Replicating ¡Cuídate!: 6-Month Impact Findings of a Randomized Controlled Trial

Objectives. To test whether iCuidate!, a program culturally adapted for Hispanic youths, affects sexual risk behavior.Methods. We evaluated 3 replications of iCuidate! in California, Arizona, and Massachusetts in a randomized controlled trial (registry no. NCT02540304) in which 2169 primarily Hispanic participants were randomly assigned to an intervention (n = 1326) or a control (n = 870) group. Youths were surveyed at baseline (September 2012–April 2014) and 6 months postbaseline (March 2013–October 2014). We estimated pooled and subgroup impacts using a regression framework with baseline covariates to increase statistical precision (1216 youths analyzed in the treatment group, 806 analyzed in the control group).Results. We found no impacts on the study’s primary outcomes of recent sexual activity or recent unprotected sexual activity. However, iCuidate! improved knowledge (10%–20% increase; P < .001), attitudes (effect size = .24; P < .001), and skills (effect size = .14; P = .002). Exploratory subgroup...
