The Effect of Some Environmental Factors on Interobserver Agreement.
Peer reviewed Peer reviewed
Fradenburg, Linda A.; And Others – Research in Developmental Disabilities, 1995
This study, involving five college students observing behavior of individuals with mental retardation, found that interobserver agreement was better in the presence of certain stimuli (such as when the subject's peers were present versus when they were not). Of 10 additional variables thought to potentially affect agreement scores, 1 (can't see,…

Evaluating Facilitated Communications of People with Developmental Disabilities.
Peer reviewed Peer reviewed
Szempruch, Joseph; Jacobson, John W. – Research in Developmental Disabilities, 1993
A quasi-experimental message-passing procedure was used to assess the validity of facilitated communication (FC) with 23 people with severe to profound mental retardation. No subject was able to accurately label or describe objects with facilitation. Possible reasons for findings set forth by proponents of FC and consistency with the emerging…

Descriptive Analysis of Multiple Response Topographies of Challenging Behavior across Two Settings.
Peer reviewed Peer reviewed
Emerson, Eric; And Others – Research in Developmental Disabilities, 1995
Time-based lag sequential analyses were conducted on 23 topographies of challenging behavior shown by 5 young people with severe mental retardation across 2 settings. Potential behavioral functions were identified for 21 of the 23 behaviors. Response classes were identified for four participants. Cross-validation with brief experimental analyses…

Validity of Greenspan's Models of Adaptive and Social Intelligence.
Peer reviewed Peer reviewed
Mathias, Jane L.; Nettelbeck, Ted – Research in Developmental Disabilities, 1992
Two studies assessed the construct validity of Greenspan's models of adaptive and social intelligence with 75 adolescents with mental retardation. Factor analysis measures of conceptual intelligence, adaptive behavior, and social intelligence yielded a practice-interpersonal competence construct. The second study, however, failed to establish the…

Response to Mathias and Nettelbeck on the Structure of Competence: Need for Theory-Based Methods to Test Theory-Based Questions.
Peer reviewed Peer reviewed
Greenspan, Stephen; McGrew, Kevin S. – Research in Developmental Disabilities, 1996
This paper responds to a 1992 study in which it was argued that the structure of intelligence in adults with severe mental retardation deviates from Greenspan's model, in which social and practical intelligence form separate factors. Application of confirmatory factor analysis to the original correlation matrix found the Greenspan model to be…

A Reply to Greenspan and McGrew's "Need for Theory-Based Methods to Test Theory-Based Questions."
Peer reviewed Peer reviewed
Mathias, J. L.; And Others – Research in Developmental Disabilities, 1996
This paper discusses inconsistencies in Greenspan and McGrew's argument that confirmatory, rather than exploratory, factor analysis should be utilized in testing Greenspan's model of adaptive intelligence in adults with severe mental retardation. It is argued that problems with the data set should be addressed through further research rather than…
