This study provides an illustration of a research design complementary to randomized controlled trial to evaluate program effects, namely, participatory peer research (PPR). The PPR described in current study was carried out in a small sample (N = 10) of young adults with mild intellectual disabilities (MID) and severe behavioral problems. During the PPR intervention, control and feedback to individuals is restored by training them to become participant-researchers, who collaborate in a small group of people with MID. Their research is aimed at the problems the young adults perceive and/or specific subjects of their interest. The study was designed as a multiple case study with an experimental and comparison group. Questionnaires and a semistructured interview were administered before and after the PPR project. Results of Reliable Change Index (RCI) analyses showed a decrease in self-serving cognitive distortions in the PPR group, but not in the comparison group. These results indicate that PPR helps to compensate for a lack of adequate feedback and control, and in turn may decrease distorted thinking and thereby possibly later challenging behavior.

BACKGROUND: We compared the effect of a 12-week group-based multidisciplinary self-management rehabilitation program, combining physical training (twice weekly) and cognitive-behavioral therapy (once weekly) with the effect of 12-week group-based physical training (twice weekly) on cancer survivors' quality of life over a 1-year period.MATERIALS AND METHODS: One hundred forty-seven survivors [48.8 +/- 10.9 years (mean +/- SD), all cancer types, medical treatment > or = 3 months ago] were randomly assigned to either physical training (PT, n = 71) or to physical training plus cognitive-behavioral therapy (PT + CBT, n = 76). Quality of life and physical activity levels were measured before and immediately after the intervention and at 3- and 9-month post-intervention using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 questionnaire and the Physical Activity Scale for the Elderly, respectively.RESULTS: Multilevel linear mixed-effects models revealed no differential pattern in change of quality of life and physical activity between PT and PT + CBT. In both PT and PT + CBT, quality of life and physical activity were significantly and clinically relevantly improved immediately following the intervention and also at 3- and 9-month post-intervention compared to pre-intervention (p < 0.001).CONCLUSION: Self-management physical training had substantial and durable positive effects on cancer survivors' quality of life. Participants maintained physical activity levels once the program was completed. Combining physical training with our cognitive-behavioral intervention did not add to these beneficial effects of physical training neither in the short-term nor in the long-term. Physical training should be implemented within the framework of standard care for cancer survivors.

OBJECTIVE: To conduct a randomized controlled trial and compare the effects on cancer survivors' quality of life in a 12-week group-based multidisciplinary self-management rehabilitation program, combining physical training (twice weekly) and cognitive-behavioral training (once weekly) with those of a 12-week group-based physical training (twice weekly). In addition, both interventions were compared with no intervention.METHODS: Participants (all cancer types, medical treatment completed > or = 3 months ago) were randomly assigned to multidisciplinary rehabilitation (n = 76) or physical training (n = 71). The nonintervention comparison group consisted of 62 patients on a waiting list. Quality of life was measured using the RAND-36. The rehabilitation groups were measured at baseline, after rehabilitation, and 3-month follow-up, and the nonintervention group was measured at baseline and 12 weeks later.RESULTS: The effects of multidisciplinary rehabilitation did not outperform those of physical training in role limitations due to emotional problem (primary outcome) or any other domains of quality of life (all p > .05). Compared with no intervention, participants in both rehabilitation groups showed significant and clinically relevant improvements in role limitations due to physical problem (primary outcome; effect size (ES) = 0.66), and in physical functioning (ES = 0.48), vitality (ES = 0.54), and health change (ES = 0.76) (all p < .01).CONCLUSIONS: Adding a cognitive-behavioral training to group-based self-management physical training did not have additional beneficial effects on cancer survivors' quality of life. Compared with the nonintervention group, the group-based self-management rehabilitation improved cancer survivors' quality of life.
