| Outline of Research at the Start |
Gaming disorder is now classified as a mental disorder. The literature suggests that poor emotion regulation skills not only predict pathological gaming behavior but also lead to emotional disorders such as depression and anxiety. As emotional difficulties appear to be both risk factors and consequences of gaming disorder, this study will further identify mechanisms and effective ways to reduce emotional problems related to gaming disorder. This study will aim to understand about how emotional difficulties play a role in problematic gaming behavior.

| Outline of Annual Research Achievements |
This year, the investigator undertook the project as follows.
<Study 1: A cross-sectional association of gaming disorder with internalizing and family factors in children and youths> The investigator finished analyzing collected data and posted the first draft of the manuscript as a preprint（Hamamura et al., 2024, PsyArXiv). Despite the significant association between child-reported gaming disorder and internalizing symptoms, β = .023, p = .03, the latent association measuring the cross-informant agreement was not significant, β = .004, p = .86. The only significant moderator was the parent-reported positive parenting behavior in the latent association between gaming disorder and internalizing symptoms, β = .004, p = .04. At the dyadic-level, gaming disorder and internet gaming disorder had the same pattern of associations with the other measures. In contrast, a different pattern emerged at the person-level. This multi-informant measurement may indicate a possible inflation of the self-reported positive association between gaming disorder and internalizing symptoms.
<Study 2: A longitudinal association between gaming disorder and internalizing in youths> The investigator completed the follow-up data collection.
<Study 3: A Japanese version of the Motivation for Online Gaming Questionnaire (MOGQ)> The investigator conducted a validation study for the translated scale and presented the findings at an international conference. The factor structure of the Japanese version of the MOGQ differed from that of the original scale.

4: Progress in research has been delayed.
Reason
The investigator moved overseas to undertake another research project. The progress of this project was consequently delayed.
|
| Strategy for Future Research Activity |
The investigator applied for a one-year extension. In the next fiscal year, the investigator plans to analyze data for Study 2 and present findings.
