The purpose of this study is to understand how self-efficacy associated with the quality life approach at work influence the management of the adaptation of human and organizational change to prevent psychosocial risks. The data were collected base on a biographical approach to the personal and professional history of 10 workers who have been exposed to psychosocial risks. It results that high or low self-efficacy protects them from the occurrence of psychosocial risks, or exposes them, and that managers' management style strengthens this self-efficacy. These results indicate that human functioning must be understood as the result of a dynamic and ongoing interaction between cognitions, behaviours and environmental circumstances.
