The Role of Health Locus of Control in Predicting Depression Symptoms in a Sample of Iranian Older Adults with Chronic Diseases.

OBJECTIVE: The purpose of this study was to examine the prediction of depression on a group of Iranian older adults based on components of health locus of control.

METHOD: Sixty-six men and 42 women over the age of 55 were recruited from the retirement clubs in Shiraz, using convenience sampling. The participants completed the research questionnaires including the Geriatric Depression Scale (GDS) and the Multidimensional Health Locus of Control Scale (MHLC).

RESULTS: The findings on health locus of control revealed that the highest score was on internal locus of control followed by God, powerful others and chance. The mean score on depression was on a normal range. Multiple regression analysis showed that two independent variables including internal control (ß = -.32, p < 0.01) and God control (ß = -.20, = p < 0.03) significantly predicted depression. The other components of health locus of control such as chance and powerful others as well as age did not predict depression. Findings also revealed that the independents variables explained 26% of the total variance of depression (R2 = .26, p <0.001).

CONCLUSION: his study provides more support for the application of theory of health locus of control on depression.
