Treatment with two setting condition manipulations and use of a visual occlusion helmet was found to decelerate intense screaming by a 16-year-old girl with developmental disabilities. Cranial pressure was found to be the critical element in self-control, and replacing the helmet with a headband was found to be effective in maintaining behavior…

A study compared the effectiveness of two extinction interventions, extinction by omission and noncontingent delivery of reinforcement, to treat aggressive behavior with a 10-year-old boy. Analysis revealed that aggression was maintained by positive reinforcement in the form of attention. Noncontingent reinforcement of attention produced a more…

Sleep patterns of 30 individuals with self-injurious behavior and mental retardation were compared to 30 matched controls residing in the same residential facility who did not self-injure. Individuals with self-injury slept significantly less than individuals without self-injury. Neurochemical dysregulation in sleep disturbances among individuals…

To investigate stress among parents of mentally retarded children (aged 6-17) who demonstrate behavior disorders, 17 children who demonstrated disruptive behavior and 22 who did not, and their families, were assessed. Levels of children's pathology and aspects of family climate predicted the parental stress, pinpointing different variables for…

We compared partial-interval recording (PIR) and momentary time sampling (MTS) estimates against continuous measures of the actual durations of stereotypic behavior in young children with autism or pervasive developmental disorder-not otherwise specified. Twenty-two videotaped samples of stereotypy were scored using a low-tech duration recording…

A study of 233 individuals with severe mental retardation examined the validity of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) through correlation with the Aberrant Behavior Checklist (ABC). DASH-II as a whole was found to have a high degree of convergent validity with the ABC total score. (CR)

This study examined the effectiveness of self-operated auditory prompts when used to decrease the off-task and aberrant behaviors of two 19-year-old students with moderate mental retardation. Previous findings were replicated to demonstrate that stimulus control can be achieved through self-operated auditory prompts in school and community…

The Reiss Screen for Maladaptive Behavior was factor analyzed in 2 institutional samples and 1 community sample of persons with mental retardation (total n=353). Factor analysis revealed no strong justification for the instrument's seven scales. An alternative three-factor solution, comprising intrapersonal maladaptive behavior, psychotic…

A case study of a 25-year-old man with moderate mental retardation who engaged in self-injurious behavior included a functional analysis to determine the effects of the presence and absence of respite care. Results demonstrated a relationship between the presence of self-injury and the occurrence of respite care the previous evening. Altering the…

Evaluation of a training procedure to improve staff skills in the preventative and reactive management of severely challenging behaviors in a small residential treatment unit found reduced (though not statistically significant) behavioral incidents, use of major reactive strategies (restraint and emergency medication), and staff and resident…

This study used a data-based assessment to identify reinforcers and punishers for successful treatment of two children with severe destructive behaviors. Results suggested that empirically derived consequences may be useful in decreasing destructive behavior when a functional assessment is inconclusive or suggests that internal stimuli are…

The behavior disorders of 54 Japanese individuals with mental retardation receiving antipsychotic medication were compared to 52 subjects receiving anticonvulsants and 202 subjects without medication. Results found the problem behaviors of subjects receiving antipsychotic drugs were more severe and severity of disability was associated with higher…

This study applied functional behavioral analysis to the destructive behaviors of two young boys with multiple disabilities including behavior disorders. Results suggested that the subjects' destructive behaviors were sensitive to both escape and attention as reinforcers. Results support the importance of establishing operations in determining the…

Three analyses were conducted to assess the effects of different consequent stimuli on the stereotypical and self-injurious behavior of two children with severe developmental disabilities and dual sensory impairments. Contingent presentation of the specially selected stimuli plus response interruption resulted in more suppression than contingent…

This replication study found that only 16 of 55 raters agreed on the category of reinforcement maintaining a disabled individual's self-injurious behavior after using the Motivation Assessment Scale. Additionally, only 15 percent of the correlation coefficients obtained were above 80 percent, and none of the reliability scores was above 80…
