Perceived stress in survivors of suicide: Psychometric properties of the Perceived Stress Scale

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.

Dimensionalidade da escala de estresse percebido (Perceived Stress Scale, PSS-10) em uma amostra de professores

“…As análises fatoriais exploratórias, utilizando matriz de correlações policóricas, método de retenção do minimum rank factor analysis e o critério de retenção fatorial da análise paralela identifi caram uma estrutura unidimensional para a PSS-10, em concordância com estudos prévios (Campo-Arias et al, 2009;Cohen & Williamson, 1988;Luft et al, 2007;Mitchell et al, 2008). Este resultado era esperado, tendo em vista estudos prévios que demonstra-…”

“…Alguns estudos (Campo-Arias, Bustos-Leiton, & Romero--Chaparro, 2009;Cohen & Williamson, 1988;Luft, Sanches, Mazo, & Andrade, 2007;Mitchell, Crane, & Kim, 2008) encontraram, a partir de técnicas exploratórias e confi rmatórias, uma estrutura unifatorial para a escala, conforme postula a base teórica do instrumento (Cohen & Williamsom, 1988), enquanto outros encontraram uma estrutura bifatorial (Leung, Lam, & Chan, 2010;Roberti, Harrington, & Storch, 2010;Wongpakaran & Wongpakaran, 2010). Nestes casos, os fatores são interpretados como estresse (itens positivos) e coping/controle (itens negativos), apresentando níveis de correlações variando entre r = 0,51 e 0,65.…”

Effectiveness of Mindfulness Intervention in Reducing Stress and Burnout for Mental Health Professionals in Singapore

“…" Mitchell, Crane, and Kim (2008) reported that the PSS-10 demonstrated good psychometric properties with adequate convergent and concurrent validity. The Cronbach's alpha of PSS-10 for the present study, measured at pre-intervention, post-intervention and three months later, ranged from 0.81-0.91.…”

Psychometric properties of the perceived stress scale (PSS): measurement invariance between athletes and non-athletes and construct validity

“…The 2-factor PSS-10 reduces 4 items it allows researchers collect data in a short period of time (Shacham, 1983). Although researchers have different arguments regarding dimensionality of PSS (Hewitt, Flett, & Mosher, 1992;Mitchell, Crane & Kim, 2008;Örücü, & Demir, 2009) it is for sure that 2-factor PSS-10 receive better support in sports contexts. The results are consistent with the earlier study by Hewitt and colleagues (Hewitt et al, 1992).…”
