Hybrid Effectiveness-Implementation Trial of a School Clinician Training and Psychosocial ADHD/ODD Intervention Program Adapted for Schools Across Mexico

Aim 1) Test the effectiveness and implementation of the CLS-A-FUERTE school clinician training and ADHD/ODD intervention program adapted for schools across Mexico. It is predicted: H1) School clinicians will engage in training and implement chosen intervention components with fidelity H2) Teachers and/or families will engage in chosen intervention components and adhere to the strategies H3) Students receiving the CLS-A-FUERTE intervention will show greater improvements in ADHD/ODD symptoms and associated impairment compared to students receiving school services as usual Aim 2) Evaluate mechanisms of sustained intervention change. It is predicted: H4) Improvements in parenting behaviors will mediate sustained intervention effects H5) Improvements in teacher and/or school clinician competency will mediate intervention effects Aim 3) Identify CLS-A-FUERTE maintenance barriers and facilitators. It is predicted that sustained intervention effects and continuation of program activities at follow-up will relate to: H6) Program feasibility (i.e., cost estimates) and acceptability (i.e., participant satisfaction) H7) Characteristics of participating schools and school context factors Aim 4) Expand research capacity to a novel university setting. It is predicted that emerging investigators will: H8) Complete clinical research coursework and produce deliverables (i.e., presentations, papers, grants) H9) Show improved EBT skills, research capacity and culture ratings, and competency as program trainers
