Background: While there are calls to restrict the time spent on gaming because it is seen as problematic and potentially leading to gaming disorder (GD), there is conflicting evidence about this issue. We explored the association between the average weekly time spent gaming and reported GD symptoms. Additionally, Latent Profile Analysis was employed to investigate how time spent gaming relates to variables representing psychological distress (PD), such as satisfaction with life, symptoms of depression, and perceived stress.

Methods: Data were collected using surveys with a large sample of highly engaged gamers (N = 14,740; Mage = 24.14 years, SDage = 7.0, 89.3% males).

Results: We observed a positive, close to linear association between time spent gaming and GD symptoms. Groups at risk of GD played for about 42 h (SD = 19) on average, according to the American Psychiatric Association and World Health Organization frameworks. Furthermore, we identified four profiles representing varying levels of PD. Gamers reporting very high levels of PD (4.2% of the sample) played for 33 h per week on average. Remarkably, a substantial percentage of the sample (41.9%) showed no PD despite playing for 26 h per week.

Conclusion: The association between gaming time and PD is complex as even prolonged time spent gaming can be unproblematic for many gamers.

背景:虽然有人呼吁限制游戏时间,因为游戏被认为是有问题的,有可能导致游戏障碍(GD),但有关这一问题的证据却相互矛盾。我们探讨了每周平均游戏时间与所报告的游戏障碍症状之间的关联。此外,我们还采用了潜在特征分析法来研究游戏时间与代表心理困扰(PD)的变量(如生活满意度、抑郁症状和感知压力)之间的关系:结果:我们观察到正向的、接近线性关系的游戏时间与心理压力之间的关系:我们发现,游戏时间与广东话症状之间存在接近线性的正相关。根据美国精神病学协会和世界卫生组织的框架,GD高危人群的平均游戏时间约为42小时(SD=19)。此外,我们还发现了四种代表不同程度 PD 的特征。PD程度很高的游戏者(占样本的 4.2%)平均每周游戏 33 小时。值得注意的是,有相当比例的样本(41.9%)尽管每周游戏时间为 26 小时,却没有显示出肢体麻木症:游戏时间与帕金森病之间的关系非常复杂,因为即使长时间玩游戏,对许多游戏玩家来说也可能没有任何问题。

Background and aims: Despite the inclusion of the Compulsive Sexual Behavior Disorder (CSBD) in the 11th edition of the International Classification of Diseases, emotional and cognitive impairments related to CSBD remains unclear. This study aimed to investigate the behavioral and neuronal effects of emotional interference on cognition among CSBD patients.

Methods: Thirty heterosexual males with CSBD and matched healthy controls (HC) were studied with the Emotional Stroop Task using 5 categories of emotionally arousing words (sex-related, positive, fear-related, negative, neutral) during functional magnetic imaging.

Results: At the behavioral level, we found the main effect of the condition: sex-related words evoked a stronger Stroop effect than other conditions. At the neural level, we found a significant group effect. Among CSBD patients processing of sex-related words was related to increased activity in the right putamen, right thalamus, hippocampi, and left pulvinar, when compared to HC. We also found a negative correlation between neuronal activation and time spent on sexual activity during the week preceding study and numerous group differences in brain regions connected to the emotional and motivational processing of sexually explicit material, correlating with CSBD symptoms.

Conclusions: Behavioral results indicate a specific attentional bias toward sex-related stimuli in both groups, while neural data uncovered stronger reactivity to sex-related words in CSBD compared to HC. This reactivity is related to CSBD symptoms and provides evidence for the interference of sex-related stimuli with cognition. Such results are firmly in line with the Incentive Salience Theory and conceptualizing CSBD as a behavioral addiction.

背景和目的:尽管强迫性性行为障碍(CSBD)已被列入第11版《国际疾病分类》,但与CSBD相关的情感和认知障碍仍不明确。本研究旨在调查情绪干扰对 CSBD 患者认知的行为和神经元影响:在功能磁成像过程中,对30名患有CSBD的异性恋男性和匹配的健康对照组(HC)进行了情绪Stroop任务研究,使用了5类情绪唤醒词(性相关、积极、恐惧相关、消极、中性):结果:在行为层面,我们发现了条件的主效应:与性相关的词语比其他条件下的词语更能引起强烈的 Stroop 效应。在神经层面,我们发现了显著的群体效应。与 HC 相比,CSBD 患者在处理与性有关的词语时,右侧丘脑、右侧丘脑、海马和左侧脉管的活动增加。我们还发现,神经元激活与研究前一周花在性活动上的时间呈负相关,而且与性暴露材料的情感和动机处理有关的脑区存在许多群体差异,这与 CSBD 症状相关:行为结果表明,两组人对与性有关的刺激都有特定的注意偏向,而神经数据则揭示了与 HC 相比,CSBD 对与性有关的词语更强的反应性。这种反应性与 CSBD 症状有关,为与性有关的刺激对认知的干扰提供了证据。这些结果与 "刺激显著性理论"(Incentive Salience Theory)以及将 CSBD 概念化为一种行为成瘾是完全一致的。

Background: Changes in brain structural connections appear to be important in the pathophysiology of substance use disorders, but their role in behavioral addictions, such as gambling disorder (GD), is unclear. GD also offers a model to study addiction mechanisms without pharmacological confounding factors. Here, we used multimodal MRI data to examine the integrity of white matter connections in individuals with GD. We hypothesized that the affected areas would be in the fronto-striatal-thalamic circuit.

Methods: Twenty individuals with GD (mean age: 64 years, GD duration: 15.7 years) and 40 age- and sex-matched healthy controls (HCs) underwent detailed clinical examinations together with brain 3T MRI scans (T1, T2, FLAIR and DWI). White matter (WM) analysis involved fractional anisotropy and lesion load, while gray matter (GM) analysis included voxel- and surface-based morphometry. These measures were compared between groups, and correlations with GD-related behavioral characteristics were examined.

Results: Individuals with GD showed reduced WM integrity in the left and right frontal parts of the corona radiata and corpus callosum (pFWE < 0.05). WM gambling symptom severity (SOGS score) was negatively associated to WM integrity in these areas within the left hemisphere (p < 0.05). Individuals with GD also exhibited higher WM lesion load in the left anterior corona radiata (pFWE < 0.05). GM volume in the left thalamus and GM thickness in the left orbitofrontal cortex were reduced in the GD group (pFWE < 0.05).

Conclusions: Similar to substance addictions, the fronto-striatal-thalamic circuit is also affected in GD, suggesting that this circuitry may have a crucial role in addictions, independent of pharmacological substances.

背景:大脑结构连接的变化在药物使用障碍的病理生理学中似乎很重要,但它们在行为成瘾(如赌博障碍)中的作用还不清楚。赌博障碍也为研究成瘾机制提供了一个没有药理混杂因素的模型。在这里,我们使用多模态核磁共振成像数据研究了 GD 患者白质连接的完整性。我们假设受影响的区域位于前额纹状体-丘脑回路:20 名 GD 患者(平均年龄:64 岁,GD 病程:15.7 年)和 40 名年龄和性别匹配的健康对照组(HCs)接受了详细的临床检查和脑 3T MRI 扫描(T1、T2、FLAIR 和 DWI)。白质(WM)分析包括分数各向异性和病变负荷,而灰质(GM)分析包括基于体素和表面的形态测量。这些测量结果在各组之间进行了比较,并考察了与广东话相关的行为特征的相关性:结果发现:GD患者放射冠和胼胝体的左右额叶部分的WM完整性降低(pFWE < 0.05)。WM赌博症状严重程度(SOGS评分)与左半球这些区域的WM完整性呈负相关(p<0.05)。GD患者的左侧放射冠前部也表现出较高的WM病变负荷(pFWE < 0.05)。GD组患者左侧丘脑的GM体积和左侧眶额皮层的GM厚度均有所减少(pFWE < 0.05):结论:与药物成瘾类似,前额叶-纹状体-丘脑回路在 GD 中也受到影响,这表明该回路可能在成瘾中起着关键作用,与药物无关。

Co-occurring compulsive sexual behaviour in an inpatient substance use population: Clinical correlates and influence on treatment outcomes. 住院病人中的强迫性性行为:临床相关性及对治疗结果的影响。
IF 6.6 1区 医学 Q1 PSYCHIATRY Pub Date : 2024-06-21 Print Date: 2024-06-26 DOI: 10.1556/2006.2024.00035

Background and aims: Many individuals with substance use disorders (SUDs) present with co-occurring mental health disorders and other addictions, including behavioral addictions (BAs). Though several studies have investigated the relationship between SUDs and BAs, less research has focused specifically on compulsive sexual behaviour (CSB). Given that poly-addiction can hinder treatment outcomes, it is necessary to better understand the impact of co-occurring CSB and SUD. Therefore, the current study aimed to 1) determine the rate of CSB in a sample seeking treatment for SUDs, 2) identify demographic and clinical correlates of co-occurring CSB, and 3) to determine if co-occurring CSB impacts treatment outcomes for SUD.

Methods: Participants were 793 adults (71.1% men) ranging in age from 18-77 (M = 38.73) at an inpatient treatment facility for SUDs who were assessed for CSB upon admission into treatment. Participants completed a battery of questionnaires upon admission and at discharge to assess psychological and addiction symptoms.

Results: Rates of CSB were 24%. Younger age and being single were associated with greater CSB. Mental distress and addiction symptoms were higher in participants with CSB. Predictors of CSB severity included greater symptoms of traumatic stress and interpersonal dysfunction. Rates of treatment completion were similar between participants with and without CSB.

Discussion and conclusions: These results highlight several clinical and demographic correlates of CSB amongst individuals in treatment for SUD. However, CSB was not associated with poorer treatment outcomes. Further identifying characteristics associated with CSB can help clinicians identify individuals who may be at higher risk.

背景和目的:许多药物使用障碍(SUD)患者同时伴有精神疾病和其他成瘾,包括行为成瘾(BA)。虽然已有多项研究调查了药物使用障碍与行为成瘾之间的关系,但专门针对强迫性行为(CSB)的研究较少。鉴于多重成瘾会阻碍治疗效果,因此有必要更好地了解 CSB 和 SUD 共存的影响。因此,本研究旨在:1)确定寻求 SUD 治疗的样本中 CSB 的比例;2)确定共存 CSB 的人口统计学和临床相关性;3)确定共存 CSB 是否会影响 SUD 的治疗效果:参与者为 793 名成年人(71.1% 为男性),年龄在 18-77 岁之间(M=38.73),他们曾在一家 SUD 住院治疗机构接受治疗,并在入院时接受了 CSB 评估。参与者在入院和出院时填写了一系列问卷,以评估心理和成瘾症状:CSB率为24%。年龄较小和单身与CSB较高有关。有 CSB 的参与者的精神痛苦和成瘾症状更严重。CSB严重程度的预测因素包括更严重的创伤应激症状和人际交往障碍。有 CSB 和没有 CSB 的参与者完成治疗的比率相似:这些结果突显了接受药物滥用治疗者中 CSB 的一些临床和人口学相关因素。然而,CSB 与较差的治疗效果无关。进一步确定与CSB相关的特征有助于临床医生识别可能面临较高风险的个体。

Objective: The present study aimed to evaluate the efficacy of a mindfulness-based cognitive therapy (MBCT) intervention in reducing problematic mobile phone use, depression, and sleep disorders among adolescents. Additionally, it sought to investigate whether the decrease in problematic mobile phone use acted as a mediator in the relationship between the MBCT intervention and adolescent depression and sleep disorders.

Methods: In a randomized controlled trial, a total of 104 adolescents were randomly assigned to the mindfulness group (n = 52) or the wait-list control group (n = 52). The mindfulness group students completed eight 45-min sessions of mindfulness training in four weeks. The outcomes were measured at baseline, postintervention, and at the 2-month follow-up.

Results: Compared with the control group, the mindfulness group had significantly greater levels of mindfulness and lower levels of problematic mobile phone use, depression, and sleep disorders postintervention. The intervention effects were maintained at the 2-month follow-up. In addition, decreased problematic mobile phone use significantly mediated the association between the MBCT intervention and decreased depression and decreased sleep disorders.

Conclusion: The findings suggest that MBCT could improve adolescent depression and sleep disorders and that decreasing problematic mobile phone use is an effective pathway accounting for the MBCT intervention effect on adolescent depression and sleep disorders.

研究目的本研究旨在评估正念认知疗法(MBCT)干预在减少青少年问题性手机使用、抑郁和睡眠障碍方面的疗效。此外,本研究还试图调查问题手机使用量的减少是否会成为 MBCT 干预与青少年抑郁和睡眠障碍之间关系的中介因素:在随机对照试验中,共有 104 名青少年被随机分配到正念组(52 人)或等待对照组(52 人)。正念组学生在四周内完成八节45分钟的正念训练课。结果在基线、干预后和两个月的随访中进行了测量:结果:与对照组相比,正念组学生的正念水平明显提高,干预后的手机使用问题、抑郁和睡眠障碍水平明显降低。干预效果在两个月的随访中得以保持。此外,手机使用问题的减少在很大程度上调节了MBCT干预与抑郁和睡眠障碍减少之间的关系:研究结果表明,MBCT 可改善青少年抑郁和睡眠障碍,而减少使用问题手机是 MBCT 干预对青少年抑郁和睡眠障碍产生影响的有效途径。

Background and aims: The association between perceived stress (PS) and gaming addiction (GA) is well documented. However, the mechanism for explaining this association remains unclear. Using a genetically informative design, this study aims to distinguish between the diathesis-stress and bio-ecological models of gene by environment interaction (G x E) to explain the underlying mechanism of the relationship.

Methods: In total, 1,468 twins (mean age = 22.6 ± 2.8 years) completed an online survey including the GA and PS scales. Twin correlations for GA and PS were computed and univariate model-fitting analysis was conducted to determine genetic and environmental influences on GA and PS. The bivariate G x E model-fitting analysis was performed to determine the best G x E interaction model.

Results: Additive genetic, shared environmental, and non-shared environmental effects were 0.70 (95%CI = 0.61, 0.77), 0.00, and 0.30 (95%CI = 0.26, 0.33), and 0.38 (95%CI = 0.24, 0.55), 0.35 (95% CI = 0.18, 0.51), and 0.22 (95%CI = 0.20, 0.26) for GA and PS, respectively. Bivariate G x E model-fitting analysis supported the diathesis-stress model, where genetic influences on GA were greater in higher levels of PS, whereas environmental influences on GA were small and constant across levels of PS.

Discussion and conclusions: The evidence for the diathesis-stress model for GA is consistent with the etiological process of many forms of psychopathology. The findings should be incorporated in clinical settings to improve the treatment of GA, and used in developments of intervention and prevention methods for GA.

背景和目的:感知到的压力(PS)与游戏成瘾(GA)之间的关联已被充分证实。然而,解释这种关联的机制仍不清楚。本研究采用基因信息设计,旨在区分基因与环境交互作用(G x E)的病因-压力模型和生物-生态模型,以解释这种关系的内在机制:共有 1,468 对双胞胎(平均年龄 = 22.6 ± 2.8 岁)完成了包括 GA 和 PS 量表在内的在线调查。计算了GA和PS的双胞胎相关性,并进行了单变量模型拟合分析,以确定遗传和环境对GA和PS的影响。对GA x E进行双变量模型拟合分析,以确定最佳的G x E交互模型:GA和PS的加性遗传效应、共有环境效应和非共有环境效应分别为0.70(95%CI = 0.61,0.77)、0.00和0.30(95%CI = 0.26,0.33),以及0.38(95%CI = 0.24,0.55)、0.35(95%CI = 0.18,0.51)和0.22(95%CI = 0.20,0.26)。双变量 G x E 模型拟合分析支持二合成-压力模型,即在 PS 水平较高时,遗传对 GA 的影响较大,而环境对 GA 的影响较小,且在不同 PS 水平下保持不变:GA的病因-压力模型的证据与多种形式精神病理学的病因过程是一致的。这些发现应纳入临床环境,以改善 GA 的治疗,并用于开发 GA 的干预和预防方法。

Background and aims: Subjective confidence plays an important role in guiding behaviour, especially when objective feedback is unavailable. Systematic misjudgements in confidence can foster maladaptive behaviours and have been linked to various psychiatric disorders. In this study, we adopted a transdiagnostic approach to examine confidence biases in problem gamblers across three levels: local decision confidence, global task performance confidence, and overall self-esteem. The importance of taking a transdiagnostic perspective is increasingly recognised, as it captures the dimensional nature of psychiatric symptoms that often cut across diagnostic boundaries. Accordingly, we investigated if any observed confidence biases could be explained by transdiagnostic symptom dimensions of Anxiety-Depression and Compulsive Behaviour and Intrusive Thought. This approach allows us to gain a more comprehensive understanding of the role of metacognitive processes in problem gambling, beyond the constraints of traditional diagnostic categories.

Methods: Thirty-eight problem gamblers and 38 demographically matched control participants engaged in a gamified metacognition task and completed self-report questionnaires assessing transdiagnostic symptom dimensions.

Results: Compared to controls, problem gamblers displayed significantly elevated confidence at the local decision and global task levels, independent of their actual task performance. This elevated confidence was observed even after controlling for the heightened symptom levels of Anxiety-Depression and Compulsive Behaviour and Intrusive Thought among the problem gamblers.

Discussion: The results reveal a notable disparity in confidence levels between problem gamblers and control participants, not fully accounted for by the symptom dimensions Anxiety-Depression and Compulsive Behaviour and Intrusive Thought. This suggests the contribution of other factors, perhaps linked to gambling-specific cognitive distortions, to the observed confidence biases.

Conclusion: The findings highlight the intricate link between metacognitive confidence and psychiatric symptoms in the context of problem gambling. It underscores the need for further research into metacognitive biases, which could enhance therapeutic approaches for individuals with psychiatric conditions.

背景和目的:主观信心在指导行为方面发挥着重要作用,尤其是在无法获得客观反馈的情况下。系统性的信心误判会助长不适应行为,并与各种精神疾病有关。在本研究中,我们采用了一种跨诊断方法,从三个层面来研究问题赌徒的自信偏差:局部决策自信、整体任务绩效自信和整体自尊。跨诊断视角的重要性日益得到认可,因为它能捕捉到精神症状的多维性,而这些症状往往跨越诊断界限。因此,我们研究了所观察到的自信偏差是否可以用焦虑-抑郁和强迫行为及侵入性思维等跨诊断症状维度来解释。这种方法使我们能够超越传统诊断类别的限制,更全面地了解元认知过程在问题赌博中的作用:方法:38 名问题赌博者和 38 名人口统计学上匹配的对照组参与者参与了游戏化元认知任务,并完成了评估跨诊断症状维度的自我报告问卷:与对照组相比,问题赌徒在局部决策和全局任务层面上的自信心明显增强,这与他们的实际任务表现无关。即使在控制了问题赌徒的焦虑抑郁、强迫行为和侵入性思维等症状水平后,也能观察到这种自信心的提升:讨论:研究结果表明,问题赌徒与对照组参与者在自信水平上存在明显差异,而焦虑抑郁、强迫行为和侵入性思维等症状并不能完全解释这种差异。这表明,其他因素(可能与赌博特有的认知扭曲有关)也会导致观察到的自信偏差:研究结果凸显了问题赌博中元认知自信与精神症状之间错综复杂的联系。结论:研究结果凸显了问题赌博中元认知信心与精神症状之间错综复杂的联系,强调了进一步研究元认知偏差的必要性,这将有助于加强对精神疾病患者的治疗方法。

Brain alterations in individuals with exercise dependence: A multimodal neuroimaging investigation. 运动依赖症患者的大脑变化:多模态神经影像学调查。
IF 6.6 1区 医学 Q1 PSYCHIATRY Pub Date : 2024-06-05 Print Date: 2024-06-26 DOI: 10.1556/2006.2024.00028

Background: Exercise dependence (ED) is characterised by behavioural and psychological symptoms that resemble those of substance use disorders. However, it remains inconclusive whether ED is accompanied by similar brain alterations as seen in substance use disorders. Therefore, we investigated brain alterations in individuals with ED and inactive control participants.

Methods: In this cross-sectional neuroimaging investigation, 29 individuals with ED as assessed with the Exercise Dependence Scale (EDS) and 28 inactive control participants (max one hour exercising per week) underwent structural and functional resting-state magnetic resonance imaging (MRI). Group differences were explored using voxel-based morphometry and functional connectivity analyses. Analyses were restricted to the striatum, amygdala, and inferior frontal gyrus (IFG). Exploratory analyses tested whether relationships between brain structure and function were differently related to EDS subscales among groups.

Results: No structural differences were found between the two groups. However, right IFG and bilateral putamen volumes were differently related to the EDS subscales "time" and "tolerance", respectively, between the two groups. Resting-state functional connectivity was increased from right IFG to right superior parietal lobule in individuals with ED compared to inactive control participants. Furthermore, functional connectivity of the angular gyrus to the left IFG and bilateral caudate showed divergent relationships to the EDS subscale "tolerance" among groups.

Discussion: The findings suggest that ED may be accompanied by alterations in cognition-related brain structures, but also functional changes that may drive compulsive habitual behaviour. Further prospective studies are needed to disentangle beneficial and detrimental brain effects of ED.

背景:运动依赖(ED)的特征是行为和心理症状与药物使用障碍相似。然而,运动依赖是否伴有与药物使用障碍相似的脑部改变,目前仍无定论。因此,我们研究了ED患者和非活动对照参与者的大脑变化:在这项横断面神经影像学调查中,29 名通过运动依赖量表(EDS)评估的 ED 患者和 28 名非运动型对照组参与者(每周最多运动一小时)接受了结构性和功能性静息态磁共振成像(MRI)检查。研究人员使用基于体素的形态计量学和功能连通性分析探讨了组间差异。分析仅限于纹状体、杏仁核和额叶下回(IFG)。探索性分析测试了大脑结构和功能之间的关系是否与各组的 EDS 分量表有不同的关系:结果:两组之间未发现结构差异。然而,两组间右侧 IFG 和双侧 Putamen 的体积分别与 EDS 分量表 "时间 "和 "耐受性 "的关系不同。与非活动对照组相比,ED患者从右侧IFG到右侧上顶叶的静息状态功能连接性增强。此外,角回与左侧IFG和双侧尾状体的功能连接与EDS分量表 "耐受性 "的关系在不同组间存在差异:讨论:研究结果表明,ED可能伴随着与认知相关的大脑结构的改变,但也可能伴随着驱动强迫性习惯行为的功能变化。需要进一步开展前瞻性研究,以区分 ED 对大脑的有益和有害影响。

Moderating effects of PER3 gene DNA methylation on the association between problematic mobile phone use and chronotype among Chinese young adults: Focus on gender differences. PER3基因DNA甲基化对中国青少年使用问题手机与慢性型之间关系的调节作用:关注性别差异
IF 6.6 1区 医学 Q1 PSYCHIATRY Pub Date : 2024-06-03 Print Date: 2024-06-26 DOI: 10.1556/2006.2024.00027

Objective: To investigate the rates of problematic mobile phone use (PMPU) and chronotypes in young adults, and examine the associations of PMPU with chronotypes, as well as its gender differences. Furthermore, we explored the moderating role of PER3 gene DNA methylation on the associations.

Methods: From April to May 2019, a total of 1,179 young adults were selected from 2 universities in Anhui and Jiangxi provinces. The Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use (SQAPMPU) and reduced Morningness-Eveningness Questionnaire (rMEQ) were adopted to investigate PMPU and chronotypes in young adults, respectively. Moreover, 744 blood samples were collected to measure PER3 gene DNA methylation. Multivariate logistic regression models were established to analyze the associations between PMPU and chronotypes. Moderating analysis was used to determine whether PER3 gene DNA methylation moderated the relationships between PMPU and chronotypes.

Results: The prevalence of PMPU, morning chronotypes (M-types), neutral chronotypes (N-types), and evening chronotypes (E-types) of young adults were 24.6%, 18.4%, 71.1%, and 10.5%, respectively. Multivariate logistic regression results indicated that PMPU was positively correlated with E-types (OR = 3.53, 95%CI: 2.08-6.00), and the association was observed only in females after stratified by gender (OR = 5.36, 95%CI: 2.70-10.67). Furthermore, PER3 gene DNA methylation has a negative moderating role between PMPU and chronotypes and has a sex-based difference.

Conclusions: This study can provide valuable information for the prevention and control of circadian rhythm disturbance among young adults from the perspective of epidemiology and biological etiology.

目的调查青壮年中问题手机使用率(PMPU)和时间型,研究PMPU与时间型的关联及其性别差异。此外,我们还探讨了PER3基因DNA甲基化对两者关联的调节作用:2019年4月至5月,我们从安徽和江西两省的2所高校共选取了1179名青壮年。采用青少年问题性手机使用自评量表(SQAPMPU)和还原型晨醒-活力问卷(rMEQ)分别调查青壮年的PMPU和时型。此外,研究人员还采集了 744 份血液样本,以测定 PER3 基因的 DNA 甲基化情况。研究人员建立了多变量逻辑回归模型来分析 PMPU 与时间型之间的关系。调节分析用于确定 PER3 基因 DNA 甲基化是否调节了 PMPU 与时型之间的关系:结果:PMPU、早晨时型(M 型)、中性时型(N 型)和傍晚时型(E 型)在年轻人中的流行率分别为 24.6%、18.4%、71.1% 和 10.5%。多变量逻辑回归结果表明,PMPU 与 E 型呈正相关(OR = 3.53,95%CI:2.08-6.00),按性别分层后,仅在女性中观察到这种关联(OR = 5.36,95%CI:2.70-10.67)。此外,PER3基因的DNA甲基化在PMPU和时间型之间具有负向调节作用,且存在性别差异:本研究可从流行病学和生物病因学的角度为预防和控制青壮年昼夜节律紊乱提供有价值的信息。

Background and objectives: As the gaming industry experiences exponential growth, concerns about gaming disorder (GD) also grow. It is crucial to understand the structural features of games that can interact with individual characteristics of gamers to promote GD. This research consolidates the views of an international body of panelists to create an assessment tool for gauging the addictive potential of distinct games.

Methods: Utilizing the iterative and structured Delphi method, an international panel of researchers, clinicians, and people with lived experience were recruited to offer a multifaceted viewpoint on the addictive risk associated with specific structural elements in games. Two rounds of surveys facilitated consensus.

Results: The panel initially included 40 members-ten from research, eight from clinical settings, and 22 with lived experiences. The second round included 27 panelists-seven from research, eight from clinical settings, and 11 with lived experiences. The study identified 25 structural features that contribute to potentially addictive gaming patterns.

Discussion and conclusions: Consensus was found for 25 features, which were distilled into a 23-item evaluation tool. The Saini-Hodgins Addiction Risk Potential of Games Scale (SHARP-G) consists of five overarching categories: 'Social,' 'Gambling-Like Features,' 'Personal Investment,' 'Accessibility,' and 'World Design.' SHARP-G yields a total score indicating level of addiction risk. A case study applying the scale to three games of differing perceived risk levels demonstrated that that score corresponded to game risk as expected. While the SHARP-G scale requires further validation, it provides significant promise for evaluating gaming experiences and products.

背景和目标:随着游戏产业的迅猛发展,人们对游戏障碍(GD)的担忧也与日俱增。了解游戏的结构特征会与游戏玩家的个人特征相互作用,从而诱发游戏障碍,这一点至关重要。本研究综合了国际专家小组成员的意见,创建了一种评估工具,用于衡量不同游戏的成瘾潜力:方法:利用迭代和结构化德尔菲法,招募了一个由研究人员、临床医生和有生活经验者组成的国际小组,就游戏中特定结构元素的成瘾风险提供多方面的观点。两轮调查促成了共识:小组最初包括 40 名成员--10 名来自研究机构,8 名来自临床机构,22 名具有生活经验。第二轮调查包括 27 名小组成员--其中 7 人来自研究机构,8 人来自临床机构,11 人有亲身经历。研究确定了 25 个导致潜在成瘾性游戏模式的结构特征:讨论与结论:25 项特征已达成共识,并被提炼为 23 项评估工具。塞尼-霍金斯游戏成瘾风险潜力量表(SHARP-G)包括五个主要类别:"社交"、"类似赌博的特征"、"个人投资"、"可访问性 "和 "世界设计"。SHARP-G 得出的总分表示成瘾风险水平。一项案例研究将该量表应用于三款风险程度不同的游戏,结果表明该分数与游戏风险的对应关系符合预期。虽然 SHARP-G 量表还需要进一步验证,但它为评估游戏体验和产品提供了巨大的前景。
