A validity and reliability study of the coping self‐efficacy scale

Objectives. Investigate the psychometric characteristics of the coping self‐efficacy (CSE) scale, a 26‐item measure of one's confidence in performing coping behaviors when faced with life challenges. Design. Data came from two randomized clinical trials ( N 1 = 149, N 2 = 199) evaluating a theory‐based Coping Effectiveness Training (CET) intervention in reducing psychological distress and increasing positive mood in persons coping with chronic illness. Methods. The 348 participants were HIV‐seropositive men with depressed mood who have sex with men. Participants were randomly assigned to intervention and comparison conditions and assessed pre‐ and post‐intervention. Outcome variables included the CSE scale, ways of coping, and measures of social support and psychological distress and well‐being. Results. Exploratory (EFA) and confirmatory factor analyses (CFA) revealed a 13‐item reduced form of the CSE scale with three factors: Use problem‐focused coping (6 items, α = .91), stop unpleasant emotions and thoughts (4 items, α = .91), and get support from friends and family (3 items, α = .80). Internal consistency and test–retest reliability are strong for all three factors. Concurrent validity analyses showed these factors assess self‐efficacy for different types of coping. Predictive validity analyses showed that residualized change scores in using problem‐ and emotion‐focused coping skills were predictive of reduced psychological distress and increased psychological well‐being over time. Conclusions. The CSE scale provides a measure of a person's perceived ability to cope effectively with life challenges, as well as a way to assess changes in CSE over time in intervention research.
