Non-specialist mental health interventions serve as a potential solution to reduce the mental healthcare gap in low- and middle-income countries, such as Sri Lanka. However, contextual factors often influence their effective implementation, reflecting a research-to-practice gap. This study, using a qualitative, participatory approach with local mental health workers (n=9) and potential service users (n=11), identifies anticipated barriers and facilitators to implementing these interventions while also exploring alternative strategies for reducing the mental healthcare gap in this context. Perceived barriers include concerns about effectiveness, acceptance and feasibility in the implementation of non-specialist mental health interventions (theme 1). The participants' overall perception that these interventions are a beneficial strategy for reducing the mental healthcare gap was identified as a facilitating factor for implementation (theme 2). Further facilitators relate to important non-specialist characteristics (theme 3), including desirable traits and occupational backgrounds that may aid in increasing the acceptance of this cadre. Other suggestions relate to facilitating the reach, intervention acceptance and feasibility (theme 4). This study offers valuable insights to enhance the implementation process of non-specialist mental health interventions in low-and middle-income countries such as Sri Lanka.
