Occupational stress interventions were discussed. The discussion considered the rationale for conducting occupational stress interventions, the types of intervention strategies for preventing occupational stress, and whether or not stress interventions are really effective. The fact that chronic health problems related to occupational stress represent one of the fastest growing occupational health problems indicates that there is a need for occupational stress interventions. Stress prevention strategies can be viewed as having a three tier or level structure: primary, secondary, and tertiary. Primary intervention strategies are based on redesigning jobs and making organizational changes. Secondary interventions generally involve efforts to help employees modify or control their appraisal of stressful situations. Tertiary intervention strategies are designed to help employees cope more effectively with their reactions to stressful situations. These typically include some sort of assistance program, such as offering counseling for alcohol related problems. With regard to the question of whether stress intervention programs really work, it was noted that a universal solution to job stress is unlikely to be found, primarily because most stress problems are endogenous to a specific organization and usually require solutions that are unique to that organization. Intervention processes, however, could be generic and effective regardless of the nature and type of organization, especially if they include the workers or worker groups in all phases of the process.
