摘要：Perceived Stress Scale (PSQ) adaptation is a measuring tool of perceived stress and evaluation of its psychometric properties, on a population-based survey (Greece). Sample N = 1318 of people has anonymously completed the PSQ, comparing it to the Perceived Stress Scale (PSS) and Depressive, Anxiety and Stress Scale (DASS-21). The factor analysis, has shown that the PSQ includes five main factors (Overload, Worries, Joy, Tension/Fatigue, Harassment), which explain the 54.28% of the phenomenon variance. The Cronbach alpha index was 0.9 approaching the respective reliability factor at the original validation (alpha > 0.9). The test-retest reliability was highly statistically significant with an alpha = +0.86, close to the results of the original validation (r = 0.82). The criterion validity has shown high correlation with the PSS (r = 0.737), plus the fact that the results of the correlation with the DSS-21 (r = 0.597) were satisfactory. The satisfactory results, as it concerns the psychometric properties of the PSQ, make the questionnaire an appropriate measuring tool of the perceived stress of the Greek population.
