Target Group: Seventh grade students, both boys and girls
Program Name: N/A
Location: Mid-western USA
Study Objective:
- The purpose of this investigation was to
examine the effectiveness of an eight-session health
promotion/transtheoretical model Internet/video-delivered intervention
to increase physical activity and reduce dietary fat among low-income,
culturally diverse, seventh-grade students .
Study Design: Pre and post test design Intervention or Program:
- In the current study, an eight-session
Blackboard platform-delivered Internet approach with four 2- to 3-min
videos was used in seventh-grade science class.
- The intervention was conducted in a computer laboratory where each student had a computer.
- The Child and Adolescent Activity Log was
used to collect the physical activity data. This 22-item daily log of
activities engaged in by youth required that subjects circle the number
of minutes they spent the previous day in each activity. Subjects
completed the logs for Sunday, Monday, and Tuesday pre- and post test.
- The focus of the intervention was on
strategies appropriate for all stages of change, particularly for those
in pre-contemplation and contemplation stages of the transtheoretical
model.
- Computer-generated tailored feedback based
on stage of change was provided to individual subjects for both physical
activity and dietary fat.
Impact on Physical Activity:
- Intervention students who completed more
than half of the sessions increased moderate/vigorous exercise by an
average of 22 min, compared with a decrease of 46 min for the control
group, p = .05. Those who completed all three sessions (n = 39)
increased activity by 33 min.
Implications for Practitioners:
Use of computer physical activity logs with
appropriate and tailored feedback can be a strong motivational tool.
Support to implement physical activity changes in lifestyle may need to
be ongoing to ensure continued results.
