Abstract

Suicide-related disclosure is an important component of identifying individuals at risk for suicide. However, no standardized measures exist to assess the degree to which individuals have disclosed suicide-related experiences. Therefore, the present study tested the psychometric properties of the Self-Harm and Suicide Disclosure Scale. A sample of 142 individuals, predominantly female and Caucasian, with ages ranging from 18-77 who had experienced suicidal ideation or behavior in their lifetime completed online surveys. A Rasch model analysis was used to test the item and individual separation and reliability and model fit of the instrument's use for disclosure to both family and nonfamily members. Analyses indicated strong item separation and reliability. Items were removed to improve model fit, resulting in two revised instruments.

FINDINGS indicate the Revised Suicide and Self-Harm Disclosure Scales are appropriate measures for assessing the depth of suicide-related disclosure. Future studies should attempt to replicate these findings with a more diverse sample.
