The main aim of this study is to develop a useful, valid, and reliable two-tier proportional reasoning skill test for middle school 7th and 8th-grade students. The research was carried out using the sequential explanatory mixed method. The study group of this research comprised of 391 (n[subscript 7th-grade]=223, n[subscript 8th-grade]=168)…

The study aimed to explore the factor structure and psychometric properties of the Chinese version of the Family Resilience Assessment Scale for Children with Disabilities (FRAS-CWD). Due to the complexity of family resilience and the particularity of disabilities, there is a lack of reliable and valid tools to evaluate family resilience for…

In line with the journal volume's theme, this essay considers lessons from the past and visions for the future of test validity. In the first part of the essay, a description of historical trends in test validity since the early 1900s leads to the natural question of whether the discipline has progressed in its definition and description of test…

The purpose of the current study was to explore the scientific utility of two behavior analytic assessments (i.e., progressive ratio and demand assessments) for psychotropic medication evaluation.

Autonomy describes cognition or behavior that is self-directed, according to personal interests, and free from external influence. This construct is of importance to students who are deaf because it has been shown to be positively related to their post-school transition outcomes, and this population faces unique challenges in this area. To conduct…

Individuals who require augmentative and alternative communication (AAC) comprise a heterogeneous group, but all need follow-up to assure the appropriateness of implemented interventions. To enable this, outcome measures such as the Family Impact of Assistive Technology Scale for Augmentative and Alternative Communication (FIATS-AAC) may be used.…

Background: Families of children with disabilities often face unique challenges. Developed in a U.S. context, the Beach Center Family Quality of Life measure assesses the effectiveness of supports and services that families receive. This study examines whether items from three sub-scales of the Beach Center instrument perform similarly for two…

Purpose: The purpose of this study was to evaluate the measurement structure of a simplified version of the "Multiple Sclerosis Self-Management Scale" (MSSMS) in a sample of 256 individuals with multiple sclerosis (MS). Methods: Exploratory factor analysis was utilized to uncover meaningful and interpretable factors. Results: The study…

Objective: To evaluate the measurement structure of the "Job Satisfaction of Persons with Disabilities Scale" (JSPDS) in a sample of employed U.S. Americans with disabilities.

The "Rating Scale of Impairment" (RSI; Goldstein & Naglieri, 2016b) is a norm-referenced measure of functional impairment. The RSI measures impairment in six domains, as well as overall impairment, based in part on the International Classification of Functioning, Disability, and Health. Functional impairment, as defined by the ICF…

Concepts such as participation and environment may differ across cultures. Consequently, to use a measure like the Young Children's Participation and Environment Measure (YC-PEM) in other than the original English-speaking contexts, cultural adaptation needs to be assured. The objective is to cross-culturally translate, adapt, and pilot test the…

Background: In education, Information and Communication Technology (ICT) has gone from being a convenient option to a permanent necessity. For students and people with functional diversity, it is of seminal importance. It is therefore worth learning how professionals perceive digital tools and apps for people and students with functional diversity…
