Barriers and facilitators to integrating mental health and psychosocial support into economic inclusion programming for displaced families in Ecuador.

Background: Displaced populations have increased rates of mental health problems, which have been shown to have a bidirectional relationship with economic insecurity. Despite growing calls globally to integrate mental health and psychosocial support (MHPSS) with economic inclusion (EI) programming, few models exist for practical implementation. We co-developed and piloted the Methods: Fifty displaced families in Quito participated in a pilot trial of the Toolkit between October 2023 and May 2024. Following completion of the trial, we conducted six focus group discussions (n=31; 22 intervention participants, 9 staff) to explore determinants of implementation outcomes, guided by Proctor's Implementation Outcomes Framework and the Consolidated Framework for Implementation Research 2.0. Data were analyzed thematically using a hybrid inductive-deductive approach. Results: Both intervention participants and staff viewed the Toolkit as highly acceptable, appropriate, feasible, and usable, with strong potential for sustainability. Key facilitators included the holistic integration of mental health and livelihood skills, enhanced social network building among displaced families, the Toolkit's standardized yet adaptable structure, and alignment with organizational values and existing activities. Barriers included competing economic demands, childcare responsibilities, transportation costs, limited participation of men and youth, and challenges related to donor reporting indicators. Contextual disruptions-such as Ecuador's 2024 insecurity and energy crisis-posed additional challenges but also demonstrated the Toolkit's adaptability in unstable environments. Conclusions: The
