Psychometric properties of Social Safeness and Pleasure Scale (SSPS)

Researches have shown that social safeness is a transdiagnostic vulnerability factor in a wide range of psychological problems. Therefore it seems to be necessary that researchers and clinicians consider this component in their investigations. To achieve this, the first step is to prepare an appropriate measure for evaluating this construct. The aim of this study was to investigate the psychometric properties of Persian version of the Social Safeness and Pleasure Scale (SSPS).
Translation-back translation was done to prepare the Persian version of SSPS. A convenience sample of 521 students from three universities in Tehran was examined in 2015-2016. To investigate the validity of the scale, construct validity (via exploratory factor analysis and confirmatory factor analysis) and divergent validity were used. Therefore, the total sample was split randomly to two samples of 300 subjects (for exploratory factor analysis) and 221 subjects (for confirmatory factor analysis). For investigation of reliability, Cronbach's alpha and test-retest reliability coefficient were used.
Exploratory factor analysis of SSPS’s items showed a single factor structure and confirmatory factor analysis confirmed this structure. Cronbach's alpha was 0.91 and test- retest reliability coefficient was 0.82. The divergent validity was verified by calculating the correlation between SSPS and IIP, BDI-II, and SPIN.
It seems that the Persian version of the Social Safeness and Pleasure Scale has adequate validity and reliability.
