Psychological Predictors of Fatigue, Work and Social Adjustment, and Psychological Distress in Rheumatology Outpatients

Abstract

Abstract. This study aims to investigate the longitudinal relationships between psychological variables and follow-up levels of fatigue, work and social adjustment, and psychological distress in people with rheumatic diseases. The study is a prospective observational study. Patients attending rheumatology outpatient appointments completed a questionnaire during their hospital visit and were mailed a follow-up questionnaire either at their next appointment or via postal questionnaire. Multivariate linear regression models examined the association between baseline cognitive behavioral responses, personality, social support and acceptance and follow-up levels of fatigue, work and social adjustment, and psychological distress, adjusting for age, gender, disease duration, and the length of time between baseline and follow-up. A total of 108 patients completed the follow-up questionnaires. The biggest predictors of having high levels of fatigue at follow-up were increased baseline damage beliefs and behavioral avoidance. Behavioral avoidance at baseline also had a strong relationship with worsened work and social adjustment at follow-up. The biggest predictor of psychological distress at follow-up was a lack of fatigue acceptance at baseline.
