Gaming-contingent self-worth, gaming motivation, and Internet Gaming Disorder

The relationship between problematic gaming behavior and self-esteem is well-documented (King & Delfabbro, 2014). Moreover, the basic needs component of Self-Determination Theory has also been proposed as an organizing framework to understand gaming motivation (Lafreniere, Verner-Filion, & Vallerand, 2012; Ryan, Rigby, & Przybylski, 2006). Building on these ideas, the current study describes the development of a measure of contingent self-worth (Crocker, Luhtanen, Cooper, & Bouvrette, 2003; Crocker & Wolfe, 2001) specific to gaming experiences within Massively-Multiplayer Online Role Playing Games (MMORPGs), and explores the association between Gaming-Contingent Self-Worth (GCSW) and symptoms of Internet Gaming Disorder (IGD). A sample of MMORPG players was recruited through Amazons Mechanical Turk (nź=ź600) to evaluate the reliability and validity of a GCSW scale. Exploratory and confirmatory factor analysis was used to identify a 29-item measure comprised of four components, including validation seeking, reward orientation, competition focus, and detachment. Additional analyses supported the hypothesis that GCSW is a strong predictor of IGD symptoms, beyond the contribution of motivation based on behavioral activities within the game. A measure of Gaming-Contingent Self-Worth (GCSW) is developed.Factors of GCSW include validation seeking, reward orientation, competition focus, and detachment.Associations between GCSW and Internet Gaming Disorder (IGD) are explored.GCSW predicts IGD beyond behavioral motives, weekly hours, and global self-esteem.

Measurement Invariance of the Internet Gaming Disorder Scale–Short-Form (IGDS9-SF) Between Australia, the USA, and the UK

The Internet Gaming Disorder Scale–Short-Form (IGDS9-SF) is widely used to assess Internet Gaming Disorder behaviors. Investigating cultural limitations and implications in its applicability is imperative. One way to evaluate the cross-cultural feasibility of the measure is through measurement invariance analysis. The present study used Multigroup Confirmatory Factor Analysis (MGCFA) to examine the IGDS9-SF measurement invariance across gamers from Australia, the United States of America (USA), and the United Kingdom (UK). To accomplish this, 171 Australian, 463 USA, and 281 UK gamers completed the IGDS9-SF. Although results supported the one-factor structure of the IGD construct, they indicated cross-country variations in the strength of the relationships between the indicators and their respective factor (i.e., non-invariant loadings of items 1, 2, 5), and that the same scores may not always indicate the same level of IGD severity across the three groups (i.e., non-invariant intercepts for items 1, 5, 7, 9).

The longitudinal association between anxiety and Internet addiction in adolescence: The moderating effect of classroom extraversion

Background and aims The risk effect of anxiety on addictive behaviors, including Internet addiction (IA), has repeatedly been highlighted in the international literature. However, there is a lack of longitudinal studies examining this association in relation to proximal context effects, particularly in adolescence. Such findings would shed light on potential age- and proximal context-related variations in the anxiety–IA association that could better inform IA prevention and intervention initiatives. Methods In this study, 648 adolescents, embedded in 34 classrooms, were assessed at the age of 16 and again at the age of 18 to examine the effect of anxiety on IA behaviors in relation to the average level of classroom extraversion. IA was assessed with the Internet Addiction Test (Young, 1998), anxiety with the relevant subscale of the Symptom Checklist 90 – Revised (Derogatis & Savitz, 1999) and classroom extraversion with the synonymous subscale of the Five Factor Questionnaire (Asendorpf & van Aken, 2003). A three-level hierarchical linear model was calculated. Results The present findings demonstrated that: (a) higher levels of anxiety were significantly associated with higher IA behaviors, (b) the strength of this association did not vary over time (between 16 and 18 years old), and (c) however, it tended to weaken within classrooms higher in extraversion. Discussion This study indicated that the contribution of individual IA risk factors might differently unfold within different contexts.

Item response theory analysis of the recoded Internet Gaming Disorder Scale-Short-Form (IGDS9-SF)

Based on the nine criteria for Internet gaming disorder (IGD) in DSM-5, the Internet Gaming Disorder Scale 9-Short Form (IGDS9-SF; Pontes and Griffiths 2015) is the most widely used questionnaire for assessing IGD. The present study examined support for the unidimensional factor structure of the instrument, with a group of 868 adolescent and adult gamers from the USA, with criteria recoded as present or absent. The two-parameter logistic model (2PLM) was used to examine the item response theory properties of the criteria included in the measure. Confirmatory factor analysis supported the one-factor model. The 2PLM analysis indicated that all the criteria were strong discriminators of high and low latent IGD. Furthermore, the items measured more of the GAD dimension and with more precision from around +2 SD from the mean trait level. The implications of the findings for interpreting the IGDS9-SF scores for clinical practice are discussed.

Anorexia nervosa and bulimia nervosa: A meta-analysis of executive functioning

Objective Research investigating the link between eating disorder (ED) diagnosis and executive dysfunction has had conflicting results, yet no meta‐analyses have examined the overall association of ED pathology with executive functioning (EF). Method Effect sizes were extracted from 32 studies comparing ED groups (27 of anorexia nervosa, 9 of bulimia nervosa) with controls to determine the grand mean effect on EF. Analyses included effects for individual EF measures, as well as an age‐based subgroup analysis. Results There was a medium effect of ED diagnosis on executive functioning, with bulimia nervosa demonstrating a larger effect (Hedges’s g = −0.70) than anorexia nervosa (g = −0.41). Within anorexia nervosa studies, subgroup analyses were conducted for age and diagnostic subtype. The effect of anorexia nervosa on EF was largest in adults; however, subgroup differences for age were not significant. Conclusions Anorexia and bulimia nervosa are associated with EF deficits, which are particularly notable for individuals with bulimia nervosa. The present analysis includes recommendations for future studies regarding study design and EF measurement. HighlightsIndividuals with anorexia nervosa show small to moderate impairments in executive functioning.Individuals with bulimia nervosa show moderate to large impairments in executive functioning.Both sets of studies demonstrated homogeneity in outcomes.Neither age nor diagnostic subtype subgroup analyses of anorexia nervosa were significant.

Proportion as a metric of problematic alcohol-energy drink consumption in college students

ABSTRACT Background: Alcohol mixed with energy drinks (AmED) is linked to deleterious drinking, particularly within college students. However, measurement and methodological concerns complicate a more thorough understanding of how AmED contributes to problematic alcohol consumption. This study examined AmED proportion (i.e., percentage of overall drinking events involving AmED consumption) as a metric for differentiating problematic alcohol use and tested the utility for explaining additional risk of alcohol-related problems beyond overall alcohol involvement. Methods: Self-report data were collected from a diverse sample of AmED consumers from two west-coast U.S. universities (N = 458; 60.1% female; 31.4% White). Participants were divided into three AmED proportion groups: low (25% or less of all drinking events), moderate (about 50%), or high (75% or more), and assessed for overall alcohol use and related consequences. Results: The groups did not differ on demographics or recent alcohol use. However, high proportion users reported significantly more alcohol-related problems than the low and moderate groups, even after controlling for overall alcohol involvement. However, proportion did not differentiate at-risk drinking as measured by cut-scores of the AUDIT. Conclusions: Findings provide support for proportion as metric for differentiating alcohol-related problems within AmED consumers. Implications for future research and interventions were discussed.

Measurement invariance: The case of measuring romantic attachment in Greek and Cypriot adolescents

Abstract The experiences in close relationships revised (ECR-R) is widely used to assess romantic attachment dimensions. Investigating cultural limitations in its applicability is imperative. This study aims to examine the instrument’s: (1) factor structure in two large and normative samples of Greek (N = 1706, M age = 16.16; SD = 2.16; 49.7% male) and Cypriot (N = 1279; M age = 15.54; SD = 0.65; 44.9% male) adolescents; (2) measurement invariance between these groups, accounting for potential gender and age effects. Results supported the two-factor structure and indicated partial invariance of the constructs between Greek and Cypriot adolescents. Findings support limitations in the use of instruments adapted for Greece in Cyprus.
