Experimental Design

Experimental Design
We will recruit interested and eligible parents of middle-school children in Ecatepec de Morelos, Mexico, and offer them SH+. We will recruit parent-child dyads from local middle schools and randomize treatment eligibility by dyad.

Eligible households will be invited to participate in Self Help Plus (SH+), a transdiagnostic, WHO-designed, 5-week course of group therapy based on a type of Cognitive Behavioral Therapy. Our target sample size is 1,000 parent-child dyads, but we will try to enroll more dyads depending on eligibility and interest in the participating schools. The children will not receive any treatment.

We will measure parental outcomes both at baseline and at the end of the intervention. We will measure children's outcomes at endline only.
