The purpose was to examine the perspectives of mental health stakeholders as a means to guide the adaptation of evidence-based treatments. The Mental Health System Ecological (MHSE) model was used to organize therapist, administrator, and parent perspectives gathered using qualitative methods. The MHSE model posits the influences of client-level, provider-level, intervention-specific, service delivery, organizational, and service system characteristics on implementation. Focus groups and interviews were conducted with community mental health stakeholders and included parents, therapists, and administrators (N = 21). Participants included 11 primarily Caucasian (90.48%) female participants, ranging in ages between 31 and 57 years. Data were analyzed according to the MHSE model. Frequency counts were tabulated for each theme and stakeholder group differences were determined using the Mann-Whitney test. Stakeholder groups mentioned needs at each level of the MHSE model. Stakeholder group differences most notably emerged with child and family themes, which included complexity of mental health issues, parenting differences, and family stressors. Stakeholders identified challenges for optimal mental health services for children across multiple levels of an ecological model. Implications of the findings are discussed, including the continued relevance of adapting mental health interventions by increasing their flexible application across multiple target problems and the promise of partnership approaches.
