Psikiyatri Hemşireliği Dergisi
Objectives: Since stigmatizing people who attempt suicide can have very serious consequences, learning about this form of stigmatization is important. The aim of this study is to examine the reliability and validity of the Turkish version of the Stigma of Suicide Scale (SOSS) with a sample of university students. Methods: The study used a methodological design. Its sample included 1,100 university students. Validity and reliability analyses were done after verifying the scale's linguistic
... 's linguistic equivalence. The scale's applicability and understandability was pilot tested. Test-retest reliability was tested with 100 students. After the linguistic equivalence of the scale was assured, its relevance and reliability analyses were conducted. Results: The intra-class correlation coefficient of the Turkish version of the SOSS was 0.93 (F=15.426, p<0.01), indicating good test-retest reliability (r=0.76-0.87, p<0.001). Exploratory factor analysis found that the SOSS has three factors (stigma, isolation/depression and glorification/ normalization). Its three-factor structure was confirmed by confirmatory factor analysis. Of the 58 items assessed for inclusion on the scale, 3 items (a burden, punishing others and weak) did not load above 0.33 on any factor and were excluded from its final version, leaving 55 items. Its Cronbach's alpha coefficient was 0.90, and factor loading was between 0.36 and 0.69. Analyses showed that each factor structure of the Turkish version of the SOSS had high internal consistency. Conclusion: The current study found that the Turkish version of the SOSS is a relevant and reliable scale for assessing the stigmatizing attitudes towards people who committed suicide. The SOSS is the first attitudes scale designed to directly measure the stigma of suicide in the community.
