Reliability and Validity of the Japanese Version of the Attitudes Related to Trauma-Informed Care (ARTIC-10) Scale

Trauma-informed care is recommended to avoid the inadvertent retraumatization of patients by health care providers. Psychometric evaluation of trauma-informed care instruments is needed. The Japanese version of the Attitudes Related to Trauma-Informed Care (ARTIC-10) Scale has not yet been psychometrically validated. OBJECTIVE: The study's objective was to examine the reliability and validity of the ARTIC-10. METHODS: This psychometric study of the ARTIC-10 compared with five other scales associated with attitudes related to trauma-informed care used a cross-sectional survey design conducted in November 2020 with a convenience sample of Japanese physicians and nurses recruited from an internet research agency. Participants completed self-administered questionnaires including the (a) ARTIC-10; (b) the Japanese version of the Moral Sensitivity Questionnaire 2018; (c) Patient Health Questionnaire-9; (d) Generalized Anxiety Disorder-7; (e) Stress Underestimation Beliefs; and (f) Negative Acts Questionnaire-Revised. Cronbach's α measured reliability internal consistency, and construct validity was measured by Spearman's rank. RESULTS: A total of 794 physicians and nurses completed the surveys. Cronbach's α value of ARTIC-10 was 0.56. Higher scores of ARTIC-10 were positively and significantly correlated with Moral Sensitivity Questionnaire 2018 and negatively and significantly correlated with other scales (r =−.12 to .30). CONCLUSION: This study found only modest internal consistency and construct validity of the Japanese version of ARTIC-10 in physicians and nurses. Further study is needed to identify factors that affect the reliability and validity of this Japanese scale to improve its psychometric properties.
