As measured by the Social Responsiveness Scale, second edition (SRS-2), 65 participants (83.33%) met clinical cut-off…

This study compared the occurrence and characteristics of self-stimulatory behaviors of 5 children with developmental delays and 10 nondisabled children (matched for either mental or chronological age). Few differences were found between groups in percentage of time spent in self-stimulatory behavior, the variety of such behaviors, the speed at…

Relative prevalence of stereotyped behaviors was studied with 246 children and adults with developmental disabilities. Two staff members completed a 54-item checklist assessing stereotyped behaviors, abnormal focused affections, compulsions, rigidity, savant skills, and defensiveness. Factor analyses produced weak evidence for a general stereotypy…

The follow-up study examined 16 schizo-affective children after a mean of 16 years. In comparison to purely schizophrenic controls, subjects showed an increased incidence of affective psychoses, suicide in the ancestry, and more pre-morbidly well-adjusted personalities. The schizo-affective psychoses had mainly an acute-recurrent character.…

A study of 571 Australian children (ages 4-18) with mental retardation investigated potential behavioral risk factors for injury. Results found the prevalence of potential injury risk behaviors to be higher than for typical children and that the behavioral injury risk patterns reflected those seen in younger aged typical children.

Sleep patterns of 103 institutionalized individuals with profound mental retardation were explored. Almost 40% were found to have short-sleep patterns. Short-sleep was predicted by blindness; nonshort-sleep was predicted by diagnosis of cerebral palsy and sodium valproate usage. Techniques for minimizing possible negative consequences of…

Tests of executive functions and control tasks not assessing executive function were administered to 19 individuals (ages 6-28) mild hyperphenylalaninemia (MHP) and 19 controls. Tests of academic skills and behavior-rating questionnaires were also administered to the group with MHP. No group differences were found for any measure. (Contains…

In this Netherlands study, 41 deaf boys (ages 6 to 11) were compared to hearing children using the Child Behavior Checklist. The deaf boys appeared to have more internalizing and externalizing behavioral problems but were no more often disturbed than their hearing counterparts. Younger deaf boys showed more behavioral problems than older deaf…

Assessment of 84 children diagnosed with controlled or uncontrolled complex partial or absence seizures but no documented learning or emotional disorders found no influence of seizure type on achievement test scores or behavioral ratings. A main effect was found for degree of control, with poorly controlled seizures correlating with lower reading…

This study documented suicidal behavior among 90 children and adolescents with mental retardation and psychiatric disorders in a psychiatric hospital. Suicidality was found in 21% of admissions and was distributed across gender, level of mental retardation, and psychiatric diagnosis. Results indicate that suicidality is an underrecognized but…

This study presents data on the physical, developmental, and behavioral characteristics of a group of 203 nonambulatory persons with profound mental retardation. It found a high prevalence of physical and medical problems, as well as high rates of self-injurious, stereotypic, and aggressive behavior and high variability in cognitive and adaptive…

This videotape recording and accompanying program manual are intended to provide a review of current knowledge about defiance in children, a behavior pattern that research suggests may be increasing in prevalence and that is a known precursor to serious disorders such as oppositional defiant disorder (ODD) and conduct disorder. The manual provides…

This article provides estimates of emotional and behavioral problems in children and their service utilization patterns. A model for the study of children's help-seeking pathways is offered and used to review the empirical support for variables associated with help-seeking, primarily help-seeking of formal mental health services.
