Cross‐cultural measurement equivalence of the Japanese version of Revised Conflict Tactics Scales Short Form among Japanese men and women

要旨

AIM: The Revised Conflict Tactics Scales Short Form (CTS2SF) is an instrument used to measure intimate partner violence (IPV) perpetration and victimization over the past 12 months. METHODS: The CTS2SF was translated into Japanese, and the reliability (internal consistency and 4-week test-retest reliability) and the concurrent and factor-based validity were examined using two waves of Internet surveys over an interval of 4 weeks. Participants of the survey were 393 Japanese men and women who were registrants of an Internet survey company. RESULTS: Cronbach's α was greater than 0.5 for most scales, while it was low (α = 0.18) for sexual coercion by partner. The test-retest reliability of the binary variable for the presence or absence of IPV was high (Yule's Q, 0.79-1.00), and moderate between the scores (Spearman's rank correlation, 0.38:0.70). Concordance with the Buss-Perry Aggression Questionnaire, Violence Against Women Screen, and Kessler 6 generally indicated good concurrent validity. The results of the exploratory factor analysis confirmed the three-factor structure of the Japanese version of the CTS2SF. CONCLUSION: Although the internal consistency reliability was limited for some sub-scales, its moderate internal consistency and test-retest reliability and good factor-based validity highlighted the benefit of using the Japanese version of the CTS2SF in a large-scale community survey where a shorter scale is required to assess IPV.
