Mediating Effects of Self-Efficacy and Illness Perceptions on Mental Health in Men with Localized Prostate Cancer: A Secondary Analysis of the Prostate Cancer Patient Empowerment Program (PC-PEP) Randomized Controlled Trial.

Understanding how interventions reduce psychological distress in patients with prostate cancer is crucial for improving patient care. This study examined the roles of self-efficacy, illness perceptions, and heart rhythm coherence in mediating the effects of the Prostate Cancer Patient Empowerment Program (PC-PEP) on psychological distress compared to standard care. In a randomized controlled trial, 128 patients were assigned to either the PC-PEP intervention or standard care. The PC-PEP, a six-month program emphasizing daily healthy living habits, included relaxation and stress management, diet, exercise, pelvic floor muscle exercises, and strategies to improve relationships and intimacy, with daily activities supported by online resources and live sessions. Participants in the intervention group showed significant improvements in self-efficacy and specific illness perceptions, such as personal control and emotional response, compared to the control group. These factors mediated the relationship between the intervention and its psychological benefits, with self-efficacy accounting for 52% of the reduction in psychological distress. No significant differences in heart rhythm coherence were observed. This study highlights the critical role of self-efficacy and illness perceptions in enhancing psychological health in prostate cancer patients through the PC-PEP. The results underscore this program's effectiveness and the key mechanisms through which it operates. Given the high rates of distress among men undergoing prostate cancer treatments, these findings emphasize the importance of integrating the PC-PEP into clinical practice. The implementation of the PC-PEP in clinical settings can provide a structured approach to reducing psychological distress and improving overall patient well-being.

An Examination of the Relationship between Mental Distress, Functional and Psychosocial Quality of Life Indicators in a Population Based Sample of Prostate Cancer Survivors Who Received Curative Treatment.

INTRODUCTION: Although survival rates are highest among prostate cancer survivors compared to any other forms of cancer, nearly 60% suffer from mental distress. Here we examine urinary function and psychosocial stressors and their association with poor mental health in a younger group of prostate cancer survivors who have undergone curative treatment. METHODS: The study includes 128 men (47 to 70 years old) who received active treatment for prostate cancer, and completed a survivorship online survey between 2017 and 2018. Psychological distress was assessed with Kessler Psychological Distress Scale. International Prostate Symptom Score subscales (incomplete urinary emptying, frequency, intermittency, urgency, weak stream, straining and nocturia) and number of current prostate cancer survivorship stressors were predictors. Multivariate logistic regression was used to fit the model while controlling for months of survivorship since diagnosis, the presence or absence of surgery, radiation or hormone therapy treatment, current medication for depression and demographics. RESULTS: A total of 19.5% of men scored positive for current mental health issues. Prostate cancer survivors who reported increased number of current survivorship stressors (OR 1.48, 95% CI 1.09-2.01), had higher frequency of urination (OR 2.05, 95% CI 1.15-3.64), history of radiation treatment (OR 7.15, 95% CI 1.02-50.35) and were currently on prescribed medication for depression (OR 33.47, 95% CI 3.80-294.87) had higher odds for screening positive for psychological distress compared with their counterparts. CONCLUSIONS: These results corroborate recent findings showing an intersection between urological oncology and poor mental health during survivorship, and warrant the development of multidisciplinary teams in addressing survivorship issues in this population.

The Role of Response-Shift in Studies Assessing Quality of Life Outcomes Among Cancer Patients: A Systematic Review.

Objective: Response-shift has been cited as an important measurement consideration when assessing patient reported quality of life (QoL) outcomes over time among patients with severe chronic conditions. Here we report the results of a systematic review of response shift in studies assessing QoL among cancer patients. Methods: A systematic review using MEDLINE, EMBASE, and PsychINFO along with a manual search of the cited references of the articles selected, was conducted. A quality review was performed using STROBE criteria and reported according to PRISMA guidelines. Results: A systematic review of 1,487 records published between 1,887 and December 2018 revealed 104 potentially eligible studies, and 35 studies met inclusion criteria for content and quality. The most common cancer patient populations investigated in these studies were breast (18 studies), lung (14 studies), prostate (eight studies), and colorectal (eight studies). Response shift was identified among 34 of the 35 studies reviewed. Effect sizes were reported in 17 studies assessing QoL outcomes among cancer patients; 12 of which had negligible to small effect sizes, four reported medium effect sizes which were related to physical, global QoL, pain, and social (role) functioning and one reported a large effect size (fatigue). The most prevalent method for assessing response shift was the then-test, which is prone to recall bias, followed by the pre-test and post-test method. Given the heterogeneity among the characteristics of the samples and designs reviewed, as well as the overall small to negligible effect sizes for the effects reported, conclusions stating that changes due to internal cognitive shifts in perceived QoL should account for changes observed in cancer patients' QoL outcomes should be interpreted with caution. Conclusion: Further work is needed in this area of research. Future studies should control for patient characteristics, time elapsed between diagnosis and baseline assessment and evaluate their contribution to the presence of response shift. Time between assessments should include short and longer periods between assessments and evaluate whether the presence of response shift holds over time. Possible avenues for inquiry for future investigation are discussed.

Contributions of a retreat weekend to the healing and coping of cancer patients' relatives.

Relatives play a key role in the daily support and care of cancer patients. This role, however, can negatively affect relatives physically, psychologically, emotionally, and spiritually, challenging their health and well-being. Consequently, this could inhibit relatives' abilities to continue in their roles as caregivers. Although various studies have examined different interventions for the relatives of cancer patients, no formal research has been published on the role that retreat weekends play in their cancer journeys. In this qualitative study we used semistructured interviews to explore the experiences of 8 relatives who attended a "Skills for Healing Retreat Weekend" in Ontario, Canada. The findings indicate that the retreat, in bringing people together to partake in discussions and activities, fostered a sense of community among the participants. The retreat also had enduring effects, contributing to relatives' ongoing processes of healing as well as providing them with strategies for coping in their roles as caregivers.

Incomplete and inconsistent information provided to men making decisions for treatment of early-stage prostate cancer.

OBJECTIVES: To determine whether there is a gap between what patients know about early-stage prostate cancer and what they need to know to make treatment decisions, and whether the information patients receive varies depending on their treating physician. METHODS: Needs assessment was performed using a questionnaire consisting of 41 statements about early-stage prostate cancer. Statements were divided into six thematic subsets. Participants used a 5-point Likert scale to rate statements in terms of knowledge of the information and importance to a treatment decision. Information gaps were defined as significant difference between the importance and knowledge of an item. Descriptive statistics were used to describe demographic subscale scores. The information gap was analyzed by a paired t test for each thematic subset. One-way analyses of variance were used to detect any differences on the basis of treating physician. RESULTS: Questionnaires were distributed to 270 men (135 treated by radical prostatectomy, 135 by external beam radiotherapy). The return rate was 51% (138 questionnaires). A statistically significant information gap was found among all six thematic subsets, with five of the six P values less than 0.0001. Statistically significant variation was observed in the amount of information patients received from their treating physicians among four of the thematic subsets. CONCLUSIONS: There is an information gap between what early-stage prostate cancer patients need to know and the information they receive. Additionally there is a difference in the amount of information provided by different physicians.
