The happiness indices in a Fun Time activity were systematically increased for three of four people with profound multiple disabilities by providing their preferred stimuli. The fourth showed decreased unhappiness. However, three people with profound disabilities and minimal movement failed to show any indices of happiness or unhappiness.…

Four experiments with six students with multiple profound disabilities examined the function of behavioral stereotypies and sensory modalities maintaining them. Findings are discussed in terms of the sensory and social reinforcers that maintain stereotypy, assessment procedures used to identify reinforcers, and the interpretation of assessment…

The clinical histories and treatment of 9 individuals with Down syndrome and major depression are presented, as are clinical characteristics of an additional 13 individuals. Vegetative symptoms of disinterest, withdrawal, mutism, psychomotor retardation, decreased appetite, and insomnia were prominent. Preoccupations with suicide, death,…

Mentally retarded emotionally disturbed children (N=31) were compared on the Child Depression Inventory and the Child Behavior Profile with 31 children in a normal school setting. Correlational data showed a strong relationship between the cut-off scores for both measures suggesting that similarities exist between depression in mentally retarded…

A study attempted to assess preferences between a task arrangement involving mobility and a task arrangement involving sedentariness with three women with severe disabilities and visual impairments or blindness. Results found that participants' preferences about task arrangements could be successfully assessed. (Author/CR)

Two experiments with 15 individuals having profound mental retardation found difficulties in identifying reinforcers that were actually effective in treatment of chronic training needs. Research needs in evaluating training alternatives for people with profound multiple disabilities who move very little or who respond with very long latencies are…

Reevaluation of two studies on relationships between nonhandicapped and severely mentally retarded children (ages 8-12) suggested that nonhandicapped children work harder, receive and emit fewer social reinforcers, have less opportunity to play and have fun, and achieve lower levels of social play when the playmate is physically handicapped as…

In a population of 425 individuals with Down's syndrome, 5 persons (1.2%) were identified as having Tourette's disorder. The lack of interrelationship between Down's syndrome and Tourette's disorder argues against an atypical Tourette's disorder. Diagnoses of tardive Tourette's disorder were based on absence of family history of Tourette's, late…

This study evaluated the reliability of the Child Behavior Checklist with 42 children and youth with mild mental retardation. Use of kappa coefficients and intra-class correlations at item and syndrome levels indicated that the Child Behavior Checklist may not always represent a reliable checklist for the assessment of psychopathology in this…

This study examined aggression and psychopathology in 70 persons with severe or profound mental retardation. Most aggressive episodes were directed toward other clients; aggression was positively correlated with self-injury, stereotypic behavior, and being ambulatory. Aggression was most consistently predicted by dependent personality and…

A study evaluated an off-site/on-site program for reducing job coach assistance provided for three adults with severe multiple disabilities in a part-time community job. On-the-job assistance was reduced, while the individuals received more traditional day services when not at work. No adverse effects on productivity were observed. (Contains…

The Psychopathology Instrument for Mentally Retarded Adults was used to diagnose 163 mentally retarded institutionalized adults according to the Diagnostic and Statistical Manual-III axis 1 categories. Nine factors were extracted which contained 49.3 percent of the data variance and categorized correctly 69.3 percent of the cases. Factors included…

This study assessed a microswitch-based program in which three request and one choice microswitches were used for two participants with multiple disabilities. Each request switch was linked to different stimulation opportunities. Both participants learned to use the microswitches very rapidly. Responding levels were high during intervention and…

The study investigated the effectiveness of an instructional program designed to promote independent walking in a mentally and physically handicapped (cerebral palsied) preschooler involving a collaborative effort between a behavior therapist and a physical therapist in an interdisciplinary setting, a public school. (Author/DB)

This study assessed the effects of automatically delivered stimulation on the activity level and mood of three students with multiple disabilities during their use of a stepper and a stationary bicycle. Stimuli from a pool of favorite stimulus events were delivered electronically while students were actively exercising. Findings indicated the…
