Methods: Fifty-five men were assigned randomly to either the 12-week cognitive behavioral therapy based occupational therapy )OT-CBSM( intervention )treatment group( or a home program )control group( between March 2012 and August 2014 in the Department of Occupational Therapy, Faculty of Health Sciences, Hacettepe University, Ankara, Turkey. The Canadian Occupational Performance Measure )COPM( was used to measure the occupational performance and identify difficulties in daily living activities. The QoL and symptom status were measured by The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire C30 and its Prostate Cancer Module. A 12-week OT-CBSM intervention including client-centered training of daily living activities, recreational group activities, and cognitive behavioral stress management intervention were applied. Results: The COPM performance and satisfaction scores, which indicate occupational participation and QoL increased statistically in the treatment group in relation to men who were included in the home-program )p≤0.05(. Conclusion: A 12-week OT-CBSM intervention was effective in improving QoL in men treated for MPC, and these changes were associated significantly with occupational performance.

Huri et al 955 www.smj.org.sa Saudi Med J 2015; Vol. 36 )8( P cancer is one of the most frequent male malignancies in the world.1 The development of serum prostate-specific antigen )PSA( and advanced prostate cancer treatment modalities increased 10-year survival rates from ~60% to >70%.2 Prostate cancer can be occurred as a local disease or advanced metastatic disease. The standard of care for metastatic prostate cancer )MPC( is hormone )androgen blockade( therapy, which delays progression and relieves pain for an average of 18 months to 24 months.3,4 Nearly all patients who have hormone therapy eventually develop significant disease and treatment related morbidity including fatigue, decrease in bone density, bone pain, weight loss, gynecomastia, and hot flushes.3 Increased survival and subsequent functional, physical, and psychological needs produced a growing acceptance of understanding the rehabilitation needs to increase the occupational performance and quality of life )QoL( of the patients with MPC.5 Occupational therapy )OT(, one of the core elements of oncologic rehabilitation, is in a unique position to contribute to the development and fulfillment of occupational performance and participation with the motto of ‘live life to its fullest’.6 The role of the occupational therapist in oncology is to facilitate and enable an individual to achieve maximum functional performance, both physically and psychologically, in everyday living skills regardless of his or her life expectancy.6 Occupational performance or participation in everyday occupations is vital for all humans as defined by the International Classification of Functioning, Disability and Health7 )ICF(. Occupational performance has a positive influence on health, well-being, and the presence of cancer has been found to lead to participation in meaningful activities /occupations that are effected by the cancer and its treatments.8 Previous studies9-14 have ably identified OT interventions mostly in general oncology and palliative care. The literature on OT, specifically on patients with breast cancer, investigates management of pain, fatigue, nausea, metastatic patients intervention, stress reducing and management program, the value of engagement in meaningful activities, lymphedema, vocational rehabilitation, creative and therapeutic use of activity, cognitive therapy, and, changing life style with cognitive behavioral therapy.9-14 According to the literature, a survey on women with breast cancer provides a picture of the interventions employed by the occupational therapists and can help to create an OT service to regain the patients level of control and independence by maintaining or resuming engagement in purposeful occupations and meaningful activities; however, the effect of OT in patients’ QoL was not completely specified.15,16 Another interdisciplinary study recommended examination of the effectiveness of OT in patients’ functional needs and to promote evidence-based practice of OT in oncology.8,17 Prostate cancer oriented rehabilitation interventions may be valuable in functioning, and activity participation in daily living activities and also in helping men to acknowledge, express, accept, and use a problem solving approach on the changes that occur as a result of treatment and to seek out adaptive solutions for enduring fatigue, bone pain, weight loss, gynecomastia, and hot flushes.18 Such interventions may lead to significant improvements in functional, cognitive, and emotional coping skills, use of social support, utilization of health care, and management of symptoms.5,18-21 Rehabilitation interventions were adapted to meet the needs of cancer patients including functional individualized support and group therapy interventions22 and stress management intervention23 approaches. The research shows that effective stress management components include relaxation training to lower arousal, disease information and management, an emotionally supportive environment in which participants can address fears and anxieties, behavioral and cognitive coping strategies, and social support.19,20 Participation in rehabilitation intervention provides a clear and robust benefit to cancer patients by relieving treatment-related symptoms, reducing the physiologic concomitants of stress, and improving mood. Previous study19 found that the benefits in coping with cancer may be quite significant in male participants.19 This is supported by the positive experiences that men report from their participation in rehabilitation programs. Although, collectively, these findings indicated that men treated for prostate cancer derive benefit from a rehabilitation experience, most studies did not include a randomized intervention design and did not study the occupational performance of the participants.15,23 Only a few studies20,21 have investigated the efficacy of structured stress-management interventions in improving QoL and the mechanisms associated with such improvements despite stressful and negative side effects associated with treatment with limited activity participation. The limited reports in the literature indicates that there is a lack of study on the effect of OT combined Disclosure.

Huri et al 956 Saudi Med J 2015; Vol. 36 )8( www.smj.org.sa cognitive behavioral stress management skills in patients with MPC. In the current study, it was hypothesized that participants treated for MPC enrolled in the cognitive behavioral stress management based OT )OT-CBSM( would demonstrate greater improvements in occupational performance and QoL compared with a control group )CG( enrolled in the home-program. The objectives of this study were to identify the effect of OT-CBSM on occupational participation and QoL, and to explore the areas/activities of daily life that were the most commonly affected, and needed support in patients with MPC. Methods. Inclusion criteria were participants aged ≥50 years, under hormonal therapy )luteinizing hormone-releasing hormone agonists or maximal androgen blockade therapy( with pathologically confirmed adenocarcinoma of the prostate, stage T3 or T4 with bone metastasis, and no surgical castration history. Disease progression was defined by at least one of the following criteria: detection of a new bone lesion, rising serum PSA under hormone therapy, increased bone pain, or worsening clinical conditions. Participants with localized prostate adenocarcinoma or secondary malignancy, under 5 years education level, and with cognitive impairment or active psychiatric symptoms, including panic attacks, post-traumatic stress disorder, psychosis, or alcohol/drug dependence within the past 3 months were excluded. The study was conducted according to the Principles of the Helsinki Declaration and approved by the Institutional Review Board of Hacettepe University. Participants completed the evaluation tests one week before and one week after the intervention period. The study enrollment started in March 2012 and was completed in August 2014 in the Department of Occupational Therapy, Faculty of Health Sciences, Hacettepe University, Ankara, Turkey. A randomized, controlled study with 2 level of interventions )treatment or control( and 2 time points )initial and final( was conducted. The study design is shown in Figure 1. Participants were scheduled for an interview and received more intensive screening, including assessment of cognitive impairment. Participants who scored >23 on the mini-mental status examination24 were included in the study. Items from the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders25 )non-patient edition( were used to exclude participants with active suicidal ideation, panic attacks, post-traumatic stress disorder, psychosis, or alcohol/drug dependence.25 Participants with eligibility criteria and completed the socio-demographic form and evaluation tests. Cohorts ranging from 3-5 participants were recruited throughout the study. Participants were randomly assigned to either the treatment 12-week OT-CBSM or the control home program by flipping a coin. The control group )CG( was given a written home program after the first evaluation. Treatment group )TG( participants were reassessed in the first week after the 12-week intervention, whereas the control group were reassessed on the third week after their first evaluation to obtain the parallel time period between the pre-intervention and post-intervention assessments in both groups. All the participants were managed by the same master license therapist. Treatment group. Participants were given OT-CBSM in addition to hormone therapy. The 12-week OT-CBSM intervention is a combination of activity training and CBSM for prostate cancer, which was a modified protocol.20 In the current study, the groups met twice a week for 60 minute )totally 120 minutes/ week(, which included 30-minute client-centered individualized daily living activity training in the areas of self-care, productivity and/or leisure; 30-minute recreational activity group program; 40-minute didactic CBSM education as well as information related to MPC diagnosis and treatment and 20-minute practical different relaxation technique training. Control group. Participants were given a printed home-program and instructed on the effects of activity training, a recreational activity group program, stressmanagement skills, and relaxation skills. Participants were encouraged to practice independent self-care, productivity and recreational group activities, and use relaxation techniques of daily living in addition to hormone therapy. No didactic education or active recreational activity group program were provided to the CG. Evaluation materials. To identify the effect of OT-CBSM on occupational participation and QoL; the COPM and The European Organization for Research and Treatment of Cancer )EORTC( Core Quality of Life Questionnaire C30 )QLQ-C30( and its Prostate Cancer Module )EORTC QLQ-PR25(, and to explore areas/activities of daily life that were most commonly affected, and needed support for participants with MPC COPM were used. Occupational performance. The COPM was used with a semi-structured interview to measure the participants’ self-perception of his occupational performance and identify significant issues causing difficulties in daily activities in the areas of self-care, productivity, and leisure. Accordingly, the participant prioritizes up to 5 problems that are the most urgent Occupational therapy in prostate cancer ... Huri et al 957 www.smj.org.sa Saudi Med J 2015; Vol. 36 )8( or important and rates each of these problems on an ordinal 10-point scale regarding performance )1 = not able to do it at all and 10 = able to do it extremely well( and satisfaction )1 = not satisfied at all and 10 = extremely satisfied(. The mean scores for performance and satisfaction were obtained by adding the ratings of performance and satisfaction over the prioritized problems and dividing them by the number of prioritized problems. Participants were again instructed to re-evaluate performance and satisfaction regarding the prioritized problems of the first COPM interview. The mean scores were compared with the first evaluation scores.27 Quality of life. The QoL and health related QoL were measured by using The EORTC QLQ-C30 and the EORTC QLQ-PR25. The EORTC QLQ C30 consists of 30 items, which indicate the functions and symptoms of cancer patients. Six multi-item function scales were scored: physical function )PF(, role function )RF(, emotional function )EF(, social function )SF(, and global health status )GQoL(/quality of life )QoL(. Changes of ≥10 points on the GQoL/QoL scale were considered meaningful. Nine single-item scales )symptoms( were scored, including fatigue, pain, dyspnea, and gastrointestinal problems. All the scales of the test range from 0-100, in which a higher scale score represents a higher level of functioning. On the single-item scale, a higher score indicates more symptoms or problems.28 The EORTC QLQ-PR25 is a 25-item prostate cancer specific health related QoL questionnaire developed by EORTC. It has 4 domains, each has a various number of items: urinary symptoms )9 items(, bowel symptoms )4 items(, hormonaltreatment-related symptoms )6 items(, and sexual activity and functioning )6 items(. Each item was rated on a 4-point Likert-type scale )1 = very much, 2 = quite a bit, 3 = a little, 4 = not at all(. Higher scores indicate better health related QoL )namely, less symptomatic or better functioning(.29 The data were analyzed using the Statistical Package for Social Sciences version 17.0 )SPSS Inc, Chicago, IL, USA(. The group differences were assessed using the Wilcoxon rank sum test. Control variables were incorporated into main analyses if p-values were ≤0.05. Differences between individual cell means within each condition were analyzed using paired-sample Student t tests. In all cases, p-values ≤0.05 indicated statistical significance. The COPM performance and satisfaction scores were assessed by comparing the mean performance and the mean satisfaction scores of the first assessment with the mean scores of the reassessment. Results. In this study, we enrolled 55 male who received treatment for MPC for minimum of 12 months. Nine were unwilling to participate in the study and 12 were excluded as they did not fulfill the inclusion criteria. A total of 34 participants were included in the study )Figure 1(. All participants were assigned to either a 12-week OT-CBSM program )TG; n=19( or homeprogram )CG; n=15(. Table 1 summarizes the mean age, education level, and time span of hormone therapy. According to initial evaluation, the groups were similar )none of the participants characteristics were significantly different( at the 0.05 level )Table 1(. The initial evaluation occupational performance )performance score; p=0.002 and satisfaction score; p=0.001( and QoL )EORTCQLQ-C30; p=0.001( scores were similar in both goups at the 0.05 level. Occupational performance. We found significant differences between occupational performance score )COPM; mean performance and mean satisfaction scores( and initial and final evaluation scores in the TG )p≤0.05; Table 2(. Out of the 19 participants, 18 had an improvement )94.7%( and one had no change )5.2%( in the TG. No difference was found between the COPM mean performance and satisfaction scores in the CG )p>0.05; Table 2(. The most commonly affected activities that needed support according to the COPM were grooming, pulling up the duvet while in bed, driving a car, getting in and out of the bath, buttoning a shirt and dressing in the self-care category, walking up and down the stairs while carrying materials, typing, visiting other companies, storing groceries, and looking after grandchildren in the productivity category, and doing home repairment, playing outside with children/ grandchildren, walking the dog, going to a traditional Turkish cafe )only male goes to have time together, which traditional in Turkey( in leisure category, and other uncategorized examples such as using the telephone and reading newspaper while lying in bed or moving again after a period of inactivity. The participants had a group activity session according to the COPM on the areas of watching movies and preparing a movie booklet, gardening, poetry and preparing poem booklet, art, playing musical instrument, activity planning for grandfather-grandchildren time and making toys, photography and preparing a family album, searching, reading and discussing an area of interest such as theatre, history, or religion. A summary of the EORTC-QLQ-C30 and QLQ-PR25 functional scales and symptom scales are presented in Table 3. The TG participants reported a significant increase in physical functioning, role functioning, emotional functioning, and social functioning compared with the CG )p≤0.05, Occupational therapy in prostate cancer ...

The initial and final mean QLQ-PR25 scores are presented in Table 3. Sexual activity, urinary symptoms, hormonal treatment-related symptoms were significantly decreased in the TG )Table 3( according to final evaluation. Discussion. There are a few studies that report the positive effects of OT on daily living activities in various cancer populations.8-10,30 The effects of advanced OT interventions on QoL in individuals with cancer is still limited. This study tested the extent to which a 12-week OT-CBSM intervention improved perceived activity performance and satisfaction as evidenced by occupational performance and QoL among the participants treated for MPC. In the current study, we found that participation in our OT-CBSM intervention was associated with significant improvement in activity performance and satisfaction level for the activity, which is important for the participant. Additionally, daily living activity training caused improvement in activity performance and satisfaction level. Also, CBSM and Table 2 Occupational performance scores )performance and satisfaction scores of COPM(.
