Temporal dynamics of teen crisis help-seeking following hurricanes: A structural topic model analysis.
Article in PLOS digital health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Extreme weather events pose significant mental health risks for youth, yet few studies have examined the temporal dynamics of crisis help-seeking following multiple hurricanes using real-time anonymized transcripts. We analyzed 2,149 anonymized crisis text conversations from Louisiana youth (2018-2023) using structural topic modeling (STM) to identify thematic patterns and temporal trajectories following six hurricanes, including Hurricane Ida. Conversations were assigned to the closest hurricane using a temporal proximity algorithm and classified into eight mutually exclusive recovery periods based on days elapsed since landfall, ranging from the immediate hurricane period (days -1 to +2) through beyond one year post-exposure (>365 days). Compound disaster effects (hurricane + COVID-19) were also examined. We identified 12 distinct crisis topics organized into four domains (Crisis, Coping, Stressor, Resource/Process) and documented a systematic "three waves" pattern of post-disaster psychological response. Wave 1 (Immediate: 0-30 days) was characterized by resource-seeking, with Crisis Hotline Protocol (17.4%) and Louisiana Services (9.8%) peaking during active storms. Wave 2 (Delayed: 31-90 days) revealed the emergence of acute crises, with Suicide Ideation & Self-Harm increasing from 5.1% during hurricanes to 8.9% at 61-90 days post-landfall (p = 0.006). Wave 3 (Long-term: 3 + months) was dominated by interpersonal stressors peaking at >12 months, including Relationships (17.8%) and Family Conflict (10.3%), with Abuse & Safety Concerns showing delayed emergence at 9 + months. Compound disasters (74% of sample) were associated with elevated Grief (+3.3 percentage points) and Abuse & Safety Concerns (+1.8 percentage points). Crisis text data reveal distinct temporal phases of youth mental health help-seeking following hurricanes, with a critical delayed suicide ideation peak at 61-90 days. These findings suggest potential windows for stepped-care frameworks and demonstrate the utility of crisis hotline data as a real-time tool for disaster mental health surveillance.
