Perfectionism is a multidimensional personality characteristic associated with mental health problems. However, its features are commonly misunderstood, and many people are unaware of the risks it can pose. This study aimed to develop the first self-report measure of perfectionism literacy. That is, the degree of knowledge someone has about…

Purpose: The purpose of this study is to explore the role skepticism plays among adolescents' online information literacy skills. Design/methodology/approach: The authors provide the conceptual grounding to operationalize and measure the notion of skepticism in an online information literacy context. Inspired by an existing measure known as the…

Narcissism in social media reveals itself differently than in daily social interactions. Therefore, the present study aimed to develop a Scale of Narcissism in Social Media through the lens of the Narcissistic Admiration and Rivalry Model and to investigate its psychometric characteristics. The total sample of the study consisted of 740…

Motivation for reading is important to comprehension and has been studied extensively in offline reading contexts. However, little is known about the role of motivation in online reading, a new and increasingly important context for reading, largely because of a lack of valid and reliable instruments to estimate a student's motivation for online…

The present study aimed to empirically examine the validity of grit among language learners and its relation to vocabulary knowledge. Grit is defined as a trait that is characterised by a tendency to be passionate about and persevere towards the achievement of long-term goals. A newly developed questionnaire, L2-Grit Scale, which assesses…

The study aimed to explore the Chinese version of the Frost Multidimensional Perfectionism Scale suitable for gifted junior high school students and to classify the types of perfectionism. The Frost Multidimensional Perfectionism Scale was translated into Chinese to evaluate the factor structure and typology of academically gifted students in…

The dark core of personality is a recent construct that encompasses the malevolent, antagonistic, and aversive side of human nature that represents the common inner core of dark personality traits. The aim of the present study is to develop a short, multidimensional, and invariant version of the dark core of personality D70 measure. Two samples of…

Person misfit and person reliability indices in item response theory (IRT) can play an important role in evaluating the validity of a test or survey instrument at the respondent level. Prior empirical comparisons of these indices have been applied to binary item response data and suggest that the two types of indices return very similar results.…

Motivation for reading is important to comprehension and has been studied extensively in offline reading contexts. However, we know little about the role of motivation in online reading, a new and increasingly important context for reading. This is largely because we lack valid and reliable instruments to estimate a student's motivation for online…

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…

Social, emotional, and behavioral (SEB) skills comprise a broad set of abilities that are essential for building and maintaining relationships, regulating emotions, selecting and pursuing goals, or exploring novel stimuli. Toward an improved SEB skill assessment, Soto and colleagues recently introduced the Behavioral, Emotional, and Social Skills…

This paper documents the translation and adaptation of the "Career Adapt-Abilities Scale + Cooperation Scale" (CAAS + C; Savickas & Porfeli, 2015) to the Brazilian context and provides initial validity evidence for this instrument by testing its internal structure and exploring its relationships with external variables (i.e., Big…

Item response tree (IRTree) models are a flexible framework to control self-reported trait measurements for response styles. To this end, IRTree models decompose the responses to rating items into sub-decisions, which are assumed to be made on the basis of either the trait being measured or a response style, whereby the effects of such person…

The Frost Multidimensional Perfectionism Scale or FMPS is one of the first empirically validated measures of perfectionism. Cultural nuances demand that the efficiency of a short version of this scale, FMPS -- Brief, be tested on an Asian sample. Given the wealth of studies that consistently linked perfectionism to academic achievement, research…

Unfolding item response theory (IRT) models are important alternatives to dominance IRT models in describing the response processes on self-report tests. Their usage is common in personality measures, since they indicate potential differentiations in test score interpretation. This paper aims to gain a better insight into the structure of trait…
