Program evaluation process evaluation example (CDC Framework style) – Chronic
Disease Self-Management Program
The Chronic Disease Self-Management Program (CDSMP) is a proven tool for helping
people with chronic disease enhance their health and well-being. The focus
of the six week class is on teaching participants to set reachable goals and
then achieve them. Programs in the Section of Chronic Disease Prevention
and Health Promotion (CDPHP) worked together to bring this program to Alaska,
starting with a training of leaders and master trainers in January 2006.
This example is one component of the project evaluation conducted by CDPHP in 2007.
CDC Framework, step 1 – Engage Stakeholders
In this step, the people who would be affected by the program
evaluation are identified, along with people who are in a position to use
it to improve the program or act to continue progress toward the program’s goals.
The stakeholders include CDSMP course leaders and master trainers, their
sponsoring agencies, and participants in their classes. The focus of
this component of the CDSMP project evaluation is on the course leaders,
who were asked to distribute participant evaluation forms, collect some
information (age group, sex, chronic disease) from participants, and send
completed packets to CDPHP.
CDC Framework, step 2 – Describe the program
Program evaluation depends on a careful, specific description
of the program and the relationship between the program and its intended affect.
CDSMP is a series of six two-hour sessions presented over six weeks. The
ideal group size is 10 to 14 participants. Each session includes
presentations on common concerns for people with a chronic disease such as
managing pain and fatigue, healthy eating, and working with a health care team,
and provides time for developing and discussing the success of participants’
self-determined action plans for changing a behavior. Each week,
participants choose a buddy from the class; the buddies agree to check in
with each other between sessions to find out about and support progress toward
each other’s action plans.
A simple logic for this project is:
CDC Framework, step 3 – Focus the design
In this step, attention shifts to what is wanted from the
program evaluation. Questions to consider include: Generally, why
are you evaluating? Who will use the evaluation results, and how will
they be used? What data collection strategy(ies) will you use?
The purposes of this program evaluation are to support project accountability
and to provide constructive feedback to course leaders, master trainers and
the agencies sponsoring CDSMP.
The specific evaluation question for this example is: Is CDSMP being
implemented as planned? To answer this question, data were collected
from participants using a questionnaire.
CDC Framework, step 4 – Gather evidence
Now, with all of the background information from the first three
steps, comes the question of exactly what information is needed for meeting
the evaluation needs identified in step 3.
CDSMP sessions are guided by a pair of leaders, who use a script. The
script is very self-contained, which means that leaders do not need to have
a medical background to be effective. Since leaders agree to follow
the script when they sign an agreement that allows them to lead CDSMP
sessions, CDPHP decided that the presentation of material did not need to
be assessed. Instead, CDPHP decided to use between-session support
provided by the buddies as an indicator for the quality of CDSMP implementation.
CDPHP developed questionnaires for participants as part of the program
evaluation materials. After completing participant feed-back
questionnaires, which are distributed at the end of the last session,
participants put them into an envelope that is then closed before it is
returned to the leader, who then bundles it with other participant and
class information and sends the whole package to CDPHP.
The questionnaire asks participants to rate their contact with their
buddy(ies) from none (1) to frequent (10). Between 3/1/06 and
12/31/06, forty-six participants completed the feed-back questionnaires,
with a mean, or average, of 4.7 for this question, indicating a minimal
use of the buddy system.
CDC Framework, step 5 – Justify conclusions
Once data have been collected, they must be analyzed and interpreted.
This is a disappointing result, since it suggests that these CDSMP participants
missed important support for their behavior change efforts.
There are several limitations that prevent a more conclusive interpretation.
They include:
- Lack of a comparison. Since there are no program standards for
the buddy system aspect of CDSMP, there is no way to determine if the
4.7 result is lower or higher than or the same as other programs.
- These data could be biased. They are self-reported, and answers could
be affected by poor memories (which might reduce the rating) or by a
desire to please (which might increase the rating) or other factors.
- These data were only collected from people who were at the last
session. There is no way to know if the respondents were more or
less likely to have benefited from the buddy system than participants
who did not complete a questionnaire.
- Only 46 people completed a survey, which means that very low or very
high ratings by one or two individuals could have a substantial impact
on the average.
CDC Framework, step 6 – Lessons learned
The final step in the Framework is similar to the
Action Plan component of the Results Accountability process.
It involves distributing the results and engaging stakeholders in using
the results to move forward.
CDPHP wrote and distributed an evaluation report, including this finding,
to all CDSMP master trainers and leaders in Alaska. A report on this
program, including all process evaluation findings, was also published as
the first CDPHP Chronicle in September, 2007.
As a result of drafting this excerpt from the program evaluation, CDPHP
has identified the need to take further action. CDPHP will encourage
master trainers to emphasize the added strength that the buddy system can
lend to the success of CDSMP in their leader training sessions.
CDPHP will also use publication of the Chronicle to directly
encourage leaders to promote buddy interaction.
Results from the first year of CDSMP program evaluation will be used as a
baseline and compared with subsequent periods.
