Trend scoring constructed response items (i.e. rescoring Time A responses at Time B) gives rise to two-way data that follow a product multinomial distribution rather than the multinomial distribution that is usually assumed. Recent work has shown that the difference in sampling model can have profound negative effects on statistics usually used to…

The typical process for assessing inter-rater reliability is facilitated by training raters within a research team. Lacking is an understanding if inter-rater reliability scores "between" research teams demonstrate adequate reliability. This study examined inter-rater reliability between 16 researchers who assessed fundamental motor…

Background: Appropriate supports and instructional practices contribute to the development of self-determination. Also, research shows that the promotion of skills related to self-determination has been linked to the achievement of desired outcomes over the different life stages. Advances in self-determination require the development of assessment…

Teacher preparation programs are increasingly expected to use data on preservice teacher (PST) skills to drive program improvement and provide targeted supports. Observational ratings are especially vital, but also prone to measurement issues. Scores may be influenced by factors unrelated to PSTs' instructional skills, including rater standards.…

In this secondary analysis of a previously conducted systematic review, we analyze social validity assessments in intervention research for transition-age autistic youth. Social validity is concerned with the acceptability of the intervention goals, the acceptability and feasibility of the intervention procedures, and the perceived importance of…

Educational researchers often need to construct precise and reliable measurement scales of complex and varied representations such as participants' written work, videoed lesson segments and policy documents. Developing such scales using can be resource-intensive and time-consuming, and the outcomes are not always reliable. Here we present…

Background: The status of the velopharyngeal mechanism can be inferred from perceptual ratings of specified speech parameters. Several studies have proposed the measure of an overall velopharyngeal composite score based on these perceptual ratings and have reported good validity. The Cleft Audit Protocol for Speech--Augmented (CAPS-A) is a…

Even when raters demonstrate agreement in the use of a measure, limited score variability or violation of often-ignored statistical assumptions can result in lower reliability estimates than intuitively expected. This article uses data drawn from two randomized controlled trials of schema therapy and cognitive behavioral therapy for the treatment…

We describe best practices in reporting reliability estimates in counseling research with consideration to precision, generalization, and diverse populations. We provide a historical context to reporting reliability estimates, the limitations of past practices, and new methods to address reliability generalization. We highlight best practices…

Traditional estimators of reliability such as coefficients alpha, theta, omega, and rho (maximal reliability) are prone to give radical underestimates of reliability for the tests common when testing educational achievement. These tests are often structured by widely deviating item difficulties. This is a typical pattern where the traditional…

The aims of this reliability generalization study were to provide the overall alpha values of the California critical thinking disposition inventory (CCTDI) total score and subscales scores and investigate the characteristics of the studies that may be associated with the variability in the reliability values of the CCTDI total score and subscales…

This study aimed to provide meta-analytic reliability information of the Columbia-Suicide Severity Rating Scale (C-SSRS). We implemented systematic search procedures to 35 eligible studies (N = 23,247; Mage = 26.74 years) that reported reliability estimates. The synthesized average values of Cronbach's alpha were 0.88 (95% CI [0.85, 0.92]) for the…

Scoring in creativity research has been a central problem since creativity became an important issue in psychology and education in the 1950s. The current study examined the psychometric properties of 27 creativity indices derived from summed and averaged scores using 15 scoring methods. Participants included 2802 middle-school students. Data…

Background/Context: Confirmatory factor analysis (CFA) model is a commonly adopted framework to estimate and test a measurement model. Once a well-fitting final CFA model is selected, the selected model may be used to test structural relationships of the latent constructs with other variables, to construct a test with desired reliability and…

We examined dimensionality and temporal stability of the Interpersonal Stress Scale-Counselor (ISS-C) scores in a sample of professional counselors (n = 518). Confirmatory factor analyses provided support for a four-factor model previously identified through exploratory factor analysis and a bifactor model. Using a randomized test-retest, temporal…
