Curvilinear associations between benefit finding and psychosocial adjustment to breast cancer

Two previously studied cohorts of women with nonmetastatic breast cancer (Ns = 230 and 136) were reexamined. Participants were assessed during the year after surgery and 5-8 years later. Associations were examined between benefit finding (BF) and several indicators of psychosocial adjustment (e.g., perceived quality of life, positive affect, negative affect, social disruption, and intrusive thoughts). Significant curvilinear relations between BF and other outcomes were observed cross-sectionally during initial assessment and at long-term follow-up in both samples. Compared with the intermediate BF group, low and high BF groups had better psychosocial adjustment. Further analyses indicated that the high BF group reported higher optimism and more use of positive reframing and religious coping than the other BF groups. Discussion highlights the need to examine nonlinear as well as linear relationships.

Cognitive-Behavioral Stress Management Reverses Anxiety-Related Leukocyte Transcriptional Dynamics

BACKGROUND Chronic threat and anxiety are associated with pro-inflammatory transcriptional profiles in circulating leukocytes, but the causal direction of that relationship has not been established. This study tested whether a cognitive-behavioral stress management (CBSM) intervention targeting negative affect and cognition might counteract anxiety-related transcriptional alterations in people confronting a major medical threat. METHODS One hundred ninety-nine women undergoing primary treatment of stage 0-III breast cancer were randomized to a 10-week CBSM protocol or an active control condition. Seventy-nine provided peripheral blood leukocyte samples for genome-wide transcriptional profiling and bioinformatic analyses at baseline, 6-month, and 12-month follow-ups. RESULTS Baseline negative affect was associated with >50% differential expression of 201 leukocyte transcripts, including upregulated expression of pro-inflammatory and metastasis-related genes. CBSM altered leukocyte expression of 91 genes by >50% at follow-up (group × time interaction), including downregulation of pro-inflammatory and metastasis-related genes and upregulation of type I interferon response genes. Promoter-based bioinformatic analyses implicated decreased activity of NF-κB/Rel and GATA family transcription factors and increased activity of interferon response factors and the glucocorticoid receptor as potential mediators of CBSM-induced transcriptional alterations. CONCLUSIONS In early-stage breast cancer patients, a 10-week CBSM intervention can reverse anxiety-related upregulation of pro-inflammatory gene expression in circulating leukocytes. These findings clarify the molecular signaling pathways by which behavioral interventions can influence physical health and alter peripheral inflammatory processes that may reciprocally affect brain affective and cognitive processes.

Intrinsic defects in B cell response to seasonal influenza vaccination in elderly humans.

We have evaluated the serum response to seasonal influenza vaccination in subjects of different ages and associated this with the specific B cell response to the vaccine in vitro. Although the serum response has previously been shown to decrease with age, this has largely been associated to decreased T cell functions. Our results show that in response to the vaccine, the specific response of B cells in vitro, as measured by AID (activation-induced cytidine deaminase), the in vivo serum HI (hemagglutination inhibition) response, and the in vivo generation of switch memory B cells are decreased with age, as evaluated in the same subjects. This is the first report to demonstrate that intrinsic B cell defects with age contribute to reduced antibody responses to the influenza vaccine. The level of AID in response to CpG before vaccination can also predict the robustness of the vaccine response. These results could contribute to developing more effective vaccines to protect the elderly as well as identifying those most at risk.

Stress Management Intervention Reduces Serum Cortisol and Increases Relaxation During Treatment for Nonmetastatic Breast Cancer

Objective: To examine the effects of a cognitive-behavioral stress management (CBSM) intervention, which was composed of relaxation, cognitive restructuring, and coping skills training on late afternoon serum cortisol and relaxation indicators in women who were undergoing treatment for nonmetastatic breast cancer. Methods: Participants (N = 128) were randomly assigned to receive a 10-week CBSM group intervention or a 1-day psychoeducation seminar. Serum cortisol was collected and ability to relax was assessed at study entry and again at 6- and 12-month follow-up visits. Data were analyzed using latent growth curve modeling. Results: There was a significant effect of study condition on change across time for both cortisol and perceived ability to relax. Women receiving CBSM had significantly greater reductions in cortisol levels across the 12 months compared with those in the control group, who had no appreciable decline. Women receiving CBSM reported greater increases in ability to relax than controls across time. Perceived ability to relax did not mediate CBSM-related reductions in cortisol. Conclusions: Women who participate in a 10-week CBSM intervention during treatment for breast cancer show decreases in physiological stress in parallel with increases in perceived relaxation skills. This is the first study demonstrating well-maintained reductions in cortisol after a CBSM intervention in cancer patients during and just after treatment. CBSM = cognitive-behavioral stress management; MOCS = Measure of Current Status; MOCSrelax = relaxation subscale of the MOCS; LGM = latent growth curve modeling; HPA = hypothalamic-pituitary-adrenal.

Illness perceptions and emotional well-being in men treated for localized prostate cancer☆

OBJECTIVE Emotional adjustment to cancer survivorship may be influenced by how patients interpret treatment side effects and other cancer-related experiences. The current study examined cognitive representations of illness, as conceptualized by the Self-Regulatory Model (SRM), in men treated for localized prostate cancer (PC). More severe PC perceptions were hypothesized to predict poorer emotional well being, particularly among men experiencing greater post-treatment sexual dysfunction or general life stress. METHODS The Perceived Stress Scale, Expanded Prostate Cancer Index Composite, Illness Perception Questionnaire-Revised, and Functional Assessment of Cancer Therapy were administered to 214 men within 18 months of completing treatment for early stage PC. RESULTS Perceptions that PC was less comprehensible, was less likely to be controlled by treatment, and was more likely caused by ones own personality and behaviors remained associated with poorer emotional well being after adjusting for relevant medical and demographic factors. Life stress moderated the relationship between perceived consequences of PC and emotional well-being, such that more severe perceptions of negative consequences predicted poorer emotional well-being only for men experiencing higher life stress. Degree of sexual dysfunction did not moderate any relationships between cancer perceptions and emotional well-being. CONCLUSION Within 18 months of completing treatment for localized PC, more severe perceived consequences of PC were associated with poorer emotional well-being, particularly among men experiencing greater life stress. Interventions that target distortions in illness perceptions may enhance emotional adjustment among the most distressed PC survivors.

The impact of improved self-efficacy on HIV viral load and distress in culturally diverse women living with AIDS: the SMART/EST women's project

The purpose of the present study was to determine whether changes in self-efficacy over time would be related to changes in disease progression markers (CD4, viral load) in a sample of women with AIDS. A self-efficacy measure was developed and two sub-scales emerged via factor analysis of 391 HIV-positive women: AIDS Self-efficacy and Cognitive Behavioral Skills Self-efficacy. Subsequently, the sub-scales and an additional adherence self-efficacy item were given to 56 HIV-positive women who were measured at two time points three months apart. Half of these women were randomly assigned to a CB intervention and half to a low intensity comparison condition. Increases in AIDS Self-efficacy over the three-month period were significantly related to increases in CD4 and decreases in viral load. Similarly, increases in Cognitive Behavioral Skills Self-efficacy were significantly related to decreases in distress over time. Findings were maintained within the intervention group alone. Interestingly, increases in cognitive behavioral skills self-efficacy and increases in the self-efficacy adherence item were also significantly related to decreases in viral load. Implications of the findings and suggestions for future research are discussed.

Perceived stress mediates the effects of coping on the quality of life of HIV-positive women on highly active antiretroviral therapy

This study examined the relationship between three HIV-specific coping strategies (cognitive coping strategies, denial, and religious coping) and quality of life (QoL) in 90 HIV+, predominately minority women on highly active antiretroviral therapy. Religious coping was unrelated to QoL; however, use of cognitive coping strategies was related to greater QoL, and denial was related to poorer QoL. Baron and Kennys model of mediation was then used to test perceived stress as a mediator of the relationships between denial and cognitive coping strategies and QoL. These relationships were both mediated by perceived stress. Results suggest that utilization of certain coping strategies may lessen or heighten perceptions of life stressfulness, thereby influencing QoL in this understudied population.

Medical illness and positive life change : can crisis lead to personal transformation?

The idea that people experience positive change through their struggles with adversity is very old. However, only recently has this idea generated widespread empirical research attention.People often claim to experience improved relationships with family and friends, a clearer sense of their own strengths and resilience, changed priorities about what is important in life, and various other positive changes after struggling with stressful or traumatic events. What are we to make of these claims? Can we determine whether perceptions of change reflect real, varifiable change - that is, is it possible for someone to believe that he or she has grown while still exhibiting the same old self-defeating thoughts and behaviors? Or, is the perception of change itself an important meaning reconstruction process? What factors influence personal growth, and what effect does growth have on physical and mental health?This book examines these issues in-depth and draws out implications for research and clinical practice. Because medical illness has been one of the primary contexts in which researchers have studied the phenomenon of positive life change, this book focuses on how positive life change might be fostered in the context of medical illness.

Long-term psychological benefits of cognitive-behavioral stress management for women with breast cancer: 11-year follow-up of a randomized controlled trial.

Breast cancer survivors experience long‐term physical and psychological sequelae after their primary treatment that negatively influence their quality of life (QOL) and increase depressive symptoms. Group‐based cognitive‐behavioral stress management (CBSM) delivered after surgery for early‐stage breast cancer was previously associated with better QOL over a 12‐month follow‐up and with fewer depressive symptoms up to 5 years after study enrollment. This 8‐ to 15‐year follow‐up (median, 11 years) of a previously conducted trial (NCT01422551) evaluated whether women in this cohort receiving CBSM had fewer depressive symptoms and better QOL than controls at an 8‐ to 15‐year follow‐up.

Perceived stress mediates the effects of social support on health-related quality of life among men treated for localized prostate cancer.

OBJECTIVE To examine the longitudinal effect of social support on general health-related quality of life (HRQOL) in men treated for localized prostate cancer, and to evaluate the role of perceived stress as a potential mediator of that relationship, in an ethnically and demographically diverse sample. METHODS Psychosocial assessments were administered to a sample of 175 men at baseline, and 2 years later. Hierarchical regression analyses were conducted to investigate the relationships between social support, perceived stress and HRQOL, while controlling for possible covariates that may affect HRQOL (e.g., age, time since diagnosis, medical comorbidities, etc.). RESULTS Higher levels of social support at baseline predicted higher levels of HRQOL at 2-year follow-up after controlling for relevant covariates and baseline levels of HRQOL. This relationship was partially mediated by level of perceived stress at baseline. Furthermore, men perceiving high levels of social support reported significantly higher HRQOL compared with men perceiving low levels of social support. CONCLUSIONS Results indicate positive social relationships contribute to improved HRQOL in patients who have undergone treatment for localized prostate cancer. One pathway through which social support can benefit HRQOL is through lower perceptions of stress. Enhancing or maintaining social support and reducing perceived stress may be potential targets for future psychosocial interventions aimed at improving HRQOL.
