The role of social cognitive processing theory and optimism in positive psychosocial and physical behavior change after cancer diagnosis and treatment

Illness Perception and Benefit Finding of Thyroid Cancer Survivors: A Chain Mediating Model of Sense of Coherence and Self-disclosure

BACKGROUND

Benefit finding is gaining attention as a strong predictor of quality of life, but few studies have addressed the mechanisms of its development.

OBJECTIVE

The purpose of this study was to determine the relationship between illness perception and benefit finding in female thyroid cancer survivors and to further elucidate the mechanisms by which illness perception contributes to benefit finding through sense of coherence and self-disclosure.

METHODS

A total of 280 female thyroid cancer survivors completed the questionnaire between January and August 2023. The study investigated participants' baseline information, illness perception, sense of coherence, self-disclosure, and benefit finding. The bootstrap method was used to test the chain mediation effect.

RESULTS

The findings showed that in the chain-mediated model, illness perception negatively predicted sense of coherence (β = -.475, P < .001) and self-disclosure (β = -.335, P < .001). Sense of coherence positively predicted self-disclosure (β = .272, P < .001) and benefit finding (β = .251, P < .001). Self-disclosure positively predicted benefit finding (β = .213, P < .001). The separate mediating roles of sense of coherence and self-disclosure between illness perception and benefit finding were both significant, as were the chained mediating roles of sense of coherence, and self-disclosure.

CONCLUSION

This study provides a theoretical basis for elucidating the mechanisms of benefit finding and provides precise targets for clinical intervention.

IMPLICATIONS FOR PRACTICE

Healthcare professionals can improve mental health outcomes by improving cancer survivors' disease awareness, fostering their sense of coherence, and encouraging moderate self-disclosure to achieve benefit finding.

Virtual Music Therapy versus Virtual Cognitive Behavioral Therapy for Anxiety in Cancer Survivors: Rationale and Protocol for a Comparative Effectiveness Trial (Preprint)

BACKGROUND

Cancer survivors represent one of the fastest growing populations in the United States. Unfortunately, nearly 1 in 3 survivors experience anxiety symptoms as a long-term consequence of cancer and its treatment. Characterized by restlessness, muscle tension, and worry, anxiety worsens the quality of life; impairs daily functioning; and is associated with poor sleep, depressed mood, and fatigue. Although pharmacological treatment options are available, polypharmacy has become a growing concern for cancer survivors. Music therapy (MT) and cognitive behavioral therapy (CBT) are evidence-based, nonpharmacological treatments that have demonstrated effectiveness in treating anxiety symptoms in cancer populations and can be adapted for remote delivery to increase access to mental health treatments. However, the comparative effectiveness of these 2 interventions delivered via telehealth is unknown.

OBJECTIVE

The aims of the Music Therapy Versus Cognitive Behavioral Therapy for Cancer-related Anxiety (MELODY) study are to determine the comparative effectiveness of telehealth-based MT versus telehealth-based CBT for anxiety and comorbid symptoms in cancer survivors and to identify patient-level factors associated with greater anxiety symptom reduction for MT and CBT.

METHODS

The MELODY study is a 2-arm, parallel-group randomized clinical trial that aims to compare the effectiveness of MT versus CBT for anxiety and comorbid symptoms. The trial will enroll 300 English- or Spanish-speaking survivors of any cancer type or stage who have experienced anxiety symptoms for at least 1 month. Participants will receive 7 weekly sessions of MT or CBT delivered remotely via Zoom (Zoom Video Communications, Inc) over 7 weeks. Validated instruments to assess anxiety (primary outcome), comorbid symptoms (fatigue, depression, insomnia, pain, and cognitive dysfunction), and health-related quality of life will be administered at baseline and at weeks 4, 8 (end of treatment), 16, and 26. Semistructured interviews will be conducted at week 8 with a subsample of 60 participants (30 per treatment arm) to understand individual experiences with the treatment sessions and their impact.

RESULTS

The first study participant was enrolled in February 2022. As of January 2023, 151 participants have been enrolled. The trial is expected to be completed by September 2024.

CONCLUSIONS

This study is the first and largest randomized clinical trial to compare the short- and long-term effectiveness of remotely delivered MT and CBT for anxiety in cancer survivors. Limitations include the lack of usual care or placebo control groups and the lack of formal diagnostic assessments for psychiatric disorders among trial participants. The study findings will help guide treatment decisions for 2 evidence-based, scalable, and accessible interventions to promote mental well-being during cancer survivorship.

Personality Traits and Coping Strategies Relevant to Posttraumatic Growth in Patients with Cancer and Survivors: A Systematic Literature Review

The possibility of positive psychological changes after cancer, namely, posttraumatic growth, is a growing field of research. Identifying personality traits and coping strategies related to posttraumatic growth may help find vulnerable individuals as well as promote helpful coping strategies to help more patients make positive changes at an early stage. The aim of this systematic literature review is to provide an overview of the quantitative data on coping strategies and personality traits associated with posttraumatic growth in patients with cancer and cancer survivors as well as the methods used in included studies. A systematic literature search was conducted using five databases (PubMed, PubPsych, PsycInfo, Web of Science, and PSYNDEXplus). The 70 reports of included studies assessed posttraumatic growth using questionnaires in a sample of patients with cancer or survivors. In addition, associations with a personality trait or coping strategy had to be examined cross-sectionally or longitudinally. All 1698 articles were screened for titles and abstracts by two authors, after which disputed articles were reviewed by a third author. Afterwards, articles were screened for full texts. Most studies had a cross-sectional design and used a sample of patients with breast cancer. Coping strategies have been researched more than personality factors. The personality traits of resilience, hardiness, dispositional positive affectivity, and dispositional gratitude seem to be related to posttraumatic growth, while the Big Five personality traits (openness to experience, conscientiousness, extraversion, agreeableness, neuroticism) have been less researched and/or seem to be unrelated. The use of social support, religious coping, positive reframing, and reflection during illness as coping strategies seems to be related to posttraumatic growth. The findings can be used for the development of interventions. Future studies should investigate associations longitudinally.

Psychometric properties of a Chinese version of four-factor colorectal cancer screening belief scale

OBJECTIVE

Screening improves the early diagnosis rate of colorectal cancer (CRC) and effectively reduces its mortality. The four-factor CRC screening belief scale is conducive to understanding the psychometric properties of screening beliefs, but no Chinese version of this scale is available. The purpose of this study was to test the psychometric properties of a Chinese version of the four-factor ​CRC ​screening belief scale in ​patients ​with cancer and their relatives.

METHODS

The four-factor CRC screening belief scale was translated into Chinese based on Brislin's model. A panel review ensured the cultural adaptation and content validity of the scale. The scale was then administered to a convenience sample of 425 Chinese people recruited from July 2019 to June 2021.

RESULTS

Exploratory factor analysis identified the factor structure for the Chinese version of the four-factor CRC screening belief scale, including perceived barriers, perceived benefits, self-efficacy, and optimism. Confirmatory factor analysis showed that the model fits well. The scale-level content validity index was 1.0. The correlation between the Chinese version of the four-factor CRC screening belief scale and the CRC health belief model scale was statistically significant (r = 0.831, P < 0.01). McDonald's omega coefficients for the entire scale were 0.939 and 0.774-0.948 for the four subscales. The translated scale had test-retest reliability of 0.719 and split-half reliability of 0.646.

CONCLUSIONS

The Chinese version of the four-factor CRC screening belief scale showed adequate reliability and validity. The translation and validation of psychosocial assessment tools for CRC screening across languages, cultures, and countries will contribute to further international research collaborations and the improvement of the prospects for the prevention and care of CRC.

Positive behavioral change during the COVID‐19 crisis: The role of optimism and collective resilience

While the issue of behavioral change is of increasing interest to academics and practitioners, an understanding of its drivers remains limited. Consistent with the possibility that destabilizing events can trigger the implementation of beneficial changes in one's life, this research studies the COVID‐19 pandemic and its influence on the adoption of positive habits. More specifically, it focuses on positive health and lifestyle‐related behavioral changes observed within the confined population, as well as the antecedents of such changes. Two surveys conducted 1 month apart in an urban setting severely affected by the pandemic confirm the role of optimism toward the crisis as an antecedent to four changes: slowdown in pace of life, decluttering of personal space, reflection on consumption habits and adoption of healthy behaviors. Collective resilience, social support and anxiety are identified as determinants of optimism. Results suggest an evolution of certain relations including the increase of collective resilience effect on optimism over time.

Psychosocial Determinants of Lifestyle Change after a Cancer Diagnosis: A Systematic Review of the Literature

Simple Summary

Although cancer survivors may experience health benefits from favorable lifestyle changes, many cancer survivors do not adhere to lifestyle recommendations or make favorable lifestyle changes after cancer diagnosis. This systematic review of the literature aimed to provide an overview of the scientific literature on sociodemographic, psychological and social determinants that may facilitate or hamper lifestyle change after the diagnosis cancer. It provides a structured overview of the large variety of determinants of changes in different lifestyle behaviors (physical activity, diet, smoking, alcohol, sun protection, and multiple lifestyle behaviors) derived from the 123 included papers (71 quantitative and 52 qualitative). Findings demonstrate the important role of oncology healthcare professionals in promoting healthy lifestyle changes in cancer survivors and inform researchers and healthcare professionals about the methods and strategies they can use to promote healthy lifestyle changes in cancer survivors.

Abstract

The aim of this study is to provide a systematic overview of the scientific literature on sociodemographic, psychological and social determinants that may facilitate or hamper lifestyle change after the diagnosis cancer. Four databases (PubMed, PsychINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science) were searched for relevant papers up to October 2021. Of the 9586 references yielded by the literature search, 123 papers were included: 71 quantitative and 52 qualitative papers. Findings showed a large variety of determinants influencing lifestyle change after cancer diagnosis, with differences between lifestyle behaviors (physical activity, diet, smoking, alcohol, sun protection, and multiple lifestyle behaviors) and findings from quantitative vs. qualitative studies. Findings demonstrate the important role of oncology healthcare professionals in promoting healthy lifestyle changes in cancer survivors. In addition, findings inform researchers involved in the development of health promotion programs about the methods and strategies they can use to promote healthy lifestyle changes in cancer survivors. Favorable lifestyle changes are expected to have beneficial effects on cancer risk and overall health in cancer survivors.

"Moving Forward": Older Adult Motivations for Group-Based Physical Activity After Cancer Treatment

Background

Engagement in physical activity (PA) post-treatment can improve health outcomes and quality of life among cancer survivors. The purpose of this study is to explore United States (US) older adult cancer survivors’ (OACS) reasons for engaging in group-based PA classes, to identify themes supporting exercise motivations in the context of cancer recovery.

Methods

OACS participating in a fitness program at a large US comprehensive cancer center completed semi-structured interviews. Transcripts were analyzed using modified grounded theory, and demographic data were analyzed descriptively.

Results

Modified grounded theory analysis (n = 25; age M = 70.92, SD = 10.82; 9 cancer types) identified individual rationales for exercise grounded in collective experience. Participants’ internal motivations for PA are shaped by the desire for control over an uncertain future and post-treatment body, obtained by literally “moving forward” post-cancer; this is supported by external motivations for social connections that present a positive model of survivorship, within a setting that instills confidence and safety.

Conclusions

Exercise can be a way for older adults to tap into internal and external motivations that support cancer survivorship. Interventions that make explicit connections between exercise and cancer recovery, facilitate interpersonal interaction, and promote a sense of safety may be the most effective. The concepts identified in this study can inform the development of future interventions to improve long-term behavior change among OACS and evaluate existing PA programs.

Feasibility and effect of a guided self-disclosure intervention designed to facilitate benefit finding in breast cancer patients: A pilot study

PURPOSE

This pilot study aimed to evaluate the feasibility and effect of a guided self-disclosure intervention (GSDI) promoting benefit finding (BF) for breast cancer patients.

METHODS

A total of 40 women with breast cancer were randomized either to a GSDI group, which included a 6-session face-to-face self-disclosure intervention, or to a control group. The Benefit Finding Scale (BFS) was used to measure BF, the Distress Disclosure Index (DDI) was used to measure self-disclosure, and the Impact of Event Scale-Revised (IES-R) was used to measure cognitive reappraisal. The outcomes were evaluated at baseline and the 3rd and 6th months.

RESULTS

The GSDI group had more satisfaction (t = 2.35, P = .02) than the control group and had significant group effects of higher BF (t = 2.214, P = .03) and a lower avoidance of the IES-R (t = -2.353, P = .024) at the 3rd month. There was a significant difference of BF (t = 2.036, P = .049) between the two groups at the 6th month, and other outcomes were not significant (P > .05). Intention-to treat (ITT) analysis showed significant time effects for all outcomes (P < .05); there were slightly significant time × group effects for BF (F = 4.15, P = .052) and disclosure (F = 2.719, P = .090). There were no time × group effects for the other outcomes (all P > .05).

CONCLUSION

This study suggests that the GSDI intervention may be feasible in the clinic and might improve BF for breast cancer patients. However, future research needs to further refine the intervention and expand the sample to carry out a full-scale randomized controlled trial.

The role of meaning in gastric cancer patients: relationships among meaning structures, coping, and psychological well-being

Background and Objectives: Research demonstrates that the experience of cancer invariably violates patients' meaning structures, prompting them to use coping strategies to alleviate stress and enhance well-being. The current study aimed to examine the mediating effects of coping strategies in the relationship between global and situational meaning and psychological well-being in gastric cancer patients. Design and Method: One hundred eighty-seven patients (96 women and 91 men) with gastric cancer completed questionnaires measuring meaning in life, changes of beliefs and goals, coping, and psychological well-being. Participants were between 27 and 82 years of age. They were diagnosed with gastric cancer from 1 to 3.2 years ago. Using Structural Equation Modeling, both the direct and indirect associations between meaning structures, coping, and psychological well-being were examined. Results: Meaning in life exerted significant indirect effects on psychological well-being through three coping strategies: problem-, emotion-, and meaning-focused. The relationship between changes of beliefs and goals and psychological well-being was also mediated by coping. Conclusions: Findings suggest that coping strategies are mediators in the relationship between global and situational meaning and psychological well-being. They also provide empirical evidence that in severe cancer-related stress conditions both meaning structures and coping strategies influence patients' psychological well-being.

The Traumatic Experience of Breast Cancer: Which Factors Can Relate to the Post-traumatic Outcomes?

Background: Post-traumatic growth (PTG) is considered a positive outcome of struggling with a traumatic event, distinct, and opposite from negative outcomes, i.e., psychological distress. The present study aimed to shed light on the relationship between potentially relating factors (i.e., coping strategies, perceived social support, and attachment style) and both positive and negative psychological outcomes. Methods: A total of 123 breast cancer survivors were recruited, who completed a battery of self-report questionnaires, assessing PTG, psychological distress, coping strategies, perceived social support, and attachment style. Three regression analyses were run to evaluate whether relating factors were significant predictors of the positive and negative psychological outcomes. Results: The regression analyses showed that the "Fatalism" coping strategy and perceived social support were two significant predictors of PTG. Instead, the "Helpless-Hopeless" and "Anxious Preoccupation" coping strategies, as well as an insecure attachment style, were significant predictors of depression, while the "Anxious Preoccupation" coping strategy and an insecure attachment style were significant predictors of anxiety. Conclusions: The present findings showed that the factors underlying a positive or negative outcome are different and specific. While perceived social support and a fatalistic attitude seem to play a key role in the positive outcome, dysfunctional coping strategies, together with an insecure attachment style, appear to be related with negative psychological outcome. Considering these factors in clinical practice would help patients to give meaning to their traumatic experience, enhancing psychological growth.

Neurodevelopmental consequences of pediatric cancer and its treatment: applying an early adversity framework to understanding cognitive, behavioral, and emotional outcomes

Today, children are surviving pediatric cancer at unprecedented rates, making it one of modern medicine's true success stories. However, we are increasingly becoming aware of several deleterious effects of cancer and the subsequent "cure" that extend beyond physical sequelae. Indeed, survivors of childhood cancer commonly report cognitive, emotional, and psychological difficulties, including attentional difficulties, anxiety, and posttraumatic stress symptoms (PTSS). Cognitive late- and long-term effects have been largely attributed to neurotoxic effects of cancer treatments (e.g., chemotherapy, cranial irradiation, surgery) on brain development. The role of childhood adversity in pediatric cancer - namely, the presence of a life-threatening disease and endurance of invasive medical procedures - has been largely ignored in the existing neuroscientific literature, despite compelling research by our group and others showing that exposure to more commonly studied adverse childhood experiences (i.e., domestic and community violence, physical, sexual, and emotional abuse) strongly imprints on neural development. While these adverse childhood experiences are different in many ways from the experience of childhood cancer (e.g., context, nature, source), they do share a common element of exposure to threat (i.e., threat to life or physical integrity). Therefore, we argue that the double hit of early threat and cancer treatments likely alters neural development, and ultimately, cognitive, behavioral, and emotional outcomes. In this paper, we (1) review the existing neuroimaging research on child, adolescent, and adult survivors of childhood cancer, (2) summarize gaps in our current understanding, (3) propose a novel neurobiological framework that characterizes childhood cancer as a type of childhood adversity, particularly a form of early threat, focusing on development of the hippocampus and the salience and emotion network (SEN), and (4) outline future directions for research.

Childhood maltreatment, psychological resources, and depressive symptoms in women with breast cancer

Childhood maltreatment is associated with elevated risk for depression across the human lifespan. Identifying the pathways through which childhood maltreatment relates to depressive symptoms may elucidate intervention targets that have the potential to reduce the lifelong negative health sequelae of maltreatment exposure. In this cross-sectional study, 271 women with early-stage breast cancer were assessed after their diagnosis but before the start of adjuvant treatment (chemotherapy, radiation, endocrine therapy). Participants completed measures of childhood maltreatment exposure, psychological resources (optimism, mastery, self-esteem, mindfulness), and depressive symptoms. Using multiple mediation analyses, we examined which psychological resources uniquely mediated the relationship between childhood maltreatment and depressive symptoms. Exposure to maltreatment during childhood was robustly associated with lower psychological resources and elevated depressive symptoms. Further, lower optimism and mindfulness mediated the association between childhood maltreatment and elevated depressive symptoms. These results support existing theory that childhood maltreatment is associated with lower psychological resources, which partially explains elevated depressive symptoms in a sample of women facing breast cancer diagnosis and treatment. These findings warrant replication in populations facing other major life events and highlight the need for additional studies examining childhood maltreatment as a moderator of treatment outcomes.

Post-traumatic stress disorder and cancer

Being diagnosed with and treated for cancer is highly stressful and potentially traumatic. An extensive literature has evaluated the prevalence, predictors, and correlates of cancer-related post-traumatic stress disorder (PTSD) symptoms and diagnoses. In this qualitative review of cancer-related PTSD literature, we highlight conceptual, methodological, and diagnostic issues, and identify clinical implications and areas for future research. Cancer-related PTSD has been documented in a minority of patients with cancer and their family members, is positively associated with other indices of distress and reduced quality of life, and has several correlates and risk factors (eg, prior trauma history, pre-existing psychiatric conditions, poor social support). The literature on treatment of cancer-related PTSD is sparse. Existing literature on cancer-related PTSD has used DSM-IV-TR diagnostic criteria; the revised DSM-5 PTSD criteria have important implications for the assessment of cancer-related distress. Application of PTSD diagnosis to patients with cancer has been critiqued on conceptual and methodological grounds, and important differential diagnosis considerations should be taken into account. Psychosocial assessment of patients with cancer should include careful evaluation of pre-cancer diagnosis trauma and psychiatric history, and diagnostic interviewing should consider concurrent conditions (eg, adjustment disorder). Treatment of cancer-related PTSD should be approached with caution and be informed by existing evidence-based approaches for traumatic stress.

Objectively Assessed Exercise Behavior in Chinese Patients with Early-Stage Cancer: A Predictor of Perceived Benefits, Communication with Doctors, Medical Coping Modes, Depression and Quality of Life

This study sought to identify factors associated with objectively assessed exercise behavior in Chinese patients with early-stage cancer. Three hundred and fifty one cancer patients were recruited from the Affiliated Jiangyin Hospital of Southeast University Medical College and the Nantong Tumor Hospital. One-way ANOVA, Pearson Chi-square tests and regression analysis were employed to identify the correlations between physical exercise and the measured factors. The results showed that occupation type (χ2 = 14.065; p = 0.029), monthly individual monthly income level (χ2 = 24.795; p = 0.003), BMI (χ2 = 15.709; p = 0.015) and diagnosis (χ2 = 42.442; p < 0.000) were significantly correlated with the subjects self-reported exercise with different frequency per week. Differences in the frequency of exercise were associated with different degrees of reported Benefit Finding (BF) (F = 24.651; p < 0.000), communication with doctors (F = 15.285; p < 0.000), medical coping modes (F = 45.912; p < 0.000), social support (F = 2.938; p = 0.030), depression (F = 6.017; p < 0.000), and quality of life (F = 12.288; p < 0.000). Multiple regression analysis showed that 1.6%-6.4% of the variance in five variables, excluding social support and optimism could be explained by exercise. Our results indicated that benefit finding, medical coping modes, communication with doctors, social support, depression and quality of life were significantly correlated with exercise. The variance in several psychosocial factors (benefit finding, medical coping modes, the communication with doctors, depression and quality of life) could be explained by exercise. Psychosocial factors should be addressed and examined over time when evaluating the effect of physical exercise that is prescribed as a clinically relevant treatment.

Health Behaviors Among Breast Cancer Patients and Survivors

BACKGROUND

With improved treatments, the survival rate for breast cancer patients is increasing. With the improvements in quantity of life, research in the field of cancer survivorship has turned its attention to psychosocial functioning and health behaviors.

OBJECTIVES

The purpose of this study was to examine how those currently under treatment and those completing treatment engaged in health behaviors (ie, diet, vitamin use, exercise, and cancer screening) and if psychosocial predictors, guided by the Self-regulation Model, also play a role.

METHODS

Using the Self-regulation Model, the current survey and medical record review examined health behaviors (diet, vitamin use, exercise, cancer screening) in individuals in active treatment for breast cancer and in those completing treatment (n = 141).

RESULTS

Regression models revealed that those in active treatment had less healthy food consumption, vitamin use, and clinical examinations than did treatment completers. Greater perceived treatment efficacy was associated with diet and vitamin use but not exercise or cancer screening. Greater perceived risk of recurrence was associated with less exercise. Greater distress was associated with greater mammography use. Those from metro areas had greater healthy food consumption.

RESULTS

Qualitative data indicated that chemotherapy interfered with health behaviors for those in active treatment; treatment completers wished to have a healthier lifestyle.

CONCLUSION

Cancer treatment interferes with health behaviors, and these health behaviors might help individuals manage their cancer treatment more effectively.

IMPLICATIONS FOR PRACTICE

Those currently undergoing treatment desire assistance with a healthier lifestyle, and relevant clinical interventions should stress treatment efficacy.

Optimism and Spontaneous Self-affirmation are Associated with Lower Likelihood of Cognitive Impairment and Greater Positive Affect among Cancer Survivors

BACKGROUND

Optimism and self-affirmation promote adaptive coping, goal achievement, and better health.

PURPOSE

The aim of this study is to examine the associations of optimism and spontaneous self-affirmation (SSA) with physical, mental, and cognitive health and information seeking among cancer survivors.

METHODS

Cancer survivors (n = 326) completed the Health Information National Trends Survey 2013, a national survey of US adults. Participants reported optimism, SSA, cognitive and physical impairment, affect, health status, and information seeking.

RESULTS

Participants higher in optimism reported better health on nearly all indices examined, even when controlling for SSA. Participants higher in SSA reported lower likelihood of cognitive impairment, greater happiness and hopefulness, and greater likelihood of cancer information seeking. SSA remained significantly associated with greater hopefulness and cancer information seeking when controlling for optimism.

CONCLUSIONS

Optimism and SSA may be associated with beneficial health-related outcomes among cancer survivors. Given the demonstrated malleability of self-affirmation, these findings represent important avenues for future research.

Stressful Life Events and Predictors of Post-traumatic Growth among High-Risk Early Emerging Adults

Stressful life events (SLEs) may elicit positive psychosocial change among youth, referred to as Post-traumatic Growth (PTG). We assessed types of SLEs experienced, degree to which participants reported PTG, and variables predicting PTG across 24 months among a sample of high risk, ethnically diverse early emerging adults. Participants were recruited from alternative high schools (n = 564; mean age=16.8; 65% Hispanic). Multi-level regression models were constructed to examine the impact of environmental (SLE quantity, severity) and personal factors (hedonic ability, perceived stress, developmental stage, future time orientation) on a composite score of PTG. The majority of participants reported positive changes resulted from their most life-altering SLE of the past two years. Predictors of PTG included fewer SLEs, less general stress, having a future time perspective, and greater identification with the developmental stage of Emerging Adulthood. Findings suggest intervention targets to foster positive adaptation among early emerging adults who experience frequent SLEs.

Resilience and psychosocial adjustment in digestive system cancer

The study aims to investigate the contributions of resilience, affective reactions and post traumatic growth (PTG) to psychosocial adjustment and behavioral changes among digestive system cancer patients in Israel. A sample of 200 participants, 57.5 % men (from the 46 to 70-year age range), 1-4 years following diagnosis, completed an inventory assessing demographic and medical information, resilience, current positive affect (PA) and negative affect (NA), PTG, psychosocial adjustment and retrospective report of behavioral changes following cancer treatment. Resilience, PA and NA, and PTG were related to adjustment and/or reported behavioral changes, and PA, NA and PTG mediated some of the effects of resilience on adjustment and/or reported behavioral changes. The data underline the importance of resilience, affect, and PTG in the adjustment of digestive system cancer patients. Future studies are needed to better understand the associations of resilience with psychosocial adjustment and behavioral changes. This knowledge may help improve cancer survivors' adjustment.

High-level construal benefits, meaning making, and posttraumatic growth in cancer patients

Objective:

The present study sought to explore the role of meaning making and high-level construal in the relationship between meaning discrepancy and posttraumatic growth among Chinese cancer patients.

Method:

The participants were 193 individuals diagnosed with cancer. Meaning discrepancy, meaning making, high-level construal in meaning making, and posttraumatic growth were measured. Bootstrapping and structural equation modeling were performed to test the mediation effects of high-level construal on the meaning-making process.

Results:

Mediation analysis revealed that perceived discrepancies were associated with individuals' meaning-making efforts. Meaning-making efforts prompted participants to adopt a high-level construal orientation, which in turn enhanced posttraumatic growth.

Significance of results:

Our study empirically tested construal level theory in a population suffering from severe chronic trauma. The results demonstrate the important role of high-level construal in the meaning-making process of cancer patients, suggesting a specific effective strategy to foster posttraumatic growth. It seems encouraging to indicate that adopting such high-level construal may be included as part of psychological interventions for cancer patients.

Correspondence of physical activity and fruit/vegetable consumption among prostate cancer survivors and their spouses

A healthy diet and physical activity are recommended for prostate cancer survivors. Interdependence theory suggests that the spousal relationship influences those health behaviours and the degree of correspondence may be an indicator of this influence. This study evaluated the correspondence between prostate cancer survivors and spouses regarding physical activity and fruit/vegetable consumption. Baseline data from an ongoing randomised control trial were utilised. Men who had been treated for prostate cancer within the past year and their partners (N = 132 couples) completed self-report measures of physical activity, fruit/vegetable consumption, relationship satisfaction and support for partner's healthy diet and physical activity. Couples reported similar fruit/vegetable consumption and physical activity as indicated by high levels of correspondence. Greater fruit/vegetable correspondence was related to higher relationship satisfaction (F = 4.14, P = 0.018) and greater patient (F = 13.29, P < 0.001) and spouse-rated support (F = 7.2, P < 0.001). Greater physical activity correspondence was related to greater patient (F = 3.57, P = 0.028) and spouse-rated support (F = 4.59, P = 0.031). Prostate cancer survivors and spouses may influence each other's diet and exercise behaviours. Couple-based interventions may promote healthy behaviours among this population.

Correlates of positive health behaviors in cancer survivors: results from the 2010 LIVESTRONG survey

Positive health-promoting behaviors, including lifestyle factors (e.g., physical activity) and appropriate health service utilization (e.g., screening for secondary cancers), can minimize the health risks and challenges facing cancer survivors. The goal of this article is to examine factors associated with positive health behaviors in 2,615 posttreatment cancer survivors who completed the 2010 LIVESTRONG survey. Multivariate logistic regression was used to model odds of reporting each of six positive health behaviors "as a result of your experience with cancer": three "healthy lifestyle" behaviors and three "health care utilization" behaviors. In fully adjusted models, factors associated with greater likelihood of engaging in positive lifestyle behaviors (e.g., physical activity, changing diet) included sociodemographic factors, greater knowledge about how to reduce cancer risk; and reporting more psychological benefits due to cancer (ps <.01). Factors associated with greater likelihood of attending medical appointments and obtaining recommended cancer screenings included older age, better patient-provider communication, greater knowledge about how to reduce cancer risk, and more psychological benefits of cancer (ps <.01). Results suggest that knowledge about how to prevent cancer and benefit finding after cancer are related to positive health behaviors broadly, whereas better patient-provider communication is associated with positive cancer screening and health care utilization but not healthy lifestyle behaviors. Clinical interventions targeting these modifiable factors could maximize positive health behavior changes among cancer survivors, affecting risk for cancer recurrence as well as overall health and well-being.

A meta-analysis of the relationship between social constraints and distress in cancer patients

Social constraints on cancer-related disclosure have been associated with increased distress among cancer patients. The goals of this meta-analysis were: (1) to quantify the average strength of the relationships between social constraints and general and cancer-specific distress in cancer patients; and (2) to examine potential moderators of these relationships. A literature search was conducted using electronic databases, and 30 studies met inclusion criteria. Moderate, significant relationships were found between social constraints and both general distress (r = 0.37, 95 % CI 0.31-0.43) and cancer-specific distress (r = 0.37, 95 % CI 0.31-0.44). The relationship between social constraints and cancer-specific distress was stronger for studies of patients who, on average, had been diagnosed more recently. Relationships between social constraints and both general and cancer-specific distress did not vary by age or gender. Findings suggest that social constraints may be important to target in interventions to reduce distress in cancer patients, especially those who have been recently diagnosed.

Cancer-Related Disclosure Among Adolescent and Young Adult Cancer Survivors: A Qualitative Study

Purpose: Adolescents and young adults (AYAs) employ self-disclosure in normative social interactions and in promoting identity development. Disclosure is associated with numerous psychological and physical benefits. Little research has examined how AYA cancer survivors diagnosed during adolescence disclose their cancer history. Methods: Using a qualitative design, this study explored cancer-related disclosures among survivors (N=26) 16-24 years old at study (M=19.6 years), 14-18 years old at diagnosis (M=15.6 years), and currently at least 6 months post-treatment (M=3.2 years). Semi-structured interview guides were developed and used. Disclosure-related topics included survivorship communications and others' responses to AYAs' disclosure of their cancer experiences. Results: Grounded theory and thematic content analysis guided analyses, with an inductive data-driven approach. Three themes and eight subthemes emerged: "it depends" decision-making processes (don't ask/don't tell, shared experience, relationship potential), perceptions of others' responses (perceived apprehension, positive responses), and methods of disclosure (verbal, written, behavioral). No thematic differences were found by gender or age, although females reported greater frequency of disclosures. Conclusion: Disclosure emerged as a nuanced and complex process. "It depends" decision-making processes were most frequently endorsed, consistent with developmental complexities of this age group. This reflects social and psychological changes and highlights unique challenges for AYA survivors. This also reflects the importance of peers and social interactions as variables that influence disclosure. In the context of AYA cancer survivorship, understanding ways in which disclosure may bolster or hinder social support can assist survivors, clinicians, and families navigate survivorship. Implications for future research are discussed.

The influence of coping response and health-related quality of life on perceived social support during cancer treatment

OBJECTIVE

In the biopsychosocial approach, perceived social support has served as a protective factor for psychological adjustment to cancer. This study aimed to determine the influence of different coping responses and health-related quality of life (HRQoL) domains on perceived social support during cancer treatment.

METHOD

A cross-sectional analysis was carried out in a sample of 757 cancer outpatients. The Medical Outcomes Study Social Support Survey (MOS-SSS) was employed to assess perceived social support. The Mental Adjustment to Cancer (MAC) Scale measured coping response, and HRQoL was tested with the Medical Outcomes Study Short Form-36 (SF-36). Multivariate analyses were carried out to examine the extent to which coping and HRQoL were associated with perceived social support.

RESULTS

Coping response explained only 2% of the variance in perceived social support, but Hopelessness had a significant influence on perceived social support (p ≤ 0.01). HRQoL, physical, and mental domains made a significant contribution toward perceived social support, accounting for around 10% of total variance. More than coping response, HRQoL's physical and mental domains had an important influence on perceived social support during cancer treatment.

SIGNIFICANCE OF RESULTS

The findings of the current study report the importance of HRQoL domains in predicting perceived social support during cancer treatment, emphasizing the holistic and multidisciplinary approach to facilitate adjustment to cancer.

The effects of stress on physical activity and exercise

BACKGROUND

Psychological stress and physical activity (PA) are believed to be reciprocally related; however, most research examining the relationship between these constructs is devoted to the study of exercise and/or PA as an instrument to mitigate distress.

OBJECTIVE

The aim of this paper was to review the literature investigating the influence of stress on indicators of PA and exercise.

METHODS

A systematic search of Web of Science, PubMed, and SPORTDiscus was employed to find all relevant studies focusing on human participants. Search terms included "stress", "exercise", and "physical activity". A rating scale (0-9) modified for this study was utilized to assess the quality of all studies with multiple time points.

RESULTS

The literature search found 168 studies that examined the influence of stress on PA. Studies varied widely in their theoretical orientation and included perceived stress, distress, life events, job strain, role strain, and work-family conflict but not lifetime cumulative adversity. To more clearly address the question, prospective studies (n = 55) were considered for further review, the majority of which indicated that psychological stress predicts less PA (behavioral inhibition) and/or exercise or more sedentary behavior (76.4 %). Both objective (i.e., life events) and subjective (i.e., distress) measures of stress related to reduced PA. Prospective studies investigating the effects of objective markers of stress nearly all agreed (six of seven studies) that stress has a negative effect on PA. This was true for research examining (a) PA at periods of objectively varying levels of stress (i.e., final examinations vs. a control time point) and (b) chronically stressed populations (e.g., caregivers, parents of children with a cancer diagnosis) that were less likely to be active than controls over time. Studies examining older adults (>50 years), cohorts with both men and women, and larger sample sizes (n > 100) were more likely to show an inverse association. 85.7 % of higher-quality prospective research (≥ 7 on a 9-point scale) showed the same trend. Interestingly, some prospective studies (18.2 %) report evidence that PA was positively impacted by stress (behavioral activation). This should not be surprising as some individuals utilize exercise to cope with stress. Several other factors may moderate stress and PA relationships, such as stages of change for exercise. Habitually active individuals exercise more in the face of stress, and those in beginning stages exercise less. Consequently, stress may have a differential impact on exercise adoption, maintenance, and relapse. Preliminary evidence suggests that combining stress management programming with exercise interventions may allay stress-related reductions in PA, though rigorous testing of these techniques has yet to be produced.

CONCLUSIONS

Overall, the majority of the literature finds that the experience of stress impairs efforts to be physically active. Future work should center on the development of a theory explaining the mechanisms underlying the multifarious influences of stress on PA behaviors.

Theory-and evidence-based development and process evaluation of the Move More for Life program: a tailored-print intervention designed to promote physical activity among post-treatment breast cancer survivors

Objective

Several physical activity interventions have been effective in improving the health outcomes of breast cancer survivors. However, few interventions have provided detailed descriptions regarding how such interventions work. To develop evidence-based practice in this field, detailed descriptions of intervention development and delivery is needed. This paper aims to (1) describe the theory-and evidence-based development of the Move More for Life program, a physical activity program for breast cancer survivors; and (2) serve as an exemplar for theory-based applied research.

Method

The program-planning model outlined by Kreuter and colleagues was used to develop the computer-tailored intervention.

Results

The tailoring guide developed by Kreuter and colleagues served as a useful program planning tool in terms of integrating theory and evidence-based best practice into intervention strategies. Overall, participants rated the intervention positively, with the majority reporting that the tailored materials caught their attention, were personally relevant to them, and were useful for helping them to change their behaviour. However, there was considerable room for improvement.

Conclusion

The Move More for Life program is an example of a theory-based, low-cost and potentially sustainable strategy to physical activity promotion and may stand as an exemplar for Social Cognitive Theory-based applied research. By providing a detailed description of the development of the Move More for Life program, a critical evaluation of the working mechanisms of the intervention is possible, and will guide researchers in the replication or adaption and re-application of the specified techniques. This has potential implications for researchers examining physical activity promotion among cancer survivors and for researchers exploring distance-based physical activity promotion techniques among other populations.

Post-traumatic growth among an ethnically diverse sample of adolescent and young adult cancer survivors

OBJECTIVE

Although some survivors of childhood cancer report significant psychosocial distress, many also report having derived benefits, or post-traumatic growth (PTG), from their cancer experience. This study examines PTG and its correlates among an ethnically diverse sample of adolescent/young adult (AYA) cancer survivors who have recently completed treatment.

METHODS

Survivors of childhood cancer (n = 94; 47% Hispanic), ages 11-21 and within 6 months of completing cancer therapy, were recruited from three pediatric cancer centers. Participants completed a structured interview that assessed demographics, PTG, post-traumatic stress symptoms, health-related quality of life, optimism, and depressive symptoms. Diagnosis/treatment information was collected from each patient's medical record. Multiple regression analyses were used to identify significant correlates of PTG.

RESULTS

The majority of survivors reported positive growth. PTG was positively associated with psychosocial functioning and post-traumatic stress symptoms and inversely associated with physical functioning and depressive symptoms. PTG was significantly lower among survivors of bone tumors (vs. survivors of other cancers) and Hispanic survivors who primarily spoke English at home (vs. Hispanics who primarily spoke Spanish at home and non-Hispanics). PTG was not significantly related to age, sex, optimism, cancer treatment modality, duration of treatment, or treatment intensity.

CONCLUSIONS

The AYA survivors commonly reported PTG in the immediate aftermath of cancer treatment. Findings regarding PTG among more acculturated Hispanic and bone tumor AYA survivors may help to inform risk-adapted clinical interventions, among those transitioning from active treatment to post-treatment surveillance, to mitigate negative long-term sequelae and enhance positive psychosocial adaptation from the cancer diagnosis and treatment.

"It's up to you and God": understanding health behavior change in older African American survivors of colorectal cancer

This study investigated the beliefs and attitudes of older African American colorectal cancer (CRC) survivors that may influence health behavior changes after treatment. Drawing from existing theories of health behavior change and cultural beliefs about health, a semi-structured interview guide was developed to elicit survivors' perspectives. Qualitative focus groups and interviews were conducted with 17 survivors identified through the Detroit Surveillance Epidemiology and End Results registry. Using verbatim transcripts from the sessions and NVivo software, thematic analysis was conducted to analyze patterns of responses. Transcripts were coded for seven categories (health behaviors, who/what motivates change, self-efficacy, fatalism, religion/spirituality, beliefs about cancer, race/ethnicity). Five themes emerged from the data (personal responsibility, resilience, desire for information, intentions to change, beliefs in divine control). Findings support the relevance of existing theories of health behavior change to older African American CRC survivors. Cultural considerations are suggested to improve interventions seeking to maximize changes in diet and exercise among this group of survivors.

A Social Cognitive Perspective on Coping With Cancer

With increases in the number of cancer survivors, many persons now experience cancer as a chronic disease followed by adaptation to a new reality of what is normal in their lives. In response, cancer survivorship researchers have begun attending to the multidimensional needs of survivors, including the need to promote optimal psychological adaptation and health. Theoretical models of well-being that account for the complexity of survivorship issues are needed. We present a social cognitive model of restorative well-being as a framework for reviewing recent research on coping with early stage adult cancer (i.e., stages I and II) and optimizing post-treatment adjustment. We focus on research on cancer-related coping strategies, efficacy beliefs, personality traits, and environmental supports, which have been linked to adjustment outcomes and which may inform psychosocial interventions. By grounding this research in a theoretical base, we highlight the potential for counseling psychologists’ contributions to cancer survivorship research.

Treatment-related and psychosocial variables in explaining physical activity in women three weeks to six months post-treatment of breast cancer

OBJECTIVE

This study examined treatment-related and psychosocial variables in explaining total and leisure time physical activity in breast cancer survivors three weeks to six months post-treatment.

METHODS

A questionnaire was used to measure total and leisure time physical activity and relevant determinants among 464 breast cancer survivors (aged 18-65 years).

RESULTS

Personal control was an important overall determinant in explaining physical activity in breast cancer survivors. The impact of treatment-related variables and psychological functioning depended on the working status of the women. Fatigue and poor body image prevented non-working women from being sufficiently physically active. In working women, chemotherapy and arm problems negatively influenced physical activity, whereas therapy side-effects (headaches, hot flashes, feeling unwell) and poor body image positively influenced physical activity. Social support and coping strategies could not explain post-treatment physical activity levels.

CONCLUSION

Personal control, treatment-related variables and psychological functioning influenced physical activity after cancer treatment. Relations depended on the working status of the women.

PRACTICE IMPLICATIONS

Incorporating self-control methods in physical activity interventions after breast cancer could be helpful. Furthermore, interventions should be tailored to the experienced symptoms (fatigue, arm-problems, body image) and working status of women.

Social support and physical activity engagement by cancer survivors

Less than 20% of adult cancer survivors participate in physical activity and, as a result of such inactivity, cancer survivors are at increased risk for developing chronic diseases. Studies have linked social support as a predictor of physical activity participation in healthy adults. The primary goal of this systematic review is to examine the relationship between social support and physical activity engagement in adult cancer survivors and determine whether additional research is needed in this area. Several databases were searched and articles were systematically extracted according to the inclusion and exclusion criteria. That search yielded 69 articles, 22 of which were identified and included in this review. Fifty percent of the studies showed a significant relationship between social support and physical activity engagement; however, 59% of the participants were breast cancer survivors. The findings suggest that additional research is needed to develop social support strategies that will increase physical activity engagement in adult survivors of cancers other than breast cancer.

Fertility treatment response: is it better to be more optimistic or less pessimistic?

OBJECTIVE

To evaluate the prospective relation between dispositional traits of optimism and pessimism and in vitro fertilization (IVF) treatment failure among women seeking medical intervention for infertility.

METHODS

Among 198 women (aged 24-45 years, mean [standard deviation] = 35.1 [4.1] years; white, 77%), the outcome of each participant's first IVF treatment cycle was examined. Treatment outcome was classified as being successful (versus failed) if the woman either delivered a baby or was pregnant because of the cycle by the end of the 18-month study period. At baseline, optimism and pessimism were measured as a single bipolar dimension and as separate unipolar dimensions according to the Life Orientation Test total score and the optimism and pessimism subscale scores, respectively.

RESULTS

Optimism/pessimism, measured as a single bipolar dimension, predicted IVF treatment failure initially (B = -0.09, p = .02, odds ratio [OR] = 0.917, 95% confidence interval [CI] = 0.851-0.988), but this association attenuated after statistical control for trait negative affect (B = -0.06, p = .13, OR = 0.938, 95% CI = 0.863-1.020). When examined as separate unipolar dimensions, pessimism (B = 0.14, p = .04, OR = 1.146, 95% CI = 1.008-1.303), not optimism (B = -0.09, p = .12, OR = 0.912, 95% CI = 0.813-1.023), predicted IVF treatment failure independently of risk factors for poor IVF treatment response and trait negative affect.

CONCLUSIONS

Being pessimistic may be a risk factor for IVF treatment failure. Future research should attempt to delineate the biological and behavioral mechanisms by which pessimism may negatively affect treatment outcomes.

The contribution of general and cancer-related variables in explaining physical activity in a breast cancer population 3 weeks to 6 months post-treatment

OBJECTIVE

Physical activity determinants are subject to change when confronted with the diagnosis of 'cancer' and new cancer-related determinants appear. The aim of the present study is to compare the contribution of cancer-related determinants with more general ones in explaining physical activity 3 weeks to 6 months post-treatment.

METHODS

A theory-based and validated questionnaire was used to identify physical activity levels (total and domain-specific) and associated determinants among 464 breast cancer survivors (aged 18 to 65 years) 3 weeks to 6 months post-treatment.

RESULTS

Descriptive analyses showed higher scores for general determinants in comparison with cancer-related determinants. Nevertheless, regression analyses showed that both general and cancer-related determinants explained total and domain-specific physical activity. Self-efficacy, enjoyment, social support, lack of time and lack of company were important general determinants. The perception of returning to normal life, cancer-related barriers (fatigue, lack of energy and physical side effects) and self-efficacy in overcoming these barriers were important cancer-related determinants. Although results differed according to the women's working status and the physical activity domain, general self-efficacy explained most physical activity types in both groups.

CONCLUSION

Comparable with the general population, enhancing breast cancer survivors' self-efficacy in being sufficiently physically active seems to be important in physical activity interventions post-treatment. However, interventions should be tailored to the experienced symptoms and working status of the women.

Posttraumatic growth in breast cancer survivors: a comparison of volunteers and non-volunteers

BACKGROUND

The need to understand posttraumatic growth (PTG) in relation to actual changes in an individual's life has recently been raised. However, the relationship of volunteering, health, and PTG has not yet been assessed.

AIMS

To assess the relationship of volunteer work, health, and PTG, and to assess whether cognitive and emotional processing, emotional expressing, and social support differ in volunteer and non-volunteer breast cancer survivors.

METHODS

Participants were 84 breast cancer survivors who had volunteered to work with newly diagnosed breast cancer patients and 40 breast cancer survivors who did not participate in any volunteer work. Participants completed the PTG inventory, the emotional expression and processing scale, the cognitive processing scale, and the multidimensional scale of perceived social support.

RESULTS

Participants in both groups reported similar and relatively high levels of PTG (M = 70.22, SD = 17.38 in a possible range of 0-105). In the volunteer group, PTG levels were not related to self-reported health (r = 0.07, p>0.05), while in the non-volunteer group a high and significant correlation between self-reported health and PTG (r = 0.46, p<0.001), and a significant effect of group × self-reported health on PTG levels, were found. The study variables accounted for 31% of PTG variance, with cognitive and emotional processing and the interaction of group × health being significant predictors.

CONCLUSIONS

Although volunteers did not differ from non-volunteers in PTG levels, higher PTG was related to better health in the non-volunteers group only. These findings point to the complexity of PTG structure and its multifaceted relation to behavior.

Of babies and bathwater: a reply to Coyne and Tennen's views on positive psychology and health

PURPOSE

We disagree with several conclusions reached by Coyne and Tennen, as well as their interpretation of specific findings.

RESULTS

First, we dispute that researchers have advanced the claim that positive thinking can cure disease. Second, we question their exclusive focus on cancer-related mortality, when strong cumulative evidence suggests that optimism is related to positive health outcomes for other major diseases, and that psychosocial interventions may improve other important cancer outcomes, such as reduced pain and increased quality of life. Third, we disagree sharply with their assessment of the literature on posttraumatic growth and the implications of the research they cite.

CONCLUSION

It is premature to abandon efforts to understand and promote positive phenomena among people with various life-threatening illnesses. Instead, well-validated measures of positive phenomena should become routinely incorporated into a broader array of health psychology studies to provide a rigorous test of their role in human health and adaptation to disease.

The combined contribution of social support and coping strategies in predicting post-traumatic growth: a longitudinal study on cancer patients

OBJECTIVES

The aim of this study is to investigate the role of social support and coping strategies in enhancing post-traumatic growth (PTG) in cancer patients. The study focused on both avoidance and approaching coping and on four distinct types of social support: (a) perceived availability, (b) actual received, (c) satisfaction with received support, and (d) the competence of caregiver to satisfy the patient's basic psychological needs of autonomy, competence, and relatedness.

METHODS

A longitudinal study was conducted with a group of 41 cancer patients currently in the treatment and management phase of their illness. Data were collected by means of a written questionnaire, at two time points (T1 and T2) that were 6 months apart. Social support was assessed using the Interpersonal Support Evaluation List and the Need Satisfaction in Relationship Scale. Coping strategies were assessed using the Brief COPE questionnaire. Social support and coping strategies were assessed only at T1. PTG was assessed using the Post-Traumatic Growth Inventory at T1 and T2. Correlation and regression analyses were used to examine the association between social support and coping strategies with short-term reports of post-traumatic growth.

RESULTS

Regression analyses showed that autonomy-supportive caregivers and a problem-focused strategy of coping significantly predicted greater PTG at T2.

CONCLUSIONS

This study contributes to a deeper understanding of the type of social support that may specifically aid cancer patients in experiencing PTG. Furthermore, findings confirm the important role of problem-focused coping strategies in growing psychologically.

Long term posttraumatic growth after breast cancer: prevalence, predictors and relationships with psychological health

This study evaluated the prevalence and predictors of long term posttraumatic growth (PTG) after breast cancer, and relationships of PTG with psychological health in a random sample of 307 currently disease-free women 5-15 years after diagnosis. This cross-sectional study reveals long term posttraumatic growth scores comparable to those found in shorter term studies. Prevalence of a better appreciation of life is especially noteworthy. With the exception of perceived current sequelae of disease associated in a somewhat curvilinear fashion with PTG, demographic and medical variables are poor predictors of the issue. On the contrary, dispositional positive affectivity and adaptative coping of positive, active, relational, religious and to some extent denial coping have a strong effect on growth. Finally, PTG is slightly associated with mental quality of life and happiness. Findings are discussed in the light of posttraumatic growth theory.

The moderating role of different sources of perceived social support on the dispositional optimism-- posttraumatic growth relationship in postoperative breast cancer patients

The purpose of this study was to investigate the dispositional optimism-posttraumatic growth (PTG) relationship in postoperative breast cancer patients and to examine if perceived social support moderates this relationship. The study was conducted with 104 women undergoing postoperative chemotherapy treatment or coming to the hospital for their routine controls. Hierarchical multiple regression analyses indicated that breast cancer survivors high on dispositional optimism and perceived social support, are more likely to develop PTG. Among the different sources of social support, only social support perceived from a private person moderated the dispositional optimism-PTG relationship. Strengths, limitations and possible implications of the findings are discussed.

Relationships among optimism, well-being, self-transcendence, coping, and social support in women during treatment for breast cancer

OBJECTIVE

The impact of diagnosis and treatment for breast cancer, stressors that affect emotional well-being, is influenced by several psychosocial factors and the relationships among them. The purpose of this study was to investigate the relationship between optimism and emotional well-being (EWB) and the individual and combined mediation of this relationship by perceived social support (SS), problem focused coping (PFC), and self-transcendence in women with breast cancer during radiation therapy.

METHODS

Ninety-three women receiving radiation treatment for breast cancer completed questionnaires that measured EWB, optimism, SS, PFC, and self-transcendence.

RESULTS

Correlational and multiple regression analysis revealed that optimism was positively related to EWB. Of the three mediators, self-transcendence alone was found to partially mediate the relationship between optimism and EWB. The relationship between optimism and PFC was not significant. Optimism was related to SS, but its indirect effect on EWB through SS did not reach significance.

CONCLUSIONS AND IMPLICATIONS

During breast cancer treatment, the positive effects of optimism on EWB are partially mediated by a woman's level of self-transcendence. Brief screening of women's optimism may help identify women at risk for psychological distress. Early detection and interventions to promote psychological adjustment throughout the cancer trajectory (e.g. enhancing self-transcendence) should receive attention in future research.

Personality predicts prostate cancer treatment decision-making difficulty and satisfaction

OBJECTIVE

Prostate cancer (PCa) patients often must decide between several treatment modalities considered equally efficacious, but associated with different benefits and side-effects. For some, the decision-making process can be difficult, but little is known about patient characteristics and cognitive processes that might influence the difficulty of such decisions. This study investigated the roles of dispositional optimism and self-efficacy in PCa treatment decision-making difficulty and satisfaction.

METHODS

One hundred and twenty-five patients with clinically localized PCa completed a mail-in paper-and-pencil survey after they had made their treatment decision, but prior to treatment.

RESULTS

After adjusting for covariates, optimism and treatment decision-making self-efficacy were associated with less difficulty and greater satisfaction with the treatment decision-making process. Effects of optimism on difficulty and satisfaction were partially mediated by self-efficacy for making the treatment decision.

CONCLUSIONS

Men with PCa and who are low in optimism may be at greater risk for treatment decision-making difficulty and lack of treatment decision-making satisfaction, in part, because they have lower confidence in their ability to make the decision compared with those who are more optimistic. As self-efficacy perceptions are modifiable, consideration should be given to including self-efficacy enhancing components as part of PCa treatment decision-making interventions.

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.
