| Exercise:
Stages of Change - Continuous Measure Please use the following definition of exercise when answering these
questions:
Regular Exercise is any planned physical activity (e.g.,
brisk walking, aerobics, jogging, bicycling, swimming, rowing, etc.) performed to increase
physical fitness. Such activity should be performed 3 to 5 times per week
for 20-60 minutes per session. Exercise does not have to be painful to be
effective but should be done at a level that increases your breathing rate and causes you
to break a sweat.
Please enter the number in the box that indicates how strongly you agree or disagree

1 = Strongly Disagree
2 = Disagree
3 = Undecided
4 = Agree
5 = Strongly Agree

Dissertation Abstract
This project set out to continue the development and refinement of
the URICA-E2, an instrument to measure stage of change for regular exercise based on the
Transtheoretical Model of Behavior Change. In Study One, the URICA-E2 which is a
proportionate measure of stage of change, was analyzed using Principal Component Analysis
and refined into a 24-item instrument capturing not five, but six stages of change:
Precontemplation-Non Believer (PCN), Precontemplation-Believer (PCB), Contemplation (C),
Preparation (P), Action (A), and Maintenance (M). The standardized scale scores from the
URICA-E2 were clustered and seven profiles were found. They duplicated the six stages and
added a seventh which was tentatively named Ambivalent (ABV). In Study Two, a series of
models were tested using Confirmatory Factor Analysis in order to better understand the
relationship between the stage constructs. Nine models were tested: two types of
simplex, four types of circumplex, and three types of punctuated equilibrium. A circumplex
model, where the strongest relationships were found among the stages which are adjacent,
alternate, and opposite, was found to nearly mimic the exercise data. This supports
the very common experience of people frequently relapsing and frequently restarting
regular exercise. Study Three sought confirmation of the URICA-E2 by validating it against
three short form staging algorithms, the Decisional Balance instrument, the Confidence
instrument, and a measure of hours of exercise. The Single Question Algorithm was found to
outperform the other algorithms. The profiles of the URICA-E2 demonstrated the classic
crossover of pros with cons around the Preparation stage. Confidence was seen to rise
across the profiles. In conclusion, it was found that the URICA-E2 is a multipurpose tool,
well worth the effort required to use it. What other instrument could give you six stages
of change, seven profiles, and show a circumplex to be the best way to describe the
relationship between the stages? For the times that demand a shorter staging instrument,
the Single Question Algorithm has proved to be an instrument of choice. It has the
advantage of simplicity, ease of administration, and it performs as well as if not better
than its five question counterpart.
