Background The Warwick Edinburgh Mental Well-Being Scale (WEMWBS) is a measure of subjective well-being and assesses eudemonic and hedonic aspects of well-being. However, differential scoring of the WEMWBS across gender and its precision of measurement has not been examined. The present study assesses the psychometric properties of the WEMWBS using measurement invariance (MI) between males and females and item response theory (IRT) analyses. Method A community sample of 386 adults from the United States of America (USA), United Kingdom, Ireland, Australia, New Zealand, and Canada were assessed online (N = 394, 54.8% men, 43.1% women, Mage = 27.48, SD = 5.57). Results MI analyses observed invariance across males and females at the configural level and metric level but non-invariance at the scalar level. The graded response model (GRM) conducted to observe item properties indicated that all items demonstrated, although variable, sufficient discrimination capacity. Conclusions Gender comparisons based on WEMWBS scores should be cautiously interpreted for specific items that demonstrate different scalar scales and similar scores indicate different severity. The items showed increased reliability for latent levels of ∓ 2 SD from the mean level of SWB. The WEMWBS may also not perform well for clinically low and high levels of SWB. Including assessments for clinical cases may optimise the use of the WEMWBS.
Background Disordered Internet gaming is thought to be perpetuated by one's need to escape their real‐life distress or mental health symptoms, which may in turn generate depressive feelings. Nevertheless, moderate engagement with Internet games has also been suggested to provide relief, thus improving one's mood. This study aspires to clarify the contribution of Internet gaming and gender in the association between anxiety and depression. Methods A large sample of Internet gamers (N = 964) were recruited online. Disordered Internet gaming was assessed with the Internet Gaming Disorder Scale, 9 Items Short Form (IGD9S‐SF). Anxiety and depression symptoms were assessed using the Depression, Anxiety and Stress Scale, 21 items (DASS‐21). Results Regression, moderation and moderated moderation analyses accounting for the effects of gender on the relationship between disordered gaming, anxiety, and depression found a significant effect for anxiety symptoms on depression symptoms and a significant interaction between anxiety and Internet gaming disorder on depression symptoms. Findings support the theory that although anxious gamers bear a higher depression risk, this is buffered with lower and exacerbated with higher disordered gaming symptoms. Conclusion Findings suggest a dual role of Internet gaming in the association between anxiety and depression, depending on the intensity of one's disordered gaming symptoms. Depression prevention and intervention protocols should be optimized by considering the effects of Internet gaming among anxious gamers by focusing on the intensity of a gamer's involvement and any gaming disorder symptoms. Further research should include clinical samples to better understand this interaction.
