The World Health Organization (WHO) set a target of task shifting as a means of achieving improved mental health services within the community as a means of tackling the unmet needs of mental health care. Primary health care workers (PHCWs) have been identified as essential to achieving this goal.

This study was to identify attitudes and beliefs of PHCWs on mental illness, and to assess the effect of a mental health training on these attitudes and beliefs.

The attitude towards mental illness (ASMI) scale was administered on 91 PHCWs pre- and post- a 4 day training on mental health to assess change in attitude across 6 domains.

Our findings revealed significant positive change in four domains, namely separatism (p = < 0.001), restrictiveness (p = < 0.001), benevolence (p = p =< 0.001) and stigmatization (p = < 0.001). The changes in stereotyping (p = 0.475) and pessimistic prediction (p = 0.056) domains were not clinically significant.

Primary health care workers’ negative attitude and stigmatizing beliefs can be improved upon via regular enlightenment programmes and training. This can be done at regular intervals
