Predictive influence of perceived disease severity in combination with perceived benefits and barriers to the dietary control behavior of type 2 diabetic patients
Abstract:
Due to its increasing impact on morbidity and mortality rates, diabetes
mellitus has become a significant global healthcare issue. The etiology stems from a
number of inappropriate dietary control behaviors. This research had the objectives of
assessing the level of perceived severity, benefits and barriers to dietary control and
dietary control behavior in type 2 diabetic patients and, to examine the power of
predicting variables toward dietary control behavior. The sample comprised 265 type
2 diabetic patients who received treatment at the Diabetes Mellitus Clinic of
Ongkharak Hospital in the province of Nakhon Nayok. The data were collected
through questionnaires which were then analyzed by descriptive statistics and ordinary
multiple regression.
The results showed that the overall mean score of type 2 diabetic patients’
perceived severity was at a high level (Mean = 48.48, S.D. = 6.91) while the overall
mean score of the perceived benefits of dietary control was also at a high level (Mean
= 86.06, S.D. = 9.25) and the overall mean score of perceived barriers on dietary
control was at a moderate level (Mean = 33.43, S.D. = 7.66). Finally, the overall mean
score of dietary control behavior was at always performed level (Mean = 87.30, S.D. =
8.37). The results of ordinary multiple regression analysis revealed that perceived
severity, benefits and barriers to dietary control were able to predict dietary control
behavior in type 2 diabetic patients by 10.4 percent at the statistically significant level
of 0.001. It indicated, therefore, that perceived barriers to dietary control may explain
the greatest alterations of dietary control behavior.
Based on these findings, it is recommended that nurses search for a nursing
practice guideline in order to dispel the barriers to dietary control and help diabetic
patients to manage these barriers while promoting continued good dietary control
behavior.
