This article reports the results of a study examining self-efficacy and relapse in patients treated in a substance abuse facility for alcoholism. Relapse was measured as a two-stage process of "Lapse" and "Relapse." The results did not support the previous findings that self-efficacy ratings measured post treatment were valid predictors of treatment outcome status. In examining the results, it is proposed that a condition of "post treatment denial" is operating among patients.
