Three studies (N = 1,346) detail the development of three theoretically grounded instruments operationalizing "instructor strictness." Using open-ended questionnaire data (n = 427), study 1 inductively derives an understanding of the instructor behaviors that students perceive as strict. These patterns of behavior are then condensed into…

Background: Behavioral support may be effective in increasing physical activity (PA) in school settings. However, there are no data collection systems to concurrently record PA and behavioral support. This paper describes the development and validation of the System for Observing Behavioral Ecology for Youth in Schools (SOBEYS)--an instrument used…

Forty-four individuals, 18-47 (MN 21.8, SD 5.63) years of age, took part in a study examining the magnitude and direction of the relationship between self-report and direct observation measures of relaxation and mindfulness. The Behavioral Relaxation Scale (BRS), a valid direct observation measure of relaxation, was used to assess relaxed behavior…

Poor reciprocity is a defining feature of an autism spectrum disorder (ASD). In the current study, we examined the reliability and validity of the Interactive Drawing Test (IDT), a new instrument to assess reciprocal behavior. The IDT was administered to children and adolescents with ASD (n = 131) and to a typically developing group (n = 62). The…

The three algorithms most frequently selected by behavior-analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with…

A key feature of autism is restricted repetitive behavior (RRB). Despite the significance of RRBs, little is known about their phenomenology, assessment, and treatment. The Repetitive Behavior Scale-Revised (RBS-R) is a recently-developed questionnaire that captures the breadth of RRB in autism. To validate the RBS-R in an independent sample, we…

Studied whether pubertal timing by self-report (SR), parent report (PR), or physical examination predicted the same aspects of adjustment and behavior problems. Findings for 52 girls, 56 boys, and their parents show that pubertal timing by SR and PR did not always provide the same level of prediction as did physical examination. (SLD)

This study examined the sexual messages depicted in music videos aired on MTV, MTV2, BET, and GAC from August 2, 2004 to August 15, 2004. One-hour segments of music videos were taped daily for two weeks. Depictions of sexual attire and sexual behavior were analyzed via a four-page coding sheet (interrater-reliability = 0.93). Results indicated…

Many empirical studies have examined factors that influence ratings of performance. This study examined the rating variable performance of a single individual. Serial position of a single poor or good performance in a series of otherwise good or poor performances was manipulated to examine its effects on both ratings and recommended actions toward…

In this response to critiques (Mudford, Hogg and Roberts 1997, 1999) of the use of behavior states in research involving individuals with mental retardation, it is argued that the work on behavioral state analysis by Robert D. Guess has contributed to the field at the practical, empirical, and theoretical levels. (Contains references.) (CR)

Examines the tendency of observers to make less reliable recordings of behavorial events when a calibrating observer is absent. Using four different multicategory systems, 26 experienced observers coded 200 hours of videotaped family interactions. Concludes that observers lapse into a less attentive "set" prior to coding without a…

The reliability of visual inspection in single-case research was investigated by determining agreement among 5 judges visually inspecting 44 graphs depicting behavior from baseline to intervention. Agreement between visual inspection and statistical procedures was determined. Implications for single-case research are discussed. (SLD)

Responds to a critique by Mudford, Hogg, and Roberts (1997) that raised concerns about the observation code used in a longitudinal research project to assess emerging behavior state patterns in young children with disabilities. Concerns about the thoroughness of the reliability data collected by Mudford are discussed. (Author/CR)

This article critiques the research methodology used by Mudford, Hogg, and Roberts (1999) that resulted in a failure to achieve inter-observer agreement on adults with mental retardation when using an experimental, 13-category behavior state code. Arguments are provided on why their videotape study does not meet requirements of acceptable…

The objective of this paper is to report the development and use of an observation checklist to identify typically developing children with behavioural manifestations associated with inattention, hyperactivity and impulsivity. This measure is termed the Scope Classroom Observation Checklist (SCOC). The SCOC was developed, assessed for reliability…
