis of 60 years. AAs were older, more likely to report use of cigarettes and alcohol and report a greater number of comorbidities compared with NHW patients; they were less educated and less likely to be employed full time or married (all p-values < 0.001). AA patients reported poorer overall HRQOL compared with NHW patients (p-value < 0.001). Controlling for marital status and employment attenuated the observed racial differences in mean HRQOL scores across all measured domains. Conclusions: We observed significantly lower self-reported HRQOL among AA cancer survivors compared with NHW, which could be partially explained by differences in specific socioeconomic factors but interestingly, not the presence of multiple comorbidities. Future research efforts will evaluate the relative contribution of social and financial support to HRQOL in AAs.

Material and behavioral financial hardship as predictors of health-related quality of life in a diverse cohort of cancer survivors

145

Background: Financial hardship is common among cancer survivors, but its association with health-related quality of life (HRQOL) unknown. Methods: We utilized data from 570 black participants the Detroit Research on Cancer Survivors (ROCS) cohort study diagnosed with breast, colorectal, lung or prostate cancer since 1/1/13 and diagnosed or treated at the Karmanos Cancer Institute, and 402 white survivors meeting the same criteria. HRQOL was measured using the functional assessment of cancer therapy-general (FACT-G) and its subscales of physical, social, emotional and functional wellbeing, and site-specific measures. We fit linear regressions to estimate associations between material (debt, borrowing, selling assets, reduced income) and behavioral (skipping medication, not seeing a doctor, refusing treatment due to cost) financial hardship (MFH and BFH, respectively) and HRQOL. Adjusted models include demographic, socioeconomic, and treatment-related factors. Results: Overall, 50.3% of participants experienced material and 17.6% experienced behavioral financial hardship. In unadjusted models, HRQOL scores were 0.39 (95% CI 0.27, 0.51) standard deviations (SD) lower in those reporting any MFH. MFH was associated with significantly lower physical, emotional, and functional wellbeing scores, and with lower scores on breast-, colorectal-, and prostate-specific HRQOL measures. Total HRQOL was 0.68 SD (95% CI 0.52, 0.84) lower for participants who reported BFH than those who did not, and BFH was inversely associated with each subscale and each cancer-specific measure. In adjusted models, HRQOL scores were 0.15 (95% CI 0.03, 0.27) SD lower among participants reporting MFH and remained inversely associated with physical and functional wellbeing. BFH was associated with 0.42 (95% CI 0.27, 0.57) SD lower HRQOL scores and remained inversely associated with physical, social, emotional, and functional wellbeing; and with breast- and prostate-specific measures. Conclusions: MFH and BFH are associated with lower HRQOL among diverse cancer survivors. Addressing BFH in particular may improve HRQOL among survivors, particularly those with breast and prostate cancer.

Parents' Verbal and Nonverbal Caring Behaviors and Child Distress During Cancer-Related Port Access Procedures: A Time-Window Sequential Analysis

PURPOSE/OBJECTIVES

To study the relationship between parental verbal and nonverbal caring behaviors and child distress during cancer-related port access placement using correlational and time-window sequential analyses.
.

DESIGN

Longitudinal, observational design.
.

SETTING

Children's Hospital of Michigan and St. Jude Children's Research Hospital.
.

SAMPLE

43 child-parent dyads, each with two or three video recordings of the child undergoing cancer-related port placement.
.

METHODS

Two trained raters coded parent interaction behaviors and child distress using the Parent Caring Response Scoring System and Karmanos Child Coping and Distress Scale, respectively. Mixed modeling with generalized estimating equations examined the associations between parent interaction behaviors and parent distress, child distress, and child cooperation reported by multiple raters. Time-window sequential analyses were performed to investigate the temporal relationships in parent-child interactions within a five-second window.
.

MAIN RESEARCH VARIABLES

Parent caring behaviors, child distress, and child cooperation.
.

FINDINGS

Parent caring interaction behaviors were significantly correlated with parent distress, child distress, and child cooperation during repeated cancer port accessing. Sequential analyses showed that children were significantly less likely to display behavioral and verbal distress following parent caring behaviors than at any other time. If a child is already distressed, parent verbal and nonverbal caring behaviors can significantly reduce child behavioral and verbal distress.
.

CONCLUSIONS

Parent caring behaviors, particularly the rarely studied nonverbal behaviors (e.g., eye contact, distance close to touch, supporting/allowing), can reduce the child's distress during cancer port accessing procedures.
.

IMPLICATIONS FOR NURSING

Studying parent-child interactions during painful cancer-related procedures can provide evidence to develop nursing interventions to support parents in caring for their child during painful procedures.

Parent Caring Response Scoring System: development and psychometric evaluation in the context of childhood cancer-related port starts

RATIONALE

Multiple observational coding systems have been developed and validated to assess parent-child interactions during painful procedures. Most of these coding systems are neither theory-based nor do they well represent parent nonverbal behaviours.

AIMS

Develop the Parent Caring Response Scoring System (P-CaReSS) based on Swanson's Theory of Caring and test its psychometric properties in children in cancer port starts.

METHODS

A hybrid approach of inductive and deductive coding was used to formulate the preliminary observational codes for the P-CaReSS. Twenty-nine children, each with one video-recording of port start available, were selected from the parent study (R01CA138981) to refine the P-CaReSS, train coders and test inter-rater reliability. Videos of another 43 children were used to evaluate the construct validity of P-CaReSS. Per cent agreement and Cohen's kappa were used to present the inter-rater reliability. Spearman rank-order correlations were used to report the construct validity.

RESULTS

The 18-item P-CaReSS includes three types of parent behaviours: verbal, nonverbal and emotional behaviours. These parent interaction behaviours comprise five caring domains - knowing, being with, doing for, enabling, and maintaining belief - and one noncaring domain. On average the per cent agreement was 0.82 for the P-CaReSS overall, with average per cent agreements above 0.80 for both verbal and nonverbal behaviours. Kappa coefficient was 0.81 for the emotional behaviour. The behavioural codes in the P-CaReSS showed significant correlations with independent ratings of parent distress, child distress and child cooperation.

CONCLUSIONS

The P-CaReSS is a promising tool that can be used to evaluate parent verbal, nonverbal and emotional behaviours during cancer-related port starts. This observational tool can be used to guide the development of nursing interventions to help parents caring for their child during cancer procedures.

The impact of Black cancer patients' race-related beliefs and attitudes on racially-discordant oncology interactions: A field study

OBJECTIVE

Both physician and patient race-related beliefs and attitudes are contributors to racial healthcare disparities, but only the former have received substantial research attention. Using data from a study conducted in the Midwestern US from 2012 to 2014, we investigated whether 114 Black cancer patients' existing race-related beliefs and attitudes would predict how they and 18 non-Black physicians (medical oncologists) would respond in subsequent clinical interactions.

METHOD

At least two days before interacting with an oncologist for initial discussions of treatment options, patients completed measures of perceived past discrimination, general mistrust of physicians, and suspicion of healthcare systems; interactions were video-recorded. Measures from each interaction included patients' verbal behavior (e.g., level of verbal activity), patients' evaluations of physicians (e.g., trustworthiness), patients' perceptions of recommended treatments (e.g., confidence in treatment), physicians' evaluations of patient personal attributes (e.g., intelligence) and physicians' expectations for patient treatment success (e.g., adherence).

RESULTS

As predicted, patients' race-related beliefs and attitudes differed in their associations with patient and physician responses to the interactions. Higher levels of perceived past discrimination predicted more patient verbal activity. Higher levels of mistrust also predicted less patient positive affect and more negative evaluations of physicians. Higher levels of suspicion predicted more negative evaluations of physicians and recommended treatments. Stronger patient race-related attitudes were directly or indirectly associated with lower physician perceptions of patient attributes and treatment expectations.

CONCLUSION

Results provide new evidence for the role of Black patients' race-related beliefs and attitudes in racial healthcare disparities and suggest the need to measure multiple beliefs and attitudes to identify these effects.

Randomized trial of a question prompt list to increase patient active participation during interactions with black patients and their oncologists

OBJECTIVE

Communication during racially-discordant interactions is often of poor quality and may contribute to racial treatment disparities. We evaluated an intervention designed to increase patient active participation and other communication-related outcomes during interactions between Black patients and non-Black oncologists.

METHODS

Participants were 18 non-Black medical oncologists and 114 Black patients at two cancer hospitals in Detroit, Michigan, USA. Before a clinic visit to discuss treatment, patients were randomly assigned to usual care or to one of two question prompt list (QPL) formats: booklet (QPL-Only), or booklet and communication coach (QPL-plus-Coach). Patient-oncologist interactions were video recorded. Patients reported perceptions of the intervention, oncologist communication, role in treatment decisions, and trust in the oncologist. Observers assessed interaction length, patient active participation, and oncologist communication.

RESULTS

The intervention was viewed positively and did not increase interaction length. The QPL-only format increased patient active participation; the QPL-plus-Coach format decreased patient perceptions of oncologist communication. No other significant effects were found.

CONCLUSION

This QPL booklet is acceptable and increases patient active participation in racially-discordant oncology interactions. Future research should investigate whether adding physician-focused interventions might improve other outcomes.

PRACTICE IMPLICATIONS

This QPL booklet is acceptable and can improve patient active participation in racially-discordant oncology interactions.

Abstract A84: Perceived Social Support Moderates the Associations between Race-Based Medical Suspicion and Perceptions of Cancer Treatment

Background: Decades of research have demonstrated the salutary effects of higher perceived social support on thoughts and feelings about one's health. Separate work has shown that Black patients with higher race-based medical suspicion have more negative perceptions of their healthcare. Prior studies have not systematically investigated the extent to which perceived social support is related to medical suspicion in Black cancer populations. Purpose: We specifically explored whether larger social network size and higher social support satisfaction moderated negative perceptions and feelings typically experienced by Black patients scoring high on suspicion. Methods: 114 Black cancer patients reported their social support and suspicion at a baseline session. One week later, they interacted with their oncologist about initial treatment options during a clinic visit. Following the interaction, patients reported their uncertainty regarding the recommended treatment, perceived difficulty completing treatment, and distress. Results: Moderation results showed that larger social network size was related to less uncertainty and less perceived difficulty completing treatment for Black patients low in suspicion. However, larger social network size failed to reduce uncertainty and perceived difficulty and exacerbated distress for Black patients high in suspicion. Social support satisfaction moderated only the relation between medical suspicion and perceived difficulty. Conclusions: Social support is associated with distinct cancer treatment perceptions for Black cancer patients as a function of patients' suspicion, which may be explained by entrenchment in a social network that reinforces negative personal biases.

The Effects of Oncologist Implicit Racial Bias in Racially Discordant Oncology Interactions

PURPOSE

Health providers' implicit racial bias negatively affects communication and patient reactions to many medical interactions. However, its effects on racially discordant oncology interactions are largely unknown. Thus, we examined whether oncologist implicit racial bias has similar effects in oncology interactions. We further investigated whether oncologist implicit bias negatively affects patients' perceptions of recommended treatments (i.e., degree of confidence, expected difficulty). We predicted oncologist implicit bias would negatively affect communication, patient reactions to interactions, and, indirectly, patient perceptions of recommended treatments.

METHODS

Participants were 18 non-black medical oncologists and 112 black patients. Oncologists completed an implicit racial bias measure several weeks before video-recorded treatment discussions with new patients. Observers rated oncologist communication and recorded interaction length of time and amount of time oncologists and patients spoke. Following interactions, patients answered questions about oncologists' patient-centeredness and difficulty remembering contents of the interaction, distress, trust, and treatment perceptions.

RESULTS

As predicted, oncologists higher in implicit racial bias had shorter interactions, and patients and observers rated these oncologists' communication as less patient-centered and supportive. Higher implicit bias also was associated with more patient difficulty remembering contents of the interaction. In addition, oncologist implicit bias indirectly predicted less patient confidence in recommended treatments, and greater perceived difficulty completing them, through its impact on oncologists' communication (as rated by both patients and observers).

CONCLUSION

Oncologist implicit racial bias is negatively associated with oncologist communication, patients' reactions to racially discordant oncology interactions, and patient perceptions of recommended treatments. These perceptions could subsequently directly affect patient-treatment decisions. Thus, implicit racial bias is a likely source of racial treatment disparities and must be addressed in oncology training and practice.

Self-distancing Buffers High Trait Anxious Pediatric Cancer Caregivers against Short- and Longer-term Distress

Pediatric cancer caregivers are typically present at their child's frequent, invasive treatments, and such treatments elicit substantial distress. Yet, variability exists in how even the most anxious caregivers cope. Here we examined one potential source of this variability: caregivers' tendencies to self-distance when reflecting on their feelings surrounding their child's treatments. We measured caregivers' self-distancing and trait anxiety at baseline, anticipatory anxiety during their child's treatment procedures, and psychological distress and avoidance three months later. Self-distancing buffered high (but not low) trait anxious caregivers against short- and long-term distress without promoting avoidance. These findings held when controlling for other buffers, highlighting the unique benefits of self-distancing. These results identify a coping process that buffers vulnerable caregivers against a chronic life stressor while also demonstrating the ecological validly of laboratory research on self-distancing. Future research is needed to explicate causality and the cognitive and physiological processes that mediate these results.

Satisfaction with support versus size of network: differential effects of social support on psychological distress in parents of pediatric cancer patients

OBJECTIVE

This study examined the direct and buffering effects of social support on longer-term global psychological distress among parents coping with pediatric cancer. In both sets of analyses, we examined whether these effects depended on the dimension of social support provided (i.e., satisfaction with support versus size of support network).

METHOD

Participants were 102 parents of pediatric cancer patients. At study entry, parents reported their trait anxiety, depression, and two dimensions of their social support network (satisfaction with support and size of support network). Parents subsequently reported their psychological distress in 3- and 9-month follow-up assessments.

RESULTS

Parents' satisfaction with support had a direct effect on longer-term psychological distress; satisfaction was negatively associated with distress at both follow-ups. In contrast, size of support network buffered (moderated) the impact of trait anxiety and depression on later distress. Parents with smaller support networks and higher levels of trait anxiety and depression at baseline had higher levels of psychological distress at both follow-ups; for parents with larger support networks, there was no relationship.

CONCLUSION

Social support can attenuate psychological distress in parents coping with pediatric cancer; however, the nature of the effect depends on the dimension of support. Whereas interventions that focus on increasing satisfaction with social support may benefit all parents, at-risk parents will likely benefit from interventions that ensure they have an adequate number of support resources.

Patient- and Family-Centered Care as an approach to reducing disparities in asthma outcomes in urban African American children: A review of the literature

We thank Cathy Eames (Director, Library Services, Detroit Medical Center) for valuable input and assistance with the search strategy. Funding for this research was supported by a grant from Children's Hospital of Michigan Research Foundation (Principal Investigator: Terrance L. Albrecht, Ph.D.).

BACKGROUND

Patient- and family-centered care (PFCC) has the potential to address disparities in access and quality of healthcare for African American pediatric asthma patients by accommodating and responding to the individual needs of patients and families.

STUDY OBJECTIVES

To identify and evaluate research on the impact of family-provider interventions that reflect elements of PFCC on reducing disparities in the provision, access, quality, and use of healthcare services for African American pediatric asthma patients.

METHODS

Electronic searches were conducted using PubMed, CINAHL, and Psyclnfo databases. Inclusion criteria were peer-reviewed, English-language articles on family-provider interventions that (a) reflected one or more elements of PFCC and (b) addressed healthcare disparities in urban African American pediatric asthma patients (≤18years).

RESULTS

Thirteen interventions or programs were identified and reviewed. Designs included randomized clinical trials, controlled clinical trials, pre- and post-interventions, and program evaluations.

CONCLUSIONS

Few interventions were identified as explicitly providing PFCC in a pediatric asthma context, possibly because of a lack of consensus on what constitutes PFCC in practice. Some studies have demonstrated that PFCC improves satisfaction and communication during clinical interactions. More empirical research is needed to understand whether PFCC interventions reduce care disparities and improve the provision, access, and quality of asthma healthcare for urban African American children.

Temperament, personality, and quality of life in pediatric cancer patients

OBJECTIVE

The developmental psychology literature shows that children with higher levels of effortful control (EC) and ego-resilience (ER) display greater social competence and better emotional adjustment. This study examined whether these dispositional attributes contribute to positive quality of life (QOL) in pediatric cancer patients.

METHOD

Participants were 103 pediatric cancer patients (and their parents) who were part of a larger parent study. At study entry, parents reported their own anxiety and depression and their children's EC and ER. At 3-month follow-up, parents reported children's QOL.

RESULTS

ER was positively correlated with children's QOL. EC showed a positive indirect effect on QOL through ER. Inclusion of potential correlates of pediatric QOL (e.g., parent neuroticism) did not change these relationships.

CONCLUSIONS

Temperament and personality play significant roles in pediatric cancer patients' QOL. Assessing dispositional attributes early in treatment may help identify children at risk for poor QOL during and after treatment.

Posttraumatic Stress Symptoms in Parents of Pediatric Cancer Patients: A Mediational Analysis

OBJECTIVE

Prior research finds that anxiety and depression among parents of pediatric cancer patients are associated with posttraumatic stress symptoms in response to children's cancer. This study examined whether this relationship is mediated by parents' negative affective reactions in response to their children's cancer-related treatment procedures.

METHODS

Participants were parents of 101 patients within six months of diagnosis who had completed at least two treatment-related procedures. Parents completed measures of trait anxiety and depression at baseline and posttraumatic stress symptoms at 3-month follow-up assessment. On the day of each treatment procedure, parents completed measures of state anxiety immediately before and negative mood and distress immediately after the procedure.

RESULTS

Trait anxiety was positively associated with state anxiety immediately before procedures and negative mood after procedures. Depression was positively associated with state anxiety immediately before procedures and negative mood and distress after procedures. Both trait anxiety and depression were positively associated with posttraumatic stress symptoms at 3-months follow-up. Parent state anxiety, negative mood, and distress partially mediated the effects of trait anxiety and/or depression on posttraumatic stress symptoms. Controlling for child age and social desirability did not affect these relationships.

CONCLUSIONS

Parents' trait anxiety and depression may influence cancer-related posttraumatic stress partially through their effect on parents' negative affective reactions at the time of their child's treatment procedures. These findings provide a more nuanced understanding of how parents' affect in response to procedures contributes to parent posttraumatic stress and suggest that interventions targeting treatment-related affective reactions of parents with high trait anxiety and/or depression may reduce the risk for longer-term distress and posttraumatic stress symptoms.

Parent caregiver self-efficacy and child reactions to pediatric cancer treatment procedures

This study examined how parents' sense of self-efficacy specific to caregiving for their child during cancer treatment procedures affected children's distress and cooperation during procedures. Potential correlates of caregiver self-efficacy (ie, demographics, child clinical characteristics, parent dispositional attributes, and social support) were also examined. Participants were 119 children undergoing cancer treatment procedures and their parents. Parents' self-efficacy about 6 procedure-specific caregiver tasks was measured. Parents, children, nurses, and observers rated child distress and parents, nurses and observers rated child cooperation during procedures. Higher parent self-efficacy about keeping children calm during procedures predicted lower child distress and higher child cooperation during procedures. Parent dispositional attributes (eg, enduring positive mood, empathy) and social support predicted self-efficacy. Parent caregiver self-efficacy influences child distress and cooperation during procedures and is associated with certain parent attributes. Findings suggest the utility of identifying parents who would benefit from targeted interventions to increase self-efficacy about caregiving during treatment procedures.

The importance of contextual factors and age in association with anxiety and depression in Black breast cancer patients

OBJECTIVES

Limited research exists on correlates of psychosocial distress in Black breast cancer patients. The goals of the study were to describe the prevalence of distress (anxiety and depression) in Black women with breast cancer and to examine the influence of demographic, clinical, contextual (e.g., self-efficacy, medical mistrust), and process of care factors (e.g., patient satisfaction) on women's level of anxiety and depression.

METHODS

Eighty-two Black women diagnosed with invasive non-metastatic breast cancer were interviewed by phone. Collected data included demographic, clinical, contextual, and process of care factors. Bivariate correlations were used to examine relationships between those variables. Multiple linear regressions were used to examine predictors of anxiety and depression.

RESULTS

About one-third of the women (32%) met cut-off thresholds for distress. Medical mistrust and positive attitude had significant influences on anxiety levels, whereas age and positive attitude were determinants of levels of depression. Participants with higher medical mistrust reported more anxiety (r = .379; p < .001) and depression (r = .337; p = .002), whereas women with higher self-efficacy reported less anxiety (r = -.401; p < .001) and depression (r = -.427; p < .001). Age was inversely related to both anxiety and depression (r = -.224; r = -.296, respectively; p < .05).

CONCLUSIONS

Findings support national recommendations for routine distress screening in the delivery of cancer care particularly in younger Black patients. Interventions targeted to boost self-efficacy or reduce medical mistrust through enhanced patient-provider interactions may decrease psychological distress. Psychosocial needs of younger patients warrant particular attention.

Basic needs of pediatric oncology patients, families, and their psychosocial adjustment

e20646

Background: Children are surviving cancer at increasing rates, but dealing with pediatric cancer creates substantial need for services among the families of patients. This study examined the fiscal/material/social needs of families with children in treatment, the relationship between the extent of these needs, and the psychosocial adjustment of primary caregivers. Methods: Participants included 105 pediatric cancer patients (ages 3-12), receiving outpatient cancer treatments at two large children’s hospitals, and their adult caregivers. About one year after treatment began, caregivers completed a questionnaire assessing their fiscal/material/social needs and whether the hospital offered assistance. Caregivers also completed several measures of psychosocial adjustment: satisfaction with life (Diener, 1985), perceived stress (Cohen, 1994), psychiatric symptoms (Derogatis, 1983), and post-traumatic stress symptoms (Weiss, 1996). This non-clinical study is still accruing patients, but it has reached a sample size that is large enough (90% of final sample) to justify data analysis. Results: The top 5 identified needs were: social work services, play activities during treatment, help with insurance to cover their child’s medical care, educational activities to help their child cope, and help obtaining cancer-related medical services. An analysis of the demographic correlates of these needs showed the total number of needs was significantly and negatively correlated with income, and Black families reported more needs than White families; there were no other significant demographic correlates. Total number of needs was significantly associated with caregivers’ psychosocial adjustment. Specifically, total number of needs was negatively correlated with life satisfaction, and positively associated with: caregiver perceived stress, depression, and symptoms of post-traumatic stress. Conclusions: Caregivers of pediatric cancer patients have substantial needs for basic services and the extent of these needs is associated with their psychosocial adjustment. Unmet needs may be a risk factor for patients and families. Programs that address these needs may benefit the adult caregivers and their children.

Narrowing racial gaps in breast cancer chemotherapy initiation: the role of the patient-provider relationship

Chemotherapy improves breast cancer survival but is underused more often in black than in white women. We examined associations between patient-physician relationships and chemotherapy initiation and timeliness of initiation among black and white patients. Women with primary invasive, non-metastatic breast cancer were recruited via hospitals (in Washington, DC and Detroit) and community outreach between July 2006 and April 2011. Data were collected via telephone interviews and medical records. Logistic regression models evaluated associations between chemotherapy initiation and independent variables. Since there were race interactions, analyses were race-stratified. Factors associated with time from surgery to chemotherapy initiation and delay of ≥90 days were evaluated with linear and logistic regressions, respectively. Among eligible women, 82.8 % were interviewed and 359 (90.9 %) of those had complete data. The odds of initiating chemotherapy were 3.26 times (95 % CI: 1.51, 7.06) higher among black women reporting greater communication with physicians (vs. lesser), after considering covariates. In contrast, the odds of starting chemotherapy were lower for white women reporting greater communication (vs. lesser) (adjusted OR 0.22, 95 % CI: 0.07, 0.73). The opposing direction of associations was also seen among the sub-set of black and white women with definitive clinical indications for chemotherapy. Among those initiating treatment, black women had longer mean time to the start of chemotherapy than whites (71.8 vs. 55.0 days, p = 0.005), but race was not significant after considering trust in oncologists, where initiation time decreased as trust increased, controlling for covariates. Black women were also more likely to delay ≥90 days than whites (27 vs. 8.3 %; p = 0.024), but this was not significant after considering religiosity. The patient-physician dyad and sociocultural factors may represent leverage points to improve chemotherapy patterns in black women.

Children's positive dispositional attributes, parents' empathic responses, and children's responses to painful pediatric oncology treatment procedures

Pain/distress during pediatric cancer treatments has substantial psychosocial consequences for children and families. The authors examined relationships between children's positive dispositional attributes, parents' empathic responses, and children's pain/distress responses to treatment procedures. Participants were 41 pediatric cancer patients and parents. Several weeks before treatment, parents rated children's resilience and positive dimensions of temperament. Parents' pretreatment empathic affective responses to their children were assessed. Children's pain/distress during treatments was rated by multiple independent raters. Children's resilience was significantly and positively associated with parents' empathic affective responses and negatively associated with children's pain/distress. Children's adaptability and attention focusing also showed positive relationships (p < 0.10) with parents' empathic responses. Parents' empathic responses mediated effects of children's resilience on children's pain/distress. Children's positive dispositional attributes influence their pain/distress during cancer treatments; however, these effects may be mediated by parents' empathic responses. These relationships provide critical understanding of the influence of parent-child relationships on coping with treatment.

Longitudinal study of parent caregiving self-efficacy and parent stress reactions with pediatric cancer treatment procedures

BACKGROUND

Pain/distress during pediatric cancer treatments has substantial psychosocial consequences for children and families. We examined relationships between parents' caregiving self-efficacy, parents' affect in response to their children's cancer-related treatment procedures, and parents' symptoms of post-traumatic stress at follow-up.

METHODS

Participants were 75 pediatric cancer patients and parents. On the day of each of three procedures (i.e., port-start, lumbar puncture, or bone marrow aspiration), parents rated their self-efficacy for six caregiving goals. Parents also self-reported their negative affect (i.e., state anxiety, negative mood, and distress) in response to each procedure. Three months after the last procedure, parents reported their level of post-traumatic stress symptoms (PTSS).

RESULTS

Higher parent self-efficacy about keeping children calm before treatment and/or keeping children calm during the procedure was associated with lower state anxiety. Self-efficacy for keeping the child calm during procedures was significantly correlated with distress in parents at the time of procedures, and self-efficacy for keeping the child calm before procedures was significantly correlated with PTSS. All three negative affect measures significantly mediated the effects of parents' caregiving self-efficacy for both goals on parents' PTSS 3 months later.

CONCLUSIONS

Parents' caregiving self-efficacy influences their immediate and longer-term distress reactions to their children's treatment procedures. These findings provide a more nuanced understanding of how parents' cognitions contribute to their ability to cope with their children's treatment and suggest the benefit of an intervention that targets parents' procedure-specific caregiver self-efficacy.

Patient, companion, and oncologist agreement regarding information discussed during triadic oncology clinical interactions

BACKGROUND

Although people with cancer want and need information from their oncologists, patients and oncologists often disagree about what information was discussed during clinical interactions. Most patients have companions present during oncology visits; we investigated whether companions process information more accurately than patients. Specifically, we examined whether patients and companions differed in agreement with oncologists about what was discussed. We also investigated the effect of topic on agreement and patient/companion self-reported understanding of discussions.

METHODS

Patients with companions were invited to participate on first visits to a cancer center in Detroit, MI. Patients, companions, and oncologists independently completed questionnaires immediately following visits. Participants were asked whether five topics were discussed (diagnosis, prognosis, metastasis, treatment/treatment goals, and side effects) and, if discussed, what oncologists said. Participants were also asked to estimate their own and each other's understanding of discussions.

RESULTS

A total of 66 patient-companion-oncologist triads participated. Agreement was higher regarding whether topics were discussed than what oncologists said. Agreement did not differ by dyad type. Patients, companions, and oncologists were equally likely to be the source of triadic disagreements. Agreement was high about diagnosis (>90%) but much lower about other topics, particularly side effects. Patients and companions reported greater understanding of discussions than oncologists estimated and more accurately estimated each other's understanding than did oncologists.

CONCLUSIONS

Companions and patients showed similar levels of agreement with oncologists about what they discussed during visits. Interventions are needed to improve communication of information to both patients and companions, especially about particular topics.

Physicians' Use of Patients' Daily Reports of Quality of Life to Evaluate Treatment Response in Phase I Cancer Trials

For cancer patients on Phase I trials, one of the most important physician decisions is whether or not patients are deriving benefit from therapy. With an increasing number of cytostatic treatment agents, the criteria to determine patient response to Phase I treatment has become harder to define. Physicians are increasingly looking to patient-reported outcomes (PROs) such as quality of life (QOL) to help evaluate treatment response. Electronic daily diary (EDD) devices can be used by patients to report their QOL over extended periods of time, thereby providing a more accurate picture of how patients are affected by treatment on a daily basis. However, questions remain about how to integrate this patient-reported information into decisions about Phase I treatment. This study investigated how physicians use patients' daily QOL reports to evaluate patient response to Phase I treatment. Data were collected over a 4-month period from Phase I patients (N = 30) and physicians (N = 3) in an NCI-designated comprehensive cancer center. Patients completed daily QOL reports using EDD devices and physicians were provided with a summary of patients' QOL before each visit. After the visit, doctors recorded their treatment decision and also rated the importance of four biomedical factors (Toxicity, Imaging, Labs, and Performance Status) and QOL in their treatment decision for that visit. Although physicians rated QOL as being very important in evaluating treatment response, in practice, when predictors of their decisions were analyzed, results showed they relied exclusively on biomedical data (Toxicity, Imaging) to make Phase I treatment decisions. Questions remain about the utility and effective integration of QOL and biomedical data in clinical decision-making processes in Phase I clinical trials.

Variation in question asking during cancer clinical interactions: a potential source of disparities in access to information

OBJECTIVE

to investigate whether patient demographic characteristics and patients' companions influence variation in patient question asking during cancer clinical interactions, thus representing a potential disparity in access to information.

METHODS

data included 109 oncologist-patient-companion interactions video recorded at a comprehensive cancer center. Interactions were observed and analyzed using the Karmanos Information Seeking Analysis System (K-ISAS).

RESULTS

significant relationships were found between patient race/ethnicity and question asking. Black patients asked fewer questions and a smaller proportion of direct questions (relative to the total frequency of questions) than White patients. Black patients were also less likely to have companions present during the interaction, which resulted in fewer questions asked on Black patients' behalf.

CONCLUSION

differences in question asking by Black and White patients suggest that Black patients may receive less information from their oncologists than White patients. PRACTICE/RESEARCH IMPLICATIONS: patients should be encouraged to ask more questions and more direct questions and to bring a companion to the interaction to assist them in gaining information from their physician. Future research is needed to investigate ways to eliminate this potential source of disparities in access to information.

The influence of patient expectations regarding cure on treatment decisions

OBJECTIVE

To test whether cancer patients' expectations for cure prior to interacting with their oncologist influence their decisions to follow treatment recommendations. Further, to test whether patients' expectations for cure are affected by the strength of the oncologist-patient alliance or the extent to which companions (if present) share patients' expectations for cure.

METHODS

Interactions of 101 patients (and 114 companions) with oncologists about treatment were coded for the strength of the oncologist-patient alliance. Prior to the interaction, patients and companions reported expectations about whether the patient would be cured of cancer. After the interaction, patients reported whether they intended to follow the recommended treatment.

RESULTS

Patients who expected a cure were more likely to report an intention to follow oncologists' treatment recommendation when the strength of their alliance with their oncologist was weaker (B=-0.51, p<.05). Patients whose expectations for cure matched their companions' expectations were less likely to report intentions to follow treatment recommendations (B=-0.28, p<.05).

CONCLUSION

Patients who have an expectation of being cured of cancer prior to meeting with their oncologist are more likely to intend to follow recommended treatment when their alliance with the oncologist is weaker and their companions do not believe they will be cured.

PRACTICE IMPLICATIONS

To better understand patient treatment decisions and improve overall cancer care, oncologists should be aware of the complex ways that patients' expectations about cure influence treatment choices.

Parents' Empathic Responses and Pain and Distress in Pediatric Patients

We investigated the relationship between parents' empathic responses prior to their children undergoing cancer treatment procedures and children's pain/distress during the procedures. We hypothesized: (1) parents' empathic distress would be positively associated with children's pain/distress, (2) parents' empathic concern would be negatively associated with children's pain/distress; and (3) parents' enduring dispositions and social support would be associated with their empathic responses. Parents completed: (1) measures of dispositions and perceived social support several weeks before their children underwent the procedures, and (2) state measures of empathic distress and empathic concern just before the procedures. Empathic distress was positively associated with children's pain; empathic concern was negatively associated with children's pain/distress. Predictions about dispositions and social support were also substantially confirmed.

Influence of clinical communication on patients' decision making on participation in clinical trials

PURPOSE

To investigate how communication among physicians, patients, and family/companions influences patients' decision making about participation in clinical trials.

PATIENTS AND METHODS

We video recorded 235 outpatient interactions occurring among oncologists, patients, and family/companions (if present) at two comprehensive cancer centers. We combined interaction analysis of the real-time video-recorded observations (collected at Time 1) with patient self-reports (Time 2) to determine how communication about trial offers influenced accrual decisions.

RESULTS

Clinical trials were explicitly offered in 20% of the interactions. When offers were made and patients perceived they were offered a trial, 75% of patients assented. Observed messages (at Time 1) directly related to patients' self-reports regarding their decisions (2 weeks later), and how they felt about their decisions and their physicians. Specifically, messages that help build a sense of an alliance (among all parties, including the family/companions), provide support (tangible assistance and reassurance about managing adverse effects), and provide medical content in language that patients and family/companions understand are associated with the patient's decision and decision-making process.

CONCLUSION

In two urban, National Cancer Institute-designated comprehensive cancer centers, a large percentage of patients are not offered trials. When offered a trial, most patients enroll. The quality and quantity of communication occurring among the oncologist, patient, and family/companion when trials are discussed matter in the patient's decision-making process. These findings can help increase physician awareness of the ways that messages and communication behaviors can be observed and evaluated to improve clinical practice and research.

Assessing perceptions of cancer risk: does mode of assessment or numeracy matter?

BACKGROUND

Many existing models of health behavior advance perceived risk for disease as a key motivator of risk-reduction behavior. Thus evaluating contextual factors that may influence assessment of perceived risk is important. We examined (1) how mode of assessment (mail, telephone, web-based) and numeracy affect reported estimates of perceived risk of colon cancer, and (2) how the amount of missing perceived risk data differs as a function of mode of assessment and numeracy.

METHOD

Women (N=457; mean age=61.3 years) with and without Internet access participated. Women without Internet access (n=233) were randomized into telephone or mail modes of assessment, and women with Internet access (n=224) were randomized into telephone, mail, or web-based modes of assessment. Numeracy and four different estimates of perceived lifetime risk for colon cancer (personal percentage, population percentage, comparative, binary) were assessed.

RESULTS

No significant differences were found in obtained risk estimates for any of the four risk perception items across the different modes of assessment. Greater numeracy was associated with lower percentage estimates of perceived risk. In general, the telephone mode of assessment yielded less missing data than the mail mode of assessment.

CONCLUSION

Mode of assessment largely does not matter when it comes to assessing perceived colon cancer risk. However, numeracy does matter and specifically impacts percentage estimates of perceived risk. While web-based, mail, and telephone modes may be used interchangeably when assessing perceived cancer risk; less missing data may result with telephone data collection.
