The property of the Japanese version of the Recovery Knowledge Inventory (RKI) among mental health service providers: a cross sectional study

Abstract

BackgroundThe Recovery Knowledge Inventory (RKI) is one of the influential scales to assess knowledge and attitude toward recovery-oriented practices among mental health service providers. In the present study, we aimed to develop a Japanese version of RKI and examine the validity and reliability.MethodsWe translated RKI into Japanese by reference to the guidelines for translating and adapting psychometric scales. A cross-sectional questionnaire survey was conducted with mental health service providers. Of a total of 475 eligible professionals, we used data from the 299 participants without missing value for the analyses (valid response rate = 62.9%). The questionnaire included Japanese RKI, Recovery Attitudes Questionnaire, The positive attitudes scale, and Japanese-language version of the Social Distance Scale. To examine the factorial validity of RKI, explanatory factor analysis and confirmatory factor analysis was employed. Convergent validity was assessed by calculating Pearson’s correlation coefficients between the total RKI score and the scores for the other three scales. We also calculated Cronbach’s α coefficients for the total score and for each domain of RKI to assess internal consistency reliability.ResultsThe participants’ mean age was 40.4 years and 30.4% were men. 20-item RKI did not provide any adequate or interpretable factor solutions at any number of factors by EFAs. Thus four items (#1, 4, 5, and 13) were subsequently eliminated in stages, then 16-item RKI was employed as a consequence for further analyses. EFA with four factor structures yielded marginally interpretable constitution. Each factor represented the knowledge regarding psychiatric symptoms and recovery; knowledge about the recovery process; the understanding of what is important for recovery; and the understanding of the challenges and responsibility in recovery, respectively. Subsequent CFA suggested good fit to the data. Good convergent validity and understandable internal consistency reliability were also observed.ConclusionsThe Japanese 16-item RKI revealed reasonable factorial validity, good convergent validity, and understandable internal consistency reliability among mental health professionals. Japanese cultural settings seemed to influence the four-factor structure in the present study. It can be used for future study in Japan, while future large-scale research is required to ensure robust verification.

Factors related to recovery knowledge and attitudes among professionals in mental health in Japan

“…High scores indicate a better knowledge base. However, a previous study verified that the 16‐item Japanese version of RKI exhibited better reliability (Cronbach's α = .77) and validity (goodness of fit [GFI] = .93; adjusted AGI [AGFI] = .90; confirmatory fit index [CFI] = .91; root mean square error of approximation = .053) (Chiba et al, ). Thus, the total score of 16‐item RKI was used in this study.…”

“…We conducted a secondary analysis on data from a self‐administered questionnaire survey that was conducted from February to March 2012 (Chiba et al, , ). In the initial study, the sample included mental health professionals from two psychiatric hospitals in the Kanto region and 56 psychiatric clinics and community service agencies in Tokyo, Japan.…”

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

“…Additionally, programs aimed toward recovery similar to those developed in the west, such as Assertive Community Treatment, Wellness Recovery Action Plan, Illness Management and Recovery, and Recovery College are widely practiced in Japan [10][11][12][13][14]. For the evaluation of practice, the psychometric properties of the Japanese version of recovery-related scales in which service users measure their personal recovery and service providers measure their recovery knowledge and attitude have been verified [15][16][17][18][19][20]. As described above, programs including personal recovery are being used.…”
