A Validation Study of the COPSOQ III Greek Questionnaire for Assessing Psychosocial Factors in the Workplace

Over the past two decades, the Copenhagen Psychosocial Questionnaire (COPSOQ) has been established as a valid instrument to measure psychosocial stress at work. Currently, the COPSOQ international network is responsible for monitoring and improving the COPSOQ. In 2019, a new questionnaire was published, and the Greek version is now being validated. The aim of the current study was to assess the reliability and validity of the psychometric properties of the Greek long version of the Copenhagen Psychosocial Questionnaire III (COPSOQ-III-GR).

The measurement qualities of the Greek COPSOQ III have been explored in accordance with the usual requirements of a validation study, as defined by DIN EN ISO 10075-3. A sample of observations from 2189 participants surveyed with the COPSOQ in Greece was used to validate the current version with appropriate statistical analyses. Exploratory factor analysis was used to assess the statistical relationships for many scales.

With its 108 items and 40 scales, the Greek COPSOQ III includes all internationally validated psychosocial workplace factors that remain comparable (~72%) with the COPSOQ III German version content. In addition to the primary results, congruence with widely used theoretical approaches such as the demand-control (-support) model (DCM) or the job demands-resources model (JDR) is generally satisfactory. In summary, our validation study for the Greek COPSOQ III version showed adequate reliability and validity, which is in line with the findings of the COPSOQ III questionnaire from other European countries, and it is also compatible with the validation of the German COPSOQ III. Our regression analysis revealed that 34 psychosocial workplace factors (34 "context" scales) could adequately predict the scores of the satisfactory and health scales (6 "outcome" scales). The analysis also revealed the top five predictors (context variables) for each of the six "effect" scales (outcome variables).

With the launch of COPSOQ III in Greece, current and new workplace psychosocial aspects could be explored, since COPSOQ III (GR) appears to be a valid and reliable instrument for enterprise research and risk assessment.
