An assertiveness inventory for adults.

Developed the Adult Self-Expression Scale, a 48-item, self-report measure of assertiveness designed for use with adults in general. The scale was administered to 464 students at a large, "open-door" community college; Ss ranged in age from 18-60 yrs, with a mean age of 25.3 yrs. Results show the scale has high test-retest reliability and moderate-to-high construct validity, as established by correlations with Adjective Check List scales and by a discriminant analysis procedure. Factor analysis generally supported the model used in the construction of the scale. Concurrent validity was also established. (22 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
