Reports results of a 1-yr follow-up of group assertive training with 20 of the 32 nonassertive college students in the original study. One yr after training, experimental and control Ss were significantly different on 2 self-report measures (the College Self-Expression Scale and the Subjective Unit of Disturbance Scale) and 2 of 4 behavioral measures (assertive content and scene length) of assertiveness. No differences were found on eye contact or response latency. Results indicate the long-term effects of assertive training. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
