Evaluation Of The Effectiveness Of A Diabetes Managment Training Program For Unlicensed Assistive Personnel In Schools, Elaine M. Gomer

Master's Projects

This study evaluated the diabetes management-training program for unlicensed assistive personnel (UAP). The purpose of the program was to prepare UAP to recognize and respond to the health care needs of students diagnosed with diabetes mellitus. Twenty UAP participated. Teaching strategies were based on Albert Bandura' s social learning theory~ Two instruments were administered before and after the program. One was a 1 0-question survey addressing self-efficacy; the other was a 10 question multiple-choice test measuring knowledge of diabetes. Results of paired t tests indicate consistent and significant improvement in both perceptions of self-efficacy and knowledge (p < .05). This program provides a framework for school nurses training UAP that assist in the health care of students with diabetes. It is important that school nurses capitalize on the contribution that informed confident UAP might contribute to the provision of safe quality care to students with diabetes.

The Impact Of The Chip Program On Depression And Well-Being: A Pilot Study, Carmen Diehl Thieszen

Loma Linda University Electronic Theses, Dissertations & Projects

Reliable studies have demonstrated that intensive and comprehensive lifestyle changes can reduce coronary risk, which, in turn, can prevent, postpone, and reverse coronary heart disease (CHD) and affect its underlying atherosclerotic lesions. These well-established studies have focused their interventions on moderating biophysical risk factors. In the past 10 years, however, burgeoning research is supporting the idea that psychological factors, such as depression and well-being, are also important CHD risk factors. Little research has addressed, in a non-subjective way, how an intervention program focused on modifying biophysical risk factors may influence psychological factors. Using the Beck Depression Inventory-Short Form, the Dartmouth …
