Abstract

Background: Self-efficacy is an important predicator of coping with stress.

Objectives: This study aimed to determine the psychometric characteristics of the coping self-efficacy (CSE) scale among HIV-infected Iranian patients.

Patients and methods: Psychometric properties of the CSE scale were examined by using a cross-sectional study design. One hundred and twenty HIV-infected Iranian patients that had been referred to the Counseling of Behavioral Diseases Center at Imam Khomeini Hospital in Tehran, Iran in 2014 were selected through simple random sampling method. To determine the Content Validity Index (CVI) and the content validity ratio (CVR), a panel of experts (n = 20) reviewed items of CSE scale. Reliability was estimated through the internal consistency (n = 30) and the conformity factor analysis was performed.

Results: Iranian version of the CSE scale contained 16 items, including 7 items on the "use of problem-focused coping" method, 5 items on "stopping unpleasant emotions and thoughts", and 4 items on "getting support from friends and family". CVI and CVR scores were 0.79, 0.42 and more, respectively. Internal consistencies (range, 0.64 to 0.84) of 3 subscales were acceptable. Confirmatory factor analysis showed that comparative indices of the model, including CFI, IFI, GFI, RMSEA, and Chi-square (χ2/df) were 0.96, 0.95, 0.84, 0.83, and 1.82, respectively, which indicated a good fit for the data.

Conclusions: The Iranian version of the CSE scale is a valid instrument to measure the coping self-efficacy among people living with HIV in research and community settings in Iran.
