Research note reliability and validity of Japanese version of the trauma-informed care provider survey (TIC provider survey).

OBJECTIVE: Robust instruments to evaluate the ability of trauma-informed care among healthcare workers need to be developed, as this would help the implementation of trauma-informed care to prevent re-traumatization of patients. This study aims to assess the reliability and validity of the Japanese version of the Trauma-Informed Care (TIC) Provider Survey. A total of 794 healthcare workers were surveyed using a self-administered questionnaire, including the TIC Provider Survey, and six measures that were considered to be correlated with it. We calculated the Cronbach's alpha coefficient to investigate the internal consistency of each category of the TIC Provider Survey (knowledge, opinions, self-rated competence, practices, and barriers). Spearman's rank correlation coefficients were used to investigate the correlation between each category of the TIC Provider Survey, and other measures of construct validity. RESULTS: Cronbach's alpha coefficients of each category of the TIC Provider Survey were 0.40 (Knowledge), 0.63 (Opinions), 0.92 (Self-rated competence), 0.93 (Practices), and 0.87 (Barriers). The Spearman's rank correlation coefficients were small. We confirmed the reliability of the acceptable levels and examined the validity of modest or unacceptable levels of the Japanese version of the TIC provider survey among Japanese workers in a healthcare setting.

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

BACKGROUND: 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.

Reliability and validity of the Japanese version of the INSPIRE measure of staff support for personal recovery in community mental health service users in Japan.

BACKGROUND: Supporting personal recovery in people with mental health difficulties is central to mental health services. This study aimed to develop the Japanese version of INSPIRE and Brief INSPIRE measure of staff support for personal recovery and to evaluate its reliability and validity. METHODS: A questionnaire survey was conducted from October to December 2015. The authors asked users to participate in the survey of 14 community mental health services in the Kanto region of Japan. The service users completed self-administered questionnaires that include the Japanese version of INSPIRE, the Recovery Assessment Scale, the Client Satisfaction Questionnaire, the patient version of the Scale to Assess Therapeutic Relationship in Community Mental Health care and the Short Form Health Survey. Internal consistency was assessed using Cronbach's alpha coefficient, and test-retest reliability was assessed using the intraclass correlation coefficient (ICC) and weighted kappa. Convergent validity was examined by assessing correlation with other scales. Factor validity was evaluated by exploratory factor analysis (EFA) with generalized least-squares mean and oblimin rotation. In addition, confirmatory factor analysis was used to check the fitness of the factor structure models derived from the EFA. RESULTS: A total of 195 out of 212 users gave written informed consent and participated in the study. Data from 190 respondents were analyzed (response rate 89.6%). INSPIRE, Brief INSPIRE, and the subscales all showed Cronbach's alpha coefficient over 0.78. ICC and weighted kappa derived more than 0.92 for subscales and Brief INSPIRE. These numerical values indicated good reliability. The convergent validity of Brief INSPIRE and the subscales was significantly positively correlated with the other scales. Different from the previous study, the factor structure was extracted using EFA. Both factor structures were checked by CFA, but the degree of fitness index was not good in either. Therefore, the factor analysis did not show goodness of fit. CONCLUSIONS: This study found the Japanese version of INSPIRE and Brief INSPIRE to be reliable and valid for use among community mental health service users in Japan.

Correction to: The Japanese version of the questionnaire about the process of recovery: development and validity and reliability testing.

After publication of our article [1] we were notified that the 5-point Likert-type scale in Additional file 1 needs to change from "1 to 5" to "0 to 4". The updated Additional file 1 is included in this correction.

The Japanese version of the questionnaire about the process of recovery: development and validity and reliability testing.

BACKGROUND: Personal recovery is increasingly recognised as an important outcome measure in mental health services. This study aimed to develop a Japanese version of the Questionnaire about the Process of Recovery (QPR-J) and test its validity and reliability. METHODS: The study comprised two stages that employed the cross-sectional and prospective cohort designs, respectively. We translated the questionnaire using a standard translation/back-translation method. Convergent validity was examined by calculating Pearson's correlation coefficients with scores on the Recovery Assessment Scale (RAS) and the Short-Form-8 Health Survey (SF-8). An exploratory factor analysis (EFA) was conducted to examine factorial validity. We used intraclass correlation and Cronbach's alpha to examine the test-retest and internal consistency reliability of the QPR-J's 22-item full scale, 17-item intrapersonal and 5-item interpersonal subscales. We conducted an EFA along with a confirmatory factor analysis (CFA). RESULTS: Data were obtained from 197 users of mental health services (mean age: 42.0 years; 61.9% female; 49.2% diagnosed with schizophrenia). The QPR-J showed adequate convergent validity, exhibiting significant, positive correlations with the RAS and SF-8 scores. The QPR-J's full version, subscales, showed excellent test-retest and internal consistency reliability, with the exception of acceptable but relatively low internal consistency reliability for the interpersonal subscale. Based on the results of the CFA and EFA, we adopted the factor structure extracted from the original 2-factor model based on the present CFA. CONCLUSION: The QPR-J is an adequately valid and reliable measure of the process of recovery among Japanese users with mental health services.
