RESUMEN
PURPOSE: Many cancer survivors seek complementary therapies (CTs) to improve their quality of life. While it is well-known that women who are younger, more highly educated, and have higher incomes are more likely to use CTs, individual differences such as personality factors have been largely unexplored as predictors of CT use. METHODS: In a secondary analysis of a larger study, 270 women with stage I to III breast cancer completed self-report measures of demographic and illness-related information, personality variables, and use of several different types of CTs. A series of logistic regression models were used to explore whether demographic, illness-related, and personality variables predicted different types of CT use. RESULTS: Prior relationships between education and CT use were replicated. There were no significant relationships between illness-related variables and different types of CT use. Of the 5 personality factors, only openness to experience was a significant predictor of multiple types of CT use. CONCLUSIONS: Openness to experience may represent an individual difference variable that predicts CT use among cancer survivors. CTs themselves may represent a form of intellectual curiosity and novelty seeking. Further studies are needed to replicate and examine the generalizability of the relationship between openness to experience and CT use in oncology populations.

Despite growing evidence in support of mindfulness as an underlying mechanism of mindfulness-based interventions (MBIs), it has been suggested that nonspecific therapeutic factors, such as the experience of social support, may contribute to the positive effects of MBIs. In the present study, we examined whether change in mindfulness and/or social support mediated the effect of Mindfulness-Based Cancer Recovery (MBCR) compared to another active intervention (i.e. Supportive Expressive Group Therapy (SET)), on change in mood disturbance, stress symptoms and quality of life. A secondary analysis was conducted of a multi-site randomized clinical trial investigating the impacts of MBCR and SET on distressed breast cancer survivors (MINDSET). We applied the causal steps approach with bootstrapping to test mediation, using pre- and post-intervention questionnaire data of the participants who were randomised to MBCR (n = 69) or SET (n = 70). MBCR participants improved significantly more on mood disturbance, stress symptoms and social support, but not on quality of life or mindfulness, compared to SET participants. Increased social support partially mediated the impact of MBCR versus SET on mood disturbance and stress symptoms. Because no group differences on mindfulness and quality of life were observed, no mediation analyses were performed on these variables. Findings showed that increased social support was related to more improvement in mood and stress after MBCR compared to support groups, whereas changes in mindfulness were not. This suggests a more important role for social support in enhancing outcomes in MBCR than previously thought.

BACKGROUND: Although published studies report that screening for distress (SFD) improves the quality of care for patients with cancer, little is known about how SFD impacts healthcare professionals (HCPs). OBJECTIVES: This quality improvement project examined the impact of implementing the SFD intervention on HCPs' confidence in addressing patient distress and awareness of person-centered care. PATIENTS AND METHODS: This project involved pre-evaluation and post-evaluation of the impact of implementing SFD. A total of 254 HCPs (cohort 1) were recruited from 17 facilities across the province to complete questionnaires. SFD was then implemented at all cancer care facilities over a 10-month implementation period, after which 157 HCPs (cohort 2) completed post-implementation questionnaires. At regional and community care centers, navigators supported the integration of SFD into routine practice; therefore, the impact of navigators was examined. RESULTS: HCPs in cohort 2 reported significantly greater confidence in managing patients' distress and greater awareness about person-centered care relative to HCPs in cohort 1. HCPs at regional and community sites reported greater awareness in person-centeredness before and after the intervention, and reported fewer negative impacts of SFD relative to HCPs at tertiary sites. Caring for single or multiple tumor types was an effect modifier, with effects observed only in the HCPs treating multiple tumors. CONCLUSIONS: Implementation of SFD was beneficial for HCPs' confidence and awareness of person-centeredness. Factors comprising different models of care, such as having site-based navigators and caring for single or multiple tumors, influenced outcomes.

BACKGROUND: Mindfulness-based cancer recovery (MBCR) and supportive expressive group therapy (SET) are two well-validated psychosocial interventions, but they have not been directly compared, and little is known about long-term outcomes. This comparative effectiveness study measured the effects of these two interventions immediately following the groups and for 1 year thereafter in distressed breast cancer survivors. METHODS: Two hundred fifty-two distressed Stage I-III breast cancer survivors were randomized into either MBCR or SET. Women completed questionnaires addressing mood, stress symptoms, quality of life, social support, spirituality and post-traumatic growth before and after the interventions, and 6 and 12 months later. RESULTS: Immediately following the intervention, women in MBCR reported greater reduction in mood disturbance (primarily fatigue, anxiety and confusion) and stress symptoms including tension, sympathetic arousal and cognitive symptoms than those in SET. They also reported increased emotional and functional quality of life, emotional, affective and positive social support, spirituality (feelings of peace and meaning in life) and post-traumatic growth (appreciation for life and ability to see new possibilities) relative to those in SET, who also improved to a lesser degree on many outcomes. Effect sizes of the time × group interactions were small to medium, and most benefits were maintained over 12 months of follow-up. CONCLUSIONS: This study is the first and largest to demonstrate sustained benefits of MBCR in distressed breast cancer survivors relative to an active control. MBCR was superior to SET for improving psychological well-being with lasting benefits over 1 year, suggesting these women gained long-lasting and efficacious tools to cope with cancer.

BACKGROUND: Although a number of accreditation agencies and professional societies recommend routine screening for distress (SFD) for patients with cancer, it has been integrated very slowly into clinical practice. OBJECTIVES: This evaluation investigated the impact of a large-scale SFD intervention on patients' quality of life, symptom reports, and psychosocial well-being. The SFD intervention involved (1) completion of the SFD tool by patients, (2) discussion between patient and provider about the concerns indicated, and (3) provision of appropriate assessments/interventions based on priority concerns. PATIENTS AND METHODS: This quality improvement work included a pre-evaluation and postevaluation of the impact of implementation on patients' well-being. Patients in cohort 1 (N=740) were surveyed before implementation, whereas patients in cohort 2 (N=534) were surveyed 10 months after the implementation at 17 clinics province-wide. As part of the implementation, providers received training on assessing and responding to patient priority concerns with the standardized tool. RESULTS: No differences were seen in total score of quality of life between the cohorts. Fewer patients in cohort 2 than in cohort 1 reported health problems, including tiredness, drowsiness, poor appetite, nausea, anxiety, and poor well-being. Similarly, significantly fewer patients in cohort 2 endorsed problems relating to emotional, practical, informational, spiritual, social, and physical aspects of well-being. CONCLUSIONS: Results showed significantly improved psychological and physical symptoms and psychosocial well-being after routine SFD was implemented, suggesting that a large-scale SFD intervention is beneficial for patients when it is integrated into existing clinical practice and community resources.

OBJECTIVE: High levels of high-frequency heart rate variability (HF-HRV), related to parasympathetic-nervous-system functioning, have been associated with longer survival in patients with myocardial infarction and acute trauma and in patients undergoing palliative care. From animal studies linking higher vagal activity with better immune system functioning and reduced metastases, we hypothesized that higher HF-HRV would predict longer survival in patients with metastatic or recurrent breast cancer (MRBC). METHODS: Eighty-seven patients with MRBC participated in a laboratory task including a 5-minute resting baseline electrocardiogram. HF-HRV was computed as the natural logarithm of the summed power spectral density of R-R intervals (0.15-0.50 Hz). In this secondary analysis of a study testing whether diurnal cortisol slope predicted survival, we tested the association between resting baseline HF-HRV on survival using Cox proportional hazards models. RESULTS: A total of 50 patients died during a median follow-up of 7.99 years. Higher baseline HF-HRV predicted significantly longer survival, with a hazard ratio of 0.75 (95% confidence interval = 0.60-0.92, p = .006). Visceral metastasis status and baseline heart rate were related to both HF-HRV and survival. However, a combination of HF-HRV and heart rate further improved survival prediction, with a hazard ratio of 0.64 (95% confidence interval = 0.48-0.85, p = .002). CONCLUSIONS: Vagal activity of patients with MRBC strongly predicted their survival, extending the known predictive window of HF-HRV in cancer beyond palliative care. Vagal activity can be altered by behavioral, pharmacological, and surgical interventions and may be a promising target for extending life expectancy in patients with metastasizing cancer.

BACKGROUND: Group psychosocial interventions including mindfulness-based cancer recovery (MBCR) and supportive-expressive group therapy (SET) can help breast cancer survivors decrease distress and influence cortisol levels. Although telomere length (TL) has been associated with breast cancer prognosis, the impact of these two interventions on TL has not been studied to date. METHODS: The objective of the current study was to compare the effects of MBCR and SET with a minimal intervention control condition (a 1-day stress management seminar) on TL in distressed breast cancer survivors in a randomized controlled trial. MBCR focused on training in mindfulness meditation and gentle Hatha yoga whereas SET focused on emotional expression and group support. The primary outcome measure was relative TL, the telomere/single-copy gene ratio, assessed before and after each intervention. Secondary outcomes were self-reported mood and stress symptoms. RESULTS: Eighty-eight distressed breast cancer survivors with a diagnosis of stage I to III cancer (using the American Joint Committee on Cancer (AJCC) TNM staging system) who had completed treatment at least 3 months prior participated. Using analyses of covariance on a per-protocol sample, there were no differences noted between the MBCR and SET groups with regard to the telomere/single-copy gene ratio, but a trend effect was observed between the combined intervention group and controls (F [1,84], 3.82; P = .054; η(2) = .043); TL in the intervention group was maintained whereas it was found to decrease for control participants. There were no associations noted between changes in TL and changes in mood or stress scores over time. CONCLUSIONS: Psychosocial interventions providing stress reduction and emotional support resulted in trends toward TL maintenance in distressed breast cancer survivors, compared with decreases in usual care.

Studies indicate that story-telling and emotional expression may be important therapeutic mechanisms. This study examined how they work together over 1 year of supportive-expressive group therapy (SET). Participants were 41 women randomized to SET. We coded emotional expression and story types (story vs. non-story) at the initial session, 4, 8, and 12 months. Women engaged in more storytelling in their initial than later sessions. In later sessions, women expressed significantly more emotion, specifically compassion and high-arousal positive affect. Direct communication (non-story) allowed more positive but also more defensive expression as women supported and challenged each other. Greater hostility in non-story and greater constrained anger during story were associated with increasing depression. Greater high-arousal positive affect in non-story and greater primary negative affect in story were associated with increasing social network size. These results inform clinicians about cues they might use to improve the effectiveness of cancer support groups.

Clinicians working with cancer patients listen to them, observe their behavior, and monitor their physiology. How do we proceed when these indicators do not align? Under self-relevant stress, non-cancer repressors respond with high arousal but report low anxiety; the high-anxious report high anxiety but often have lower arousal. This study extends discrepancy research on repressors and the high-anxious to a metastatic breast cancer sample and examines physician rating of coping. Before and during a Trier Social Stress Test (TSST), we assessed affect, autonomic reactivity, and observers coded emotional expression from TSST videotapes. We compared non-extreme (N = 40), low-anxious (N = 16), high-anxious (N = 19), and repressors (N = 19). Despite reported low anxiety, repressors expressed significantly greater Tension or anxiety cues. Despite reported high anxiety, the high-anxious expressed significantly greater Hostile Affect rather than Tension. Physicians rated both groups as coping significantly better than others. Future research might productively study physician-patient interaction in these groups.

BACKGROUND: Mindfulness-based cancer recovery (MBCR) and supportive-expressive therapy (SET) are well-validated psycho-oncological interventions, and we have previously reported health benefits of both programs. However, little is known about patients' characteristics or program preferences that may influence outcomes. Therefore, this study examined moderators of the effects of MBCR and SET on psychological well-being among breast cancer survivors. METHODS: A multi-site randomized controlled trial was conducted between 2007 and 2012 in two Canadian cities (Calgary and Vancouver). A total of 271 distressed stage I-III breast cancer survivors were randomized into MBCR, SET or a 1-day stress management seminar (SMS). Baseline measures of moderator variables included program preference, personality traits, emotional suppression, and repressive coping. Outcome measures of mood, stress symptoms, quality of life, spiritual well-being, post-traumatic growth, social support, and salivary cortisol were measured pre- and post intervention. Hierarchical regression analyses were used to assess moderator effects on outcomes. RESULTS: The most preferred program was MBCR (55%). Those who were randomized to their preference improved more over time on quality of life and spiritual well-being post-intervention regardless of the actual intervention type received. Women with greater psychological morbidity at baseline showed greater improvement in stress symptoms and quality of life if they received their preferred versus nonpreferred program. CONCLUSIONS: Patients' program preference and baseline psychological functioning, rather than personality, were predictive of program benefits. These results suggest incorporating program preference can maximize the efficacy of integrative oncology interventions, and emphasize the methodological importance of assessing and accommodating for preferences when conducting mind-body clinical trials.

PURPOSE: To compare the efficacy of the following two empirically supported group interventions to help distressed survivors of breast cancer cope: mindfulness-based cancer recovery (MBCR) and supportive-expressive group therapy (SET). PATIENTS AND METHODS: This multisite, randomized controlled trial assigned 271 distressed survivors of stage I to III breast cancer to MBCR, SET, or a 1-day stress management control condition. MBCR focused on training in mindfulness meditation and gentle yoga, whereas SET focused on emotional expression and group support. Both intervention groups included 18 hours of professional contact. Measures were collected at baseline and after intervention by assessors blind to study condition. Primary outcome measures were mood and diurnal salivary cortisol slopes. Secondary outcomes were stress symptoms, quality of life, and social support. RESULTS: Using linear mixed-effects models, in intent-to-treat analyses, cortisol slopes were maintained over time in both SET (P = .002) and MBCR (P = .011) groups relative to the control group, whose cortisol slopes became flatter. Women in MBCR improved more over time on stress symptoms compared with women in both the SET (P = .009) and control (P = .024) groups. Per-protocol analyses showed greater improvements in the MBCR group in quality of life compared with the control group (P = .005) and in social support compared with the SET group (P = .012). CONCLUSION: In the largest trial to date, MBCR was superior for improving stress levels, quality of life and social support [CORRECTED] for distressed survivors of breast cancer. Both SET and MBCR also resulted in more normative diurnal cortisol profiles than the control condition. The clinical implications of this finding require further investigation.

OBJECTIVE: This study sought to identify relationships between trait mindfulness, repressive, and suppressive emotional styles, and the relative importance of these traits in their association with self-reported psychological health among women with breast cancer. METHOD: Of the 277 women with breast cancer accrued in the study, 227 (81.9%) completed a set of questionnaires assessing personality traits, stress symptoms, and mood. RESULTS: High levels of mindfulness were associated with fewer stress-related symptoms and less mood disturbance, while high levels of suppression were associated with poorer self-reported health. CONCLUSION: Individuals' dispositional ways to manage negative emotions were associated with the experience of symptoms and aversive moods. Helping patients cultivate mindful insights and reduce deliberate emotional inhibition may be a useful focus for psycho-oncological interventions.

BACKGROUND: Mindfulness-based stress reduction (MBSR) has demonstrated efficacy for alleviating cancer-related distress. Although theorized to be the means by which people improve, it is yet to be determined whether outcomes are related to the development or enhancement of mindfulness among participants. This study examined the effect of participation in an MBSR program on levels of mindfulness in a heterogeneous sample of individuals with cancer, and if these changes were related to improvements in stress and mood outcomes. METHODS: In all, 268 individuals with cancer completed self-report assessments of stress and mood disturbances before and after participation in an 8-week MBSR program. Of these, 177 participants completed the Mindful Attention Awareness Scale and 91 participants completed the Five Facet Mindfulness Questionnaire, at both time points. RESULTS: Levels of mindfulness on both measures increased significantly over the course of the program. These were accompanied by significant reductions in mood disturbance (55%) and symptoms of stress (29%). Increases in mindfulness accounted for a significant percentage of the reductions in mood disturbance (21%) and symptoms of stress (14%). Being aware of the present moment and refraining from judging inner experience were the 2 most important mindfulness skills for improvements of psychological functioning among cancer patients. CONCLUSIONS: These results add to a growing literature measuring the impact of mindfulness and its relationship to improved psychological health. Moreover, specific mindfulness skills may be important in supporting these improvements.

OBJECTIVES: The purpose of these two studies was to assess how repressors and defensive, high-anxious individuals exhibit their psychological and health characteristics subjectively through self-reports and objectively through physiological markers and ratings of emotional expression. DESIGN: Cross-sectional descriptive design (study one) and randomized controlled design (study two). METHODS: In the first descriptive study, repressors, defensive, high-anxious individuals and low-anxious individuals were identified from a pool of 748 undergraduates. Participants were asked to complete questionnaires assessing psychological and health characteristics. In the second experimental study, the three groups were randomized into either emotional or non-emotional writing conditions. Participants were asked to write three essays on either an emotional or a non-emotional topic in a single day. RESULTS: In the first study, defensive, high-anxious individuals reported significantly more distress, symptoms, sickness behaviours and difficulty expressing anger relative to repressors. In the second study, there was a significant difference in salivary cortisol concentrations between the two writing conditions regardless of the emotional coping grouping. Analysis of the writing showed no significant differences among repressors, defensive, high-anxious and low-anxious individuals in their cognitive and affective expression. CONCLUSIONS: Whereas self-reports of health outcomes and psychological traits clearly distinguish repressors and defensive, high-anxious individuals, more objective indices of emotional expressiveness and physiology do not appear to do so. The results also indicate that expressive writing may be helpful to reduce physiological arousal towards emotionally charged memories.

AIM: This study investigated the attitudes and preferences of staff, residents and relatives of residents in a retirement village towards a health-care robot. METHODS: Focus groups were conducted with residents, managers and caregivers, and questionnaires were collected from 32 residents, 30 staff and 27 relatives of residents. RESULTS: The most popular robot tasks were detection of falls and calling for help, lifting, and monitoring location. Robot functionality was more important than appearance. Concerns included the loss of jobs and personal care, while perceived benefits included allowing staff to spend quality time with residents, and helping residents with self-care. Residents showed a more positive attitude towards robots than both staff and relatives. CONCLUSIONS: These results provide an initial guide for the tasks and appearance appropriate for a robot to provide assistance in aged care facilities and highlight concerns.

Medical and demographic characteristics and psychological morbidity of individuals with cancer prior to a psychosocial intervention can influence the efficacy of interventions. However, little is known about the moderating role of patients' psychosocial characteristics on intervention effects. This review sought to identify and synthesize the impacts of psychosocial moderators of the effect of psychosocial interventions on the psychological well-being of cancer patients. A systematic review of the published literature was conducted. Databases searched included PsycINFO, PubMed, MEDLINE, Scopus, CINAHL, Web of Science, and Psychology and Behavioural Sciences Collection. Randomized controlled studies examining a moderator effect of patients' psychosocial characteristics other than baseline depression and anxiety levels were included. Of 199 potential papers, a total of 20 studies, involving 3,340 heterogeneous cancer patients are included. Of the 17 potential psychosocial moderators examined in this review, 14 significantly moderated the effects of interventions. Moderators were categorized into personality traits, mental and physical quality of life, social environment, and self-efficacy. Patients with poorer quality of life, interpersonal relationships and sense of control benefitted more from interventions than those who already had adequate resources. Patients with low levels of optimism and neuroticism, high levels of emotional expressiveness, interpersonal sensitivity, and dispositional hypnotizability also showed greater benefits from various interventions. This review adds to the growing literature aimed at personalizing psychosocial cancer treatment by identifying who benefits from which psychosocial interventions.

This study aimed to explore criteria for shift work tolerance and to investigate the relationships between personality traits and states and shift work tolerance. Eighty-nine policemen and police women completed a questionnaire, once during consecutive night shifts and again during rotating shifts, and their responses were used to assess anxiety, emotional control, positive and negative affect, health complaints, sleep quality, difficulties in social and domestic life, and perceptions about shift work. Both the criteria for tolerance and the relationship between tolerance and personality varied according to shift type. Night shift tolerance involved four factors--somatic health, flexibility, sleep and sleep need--while rotating shift tolerance involved three factors--somatic health, flexibility and fatigue. Tolerance of shift work was associated with anxiety, repressive emotional style and mood. During night shifts, anxiety was the most influential personality factor for the somatic health and sleep dimensions of shift tolerance. During rotating shifts, positive and negative moods, rather than trait personality factors, were important predictors of the somatic health and fatigue shift tolerance dimensions. These results suggest a mechanism for more effective matching of workers to suitable shift schedules.
