BACKGROUND: The information processing demands associated with behavioral self-management of diabetes are extensive. Pairing personal digital assistant (PDA)-based self-monitoring with a behavioral self-management intervention may improve adherence and patient outcomes. METHODS: ENHANCE is a randomized controlled trial to test an intervention designed to improve regimen adherence in adults with type 2 diabetes. The intervention, based on Social Cognitive Theory (SCT), is paired with PDA-based self-monitoring. In this paper we describe the: (a) manner in which PDA-based self-monitoring is integrated within the SCT-based intervention, (b) feasibility and acceptability of PDA-based dietary self-monitoring, and (c) issues encountered in teaching participants to self-monitor using a PDA. RESULTS: During the first 30 months of this 5-year study, 232 participants were screened and 151 were randomized. To date, 6 cohorts have completed the study. The retention rate is 85% (n=129). Of those randomized to the intervention (n=74) and completing the study (n=61), 88% reported understanding the usefulness of PDA-monitoring, 85% reported ease in entering foods into the device, 70% reported ease in interpreting feedback graphs, and 82% indicated that they would continue to use the PDA for self-monitoring after the study concluded. Assuming 3 meals per day, participants entered an average of 58% of their meals in their PDA, and 43% were entered assuming 4 meals per day. If we eliminate from the analysis those individuals who entered less than 10% of their expected meals (n=12), the average rate of self-monitoring was 69% assuming 3 meals per day, and 52% assuming 4 meals per day. CONCLUSIONS: PDA-based dietary monitoring is perceived by participants to be useful and acceptable. The approach used to instruct participants in use of the PDA and lessons learned are discussed. PDA technology shows promise as a tool for assisting those with type 2 diabetes in their efforts to manage their disease.  

PURPOSE: The purpose of this study was to examine the impact of family and friends on the management of persons with diabetes and their willingness to be involved in a culturally tailored program. METHODS: This qualitative study was based within a larger quasi-experimental study that focused on the impact of a culturally tailored group intervention compared with individual standard diabetes education on the outcomes of self-management and glycemic control among rural African Americans with type 2 diabetes. Twenty-one participants were randomly assigned to an individual education group or a culturally tailored intervention group. Family members/peers (n = 6) attended invited group sessions to obtain information about diabetes and family/peer support. The facilitator of the invited group sessions used a guide to help with group discussions. The investigators used an iterative approach to enhance the examination of the responses from the discussion guide, thus identifying recurring themes within the participants' responses. RESULTS: The data revealed that family and friends made a difference in the diabetes management of individuals with diabetes. Although family and friends may have been helpful at times, they also created moments of problems and an environment that made it more difficult to care for diabetes. The data also revealed that diabetes is hard to manage and control. Participants reported that taking medications and being aware of types of foods to keep a well-maintained glucose level were often challenging. CONCLUSIONS: These findings confirm that family and peers greatly influence diabetes management among rural African Americans. The study's results will help health care providers understand the importance of involving family members and friends in the treatment and diabetes management of individuals with type 2 diabetes, particularly within rural African American communities where resources are limited.

Organizational culture consists of the deep underlying assumptions, beliefs, and values that are shared by members of the organization and typically operate unconsciously. The four organizational culture traits of the Denison Organizational Culture Model (DOCM) are characteristics of organizational effectiveness, which include adaptability, involvement, consistency, and mission. Effective organizations demonstrate high levels of the four cultural traits which reflect their ability to balance the dynamic tension between the need for stability and the need for flexibility within the organization. The Denison Organizational Culture Survey (DOCS) is a measurement tool that was founded on the theoretical framework of the DOCM, and in the field of business, is one of the most commonly used tools for measuring organizational culture. The DOCS offers a promising approach to operationalizing and measuring the link between organizational culture and organizational effectiveness in the context of nursing units.

African Americans are at greater risk for hypertension than are other ethnic groups. This study examined relationships among hypertension, stress, and depression among 120 urban African American parents and grandparents. This study is a secondary analysis of a larger nurse-managed randomized clinical trial testing the effectiveness of a telemonitoring intervention. Baseline data used in analyses, with the exception of medication compliance, were collected at 3 months' follow-up. Health indicators, perceived stress, and social support were examined to determine their relationship with depressive symptoms. A total of 48% of the variance in depressive symptomology was explained by perceived stress and support. Health indicators including average systolic blood pressure explained 21% of the variance in depressive symptomology The regression analysis using average diastolic blood pressure explained 26% of the variance in depressive symptomology Based on study results, African Americans should be assessed for perceived stress and social support to alleviate depressive symptomology.
