To measure individual difference in latent attributes more precisely, this study proposed a new cognitive diagnosis model (CDM), which is referred as the probabilistic-inputs, noisy conjunctive (PINC) model, by treating the deterministic binary latent attributes as probabilistic, and directly estimating the probability in the model. Simulation…

The aim of this study was to develop a measurement approach to assess the learning opportunities provided by parents to their young children with autism spectrum disorder during a free play task and to examine the relationship between learning opportunities and child performance on measures of cognition, autism spectrum disorder symptoms, and…

The current study aimed to adopt and assess the psychometric properties and measurement invariance of Grit-S among Omani and American students (N = 487) using Exploratory Factor Analysis (EFA) and Multi-Group Confirmatory Factor Analysis (CFA).

Aim: To evaluate the psychometric properties of a new measure of school belonging. Rationale: The sense of belonging to the school (organisation) as opposed to individuals within a school (peers) plays a significant part in pupils' behaviour and wellbeing. To date, few psychometrically robust, theoretically driven and brief scales exist.…

A key component of delivering mental health services involves evaluating psychosocial impairments linked to mental health concerns. Youth may experience these impairments in various ways (e.g., dysfunctional family and/or peer relationships, poor school performance). Importantly, youth may display symptoms of mental illness without co-occurring…

This article reports the development and psychometric properties of visions about future (VAF), an instrument assessing hope, optimism, and pessimism. Three different studies involving Italian adolescents were conducted. With the first study 22 items were developed and the factor structure was verified. The second study, involving a second sample…

In the United States, students have historically taken large-scale assessments for many different purposes. One purpose that is shared with many other countries is a desire to monitor aggregate trends in educational attainment in core subject domains such as literacy, mathematics, and science. In this commentary, the author examines testing,…

This study examined the psychometric properties of the German version of the Teacher Inclusive Education Self-Efficacy Scale (TIESES). Five hundred and nineteen teacher education students from Austria and 765 teacher education students from Germany participated in the study. Results of a multiple-group confirmatory factor analysis (for the two…
