The Multidimensional Personality Questionnaire (MPQ) measures a wide range of personality traits associated with affect and temperament. However, the lengthy administration time may have hindered its widespread use in personality research.

The objective of the present research is to examine the factor structure of the Interpersonal Behavior Questionnaire (IBQ) and the Interpersonal Behavior Self Questionnaire (IBQ-Self) in the sport context. Confirmatory factor analyses were used to assess the psychometric properties and measurement invariance across sex and sports. For the IBQ, a…

This study tested factorial structure, reliability as well as gender, age, and cultural measurement invariance of the Brief Inventory of Thriving (BIT). Data were collected from 981 Italian, Portuguese, and Chinese emerging adults. Results showed that BIT scores were reliable, mono-dimensional, and suitable to assess thriving across different…

Purpose: To examine the factor structure and measurement invariance of the Körperkoordinations Test Für Kinder (KTK) and covariates of motor competence in a sample of Iranian children aged 5-14 years. Methods: Participants were children aged 5-14 years (N = 432, 61% boys). Age, sex, and body mass index were collected. Confirmatory factor analysis…

Little is known about whether a widely used mindfulness measure in adults--the Five Facet Mindfulness Questionnaire (FFMQ)--is also reliable and valid in adolescents. The current study evaluated the psychometric properties of a 20-item short-form FFMQ in a sample of 599 high school students (M[subscript age] = 16.3 years; 49% female) living in the…

Sense of coherence (SOC) is a relevant contributor and predictor of the individuals' mental and physical health. There are a number of studies about SOC, but only two validation articles of the sense of coherence scale (SOCS) were found on adolescents and none on children. The aim of this research was to validate the SOC scale in youth under 18.…

The Abbreviated Math Anxiety Scale (AMAS) is commonly used to compare groups on math anxiety. Group comparisons should however be preceded by a demonstration of metric and scalar measurement invariance, which is currently only available for undergraduate students in the USA. This study tested for metric and scalar measurement invariance of AMAS…

We developed and validated the Family Reminiscence Scale (FARS) in which adults rate their frequency of reminiscing with their parents about childhood experiences. In three studies, we characterized how FARS was related to adults' recollections of their earliest memories in different cultural contexts. First, we examined the factorial structure of…

The psychometric properties of the French version of the Trait Emotional Intelligence Questionnaire--Child Short Form (TEIQue-CSF) were investigated in a sample of 556 children 9 to 13 years of age. The internal consistency and temporal stability were satisfactory. A significant difference for gender, but not for age, was observed. With regard to…

This study assesses the utility of the U.S. version of the Strengths and Difficulties Questionnaire (SDQ) teacher form as a screener for mental health and behavior concerns. The SDQ was administered to a community sample of 391 culturally and linguistically diverse students in grades K-6. Internal reliability was assessed using Cronbach's alpha.…

Readiness is important for the success of the e-learning process. The purpose of this study was twofold: to develop a scale to measure K-12 teachers' e-learning readiness, and to examine their readiness to teach online. The participants were 3,295 K-12 teachers working in Izmir, Turkey. First EFA, then CFA-SEM was performed. Additionally,…

This research aimed to adapt and psychometrically examine the Multidimensional Perceived Autonomy Support Scale in Physical Education in the Spanish context. The participants were 560 (264 men and 296 women; M[subscript age] = 14.49, SD[subscript age] = 1.05) physical education secondary school students. The results underpinned a 15-item…

To examine reliability, validity, factor structure, and measurement invariance (i.e., configural, metric, and scalar invariance) of the Japanese Conners' Adult attention deficit hyperactivity disorder (ADHD) Rating Scales (CAARS), Japanese nonclinical adults (N = 786) completed the CAARS Self-Report (CAARS-S). Each participant was also rated by…

The "About Me" Questionnaire (AMQ) has been used to measure components of social identity, academic self-concept and self-worth in children and adolescents in the United Kingdom and abroad. Studies have reported simple reliability statistics but a comprehensive assessment of the scale's psychometric properties has not been conducted.…
