“…These observations have also been supported in a nonrandomized study with a small outpatient clinic sample [37]. In contrast to those significant findings, a meta-analysis of the relationship of internal and external LOC with glycemic control among people with diabetes found little to no correlation [38]. Given the variation of need among individuals with diabetes, which likely depends on their history of control, comorbidities and complications, health LOC may be a moving target.…”

PURPOSE Perceptions of control impact outcomes in veterans with chronic disease. The purpose of this study was to examine the association between control orientation and clinical and quality of life (QOL) outcomes in male veterans with type 2 diabetes (T2DM). METHODS Cross-sectional study of 283 male veterans from a primary care clinic in the southeastern US. Health locus of control (LOC) was the main predictor and assessed using the Multidimensional Health Locus of Control Scale. Clinical outcomes were glycosylated hemoglobin A1c (HbA1c), systolic (SBP) and diastolic (DBP) blood pressure, and low-density lipoprotein cholesterol (LDL-C). Physical (PCS) and mental (MCS) health component scores for QOL were assessed using the Veterans RAND 12-Item Health Survey. Unadjusted and adjusted multivariate analyses were performed to assess associations between LOC and outcomes. RESULTS Unadjusted analyses showed internal LOC associated with HbA1c (β=0.036; 95% CI 0.001,0.071), external LOC:powerful others inversely associated with LDL-C (β=−0.794; 95% CI −1.483,−0.104), and external LOC:chance inversely associated with MCS QOL (β=−0.418; 95% CI −0.859,−0.173). These associated remained significant when adjusting for relevant covariates. Adjusted analyses also demonstrated a significant relationship between external LOC:chance and PCS QOL (β=0.308; 95% CI 0.002,0.614). CONCLUSIONS In this sample of male veterans with T2DM, internal LOC was significantly associated with glycemic control, and external was significantly associated with QOL and LDL-C, when adjusting for relevant covariates. Assessments of control orientation should be performed to understand the perceptions of patients, thus better equipping physicians with information to maximize care opportunities for veterans with T2DM.

“…Holding beliefs in external locus of control (health professionals) and internal locus of control can be beneficial: the combination of internal and powerful others locus of control is considered useful: while the patient feels personal responsibility for self-care, there is also a good patient-provider relationship. A recent meta-analysis (Hummer, Vannatta, & Thompson, 2011) reviewing the association between beliefs related to diabetes and adherence to diabetes regimens corroborated these findings. They found that perceived positive relationship with one's physician as well as holding beliefs about personal consequences of adherence were associated with adherence to treatment…”

The purpose of this study is to explore the relationship between glycaemic control, locus of control beliefs, diabetes knowledge and wellbeing in young adults with type 1 diabetes. A cross-sectional study of forty-two young adults (16-25 years) with type 1 diabetes recruited from two diabetes clinics in London. Participants completed postal questionnaires designed for this specific population. Wellbeing was assessed by the W-B12, locus of control by the ADDLoC and diabetes knowledge by the ADKnowl. HbA1c was employed as a measure of glycaemic control. Results indicated that external (health professionals) and internal locus of control beliefs and diabetes knowledge were significantly associated with psychological wellbeing. Patients place high expectations on their practitioners and accordingly, practitioners need to address patients' diabetes knowledge to help them to manage their diabetes effectively and independently. The relationship between internal and external locus of control beliefs, diabetes knowledge and wellbeing indicates the importance of addressing empowerment and self-efficacy in psychoeducation interventions for this client group.

“…In a study by Morowatisharifabad et al (2010), a positive relation was found between internal locus of control and adaptation to diabetes management. No relation was found between the locus of control and metabolic control of diabetes according to some studies (Nugent & Wallston, 2016; Hummer, Vannatta & Thompson, 2011; Bunting & Coates, 2000; Kneckt, Syrjala & Knuuttila, 1999). In a study by Kneckt et al, no relation was found between the locus of control and A1c level.…”

“…Literature shows different research results on the effect of locus of control on metabolic control of diabetes and self-care activities. While some studies support a positive relation between internal locus of control and metabolic control of diabetes, in other studies, no relation was found (Hummer, Vannatta & Thompson, 2011; Bunting & Coates, 2000; Kneckt, Syrjala & Knuuttila, 1999). The findings of this study will contribute to the literature in explaining this effect and the results of this study can be used in planning diabetes education programs.…”

BackgroundPrevious studies have examined the role of individuals’ personal characteristics in diabetes management and used the locus of control theory to assess adherence to a diabetes management regimen. These studies have emphasized that having internal locus of control may be a protective factor in diabetes management.ObjectiveThe purpose of this study is to determine the predictor effect of locus of control on self-care activities and A1c level.MethodThe study is descriptive and relational. Researchers used a Diabetes Self-Care Activities Scale and a Locus of Control Scale to collect data. The study sample consisted of 129 individuals with type 2 diabetes.ResultsThe average score of locus of control of individuals with diabetes was 10.26, and the frequency of self-care activities in the past week was 2.9 days. A weak but statistically significant negative relation was found between the locus of control level and self-care activities of individuals with diabetes, which had no effect on A1c. It was determined that locus of control predicts 19% of self-care activities.ConclusionAccording to the study results, having internal locus of control had positive effects on self-care activities. Training and planning activities to improve internal locus of control can improve diabetes management.
