Gratitude, self-efficacy, and health-related quality of life in individuals with Parkinson's Disease

Parkinson's Disease (PD) is a chronic disease that can affect the physical, psychological, and social functioning of an individual. Minimal research has examined the relationship among positive psychological variables such as gratitude and self-efficacy and their relationship with health-related quality of life (HRQOL) in this population. Gender analyses have also been limited. The aim of this exploratory, cross-sectional study was to examine the relationship among gratitude, self-efficacy, and HRQOL by gender in individuals with Parkinson's Disease (PD). Participants included 102 individuals with PD (55 women; 42 men; 5 did not report gender) who completed questionnaires on gratitude (Gratitude Questionnaire-6), self-efficacy (General Self-Efficacy Scale), and HRQOL problems (Parkinson's Disease Questionnaire-39). Although there were no gender differences between gratitude, self-efficacy, or health-related quality of life problems, there were key gender differences in how those variables were related. Gratitude was associated with more HRQOL problems for women than men, whereas self-efficacy was associated with more HRQOL problems for men than women. In addition, self-efficacy emerged as a more important predictor of HRQOL problems for women and men than gratitude. This research could lead to targeted interventions by gender aimed at improving HRQOL in individuals with PD, particularly in building self-efficacy.
