Toward a more valid and reliable health locus of control scale

Abstract
The Multidimensional Health Locus of Control Scale was administered in conjunction with a back care program offered to staff at a psychiatric hospital (N = 82). Validity and reliability of the alternate forms were examined, as was the addition of Forms A and B. The factor structure failed to replicate the original multidimensional construct; hence, suggestions are made to return to the earlier internal/external model and to add the alternate forms to increase reliability.
