The ILO's SOLVE programme is based on the recognition of the interdependent relationships between psychosocial factors and other health-related behaviours and their underlying causes in the workplace (work organization, working conditions, labour relations). It deals with the prevention of work-related stressors (both work-place stress and economic stressors), alcohol and drug abuse, violence (both physical and psychological), the prevention of HIV/AIDS, as well as the promotion of tobacco-free workplaces and health lifestyles, including good eating, sleeping and exercise habits. The programme promotes the design of enterprise level policies and intervention programmes to improve working conditions and reduce work-related stress from an occupational safety and health (OSH) perspective by incorporating psychosocial hazards into the risk assessment and risk management strategy, involving both employers and workers through bipartite OSH committees at the workplace level. This Training of Trainers course has been planned for those who want to become instructors of the SOLVE methodology and includes the contents of a regular course SOLVE as well as the sessions to improve the teaching skills of participants for delivery of the instructional package.
