Effect of behavior modification on patient compliance in orthodontics.

The purpose of this study was to evaluate the effects of a reward system for improving patient compliance in orthodontic treatment. The sample consisted of 144 orthodontic patients (63 male, 81 female, average age 12.8 years), 6 to 12 months into their treatment. The sample was divided into above-average and below-average compliers, based on the orthodontic patient cooperation scale (OPCS). Each group was further divided into three subgroups: (a) a control group, which received only standard instructions; (b) an award group, which received compliance instructions and a written evaluation of compliance; and (c) a reward group, which received compliance instructions, a report card, and eligibility to receive rewards for adherent behavior. Two measurements of patient compliance were used: (1) the OPCS, which divided the sample into high and low compliers and was used to compare compliance before and after the 6-month experimental period; and (2) a clinical evaluation of compliance that was based on oral hygiene, appointment punctuality, appliance wear, and appliance maintenance. Evaluations were completed at each monthly appointment. Average compliance scores of above-average compliers showed no significant improvement with rewards. The average scores of patients with below-average compliance did not improve significantly. Only oral hygiene scores in the low compliance reward group were better than in the low compliance control group. Academic performance in school was found to be correlated (p < 0.001) with compliance. Above-average compliers remained above average in their compliance. The award/reward system may help motivate below-average compliers to comply with prescribed instructions.
