Background: Mental illness stigma acts as a major barrier that may results in disparities in access, treatment, and outcome. Scales designed to assess stigmatising attitudes towards those with mental illness among health care providers are necessary to evaluate programs designed to reduce that stigma. Objectives: The aim of this study was to evaluate the internal reliability and external validity of the Opening Minds Scale for Health Care Providers (OMS-HC)) among health staff in a Tertiary Healthcare Centre.Materials and Method: 308 participants from the Jos University Teaching Hospital answered a self-administered questionnaire, i.e Community Attitudes towards the Mentally Ill (CAMI) scale, and the opening mind scale for Health care providers (OMS-HC). Coefficient alphas were computed to obtain internal consistency estimates of reliability for the CAMI subscales and OMS-HC. Correlations of OMS-HC scores with CAMI scores were calculated and compared to evaluate concurrent validity. Results: The result showed internal consistency of OMS-HC, The cronbach’s alpha was 0.985 reflecting high level of internal consistency within the 20 item scale. The concurrent validity scores were: 0.983 and 0.990 for Pearson and spearman correlation coefficient respectively (P<0.001). Conclusion: The findings from our study showed a good and strong correlation between OMS-HC and the chosen gold standard (CAMI). Hence OMS is valid and reliable, suitable for clinical and research purposes.
