The current study is a randomized controlled trial to test a novel 10-week climate-based intervention within pre-existing afterschool programs, designed to increase moderate-to-vigorous physical activity (MVPA) in underserved (low-income, minority status) middle school youth by addressing youth social developmental needs. Participants (n = 167; 56% female; 62% Black; 50% overweight/obese) enrolled in 6 middle schools were randomized to either the Connect through PLAY intervention or a wait-list control. Process evaluation measures (i.e., observations of external evaluators; staff surveys) indicated that essential elements were implemented with fidelity, and staff endorsed implementation ease/feasibility and acceptability. Regression analysis demonstrated that participation in the intervention (vs. control) was associated with an increase of 8.17 min of daily accelerometry-measured MVPA (56 min of additional weekly MVPA) at post-intervention controlling for baseline MVPA, school, gender, and weight status. The results provide support for social-motivational climate-based interventions for increasing MVPA in underserved youth that can inform future school-based health initiatives.Trial Registration: NCT03850821:

Climate-based weight loss interventions, or those that foster a nurturing family environment, address important ecological influences typically ignored by the traditional biomedical treatments. Promoting a climate characterized by positive communication, autonomy support, and parental warmth supports adolescents in making healthy behavioral changes. In addition, encouraging these skills within the family may have additional benefits of improved family functioning and other mental and physical health outcomes. Although several programs have identified essential elements and established the evidence base for the efficacy of these interventions, few have offered resources for the translation of these constructs from theoretical concepts to tangible practice. This paper provides strategies and resources utilized in the Families Improving Together (FIT) for weight loss randomized controlled trial to create a warm, supportive climate characterized by positive communication within the parent-child relationship. Detailed descriptions of how Project FIT emphasized these constructs through facilitator training, intervention curriculum, and process evaluation are provided as a resource for clinical and community interventions. Researchers are encouraged to provide resources to promote translation of evidence-based interventions for programs aiming to utilize a positive climate-based family approach for lifestyle modification.

BACKGROUND: Interventions that incorporate behavioral skills training and parental involvement have been effective for promoting weight loss among middle and upper class youth; however, few studies have produced similar weight loss effects in underserved ethnic minority youth. PURPOSE: This study examined whether online program exposure (in both an online tailored intervention and an online health education comparison program) predicted greater retention among African American youth and their parents in the Families Improving Together (FIT) for Weight Loss trial. METHODS: Parent-adolescent dyads (N = 125) were randomized to either an online tailored intervention program (n = 63) or an online health education comparison program (n = 62). Paradata including login data were used to determine the number of sessions viewed (0-8) and the number of minutes spent online per session. Study retention, defined as collection of adolescent anthropometric measures at 6 months postintervention, was the outcome. RESULTS: Logistic regression analyses showed a significant effect for login rate on retention (OR = 1.21, 95% CI [1.04, 1.39]). Total number of sessions viewed, child age, child sex, parent age, and parent sex accounted for 11% of the variance in retention at 6 months post- intervention. Participants who were retained spent a significantly greater number of minutes during each session (M = 12.99, SD = 11.63) than participants who were not retained (M = 7.77, SD = 11.19), t(123) = 2.24, p = .027, d = 0.45. CONCLUSIONS: The use of paradata from online interventions is a novel and feasible approach for examining exposure in web-based interventions and program retention in underserved ethnic minority families.
