Investigation of the reliability and validity of the Japanese Deliberate Self-Harm Inventory

[Abstract] The concept of self-harm behavior and the range of included behaviors are varied ; therefore, a scale that can quantitatively ascertain specific behaviors is necessary to accumulate empirical data on self-harm behavior. The objectives of this study were to create a Japanese version of the Deliberate Self-Harm Inventory (DSHI) , a self-administered scale on intentional self-harm behavior, and to evaluate its reliability and validity. Although there were minor issues with its internal consistency, test-retest reliability was sufficiently high, suggesting that the translated scale has test-retest reliability similar to that of the original version. Correlation analysis with existing scales showed that the Japanese version of the DSHI also had convergent and discriminant validity similar to that of the original version.
