Psychosocial Assessment of Transplant Candidates: Inter-rater Reliability and Concurrent Validity of the Japanese Version of the Stanford Integrated Psychosocial Assessment for Transplantation.

BACKGROUND

The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) is a comprehensive instrument developed to provide a standardized, objective, and evidence-based psychosocial evaluation of the main pretransplant psychosocial risk factors that may influence transplant outcomes.

OBJECTIVE

Because established assessment procedures or standardized tools designed to perform pre-solid organ transplant psychosocial evaluation are currently unavailable in Japan, the present study aimed to develop and preliminarily validate the Japanese version of the SIPAT.

METHODS

First, the Japanese version of the SIPAT was developed using standard forward-back-translation procedures. Then, the Japanese versions of the SIPAT and the Japanese version of Psychosocial Assessment of Candidates for Transplant were retrospectively and blindly applied to 107 transplant cases by 4 independent raters.

RESULTS

The interrater reliability of the scores obtained with the Japanese version of the SIPAT was excellent (Pearson's correlation coefficient = 0.86). The concurrent validity of the SIPAT to the Psychosocial Assessment of Candidates for Transplant for each examiner was substantial (Spearman's rank correlation coefficient = -0.66).

CONCLUSION

These findings suggest that the Japanese version of the SIPAT is a promising and reliable instrument. Further research is required to test the predictive validity of the Japanese version of the SIPAT.
