This pilot study focused on the effects of assertion training on physically disabled university students' acceptance of disability. A pretest-posttest control group design was utilized. Subjects were randomly assigned to either a treatment group or a no-treatment control group. The hypotheses analyzed were that individuals given assertion training would show increases in acceptance of disability scores, self-concept/esteem scores, and social interaction skills scores when compared with individuals who did not experience assertion training. Significant results beyond the .05 level of confidence were obtained for all hypotheses. It was concluded that the groups differed in acceptance of disability, self-concept, and social interaction. The study indicated that assertion training may be effective for increasing acceptance of disability in physically disabled university students.Acceptance of disability is a crucial variable in the rehabilitation process. (Dembo, Leviton, & Wright, 1956;Wright, 1960). Linkowski and Dunn (1974) indicated a relationship between self-concept and acceptance of disability. Others have found acceptance of disability to be important for rehabilitation and the adjustment of the physically disabled to their environment (Cull & Hardy, 1972;Wright, 1960). Safilios-Rothschild (1971) stated that interpersonal relations were greatly influenced by disability. Wright (I960) concluded that selfconcept was important in determining expectations that physically disabled individuals have concerning the attitudes of others toward themselves and, as such, should be emphasized when attempting to deal with acceptance of disability by a physically disabled person.An effective technique that has improved interpersonal interaction skills and increased perception of self-worth in various populations is assertion training (Cotler, 1975). Assertion training teaches a process that encourages independent action; that is, people learn to say clearly This study is based on a doctoral dissertation submitted by Brenda Morgan to the Rehabilitation Department of the University of Arizona.
