Further Psychometric Support for the 10‐Item Version of the Perceived Stress Scale

Abstract

Because of increased stress conditions in college students, updated psychometrics of the Perceived Stress Scale, 10‐item version (PSS‐10; S. Cohen & G. Williamson, 1988) are necessary. Participants were 281 undergraduates at 3 public universities. An exploratory factor analysis revealed a 2‐factor structure measuring Perceived Helplessness and Perceived Self‐Efficacy. Normative results, internal consistencies, and construct validity were supported. The current findings reveal that the PSS‐10 is a reliable and valid instrument for assessment of perceived stress in college students.

“…Respondents were asked to indicate how often they felt a certain way over the last month on a scale from 0 (never) to 4 (very often). This scale has been found to be reliable and valid previously in student populations (Roberti, Harrington & Storch, 2006). In this study, the scale had good internal reliability (Cronbach's α = .85).…”

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

“…Quando os itens da PSS-10 são separados em dois fatores, estes apresentam correlações de 0,51 a 0,69, o que sugere uma moderada covariância entre ambas as dimensões (Reis et al, 2010;Roberti et al, 2010;Wongpakaran & Wongpakaran, 2010). O fator retido apresentou adequada consistência interna, e todos os itens da PSS-10 apresentaram cargas fatoriais de adequada magnitude (> 0,37).…”

“…Os resultados da análise de fatores comuns e da análise paralela permitiram identifi car a dimensionalidade da PSS-10, apontando uma solução unifatorial como a mais representativa dos dados. Entretanto, é importante salientar que a dimensionalidade da PSS-10 não é um consenso na literatura (Leung et al, 2010;Reis et al, 2010;Roberti et al, 2010;Wongpakaran & Wongpakaran, 2010).…”

“…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.…”

“…Possible scores ranged from 0 to 40 with higher scores indicating higher levels of stress. In a 2006 study, the psychometrics of the PSS were updated using 285 college students (Roberti, Harrington, & Storch, 2006), which found the internal consistency of this instrument to be .89 and support for convergent validity with the State-Trait Anxiety Inventory -trait version with strong correlations (.62 to .73). For the purposes of this study, scores on the PSS were treated as a continuous variable so that all levels of perceived stress could be analyzed.…”
