Maintenance of Change in the
Active-for-Life Initiative

Background: There is a notable gap in translating efficacious interventions to community-based
organizations. Further, physical activity interventions have been less successful in promot-
ing longer-term maintenance.
Purpose: This study examined 6-month maintenance of improvements seen in Active for Life (AFL),
a translational research initiative.
Methods: Participants from seven of 12 AFL sites enrolled in Years 3 and 4 were surveyed 6 months
after completing the 6-month telephone-based Active Choices program (AC, one site) or
the 20-week or 12-week group-based Active Living Every Day program (ALED, six sites).
Repeated measures analyses controlled for site clustering and covariates. Programs were
implemented from 2003 to 2007 and analysis was conducted in 2009.
Results: For the AC (n=368) and ALED (n=2151) programs, respectively, participants were aged
72.0 and 70.8 years on average, were 70% and 78% non-Hispanic white, and were 72% and
83% women; 46% and 50% returned 6-month follow-up surveys. For AC, improvements
from pre- to post-test were maintained at follow-up for physical activity; satisfaction with
body function (SBF); and BMI. For ALED Year 3, there was a decrease at follow-up for
physical activity and SBF. Body mass index decreased from pretest to follow-up. For ALED
Year 4, increases in physical activity and reductions in BMI were maintained at follow-up.
Satisfaction with body function increased from pretest to 12 weeks post-test, declined at 20
weeks, and was maintained at follow-up.
Conclusions: Improvements were generally maintained at the 6-month follow-up. When behavioral
decay occurred, follow-up values remained more favorable than at pretest. Given the broad
reach of this translational initiative, the results suggest the viability of evidence-based
programming as an effective public health practice.

Introduction
A
lthough substantial progress has been made in
testing behaviorally based interventions to pro-
mote physical activity, two major issues plague the
field. First, the public health impact of most empirically
validated interventions is never known because efficacious
interventions are rarely adapted for widespread transla-
tion to community-based organizations.
1,2
Second, inter-
ventions have been less successful in promoting longer-
term maintenance of behavior change.
3–5
Interventions
that are integrated into community-based programs could
promote maintenance of physical activity behavior
change because they are accessible to large numbers of
community residents.
Active for Life (AFL) was a translational research
initiative that successfully increased moderate-intensity
physical activity in midlife and older adults.

This
study examined whether these improvements were main-
tained 6 months post-intervention. It was hypothesized
that intervention effects would be greatest from pretest
to immediate post-test but would be maintained, de-
spite some decay, at follow-up.

In AFL, Active
Choices (AC) was a 6-month physical activity program deliv-
ered through one face-to-face meeting and up to eight brief
telephone counseling calls.
8 –10
Active Living Every Day
(ALED) was a 20-week physical activity program delivered
