Cooperation of adolescents in orthodontic treatment

Cooperation of 39 adolescents with orthodontic treatment was examined 8-10 months into treatment and again at completion. Early in treatment, parental attitudes served as the best predictors of cooperation. By the end of active treatment, however, the adolescent patients' own cognitions were the most salient predictors of cooperation. Prior to beginning orthodontic treatment, subjects and their parents completed a battery of psychosocial and orthodontic-specific measures. Results of stepwise multiple regression analyses showed that only the Parent Positive Attitude Toward Braces measure significantly predicted orthodontic cooperation early in treatment, while External-Powerful Others (Professionals) attributions of control, External-Chance attributions of control, and the initial assessment of cooperation significantly predicted cooperation over longer periods of time.
