Perceived suicide stigma and associated factors in Chinese college students: Translation and validation of the stigma of suicide attempt scale and the stigma of suicide and suicide survivors scale

This study aims to translate and validate two perceived suicide stigma scales, including the Stigma of Suicide Attempt Scale (STOSA) and the Stigma of Suicide and Suicide Survivor Scale (STOSASS) into Chinese language, examining the factor structure, and assessing the correlation between suicide stigma and a series of variables. After translating and back translating the STOSA and STOSASS, an online survey was administrated to 412 college students in China. These two scales were tested for their dimensionality in a series of confirmatory factor analyses. A series of regression analyses were conducted to examine the factors that are associated with perceived and public suicide stigma, including demographics, psychological distress, suicidality, suicide exposure, and perceived entitativity of suicide ideators, decedents, and survivors. The results showed that the two translated scales, STOSA and STOSASS, were reliable (Cronbach’s α = 0.79~0.83) and valid in Chinese contexts and it can be treated as unidimensional scales. Suicidality, exposure to suicide, and perceived entitativity of suicide-related persons were significantly associated with higher endorsement of public suicide stigma (SOSS Stigma, p < 0.03), but not perceived stigma (STOSA, STOSASS). Higher levels of psychological distress were associated with both higher perceived and public suicide stigma (p < 0.05).
