Development and Initial Validation of the Humor Climate in Sport Scale
2021
In sport teams, humor is an essential element that influences communication processes, and plays an important role in group dynamics. Despite this, no current instrument is presented in the literature to measure humor climate in sport teams. Therefore, the current study presents the development and initial validation of the Humor Climate in Sport Scale (HCSS). The aim was to assess content, structural and concurrent validity of the developed instrument, and to examine differential item functioning (DIF) as a function of sex. Three different phases were completed in this study. The first phase involved focus groups (n= 5) that explored humor as communication in a team sport context. In phase…
Test fairness: a DIF analysis of an L2 vocabulary test
2000
The purpose of this study is to analyse gender-uniform differential item functioning (DIF) in a second language (L2) vocabulary test with the tools of item response theory (the separate calibration t-method) and to study potential gender impact on the test performance measured by different item composites. The results of the study show that despite the fact that there are test items with indications of DIF in favour of either females or males, the test as a whole is not gender-biased. In spite of this, it was demonstrated that some item composites are gender-biased. In view of item bank building and use, it means that some of the tests constructed on the basis of an item bank might be bias…
Adaptation of a German Multidimensional Networking Scale into English
2011
Networking refers to building and maintaining personal contacts in order to obtain resources that, in turn, enhance one’s career success and work performance. This study reports the translation and adaptation of a multifaceted German networking scale ( Wolff & Moser, 2006 ) into English and focuses on the equivalence of the two language versions. Going beyond the often used translation-backtranslation method, we used a parallel translation-backtranslation method in combination with two expert committees to arrive at the English scale version, aiming to obtain at least structural equivalence. We utilize a bilingual sample (N = 76) as well as monolingual samples from the US (N = 174) and…
Development of Computerized Adaptive Testing for Emotion Regulation
2020
Emotion regulation (ER) plays a vital role in individuals’ well-being and successful functioning. In this study, we attempted to develop a computerized adaptive testing (CAT) to efficiently evaluate ER, namely the CAT-ER. The initial CAT-ER item bank comprised 154 items from six commonly used ER scales, which were completed by 887 participants recruited in China. We conducted unidimensionality testing, item response theory (IRT) model comparison and selection, and IRT item analysis including local independence, item fit, differential item functioning, and item discrimination. Sixty-three items with good psychometric properties were retained in the final CAT-ER. Then, two CAT simulation stud…
DIF in the Spanish Version of the Verbal Selective Reminding Test Using Samples From Hispanics in the United States, Mexicans, and Spaniards
2019
Before a test can be used in the target population, it is necessary to demonstrate that there is measurement equivalence. One way to do this is by studying differential item functioning. Objective: In this study, we used the Mantel-Haenszel procedure and logistic regression to analyze DIF in the Spanish version of the Verbal Selective Reminding Test between Spaniards, Mexicans and Hispanics in the United States. Method: Three balanced samples, matched by age, education and sex, were studied: Spaniards, Mexicans and Hispanics (616 healthy participants from Spain (n = 211), Mexico (n = 201) and the United States (n = 205). A six-trial version of the Spanish version of the Verbal Selective Rem…
Linguistic diversity and assessment in multilingual schools
2018
En un entorno en el que la diversidad lingüística es natural, la metodología de evaluación afronta nuevos retos. La equidad en el proceso evaluativo aconseja la consideración de aspectos relacionados con las características psicométricas de las pruebas, el desarrollo de la competencia lingüística, o el contexto sociolingüístico, a través de modelos explicativos sobre las variables contextuales de naturaleza lingüística que inciden en el rendimiento. Utilizando datos poblacionales de centros educativos de segundo curso de enseñanza secundaria obligatoria que ofertan más de un modelo lingüístico en la Comunidad Autónoma del País Vasco (N=45), este trabajo analiza las respuestas de 2783 estudi…
Dimensionality and Measurement Invariance of the Italian Version of the EORTC QLQ-C30 in Postoperative Lung Cancer Patients
2019
Background: This study aims to validate and evaluate the psychometric properties and measurement invariance of the Italian version of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30), which is a measure of quality of life (QoL) for lung cancer patients after surgery. Methods: A total of 167 lung cancer patients completed the Italian version of the EORTC QLQ-C30 questionnaire at 30 days after they received a lobectomy. The factor structure of this scale was assessed by performing confirmatory factor analysis (CFA). Measurement invariance was evaluated by considering differential item functioning (DIF) due to age, gender, a…
Psychometric Evaluation of the Norwegian Versions of the Modified Group Environment Questionnaire and the Youth Sport Environment Questionnaire
2021
This study aimed to translate the modified Group Environment Questionnaire (GEQ) and the Youth Sport Environment Questionnaire (YSEQ) into Norwegian, examine the factor structure and reliability of the scales through independent clusters model confirmatory factor analysis (ICM-CFA) and exploratory structural equation modeling (ESEM), and examine differential item functioning (DIF) as a function of sex. Three-hundred-and-thirty-three athletes (M(SD)age = 18.7(2.60) years; 33% females) completed the GEQ. Three-hundred-and-three athletes (M(SD)age = 15.0(1.48) years; 26% females) completed the YSEQ. Results indicated acceptable fit indices for a four-factor, a second-order two-factor (task a…
Evaluating Gender Differences in Problematic Smartphone Use
2022
Abstract. The Smartphone Addiction Inventory (SPAI) is widely used to measure problematic smartphone use (PSU). Although the SPAI has been translated and validated in different countries, its measurement invariance across gender has received little research attention. This study aimed to examine whether men and women interpreted the Italian version of the SPAI (SPAI-I) similarly and, consequently, whether the observed gender differences in SPAI scores, which have been shown in previous studies, could be due to true differences, rather than to differences in measurement. Six hundred nineteen Italian young adults ( Mage = 22.02 ± 2.63; 55.7% women) took part in the study and completed the SP…
