Measurement of deliberate self-harm: Preliminary data on the deliberate self-harm inventory

Deliberate self-harm has recently begun to receive more systematic attention from clinical researchers. However, there remains a general lack of consensus as to how to define and measure this important clinical construct. There is still no standardized, empirically validated measure of deliberate self-harm, making it more difficult for research in this area to advance. The present paper provides an integrative, conceptual definition of deliberate self-harm as well as preliminary psychometric data on a newly developed measure of self-harm, the Deliberate Self-Harm Inventory (DSHI). One hundred and fifty participants from undergraduate psychology courses completed research packets consisting of the DSHI and other measures, and 93 of these participants completed the DSHI again after an interval of 2-4 weeks (M = 3.3 weeks). Preliminary findings indicate that the DSHI has high internal consistency; adequate construct, convergent, and discriminant validity; and adequate test-retest reliability.
