This study aims to present the psychometric properties of the Polish language version of the Mathematical Resilience Scale (MRS; Kooken et al., 2016), established in a sample of 443 adults. We confirmed the first-order three-factor structure (Value, Struggle, Growth) with the second-order factor (Total Mathematical Resilience) of the MRS and its…

Programming aimed at promoting positive student mental health and reducing or preventing mental-ill health is common within schools in Ontario. A brief, valid, and scalable measure was needed to assess the organizational conditions, or the capacity, readiness, and resources of schools to successfully implement and sustain this programming. In…

Background: Community participation is considered a fundamental aspect of quality of life and one of the essential goals of services for people with intellectual disabilities, yet there is no agreed way of measuring community participation. Method: Two systematic searches were performed across eight electronic databases to identify measures of…

This note discusses the merits of coefficient alpha and their conditions in light of recent critical publications that miss out on significant research findings over the past several decades. That earlier research has demonstrated the empirical relevance and utility of coefficient alpha under certain empirical circumstances. The article highlights…

Past research suggests revised parallel analysis (R-PA) tends to yield relatively accurate results in determining the number of factors in exploratory factor analysis. R-PA can be interpreted as a series of hypothesis tests. At each step in the series, a null hypothesis is tested that an additional factor accounts for zero common variance among…

The positive manifold--the finding that cognitive ability measures demonstrate positive correlations with one another--has led to models of intelligence that include a general cognitive ability or general intelligence (g). This view has been reinforced using factor analysis and reflective, higher-order latent variable models. However, a new theory…

The current study sought out to advance the Social Self-Efficacy and Social Outcome Expectations scale using multiple approaches to scale development. Data from 583 undergraduate students were used in two scale development approaches: Classic Test Theory (CTT) and Item Response Theory (IRT). Confirmatory factor analysis suggested a 2-factor…

There is a clear need for highly competent health sciences experts. No instrument currently exists for assessing the generic competences of health sciences students. The aim of this study is to develop and psychometrically test the Health sciences Generic Competence (HealthGenericCom) instrument. The instrument development four step process has…

Despite several psychometric advantages over the 50-item Autism Spectrum Quotient, an instrument used to measure autistic traits, the abridged AQ-28 and its cross-cultural validity have not been examined as extensively. Therefore, this study aimed to examine the factor structure and measurement invariance of the AQ-28 in 818 Dutch (M[subscript…

Background: As delays or disorders in early language and communication are the most prevalent symptom in children with disabilities, early screening is crucial to promote prevention, early diagnosis, and intervention. However, to the best of our knowledge, no screening tool is available for the joint assessment of early language and social…

This article reports on the development and validation of the Instrumental Practice Goal Realization Inventory (IPGRI) designed to assess the process of self-directed study, beginning with setting the intention to practice and ending with the evaluation of one's performance. This new tool is based on the theoretical model of action phases. The…

This review is aimed at identifying assessment instruments used to measure treatment outcomes in children with autism spectrum disorder who received early and intensive behavioral interventions. Forty three articles were included and appraised using the Council for Exceptional Children's Standards for Evidence Based Practice quality index rater.…

Science identity, encompassing perceptions of competence, interest, and recognition in science, alongside learning self-efficacy reflecting confidence to master science skills, are key drivers of outcomes. However, developmental patterns likely vary across contexts. Participants were 512 Chinese students spanning grades 1-3 who completed the…

Professional success depends on more than just academic achievements frequently defined and evaluated as grades, academic averages and approval of semesters. Other non-cognitive factors, such as 'grit', or academic persistence, have been related to a decrease in academic dropout and success prediction. But it has not been measured in medical…

Plausibility perceptions about climate change influence learner engagement, motivation, and knowledge acquisition, thereby shaping the effectiveness of climate change education. The Plausibility Perception Measure (PPM) was originally developed following the Fourth Assessment Report of the Intergovernmental Panel on Climate Change in 2007. There…
