<p><strong>Background: </strong>Attention is at the base of more complex cognitive processes, and its deficits can significantly impact safety and health. Attention can be impaired by neurodevelopmental and acquired disorders. One validated theoretical model to explain attention processes and their deficits is the hierarchical model of Sohlberg and Mateer. This model guides intervention development to improve attention following an acquired disorder. Another way to stimulate attention functions is to engage in the daily practice of mindfulness, a multicomponent concept that can be explained by the theoretical model of Baer and colleagues. Mobile apps offer great potential for practicing mindfulness daily as they can easily be used during daily routines, thus facilitating transfer. Laverdière and colleagues have developed such a mobile app called Focusing, which is aimed at attention training using mindfulness-inspired attentional exercises. However, this app has not been scientifically validated.</p><p><strong>Objective: </strong>This research aims to analyze the logical content validity and ecological content validity of the Focusing app.</p><p><strong>Methods: </strong>Logical content validation was performed by 7 experts in neuropsychology and mindfulness. Using an online questionnaire, they determined whether the content of the attention training app exercises is representative of selected constructs, namely the theoretical model of attention by Sohlberg and Mateer and the theoretical model of mindfulness by Baer and colleagues. A focus group was subsequently held with the experts to discuss items that did not reach consensus in order to change or remove them.

Background: Maternal mental health disorders are prevalent, yet many individuals do not receive adequate support due to stigma, financial constraints, and limited access to care. Digital interventions, particularly chatbots, have the potential to provide scalable, low-cost support, but few are tailored specifically to the needs of perinatal individuals.

Objective: This study aimed to (1) design and develop Moment for Parents, a tailored chatbot for perinatal mental health education and support, and (2) assess usability through engagement, usage patterns, and user experience.

Methods: This study used a human-centered design to develop Moment for Parents, a rules-based chatbot to support pregnant and postpartum individuals. In phase 1, ethnographic interviews (n=43) explored user needs to inform chatbot development. In phase 2, a total of 108 pregnant and postpartum individuals were recruited to participate in a pilot test and had unrestricted access to the chatbot. Engagement was tracked over 8 months to assess usage patterns and re-engagement rates. After 1 month, participants completed a usability, relevance, and satisfaction survey, providing key insights for refining the chatbot.

Results: Key themes that came from the ethnographic interviews in phase 1 included the need for trusted resources, emotional support, and better mental health guidance. These insights informed chatbot content, including mood-based exercises and coping strategies. Re-engagement was high (69/108, 63.9%), meaning users who had stopped interacting for at least 1 week returned to the chatbot at least once. A large proportion (28/69, 40.6%) re-engaged 3 or more times. Overall, 28/30 (93.3%) found the chatbot relevant for them, though some noted repetitive content and limited response options.

Conclusions: The Moment for Parents chatbot successfully engaged pregnant and postpartum individuals with higher-than-typical retention and re-engagement patterns. The findings underscore the importance of flexible, mood-based digital support tailored to perinatal needs. Future research should examine how intermittent chatbot use influences mental health outcomes and refine content delivery to enhance long-term engagement and effectiveness.

背景:孕产妇心理健康障碍很普遍,但由于耻辱感、经济限制和获得护理的途径有限,许多人得不到足够的支持。数字干预措施,尤其是聊天机器人,有可能提供可扩展、低成本的支持,但很少有专门针对围产期个体需求的干预措施:本研究旨在:(1)设计和开发 "父母时刻"(Moment for Parents)聊天机器人,这是一款为围产期心理健康教育和支持量身定制的聊天机器人;(2)通过参与度、使用模式和用户体验评估可用性:本研究采用以人为本的设计,开发了基于规则的聊天机器人 Moment for Parents,为孕妇和产后妇女提供支持。在第一阶段,人种学访谈(n=43)探讨了用户需求,为聊天机器人的开发提供了参考。在第二阶段,共招募了 108 名孕妇和产后人士参与试点测试,他们可以不受限制地使用聊天机器人。对参与情况进行了 8 个月的跟踪,以评估使用模式和重新参与率。1 个月后,参与者完成了可用性、相关性和满意度调查,为完善聊天机器人提供了重要见解:第一阶段人种学访谈的关键主题包括对可信资源、情感支持和更好的心理健康指导的需求。这些见解为聊天机器人的内容提供了参考,包括基于情绪的练习和应对策略。重新参与度很高(69/108,63.9%),这意味着停止互动至少一周的用户至少返回聊天机器人一次。很大一部分用户(28/69,40.6%)重新参与了 3 次或更多次。总体而言,28/30(93.3%)的用户认为聊天机器人与他们相关,尽管有些用户注意到了重复的内容和有限的回复选项:父母时刻 "聊天机器人成功地吸引了孕妇和产后人士,其保留和再次参与的模式高于一般模式。研究结果强调了针对围产期需求提供灵活的、基于情绪的数字支持的重要性。未来的研究应探讨间歇性使用聊天机器人如何影响心理健康结果,并完善内容交付以提高长期参与度和有效性。

<p><strong>Background: </strong>Digital mental health interventions may help increase access to psychological treatment for adolescents with anxiety disorders. However, many clinical evaluations of digital treatments report low adherence and engagement and high dropout rates, which remain challenges when the interventions are implemented in routine care. Involving intended end users in the development process through user-centered design methods may help maximize user engagement and establish the validity of interventions for implementation.</p><p><strong>Objective: </strong>This study aimed to describe the methods used to develop a new internet-based cognitive behavioral therapy intervention, CoolMinds, within a user-centered design framework.</p><p><strong>Methods: </strong>The development of intervention content progressed in three iterative design phases: (1) identifying needs and design specifications, (2) designing and testing prototypes, and (3) running feasibility tests with end users. In phase 1, a total of 24 adolescents participated in a user involvement workshop exploring their preferences on graphic identity and communication styles as well as their help-seeking behavior. In phase 2, a total of 4 adolescents attended individual usability tests in which they were presented with a prototype of a psychoeducational session and asked to think aloud about their actions on the platform. In phase 3, a total of 7 families from the feasibility trial participated in a semistructured interview about their satisfaction with and initial impressions of the platform and intervention content while in treatment. Activities in all 3 phases were audio recorded, transcribed, and coded using thematic analysis and qualitative description design. The intervention was continuously revised after each phase based on the feedback.</p><p><strong>Results: </strong>In phase 1, adolescent feedback guided the look and feel of the intervention content (ie, color scheme, animation style, and communication style). Participants generally liked content that was relatable and age appropriate and felt motivating. Animations that resembled "humans" received more votes as adolescents could better "identify" themselves with them. Communication should preferably be "supportive" and feel "like a friend" talking to them. Statements including praise-such as "You're well on your way. How are you today?"-received the most votes (12 votes), whereas directive statements such as "Tell us how your day has been?" and "How is practicing your steps going?" received the least votes (2 and 0 votes, respectively). In phase 2, adolescents perceived the platform as intuitive and easy to navigate and the session content as easy to understand but lengthy.

背景:数字化心理健康干预措施可能有助于增加患有焦虑症的青少年获得心理治疗的机会。然而,许多数字治疗方法的临床评估报告显示,坚持率和参与率较低,辍学率较高,这在常规护理中实施干预时仍然是个挑战。通过以用户为中心的设计方法让目标最终用户参与到开发过程中,可能有助于最大限度地提高用户参与度,并为干预措施的实施建立有效性:本研究旨在描述在以用户为中心的设计框架内开发基于互联网的认知行为疗法干预措施 CoolMinds 所使用的方法:干预内容的开发分为三个迭代设计阶段:(1) 确定需求和设计规范,(2) 设计和测试原型,(3) 与最终用户进行可行性测试。在第一阶段,共有 24 名青少年参加了用户参与研讨会,探讨他们对图形标识和交流方式的偏好以及他们的求助行为。在第二阶段,共有 4 名青少年参加了个人可用性测试,在测试中,他们看到了心理教育课程的原型,并被要求大声思考他们在平台上的行为。在第三阶段,共有 7 个来自可行性试验的家庭参加了半结构式访谈,了解他们在治疗期间对平台和干预内容的满意度和初步印象。所有三个阶段的活动都进行了录音、转录,并采用主题分析和定性描述设计进行了编码。每个阶段结束后,都会根据反馈意见对干预措施进行持续修订:在第一阶段,青少年的反馈意见对干预内容的外观和感觉(即配色方案、动画风格和交流风格)起到了指导作用。参与者普遍喜欢贴近生活、符合年龄特点、具有激励作用的内容。与 "人 "相似的动画获得了更多的选票,因为青少年能更好地 "认同 "这些动画。交流最好是 "支持性的",感觉就像 "朋友 "在与他们交谈。包括表扬在内的话语,如 "你做得很好。你今天好吗?"这样的表扬得票最多(12 票),而 "告诉我们你今天过得怎么样?"和 "你的台阶练习得怎么样了?"这样的指令性语句得票最少(分别为 2 票和 0 票)。在第 2 阶段,青少年认为该平台直观且易于浏览,课程内容易于理解但冗长。在第 3 阶段,家庭普遍对干预内容表示满意,并强调图形材料有助于理解治疗内容。他们的反馈意见帮助确定了需要进一步改进的地方,如编辑材料和增加疗程中的休息时间:结论:在干预措施的开发过程中采用用户参与的做法有助于确保干预措施与最终用户的需求保持一致,并有助于确定干预措施在日常护理实践中实施的有效性。

背景介绍辅助治疗的心理健康应用程序在青少年心理治疗中可以发挥重要作用。它们可以提高青少年的参与度和自主性,在危急情况下提供即时支持,并对治疗工作联盟产生积极影响。然而,心理治疗师却很少使用心理健康应用程序。此外,由于应用程序在心理治疗中的使用有限或根本不存在,人们对影响其融入心理治疗师日常工作的实际障碍和驱动因素知之甚少。为了更好地了解心理健康应用程序应如何设计才能实际使用,有必要探讨心理治疗师对应用程序主要功能和特点的看法,以及影响其融入临床实践的因素:本研究旨在分析心理治疗师在青少年心理治疗中使用移动应用程序时,哪些应用程序功能和特点是必不可少的,并从心理治疗师的角度找出影响心理治疗应用程序整合的主要驱动因素和障碍:我们进行了 3 项可行性研究,在 3 种不同的心理治疗环境中使用 Steps(一款针对青少年的跨诊断治疗辅助应用程序):住院治疗、精神科门诊治疗以及私人诊所心理治疗师的门诊治疗。所有研究均采用定性准实验设计。参与者提供了他们的年龄、职业、工作年限、媒体亲和力、对心理治疗应用程序的态度、感知到的应用程序质量和可行性以及治疗辅助应用程序的实施过程等信息。定性数据采用演绎定性内容分析法进行分析。共有 40 名心理健康专业人员参与了这 3 项研究(研究 1:18 人;研究 2:13 人;研究 3:9 人):所有研究的参与率和应用程序使用率都很低。研究确定了跨诊断、辅助治疗应用程序的六项核心功能:情绪检查、资料库、提醒事项、目标和任务、应急包以及问卷调查。此外,将心理健康应用程序融入日常生活还受到各种驱动因素和障碍的影响。最主要的障碍包括技术问题和实际限制,如时间和资源有限。最重要的驱动因素是治疗质量的明显改善:总体而言,心理治疗师普遍对使用治疗辅助型心理健康应用程序持开放态度。然而,研究参与度和应用程序使用率仍然较低。由于心理治疗师是患者使用心理健康应用程序的守门人,因此在开发和实施此类应用程序时应优先考虑他们的需求:德国临床试验注册中心 DRKS00031258; https://drks.de/search/en/trial/DRKS00031258/details。

<p><strong>Background: </strong>Step count is used to quantify activity in individuals using accelerometers. However, challenges such as difficulty in detecting steps during slow or irregular gait patterns and the inability to apply this method to wheelchair (WC) users limit the broader utility of accelerometers. Alternative device-specific measures of physical activity exist, but their specificity limits cross-applicability between different device sensors.

Using the hitoe system, a smart clothing-based physical activity measurement system, we measured the MSDA of trunk movement and step count. The correlation between MSDA and step count was examined in all participants. Based on their daily living mobility levels, measured using the Functional Independence Measure (FIM), participants were categorized into 6 subgroups: FIM1-4, FIM5 (WC), FIM5 (walking), FIM6 (WC), FIM6 (walking), and FIM7 (walking).

The Shapiro-Wilk test indicated no significant results for MSDA across all subgroups, supporting a normal distribution within these groups. In contrast, the step count data for the WC subgroups showed significant results, indicating a deviation from a normal distribution. Additionally, 10.2% (20/197) of participants recorded zero steps, demonstrating a floor effect in the step count data. The median MSDA values for the 6 subgroups (FIM1-4, FIM5 WC, FIM5 walking, FIM6 WC, FIM6 walking, and FIM7) were 0.006, 0.007, 0.010, 0.011, 0.011, and 0.014, respectively, reflecting their levels of independence based on the FIM mobility scores.

Background: Wearable sensor bracelets have gained interest for their ability to detect symptomatic and presymptomatic infections through alterations in physiological indicators. Nevertheless, the use of these devices for public health surveillance among attendees of large-scale events such as hajj, the Islamic religious mass gathering held in Saudi Arabia, is currently in a nascent phase.

Objective: This study aimed to explore hajj stakeholders' perspectives on the use of wearable sensor bracelets for disease detection.

Methods: We conducted a qualitative, theoretically informed, interview-based study from March 2022 to October 2023 involving a diverse sample of hajj stakeholders, including technology experts, health care providers, and hajj service providers. The study was guided by the task-technology fit model and the unified theory of acceptance and use of technology to provide a comprehensive understanding of the factors influencing the acceptance and use of the technology. Semistructured in-depth interviews were used to capture perspectives on using wearable sensor bracelets for infectious disease detection during hajj. Thematic analysis of interview transcripts was conducted.

Results: A total of 14 individuals were interviewed. In total, 4 main themes and 13 subthemes emerged from the study, highlighting crucial challenges, considerations, recommendations, and opportunities in the use of wearable sensor bracelets for the presymptomatic detection of infectious diseases during hajj. Implementing wearable sensor bracelets for disease detection during hajj faces obstacles from multiple perspectives, encompassing users, implementing stakeholders, and technological factors. Hajj stakeholders were concerned about the substantial financial and operational barriers. The motivation of implementing stakeholders and users is essential for the acceptance and uptake of devices during hajj. Successful integration of wearables into the hajj surveillance system depends on several factors, including infrastructure, device features, suitable use cases, training, and a smooth organizational integration process.

Conclusions: This study provides valuable insights into the potential opportunities and challenges of adopting wearable sensor bracelets for disease detection during hajj. It offers essential factors to consider and important suggestions to enhance comprehension and ensure the effective implementation of this technology.

Assessing the Causal Association Between COVID-19 and Graves Disease: Mendelian Randomization Study.
IF 2 Q3 HEALTH CARE SCIENCES & SERVICES Pub Date : 2025-04-08 DOI: 10.2196/66003
Hui Nian, Yu Bai, Hua Yu

Background: Graves disease (GD) is an autoimmune thyroid disorder characterized by hyperthyroidism and autoantibodies. The COVID-19 pandemic has raised questions about its potential relationship with autoimmune diseases like GD.

Objective: This study aims to investigate the causal association between COVID-19 and GD through Mendelian randomization (MR) analysis and assess the impact of COVID-19 on GD.

Methods: We conducted an MR study using extensive genome-wide association study data for GD and COVID-19 susceptibility and its severity. We used stringent single nucleotide polymorphism selection criteria and various MR methodologies, including inverse-variance weighting, MR-Egger, and weighted median analyses, to assess causal relationships. We also conducted tests for directional pleiotropy and heterogeneity, as well as sensitivity analyses.

Results: The MR analysis, based on the largest available dataset to date, did not provide evidence supporting a causal relationship between COVID-19 susceptibility (odds ratio [OR] 0.989, 95% CI 0.405-2.851; P=.93), COVID-19 hospitalization (OR 0.974, 95% CI 0.852-1.113; P=.70), COVID-19 severity (OR 0.979, 95% CI 0.890-1.077; P=.66), and GD. Tests for directional pleiotropy and heterogeneity, as well as sensitivity analyses, supported these findings.

Conclusions: This comprehensive MR study does not provide sufficient evidence to support a causal relationship between COVID-19 and the onset or exacerbation of GD. These results contribute to a better understanding of the potential association between COVID-19 and autoimmune diseases, alleviating concerns about a surge in autoimmune thyroid diseases due to the pandemic. Further research is warranted to explore this complex relationship thoroughly.

背景:巴塞杜氏病(GD)是一种以甲状腺功能亢进和自身抗体为特征的自身免疫性甲状腺疾病。COVID-19大流行引发了人们对其与GD等自身免疫性疾病潜在关系的质疑:本研究旨在通过孟德尔随机分析(MR)研究 COVID-19 与 GD 之间的因果关系,并评估 COVID-19 对 GD 的影响:我们利用广泛的全基因组关联研究数据,对GD和COVID-19易感性及其严重程度进行了MR研究。我们采用了严格的单核苷酸多态性选择标准和各种 MR 方法(包括逆方差加权、MR-Egger 和加权中位数分析)来评估因果关系。我们还进行了方向性多义性和异质性检验以及敏感性分析:基于迄今最大可用数据集的MR分析未提供证据支持COVID-19易感性(比值比[OR] 0.989,95% CI 0.405-2.851;P=.93)、COVID-19住院率(OR 0.974,95% CI 0.852-1.113;P=.70)、COVID-19严重程度(OR 0.979,95% CI 0.890-1.077;P=.66)与广东之间的因果关系。定向多效性和异质性检验以及敏感性分析均支持这些结果:这项全面的磁共振研究没有提供足够的证据支持 COVID-19 与 GD 发病或加重之间的因果关系。这些结果有助于更好地理解 COVID-19 与自身免疫性疾病之间的潜在关联,减轻了人们对大流行导致自身免疫性甲状腺疾病激增的担忧。我们有必要开展进一步的研究,以深入探讨这种复杂的关系。

Using Large Language Models to Automate Data Extraction From Surgical Pathology Reports: Retrospective Cohort Study.
IF 2 Q3 HEALTH CARE SCIENCES & SERVICES Pub Date : 2025-04-07 DOI: 10.2196/64544

Background: Popularized by ChatGPT, large language models (LLMs) are poised to transform the scalability of clinical natural language processing (NLP) downstream tasks such as medical question answering (MQA) and automated data extraction from clinical narrative reports. However, the use of LLMs in the health care setting is limited by cost, computing power, and patient privacy concerns. Specifically, as interest in LLM-based clinical applications grows, regulatory safeguards must be established to avoid exposure of patient data through the public domain. The use of open-source LLMs deployed behind institutional firewalls may ensure the protection of private patient data. In this study, we evaluated the extraction performance of a locally deployed LLM for automated MQA from surgical pathology reports.

Objective: We compared the performance of human reviewers and a locally deployed LLM tasked with extracting key histologic and staging information from surgical pathology reports.

Methods: A total of 84 thyroid cancer surgical pathology reports were assessed by two independent reviewers and the open-source FastChat-T5 3B-parameter LLM using institutional computing resources. Longer text reports were split into 1200-character-long segments, followed by conversion to embeddings. Three segments with the highest similarity scores were integrated to create the final context for the LLM. The context was then made part of the question it was directed to answer. Twelve medical questions for staging and thyroid cancer recurrence risk data extraction were formulated and answered for each report. The time to respond and concordance of answers were evaluated. The concordance rate for each pairwise comparison (human-LLM and human-human) was calculated as the total number of concordant answers divided by the total number of answers for each of the 12 questions. The average concordance rate and associated error of all questions were tabulated for each pairwise comparison and evaluated with two-sided t tests.

Results: Out of a total of 1008 questions answered, reviewers 1 and 2 had an average (SD) concordance rate of responses of 99% (1%; 999/1008 responses). The LLM was concordant with reviewers 1 and 2 at an overall average (SD) rate of 89% (7%; 896/1008 responses) and 89% (7.2%; 903/1008 responses). The overall time to review and answer questions for all reports was 170.7, 115, and 19.56 minutes for Reviewers 1, 2, and the LLM, respectively.

Conclusions: The locally deployed LLM can be used for MQA with considerable time-saving and acceptable accuracy in responses. Prompt engineering and fine-tuning may further augment automated data extraction from clinical narratives for the provision of real-time, essential clinical insights.

Background: HIV index case testing (ICT) aims to identify people living with HIV and their contacts, engage them in HIV testing services, and link them to care. ICT implementation has faced challenges in Malawi due to limited counseling capacity among lay health care workers (HCWs). Enhancing capacity through centralized face-to-face training is logistically complex and expensive. A decentralized blended learning approach to HCW capacity-building, combining synchronous face-to-face and asynchronous digital modalities, may be an acceptable way to address this challenge.

Objective: The objective of this analysis is to describe factors influencing HCW anticipated acceptability of blended learning using the Technology Acceptance Model (TAM).

Methods: This formative qualitative study involved conducting 26 in-depth interviews with HCWs involved in the ICT program across 14 facilities in Machinga and Balaka, Malawi (November-December 2021). Results were analyzed thematically using TAM. Themes were grouped into factors affecting the 2 sets of TAM constructs: perceived usefulness and perceived ease of use.

Results: A total of 2 factors influenced perceived usefulness. First, HCWs found the idea of self-guided digital learning appealing, as they believed it would allow for reinforcement, which would facilitate competence. They also articulated the need for opportunities to practice and receive feedback through face-to-face interactions in order to apply the digital components. In total, 5 factors influenced perceived ease of use. First, HCWs expressed a need for orientation to the digital technology given limited digital literacy. Second, they requested accessibility of devices provided by their employer, as many lacked personal devices. Third, they wished for adequate communication surrounding their training schedules, especially if they were going to be asynchronous. Fourth, they wished for support for logistical arrangements to avoid work interruptions. Finally, they wanted monetary compensation to motivate learning, a practice comparable with offsite trainings.

Conclusions: A decentralized blended learning approach may be an acceptable method of enhancing ICT knowledge and skills among lay HCWs in Malawi, although a broad range of external factors need to be considered. Our next step is to integrate these findings into a blended learning package and examine perceived acceptability of the package in the context of a cluster randomized controlled trial.
