This paper illustrates that the psychometric properties of scores and scales that are used with mixed-format educational tests can impact the use and interpretation of the scores that are reported to examinees. Psychometric properties that include reliability and conditional standard errors of measurement are considered in this paper. The focus is…

The aim of the present study was to evaluate the psychometric properties and factor structure of the Behavior Problems Inventory (BPI-01) in a community population. The Swedish version of the BPI-01 was administered by interviewing care staff of all adults (n = 915) with administratively defined intellectual disabilities (IDs) living in Orebro…

The study aimed to field-test a Greek version of the Wechsler Quicktest and to examine its psychometric properties. The Quicktest was individually administered to 208 students, aged 5-14 years, along with a reading test. Based on the Rasch analysis, data for the Quicktest subtests showed acceptable fit to the model. Also, correlations were found…

The present study employed the Disability Assessment Schedule (DAS) to assess problem behaviors in a large sample of adults with ID (N = 568) and evaluate the psychometric properties of this instrument. Although the DAS problem behaviors were found to be internally consistent (Cronbach's [alpha] = 0.87), item analysis revealed one weak item…

Objective: Sexually transmitted infections and the human immunodeficiency virus incidence rates remain high among college-aged individuals. This study examined the validity and reliability of the Multi-Factor Attitude toward Condoms Scale (MFACS). Participants: Participants were recruited from a large midwestern university during February and…

Objective: Develop and evaluate key psychometric properties of a self-report questionnaire specifically designed to assess student drinkers' self-confidence to employ a variety of strategies intended to reduce unhealthy consequences of high-risk drinking. Methods: Four hundred ninety-eight participants rated their confidence (from "not at all…

Purpose: This study investigated the psychometric properties of 2 oral language measures that are commonly used for diagnostic purposes with school-age children who have language impairments. Method: Two hundred sixteen children with specific language impairment were assessed with the Test of Language Development--Primary, Third Edition (TOLD-P:3;…

The construct of psychological flexibility (PF) is a central concept in acceptance and commitment therapy. It is defined as the process of contacting the present moment fully as a conscious human being and persisting in or changing behavior in the service of chosen values. PF is hypothesized to be an important aspect of healthy psychological…

Objectives: To carry out a preliminary exploration and measurement of therapy expectancy in adults with intellectual disabilities through the development and psychometric evaluation of the therapy expectation measure (TEAM). Design: The initial scale development phase combined top-down theory-driven and bottom-up data-driven processes to identify…

Validity evidence was gathered for the Academic Entitlement Questionnaire (AEQ). After reviewing entitlement literature, items were written to cover the breadth of academic entitlement. Results provide evidence for the substantive, structural, and external aspects of validity of the AEQ. Implications for research and use of the AEQ are discussed.…

Humphry (this issue) deserves credit for drawing attention to the long-neglected fact that differences in item discrimination parameters are often due to empirical factors and not the product of random error components. In doing so, Humphry offers a psychometrically elegant, coherent, and practically important new model that is more flexible while…

The present study examined the reliability and validity of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) for use with deaf and hard-of-hearing (D/HOH) children. Psychologists (n = 10) provided data for 128 D/HOH children who were assessed with the WISC-IV as part of routine assessments. All the WISC-IV subtests (8) 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…

The goal of this study was to develop and subsequently evaluate the internal construct and criterion-related validity of the Preschool Imitation and Praxis Scale (PIPS). Different task characteristics were selected considered to be important as unravelled in research in apraxic adults to tap a broad range of possible imitation mechanisms.…

Educational stakeholders have continued to express concerns over the poor academic performance of Nigerian students at virtually all levels of academic engagements. This paper investigated personal factors as predictors of students' academic performance in the South-Western Nigeria. The study employed the ex post facto design using a survey design…
