Official title: VISIONS: Voices Illuminating Solutions for Outdoor Workers' Needs and Safety
Run by Stanford University · NCT07713264 · Data updated 2026-11-12
This trial tests whether adding bilingual Our Voice photovoice participation to standard bilingual occupational health education helps outdoor workers in California better address climate-related health risks.

Is this trial a fit for you?
✓Likely a good fit
Outdoor workers or community members in San Joaquin Valley, Kings County, or Monterey County who are 18+ and can use or be trained to use a bilingual Discovery Tool app.
✕Probably not a fit
Participants who do not engage with the photovoice process or who have minimal exposure to climate-related hazards may experience no additional benefit.

What this trial studies
This randomized controlled trial compares two approaches for outdoor workers and community members: (1) education on heat and air quality risks plus the Our Voice photovoice method using a bilingual mobile app, and (2) the same education without photovoice. Participants are 18 or older and connected to San Joaquin Valley, Kings County, or Monterey County. Outcomes are measured in a consistent way across groups to see if combining participatory research with education leads to greater changes in climate-related attitudes, behaviors, and protective actions. The study uses a two-arm parallel design and targets English- and Spanish-speaking individuals. The lead sponsor is Stanford University and the study is conducted in California.
Why it matters
Potential benefit: If successful, participants could adopt more protective behaviors and influence local policies through community-derived insights.
How similar studies have gone: Previous photovoice-based work has shown promise in rural and community health settings, but this exact combination with occupational health education is relatively novel.
