Abstract

BACKGROUND:

The purpose of this study was to investigate the influence of locus of control on adherence to a treatment regimen among hypertensive patients.

METHODS:

The participants were 100 previously diagnosed hypertensive patients drawn from the Ituku-Ozalla University of Nigeria teaching hospital, using a purposive sampling technique. All participants were individually administered the Wallston, Wallston & Devellis (1978), Multidimensional Health Locus of Control (MHLC) scale, and Drug Adherence Questionaire (DAQ) by the researchers. A one-way factorial design and analysis of variance with unequal sample sizes were used to analyze the data.

RESULTS:

Internally-oriented patients adhered more to their treatment regimen than externally-oriented patients, F(1.98) = 18.2 (P < 0.01).

CONCLUSION:

Locus of control should be taken into consideration in the review of treatment packages for patients. This is because the efficacy of drugs depends to a reasonable extent on adherence to the schedule. If drugs are not taken as prescribed, their potency may be affected or wrongly assessed.

KEYWORDS:
