Background: The increasing number of individuals with an intellectual disability who are at risk of developing dementia highlights the need to use measures with strong psychometric properties as part of the screening, assessment and diagnostic process. Method: Searches were made of clinical and good practice guidelines and English language journal…

There is a need to promote growth past basic reading proficiency toward the more substantial idea of reading maturity. The reading maturity construct has a history of being valued, at least in principle. However, it is a complex construct, and this makes its measurement challenging. The present research study addressed aspects of this challenge by…

Measurement invariance is a prerequisite when comparing different groups of individuals or when studying a group of individuals across time. This assures that the same construct is assessed without measurement artifacts. This investigation applied a novel approach of simultaneous parameter linking to cross-sectional and longitudinal measures of…

For a multiple-choice test under development or redesign, it is important to choose the optimal number of options per item so that the test possesses the desired psychometric properties. On the basis of available data for a multiple-choice assessment with 8 options, we evaluated the effects of changing the number of options on test properties…

In this study, the author examined potential mediators of the negative relationship between the absolute difference in items' lengths and their inter-item correlation size. Fifty-two randomly ordered items from five personality scales were administered to 622 university students, and 46 respondents from a survey website rated the items'…

Participants of the study were 330 university students (232 females and 98 males) along with the age mean of 20.22 (SD=1.32). In order to validate the six factor structure of Mindful Self-care Scale, a confirmatory factor analysis was…

Introduction: International literature indicates that self-efficacy and resilience are interrelated and they both predict teachers' burnout and stress. In order to better understand their intertwining relationship, the present study was conducted to test the hypothesis that resilience mediates the effect of efficacy beliefs to burnout and stress.…

This article describes the development of a new questionnaire for assessing L2 learners' language attitudes. Drawing on theoretical work in the fields of social psychology and applied linguistics, the author reviewed the concept of (language) attitudes and contrasted them with the concept of (language) motivation. This thorough literature review,…

Background: Problem behaviours are common among people with intellectual disabilities (ID), but psychometrically evaluated instruments for assessing such behaviours are scarce. The present study evaluated the psychometric properties of the Neuropsychiatric Inventory--Intellectual Disability (NPI-ID). Method: We assessed 108 residents with…

Naturalistic developmental behavioral interventions for young children with autism spectrum disorder share key elements. However, the extent of similarity and overlap in techniques among naturalistic developmental behavioral intervention models has not been quantified, and there is no standardized measure for assessing the implementation of their…

Little is known about the specific manner in which students cope with academic failure. To address this gap, a new measure of failure-coping behaviour was developed and validated. Two hundred and thirty-eight undergraduate students completed a new measure of failure-coping behaviour, in addition to measures of failure appraisal, depressed mood,…

The present study aims to adapt the "Teacher Enthusiasm Scale" developed by Kunter, Frenzel, Nagy, Baumert and Pekrun (2011) to Turkish and carry out validity and reliability analyses for the Turkish version of the scale. Study group 1 consisted of teachers working in the province of Antalya in the 2019-2020 academic year. Linguistic…
