The reliability of a new scale to assess Autistic Disorder, Pervasive Developmental Disorder, Not Otherwise Specified (PDD-NOS), and Asperger's Disorder in children was examined. Parents or other caregivers rated symptoms of 207 children between 2 and 16 years of age. The scale, which had 40 items in the final version, correlated highly with…

Parents of 601 children and adolescents with mental retardation rated their children on the Aberrant Behavior Checklist-Community (ABC). Factor analysis revealed a factor structure similar to the original ABC but without the inappropriate speech factor. Analysis of subject variables revealed main effects for gender, age, and classroom assignment…

The factor structure of the Autism Behavior Checklist (ABC) was examined with 383 individuals (aged 5-22 years) with autism spectrum disorders. A five-factor model accounted for 80% of the total variance. However, no support was found for classifying the checklist's 57 items into the previously proposed five subscales. (Contains references.)…

Analyzes sex-related differences between mental rotation rate and spatial ability among adults, 14-year-olds, and 9.5-year-olds to determine the extent to which rotation rate is a correlate of various abilities. (HOD)

Analysis of teacher and parent ratings of 369 children with developmental disabilities on the Nisonger Child Behavior Rating Form provided normative data (means, T scores, and percentiles). Age influenced three of eight subscales on the parent ratings and one subscale on the teacher ratings. Gender did not influence subscale scores. (Author/DB)

This study investigated the stability of the four factors in the Quality of Life Questionnaire, an instrument often used in quality of life research for people with intellectual disabilities. Only three of the four factors were found to be stable, raising potential concern over the use of the measure in assessing service providers' effectiveness.…

This paper describes two measurement integrity analyses conducted using data on the Battelle Developmental Inventory, obtained from a sample of 78 children with severe disabilities. Procedures used to conduct internal reliability and construct validity analyses are discussed. Researchers are urged to evaluate a test's construct validity when their…

This study examined the validity and internal and interrater reliability of the Wing Subgroups Questionnaire, an assessment that classifies children with autism into subtypes. Subjects were 42 students (ages 5 to 22) enrolled in multihandicapped special education classrooms. Findings support the reliability and validity of the questionnaire for…

This study compared psychometric results on the Fear Survey Schedule for Children-II for 187 children and adolescents with mental retardation and 372 intellectually average students. The schedule demonstrated sound psychometric properties for both samples. Mentally retarded subjects scored significantly higher than the comparison sample, and their…

This paper offers a rationale for and a description of the creation of the Developmentally Delayed Children's Behaviour Checklist, which is completed by caregivers or teachers and uses a taxonometric model to describe the child's (ages 4-20) disturbed emotions and behaviors. Results of clinical validation studies are cited. (Author/JDD)

This manual describes the Wisconsin Sensorimotor Pointing Assessment (WSPA) for individuals with severe communication deficits complicated by other cognitive or motor disabilities, and provides guidelines for its administration. The WSPA was designed to quantify four categories of sensory and motor abilities necessary for initiating and accurately…

A review of research on the cognitive, linguistic, and scholastic development of mainland Hispanic-American children paints a dismal overall picture. Hispanics are the fastest growing ethnic group in the United States, 11% of the population in 1986; about 75% have Mexican ancestry. Less than half of Latin adults speak English well enough for the…
