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…

In 2008, the "Journal of Positive Behavior Interventions" ("JPBI") celebrated 10 years in publication. As the flagship journal of positive behavior support (PBS), it is important to periodically examine the research published in "JPBI" to determine whether it reflects the basic principles of PBS, to explore the ways in which PBS is being…

Agreement among informants' ratings of children's and adults' internalizing and externalizing problems is moderate. Each informant contributes unique information about an individual's problems. Thus, it has been advocated to obtain ratings from multiple sources in child psychiatry, whereas adult psychiatry relies mostly on self-reports.…

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…

Early intensive behavioral intervention (EIBI) is a well-established treatment for children with autism spectrum disorders (ASD) and is thus widely recommended. However, the content of EIBI programs presumably varies considerably and may not always be tailored to the individual strengths and deficits of each child. Few assessment tools exist (and…

This article reports three studies that evaluated the test-retest and inter-rater reliability of the "Preschool Behavioral and Emotional Rating Scale" (PreBERS) (Epstein & Synhorst, 2009). First, teachers rated 63 children receiving school services for disability on the PreBERS, with two ratings one month apart. Second,…

This study examined the psychometric properties of the Revised Edition of the School Observation Coding System (REDSOCS). Participants were 68 children ages 3 to 6 who completed parent-child interaction therapy for Oppositional Defiant Disorder as part of a larger efficacy trial. Interobserver reliability on REDSOCS categories was moderate to…

Recently, several instruments have been developed to measure the subjective component of the quality of life (QOL) of people with profound intellectual and multiple disabilities (PIMD). A next step, however, must be the further validation of these instruments. The present study aimed at evaluating the psychometric properties of one of these…

Visual inspection is the primary method used to analyze graphed behavioral data produced by functional analyses of problem behavior. The purpose of this study was to examine rater reliability of functional analysis graphs using visual inspection. Forty-three participants responded to a one-time anonymous survey (N = 454) mailed to graduate…

The psychometric properties of a German version of the Questions About Behavioral Function Scale (QABF) (Matson & Vollmer, 1995) were examined in a sample of 522 individuals with intellectual disabilities residing in large facilities participated. The factor structure was first examined by exploratory factor analysis, yielding a…

Problem behavior is a major barrier to successful community integration for people with developmental disabilities. Recently, there has been increased interest in identifying contextual factors involving setting events and discriminative stimuli that impact the display of problem behavior. The authors previously developed the "Contextual…

Standardized rating scales remain the primary mechanism through which child behaviors are recorded. Despite the many advantages of such systems, the documented lack of agreement among different informants' ratings of the same child remains a pervasive problem for clinicians. This study examines the degree to which observed behavior ratings were…

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…

The current study examined the initial psychometrics of the "Early Childhood Behavior Problem Screening Scale" (ECBPSS; Epstein & Nelson, 2006), namely the factor structure and associated internal consistency of factor items of parent and teacher versions as well as interrater reliability. Data came from samples of preschool- and…

Genetically informative data can be used to address fundamental questions concerning the measurement of behavior in children. The authors illustrate this with longitudinal multiple-rater data on internalizing problems in twins. Valid information on the behavior of a child is obtained for behavior that multiple raters agree upon and for…
