Locus of control and health: a review of the literature.

Locus of control, an individual difference construct from social learning theory, has shown some promise in predicting and explaining specific health-related behaviors. Research is reviewed on the utility of the locus of control construct in understanding smoking reduction, birth control utilization, weight loss, information-seeking, adherence to medication regimens, and other health or sick-role behaviors. Implications for health educators are presented.

Attitude to Health

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 primarily internal, a matter of chance, or under the control of powerful others. These scales are based on earlier work with a general Health Locus of Control Scale, which, in turn, was developed from Rotter's social learning theory. Equivalent forms of the scales are presented along with initial internal consistency and validity data. Possible means of utilizing these scales are provided.

Adult

The relationship between health beliefs, adherence, and metabolic control of diabetes.

There is evidence that an individual's health beliefs influence performance of health behaviors. The purpose of this study was to determine whether health beliefs in persons with diabetes could be modified during a clinical education program and whether the health beliefs were related to adherence to self-care instructions and metabolic control of diabetes. Health beliefs and HbA1c were measured at baseline in 189 adult outpatients with diabetes. Diabetes educators then attempted to modify health beliefs that were not conducive to positive health behaviors. Following education, some health beliefs were modified in a positive direction. Modest, but statistically significant increases in perceived severity of diabetes, perceived ability to carry out recommended behaviors, and perceived benefits of treatment were observed. Although HbA1c improved significantly in a subgroup of patients, this improvement could not be directly associated with any health belief or with self-reported adherence by the measures used in this study.

Adolescent

A role-playing simulation approach toward studying nurses' decisions to listen to patients.

To test a methodology that used role-playing responses by nurses to simulated patient disclosures, a three-part investigation was carried out at Vanderbilt University, Nashville, Tennessee. Four simulated patients-with diagnoses of diabetes mellitus, alcoholism with bleeding ulcer, ulcerative colitis, and cancer of the large intestine-tape recorded 20- to 30-second segments on 12 topics pertaining to their illness. Six topics dealt with the patients' physical problems; six with psychological aspects of the problems. In the tests for nurses' willingness both to listen and to pass along information to the next nurse, the 48 tape-recorded segments of patient information were played for 16 volunteer nurses in a laboratory set up for the purpose. Although the nurses had an option of listening or preparing a medication, they were expected to listen to at least 16 of the 48 segments. Following this, they were asked to tape record a report on the patient for the nurse who would follow them. The nurses, on average, listened to 29 of the 48 segments. The diabetic patient was listened to least; the cancer and the colitis patients each received a similar amounts of attention. The nurses gave substantial amounts of information as well as interpretive data about the patients so that the methodology seemed to prove that nurses could become sufficiently involved in a simulated patient setting.

Communication

Increasing nurses' person-centeredness.

In a two-phased study, two samples of registered nurses listened to audiotaped disclosure statements from simulated patients and responded to each statement "in as helpful a manner as possible." Their responses were judged for degree of "person-centeredness." Nurses in sample one (N=24) received no intervention between the two phases of the study; nurses in sample two (N=20), after completing phase I, listened to a brief message designed to enhance the helpfulness of their responses. No differences were found for the phase I person-centeredness scores; the nurses who received the intervention showed significant improvement in their degree of person-centeredness as compared to those who did not receive the intervention. Implications of these results are discussed.
