Self-efficacy as a mediator of the relationship between subjective well-being and general health of military cadets.

The objective of this study is to investigate the role of self-efficacy beliefs as a mediator of the relationship between the subjective well-being and general health of military cadets (police and firefighters). For this study, 228 cadets participated, the majority being Military Police officer candidates (65%), male (79%), between 17 and 34 years of age (99%), and unmarried (74%). They responded to questionnaires on general health (GHQ-12), perceived general self-efficacy, to the multiple scales that cover subjective well-being, and demographic questions.

The 12-item General Health Questionnaire (GHQ-12) is a widely used screening instrument. One- and two-factor structures have been identified in some countries. In Brazil, the best factor structure is still unclear.
