Multidimensional health locus of control as partial predictor of serum phosphorus in chronic hemodialysis

The Multidimensional Health Locus of Control Scale was administered to 137 chronic hemodialysis outpatients in a survey designed to examine the relationship of these scores to serum phosphorus, a laboratory indicator of dietary compliance in end-stage renal disease. In a multiple regression analysis, scores on the Powerful Others Locus of Control subscale accounted for 8.9% of the variance in serum phosphorus. Discussion includes a tentative explanation of the findings and limitations of the design.
