Trial Outcomes & Findings for Atlas:Text Messaging Program With Weather Alerts, Local Resources & Insights for Addressing Climate Change (NCT NCT06995755)
NCT ID: NCT06995755
Last Updated: 2025-06-26
Results Overview
A 3-item measure of response efficacy that assessed individual, community, and governmental/policy level efficacy for mitigating climate change. It is measured using a Likert scale, with total scores ranging from 3 to 15. Higher scores reflect a better outcome.

Atlas Users
All participants were provided with access to the intervention (atlas)
atlas: A theoretically-grounded, highly individualized text messaging intervention that 1) provided information on current climate-related and environmental risks (e.g., high temperatures, air quality alerts, asthma triggers etc.) that might adversely affect a user's current health conditions; 2) linked users to local zip-code matched resources to mitigate their specific risk (e.g., cooling centers, hurricane shelters); 3) implemented a full range of best practices in tailored health behavior change communications to personalize ongoing communications regarding the link between human actions and extreme weather based on the user's level of concern about and belief in climate change; and 4) provided customized actionable tips for addressing climate change to promote climate efficacy at the individual, community, and policy/advocacy level based on the user's level of motivation.

PRIMARY outcome
Timeframe: Pretest (baseline) and Posttest (30 day follow-up)Population: 36 users completed baseline \& follow-up and did not have a maximum score on response efficacy measure (a score of 15), in which case they were excluded from the primary outcome analyses.
A 3-item measure of response efficacy that assessed individual, community, and governmental/policy level efficacy for mitigating climate change. It is measured using a Likert scale, with total scores ranging from 3 to 15. Higher scores reflect a better outcome.

SECONDARY outcome
Timeframe: Pretest (baseline) and Posttest (30 day follow-up)Population: 16 of the 46 users reported max scores in confidence thus were not included in outcome analysis.
This 3-item scale assesses an individual's confidence level in taking at least one climate friendly action in the next month. Ratings of confidence will be made on a 5-point Likert scale (1=not at all; 5=extremely confident). Raw scores range from a minimum of 3 to a maximum of 15, with higher scores indicating better outcomes.
