Feasibility and efficacy of the Great Leaders Active StudentS (GLASS) program on children's physical activity and object control skill competency: A non-randomised trial.


OBJECTIVES:This study aimed to assess the feasibility and efficacy of the Great Leaders Active StudentS (GLASS) program, a school-based peer-led physical activity and object control skill intervention. DESIGN:The study employed a quasi-experimental design. METHODS:The study was conducted in two elementary schools, one intervention and one comparison, in Newcastle, New South Wales (NSW), Australia from April to June 2015 (N=224 students). Peer leaders (n=20) in the intervention school received training to deliver two 30-min object control skill sessions per week to students in Kindergarten, Grades 1 and 2 (5-8 years, n=83) over one school term (10 weeks). The primary outcome was pedometer assessed physical activity during school hours. Secondary outcomes included students' object control skill competency and peers' leadership self-efficacy and teacher ratings of peers' leadership skills. RESULTS:Almost all (19/20) GLASS sessions were delivered by peer leaders who reported high acceptability of the program. The treatment-by-time interaction for students' physical activity during school hours was not significant (p=0.313). The intervention effect on students' overall object control skills was statistically significant (mean difference 5.8 (95% CI 4.1, 7.4; p<0.001)). Teacher-rated peer leadership significantly improved (0.70; 95% CI 0.38-1.01); p<.001)). CONCLUSIONS:The GLASS program was found to be both feasible and acceptable. The intervention also resulted in improvements in students' overall object control skills as well as teacher-rated peers' leadership behaviours. Future fully powered trials using peer leaders to deliver fundamental movement skill (FMS) programs are warranted.
