Collaborative Life Skills (CLS) was developed by a UCSF research team as an intervention for children from five to 12 years with symptoms of attention deficit hyperactivity disorder (ADHD). The team then translated and adapted their program to apply it to Latino families in California. Dr. Haack will extend the study, collaborating with the Faculty of Psychology of the Autonomous University of Sinaloa (UAS) to implement in public schools of Culiacán, Mexico.
