A systematic review of preventive interventions regarding mental health issues in organizations.

The most recent review of the workplace prevention literature was published two decades ago. Since then, interest has been growing in the business and research communities in preventive workplace interventions. At the same time, there has been an increasing recognition of the complexity of developing workplace interventions. This study's purpose is to assess the literature from 2001 to 2006 using Cottrell's conceptualization to: 1) conduct a systematic review of the most recent literature, 2) describe the preventive psychological interventions for workers, 3) summarize the significant work- and health-related outcomes associated with these interventions, and 4) identify where the significant gaps still exist. Twenty-four studies on primary and secondary interventions regarding mental health issues in organizations were included and analyzed in this systematic review. Eight studies were identified as primary interventions, 14 were identified as secondary interventions, and 2 included both. There was a predominance of studies utilizing skills training. One-third of studies used a combination of individual, group and organization level interventions, most often supported by psychosocial intervention or participatory research. These components brought positive and significant results with regard to work and mental health outcomes to workers.
