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,…

Matson, Johnny L.; And Others – Research in Developmental Disabilities, 1988
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…

Ivancic, Martin T.; Bailey, Jon S. – Research in Developmental Disabilities, 1996
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…

Cole, David A. – Research in Developmental Disabilities, 1988
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…

Myers, Beverly; Pueschel, Siegfried M. – Research in Developmental Disabilities, 1995
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…

Embregts, Petri J. C. M. – Research in Developmental Disabilities, 2000
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…

Linaker, Olav – Research in Developmental Disabilities, 1991
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…

Lancioni, Giulio E.; Singh, Nirbhay N.; O'Reilly, Mark F.; Oliva, Doretta – Research in Developmental Disabilities, 2003
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…

Lancioni, Giulio E.; O'Reilly, Mark F.; Singh, Nirbhay N.; Oliva, Doretta; Marziani, Monia; Groeneweg, Jop – Research in Developmental Disabilities, 2002
This study examined the social validation of using microswitches versus interaction/stimulation conditions with persons with multiple disabilities. Teacher-assistant trainees and rehabilitation staff (n=72) were shown videotapes comparing the two methods and then scored both approaches. The microswitch condition was viewed as generally more…

Linscheid, Thomas R.; And Others – Research in Developmental Disabilities, 1994
The rate of self-injurious head hitting in an eight-year old with severe/profound mental retardation was reduced using contingent electric shock delivered via the Self Injurious Behavior Inhibiting System. An improved affective state and increased interaction with the environment were documented. Treatment gains were maintained at one-year…

Swiezy, Naomi B.; And Others – Research in Developmental Disabilities, 1995
The validity of the schizophrenia subscale of the Psychopathology Instrument for Mentally Retarded Adults (PIMRA) was evaluated with 65 adults having mild to moderate mental retardation as well as either schizophrenia, depression, or no psychopathology. Univariate and multivariate analyses were conducted, as were interrater reliability analyses.…

Linaker, Olav M.; Helle, Jon – Research in Developmental Disabilities, 1994
This study found that the schizophrenia subscale of the Psychopathology Instrument for Mentally Retarded Adults was a valid quantitative measure of schizophrenia if one item was removed from the scale. Comparison with a nonretarded population indicated that mentally retarded patients had less delusions and more incoherence and flat affect. They…

Matson, Johnny L.; Bamburg, Jay W. – Research in Developmental Disabilities, 1998
The initial psychometric properties of the Assessment for Dual Diagnosis (ADD), a new scale designed to screen for psychopathology in individuals with mild and moderate mental retardation, was examined. The ADD was found to have high stability across raters, high stability over time, and good internal consistency. (Author/DB)

Fifty children and adolescents with affective disorders and mental retardation admitted to a psychiatric inpatient unit were compared with 50 inpatients without depression.
