Abstract Two studies reassessed the validity of Rotter's Incomplete Sentences Blank (ISB), Experiment I used a sociometric measure of adjustment, Subjects were members of two sororities and two fraternities (N = 116) at the University of Connecticut. Experiment 2 compared clinic (120 student clients at the campus Student Mental Health Service) and control (120 students from introductory psychology classes and campus sororities and fraternities) samples at the University of Connecticut, The results of Experiments 1 and 2 both were significant and substantiate the validity of the ISB as a measure of adjustment. Results from Experiment 2 also provide new cutting scores to differentiate adjustment from maladjustment as measured by the ISB, support the validity of the scoring procedure of adding a point to item scores for lengthy response, and suggest that ISB mean scores are continuing to decline and, therefore, new norms are needed.
