The primary aims of the present dissertation were to: (1) Bridge the existing gap between orthodontic care and motivational psychology. (2) Provide a reasonably coherent picture of the concept as well as the psychological prediction of the misunderstood phenomenon of orthodontic cooperation. Three psycho-orthodontic models of motivation were developed. These models were based--in essence--on the following three motivational theories: achievement, affiliation, and attribution. A sample of seventy orthodontic patients was studied. A double-blind quasi-experimental design was performed. Psychological instruments were used in order to measure achievement, affiliation, and attribution motivation. The following dependent variables were recorded: headgear wear, elastic wear, appliance maintenance, non-broken appointments, punctuality in appointments, oral hygiene, and plaque index. The raw data were analyzed by three different techniques. For the first (Technique One), the one-tailed Spearman rho correlation coefficient and the one-tailed Mann-Whitney U test were employed. The second (Technique Two) was composed of a multivariate stepwise regression analysis and six stepwise discriminant analyses. The third (Technique Three) consisted of a multivariate factor analysis and two multivariate stepwise regression analyses. The results obtained from the present study indicate that orthodontic cooperation is predictable through psychological testing. Specifically: high need achievers cooperate better orthodontically than low need achievers; high need affiliators cooperate better orthodontically than low need affiliators; and internals cooperate better orthodontically than externals. Further, it was found that orthodontic cooperation does not involve a simple single general dimension of cooperation. Rather, orthodontic cooperation is composed of a more complex structure of two orthogonal constructs: Specific Orthodontic Construct of Cooperation (SOCC) and Perio-Orthodontic Construct of Cooperation (POCC). Because SOCC and POCC are orthogonal, a patient who is a good toothbrusher does not have to be a good headgear wearer, and vice versa. The relative contribution of motivational psychology on each of the variables constituting orthodontic cooperation was presented. The implications for clinical applications were discussed.
