Stressors at work are classified, according to Kalimo (1980) and Cooper (1976) in six broad categories: role within organisation, intrinsic stressors, interpersonal problems, work climate, career, social context. The 40-item Factors of Stress Questionnaire has been proposed as a screening instrument for causes of stress at work. The factor structure of the questionnaire was evaluated in 371 health care workers. Internal reliability analysis was also conducted. The Factor Analysis, according to the Kaiser rule to drop all components with eigenvalues under 1.0, gave nine principal components, with a 58% cumulative variance explained. However, most of these components had poor comprehensibility. The first component was significantly related to most of the items. The questionnaire showed good reliability (Cronbach's alpha = 0.93).
根据卡里莫（1980年）和库珀（1976年）的研究，工作压力源可分为六大类：组织内角色、内在压力源、人际问题、工作氛围、职业、社会环境。已提出40项工作压力因素问卷作为工作压力成因的筛查工具。对371名医护人员的问卷因素结构进行了评估，并进行了内部信度分析。根据凯泽法则，剔除特征值小于1.0的所有成分进行因子分析，得到9个主成分，累计方差解释率为58%。然而，这些成分大多难以理解。第一个成分与大多数项目显著相关。该问卷显示出良好的信度（克朗巴哈系数=0.93）。
