Identification of Psychosocial Risk Factors in Working in Confined Spaces: preparation of the questionnaire

Abstract Objective This study aimed to develop and validate the content of a questionnaire for identifying psychosocial risk factors in the performance of confined spaces workers, since so far there is no questionnaire available to access this context. Method This methodological study was developed from a literature review between 2010 and 2019 and semi-structured interviews with 50 workers who work in confined spaces, resulting in items that made up the initial version of the instrument. Results Participants in the questionnaire’s content validation process were 18 professionals working in confined spaces and 22 expert judges.

There were 22 items remained unchanged and six new ones were included, totaling 45 items with a good content validity index.
