Abstract

The purpose of this study was to evaluate the psychometric properties of three versions of the Perceived Stress Scale (PSS; © American Sociological Association) in adults who had survived the death of a family member or significant other by suicide. Reliability and validity were examined. Exploratory factor analysis was conducted to assess dimensionality of the underlying constructs. All three versions of the PSS demonstrated acceptable reliability. Two shorter versions retained good psychometric properties and demonstrated convergent and concurrent validity with measures of posttraumatic stress symptoms and mental health quality of life. Factor analysis provided further evidence of their usefulness as brief and valid measures of perceived stress in acutely bereaved adult survivors of suicide. In a sub-sample of closely related survivors, the psychometric properties of the 4-item version of the PSS were retained.
