1 fs7 fc0 sc0 ls0 ws11">be required to encourage girls to provide social support for
physical activity for each other. We determined that they pre-
ferred a longer program however, we were not able to deter-
mine whether they would have liked more face-to-face sessions
and/or an extended period of time to engage with the website,
however, future studies should consider integrating both the
face-to-face and online component to encourage compliance,
monitor use and trouble shoot to maximize the intervention
dose and potentially impact on physical activity behaviour.
That is, engagement with the website may have been greater if
the face-to-face component used some time to encourage, clari-
fy and motivate the girls to use the website in conjunction with
the face-to-face activities. GRASP-IT recruitment at both
schools was initially successful; however, strategies to address
compliance for the collection of physical activity data is an
issue to be further addressed in future studies (Neumark-
Sztainer et al., 2003; Schneider et al., 2007).
Conclusion
This is the first study that has attempted to engage older ado-
lescent girls to increase their physical activity behaviour using
the social networking site Facebook. We recommend that future
programs targeting older adolescent girls could include an in-
crease in the length of time for face-to-face sessions to maxi-
mize outcomes given the girls preference for this medium and
the possible investigation of other more popular sites that may
be more desirable for adolescent girls to engage and enjoy
while supporting each other to be physically active. The inter-
net is clearly an emerging area for engaging the youth of today
with a high use of technology on their agenda for social, educa-
tional and entertainment pursuits. Interventions need to em-
brace this technologically evolving world and consider innova-
tive ways to engage older adolescent girls in physical activity.
The availability of computer access with internet is increasing
and advancing technology in schools will give many adolescent
girls access to internet support, both during schools hours and
out of school hours and this in turn may potentially benefit their
health through the use of programs such as GRASP-IT.
