Duker, Pieter C.; Sigafoos, Jeff – Research in Developmental Disabilities, 1998
The psychometric properties of the Motivation Assessment Scale were examined using 90 ratings of different problem behaviors among 86 individuals with mental retardation. Although reliability and internal consistency were generally poor, the results depended upon topographies of problem behavior and methods of calculation. The construct validity…

Sigafoos, Jeff; And Others – Research in Developmental Disabilities, 1994
Eighteen adolescents and adults with severe/profound intellectual disability were rated by two staff members using the Motivation Assessment Scale to identify variables maintaining their aggressive behaviors. Analysis of interrater reliability indicated that for some individuals the scale may not represent a feasible alternative to more formal…

Zarcone, Jennifer R.; And Others – Research in Developmental Disabilities, 1991
This replication study found that only 16 of 55 raters agreed on the category of reinforcement maintaining a disabled individual's self-injurious behavior after using the Motivation Assessment Scale. Additionally, only 15 percent of the correlation coefficients obtained were above 80 percent, and none of the reliability scores was above 80…

Parent and teacher ratings on the Aberrant Behavior Checklist with an outpatient sample of 110 children, adolescents, and young adults with mental retardation found that the 5-factor structure of both parent and teacher data corresponded very well with the 5 factors originally obtained from staff ratings of mentally retarded inpatients.

The applicability of the Children's Depression Inventory (CDI) (in the informant-rating version) to mentally retarded adults was evaluated with 798 individuals. Evaluation of internal consistency, interrater reliability, factor analysis, and effects of age, sex, and degree of mental retardation indicated that the CDI is suitable as a diagnostic…
