Since the inclusion of Compulsive Sexual Behavior Disorder (CSBD) in the International Classification of Diseases (11th ed.), there has been little effort placed into developing clinical recommendations for lesbian, gay, bisexual, and queer (LGBQ) clients with this condition. Thus, we develop preliminary clinical recommendations for mental health professionals working with LGBQ clients who may be struggling with CSBD.
自从强迫性性行为障碍(CSBD)被列入《国际疾病分类》(第 11 版)以来,针对患有这种疾病的女同性恋、男同性恋、双性恋和同性恋者(LGBQ)客户的临床建议鲜有出台。因此,我们为心理健康专业人员制定了初步的临床建议,以帮助那些可能患有 CSBD 的 LGBQ 患者。

Compulsive sexual behaviour in Iranian married women: Prevalence, sociodemographic, sexual, and psychological predictors across-country. 伊朗已婚妇女的强迫性行为:伊朗已婚妇女的强迫性行为:不同国家的流行率、社会人口、性和心理预测因素。
IF 6.6 1区 医学 Q1 PSYCHIATRY Pub Date : 2024-03-29 Print Date: 2024-06-26 DOI: 10.1556/2006.2024.00009

Background and aims: This study addresses the scarcity of research on Compulsive Sexual Behavior Disorder (CSBD) in non-Western cultures and women, exploring its prevalence, sociodemographic, sexual history characteristics, and sexual and psychological health factors in Iranian married women.

Methods: A cross-sectional study involving 772 heterosexual married women was conducted between 2022 and 2023, covering all 31 provinces of Iran. Participants were categorized as CSBD+ (at-risk individuals) and CSBD- (low-risk individuals) based on a pre-established cut-off point of ≥18 by the Compulsive Sexual Behavior Disorder Scale -7. Depression, anxiety, obsessive-compulsive disorder, self-esteem, sexual distress, sexual satisfaction, relationship satisfaction, and sexual dysfunction were assessed as psychological and sexual health variables by standardized scales.

Results: The prevalence of CSBD was 3.8% in women. Linear regression analysis showed that lower education, being jobless, substance use, pornography use, paraphilic behaviors, conflict on sex frequency, relationship, orgasm and sexual dissatisfaction, higher sexual arousal, depression, and obsessive-compulsive symptoms were positively associated with CSBD. The univariate analysis, at a stringent significance level of 0.005, mirrored the regression findings. Additionally, women with CSBD+ exhibited lower religiousness and higher anxiety compared to those without CSBD-.

Discussion and conclusions: Raising awareness of CSBD is crucial for health systems and individuals for better policy-making and help-seeking behavior. Identifying risk factors like substance use presents opportunities for prevention, and the association of CSBD with sexual and mental health variables suggests addressing co-occurring issues for improved treatment outcomes. Recognizing culture and gender-specific sexual and psychological correlates enables targeted and effective treatment approaches.

背景和目的:本研究针对非西方文化和女性中强迫性性行为障碍(CSBD)研究的稀缺性,探讨伊朗已婚女性中强迫性性行为障碍的患病率、社会人口学、性史特征以及性和心理健康因素:在 2022 年至 2023 年期间进行了一项横断面研究,涉及 772 名已婚异性恋妇女,覆盖伊朗所有 31 个省。根据强迫性行为障碍量表 -7 预先确定的≥18 分界点,将参与者分为 CSBD+(高危人群)和 CSBD-(低危人群)。抑郁、焦虑、强迫症、自尊、性困扰、性满意度、人际关系满意度和性功能障碍作为心理和性健康变量通过标准化量表进行评估:结果:女性 CSBD 患病率为 3.8%。线性回归分析表明,教育程度较低、无业、使用药物、使用色情制品、副性行为、性频率冲突、性关系、性高潮和性不满意、性兴奋较高、抑郁和强迫症状与 CSBD 呈正相关。在 0.005 的严格显著性水平下进行的单变量分析反映了回归结果。此外,与没有 CSBD 的女性相比,患有 CSBD+ 的女性表现出较低的宗教信仰和较高的焦虑:提高对 CSBD 的认识对于卫生系统和个人改善政策制定和求助行为至关重要。识别药物使用等风险因素为预防提供了机会,而 CSBD 与性健康和心理健康变量的关联表明,要改善治疗效果,就必须解决同时存在的问题。认识到文化和性别特有的性和心理相关性,就能采取有针对性的有效治疗方法。

Definitions and assessments of recovery from gambling disorder: A scoping review. 赌博障碍康复的定义和评估:范围审查。
IF 6.6 1区 医学 Q1 PSYCHIATRY Pub Date : 2024-03-29 Print Date: 2024-06-26 DOI: 10.1556/2006.2024.00008

Background and aims: While the concept of recovery is receiving increasing attention in the context of gambling disorder (GD), no consensus has yet been reached regarding its definition. This scoping review aims to map the literature on GD recovery, identify gaps, and provide insights for a more holistic and patient-centred perspective.

Methods: A systematic search of three databases was conducted (PubMed, PsycINFO, and ScienceDirect). Based on the method by which the results of these studies were produced, the studies included were sorted into four categories (quantitative, instrument validation, qualitative, and mixed studies) and subsequently examined using conceptual analysis.

Results: One hundred thirteen articles were included in this research after the screening process. In the quantitative and instrument validation studies, recovery was defined or operationalized in terms of abstinence, the absence of a GD diagnosis, or mild GD severity, or by reference to treatment outcomes or controlled gambling. A meta-synthesis of the results of the qualitative studies revealed four core features of recovery (insight, empowerment and commitment, wellbeing enhancement, and reconsideration of the issue of relapse).

Discussion: Discrepancies in definitions, outcomes, and variables used were evident across studies. Additionally, the quantitative and standardized approaches employed in most studies exhibited severe limitations with regard to defining recovery from the subjective and multidimensional perspectives of people recovering from GD.

Conclusions: This lack of definitional clarity emphasizes the necessity for further qualitative research. This research should encompass multiple stakeholder perspectives to develop a working definition promoting recovery from a holistic, patient-centred, and tailored approach.

背景和目的:尽管康复这一概念在赌博障碍(GD)中越来越受到关注,但人们尚未就其定义达成共识。本范围综述旨在对有关赌博障碍康复的文献进行梳理,找出差距,并从更全面和以患者为中心的角度提出见解:对三个数据库(PubMed、PsycINFO 和 ScienceDirect)进行了系统检索。根据这些研究结果的产生方法,将所收录的研究分为四类(定量研究、工具验证研究、定性研究和混合研究),然后使用概念分析法进行研究:经过筛选,共有 113 篇文章被纳入本研究。在定量研究和工具验证研究中,康复的定义或操作方法是戒断、无 GD 诊断或 GD 严重程度轻微,或参考治疗结果或控制赌博。对定性研究结果的元综合显示了康复的四个核心特征(洞察力、赋权和承诺、幸福感增强以及重新考虑复发问题):讨论:各项研究在定义、结果和使用的变量方面存在明显差异。此外,大多数研究采用的定量和标准化方法在从广东话康复者的主观和多维角度定义康复方面表现出严重的局限性:结论:定义的不明确强调了进一步定性研究的必要性。这项研究应涵盖多个利益相关者的观点,以制定一个有效的定义,从全面、以患者为中心和量身定制的角度促进康复。

Neural correlates of model-based behavior in internet gaming disorder and alcohol use disorder. 网络游戏障碍和酒精使用障碍中基于模型行为的神经相关性。
IF 7.8 1区 医学 Q1 PSYCHIATRY Pub Date : 2024-03-08 Print Date: 2024-03-26 DOI: 10.1556/2006.2024.00006

Background: An imbalance between model-based and model-free decision-making systems is a common feature in addictive disorders. However, little is known about whether similar decision-making deficits appear in internet gaming disorder (IGD). This study compared neurocognitive features associated with model-based and model-free systems in IGD and alcohol use disorder (AUD).

Method: Participants diagnosed with IGD (n = 22) and AUD (n = 22), and healthy controls (n = 30) performed the two-stage task inside the functional magnetic resonance imaging (fMRI) scanner. We used computational modeling and hierarchical Bayesian analysis to provide a mechanistic account of their choice behavior. Then, we performed a model-based fMRI analysis and functional connectivity analysis to identify neural correlates of the decision-making processes in each group.

Results: The computational modeling results showed similar levels of model-based behavior in the IGD and AUD groups. However, we observed distinct neural correlates of the model-based reward prediction error (RPE) between the two groups. The IGD group exhibited insula-specific activation associated with model-based RPE, while the AUD group showed prefrontal activation, particularly in the orbitofrontal cortex and superior frontal gyrus. Furthermore, individuals with IGD demonstrated hyper-connectivity between the insula and brain regions in the salience network in the context of model-based RPE.

Discussion and conclusions: The findings suggest potential differences in the neurobiological mechanisms underlying model-based behavior in IGD and AUD, albeit shared cognitive features observed in computational modeling analysis. As the first neuroimaging study to compare IGD and AUD in terms of the model-based system, this study provides novel insights into distinct decision-making processes in IGD.

背景:基于模型的决策系统和无模型决策系统之间的不平衡是成瘾性障碍的一个共同特征。然而,人们对网络游戏障碍(IGD)是否也存在类似的决策缺陷知之甚少。本研究比较了 IGD 和酒精使用障碍(AUD)中与基于模型和无模型系统相关的神经认知特征:方法:被诊断为 IGD(22 人)和 AUD(22 人)的参与者以及健康对照组(30 人)在功能磁共振成像(fMRI)扫描仪内完成两阶段任务。我们利用计算建模和分层贝叶斯分析对他们的选择行为进行了机理解释。然后,我们进行了基于模型的 fMRI 分析和功能连接分析,以确定各组决策过程的神经相关性:计算建模结果显示,IGD 组和 AUD 组基于模型的行为水平相似。然而,我们观察到两组基于模型的奖赏预测误差(RPE)存在不同的神经相关性。IGD 组表现出与基于模型的 RPE 相关的胰岛特异性激活,而 AUD 组则表现出前额叶激活,尤其是在眶额皮层和额上回。此外,在基于模型的RPE背景下,IGD患者的脑岛与显著性网络中的脑区之间表现出超连接性:研究结果表明,尽管在计算建模分析中观察到了共同的认知特征,但 IGD 和 AUD 基于模型行为的神经生物学机制可能存在差异。作为第一项比较 IGD 和 AUD 基于模型系统的神经影像学研究,本研究为 IGD 的独特决策过程提供了新的见解。

Driving and mobile phone use: Work addiction predicts hazardous but not excessive mobile phone use in a longitudinal study of young adults. 驾驶与手机使用:在一项针对年轻成年人的纵向研究中,工作成瘾可预测危险使用手机的情况,但不能预测过度使用手机的情况。
IF 7.8 1区 医学 Q1 PSYCHIATRY Pub Date : 2024-03-08 Print Date: 2024-03-26 DOI: 10.1556/2006.2024.00007

Background and objectives: Work addiction (WA), characterized by dimensions such as overcommitment, difficulties in detachment from work, and work-life imbalance, is presumed to be associated with increased smartphone usage, even during risky activities like driving. The study investigated the connection between WA and future problematic and hazardous smartphone use, considering personality factors: anxiety, rumination, and worry.

Methods: A three-wave longitudinal study (N = 1,866) was conducted from March to July 2019, June to September 2020, and June to November 2021, involving a representative sample of 18-34-year-old residents in Hungary's capital. The study employed Hungarian versions of the Bergen Work Addiction Scale, Problematic Mobile Phone Use Questionnaire, Ruminative Response Scale, Anxiety subscale of the Brief Symptom Inventory 18, and Penn-State Worry Questionnaire. Additionally, author-developed questions on mobile phone use while driving were included.

Results: At baseline, those at risk for WA showed more frequent mobile phone use while driving at both time points 2 and 3 compared to the non-risk group. Path analyses revealed rumination, anxiety at time 1, and worry at time 2 as significant mediators between baseline WA and mobile phone use while driving at time 3. However, when analyzing all three mediators together, only anxiety at time 1 and worry at time 2 remained significant.

Discussion and conclusion: This study demonstrates that WA predicts future mobile phone use while driving through mediation by anxiety and worry. Our findings add to the growing evidence highlighting the detrimental aspects of WA, emphasizing the need for improved prevention and treatment strategies.

背景和目的:工作成瘾(WA)的特点是过度投入工作、难以从工作中抽身以及工作与生活失衡,据推测,工作成瘾与智能手机使用量的增加有关,甚至在驾驶等危险活动中也是如此。本研究考虑了焦虑、反刍和担忧等人格因素,调查了WA与未来问题性和危险性智能手机使用之间的联系:在2019年3月至7月、2020年6月至9月以及2021年6月至11月期间进行了三波纵向研究(N = 1,866),涉及匈牙利首都18至34岁的代表性居民样本。研究采用了匈牙利语版本的卑尔根工作成瘾量表、问题性手机使用问卷、反刍反应量表、简明症状量表 18 的焦虑分量表和宾州忧虑问卷。此外,还包括作者开发的关于开车时使用手机的问题:结果:基线时,与非风险组相比,WA高危人群在第2和第3时间点开车时使用手机的频率更高。路径分析显示,反刍、时间点 1 的焦虑和时间点 2 的担忧是基线 WA 与时间点 3 驾驶时使用手机之间的重要中介。然而,当对所有三个中介因素进行综合分析时,只有第一时间的焦虑和第二时间的担忧仍具有显著性:本研究表明,通过焦虑和担忧的中介作用,WA 可以预测未来开车时使用手机的情况。我们的研究结果补充了越来越多的证据,凸显了WA的有害方面,强调了改进预防和治疗策略的必要性。

Introduction: The overall prevalence of gambling problems across prison populations is currently unknown. The objective of the present study was therefore to quantitatively synthetize prevalence estimates of gambling problems in prison populations using a random effects meta-analytic model and to investigate if the estimates were moderated by time frame, cut-off levels, and sample size.

Methods: To be included the studies had to report original data on the prevalence of gambling problems in a prison sample and to be written in a European language, whereas data based on abstracts or qualitative reports were excluded. The search ended on December 1, 2023 and were conducted in Web of Science, PubMed, Cinahl, PsycINFO, Embase, Google Scholar, Grey Literature Report, and GreyNet. Risk of bias was assessed with a standardized 10-item measure for epidemiological studies.

Results: A total of 26 studies comprising 9,491 participants were included. The vast majority of the participants were males. The most commonly used instrument for assessment of gambling problems was the South Oaks Gambling Screen. The pooled random-effects gambling problems prevalence estimate was 30.8% (95% CI = 25.1-37.3). The meta-regression analysis showed that none of the three moderator variables (criteria, timeframe, sample size) were related to the gambling problems prevalence. Common limitations of the included studies entailed not being representative nationally or for the target population, lack of randomization, and low response rate. The meta-analysis was restricted to studies published in a European language.

Conclusions: Overall, the studies show that 1 in 3 prisoners has gambling problems and suggests that more emphasis on relevant prevention and treatment is warranted for this population. The study was funded by the Norwegian Competence Center for Gambling and Gaming Research and pre-registered at PROSPERO (CRD42023390552).

导言:目前尚不清楚监狱人群中赌博问题的总体流行率。因此,本研究的目的是利用随机效应元分析模型,对监狱人群中赌博问题的流行率估计值进行定量综合,并研究这些估计值是否受时间框架、截止水平和样本大小的影响:纳入的研究必须报告监狱样本中赌博问题流行率的原始数据,并以欧洲语言撰写,而基于摘要或定性报告的数据则被排除在外。检索截止日期为 2023 年 12 月 1 日,检索范围包括 Web of Science、PubMed、Cinahl、PsycINFO、Embase、Google Scholar、Grey Literature Report 和 GreyNet。对流行病学研究的偏倚风险采用标准化的 10 项衡量标准进行评估:结果:共纳入 26 项研究,9 491 名参与者。绝大多数参与者为男性。最常用的赌博问题评估工具是南橡树赌博筛查。汇总的随机效应赌博问题流行率估计为 30.8%(95% CI = 25.1-37.3)。元回归分析表明,三个调节变量(标准、时间范围、样本大小)均与赌博问题流行率无关。所纳入研究的共同局限性包括:不具有全国或目标人群的代表性、缺乏随机性以及响应率低。荟萃分析仅限于以欧洲语言发表的研究:总体而言,这些研究表明,每三名囚犯中就有一人存在赌博问题,这也表明需要更加重视对这一人群的相关预防和治疗。该研究由挪威赌博和博彩研究能力中心资助,并在PROSPERO(CRD42023390552)进行了预先登记。

Trait anxiety and corresponding neuromarkers predict internet addiction: A longitudinal study. 特质焦虑和相应的神经标志物可预测网络成瘾:纵向研究
IF 7.8 1区 医学 Q1 PSYCHIATRY Pub Date : 2024-03-07 Print Date: 2024-03-26 DOI: 10.1556/2006.2023.00086

Background and aims: The high prevalence of internet addiction (IA) has become a worldwide problem that profoundly affects people's mental health and executive function. Empirical studies have suggested trait anxiety (TA) as one of the most robust predictors of addictive behaviors. The present study investigated the neural and socio-psychological mechanisms underlying the association between TA and IA.

Methods: Firstly, we tested the correlation between TA and IA. Then we investigated the longitudinal influence of TA on IA using a linear mixed effect (LME) model. Secondly, connectome-based predictive modeling (CPM) was employed to explore neuromarkers of TA, and we tested whether the identified neuromarkers of TA can predict IA. Lastly, stressful life events and default mode network (DMN) were considered as mediating variables to explore the relationship between TA and IA.

Findings: A significant positive correlation between TA and IA was found and the high TA group demonstrated higher IA across time. CPM results revealed that the functional connectivity of cognitive control and emotion-regulation circuits and DMN were significantly correlated with TA. Furthermore, a significant association was found between the neuromarkers of TA and IA. Notably, the CPM results were all validated in an independent sample. The results of mediation demonstrated that stressful life events and correlated functional connectivity mediated the association between TA and IA.

Conclusions: Findings of the present study facilitate a deeper understanding of the neural and socio-psychological mechanisms linking TA and IA and provide new directions for developing neural and psychological interventions.

背景和目的:网络成瘾(IA)的高流行率已成为一个世界性问题,对人们的心理健康和执行功能产生了深远影响。实证研究表明,特质焦虑(TA)是成瘾行为最可靠的预测因素之一。本研究探讨了特质焦虑与成瘾行为之间的神经和社会心理机制:首先,我们检验了TA和IA之间的相关性。然后,我们使用线性混合效应(LME)模型研究了TA对IA的纵向影响。其次,采用基于连接体的预测模型(CPM)来探索TA的神经标志物,并检验TA的神经标志物能否预测IA。最后,我们将压力性生活事件和默认模式网络(DMN)视为中介变量,以探讨TA与IA之间的关系:研究发现,TA与IA之间存在明显的正相关,高TA组在不同时期表现出更高的IA。CPM结果显示,认知控制和情绪调节回路与DMN的功能连接与TA显著相关。此外,TA 的神经标记物与 IA 之间也存在明显的关联。值得注意的是,CPM结果均在独立样本中得到了验证。调解结果表明,压力性生活事件和相关功能连通性调解了TA与IA之间的关联:结论:本研究的结果有助于人们更深入地了解TA和IA之间的神经和社会心理机制,并为制定神经和心理干预措施提供了新的方向。
