The maltreatment of people with mental illness in Ghana's traditional and faith-based healing centres, including shackling, flogging, and forced fasting, has been documented by numerous sources. Such treatment is potentially traumatising and may exacerbate mental health problems. Despite widespread use, few studies have focused on experiences and characteristics of people who seek traditional healing for mental illness or healers' perspectives treatment of these conditions.

Purposeful sampling was used to recruit 82 individuals who were treated in healing centres and 40 traditional healers; all took part in semi-structured interviews. Those treated were asked about experiences in centres and assessed for prior trauma exposure, posttraumatic stress, and functional impairment. Healers were asked about beliefs and practices related to the treatment of mental illness.

Individuals treated in centres and healers generally believed that mental illness has a spiritual cause. Approximately 30.5% of those treated in centres were exposed to maltreatment; despite this, half would return. Individuals with a history of trauma were more likely to report maltreatment in the centre and had higher symptoms of posttraumatic stress. Most participants had impaired functioning. Healers who used practices like shackling believed they were necessary. Most healers were willing to collaborate with the official health structure.

Results provide insight into the treatment of mental illness by traditional healers in Ghana and the need for trauma-informed mental health services. Findings also highlight the importance of considering cultural beliefs when attempting to implement mental health interventions in the region.
