A cross-cultural validation of patient-reported outcomes measures: a study of breast cancers survivors

Correlates of health-related quality of life in African Americans diagnosed with cancer: a review of survivorship studies and the Detroit research on cancer survivors cohort

Advances in cancer screening and treatment have improved survival after a diagnosis of cancer. As the number of cancer survivors as well as their overall life-expectancy increases, investigations of health-related quality of life (HRQOL) are critical in understanding the factors that promote the optimal experience over the course of survivorship. However, there is a dearth of information on determinants of HRQOL for African American cancer survivors as the vast majority of cohorts have been conducted predominantly among non-Hispanic Whites. In this review, we provide a review of the literature related to HRQOL in cancer survivors including those in African Americans. We then present a summary of published work from the Detroit Research on Cancer Survivors (ROCS) cohort, a population-based cohort of more than 5000 African American cancer survivors. Overall, Detroit ROCS has markedly advanced our understanding of the unique factors contributing to poorer HRQOL among African Americans with cancer. This work and future studies will help inform potential interventions to improve the long-term health of this patient population.

The role of breast cancer-related arm lymphedema in physical functioning and physical activity participation among long-term African American breast cancer survivors

PURPOSE

Breast cancer-related arm lymphedema (BCRL) is a common chronic and debilitating condition that involves accumulation of lymphatic fluid in the arm or hand. Limited data are available on BCRL in African American women. Lack of physical activity (PA) and poor physical functioning (PF) are both associated with increased morbidity and mortality among breast cancer survivors. We examined the association of BCRL with PA and PF among African American breast cancer survivors.

METHODS

323 African American women who previously participated in a case-only study in three states (TN, GA, SC) completed a survivorship-focused questionnaire (mean: 4.2 years post-diagnosis) in 2015-2016. Validated measures were used to determine BCRL, PF, and PA. Adjusted binary logistic regression models estimated ORs and 95% CIs for the association of BCRL and meeting PA guidelines (≥ 150 min/week), while multinomial logistic regression was used for PF and PA (minutes/week) categorized based on tertiles.

RESULTS

Approximately 32% reported BCRL since diagnosis; 25.4% reported BCRL in the last 12-months. About 26% and 50% reported that BCRL interfered with exercise and ability to do daily activities, respectively. The mean PF among those with BCRL was 51.0(SD:29.0) vs. 68.5(SD:30.1) among those without BCRL. BCRL was associated with lower PF (adjusted-OR for tertile 2: 2.12(95% CI:1.03-4.36) and adjusted-OR for tertile 1: 2.93(95% CI:1.44-5.96)).

CONCLUSIONS

BCRL was associated with lower PF among long-term African American breast cancer survivors. Continued monitoring by health care professionals and increased education and behavioral interventions to support PA and improved PF among survivors living with BCRL are warranted.

Psychometric Properties of the Patient Health Questionnaire-9 in Patients With Breast Cancer

OBJECTIVE

Due to the high frequency of depressive symptoms associated with breast cancer, it is crucial to screen for depression in breast cancer patients. While numerous screening tools are available for depression in this population, there is a need for a brief and convenient tool to enhance clinical use. This study aims to investigate the psychometric properties of the Patient Health Questionnaire-9 (PHQ-9) in patients with breast cancer.

METHODS

Patients with breast cancer (n=327) who visited the Breast Cancer Clinic were included in this study. The reliability of the PHQ-9 was analyzed by Cronbach's α, and the construct validity of the PHQ-9 was explored by factor analysis. The concurrent validity of the PHQ-9 was evaluated by Pearson correlation analysis with the Hospital Anxiety and Depression Scale (HADS) and Perceived Stress Scale (PSS).

RESULTS

The values of Cronbach's α ranged from 0.800 to 0.879 was acceptable. The exploratory factor analysis revealed that the one-factor model and two-factor model of the PHQ-9 explained 46% and 57% of the variance, respectively. The PHQ-9 were significantly correlated with those of HADS (r=0.702, p<0.001) and PSS (r=0.466, p<0.001). Consequently, the PHQ-9 demonstrated acceptable reliability and validity in breast cancer patients.

CONCLUSION

The findings of this study indicate that the PHQ-9 exhibits acceptable reliability and validity in patients with breast cancer. The convenience of this brief self-report questionnaire suggests its potential as a reliable and valid tool for assessing depression in breast cancer clinics.

Attachment insecurity, heart rate variability, and perceived social support in a diverse sample of young adults

Psychological and physical factors are robustly associated with perceived social support. Drawing from the literature on attachment style in adults and psychophysiology, we examined the possibility that the interaction of attachment insecurity and resting heart rate variability (HRV) was associated with perceived social support in a diverse sample of young adults living in the U.S (N = 145, Mage = 20.45) that was majority Latino (n = 77). Analyses revealed three key findings. First, in the overall sample, attachment avoidance and attachment anxiety were negatively associated with perceived social support, but in the Latino sample, only attachment avoidance was negatively associated with perceived social support. Second, HRV was not associated with perceived social support in the overall sample nor in the Latino sample. Third, attachment insecurity and HRV interacted to predict perceived social support only in the Latino sample such that, for those with lower levels of HRV, attachment anxiety was positively associated with perceived social support. This study underscores the importance of examining both psychological and physiological processes with careful consideration of ethnicity/culture in order to better understand perceived social support.

Psychometric Properties of Assessment Tools for Depression, Anxiety, Distress, and Psychological Problems in Breast Cancer Patients: A Systematic Review

OBJECTIVE

Various and accurate psychiatric assessments in patients with breast cancer who frequently suffer from psychological problems due to long-term survivors are warranted. This systematic review aimed to investigate the current evidence on psychometric properties of psychiatric assessment for evaluating psychological problems in breast cancer patients.

METHODS

This systematic review progressed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Four electronic databases such as Web of Science, PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature were searched. This study protocol was registered on Open Science Framework.

RESULTS

Of the 2,040 articles, 21 papers were finally included. Among them, only five studies showed the performance of psychiatric assessment tools. Among 13 assessment tools used in the selected articles, the Hospital Anxiety and Depression Scale (HADS), Distress Thermometer (DT), or Mini-Mental Adjustment to Cancer Scale was frequently used for the evaluation of psychological problems. The DT and Psychosocial Distress Questionnaire-Breast Cancer showed acceptable performances for the prediction of depression and anxiety assessed by the HADS.

CONCLUSION

This systematic review found psychiatric assessment tools with acceptable reliability and validity for breast cancer patients. However, comparative studies on reliability and validity of various scales are required to provide useful information for the selection of appropriate assessment tools based on the clinical settings and treatment stages of breast cancer. Joint research among the fields of psychiatry and breast surgery is needed for research to establish the convergent, concurrent, and predictive validity of psychiatric assessment tools in breast cancer patients.

Medical outcomes study social support survey (MOS-SSS) in patients with chronic disease: A psychometric assessment

Purpose

Currently, information on the psychometric properties of the Medical outcomes study-social support survey (MOS-SSS) for patients with chronic disease in primary health care, suggests problems in the dimensionality, specifically predominant unidimensionality in a multidimensional measure. The aim of this study was to determine the internal structure (dimensionality, measurement invariance and reliability) and association with other variables.

Methods

A total of 470 patients with chronic disease from a Family Medicine Unit at the Instituto Mexicano del Seguro Social, IMSS, with a mean age of 51.51 years were included. Participants responded to the Questionnaire of Sociodemographic Variables (Q-SV), SF-36 Health-Related Quality of Life Scale-version 1.1, and MOS-SSS.

Results

Non-parametric (Mokken scaling analysis) and parametric (confirmatory factor analysis) analyses indicated unidimensionality, and three-factor model was not representative. A new 8-item version (MOS-S) was developed, where measurement invariance, equivalence with the long version, reliability, and relationship with the SF-36 were satisfactory.

Conclusion

The MOS-SSS scale is unidimensional, and the shortened version yields valid and reliable scores for measuring social support in patients with chronic disease at the primary health care.

Systematic Review of Breast-Q: A Tool to Evaluate Post-Mastectomy Breast Reconstruction

Purpose

The aim of this systematic review is to update and synthesize new evidence on BREAST-Q questionnaire’s ability to reflect patient-reported outcomes in women who have undergone breast reconstruction surgery (BRS) following mastectomy.

Methods

PubMed, Science Direct, Google Scholar, Cochrane CENTRAL, and Clincaltrial.gov were searched for relevant studies from January 2009 to September 2021. Any interventional or observational studies that used BREAST-Q to assess patient-reported outcomes in the assessment of BRS following mastectomy were included.

Results

A total of 42 studies were eligible for inclusion in the review. Three were randomized controlled trials and 39 were observational studies. Compared with pre-operative scores, there was an improvement in all BREAST-Q outcome domains following BRS including ‘satisfaction with breasts’, “satisfaction with outcome” “psychosocial”, “physical”, and “sexual wellbeing”. Sexual well-being had the lowest BREAST-Q score both pre-and post-operatively (37.8–80.0 and 39.0–78.0, respectively). Autologous BRS reports higher satisfaction and overall wellbeing compared to implant-based BRS. BREAST-Q has a higher and narrow internal consistency of 0.81 to 0.96 compared with other patient-reported outcome measures (PROMs; EORTC-QLQ, FACT-B, BR-23, BCTOS). The BREAST-Q questionnaire is the only PROM which allows patients to reflect on their care, surgical outcomes, and satisfaction collectively.

Conclusion

This review highlights the fact that BREAST-Q can effectively and reliably measure satisfaction and wellbeing of breast cancer patients after BRS. Comparatively, sexual wellbeing shows poorer outcomes following BRS and more longitudinal studies are necessary to understand the basis for these findings. Compared to other PROMs, BREAST-Q is reliable and specific to breast cancer surgery. Overall, BREAST-Q can help clinicians improve their quality of service, understand patient experiences, and may be used as an auditing tool for surgical outcomes.

Understanding the relationship between positive and negative social support and the quality of life among African American breast cancer survivors

PURPOSE

Social support improves several quality of life (QOL) domains among African American breast cancer survivors. How different dimensions of social support are associated with QOL among African American breast cancer survivors may however differ from other populations. This study explores this hypothesis by examining associations of positive social support (supportive interactions that promote affection) and negative social support (non-supportive interactions wherein the provider of support may not have the best intended actions) with QOL among Chicago-based African American breast cancer survivors.

METHODS

Study participants were eligible if they (1) were identified as being an African American female, (2) were at least 18 years of age or older, and (3) were diagnosed with breast cancer during or after navigation was implemented at the study hospital. Participants completed validated questionnaires via telephone or in-person interviews.

RESULTS

Among our sample of 100 participants, positive support was associated with greater mental well-being in non-imputed (Std β=1.60, CI: 0.51, 2.69, p= 0.004) and imputed models (Std β= 1.67, CI: 0.68, 2.73, p=0.001). There was also a weaker inverse association with negative support and mental well-being when using non-imputed data (Std β=-0.82, CI:-1.65, 0.02, p= 0.05).

CONCLUSIONS

Our findings suggest that positive support, in particular, is highly influential for improving mental well-being among African American breast cancer survivors. Simultaneously, negative support appears to be an independent, albeit weaker, determinant of mental well-being.

Addressing distress management challenges: Recommendations from the consensus panel of the American Psychosocial Oncology Society and the Association of Oncology Social Work

Distress management (DM) (screening and response) is an essential component of cancer care across the treatment trajectory. Effective DM has many benefits, including improving patients' quality of life; reducing distress, anxiety, and depression; contributing to medical cost offsets; and reducing emergency department visits and hospitalizations. Unfortunately, many distressed patients do not receive needed services. There are several multilevel barriers that represent key challenges to DM and affect its implementation. The Consolidated Framework for Implementation Research was used as an organizational structure to outline the barriers and facilitators to implementation of DM, including: 1) individual characteristics (individual patient characteristics with a focus on groups who may face unique barriers to distress screening and linkage to services), 2) intervention (unique aspects of DM intervention, including specific challenges in screening and psychosocial intervention, with recommendations for resolving these challenges), 3) processes for implementation of DM (modality and timing of screening, the challenge of triage for urgent needs, and incorporation of patient-reported outcomes and quality measures), 4) organization-inner setting (the context of the clinic, hospital, or health care system); and 5) organization-outer setting (including reimbursement strategies and health-care policy). Specific recommendations for evidence-based strategies and interventions for each of the domains of the Consolidated Framework for Implementation Research are also included to address barriers and challenges.

Psychometric properties and factor structure of the Medical Outcomes Study Social Support Survey Instrument in a sample of Spanish older adults

The aim of this study was to explore the factor structure of the MOS-SSS in a sample of community-dwelling Spanish older adults. The sample comprised 406 community-dwelling older adults aged between 65 to 99 years old (M _age = 74.88, SD = 6.75). Confirmatory factor analysis (CFA) was performed, and four possible models were compared: the one-factor, the three-factor, the four-factor and the five-factor model, using an additional analysis with a second-order factor. The internal consistency reliability and convergent validity of the scale were also assessed. For the 19-item MOS-SSS scale, the five-factor model had the best fit to the data. All five subscales of the MOS-SSS showed adequate internal consistency, good convergent and discriminant validity. These findings contribute to the literature on the factor structure of the MOS-SSS in Spanish older adults. The MOS-SSS is a reliable and valid scale that can be used to assess Spanish older adults' social support perception for social services, health and in research contexts.

Randomized controlled trial of a breast cancer Survivor Stories intervention for African American women

RATIONALE

Video-based interventions hold promise for improving quality of life (QoL) among African American breast cancer patients.

OBJECTIVE

An interactive, cancer-communication intervention using African American breast cancer survivors' narratives was tested in a randomized controlled trial to determine whether viewing survivor stories improved newly diagnosed African American breast cancer patients' QoL.

METHOD

Participants were 228 African American women with non-metastatic breast cancer interviewed five times over two years; 120 controls received standard medical care, and 108 intervention-arm participants also received a tablet-computer with survivor stories three times in 12 months. Growth curve models were used to analyze differences between arms in change in eight RAND 36-Item Health Survey subscales, depressive symptoms, and concerns about recurrence. Additional models explored the effects of intervention usage and other intervention-related variables on QoL among patients in the intervention arm.

RESULTS

Models showed no effect of study arm on QoL, depressive symptoms, or concerns about recurrence. Longer use of the intervention was associated with an increase in concerns about recurrence and decline in three QoL subscales: emotional wellbeing, energy/fatigue, and role limitations due to physical health.

CONCLUSION

Although no significant impact of the intervention on QoL was observed when comparing the two study arms, in the intervention arm longer intervention use was associated with declines in three QoL subscales and increased concerns about recurrence. Women with improving QoL may have interacted with the tablet less because they felt less in need of information; it is also possible that encouraging patients to compare themselves to survivors who had already recovered from breast cancer led some patients to report lower QoL. Future work is warranted to examine whether adding different stories to this cancer-communication intervention or using stories in conjunction with additional health promotion strategies (e.g., patient navigation) might improve QoL for African American breast cancer patients.

Methodology Aspects of Nausea Measuring During Pelvic Radiotherapy: Daily Nausea Measuring Is Successful to Identify Patients Experiencing Nausea

BACKGROUND

Nausea seems underreported during pelvic radiotherapy.

OBJECTIVE

The aims of this study were to investigate if a 5-week recall measure of nausea covering the entire radiotherapy period was comparable with accumulated daily nausea measurements and to investigate if the measuring method affected potential difference in quality of life (QoL) between nauseated patients and patients free from nausea.

METHODS

This longitudinal methodology study covered 200 patients (mean age, 64 years; 84% women; 69% had gynecological cancer). The patients graded QoL (Functional Assessment of Cancer Therapy-General). They registered nausea daily and at a 5-week recall at the end of radiotherapy.

RESULTS

The nausea-intensity category scale and visual analog scale correlated well (Spearman correlation coefficient = 0.622). According to the 5-week recall, 57 of 157 answering patients (36%) experienced nausea during the radiotherapy period. Using the daily nausea measurements, 94 of 157 patients (60%) experienced nausea (relative risk, 1.65; 95% confidence interval, 1.29-2.10). Of these 94 nauseated patients, 39 (42%) did not report nausea using the 5-week recall. The nauseated patients experienced worse QoL (physical/functional subscores) than patients free from nausea whether nausea was registered daily or at the 5-week recall.

CONCLUSIONS

Almost half, 42%, of the patients who experienced nausea according to daily nausea measurements did not report having had nausea according to the 5-week recall. Nauseated patients graded worse QoL than patients who were free from nausea.

IMPLICATIONS FOR PRACTICE

Nursing professionals should measure nausea repeatedly to identify patients at risk of nausea and worsened QoL, to be able to deliver evidence-based antiemetic treatment strategies.

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.

The impact of muscle relaxation techniques on the quality of life of cancer patients, as measured by the FACT-G questionnaire

INTRODUCTION

Patients with cancer frequently suffer from emotional distress, characterized by psychological symptoms such as anxiety or depression. The presence of psychological symptoms combined with the complex nature of oncology processes can negatively impact patients' quality of life. We aimed to determine the impact of a relaxation protocol on improving quality of life in a sample of oncological patients treated in the Spanish National Public Health System.

MATERIALS AND METHODS

We conducted a multicenter interventional study without a control group. In total, 272 patients with different oncologic pathologies and showing symptoms of anxiety were recruited from 10 Spanish public hospitals. The intervention comprised abbreviated progressive muscle relaxation training, according to Bernstein and Borkovec. This was followed by weekly telephone calls to each patient over a 1-month period. We collected sociodemographic variables related to the disease process, including information about mental health and the intervention. Patients' quality of life was assessed using the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire. Bivariate and univariate analyses were performed, along with an analysis of multiple correspondences to identify subgroups of patients with similar variations on the FACT-G.

RESULTS

Patients showed statistically significant improvements on the FACT-G overall score (W = 16806; p<0.001), with an initial mean score of 55.33±10.42 and a final mean score of 64.49±7.70. We also found significant improvements for all subscales: emotional wellbeing (W = 13118; p<0.001), functional wellbeing (W = 16155.5; p<0.001), physical wellbeing (W = 8885.5; p<0.001), and social and family context (W = -1840; p = 0.037).

CONCLUSIONS

Patients with cancer who learned and practiced abbreviated progressive muscle relaxation experienced improvement in their perceived quality of life as measured by the FACT-G. Our findings support a previous assumption that complementary techniques (including relaxation techniques) are effective in improving the quality of life of patients with cancer.

Perceived social support in African American breast cancer patients: Predictors and effects

RATIONALE

Social support plays an important role in quality of life and health outcomes after breast cancer diagnosis and treatment.

OBJECTIVE

To examine changes in perceived social support in African American women during the two years following a new breast cancer diagnosis.

METHODS

This secondary analysis uses data collected from 2009 to 2015 from 227 newly diagnosed, African American women with breast cancer (mean age 56 [SD = 10], 59% household income < $25,000; 28% married/partnered, 72% early stage) participating in a randomized controlled trial testing the effects of a video-communication intervention on quality-of-life and follow-up care. Participants, all of whom received treatment in one metropolitan area of the Midwestern United States, completed five telephone interviews over 2-year follow-up; demographic, psychosocial, quality of life, and clinical data were collected. Growth curve models were used to examine change in perceived social support (measured by the Medical Outcomes Study Social Support Survey) as well as correlates of baseline levels of social support and predictors of change in individuals' social support. Additional analyses examined whether change in social support over the first year affected depressive symptoms (Center for Epidemiologic Studies Depression Scale) and general health perceptions (RAND SF-36 subscale) at two years.

RESULTS

Being married, reporting greater spirituality, and reporting fewer depressive symptoms at baseline were significantly associated with higher initial levels of perceived social support. Women whose social support declined during the first year after diagnosis reported more severe depressive symptoms and worse general health perceptions at two years.

CONCLUSION

Clinicians should periodically assess perceived social support among African American women with breast cancer to help find support resources for those who have low initial social support and for those whose support declines in the first year after diagnosis.

Negative psychological consequences of breast cancer among recently diagnosed ethnically diverse women

OBJECTIVE

Breast cancer has psychological consequences that impact quality of life. We examined factors associated with negative psychological consequences of a breast cancer diagnosis, in a diverse sample of 910 recently diagnosed patients (378 African American, 372 white, and 160 Latina).

METHODS

Patients completed an in-person interview as part of the Breast Cancer Care in Chicago study within an average of 4 months from diagnosis. The Cockburn negative psychological consequences of breast cancer screening scale was revised to focus on a breast cancer diagnosis. Path analysis assessed predictors of psychological consequences and potential mediators between race/ethnicity and psychological consequences.

RESULTS

Compared to white counterparts, bivariate analysis showed African American (β = 1.4, P < .05) and Latina (β = 3.6, P < .001) women reported greater psychological consequences. Strongest predictors (P < .05 for all) included unmet social support (β = .38), and provider trust (β = .12), followed by stage at diagnosis (β = .10) and perceived neighborhood social disorder (β = .09).The strongest mediator between race/ethnicity and psychological consequences was unmet social support.

CONCLUSIONS

African American and Latina women reported greater psychological consequences related to their breast cancer diagnosis; this disparity was mediated by differences in unmet social support. Social support represents a promising point of intervention.

How Menopause Symptoms and Attitude Impact Korean Women's Quality of Life After Adjuvant Treatment for Breast Cancer

BACKGROUND

Attitudes toward menopause vary across cultures and influence women's experiences of menopausal symptoms, possibly leading to reduced posttreatment quality of life in breast cancer survivors.

OBJECTIVE

The aim of this study is to examine the effects of menopausal symptoms and attitudes on health-related quality of life in breast cancer survivors who were premenopausal at the time of diagnosis.

METHODS

A total of 139 women receiving chemotherapy with/without endocrine therapy were assessed with self-report questionnaires of established reliability and validity. Hierarchical regression was conducted to assess the impact of menopausal symptoms and attitudes on quality of life, while controlling for demographic characteristics.

RESULTS

Overall, participants endorsed more than half of 46 symptoms, most at the level of mild symptoms, and most reported a less positive attitude toward menopause. Lower quality of life was significantly predicted by more menopausal symptoms endorsed and more negative attitudes when controlling for demographic factors associated with quality of life (R = 26.1%). Most participants experienced change from premenopause to postmenopause after the completion of adjuvant chemotherapy with or without tamoxifen.

CONCLUSIONS

The results suggest that more menopausal symptoms and negative attitudes toward menopause may affect health-related quality of life considerably in chemotherapy-treated Asian breast cancer survivors.

IMPLICATIONS FOR PRACTICE

Healthcare professionals should develop a better understanding of the effects of menopausal symptoms and attitudes on quality of life by using a culturally relevant perspective based on patients' sociocultural backgrounds. Furthermore, these findings help healthcare professionals communicate with their Asian clients in a more informed way and provide culturally appropriate and individualized care.

Do coping strategies mediate the effects of emotional support on emotional well-being among Spanish-speaking Latina breast cancer survivors?

OBJECTIVE

This study aimed to assess the relationship between emotional social support and emotional well-being among Latina immigrants with breast cancer and test whether two culturally relevant coping strategies, fatalism and acceptance, mediate this relationship.

METHODS

One hundred fifty Spanish-speaking Latinas within 1 year of breast cancer diagnosis participating in a randomized trial of a stress management intervention were assessed in person at baseline and via telephone 6 months later. Survey measures included baseline emotional support, fatalism, and acceptance and emotional well-being 6 months later. Generalized linear models estimated direct effects of emotional support on emotional well-being and indirect effects through fatalism and acceptance.

RESULTS

Mean age was 50.1 (SD = 10.9) years; most women had low education and acculturation levels. Emotional support was negatively associated with fatalism (r = -0.24, p < 0.01) and positively associated with acceptance (r = 0.30, p < 0.001). Emotional support (r = 0.23, p = 0.005) and acceptance (r = 0.28, p = 0.001) were positively associated with emotional well-being, whereas fatalism (r = -0.36, p < 0.0001) was negatively associated with emotional well-being. In multivariable models, emotional support was associated with emotional well-being (b = 0.88, 95% CI: 0.24, 1.52). This direct effect remained significant when additionally controlling for fatalism (b = 0.66, 95% CI: 0.03, 1.30) and acceptance (b = 0.73, 95% CI: 0.09, 1.37) in separate models. There was a significant indirect effect of emotional support on emotional well-being through fatalism (b = 0.21, 95% CI: 0.04, 0.51) as well as a marginally significant effect through acceptance (b = 0.15, 95% CI: 0.001, 0.43).

CONCLUSIONS

Emotional support may increase well-being among Spanish-speaking Latina cancer survivors by reducing cancer fatalism.Copyright © 2015 John Wiley & Sons, Ltd.

A methodological review of the Short Form Health Survey 36 (SF-36) and its derivatives among breast cancer survivors

PURPOSE

A systematic review of the validity, reliability and sensitivity of the Short Form (SF) health survey measures among breast cancer survivors.

METHODS

We searched a number of databases for peer-reviewed papers. The methodological quality of the papers was assessed using the COnsenus-based Standards for the selection of health Measurement INstruments (COSMIN).

RESULTS

The review identified seven papers that assessed the psychometric properties of the SF-36 (n = 5), partial SF-36 (n = 1) and SF-12 (n = 1) among breast cancer survivors. Internal consistency scores for the SF measures ranged from acceptable to good across a range of language and ethnic sub-groups. The SF-36 demonstrated good convergent validity with respective subscales of the Functional Assessment of Cancer Treatment-General scale and two lymphedema-specific measures. Divergent validity between the SF-36 and Lymph-ICF was modest. The SF-36 demonstrated good factor structure in the total breast cancer survivor study samples. However, the factor structure appeared to differ between specific language and ethnic sub-groups. The SF-36 discriminated between survivors who reported or did not report symptoms on the Breast Cancer Prevention Trial Symptom Checklist and SF-36 physical sub-scales, but not mental sub-scales, discriminated between survivors with or without lymphedema. Methodological quality scores varied between and within papers.

CONCLUSION

Short Form measures appear to provide a reliable and valid indication of general health status among breast cancer survivors though the limited data suggests that particular caution is required when interpreting scores provided by non-English language groups. Further research is required to test the sensitivity or responsiveness of the measure.

Occurrence of comorbidities among African-American and Latina breast cancer survivors

BACKGROUND

The co-occurrence of multiple chronic conditions in cancer patients is common and can have negative impact on cancer and cancer survivorship outcomes. This study aimed to document comorbidity occurrence among African-American and Latina (English language preferred (ELP) and Spanish language preferred (SLP)) breast cancer survivors (BCS).

METHODS

Eighty-eight African-American, 95 ELP Latina, and 137 SLP Latina BCS were recruited via case ascertainment from the California Cancer Registry and hospital registries. BCS completed a self-report questionnaire assessing demographic and cancer characteristics, and presence of comorbidities.

RESULTS

Overall, 75% of BCS reported at least one comorbidity with arthritis (37%), high blood pressure (37%), psychological difficulties (29%), and diabetes (19%) being most commonly endorsed. SLP Latinas were more likely to report diabetes (29%), psychological difficulties (42%), and >3 comorbidities (p < 0.05). Latina BCS were twice as likely to report osteoporosis and headaches compared to African-Americans; while one in two African-Americans reported hypertension and arthritis. Older age was correlated with arthritis, diabetes, glaucoma, high blood pressure, and osteoporosis.

CONCLUSIONS

Our findings suggest that investigating the occurrence of comorbidities across ethnic groups may shed some light in understanding cancer survivorship risk for poor health outcomes and health disparities. Having a better grasp of comorbid conditions may aid in more appropriate early assessment, better follow-up care, surveillance, and management of the cancer and the comorbid condition(s).

IMPLICATIONS FOR CANCER SURVIVORS

Integrated control and management of comorbidities among cancer survivors has the potential to improve quality care for the whole person, and increase survival and decrease morbidity.
