Concurrent validity testing of the Slosson Intelligence Test-Revised with the Stanford-Binet Intelligence Scale (Fourth Edition), involving 191 individuals (ages 5-69 and IQs of 36 to 110), found a high correlation between the two scales. However, the Slosson unsatisfactorily matched the Stanford-Binet's assignment of individuals to IQ categories.…

The validity of the Five Dimensional Life Satisfaction Index was evaluated with 48 adults with moderate mental retardation. Results showed reliability of alternate forms and internal consistency, convergent and discriminant validity, and construct validity. (Author/DB)

The methodology of many studies that have identified specific genetic loci for disorders associated with mental retardation is criticized as failing to demonstrate an association between the behavior phenotype and the genetic marker. A more appropriate methodology using a multitrait-multimethod approach is suggested. (Author/JDD)

This study evaluated facilitated communication with 12 people living in an institutional autism program. On trials when facilitators and participants saw different pictures, the only "correct" labels were for pictures shown to the facilitators and not shown to the participants. Results suggest that the facilitators were unknowingly…

Psychometric analyses of data from 230 individuals yielded a 29-item 4-scale revision of the original 50-item 5-scale Mental Retardation Attitude Inventory. Results showed adequate item characteristics; adequate reliability and homogeneity; adequate reliability, homogeneity, specificity, and independence of the four scales; and initial validity…

The Test of Knowledge about Mental Retardation was developed to measure attitudes, not knowledge. It consists of 20 error-choice items requiring respondents to select one of four incorrect alternatives. An additional 20 questions address general knowledge of mental retardation. Psychometric analysis indicates satisfactory item characteristics,…

This study assessed the degree of agreement between teacher report and an adapted Adaptive Behavior Scale in the identification of mental retardation and associated learning difficulties in 257 young Bahraini school children. Findings indicated that the instrument is sensitive in identification of children with mental retardation and exhibits high…

This study evaluated the Consent Screening Interview, which assesses the ability of adults with developmental disabilities to give direct consent for community residential placement. Interviews conducted with 17 adults with mental retardation and a control group of 8 individuals indicated that the instrument differentiated between those subjects…

This study derived data from the Family Environment Scale, from home visits to 29 individuals with moderate mental retardation, and from other sources to determine that the Parenting Style Survey is a reliable and valid measure of parenting behaviors for individuals who have a child with mental retardation living at home.

Group process and rating techniques were used to create a scale for measuring severity and frequency of 24 problem behaviors in institutionalized mentally retarded persons. A substantial correlation was found between scores and staff-time allocations, indicating usefulness of the scale as a predictor of staffing requirements for behavior…
