Psychometric properties of the Chinese version of the Infertility Self-Efficacy Scale

Abstract

Objective: To translate the English version of Infertility Self-Efficacy Scale into Chinese and to validate the psychometric properties of the Chinese version of the Infertility Self-Efficacy Scale (CISE). Method(s): Participants were recruited from the Gynecology Department of two city hospitals. Five main processes were involved in the formation of CISE [1]: scale translation based on expert consultation [2]; pre-test questionnaire development with infertile women's feedback (N = 20) [3]; factor structure assessed by exploratory and confirmatory factor analysis (N = 177) [4]; assessment of reliability by internal consistency (N = 177) and test-retest reliability (N = 21); and [5] assessment of convergent validity with Self-rating Anxiety Scale, Self-rating Depression Scale, and Simplified Coping Style Questionnaire (N = 177). Results: This study established a 16-item CISE. Factor analyses confirmed a one-component solution, which explained 54.59% of total variances and showed an acceptable model fit. Cronbach's α and test-retest correlation coefficients for the scale were 0.94 and 0.84, respectively. The CISE score was significantly correlated with anxiety (r = −0.47), depression (r = −0.60), positive coping style (r = 0.37), and certain negative coping style items. Conclusion: This 16-item CISE is a reliable and valid measure to evaluate perceived self-efficacy among a sample of Chinese women who underwent infertility treatment.
