The link between problematic internet use, problematic gaming, and psychological distress: does sleep quality matter?

Abstract Introduction This study aimed to examine the mediating role of sleep quality in the association of problematic internet use (PIU) and problematic gaming with psychological distress among college students in China. Methods Data of 1040 full-time students from multiple colleges in China were examined. Respondents were asked about their internet use and gaming behaviors, sleep quality, psychological distress, and sociodemographic characteristics. The mediating role of sleep quality in the PIU- and problematic gaming-psychological distress link was examined respectively. Results PIU was associated with decreased sleep quality (r = .32, p < .001) and increased psychological distress (r = .46, p < .001). Problematic gaming was also associated with decreased sleep quality (r = .22, p < .001) and increased psychological distress (r = .46, p < .001). Sleep quality accounted for 23.5% of the indirect effect of PIU on psychological distress, and 17.9% of the indirect effect of problematic gaming on psychological distress. Conclusions Sleep quality had a meaningful mediating effect on the PIU-psychological distress link, but only exerted a small mediating effect on the problematic gaming-psychological distress link. In addition to promoting healthy internet usage, strategies aimed at mitigating the negative effect of excessive internet use on psychological health might benefit from those aimed at improving sleep quality.

The aim of this study was to examine adolescent compulsive internet use (CIU) across a one-year period, to examine associations with symptoms of depression, anxiety and dissociation, as well as to analyze the potential mediating effect of dissociation symptoms. Previous studies have indicated that dissociation might serve as a coping strategy and/or as a consequence of problematic internet use. Participating in the study were 80 adolescents (39 girls and 41 boys), ages from 12 to 18 (mean age 14.90 years) at the time of the first measurement. At Time 1 and one year later at Time 2 measurement points the participants completed the Trauma Symptom Checklist (Briere, 1995) and items from the Compulsive Internet Use Scale (Meerkert, VanDen Eijnden, Vermulst, & Garretsen, 2009). Correlation analyses showed associations between CIU and the adolescents’ ratings of anxiety, depression and dissociation at Time 1 and Time 2. Mediation analysis indicated partial mediation of dissociation symptoms between CIU at Time 1 and Time 2. A comparison of these relationships across time provides opportunity to discuss possible directions of causality and implications of bidirectionality between dissociative tendencies and adolescent prolonged, compulsive internet use.

The Impact

Purpose – The purpose of this paper is to analyze the impact of individual logistics-related factors, namely, supplier involvement (SI), length of supplier relationship (LSR), use of information technology (IT), and logistics integration (LI) on a firm's supply chain performance (SCP) and test for the mediating effect of LI in a multi-country survey conducted in Brazil, Korea and India. The paper also develops a composite variable, supply chain competency (SCC), as an overall measure of the quality of a firm's supply chain and demonstrate its effect on a firm's SCP. Design/methodology/approach – The research methodology was based on designing and administering a survey instrument. Data collected from 187 organizations in Brazil, Korea and India were analyzed using the partial least squares structural equation modeling methodology. Findings – Results show that for the combined data, the direct effects of SI, LSR and IT on SCP are insignificant while LI has a very significant direct effect on SCP. On the other hand, except for SI, LSR and IT have significant effects on SCP through LI establishing the mediating role of LI. The paper also finds that SCC has a significant effect on SCP. Further, when countries are considered individually the paper finds that IT has a significant indirect effect on SCP in the case of all the countries while LSR has a significant indirect effect on SCP, both in the case of Brazil and Korea. Additionally, in the case of Korea SI has a significant indirect effect on SCP. Research limitations/implications – Like other survey-based research, the findings of this paper are also limited by the sample size. Especially, the observations specific to individual countries are as good as the respective sample sizes. Also, since all the respondents belonged to manufacturing firms, the findings of this paper are relevant for the manufacturing sector. Practical implications – This paper establishes the mediating effect of LI in assessing the impact of logistics-related factors on a firm's SCP. It confirms that although logistics-related factors are necessary for a firm's superior SCP, they are not sufficient unless their interactions are taken into consideration, as evidenced by the significant positive relationship between SCC and SCP. Originality/value – To the best of the authors’ knowledge, this paper is the first paper to study the effect of logistics-related factors on a firm's SCP and establish the mediating role of LI in a multi-country setting. This paper also develops a composite variable SCC and examines its effect on SCP.
