Verifying the Reliability and Validity of the Japanese Version of the Recovery Self-Assessment Revised Scale for Persons in Recovery

Abstract

The Recovery Self-Assessment Revised (RSA-R) is a scale for measuring service recovery orientation. This study examined the factorial and concurrent validity, internal consistency, and retest reliability of the Japanese version of the RSA-R for persons in recovery. Factor analysis revealed a four-factor model with CFI = 0.86 and RMSEA = 0.065. RSA-R’s total score was significantly higher than those of the Herth Hope Index (ρ = 0.390; p < 0.01) and Client Satisfaction Questionnaire-8 (ρ = 0.612; p < 0.01). The factor scores were also significantly correlated with both scales. The Cronbach’s alpha for the overall scale was 0.94. The weighted kappa coefficients for the retest method showed moderate or better agreement for 22 items. Finally, the ICCs for all factor and total scores exceeded 0.85. In summary, the Japanese version of the RSA-R has a four-factor structure with insufficient factorial validity, good concurrent validity, internal consistency, and retest reliability.
