Goal processes in relation to goal attainment: predicting health-related quality of life in myocardial infarction patients.

Goal theory suggests that both goal attainment and psychological processes concerning goal pursuit can influence a patient's (health-related) quality of life (HRQL) (e.g. Carver & Scheier, 1999). In the present longitudinal study, 46 MI patients completed questionnaires shortly after hospitalization and four months later, assessing a health, social and individual goal for the coming year, goal conflict, goal self-efficacy, goal attainment and HRQL. The results of a multiple regression analysis suggest that both goal conflict and goal self-efficacy predict goal attainment. Furthermore, goal self-efficacy appeared to be an independent predictor of physical and social HRQL. Goal attainment had a medium effect on social HRQL, but its effect was mediated by goal conflict and goal self-efficacy. A goal theory perspective seems to offer additional insights into HRQL after an MI.
