RESUMO
The goal of this research is to utilize a transdisciplinary framework to guide the selection of putative moderators of the effectiveness of an intervention to promote physical activity behavior adoption and maintenance in the context of a randomized controlled intervention trial. Effective interventions to increase physical activity are sorely needed, and one barrier to the identification and development of such interventions is the lack of research targeted at understanding both the mechanisms of intervention efficacy and for whom particular interventions are effective. The purpose of this paper is to outline our transdisciplinary approach to understanding individual differences in the effectiveness of a previously successful exercise promotion intervention. We explain the rationale for and operationalization of our framework, characteristics of the study to which we apply the framework, and planned analyses. By embracing a transdisciplinary orientation for individual differences important in the prediction of physical activity (spanning molecular approaches, animal models, human laboratory models, and social psychological models), we hope to have a better understanding of characteristics of individuals that are important in the adoption and maintenance of physical activity.
RESUMO
Living with a chronic illness such as multiple sclerosis (MS) has significant psychosocial ramifications. In particular, the patient's relationship with a spouse or significant other is often negatively affected. Programs are needed to address the psychosocial challenges of the illness and help improve outcomes for both the person with MS and his or her romantic support partner. Relationship Matters (RM) is a relationship enrichment program that integrates information and resources of the National Multiple Sclerosis Society with empirically based marriage education. The purpose of this study was to examine the effectiveness of the RM program in increasing relationship satisfaction and aspects of health-related quality of life in couples living with MS over a 3-month follow-up period. Couples were given 8 hours of programming via in-person workshops disseminated across the country or teleconferences. A control group consisting of members of MS couples who did not receive the intervention was used for comparison. The results indicate that RM significantly improved relationship satisfaction over time compared with no intervention (P < .05). Additional findings include significant improvements in mental health-related quality of life as well as reported improvements in communication, conflict resolution, and ability to handle MS-specific relationship issues. Overall, these findings show that RM results in improved couple functioning and additional psychological health benefits for individuals with MS and their romantic support partners.
RESUMO
Alzheimer's disease can be particularly devastating to those who are caring for their loved one with the condition. There have been recent calls for the tailoring of caregiving interventions to examine outcome differences between groups of caregivers and the reporting of effectiveness via longitudinal and specific outcomes. The purpose of this study was to examine 3 interventions (psychoeducational training, a respite voucher-type grant, or their combination) while looking for possible group differences. A total of 367 caregivers participated in the study. Participants completed surveys and questionnaires before the intervention and at a 6-month follow-up. Positive outcomes were found, including lower depression scores, increased support service use, and increased support group usage. Possible effectiveness of the 3 types of interventions and variation among caregiver characteristics are discussed along with implications for future research.
