The psycho-educational model was implemented in three phases during a workshop and then for three months in practice by university lecturers. A purposive sample of university lecturers was applied. The effectiveness of the psycho-educational model was evaluated during and directly after the workshop, 1 week after the workshop and 3 months journal entries. Final evaluation was in a focus group after 3 months of implementation of the model in the workplace.Results: The participating university lecturers found the implementation of the psycho-educational model, as a conceptual framework of reference to constructively manage experiences of aggression, effective, helpful and important.
