Burns and Grove (2009) describe sampling as “a process of selecting subjects, events, behavior, or elements for participation in a study” (2009). In this study, the researchers obtained a sample of the population to be studied by using the self selection method. The participants were selected from a specific geographic area and adults affected by DMT2 in ambulatory care setting were identified via door to door calling. Creatinine level was tested on the participants who agreed to be a part of the study due to the possibility of renal damage (Rule et al, 2004 as cited in Gallegos, ovalle-Berumen, & Gomez-Meza, 2006). Those who had a creatinine level above 1.5 ml/dl could not participate. The experimental group had 29 adults while the comparison had 28. Only 25 adults completed the entire study in the experimental group while a number of 20 participants made it through in the comparison group. The research used convenient sampling in both groups nevertheless assignment of the subjects to each group was random. The sample size does not truly represent the population in the study. There were three different settings utilized in this study. Educational activities took place in nursing facilities for the experimental group and the counselors were able to go the participants’ homes or talk to them via telephone. For the comparison group, the researchers relied on the participants monthly visits with their primary care provider to check blood glucose level to collect data for the study. In this study, the population was clearly identified as well as the inclusion and exclusion criteria. A nonprobability sampling was utilized. The creatinine level was checked before the participant took part in the study. Refusal rate was not included ... ... middle of paper ... was a significant difference between the two groups and that difference was present in the second, fourth, and fifth measurement. The second hypothesis indicated that up to 60% of the subjects in the experimental group would achieve HbA1c values within the range of acceptable control. The effect of the intervention, the binomial test was used and p=.50 in each of the five measurement. Improvement was already noticeable by the second measurement. In fact, in one measurement at time 5, the subjects with moderate to good blood glucose control reached 60%. The answer about the other variables was obtained through the use of a multivariate analysis which revealed that self-care agency, barriers and adaptation to DMT2, and one interaction had a major impact on the self-care activities scores and on HbA1c (Gallegos, ovalle-Berumen, & Gomez-Meza, 2006).
