Voices Illuminating Solutions for Outdoor Workers' Needs and Safety

50 participantsStarted 2026-07-29

Plain-language summary

The goal for this multidisciplinary randomized controlled trial (RCT) is to actively and meaningfully engage outdoor workers (can include agricultural workers, construction workers, landscaping, wildland firefighters, fire cleanup crews, etc.) and community members in describing the impact of climate change on their lives and working conditions in San Joaquin Valley, Kings County, and Monterey County. Participants will be randomly assigned to one of two study arms: (1) the Intervention Group, which will receive bilingual (Spanish and English) Cal/OSHA educational materials and engage in the Our Voice participatory action research (photovoice) method using a bilingual (Spanish and English) mobile application, or (2) the Control Group, which will only receive bilingual (Spanish and English) Cal/OSHA educational materials. Core outcomes will be measured identically across both groups to allow direct comparison of the two approaches. Using the "Our Voice participatory action research method" and Cal/OSHA educational materials, the investigators will learn about participants' attitudes, behaviors, and actions in response to changing climate in the counties and evaluate whether the education and photovoice approach is more impactful than traditional didactic Cal/Osha education only.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Change in self-efficacy as assessed by the Individual Community-Related Empowerment (ICRE) Scale.

Timeframe: Change in self-efficacy from baseline to immediately after the intervention photovoice activity or control education activity and at 6 months
