The rich technology of stimulus preference assessment (SPA) is a product of 40 years of experimental research. Basic principles of reinforcement and a modest empirical literature suggest that high-preference stimuli identified via SPA may enhance treatment efficacy and decrease problem behavior more effectively than less-preferred stimuli. SPAs…

The author was favorably impressed with the breadth, scope, and quality of the articles in this issue that dealt with the various aspects and correlates of social behavioral functioning as well as assessment and intervention considerations. Each of these articles dealt with a unique aspect of social behavioral functioning in children and youth and…

Background: The quality of behaviour support plans (BSPs) can be an important influence on the quality of the support provided to people with disability who show challenging behaviours. The Behavior Support Plan Quality Evaluation Guide II (BSP-QE II) is one tool that may be useful in assessing the quality of behaviour support plans. It has…

Background: Reliable measures of aggressive challenging behaviour are required if interventions aimed at reducing this behaviour among people with intellectual disability (ID) are to be formally evaluated. The present authors examined the reliability of the Modified Overt Aggression Scale (MOAS), an instrument not yet formally tested in those with…

This study addresses the questions that arise when collecting, describing, and analyzing information from multiple informants regarding attributes of individual students. Using data from the Fast Track study, we evaluate alternative measurement strategies for using multiple teacher ratings of student adjustment to middle school among a sample of…

A study tested the psychometric properties of the Stereotyped Behavior Scale, an empirically developed behavior rating scale for adolescents and adults with mental retardation. Forty-five adults with mental retardation and various rates of stereotypies participated. Results found the scale had high rates of reliability, validity, and interrater…

Standardized rating scales are the most often used part of the multidimensional assessment of children's behavior. However, low cross-informant correlations raise concerns about the reliability and validity of the resulting scores. This study examined whether the manner in which behavioral constructs are measured differs across informants, across…
