2.2. Schools and Participants
RECRUITMENT
Schools were eligible to participate if they met the following criteria: (1) public school offering 6th, 7th, and 8th grades with at least 65 students per grade; (2) located in Maricopa County, AZ; (3) having a Hispanic student population of at least 60%; and (4) receiving Title I funds from the federal government to assist in meeting students’ educational needs. A total of 84 schools met the eligibility criteria; of those, the first 36 schools with decreasing numbers of student enrollment were then clustered by geographical location. Within each of the 12 geographic clusters (3 schools per cluster), each school was assigned a random number generated by Excel. Performed by the study methodologist, it was determined a priori that within each cluster, the school with the lowest random number would be assigned to the FPNG+ intervention, next lowest to FPNG, and the third lowest to RAD. This sequence was repeated for all 12 clusters and 36 schools. The allocation sequence was concealed from all other study team members until interventions were assigned. Eligible schools were contacted by a community partner to ask if they were willing to offer the assigned program to their students’ parents at their facilities. Schools were no longer contacted once the team had enrolled 6 schools for a given study arm, or until study implementation ended due to the COVID-19 pandemic. A total of 16 local middle schools were part of the study: 6 were randomized to the FPNG+ intervention, 5 to the original FPNG intervention, and 5 to the RAD control intervention. Of the 16 schools, 3 schools joined the study for the first time in the spring of 2020 and are not included in the present analysis because the team was unable to deliver the full intervention and collect T2 or T3 data after February 2020 due to the COVID-19 pandemic. Therefore, the current analysis includes data from 13 schools (n = 5 for FPNG+; n = 3 for FPNG Original; n = 5 for RAD) and only includes data from the participants in the cohorts that received the full intervention.Participating dyads were eligible if parents were 18 years or older, their adolescent child was enrolled in 6th, 7th, or 8th grade of a participating school at the time of recruitment, and were, self-reported, of Hispanic/Latinx descent. Participating adults provided written informed consent and parental permission for their adolescent child to take part in the study; participating adolescents provided written assent prior to participation. Adolescent participation was not required for parents to enroll in the study. Based on school enrollment data during the open recruitment phases of the study, there were a total of 14,349 students/parent dyads in participating schools. This yielded 496 eligible parents who were enrolled in the study, of which 344 provided parental consent and adolescent assent to participate. Of those, 105 dyads were excluded from this analysis due to COVID-19-related cancellations of the intervention programs, leaving data from 239 dyads for the present analysis. Complete follow-up data is available for 205 dyads at T2 and for 203 dyads at T3. The CONSORT flow diagram (
