On TikTok, content assumed to promote user engagement is delivered in a hyperindividually curated manner through a proprietary algorithm. Mental health providers have raised concerns about TikTok's potential role in promoting inaccurate self-diagnoses, pathologizing normal behaviors, and fostering new-onset symptoms after exposure to illness-related content, such as tic-like movements linked to conversion or factitious disorders. The accuracy of posttraumatic stress disorder (PTSD)-related content with respect to conveying symptoms, diagnosis, and treatment deserves further investigation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;This study aimed to characterize the accuracy of PTSD-related TikTok content.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;In February 2022, a search was conducted on TikTok using the hashtag #PTSD, and the 100 most-liked videos were retrieved. Videos were excluded if they were in a non-English language, duplicated, unrelated to PTSD, lacked audio, or contained nonfunctioning links. A publicly available Python package (TikTokPy) was used to scrape available metadata (views, shares, etc). Using the Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-AV), videos were independently coded by 2 reviewers for the overall accuracy of the video (useful, personal experience, or misleading), whether the creator self-identified as a health care professional, symptoms mentioned, and overall video understandability and actionability. A third reviewer was consulted in the rare instances of coding disagreements.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Of the 100 included videos, 29 were classified as useful, 59 were classified as personal experience (subjective experience without outright inaccuracies), and 12 were classified as misleading. The degree to which PTSD-related information was accurate was not associated with its understandability, actionability, or user engagement. Besides useful videos being longer (mean 88.7, SD 63.1 seconds) than personal experience videos (mean 42.7, SD 44.5 seconds), no group differences in video metadata were observed across the number of views, likes, shares, or comments (P&gt;.05). While self-identified HCPs were more likely to post useful content, they also contributed to 33% (4/12) of misleading videos. Changes in cognition and mood were the most frequently reported symptoms of PTSD (38/100, 38% of videos).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Our findings were roughly consistent with previous studies of mental health-related TikTok content accuracy, although this is variable by diagnosis.

Previous Bayesian network research showed that it might be relevant to tailor PA interventions based on demographic factors such as gender, revealing differences in determinants' roles between subpopulations. In order to optimize tailoring, one needs to understand the differences between subpopulations based on different characteristics. Building on this, this study examines age, education level, and PA impairment as key moderators, as these factors might influence PA engagement and intervention responsiveness. Older adults, for example, rely more on habitual behavior, lower-educated individuals may face challenges due to lower health literacy and socioeconomic inequalities, and individuals with PA impairment, defined as functional impairments restricting PA, may face unique barriers to PA. Understanding differences based on these factors is crucial for optimizing interventions and ensuring effectiveness across diverse populations.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;This study investigates, by means of Bayesian networks, differences in PA intervention mechanisms of subpopulations based on age, education level, and PA impairment.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Subpopulation-specific subsets from an integrated dataset of 5 studies are analyzed, including demographics, experimental group assignment, and PA and sociocognitive measures at baseline, short term, and long term. The relevant subpopulations are defined based on age, education level, and PA impairment.

Similar structures of determinants affect short-term PA, ultimately causing effects in the long term, where intention and habit are directly related to PA for most subpopulations. With respect to age-based differences, the interventions influence PA less via attitude cons and planning for older than younger people. Looking at the level of education, planning and intrinsic motivation are less influential for low-educated participants compared with high- or medium-educated participants, whereas more influence takes place through attitude pros for this low-educated group with respect to maintaining effects in the long term.

The worst performing among the 5 models was the CNN, with an R2 of 93.71% and a maximum RMSE of 0.79. Neonatal mortality in Ethiopia is forecasted to be 23.20 (PI 22.20-24.40) per 1000 live births in 2025 and 19.80 (PI 17.10-22.80) per 1000 live births in 2030.</p><p><strong>Conclusions: </strong>This study revealed that national and international targets for neonatal mortality cannot be realized if the current trend continues. This highlights the need for urgent interventions to strengthen the health system to fasten the decline rate of neonatal mortality and collaborative effort with concerned stakeholders for improved and responsive neonatal and child health services in order to achieve these targets.</p>","PeriodicalId":74345,"journal":{"name":"Online journal of public health informatics","volume":"17 ","pages":"e66798"},"PeriodicalIF":1.1,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12377635/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144981649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
