Interventions

• Receive education on heat and air quality health risks — BEHAVIORAL
  Participants will receive Cal/OSHA educational materials covering heat and air quality risks for outdoor workers \[will insert more info (how often, method etc once MP revises protocol\].
• Participate in Photovoice and climate health risk education — BEHAVIORAL
  Participants will engage in the full Our Voice photovoice program, including training on the Discovery Tool, a Discovery Walk, attendance at a Community Discovery Meeting, and receive the same Cal/OSHA educational materials \[will insert more info (how often, method etc once MP revises protocol\].

Study Details

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.

Arms

• Active Comparator: Control
  Participants will receive bilingual (Spanish and English) Cal/OSHA educational materials about improving awareness of air quality risks, promoting protective behaviors, and fostering community empowerment.
• Experimental: Intervention
  Participants will receive the same bilingual (Spanish and English) Cal/OSHA educational materials from Control arm but also engage in the Our Voice participatory action research (photovoice) method using a bilingual (Spanish and English) mobile application.

Primary Outcome Measure

Change in self-efficacy as assessed by the Individual Community-Related Empowerment (ICRE) Scale. [ Time Frame: Change in self-efficacy from baseline to immediately after the intervention photovoice activity or control education activity and at 6 months ]
