The chain mediating role of social support and coping strategy: Type D personality and psychological distress among Chinese COPD patients

This study examines how coping strategies and social support mediate the relationship between type D personality and psychological distress in COPD patients. A sample of 351 patients completed surveys on demographics, psychological distress (Kessler Psychological Distress Scale), social support (Social Support SelfRating Scale), coping strategies (Chinese version of Medical Coping Modes Questionnaire), and type D personality (Type D Personality Scale). Using structural equation modeling (SEM) via AMOS 23.0 and SPSS, results showed that confrontation and acceptance-resignation coping strategies, as well as type D personality, were positively correlated with psychological distress, while social support was negatively correlated. SEM estimates revealed a chain mediating effect of social support and coping strategies between type D personality and psychological distress. Enhancing social support and coping strategies is crucial for reducing psychological distress, especially in COPD patients with type D personality. (c) 2024 Elsevier Inc.
