Psychosocial interventions affecting global perceptions of control in people with Parkinson’s disease: a scoping review

Purpose: Perceived control is an important construct for the psychological well-being of people affected by chronic conditions, and higher perceived control is associated with better outcomes. Psychosocial interventions have been trialled in these populations to improve both global and specific perceptions of control. However, most interventions involving people with Parkinson’s have focused on single-domain forms of control, while those addressing global perceived control are yet to be reviewed. This study aimed to identify and map the types of psychosocial interventions in individuals with Parkinson’s which have included forms of global perceived control as an outcome. Materials and Methods: Scoping review based on a search across MEDLINE, PsycINFO, CINAHL, Academic Search Ultimate. Results: From an initial return of 4388 citations, 12 citations were eventually included. These consisted of 8 quantitative and 4 qualitative studies, and covered 4 overarching categories of psychosocial interventions. Mixed results were found for cognitive, educational, and physical interventions, while a randomised controlled trial on mindfulness-based lifestyle programme showed more preliminary positive evidence. Conclusions: Further rigorous research is required on the topic to build on these preliminary findings. In the meantime, clinicians may need to consider programmes which proved effective with populations similar to people with Parkinson’s.IMPLICATIONS FOR REHABILITATION Perceived control is a psychological construct important for people with chronic illnesses, which can be targeted by psychosocial interventions. This article reviewed psychosocial interventions targeting global forms of perceived control in Parkinson’s. Mixed results were reported for the cognitive, educational, and physical interventions identified, while a randomised controlled trial on a mindfulness-based lifestyle programme showed more promising evidence. In the meantime, clinicians may need to consider programmes found to be effective with people with similar conditions to Parkinson’s.
