Psychometric Properties of Maternal Self-Efficacy Questionnaire in a Population of Iranian Mothers

Self-efficacy is an important indicator of a woman's successful transition to her maternal role and an important predictor of a mother's infant care behavior. This study aimed to evaluate the validity of the maternal self-efficacy scale in Iranian mothers. This cross-sectional study was conducted on 437 newly delivered mothers who were referred to health care centers in Bonab, Iran. A simple random sampling was performed. The research instrument included maternal self-efficacy. Translation validity was performed using the forward and backward translation method. Content validity was determined in qualitative (assessment of experts' opinions) and quantitative areas using the content validity ratio (CVR) and Content Validity Index (CVI). Face validity was determined on 30 newly delivered mothers. To determine the construct validity, exploratory factor analysis was used. The reliability was determined in terms of reproducibility via Intra-class correlation coefficient (ICC) by test-retest and internal consistency (Cronbach's alpha). CVI and CVR were 0.91 and 0.94 respectively. Further, the reliability was approved both in terms of reproducibility (ICC = 0.98) and internal consistency (alpha = 0.89). Construct validity was confirmed using exploratory factor analysis (KMO = 0.90, Bartlett's test p < 0.001) for the scale. The findings supported the validity and reliability of the research instrument. Therefore, it is recommended that the instrument can be used in both clinical practice and research.
