With the advent of big data and advances in technology, psychological assessments have become increasingly sophisticated and complex. Nevertheless, traditional psychometric issues concerning the validity, reliability, and measurement bias of such assessments remain fundamental in determining whether score inferences of human attributes are…

The goal of this paper is to examine the psychometric properties of a live-coded behavioral measure of joint attention, the "Attention-Following and Initiating Joint Attention Protocol" (JA Protocol), in order to assist researchers and clinicians in identifying when this measure may meet their joint attention assessment needs. Data from…

School climate measurement is a long-standing topic in educational research. This review article provides an overview and appraisal of school climate measures published between 2003 and 2013 in scientific journals. A search for published school climate instruments for secondary school students was made in three databases. Twelve articles meeting…

This brief provides tips for forming a team of staff and consultants with the needed expertise to make key measurement decisions that will ensure high-quality data for answering the study's research questions. The brief outlines the main responsibilities of measurement team members. It also describes typical measurement tasks and discusses…

The reliability of a new scale to assess Autistic Disorder, Pervasive Developmental Disorder, Not Otherwise Specified (PDD-NOS), and Asperger's Disorder in children was examined. Parents or other caregivers rated symptoms of 207 children between 2 and 16 years of age. The scale, which had 40 items in the final version, correlated highly with…

Research has consistently shown that principal leadership matters for successful schools. Evaluating principals on the behaviors shown to improve student learning should be an important leverage point for raising leadership quality. Yet principals are often evaluated with the use of instruments with no theoretical background and little, if any,…

This study establishes the reliability and validity of the Law Enforcement Officer Stress Survey (LEOSS), a short early-warning stress-screening measure for law enforcement officers. The initial phase of LEOSS development employed the behavioral-analytic model to construct a 25-item instrument specifically geared toward evaluation of stress in…

This article examines available measures of perceived teacher support and presents findings from two studies exploring the psychometric properties of the Teacher Support Scale (TSS). In Study 1, an exploratory factor analysis suggested a hierarchical structure with four first-order factors (Invested, Positive Regard, Expectations, and Accessible…

Early identification of social-emotional behavioral problems in infants and preschoolers is critical. Nine parent-report and caregiver/teacher-report instruments measuring preschool social-emotional behavioral problems and strengths are reviewed. Advantages to the use of parent-report and caregiver/teacher-report instruments are that they are easy…

Development of the Stereotyped Behavior Scale for adolescents and adults with mental retardation is described. Use with 600 individuals resulted in refinement and a 26-item scale with an internal consistency alpha of 0.88, test-retest reliability of p=0.90, and interrater reliability of p=0.76. (DB)

The Quebec Adaptive Behavior Scale (QABS) is widely used in Quebec (Canada) to assess behavior of people with mental retardation in educational, vocational, residential or hospital settings. This study estimated the interrater agreement and test-retest reliability of the QABS. To determine test-retest reliability, the QABS was completed by 27…

Administered three Wechsler adult intelligence scales to 72 undergraduates and tested the quality of means, variances, and covariances, utilizing subtest scale scores and IQs. Results indicated that the three scales were not parallel. Generally, the subtest scaled scores exhibited less similarity across the three scales than the IQ estimates.…

Twenty-one language tests that included norms for children ages 4 and 5 were reviewed for information on 10 psychometric criteria. Administration of the 4 tests meeting the most criteria to 20 preschool children with specific language impairments and 20 controls found that only 1 (the Structured Photographic Expressive Language Test) provided…

A study of 83 people working in the field of autism evaluated the psychometric properties of the Autism Survey, an instrument to assess respondents' knowledge about autism. The survey was found to measure one factor, to be stable across time, and to have an internally consistent total score. (Author/CR)

The Swedish version of the Communication Strategies scale of the Communication Profile for the Hearing Impaired was evaluated in terms of descriptive statistics, corrected item-total correlations, principal component analysis, and internal consistency reliability. The study concludes that the scale is an adequately reliable and clinically useful…
