The self-injurious behavior of an institutionalized, highly social, highly verbal, midly retarded woman was successfully treated through the use of boxing glove restraints over a 30-week period after unsuccessful, less-intrusive means were attempted. Application of the restrain was conditioned to be an (S-delta), contrasted with an expanding Differential Reinforcement of Incompatible behavior (DRI) during periods of restraint removal. Absence of self-injury was maintained at 18 month follow-up by which time she had been discharged to a community placement.

Ten patients with oral habits such as biting, chewing licking, or pushing of the cheeks, lips, teeth, or palate were randomly assigned to either habit reversal treatment or to negative practice treatment. Treatment was given in a single 2-hr session. The patients receiving negative practice treatment showed a mean reduction of about 65%, those receiving the habit reversal treatment showed a mean reduction of about 99% during the 22-months of follow-up.
In vivo desensitization procedures were used successfully to manage self-injurious face slapping in a 10 yr old retarded boy. Face slapping had increased and persisted at self-injurious intensity following a surgical dental evaluation and had initially been prevented by the use of a hockey helmet. Parent's efforts to remove the helmet resulted in increased agitation, severe self-injurious behavior, and repeated efforts by the child to replace the helmet to restrain himself, or prompt adult restraint. An in vivo desensitization procedure involving increasingly extended periods without the helmet was introduced by the parents into a hierarchy of situations at home. Progress was monitored across four situations using a multiple baseline design with 6, 9, 12 and 15 month follow-up on each baseline. During treatment, self-injurious behavior was eliminated and the child developed a self-control response of wearing the helmet when agitated and spontaneously removing it when relaxed. Continued improvement was noted at 6, 9 and 12 month follow-ups. At the 15 month follow-up, no self-injurious behavior was observed and the use of the helmet was discontinued.
This clinical case study extends the literature on behavioral treatment of self-injury to an intellectually normal infant with spina bifida and diminished sensitivity to pain. After treatment by attention-play periods plus an aversive tasting substance applied to the injured finger, severe biting of the index finger was eliminated and the finger healed. Follow-up inquiries 2 months, 2 and 3 yr later revealed no biting and no substantial tissue damage.
A profoundly retarded male with severe congenital impairment of vision and hearing was treated for self-inflicted eye gouging. Prior to intervention, continuous mechanical restraint was required to prevent the response, precluding participation in educational and play activities. The response topography, the nature of the client's deficits, and a preliminary behavioral and medical assessment suggested that the response functioned as a source of sensory self-stimulation. Presentation of toys plus differential reinforcement of other behavior (DRO) as alternate sources of stimulation during baseline had no impact on eye gouging. The introduction of a contingent response interruption procedure reduced eye gouging and decreased the amount of time spent in restraints. Treatment effects were replicated in a group setting, and in the natural environment. Parents and school personnel were trained to use the treatment, and eye gouging remained infrequent at a 9-month follow-up.
A treatment technique is presented which has been developed to eliminate chronic self-induced wrist cutting behavior. The technique substitutes painful but non-injurious exercises for self-cutting behavior when the urge to self-cut emerges. The rationale for initiating this approach is described.
This study introduces the Bubble Helmet, a protective device, as an effective means of treating severe cases of self-biting behavior with disturbed developmentally disabled persons. The apparatus is a clear plastic sphere which fastens over the client's head, shielding the mouth from contact with hands and forearms. Use of the bubble in a response-contingent manner effectively eliminated the intense self-biting behavior of a 9-year-old autistic child in a community-based group home. This made it possible for her to be placed in a less restrictive community facility.
Self-injurious hand biting was reduced in an autistic girl by using fine water mist combined with a loud statement of "No!" following the behavior, and verbal praise for appropriate behavior. The subject was 6 years old when the interventions were implemented, and she had been in arm and head restraints since infancy. A fading procedure that moved from a large to smaller bottles allowed generalization across settings and people. Treatment was effective at a 6-month follow-up in both structured and unstructured settings.
This case study illustrates an empirical approach to the diagnosis, treatment, and controlled follow-up of self-injurious clients. Following an assessment period, during which environmental factors associated with a severely retarded adolescent's self-injury were identified, the contingent application of protective equipment was combined with a differential reinforcement procedure (DRO) and implemented in a multiple baseline design across two hospital settings. Results showed a marked decrease in the rate of self-injury. Upon discharge from the hospital, the program was successfully replicated at the adolescent's residential center, again using a multiple baseline design across settings.
The treatment of a 16-year-old severely mentally retarded and blind female client exhibiting severe biting of self and others consisted of the contingent application of an aversive gustatory stimulus (Tabasco Sauce), brief timeout, DRO, and contingent restraint against biting while in time-out. This is the first use of Tabasco as the aversive stimulus against biting. Deceleration of biting was rapid and maintained for 20 months after initiation of treatment.
The frequency and intensity of a 14-year-old profoundly retarded male's self-injurious behavior was significantly reduced by the reinforcement of calm sitting behavior. Social validation ratings confirmed the effectiveness of treatment, and showed that gains generalized across treatment and non-treatment settings and across people associated or not with treatment. Treatment gains were maintained at 6- and 12-month follow-ups.
Pharmacological and contingency management interventions are frequently used to treat self-injurious behavior but few comparative analyses of these therapeutic approaches have been conducted. The present studies evaluated the singular and combined effects of psychotropic medication and behavior modification programs on multiple forms of self-injury in two developmentally disabled children. In both cases, high rates of self-injurious responding persisted during medication administration but were reduced rapidly following the implementation of behavioral programming. Near-zero levels of self-injury were maintained while the children were weaned gradually from medication and during extended follow-up assessments. Issues relevant to clinical behavioral pharmacology and self-injurious behavior are discussed.
We examined the effectiveness of a bubble helmet and differential reinforcement procedures in the treatment of the self-injurious behavior (SIB) of three adult residents of a state hospital for the developmentally disabled. A multiple-baseline design across settings and an ABC design were used to assess the effectiveness of these procedures. Results indicated that the introduction of the bubble helmet in conjunction with differential reinforcement procedures produced notable reductions in SIB for all three participants. These reductions were significantly greater than those produced by using the differential reinforcement procedures alone. Social validity, generalization and follow-up data further documented the efficacy and acceptability of the bubble helmet plus differential reinforcement procedures. The advantages of the bubble helmet over other forms of restraint and the theoretical implications of these findings are also discussed.
