The research examines the effects of transactional analysis (TA) 101 training upon self perceptions of ego-state dynamics, using the model of ego states incorporated into the Adjective Check List (Gough & Heilbrun, 1980). Subjects completed the question-naires at the beginning and end of the training and one month later. The only statistically significant change was that Critical Parent decreased after the training and was still lowered one month later, although not as much. It was also found that gender was significant, but age was not.
