Spanish-language Executive Function Intervention for Children With Autism and/or ADHD

The goal of this clinical trial is to learn whether the Spanish-language version of Unstuck and On Target (SL-Unstuck), an executive functioning (EF) intervention, is feasible, acceptable, and effective for Spanish-speaking caregivers and their neurodivergent children (ages 8-11) in the U.S.. The main questions it aims to answer are: * Is SL-Unstuck acceptable to Spanish-speaking caregivers and children? * Does SL-Unstuck improve child EF, caregiver EF knowledge, and caregiver strain? Researchers will compare families randomly assigned to immediate SL-Unstuck versus waitlist control to see if participating in the intervention improves EF and family outcomes. Participants will: * Attend 8 weekly SL-Unstuck sessions at a clinic (parallel child and caregiver groups) * Complete pre- and post-intervention assessments on child EF, caregiver strain, and satisfaction * Participate in a focus group to share feedback on the intervention
