Background: This study was aimed to test adaptability of the Contraceptive Self-Efficacy Scale (CSES) for use on Persian-speaking women of reproductive age.
Method: A preliminary draft of the Contraceptive Self Efficacy Scale (CSES) was prepared according to the standard translation/back translation procedures and an expert panel appraised its content and face validities. The approved draft was tested on 400 randomly selected women of reproductive age (15-49 years) at the 29th Bahman Hospital of in Tabriz, the capital city of East Azerbaijan province, North West of Iran from May to August 2018. The exploratory and confirmatory factor analysis (EFA, CFA) was carried out to verify the implicit factor structure of the CSES for use on Persian-speaking women of fertile age. The Cronbach's α and Interclass Correlation coefficients were estimated for internal consistency and accuracy assessment of the instrument.
Results: This translated scale indicated good internal consistency (0.9) and reliability (0.9). A four-factor solution best fitted the study data and the estimated fit indices were in the acceptable range (chi square/ degree of freedom = 2.956, the Root Mean Square Error of Approximation = 0.070, Confirmatory Fit Index = 0.667, The Tucker-Lewis Index = 0.599).
Conclusion: The CSES-P can be considered as a potentially valid and reliable tool to assess contraceptive self-efficacy among Persian-speaking women. The CSES-P is a general instrument to measure overall contraceptive self-efficacy of the Iranian reproductive age women and it would also be fascinating to work on method specific self-efficacy tools in future.
