Detailed evidence for the construct validity of stress questionnaires has been repeatedly demanded. This study aimed to investigate the construct validity of the Perceived Stress Questionnaire (PSQ) in the context of a transactional view of stress.
The examination was based on the PSQ and on standardized quality of life and personality questionnaires. The analyses focused on structural equation modeling. A total of 2552 subjects from a population-based survey were studied.
A transactional model fitted the data. Personality aspects and resources contribute to the total perceived stress. Yet the physical aspects of quality of life receive a comparatively low weighting. The prevalence of perceived stress at a moderate level was estimated to be 14.5%, lowest in the age group>75 years and highest in the 35- to 54-year age group. The prevalence of high stress was 3.1%. The total PSQ-30 score of the general population was 0.30 (S.D.=0.15), slightly higher in women than in men.
We consider the PSQ as a valid instrument for recording subjective perceived stress in the context of a transactional view of stress. The present broad and international database suggests that it needs further investigation in terms of transcultural studies.
人们一再要求提供压力问卷结构效度的详细证据。本研究旨在从压力的交互作用视角调查感知压力问卷（PSQ）的结构效度。
该调查基于PSQ以及标准化的生活质量和人格问卷。分析重点在于结构方程模型。共研究了来自一项基于人群调查的2552名受试者。
一个交互作用模型拟合了数据。人格方面和资源对总体感知压力有影响。然而，生活质量的身体方面权重相对较低。估计中度感知压力的患病率为14.5%，在75岁以上年龄组中最低，在35至54岁年龄组中最高。高压力的患病率为3.1%。普通人群的PSQ - 30总分是0.30（标准差 = 0.15），女性略高于男性。
我们认为在压力的交互作用视角下，PSQ是记录主观感知压力的有效工具。目前广泛的国际数据库表明，它在跨文化研究方面需要进一步调查。
