[SUMMARY] The Ministry of Justice in Japan developed and has used new assessment tools for individuals under supervision,referred to as Case Formulation in Probation/Parole（CFP）, based on the Risk-Need-Responsivity（RNR）model, which globally has become the primary model in assessment and intervention for justice-involved individuals. This study examined the inter-rater reliability of the CFP’s dynamic factors, which included seven dynamic risk factors and six dynamic protective and promotive factors corresponding respectively to the seven or six major dynamic risk/need factors identified in the RNR model. Light’s kappa was calculated for the dynamic factors of 25 individuals under supervision to assess the inter-rater reliability of three raters who were or had been probation officers. The results showed that Light’s kappa was 0.90 for all of the dynamic risk factors, 0.91 for all of the dynamic protective and promotive factors, and ranged from 0.77 to 1.00 for 12 of the 13 dynamic factors, indicating adequate to excellent inter-rater reliability. Therefore, this study demonstrated the reliability of the CFP. On the other hand, Light’s kappa was 0.66 for a protective and promotive factor that was contrary to “Procriminal Attitudes.” However, this dynamic factor may be influenced by the raters’ judgment or may be somewhat more subjective than the other dynamic factors, which might have led to the low inter-rater reliability. Suggestions for future research were discussed.
