Logistic regression was used. The adequacy of the model was tested with the Hosmer-Lemeshow goodness of fit test. results: The results indicate that the level of work engagement is similar with that observed in previous studies. Predictors identified in logistic regression are perception of technical factors, location of the job, and personal resources, such as level of effort and overcommitment. discussion: This study identified factors associated with work engagement in a developing country, and adds to the knowledge concerning this new concept in Benin.
