Development of a short version of the suicide intervention response inventory

Abstract

A Japanese version of the Suicide Intervention Response Inventory (SIRI-J) had been developed, but needed improvement especially with respect to the number of items. This study was designed to develop and evaluate a short version of the SIRI-J (SIRI-JS). Study 1 used factor analysis, which revealed that the SIRIJ included two components. On the basis of these results, we extracted five items from each component, added three items to represent practical crisis-intervention situations, and drafted the SIRI-JS with 13 items. We also confirmed a strong correlation between the original subscales and those of the short version. Study 2 reconfirmed the validity and reliability of the new measure. In summary, we demonstrated that the SIRI-JS is suitable for assessing the effects of suicide-prevention training.
