Effectiveness of the Cluster Randomized Comet-program Behavioral Preschool Teacher Training in Reducing Externalizing Behavior

Study:

A cluster randomized controlled pre-post effectiveness trial of behavioral preschool teacher training (BPTT) delivered in a practitioner assisted group format for children with externalizing behavior problems. Preschools were randomized to either intervention in 25 preschools or to 22 waiting list control preschools, where preschool classes with the target child or children were program receivers. Informed preschools could apply for participation in the study, then, target children were screened for eligibility. Participants were 100 target children 3-5 years old together with 72 enrolled preschool teachers and 83 parents as informants of behavioral outcomes after a five months period of implementation (at six months).

Intervention:

The intervention was part of the Swedish evidence-based parent and teacher training programs (COmmunication METhod - Comet) for children and youths aged 3-12 and 12-18 years with moderate or elevated externalizing behavior, usually delivered in practitioner assisted group formats but previously evaluated as delivered via internet, single workshops followed by self-administered training, and universal prevention as well. Program implementations and evaluations are executed as collaboration projects between university researchers and the social services administration at place. Intervention content is influenced by operant conditioning, social learning theories, applied behavior analysis, and coercion theory. The focus is to establish a positive and effective interaction and communication style primarily through different reinforcement techniques (e.g., selective attention, more to positive behaviors and less to negative behaviors) and modeling. Parents or teachers meet in psychoeducational group sessions (often 9 to 11 sessions à 2.5 to 3 hours) led by one or two practitioner supervisors. They each follow a comprehensive manual and a highly structured curriculum. Training occurs at sessions (role-plays) and between sessions together with the children, followed-up with feedback in the next session.

Here an adapted version was tried in the preschool setting for the first time. The program corresponded in much to the parent training supplemented with techniques from the school teacher training and a group level administrated glove-puppet play technique to foster children's prosocial skills. (Results from the universal part of the program are not reported.) The nine sessions curriculum consisted of 2.5-hour biweekly meetings and two optional visits from supervisors with coaching on the spot. Practitioner supervisors (n = 27) were educated by a cognitive-behavior oriented psychologist during five days term one and two days term two.
