The impact that this research has been exploring is the effect that psychiatric social work practices within communities has in alleviating challenges that result from mental illnesses, as faced by individuals with mental health conditions, within Kwara State, in the Republic of Nigeria. The research design adopted is a cross-sectional descriptive design; hence, the research used a questionnaire to collect significant quantitative data from service users, social workers, and stakeholders within communities who are actively involved in psychiatric social work practices. The results clearly show that community-based psychiatric social work has contributed greatly to a reduction in stigma, difficulties, and problems that come with mental illness, improved accessibility, and facilitated the inclusion of clients within a social setting. Among the identified practices, counseling, as well as advocacy, played a critical part in ensuring that clients with mental health problems are included within society, compared with other practices used within the sector. This research brings to the forefront the critical importance of community psychiatric social work practice in regard to the improvement of the quality of life of individuals who suffer from mental illness, within a resource-poor state such as Kwara State. The findings have significant implications with respect to enhancing community psychiatric practice within the state, particularly for individuals who suffer from mental illness. The findings support a small but significant body of literature within a Nigerian setting.
