Although effective, humane treatments exist for persons with intellectual disabilities (ID) who have challenging behaviour, little research has examined the extent to which clients receive formal, documented vs. undocumented interventions. Caregivers (of 625 persons with ID living in community and institutional residences in Ontario, Canada) were…

The aim of this study was the preliminary development of a short 10-item version of the CiOQ. First, 10 items were selected on the basis of their high factor loadings in previously published work. Two studies are then reported. In Study 1, the 10 items were subjected to confirmatory factor analysis using data from a sample of college students…

This research describes efforts to develop and validate a multidimensional measure of the learning organization. An instrument was developed based on a critical review of both the conceptualization and practice of this construct. Supporting validity evidence for the instrument was obtained from several sources, including best model-data fit among…

In this article, we extend previous work with respect to interrater reliability measure of computer-mediated conferencing and suggest coding categories relevant to problem-based learning. Calculating interrater reliability agreement by using a Transcript Reliability Cleaning Percentage (TRCP) approach is simple for academics with limited…

Thirty-four undergraduates used Web-based self- and peer-assessment procedures for evaluating proposals in experimental psychology courses. Students presented their proposals and commented on the proposals of others on the Web. Results indicated that proposal observation and peer interaction enhanced the quality of students' proposals. These…

The Social Skills Rating System (SSRS; F.M. Gresham & S.N. Elliott, 1990) is a norm-referenced measure of students' social and problem behaviors. Since its release, much of the published reliability and validity evidence for the SSRS has focused primarily on the Teacher Report Form. The purpose of this study was to explore reliability and…

This article reports three studies in which a scale for assessing teachers' beliefs about professional-development initiatives was developed and its scores evaluated for reliability and validity. Results indicated that the Teachers' Attitudes About Professional Development (TAP) scale produced scores with high reliability, a stable one-factor…

The educational goals and objectives provide a reference for curriculum designers, teachers, and educators, and they are required for evaluation or accreditation processes. This article presents a systematic method to state the learning objectives and analyze the consistency of a secondary school science program developed in Spain. The method is…

Studies of self-induced vomiting of retarded persons have found that the rate of eating and the amount eaten alter this problem. The present study attempted to determine whether this same relationship was exhibited by the nonretarded bulimic. A nonretarded bulimic woman provided her subjective ratings of her desire to vomit after eating her taboo…

We evaluated the statistical power of single-indicator latent growth curve models (LGCMs) to detect correlated change between two variables (covariance of slopes) as a function of sample size, number of longitudinal measurement occasions, and reliability (measurement error variance). Power approximations following the method of Satorra and Saris…

This study reports on norms developed for the Minnesota Institute of Public Health's (1999) Community Readiness Survey. Prevention experts from ten states and the Red Lake Nation sorted data from 50 communities into high and low readiness groups using a Q-sort process. High inter-rater agreement was achieved on communities sorted. Tests of…

Responses to the 1999 Youth Risk Behavior Survey including suicide ideation, attempt, medically treated attempt, and six problem behaviors were analyzed. Youth across the spectrum ideated. Overwhelmingly, the 17% of youth with more than three problem behaviors were the youth who acted; they accounted for 60% of medically treated suicidal acts.…

The Preferred Items and Experiences Questionnaire (PIEQ) is a new instrument to assess reinforcer preferences in adolescents and adults. Research was conducted with college and high school students to develop the PIEQ, to examine its reliability with test-retest and internal consistency methods, and to test its validity. This research provides…

Pedagogical agents are gaining acceptance as effective learning tools (Baylor & Ryu, 2003; Moreno, Mayer, Spires & Lester 2001; Moreno, 2004). The increase in the use of agents highlights the need for standardized measurements for evaluating user performance in these environments. While learning gains are a primary variable of interest in such…

Tables permitting the conversion of short-form composite scores to full-scale IQ estimates have been published for previous editions of the Wechsler Adult Intelligence Scale (WAIS). Equivalent tables are now needed for selected subtests of the WAIS-III. This article used Tellegen and Briggs's formulae to convert the sum of scaled scores for four…
