BackgroundMental health service utilization remains a challenge in developing countries, with numerous barriers affecting access to care. Albeit data suggest poor utilization of mental health services in the Bolgatanga Municipality in Ghana, no studies have explored the barriers to the utilization of mental health services. Therefore, this study explored the perspectives of family caregivers, service providers, and mental health service administrators on the barriers to mental health service utilization in the Bolgatanga Municipality, Ghana.MethodsA qualitative descriptive design was employed for the study. Nineteen participants were purposively sampled from two hospitals including fifteen family caregivers, two service providers, and two mental health administrators. Data were collected through individual in-depth interviews using a semi-structured interview guide. Audio-recorded interviews were transcribed verbatim and thematically analyzed using NVivo 12 pro software.ResultsFive main themes emerged including individual-level barriers, interpersonal barriers, community-level barriers, organizational-level barriers, and policy-level barriers. At the individual level, lack of insight, poor treatment compliance, and financial challenges were prominent barriers. Interpersonal barriers included family pressure influenced by cultural and spiritual beliefs. At the community level, stigma and mental health illiteracy were identified as significant barriers. At the organizational level, barriers encompassed inadequate staffing, limited space, and staff attitudes. Policy-level barriers included the neglect of mental health in policies and the non-inclusion of mental health services in the National Health Insurance Scheme.ConclusionThis study highlights the complexity of barriers to mental health service utilization and underscores the need for a comprehensive approach to address them. Collaborative efforts involving healthcare providers, policymakers, communities, and families are essential to mitigate these barriers. It is imperative to consider these barriers when developing strategies to improve the utilization of mental health services in Ghana.
