GRI Audio CD
The intervention group received a GRI audio CD that the
researchers created. The GRI audio CD consisted of an
introduction track, two guided relaxation tracks, and 11
guided imagery tracks. The first track explained overalldirections on how to use the CD. Track two consisted of
an imagery controllability and vividness exercise to familiarize
the participant with imagery. The final tracks consisted
of two guided relaxation exercises: Progressive
Muscle Relaxation (PMR, Track 3)19 and deep breathing
(Track 4).
The 11 guided imagery scenarios were based on previous
literature on FOF1,13,14,20,21 and a GRI audio CD created
for older adults to promote physical activity.8 Each
track was 4 to 6 minutes long and was narrated by the first
author or another research assistant trained in relaxation
and guided imagery. An important feature of this CD was
that, as tracks progressed, the activities became more difficult.
For example, earlier tracks consisted of simple activities
around the house, but in later tracks, activities became
more challenging, such as walking on an icy road. The
rationale for this was that, after participants became familiar
with imagery, they would be confident performing the
difficult tasks on later tracks without having a FOF. The
control group audio CD consisted of an introductory
track and two of the same guided relaxation tracks listed
above. Right after listening to a relaxation track, participants
were asked to listen to music of their choice for
5 minutes.
