Single-case experimental designs (SCEDs) provide a time- and cost-effective alternative to randomized clinical trials and offer significant advantages in terms of internal and external validity. A brief history and primer on SCEDs is provided, specifically for use in suicide intervention research. Various SCED methodologies, such as AB, ABAB,…

Although a number of investigators have adopted the O'Carroll et al. (1996) nomenclature and applied it in their studies, and others have acknowledged its role in highlighting the need for clarification of terms, the nomenclature has not been widely used in the research and clinical communities. The rationale behind the rebuilding of the O'Carroll…

This paper reviews hypotheses suggesting psychological, behavioral, physiological, or neurochemical factors as causes of self-injury in individuals with severe/profound mental retardation. A compulsive behavior hypothesis is introduced, suggesting that self-injury occurs with cerebral dysfunction is compulsive, may occur in the context of a…

Double blind study compared effects of two drug treatments, naloxone hydrochloride and naltrexone hydrochloride, on self-injurious behavior of a 12-year-old mentally retarded and autistic girl. Self-injury increased with naloxone treatment but decreased to near zero with naltrexone, a change which persisted at follow-up 22 months after treatment.…

Analysis of the reinforcement and extinction components of differential reinforcement of other behavior (DRO) of three women with developmental disabilities and self-injurious behavior (SIB) found that DRO was only effective in combination with the relevant extinction component (withholding of attention for SIB). (Author/DB)

Assessment of self-injurious behavior (SIB) in three individuals with developmental disabilities revealed that the behavior was an escape response maintained by negative reinforcement. Treatment consisted of extinction plus instructional fading and resulted in immediate and large reductions in SIB behaviors. Maintenance occurred as instruction…

A survey of 39 psychologists at a state school for mentally retarded persons assessed the prevalence of self-restraint, self-injurious behavior (SIB) and other maladaptive behaviors. Results indicated that almost all clients engaging in self-restraint also engaged in self-injurious behavior. (Author/DB)

Questionnaires documenting self-injurious behavior (SIB) among 113 elementary students were returned by 21 London schools. Cluster analysis found patterns of behavior associated with each other, indicating that SIB may not be a homogeneous condition but may comprise a number of distinct syndromes depending on sex, age, mobility, communication…

The literature review looks at self-injurious behaviors in handicapped students in terms of characteristics, prevalence, etiology (biological, psychological, and as learned behavior), and management including extinction, positive punishment, negative punishment, and reinforcement of other behaviors. Problems in areas of management, administration,…

This study presents three cases of adults with profound developmental disabilities in which assessment data showed that self-injurious behavior occurred in at least two test conditions and describes a method used to analyze the effects of treatments based on hypotheses of multiple control. (Author/DB)

This study effectively eliminated face-slapping behavior in a 10-year-old boy with severe developmental disability and autistic characteristics. The subject wore wrist weights for up to 30 minutes each day. Face slapping did not occur during a follow-up check conducted five months after study completion. (Author/DB)

This paper is set against the backdrop of an increasing number of strategies and policies developed by the Department for Education and Skills in the U.K. regarding the promotion of positive mental health in schools and the recognition of the value of improving mental health in relation to children's learning, achievement, attendance and…

This study compared differential reinforcement of other behavior (DRO) and noncontingent reinforcement (NCR) in the reduction of self-injurious behavior in three adult females with severe or profound mental retardation. Both procedures were highly effective in reducing self-injury, with NCR less limited than DRO. (Author/DB)

A reevaluation of data from Berkman and Meyer (1988), a study supporting the effectiveness of positive-oriented programing approaches with persons with mental retardation, suggests that medication, especially the introduction of Thorazine (with subsequent increases of dosage), may have been related to reductions in the client's self-injurious…

The response satiation model of instrumental performance was used in two experiments to establish contingencies which reduced the self-injurious behavior of two adults with profound mental retardation and multiple handicaps. Transfer and generalization of training effects were also observed. (Author/DB)
