The purpose of the study was to develop a diabetes locus of control scale and to assess its validity and reliability. Factor analysis of the items was conducted utilizing varimax orthogonal rotation. Three factors were identified representing Internal (6 items), Chance (6 items) and Powerful Others (6 items) orientations. The subscales were internally consistent, Cronbach alphas were .75, .77 and .72 for the Internal, Chance, and Powerful Others scales. Test-retest reliabilities were for the…

Validation of a new multidimensional health locus of control scale (form c) in asthma research
Findings indicate that asthmatics with higher “Powerful Others” locus of control perceived they had a better quality of doctor-patient relationship; the opposite was found for those withHigher “Chance” scores.
Structure and Correlates of Diabetes-Specific Locus of Control
The concept of DLC appears to have explanatory power in accounting for health outcomes, especially when internal DLC measures of autonomy and self-blame are differentiated.
Reliability and Validity of a Measure of Perceived Diabetes and Dietary Competence in African American Women With Type 2 Diabetes
This study provides initial support for the internal reliability and validity of a perceived diabetes and dietary competence measure developed to assess a person's sense of confidence and perceived behavioral control in Diabetes and dietary self-management.
Relationships between Locus of Control and Adherence to Diabetes Regimen.
Findings suggest that interventions aimed at improving internal locus of control may improve adherence to diabetes regimen but different diabetic patients have different attribution styles and interventional programs to enhance diabetes self-care will be more successful if patient's locu of control is addressed.
Locus of Control and Metabolic Control of Diabetes
There may be a weak correlation between powerful others and chance LOC with the metabolic control of diabetes, but the use of LOC as a means of designing diabetes care can be discarded as this random effects meta-analysis found no significant correlation with effectiveness of diabetes control in adult patients.
Relationships between locus of control and adherence to diabetes regimen in a sample of Iranians
Findings suggest that interventions aimed at improving internal locus of control may improve adherence to diabetes regimen but different diabetic patients have different attribution styles and interventional programs to enhance diabetes self-care will be more successful if patient's locu of control is addressed.
The findings of this study indicate that there was a significant effect of self-concept and locus of health control on the quality of life of people with diabetes.
Associations between type of treatment and illness-specific locus of control in type 1 diabetes patients
High powerful others locus of control was associated with low diabetes-related knowledge and poor glycaemic control in Type I diabetes patients undergoing either conventional therapy, intensified conventional therapy or continuous subcutaneous insulin infusion.
Multidimensional Health Locus of Control: Comments on the Construct and its Measurement
It is argued that MHLC has supplied health psychology with essential insights and has offered a great deal of intellectual stimulation, but for some applications, different constructs might be more promising, in particular when it comes to predicting health behavior change.


Development of the Multidimensional Health Locus of Control (MHLC) Scales
The development of the Multidimensional Health Locus of Control scales is described. Scales have been developed to tap beliefs that the source of reinforcements for health-related behaviors is
Health Beliefs, Compliance, and Control of Diabetes Mellitus
Examination of health beliefs of 93 male diabetic patients correlated their beliefs with behavioral and physiologic measures of compliance and suggested that improving attitudes about care may be a means of directly influencing control of the disease.
Some Problems and Misconceptions Related to the Construct of Internal Versus External Control of Reinforcement
Research involving perceived internal versus external control of reinforcement as a personality variable has been expanding at a rapid rate. It seems clear that for some investigators there are
Understanding and Enhancing Patient Compliance with Diabetic Regimens
A comprehensive conceptual framework in the context of learning theory to explain patient compliance and to derive approaches for enhancing compliance is proposed and the health belief model (HBM) is expanded to include the concept of perceived self-efficacy.
Compliance to Self-Monitoring of Blood Glucose: A Marked-Item Technique Compared with Self-Report
Objective measures such as the marked-item technique described in this article should be used to assess compliance to SMBG and behavioral strategies to improve compliance should be developed.
Activism and Powerful Others: Distinctions within the Concept of Internal-External Control
Summary Some studies report that activists are Internals, while others claim they are Externals, holding a belief in chance, fate, and powerful others. Three new scales were constructed in order to
Evaluating the Costs and Benefits of Outpatient Diabetes Education and Nutrition Counseling
It appears that some of the programs actually increased, rather than decreased, health care expenditures, and it is suggested that the rationale for education and nutritional services be based on improved health status.
Examination by treatment groups showed that patients with retinopathy whose disease was controlled with insulin had significantly higher levels of glycosylated haemoglobin compared with those without this complication, and patients whose disease is controlled with orally administered hypoglycaemic agents did not show this difference.
Cross‐validation of a short form of the Marlowe‐Crowne Social Desirability Scale
This research is a cross-validation and extension of Reynolds' (1982) short form of the Marlowe-Crowne Social Desirability Scale, using three separate groups (N = 233). Unlike Reynolds, the present
Multidimensional Locus of Control in Prison Inmates1
This study examined public offenders' generalized expectancies of control as they relate to length of time in prison and behavior within the institution, in order to demonstrate the usefulness of a
