Exploring the Impact of Illness Perceptions, Self-efficacy, Coping Strategies, and Psychological Distress on Quality of Life in a Post-stroke Cohort.

ABSTRACT

This study evaluated the mediating role of self-efficacy, coping, depression and anxiety on the relationship between illness perceptions and quality of life in stroke survivors (n = 72; 32 females; mean [SD] age 65.09 [14.14] years; male mean [SD] age 69.83 [11.81]). Illness perceptions (Brief Illness Perceptions Questionnaire; BIPQ), coping styles (Carver Brief-COPE scale; B-COPE), depression/anxiety (Hospital Anxiety and Depression Scale; HADS), self-efficacy (General Self-Efficacy Scale; GSE) and quality of life (Assessment of quality of life; AQOL-6D) were analysed. Correlation analyses showed illness perception, maladaptive coping, self-efficacy, depression and anxiety to have a significant negative relationship with quality of life. Mediation analyses showed that while maladaptive coping and self-efficacy did not mediate the relationship between illness perception and quality of life, depression and anxiety did. The final model explained 76.74% of the variance in quality of life. Although based on a relatively small sample size, these results provide evidence for the important role of psychosocial factors in quality of life in post-stroke cohorts.
