Stigma of Suicide Attempt (STOSA) scale and Stigma of Suicide and Suicide Survivor (STOSASS) scale: Two new assessment tools

This study aimed at validating two new assessment tools, the Stigma of Suicide Attempt (STOSA) scale and the Stigma of Suicide and Suicide Survivor (STOSASS) scale. The Devaluation-Discrimination scale of Link et al. was translated into Italian and adapted to measure stigma towards suicidal behavior. Both scales were administered to a mixed sample including members of the general population (n=282), patients with a mental disorder (n=113), suicide attempters (n=57) and people who had lost a significant other to suicide (n=75). Reliability of the scales was good in terms of both internal coherence and test-retest stability. Factor analysis produced an acceptable solution for the STOSA-scale. Items were distributed into two factors, one grouping items to measure supportive, respectful and caring attitudes, the other factor grouping items oriented towards stigmatizing attitudes and beliefs. The clinical populations were more inclined towards stigmatization of suicide than were people from the general population, who might be less aware of the stigma attached to suicide. The two scales may be helpful to quantify stigma at individual level in order to provide targeted supportive interventions, and at population level to measure changes in the beliefs and attitudes of the general population.
