Objectives: This study was conducted to examine the psychometric properties of the French versions of the Perceived Stress Scale (PSS) and to compare the appropriateness of the three versions of this scale (14 items, 10 items, or 4 items) in a sample of workers. Materials and Methods: Five hundred and one workers were randomly selected in several occupational health care centers of the North of France during 2010. Participants completed a questionnaire including demographic variables and the PSS. The psychometric properties of this scale were analyzed: internal consistency, factorial structure, and discriminative sensibility. Results: For the PSS-14 and PSS-10, the Exploratory Factor Analysis (EFA) provided a two-factor structure, corresponding to the positively and negatively worded items. Those two factors were significantly correlated (r = 0.43 and 0.50, respectively). For the PSS-4, the EFA yielded a one-factor structure. The reliability was high for all three versions of the PSS (Cronbach’s α values ranged from 0.73 to 0.84). The results concerning the effects of age, gender, marital, parental and occupational statuses showed that the 10-item version had the best discriminative sensibility. Conclusions: The findings confirmed satisfactory psychometric properties of all the three French versions of the PSS. We recommend the use of the PSS-10 in research settings because of its good psychometric properties.

Objectives: Only a few studies have analyzed the health of self-employed workers. This cross-sectional study is the first to compare health status among craftsmen joiners and paid joiners. Material and Methods: Clinical and paraclinical data for self-employed craftsmen and employees were collected by occupational health doctors according to a standardized protocol and compared. Health data and professional status relationships were analyzed by logistic regression. Results: A total of 171 craftsmen and 196 paid workers were included. Craftsmen had more dermatologic pathologies (odds ratio (OR) = 2.67, p < 0.05), ear/nose/throat symptoms (OR = 3.38, p < 0.001), pulmonary symptoms (OR = 2.46, p < 0.05), musculoskeletal symptoms (OR = 3.09, p < 0.001), and abnormal audiogram (OR = 3.50, p < 0.001). The FEV₁ was significantly lower among craftsmen (p < 0.01), independently of tobacco smoke exposure. Conclusions: This survey highlights a high morbidity rate among self-employed craftsmen, suggesting that among woodworkers, professional status can be a risk factor for health. The preventive medical system for craftsmen has to be rethought to guarantee better safety for this population.
