A group outcome study evaluated the effectiveness of four treatment procedures in reducing self-injurious behavior among 22 severely handicapped students (mean age 10.5 years). Contingent restraint was most effective in reducing behavior below baseline levels. (Author/CL)

Evaluated was the effectiveness of four treatment procedures in reducing self-injurious behaviors (handbiting and headstriking) of 22 nonverbal severely mentally retarded children, approximately 10 years old. Among results were that contingent restraint was more effective in reducing behavior below baseline levels than positive reinforcement,…

The effectiveness of four operant procedures (differential reinforcement of incompatible behavior, omission training, overcorrection, and reinforcement withdrawal) in changing self injurious behavior (SIB) of 16 severely handicapped students was examined. Analysis of correlations between reduction in SIB and subject characteristics, adaptive…

Four treatment procedures were evaluated for effectiveness in reducing self injurious behavior (SIB) of 22 severely handicapped students. Treatment procedures included contingent restraint, reinforcement withdrawal, differential reinforcement of incompatible behavior, and ommission training (rewarding the S for not emitting the SIB response).…

Findings showed an interaction between mands (instructional directions) and response type. Only when a mand was given during performance of the sorting task did the frequency of SIB increase. The contingent application of verbal praise had a minor, though systematic, effect in reducing the frequency of SIB. (PHR)
