The Copenhagen Psychosocial Questionnaire—a tool for the assessment and improvement of the psychosocial work environment

The aim of this article is to present the Copenhagen Psychosocial Questionnaire (COPSOQ), a questionnaire developed in three different lengths for assessing psychosocial factors at work, stress, and the well-being of employees and some personality factors. The purpose of the COPSOQ concept is to improve and facilitate research, as well as practical interventions at workplaces.

The development of the questionnaire was based on a survey of a representative sample of 1858 Danish employees aged 20-59 years. The response rate was 62%; 49% were women. Altogether 145 questions from some international and Danish questionnaires and 20 self-developed questions were tested with factor analyses, analyses of internal reliability, and analyses of response patterns.
