Subjective and psychological well-being in Parkinson's Disease: A systematic review

Abstract

Objectives: The aim of this review is to summarize studies investigating subjective and psychological well-being in patients with Parkinson's disease (PD).

Materials and methods: A systematic and integrative review according to PRISMA criteria was performed with a literature search from inception up to September 2017 in multidisciplinary databases (PubMED, Scopus, Web of Knowledge) by combining together key words related to PD and well-being. Studies were included if: their full-text was available; they involved PD patients; focused on the selected positive dimensions; written in English. Case studies, conference proceedings, abstract, dissertations, book chapters, validation studies and reviews were excluded. Data extracted from the studies included sample characteristics, the positive dimension investigated, type of measure, study aims, design and results. One reviewer extracted details and commented results with other reviewers. The studies' quality was assessed following Kmet, Lee, and Cook.

Results: Out of 1425 studies extracted, 12 studies (9 quantitative, 2 qualitative, 1 mixed methods) involving 2204 patients with PD were included. Most of the studies had a cross-sectional design and/or evaluated the effect of physical rehabilitation on well-being. Articles documented that the illness could impair well-being for its progressive impact on patients' motor autonomy. Preserving motor and musculoskeletal functioning facilitate patients' experience of well-being, social contribution and the maintenance of their job.

Conclusions: Research on positive resources in PD is still scarce compared to other chronic illnesses. The few available investigations suggest the need of preserving motor abilities by proper rehabilitation programs for maintaining and/or promoting patients' well-being and life engagement.
