The purpose of this study was to investigate the short-term effect of a parent-teen structured family facilitation program (PAT). The study compared pre and post workshop scores on a number of dependent variables in a workshop, a replication of the workshop, and a comparison group.Analysis of the data revealed no significant differences from pretest to post test in either of the groups. However when the groups were combined there were some statistically significant differences from pretest to post test. The fathers increased in their ability to transfer control while the mothers decreased in kindness. A few post hoc analyses were carried out to explore the possibility that several variables might influence the effects of the workshop. The data suggest that the level of proficiency of participants influenced the effects of the workshop. The less proficient the participants were the more they changed in a desirable direction. The comparison of families that volunteered for the workshop with the families that did not suggests that families that volunteer are significantly lower on most measures. It was suggested that one reason for the minimal effects is that the PAT program may have dealt with too many skills and not have put enough emphasis on any one of the skills to produce change.
