Background

Internet addiction and attention control increasingly influence how individuals across age groups perceive social support. This study explored the psychological impact of excessive internet use and attentional regulation within a diverse Indian population.

Objectives

The study aimed (a) to examine perceptual distortions of social support across the lifespan as a function of individual differences in internet addiction and attention control; (b) to explore how socio-demographic factors such as sex and socioeconomic status (SES) influence attention control and perceived social support in the context of internet addiction; and (c) to investigate how age and SES jointly shape patterns of internet addiction, attention control, and perceived social support in a multi-age cohort.

Methods

A cross-sectional design was used to collect data from 399 participants in Mysuru through purposive sampling. Standardized instruments included the Internet Addiction Test, Attention Control Scale, and Multidimensional Scale of Perceived Social Support. Analyses were conducted using SPSS v.27, employing multiple regression and MANOVA.

Results

The regression model significantly predicted perceived social support, F(2, 396) = 20.87, p = 0.001, R² = 0.095. Internet addiction was a significant negative predictor of perceived social support (β = –.260, p = 0.001) meanwhile attention control was not (β = 0.099, p = 0.053). MANOVA showed significant effects of age (p = 0.013) and an Age × SES interaction (p = 0.019) on internet addiction. sex and SES main effects were non-significant.

Conclusion

Perceptual distortions of social support are not simply the result of screen time, but are mediated by age and class. These findings underscore internet addiction as a psychosocial outcome shaped by unequal digital environments.

网络成瘾和注意力控制越来越多地影响着不同年龄组的个体对社会支持的看法。本研究探讨了在不同的印度人口中过度使用互联网和注意力调节的心理影响。目的：本研究旨在(a)考察网络成瘾和注意力控制的个体差异对整个生命周期中社会支持的感知扭曲；(b)探讨性别和社会经济地位（SES）等社会人口因素如何影响网络成瘾背景下的注意控制和感知社会支持；(c)研究年龄和社会经济地位如何共同影响多年龄队列中网络成瘾、注意力控制和感知社会支持的模式。方法采用横断面设计，采用目的抽样的方法对399名参与者进行资料收集。标准化工具包括网络成瘾测试、注意控制量表和感知社会支持多维量表。采用SPSS v.27进行分析，采用多元回归和方差分析。结果回归模型显著预测感知社会支持，F(2,396) = 20.87, p = 0.001, R2 = 0.095。网络成瘾是感知社会支持的显著负向预测因子（β = -）。260, p = 0.001)，而注意控制不存在（β = 0.099, p = 0.053）。方差分析显示，年龄（p = 0.013）和年龄与社会经济地位的交互作用（p = 0.019）对网络成瘾有显著影响。性别和社会经济地位的主效应不显著。结论社会支持知觉扭曲不单纯是屏幕时间的结果，而受年龄和阶层的中介作用。这些发现强调了网络成瘾是由不平等的数字环境形成的一种社会心理后果。

Considering the pervasive integration of smartphones into the daily lives and high prevalence of problematic smartphone phone use (PSU) among emerging adults, there is an urgency for an integrated perspective to understand their PSU for better intervention insights. This study aims to apply a multi-level theoretical framework, the Differential Susceptibility to Media Effects Model (DSMM), to PSU and evaluate not only the direct effects of dispositional (i.e., neuroticism), social (i.e., family adaptability), and developmental factors (i.e., inclusion of smartphone in the self [ISS]) on PSU but also the potential indirect effect of ISS. We obtained a sample of 801 Chinese emerging adults (559 females; M_age = 19.02 and SD_age = 0.88) through a one-year longitudinal study with two surveys (at wave 1 [W1] and wave 2 [W2]). Hierarchical regression analysis indicated that all baseline susceptibility factors (neuroticism [W1], family adaptability [W1], and ISS [W1]) significantly predicted PSU (W2) after controlling for both demographics and PSU (W2). The results of structural equation modeling further suggested that neuroticism (W1) and family adaptability (W1) were longitudinally associated with ISS (W2), which was in turn associated with PSU (W2). This study provided not only longitudinal evidence to support the application of DSMM to explain PSU but also insights into interventions using targeted approaches.

考虑到智能手机在日常生活中的普遍融入以及新兴成年人中智能手机使用问题（PSU）的高患病率，迫切需要从综合的角度来了解他们的PSU，以获得更好的干预见解。本研究旨在将媒介效应差异敏感性模型（DSMM）这一多层次理论框架应用于PSU，不仅评估性格因素（如神经质）、社会因素（如家庭适应性）和发展因素（如将智能手机纳入自我[ISS]）对PSU的直接影响，还评估其潜在的间接影响。我们通过为期一年的两次调查（第1波[W1]和第2波[W2]），获得了801名中国新兴成年人（559名女性，Mage = 19.02, SDage = 0.88）的样本。分层回归分析表明，在控制人口统计学和PSU （W2）后，所有基线易感因素（神经质[W1]、家庭适应性[W1]和ISS [W1]）均显著预测PSU （W2）。结构方程模型结果进一步表明，神经质（W1）和家庭适应性（W1）与ISS （W2）呈纵向相关，ISS （W2）与PSU （W2）呈纵向相关。这项研究不仅提供了纵向证据来支持应用DSMM来解释PSU，而且还提供了使用有针对性的方法进行干预的见解。

Background

Cannabis has shown mixed results in its association with alcohol urge, which may be explained by individual differences. One such factor, working memory capacity (WMC) is associated with drug-related cue reactivity and implicated in alcohol use and problems. In the current study, we examined whether WMC moderates the acute effect of cannabis on alcohol urge in a randomized placebo-controlled crossover trial.

Methods

Participants aged 21 to 44 (N = 125, 32 % female) reporting heavy alcohol use and cannabis use ≥ twice weekly completed a laboratory protocol across three days where they smoked a placebo, 3.1 % delta-9 tetrahydrocannabinol (THC), and 7.2 % THC cannabis cigarette. Participants were asked to rate their alcohol urge pre and post smoking. Prior to the experimental sessions, participants completed WMC measures including the n-back and the complex span tasks, operation span (OS) and symmetry span (SS).

Results

Those with higher WMC, as assessed via the SS task, reported significantly lower alcohol urge after smoking the 7.2 %, but not the 3.1 %, THC dose, relative to placebo. Performance on the OS task was not associated with alcohol urge. Lower WMC as determined via n-back scores was associated with higher alcohol urge overall, but n-back scores did not moderate the impact of cannabis on alcohol urge.

Conclusion

Findings suggest individuals with higher but not lower working memory experience lower alcohol urge under acute effects of cannabis. Although cannabis is increasingly perceived as a substitute for alcohol, individuals with lower working memory may be less likely to experience such benefits when attempting to reduce their drinking.

大麻与酒精冲动的关系显示出不同的结果，这可以用个体差异来解释。其中一个因素是，工作记忆容量（WMC）与药物相关的线索反应有关，并与酒精的使用和问题有关。在当前的研究中，我们在一项随机安慰剂对照交叉试验中研究了WMC是否能调节大麻对酒精冲动的急性影响。方法年龄在21岁至44岁之间（N = 125, 32%为女性）报告重度饮酒和大麻使用≥每周两次，完成为期三天的实验室方案，其中他们吸食安慰剂，3.1% δ -9四氢大麻酚（THC）和7.2% THC大麻烟。参与者被要求对吸烟前和吸烟后的酒精冲动进行评分。实验前，被试完成了n-back和复杂跨度任务、操作跨度（OS）和对称跨度（SS）。结果通过SS任务评估的WMC较高的受试者在吸烟7.2% THC剂量后的酒精冲动显著降低，而在吸烟3.1% THC剂量后的酒精冲动则显著降低。在OS任务中的表现与酒精冲动无关。通过n-back评分确定的较低的WMC总体上与较高的酒精冲动有关，但n-back评分并没有缓和大麻对酒精冲动的影响。结论在大麻的急性作用下，工作记忆较高而非较低的个体酒精冲动较低。虽然大麻越来越被认为是酒精的替代品，但工作记忆较差的人在试图减少饮酒量时可能不太可能体验到这种好处。

This study investigates whether parenting styles can buffer the intergenerational transmission of substance use. Using a person-centered analytic strategy with 4,280 adolescent–parent dyads in Brazil, we applied Latent Class Analysis to identify substance use profiles in both generations and modeled their association using Latent Transition Analysis. Parental and adolescent profiles were strongly aligned, especially among abstainers. However, this similarity was not deterministic: authoritative parenting significantly reduced adolescents’ likelihood of polysubstance use – even among high-risk parents. Authoritarian parenting also reduced this risk but increased alcohol-specific transmission. Permissive and neglectful styles showed no protective effects. These findings underscore the role of parenting style and highlight the value of family-based interventions to disrupt intergenerational substance use patterns.

本研究探讨父母教养方式是否能缓冲物质使用的代际传递。我们采用以人为中心的分析策略，对巴西的4280对青少年父母进行分析，应用潜在类别分析来确定两代人的物质使用情况，并使用潜在转变分析对其关联进行建模。父母和青少年的情况非常一致，尤其是在戒酒者中。然而，这种相似性并不是决定性的：权威型父母显著降低了青少年使用多种物质的可能性——即使在高风险父母中也是如此。专制教育也降低了这种风险，但增加了酒精特异性传播。纵容型和忽视型没有保护作用。这些发现强调了养育方式的作用，并强调了以家庭为基础的干预措施对破坏代际物质使用模式的价值。

As recreational cannabis increases among United States adults, there is growing interest in understanding potential health co-morbidities. Although past work supports cannabis use and eating disorder comorbidity, and cannabis enhances appetite and reward responses to food, little is known about how specific cannabis use patterns may relate to binge eating and other eating disorder symptoms. The purpose of this study is to identify distinct subgroups of recreational cannabis users based on several use characteristics, including subjective changes to appetite and hedonic properties of food using latent profile analysis, and to examine differences across profiles in binge eating, other eating disorder symptoms, and emotion regulation. Participants (N = 435, male = 189) were adults recruited through Prolific who endorsed past-month cannabis use and completed a battery of self-report measures assessing cannabis use characteristics, eating changes while using cannabis, eating disorder symptoms, and emotion regulation. Results identified four profiles: “Infrequent Users, Moderate Eating Changes, Low Risk,” “Intense Users, Low Eating Changes, Mild Risk,” “High-Risk Coping Users, Strong Eating Changes,” and “Frequent Users, Slight Eating Changes, Mild Risk.” All profiles reported more binge eating symptoms while under the influence of cannabis; the “High Risk Coping Users, Strong Eating Changes” profile reported the most severe sober binge eating, eating disorder, and emotion regulation difficulties. Findings highlight the utility of person-centered approaches for capturing co-morbidity risk and may help guide screening and intervention tools for determining eating disorder risk among those using cannabis.

随着娱乐性大麻在美国成年人中越来越多，人们对了解潜在的健康合并症越来越感兴趣。虽然过去的工作支持大麻使用和饮食失调共病，并且大麻增强食欲和对食物的奖励反应，但对于具体的大麻使用模式与暴饮暴食和其他饮食失调症状之间的关系知之甚少。本研究的目的是根据几种使用特征（包括使用潜在特征分析对食欲和食物享乐特性的主观变化）确定娱乐性大麻使用者的不同亚组，并检查暴饮暴食、其他饮食失调症状和情绪调节的不同特征。参与者（N = 435，男性= 189）是通过多产招募的成年人，他们认可过去一个月的大麻使用，并完成了一系列自我报告措施，评估大麻使用特征、使用大麻时的饮食变化、饮食失调症状和情绪调节。结果确定了四种情况：“不经常使用，饮食变化中等，风险低”，“频繁使用，饮食变化低，风险轻度”，“高风险应对用户，饮食变化强烈”和“频繁使用，饮食变化轻微，风险轻度”。在大麻的影响下，所有档案都报告了更多的暴食症状；“高风险应对使用者，强烈的饮食变化”报告了最严重的清醒暴饮暴食，饮食失调和情绪调节困难。研究结果强调了以人为中心的方法在捕获合并症风险方面的效用，并可能有助于指导筛选和干预工具，以确定大麻使用者的饮食失调风险。

Background: Substance use is commonly documented among human trafficking (HT) survivors in emergency department (ED) settings. Multiple substance use disorders (poly-SUD) are associated with poor health and psychosocial outcomes. This study identified latent classes and demographic covariates of HT-related ED visits by the types of SUDs documented in survivors’ medical records. Methods: We used cross-sectional data from the United States 2019–2021 Nationwide Emergency Department Sample, including visits of patients aged 12–64 years with an ICD-10-CM code documenting either sex or labor exploitation (N = 4,212). A bias-adjusted three-step latent class analysis was conducted, with SUDs documented via ICD-10-CM codes included as indicators in the model. Results: The optimal three-class solution had superior fit based on pre-selected indicators, low classification error, and acceptable entropy. The largest class comprised 76.01 % of the sample and showed a lower predicted probability of the SUD classes considered. The second largest class (17.27 %) was characterized by high predicted probability of stimulant use disorder with moderately high predicted probability of opioid use disorder. The smallest class (6.72 %) was characterized by high predicted probability of each SUD considered. Class membership was differentially associated with disposition from the ED, nicotine use disorder, and income. Conclusions: Although most ED visits were classified as having relatively low probability of SUD, nearly one quarter of the sample had high risk of either stimulant use disorder or high poly-SUD. Poly-SUD in HT survivors is associated with increased risk of hospitalization. Findings provide direction for tailoring intervention programs to support SUD recovery among HT survivors.

背景：在急诊科（ED）设置的人口贩运（HT）幸存者中，物质使用是普遍记录的。多种物质使用障碍（polysud）与健康状况不佳和社会心理结局相关。本研究通过幸存者医疗记录中记录的sud类型确定了ht相关ED就诊的潜在类别和人口统计学协变量。方法：我们使用了来自美国2019-2021年全国急诊科样本的横断面数据，包括12-64岁的就诊患者，其ICD-10-CM代码记录了性别或劳动剥削（N = 4,212）。进行了偏差校正的三步潜在分类分析，通过ICD-10-CM代码记录的sud作为模型的指标。结果：基于预选指标的最优三级方案拟合度好，分类误差小，熵可接受。最大的类别占样本的76.01%，并且显示出考虑的SUD类别的较低预测概率。第二大类别（17.27%）的特点是兴奋剂使用障碍的高预测概率和阿片类药物使用障碍的中等高预测概率。最小的类别（6.72%）的特点是每个SUD的预测概率都很高。班级成员与ED倾向、尼古丁使用障碍和收入存在差异。结论：尽管大多数ED就诊被归类为发生SUD的概率相对较低，但近四分之一的样本存在兴奋剂使用障碍或高度多发SUD的高风险。HT幸存者的Poly-SUD与住院风险增加相关。研究结果为定制干预方案提供了方向，以支持HT幸存者的SUD康复。

Objective

Sociodemographic disparities in SUD treatment need and receipt among women inform public health initiatives. While rates of SUD among pregnant women are lower than those who are not pregnant, an investigation of whether and how sociodemographic disparities of SUD treatment need and receipt among pregnant women can further accelerate SUD related risk prevention for both mothers and babies.

Method

We analyzed data from pregnant women who completed the 2015–2019 National Survey of Drug Use and Health (unweighted N = 3,461). We used logistic regression models to test odds of 1) past-year SUD treatment need and 2) SUD treatment receipt among pregnant women. Models included age, race and ethnicity, income, education, marital status, sexual orientation, mental illness, and survey year as independent variables; interactions between income and racial/ethnic group were also included.

Results

7.8% of pregnant women had a SUD and 1.2% (20% of those with treatment need) received SUD treatment. Unmarried, bisexual (vs heterosexual), non-Hispanic/Latina Black (vs non-Hispanic/Latina White), and women with mental illness showed increased odds of a SUD. An income by race interaction indicated Hispanic/Latina women of lower income were less likely to have SUD than White women of higher income. Of those with a treatment need, married women and women aged 18–25 (vs 26–34 and 35+) had lower odds of receiving treatment.

Conclusion

SUD treatment need differed among pregnant women by marital status, sexual orientation, race and ethnicity, and mental illness, as did treatment receipt by marital status and age. Specialized outreach and engagement strategies are needed to ensure equitable access to SUD treatment during pregnancy.

目的：妇女在SUD治疗需求和接受方面的社会人口差异为公共卫生举措提供信息。虽然妊娠妇女的SUD发生率低于未妊娠妇女，但调查妊娠妇女在SUD治疗需求和接受方面的社会人口差异是否以及如何可以进一步加快母婴SUD相关风险的预防。方法：我们分析完成2015-2019年全国药物使用与健康调查的孕妇数据（未加权N = 3,461）。我们使用logistic回归模型来检验1)过去一年的孕妇SUD治疗需求和2)接受SUD治疗的几率。模型包括年龄、种族、民族、收入、教育程度、婚姻状况、性取向、精神疾病和调查年份作为自变量；收入和种族/族裔群体之间的相互作用也包括在内。结果：7.8%的孕妇发生了SUD， 1.2%（占有治疗需求的20%）接受了SUD治疗。未婚、双性恋（vs异性恋）、非西班牙裔/拉丁裔黑人（vs非西班牙裔/拉丁裔白人）和患有精神疾病的女性患SUD的几率增加。种族相互作用的收入表明，收入较低的西班牙裔/拉丁裔女性患SUD的可能性低于收入较高的白人女性。在有治疗需求的人群中，已婚女性和年龄在18-25岁的女性（相对于26-34岁和35岁以上的女性）接受治疗的几率较低。结论：孕妇的婚姻状况、性取向、种族、民族、精神疾病等因素对SUD治疗需求存在差异，婚姻状况、年龄等因素对SUD治疗需求存在差异。需要专门的外展和参与战略，以确保在怀孕期间公平获得SUD治疗。

Purpose

Some college women report using electronic cigarettes (e-cigarettes) for weight control. Social media frequently promotes e-cigarettes for weight management and reinforces unrealistic body ideals, which may foster body dissatisfaction and unhealthy weight control behaviors. Given college women’s high rates of social media and e-cigarette use, this study examined the relationship between college women’s social media use, thin-ideal internalization, and e-cigarette use for weight control.

Methods

College women (N = 343, M_age = 20.88) who used e-cigarettes for weight control reasons participated in an online survey that measured their social media use, levels of thin-ideal internalization, and e-cigarette use behaviors. Mediation analysis was performed to test whether thin-ideal internalization mediated the relationship between social media use and e-cigarette use for weight control.

Results

Social media use positively predicted e-cigarette use for weight control purposes (B = 0.12, p < 0.001). Thin-ideal internalization fully mediated this relationship (indirect effect: B = 0.06, 95 % CI [.03, 0.10]) as the direct effect became non-significant when accounting for the mediator (direct effect: B = 0.06, p = 0.10). Greater social media use significantly increased thin-ideal internalization (B = 1.01, p < 0.001), which subsequently predicted greater e-cigarette use for weight control purposes (B = 0.06, p < 0.001).

Conclusion

Findings highlight that greater social media exposure among college women strengthens thin-ideal internalization, which drives e-cigarette use for weight control purposes. These findings signal the importance of regulating e-cigarette content on social media, as well as prevention efforts that address social media’s thin-ideal content and promote body positivity.

一些大学女生报告说，她们用电子烟来控制体重。社交媒体经常宣传电子烟用于体重管理，并强化不切实际的身体理想，这可能会助长对身体的不满和不健康的体重控制行为。鉴于大学女生使用社交媒体和电子烟的比例很高，本研究调查了大学女生使用社交媒体、瘦型理想内化和使用电子烟控制体重之间的关系。方法使用电子烟控制体重的大学女性（N = 343, Mage = 20.88）参加了一项在线调查，测量了她们的社交媒体使用情况、瘦型理想内化水平和电子烟使用行为。进行中介分析以检验瘦理想内化是否介导了社交媒体使用与电子烟使用体重控制之间的关系。社交媒体使用正预测电子烟用于控制体重（B = 0.12, p < 0.001）。薄理想内化完全介导了这种关系（间接效应：B = 0.06, 95% CI）。03, 0.10])，当考虑中介因素时，直接效应变得不显著（直接效应：B = 0.06, p = 0.10）。更多的社交媒体使用显著增加了瘦理想的内在化（B = 1.01, p < 0.001），这随后预示着更多的电子烟用于控制体重（B = 0.06, p < 0.001）。研究结果强调，大学女性更多的社交媒体曝光加强了苗条理想的内化，从而推动了电子烟的使用，以控制体重。这些发现表明了规范社交媒体上电子烟内容的重要性，以及解决社交媒体上的瘦身理想内容和促进身体积极性的预防工作。

Problematic social media use (PSMU) is increasingly conceptualized as a behavioral addiction involving attentional bias toward social media icons. Although fear of missing out (FoMO) contributes to PSMU maintenance, its dynamic interactive role in attentional bias dynamics remains unclear. Guided by the I-PACE model and attentional bias theory, this study examined whether and when FoMO modulates gaze-based attentional bias toward social media icons in PSMU. 912 university students completed online screening for PSMU and FoMO; 55 meeting PSMU criteria (M_age = 19.60) were categorized into high- or low-FoMO groups. Participants performed a visual dot-probe task with social/non-social app icons while eye-tracking recorded gaze behavior across four 500 ms time windows. Results revealed FoMO significantly interacted with attentional bias in two critical phases: During early processing (0–500 ms), the PSMU/high-FoMO group exhibited attentional orienting deceleration to social media icons, whereas PSMU/low-FoMO showed attentional maintenance. In later processing (1000–1500 ms), PSMU/high-FoMO demonstrated attentional vigilance-maintenance, while PSMU/low-FoMO displayed avoidance. These findings indicate FoMO exerts a temporally dynamic interaction effect on attentional bias in PSMU—characterized by initial orienting delays followed by sustained attentional engagement with social media icons. This supports reconceptualizing FoMO as a core psychological mechanism that reinforces PSMU through biased attentional dynamics, advancing theoretical alignment with the I-PACE framework.

有问题的社交媒体使用（PSMU）越来越被定义为一种行为成瘾，涉及对社交媒体图标的注意力偏见。虽然错失恐惧（fear of missing out, FoMO）有助于PSMU维持，但其在注意偏置动力学中的动态交互作用尚不清楚。在I-PACE模型和注意偏向理论的指导下，本研究考察了FoMO是否以及何时调节了PSMU中基于注视的对社交媒体图标的注意偏向。912名大学生完成PSMU和FoMO在线筛查；55名符合PSMU标准（Mage = 19.60）的患者被分为高fomo组和低fomo组。参与者使用社交/非社交应用程序图标进行视觉点探测任务，同时眼动追踪记录了四个500毫秒时间窗口内的凝视行为。结果表明，FoMO与注意偏向在两个关键阶段显著相互作用：在加工早期（0 ~ 500 ms）， PSMU/高FoMO组对社交媒体图标的注意定向减速，而PSMU/低FoMO组对社交媒体图标的注意保持。在加工后期（1000 ~ 1500 ms）， PSMU/高fomo表现为注意警戒维持，而PSMU/低fomo表现为回避。这些研究结果表明，FoMO对psmu的注意偏差具有时间动态交互作用，其特征是最初的定向延迟，随后是对社交媒体图标的持续注意参与。这支持将FoMO重新定义为一种核心心理机制，通过偏向性注意动力学加强PSMU，推进与I-PACE框架的理论一致性。

Background

Given increased rates of problematic alcohol use among middle-older age adults, novel, accessible alcohol interventions are needed. This pilot RCT explored the feasibility, acceptability, and preliminary effectiveness of personalised smartphone-delivered alcohol approach bias modification (ApBM) in Australians (≥55 years) drinking at hazardous/harmful levels (AUDIT ≥ 8).

Method

Double-blinded parallel two-arm pilot RCT in Victoria, Australia (July 2022–January 2023). Community-based ≥ 55-year-olds received ‘AAT-App+’ (n = 96) or sham training (n = 92) over four-weeks. Feasibility was defined as recruitment of ≥ 100 participants within the recruitment window and 50 % adherence to four sessions. Acceptability was defined as User Version Mobile Application Rating Scale (uMARS) mean scores ≥ 3. The primary preliminary effectiveness outcome was past-week standard drinks at week four relative to baseline.

Results

Feasibility and acceptability were good, with n = 188 recruited, 69 % training adherence, and ‘good’ uMARS functionality/aesthetics and ‘acceptable’ quality ratings among responders (n = 94). Retention rates were 56 % for primary effectiveness outcome. Linear mixed modelling using intention-to-treat analysis showed a significant mean reduction of 6.9 past-week standard drinks relative to baseline overall (p<.001), but no significant group-by-time interaction at the primary endpoint (β = −1.90, p=.43, 95 %CI [−6.62, 2.82]). The groups differed significantly favouring ApBM after two-weeks of training (β = -5.28, p=.03, 95 %CI [−10.01;−0.56]). There were no adverse events throughout the training window.

Conclusion

Personalised smartphone ApBM is feasible and acceptable to middle-to-older adults, but we found no evidence to suggest it reduced alcohol consumption any more than sham-training beyond the acute period. Further work is needed prior to large-scale RCT progression to mitigate attrition and optimise study design.

背景：考虑到中老年成人中问题酒精使用率的增加，需要新的、可获得的酒精干预措施。该试点RCT探讨了在澳大利亚（≥55岁）饮酒达到危险/有害水平（AUDIT≥8）的人群中，使用个性化智能手机提供的酒精方法偏差修正（ApBM）的可行性、可接受性和初步有效性。方法：在澳大利亚维多利亚进行双盲平行双臂先导随机对照试验（2022年7月- 2023年1月）。社区≥55岁的患者接受为期四周的“AAT-App+”（n = 96）或假训练（n = 92）。可行性定义为在招募窗口内招募≥100名参与者，并有50%的依从性参加4个疗程。可接受性定义为用户版移动应用评定量表（uMARS）平均分≥3分。主要的初步有效性结果是在第四周相对于基线的过去一周的标准饮酒量。结果：可行性和可接受性良好，招募了n = 188人，69%的培训依从性，响应者的uMARS功能/美学和质量评分为“良好”（n = 94）。主要疗效的保留率为56%。使用意向治疗分析的线性混合模型显示，相对于基线总体而言，过去一周的标准饮酒量平均减少了6.9。结论：个性化智能手机ApBM对于中老年人来说是可行和可接受的，但我们没有发现证据表明，在急性期之后，它比假训练更能减少饮酒量。在大规模的随机对照试验进展之前，需要进一步的工作来减轻损耗和优化研究设计。
