This study tested the applicability of Protection Motivation Theory (PMT) to compliance with a medical treatment regimen. PMT model emphasizes the cognitive processes that mediate health attitude and behavior changes. In the first phase of the investigation 100 subjects, parents of children with muscular dystrophy completed the PMT questionnaire and self-report measures. In phase 2, two behavioral self-report items and four items measuring maladaptive response rewards were used in addition to those used in phase 1. Results show that PMT variables may have applicability beyond self-protective behavior. Threat appraisal appeared to operate differently for people experiencing an illness than for those at risk for illness. PMT provided a useful explanation for actions taken on behalf of another person's health. When treatment was seen as effective, it was more likely to be enacted.
