There is limited evidence that contracts can potentially contribute to improving adherence, but there is insufficient evidence from large, good quality studies to routinely recommend contracts for improving adherence to treatment or preventive health regimens.
Increasing return compliance in a tuberculosis detection drive.
This study explored the role of subject commitment as a variable for increasing compliance rates in a university-sponsored tuberculosis (TB) detection drive. Return rates for reaction readings were compared between those subjects who had made an overt commitment to return (either a verbal or a verbal plus written agreement) and those subjects who were exposed to a standardized, no commitment procedure. Return rates under both commitment conditions significantly increased. Contrary to expectation, subjects with a known family history of TB were found to be a high-risk group for noncompliance. For this group, obtaining both verbal and written agreement from subjects appeared to be the most efficacious procedure to increase compliance.
