Translating the Diabetes Prevention Program to Primary Care:

A Pilot Study

Acknowledging that there is a need for the obese Type 2 diabetics (T2D) to make changes in their lifestyle, Whittemore et al. (2009) decided to do a study to see if there is a need for programs to decrease the incidence of Type 2 diabetes. The article selected is an example of experimental quantitative design. The summary model can be found in the text on pages 112 through 114 in Polit & Beck (2012). There were four Nurse Practitioner (NPs) groups recruited for this study. There were four randomized sites used for the study, two sites, which consisted of lifestyle changes, and two sites enhancing the standard care program (Polit & Beck, 2012). Problem Statement

In the 21st century, T2D has become a health epidemic. The associated health risks that accompany T2D have the cost of healthcare escalating. Research is needed to help find ways to limit the progression of this disease process. Persons of ethnic descent are twice as likely to have an inconsistent risk for developing this disease (Polit & Beck, 2012).

Statement of Purpose

The purpose of this pilot study was to evaluate the interpretation of the improved diabetes prevention program (DPP) with specific changes allowing Nurse Practitioners (NPs) to carry this into their primary care practice (Polit & Beck, 2012).

Research Question and Hypothesis

The research question is will NPs find a way in their primary care practice to reach the T2D population, implement a program to help them change their lifestyle and continue to follow up with care? The hypothesis is the NPs can successfully implement a lifestyle change program for T2D population using goal setting and problem solving techniques (Polit & Beck, 2012).

Study Methods

The study method used was of a mixed design with two phases. First phase was for modifying the protocol for intervention making it easier for the NPs to implement into their practice. Phase two was the clinical trial pilot study, which included a cluster randomization. Repetitive measures were used to assess the reach, execution, and preliminary efficacy in an improved lifestyle program (Polit & Beck, 2012).

Key Findings

NPs lacked motivation is assisting the participants to change and point out that their behavior was inconsistent with their personal goals and values (Polit & Beck, 2012). Significant time needs to be allotted for sessions so participants may discuss psychosocial issues an all aspect of protocol may be completed (Polit & Beck, 2012). The NPs were able to attain the goal of providing pertinent care to ethnic and racial community areas in order to improve health outcomes (Polit & Beck, 2012).

Article Critique


The title explicitly mentions the diabetic population and the study are described as a pilot program. The emphasis of the pilot study is stated in the title translating the diabetes prevention program to primary care (Whittemore et al., 2009).


The abstract thoroughly summarizes the layout of the article, which includes the background, objectives, methods, results, and the discussion (Whittemore et al., 2009). The reach, implementation, and efficacy of the lifestyle change program were the objective of this article (Whittemore et al., 2009). The method was randomly selected at-risk adults chosen to participate in one of two groups; control, or treatment. There was a 70% acceptance to the program (Whittemore et al., 2009).


When beginning to read the article, it is difficult to know if the researcher has omitted the introduction and opted to proceed in researching the problem. The researcher quantified the problem utilizing multiple aspects at one time, including, but not limited to Type 2 diabetes (T2D) healthcare risks and the ethnicity influences and factors of the disease (Whittemore et al., 2009). Evidence has recently...
