The development of the Problematic Series WatchingScale (PSWS)

Background and aims The goal of the present study was to create a short ProblematicSeries Watching Scale (PSWS). Methods On the basis of the six components model of Griffiths (2005), six items were identifiedcovering all components of problematic series watching. Confirmatoryfactor analyses were carried out on two independent samples (N1  = 366, N2  = 752). Results The PSWS has appropriate factor structure and reliability. Theamount of free time was not, but the series watching time was associatedwith PSWS scores. Women had higher scores than men. Discussion Before PSWS, no prior scale has been created to measure problematicseries watching. Further research is needed to properly assess itsvalidity and reliability; and for examining whether extensive serieswatching can lead to health-related and psychosocial problems. Conclusions In the increasingly digitalized world there are many motivationalforces which encourage people watching online series. In the lightof these changes, research on problematic series watching will beprogressively relevant

Functional gastrointestinal symptoms and increased risk for orthorexia nervosa

Purpose: Recent guidelines point out the possible risk for orthorexia nervosa in functional gastrointestinal disorders, however, to date, no study has investigated this association. The present study aimed to explore the potential relationship between irritable bowel syndrome-related functional gastrointestinal symptoms and certain maladaptive eating behaviours, such as symptoms of orthorexia nervosa and emotional eating. Methods: A sample of 644 Hungarian volunteers (Mage=22.37; SDage=3.95) completed a survey with the following questionnaires: the Rome IV Diagnostic Questionnaire (R4DQ) for adults—Irritable bowel syndrome module for the measurement of functional gastrointestinal symptoms, the Hungarian version of the ORTO-15 questionnaire (ORTO-11-Hu) to assess symptoms of orthorexia nervosa, the Three-Factor Eating Questionnaire (TFEQ) Emotional Eating subscale to measure symptoms of emotional eating and the Short Health Anxiety Inventory (SHAI) for the assessment of health anxiety. Spearman’s rank correlation was used to explore the associations between the measured variables, and structural equation modeling was used to test the proposed mediation models. Results: Functional gastrointestinal symptoms were positively related to symptoms of orthorexia nervosa and emotional eating. The relationship between functional gastrointestinal symptoms and symptoms of orthorexia nervosa was partially mediated by health anxiety, while the association between functional gastrointestinal symptoms and symptoms of emotional eating was partially mediated by symptoms of orthorexia nervosa. Conclusion: Our fndings highlight the possible risk for developing orthorexic symptoms in functional gastrointestinal symptoms, which could lead to other types of disordered eating patterns, such as emotional eating. The results also underscore the potential role of health anxiety in these relationships

Too many swipes for today: The Development of the Problematic Tinder Use Scale (PTUS)

Background and aims Tinder is a very popular smartphone-based geolocated dating application. The goal of the present study was creating a short Problematic Tinder Use Scale (PTUS). Methods Griffiths’ (2005) six-component model was implemented for covering all components of problematic Tinder use. Confirmatory factor analyses were carried out on a Tinder user sample (N = 430). Results Both the 12- and the 6-item versions were tested. The 6-item unidimensional structure has appropriate reliability and factor structure. No salient demography-related differences were found. Users irrespectively to their relationship status have similar scores on PTUS. Discussion Tinder users deserve the attention of scientific examination considering their large proportion among smartphone users. It is especially true considering the emerging trend of geolocated online dating applications. Conclusions Before PTUS, no prior scale has been created to measure problematic Tinder use. The PTUS is a suitable and reliable measure to assess problematic Tinder use

A Rövid Egyetemi Unalom Kérdőív faktorstruktúrája

Kutatásunk célja az volt, hogy – Pekrun, Goetz, Titz és Perry (2002) Teljesítmény Érzelmek Kérdőívét (Achievement Emotions Questionnaire, AEQ) felhasználva – megvizsgáljuk az Egyetemi Unalom Kérdőív faktorstruktúráját. A vizsgálatban 370 egyetemi hallgató vett részt, 87 férfi és 283 nő. A megerősítő faktorelemzés (CFA) szerint a kérdőív hosszabb verziója majdnem elfogadható modellilleszkedést mutat, azonban a rövid változat faktorstruktúrája teljes mértékben megfelel a követelményeknek. A kérdőív alapu

Four facets of Facebook Intensity - The development of the Multidimensional Facebook Intensity Scale

The aim of the present study was to create a short and valid questionnaire: the Multidimensional Facebook Intensity Scale (MFIS). In Study 1 (N = 512), we used exploratory structural equation modeling to explore the basic dimensions of everyday Facebook use. The results suggested four factors: persistence, boredom, overuse, and self-expression. The MFIS also had good reliability in terms of internal consistency and temporal stability. In Study 2 (N = 566), confirmatory factor analysis was conducted in order to assess the factor structure revealed in the previous study. The four-factor first-order and the second order model appeared to be adequate contrasting to the one factor model. Based on target coefficient the four-factor second-order model appears to be the most adequate. In Study 3 (N = 531), the convergent validity of the MFIS was examined in relation to Facebook addiction, Facebook passion, Online Sociability and different personality dimensions. The MFIS can predict Facebook-related activities as liking and posting better than previous Facebook scales. The results suggest that this questionnaire is able to reliably differentiate between different aspects of Facebook use intensity
