目的探讨单项应激症状测量的内容、标准和结构效度。这种简明的测量方法在监测工作压力方面会很有用。效度的标准是概念上相近的措施的一致性、与健康和工作特征的相关性的可信性、以及区分组间的能力。第一个数据集来自芬兰邮政，包括健康不佳的症状和精神资源(N=1014)。第二个来自四个北欧国家，包括众所周知的精疲力竭、心理健康、睡眠、活力和乐观程度的验证量表，因此可以研究这些测量之间的趋同性(N=1015)。第三项来自一家金属工厂，包括三项健康指标和四项工作特征(N=773)。第四项代表芬兰工作人口，描述了压力症状的群体差异(N=2156)，并与一项关于工作人口情绪衰竭的研究进行了比较。结果应激症状条目与心理症状条目、睡眠障碍条目、有效幸福感条目有较好的一致性。该量表在理论上与健康指标和心理社会工作特征相关，并根据有效的情绪衰竭量表对性别、年龄组和行业进行区分。结论压力症状条目具有较好的群体分析内容、标准和结构效度。建议在调查研究中用较长的测量心理压力的量表来代替它。
Objectives The objective of the study was to investigate the content, criterion, and construct validity of a single-item measure of stress symptoms. Such a concise measure would be useful in monitoring stress at work. The criteria for validity were convergence with conceptionally close measures, the plausibility of associations with health and work characteristics, and the power to discriminate between groups.Methods Four sets of independent cross-sectional data were used. The first data set, from Finland Post, comprised symptoms of ill health and mental resources (N=1014). The second, from four Nordic countries, included well-known validated scales on exhaustion, mental health, sleep, vitality, and optimism, and therefore the convergence between the measures could be studied (N=1015). The third, from a metal factory, included three indicators of health and four work characteristics (N=773). The fourth, representing the Finnish working population, described group differences in stress symptoms (N=2156) and allowed comparison with a study on emotional exhaustion in the working population. Distributions, correlations, and factor analysis were used for the study.Results The stress-symptoms item converged with items on psychological symptoms and sleep disturbances and with validated measures of well-being. It had theoretically grounded associations with indicators of health and psychosocial work characteristics, and it discriminated between gender and age groups and industrial branches in accordance with the validated emotional exhaustion scale.Conclusions The stress-symptoms item showed satisfactory content, criterion, and construct validity for group-level analysis. It is suggested that the longer scales used to measure psychological stress can be replaced with it in survey research.
