This study reviewed the literature on the clinical features of Asperger Syndrome, a form of autism, looking for evidence that a tendency toward violence is common in individuals with the syndrome. Although many studies were excluded on the basis of inadequate data, findings of remaining studies did not support the speculation that violence is…

Evaluates the efficacy of a multisystemic approach to treatment of juvenile offenders and their families. One group of delinquent adolescents received family-ecological treatment, another group of delinquent adolescents received an alternative treatment, and normal adolescents served as developmental controls. Findings support a multisystemic…

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…

Three models of behavioral effects of genetic disorders characterized by mental retardation were compared: (1) no-specific effect model (all genetic disorders have identical behavioral outcomes); (2) totally specific model (each genetic disorder has unique outcomes); and (3) partially specific model (two or more genetic disorders share outcomes…

This study compared the effects of unequal and equal reinforcer duration during a functional analysis of aberrant behavior in an 11-year old with moderate mental retardation. Results showed that reinforcer duration affects the rate of aberrant behavior and may potentially alter functional analysis interpretation. (DB)

Functional assessment is redefining the standards for clinical interventions with problem behavior and reemphasizing the importance of basic behavioral mechanisms. It has shown the importance of complex patterns of behavioral control, functional assessment as an ongoing process, and the importance of attention to antecedent variables. Future…

Two case examples (a toddler with severe developmental delays and a 7-year old with severe mental retardation) illustrating effects of meal schedule and food quantity on displays of problematic behavior are offered. Brief functional analyses of aberrant behavior provided useful information for interpreting distinct patterns of behavior. (DB)

This study compared maladaptive behavior in 23 people with Prader-Willi syndrome due to paternal deletion and in 23 age- and gender-matched subjects with maternal uniparental disomy. Controlling for IQs, the deletion cases showed significantly higher maladaptive ratings, more symptom-related distress, and more behavior problems. Findings suggest a…

A survey of the families of 62 persons with Prader-Willi syndrome examined the prevalence, topographies, and specific body locations of self-injurious behaviors. Self-injury was reported for 81% of the participants. Skin-picking was the most prevalent form with the front of the legs and head being disproportionately targeted. Incidence also varied…

Clinicians need to know the likelihood of a condition given a positive or negative diagnostic test. In this study a Bayesian analysis of the Clinical Behavior Checklist for Persons with Intellectual Disabilities (CBCPID) to predict depression in people with intellectual disability was conducted. The CBCPID was administered to 92 adults with…

The frequency of sexual behaviors among 251 preschoolers attending Swedish day-care centers was evaluated. Some behaviors were frequently occurring (like clinging body contact) whereas others were very uncommon (touching an adult's genitals). Correlations between age and single behaviors were seen as manifestations of the socialization process.…

Interviews with 60 female victims (ages 7-12) of sexual abuse found that most viewed relationships with their mothers as warm and accepting. Girls who perceived lower maternal rejection had higher competency ratings and fewer behavior problems. Abuse involving force was correlated with lower victim competency. More violent abuse was correlated…

Data concerning maladaptive behavior obtained on a sample of persons (n=8255) with mild to profound mental retardation and aged from birth to 98 years were factor analyzed resulting in identification of 2 principal factors for children, 3 for adolescents and young adults, and three and 4 for middle and older adults, with level of retardation also…

This study evaluated a method for assessing the behavioral function of severe self-injury in four adults with severe/profound mental retardation. Initial assessment included analyzing within-session trends and fluctuations in rates of self-injury by plotting the frequency within each minute of the session. (DB)

Comparison of scores on the Child Behavior Checklist of 1,120 Flemish and 1,122 Dutch children, aged 6 to 12 years, found no differences between groups on total problem scores, higher scores for Dutch children on the Activities scale, and higher scores for Flemish children on the School scale. (DB)
