简要总结

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.

详细描述

This study uses a randomized controlled trial (RCT) design with two parallel arms to evaluate whether combining participatory action research with occupational health education produces greater changes in climate-related attitudes, behaviors, and protective actions compared to occupational health education alone. The study targets outdoor workers and community members across California: San Joaquin Valley, Kings and Monterey Counties, regions where outdoor workers face disproportionate exposure to climate-related health hazards including extreme heat and degraded air quality.

Intervention

The Intervention Group will engage in the "Our Voice photovoice program," a community-based participatory action research methodology developed at Stanford University. Our Voice uses a mobile application called the Discovery Tool, which allows participants to document features of their local environment by taking photos and recording written or audio reflections in real time. The app is available in multiple languages, including English and Spanish. Participants in the Intervention Group will complete three sequential activities:

Discovery Tool Training: a live or pre-recorded individual or small group session (by phone, Zoom, or in-person) led by a Stanford RA, orienting participants to the photovoice approach and app use

Discovery Walk: an independent walk in their home or work neighborhood to document environmental features relevant to climate and health using the Discovery Tool

研究组 & 干预措施

Control

Active Comparator

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.

干预措施: Receive education on heat and air quality health risks (Behavioral)

Intervention

Experimental

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.

干预措施: Participate in Photovoice and climate health risk education (Behavioral)

结局指标

主要结局

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

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

Each participant will complete the Individual Community-Related Empowerment (ICRE) at baseline, immediately after the intervention photovoice activity or control education activity, and 6 months. The ICRE Scale is an 18-item measure of empowerment capturing the following five dimensions: self-efficacy (personal confidence in capacity to change one's community), intention (desire to engage with or for the community), participation (actual community involvement), motivation (beliefs surrounding community engagement), and critical awareness (perceived seriousness of community issues). Response options are on a five point rating scale ranging from 1 = "strongly agree" (the most favorable perception) to 5= "strongly disagree" (the most unfavorable perception). Lower raw scores indicate greater empowerment.

次要结局

  • Change in social cohesion and collective efficacy as assessed by the Social Cohesion and Self-Efficacy scale.(Change in social cohesion and collective efficacy from baseline to immediately after the intervention photovoice activity or control education activity and 6 months)
  • Change in climate change hope and agency as assessed by the Climate Change Hope Scale (CCHS).(Change in climate change hope and agency from baseline to immediately after the intervention photovoice activity or control education activity and 6 months)
