Autism spectrum disorder (ASD) is currently one of the most researched of all childhood developmental disorders and is receiving attention in many domains. The purpose of this study was to design and provide psychometric evidence for a scale that measures police officer self-efficacy for working with individuals with ASD. Psychometric properties…

In education research test scores are a common object of analysis. Across studies test scores can be an important outcome, a highly predictive covariate, or a means of assigning treatment. However, test scores are a measure of an underlying proficiency we can't observe directly and so contain error. This measurement error has implications for how…

In standardized educational testing, test items are reused in multiple test administrations. To ensure the validity of test scores, the psychometric properties of items should remain unchanged over time. In this article, we consider the sequential monitoring of test items, in particular, the detection of abrupt changes to their psychometric…

Maladaptive perfectionism has a documented association with mental health problems, yet the context of maladaptive perfectionism (i.e., the domain where individuals exhibit such a trait) is rarely considered. This study aimed to develop a measure for academic perfectionism among college students and assess its psychometric properties. Five hundred…

Adaptive measurement of change (AMC) is a psychometric method for measuring intra-individual change on one or more latent traits across testing occasions. Three hypothesis tests--a Z test, likelihood ratio test, and score ratio index--have demonstrated desirable statistical properties in this context, including low false positive rates and high…

This article presents art as a tool for promoting mental health in schools by examining the effects of art making in a sample of 104 school-based mental health professionals. It unites findings from unrelated disciplines to derive and test a new conceptual framework proposing that active engagement in a visual-tactile process over time mediates a…

Hate speech has become a widespread phenomenon, however, it remains largely unclear why adolescents engage in it and which factors are associated with their motivations for perpetrating hate speech. To this end, we developed the multidimensional "Motivations for Hate Speech Perpetration Scale" (MHATE) and evaluated the psychometric…

Purpose: This exploratory study sought to establish the psychometric stability of a dynamic norming system using the Systematic Analysis of Language Transcripts (SALT) databases. Dynamic norming is the process by which clinicians select a subset of the normative database sample matched to their individual client's demographic characteristics.…

Emotion dysregulation is common among autistic people, yet few measures have received psychometric evaluation in this population. We examined the factor structure, reliability, and validity of a commonly-used measure of emotion dysregulation, the "Difficulties with Emotion Regulation Scale" ("DERS"), in a sample of 156 autistic…

The purpose of this study is to develop and examine the psychometric properties of the Online Course Overload Indicator (OCOI) and the Student Mental Fatigue Survey (SMFS). The OCOI was designed to measure students' perceptions of cognitive overload in online courses. The SMFS was used to assess students' perceptions of mental fatigue while taking…

This exploratory mixed method research aimed to develop parent and child forms of a scale to measure parents' practices to reward and punish their children. For the qualitative strand, semi-structured interviews were conducted with parents (n = 54) and their children (n = 39). The qualitative analysis revealed four major themes regarding parental…

This paper describes the benefits of a psychometric analytic approach when studying students' ability to comprehend texts. A reading comprehension measure consisting of four text passages with 32 questions was developed, and analyses using a mean-based approach and linear logistic test (LLTM) method were performed. According to ANOVA, eighth-grade…

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 current concept of inclusive education brings to light the need for assessment of pre-service and in-service teachers' attitudes towards inclusion, as they are essential agents to achieve full educational inclusion. The present study aimed to adapt a simple unidimensional tool to assess attitudes towards inclusion, the TAI scale. A total of…

With the increasing importance of Computational Thinking (CT) at all levels of education, it is essential to have valid and reliable assessments. Currently, there is a lack of such assessments in upper primary school. That is why we present the development and validation of the competent CT test (cCTt), an unplugged CT test targeting 7-9 year-old…
