Optimization of the CoPsoQ questionnaire in a population of Archipelago of Azores

WithF.O. Nunes, A. Gaspar da Silva

The present study analyzes the internal consistency and reliability of an already widely disseminated and nationally and internationally validated questionnaire applied to a selected population of the Autonomous Region of Azores. The questionnaire consists of the 119 items in the long-length version of the Portuguese adaptation of the Copenhagen Psychosocial Questionnaire (CoPsoQ). Applying factor analysis techniques to the results of the 234 questionnaires collected, an optimized questionnaire was constructed with 54 items that, besides its ease of application, also presents better cost-benefit and reliability in the majority of item’s scales/dimensions.
