Abstract
The legal code 15b of the LPOR explains the duty to evaluate all risks that cannot be avoided, such as those working conditions that can generate risks for health and safety. Thus, the assessment of these risks is a complex topic. Among the number of measurement instruments, a method that is extensively employed in Spain is the CoPsoQ-ISTAS 21 method, or ISTAS 21. This questionnaire of psychosocial risks measurement has been translated to many languages, and there is evidence on questionnaire validity and reliability in these versions. However, the factorial structure of the CoPsoQ has not been tested with the totality of items and dimensions of the questionnaire, neither in the Spanish version, nor in other versions, including the original Danish one. The aim of this study is to offer evidence on the factorial structure of the CoPsoQ-ISTAS 21, together with the convergent and discriminant validity of these underlying constructs. The worker population of a Spanish public university, 1200 workers, was invited to participate in the study. The response rate was 45.33%. For confirmatory purposes, item parceling was employed. Afterwards, a structural equation modeling was estimated. The model tested was completely a priori, and thus, results were strictly confirmatory. The correlations between factors were too many to be shown in detail, but enclosed important information, that is, they showed the convergent-discriminant validity of the 20 dimensions for measuring the four superior constructs theoretically proposed. Results of this study are based on a sample of university workers, not general workers population. This is, therefore, a first step in the study of the confirmatory structure of the scale.
