Girls on the Move Intervention
The purpose of this school-based trial is to test the efficacy of an intervention to increase
moderate to vigorous physical activity (MVPA) among middle school girls. The 17-week "Girls
on the Move" (GOTM) intervention has 3 components. Two individual-level components occurring
during school hours include: (1) two face-to-face motivational, individually tailored
counseling sessions with a school nurse, and (2) an interactive Internet-based session during
which each girl receives motivational, individually tailored feedback messages (at 9 weeks).
A group-level component, 90-minute Physical Activity (PA) Club provides an important venue
after school that includes activities to assist girls in establishing a behavioral pattern of
MVPA. The control condition will complete data collection activities and receive their usual
school offerings.
The investigators hypothesize that immediately post-intervention, minutes of MVPA will be
greater by 16 min./wk. in the intervention than control group; At 9 months post-intervention
follow-up, minutes of MVPA will be greater in the intervention than control group; and
immediately post-intervention, cardiovascular (CV) fitness will be higher and body mass index
(BMI) and percent body fat will be lower in the intervention than control group.

Our 17-week "Girls on the Move" (GOTM) intervention for middle school girls applies the
Health Promotion Model (HPM) and Self-Determination Theory (SDT) and has 3 components. Two
individual-level components occurring during school hours include: (1) two face-to-face
motivational, individually tailored counseling sessions with a school nurse (occurring at
baseline and near 17 wks.), and (2) an interactive Internet-based session during which each
girl receives motivational, individually tailored feedback messages (at 9 wks.). A
group-level component, 90-min. PA Club, led by PA instructors (e.g., individuals from
community; teachers, including physical education (PE); and sports team coaches) provides an
important venue after school that includes MVPAs (requested by girls in pilot) to assist
girls in establishing a behavioral pattern of MVPA. The control condition will complete data
collection activities and receive their usual school offerings.
The purpose of this school-based group randomized trial (GRT) is to evaluate the efficacy of
the comprehensive GOTM intervention to increase middle school girls' min. of MVPA and improve
cardiovascular (CV) fitness, body mass index (BMI), and percent body fat (% BF) immediately
post-intervention (after 17 wks.) and MVPA at 9-mo. follow-up (F/U; 9 mos. after end of
intervention). Secondary analyses will examine if MVPA is mediated by cognitive (e.g.,
perceived benefits of PA, barriers to PA, and PA self-efficacy; social support) and affective
variables (e.g., enjoyment of and motivation for PA).
Based on demographics of the urban schools, we expect a low-SES, mixed-race, predominately
African American, sample. Eight schools will be randomly assigned to the PA intervention (n =
4) or comparison condition (n = 4) in the fall of yrs. 2, 3, and 4 (total N = 8 X 3 = 24
different schools). Sixty-two girls meeting inclusion criteria based on answers to a
screening tool will be recruited in each school during each of the three yrs.
The long-term goal is to increase MVPA as a means to address the high overweight and obesity
prevalence among adolescent girls.

Inclusion Criteria:

- Available for follow-up (9 mos. after intervention ends)
- Agree to random assignment
- Able to read, understand, and speak English.
Exclusion Criteria:
