About this trial

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.

  • 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 \[will insert more info (how often, method etc once MP revises protocol\].

Trial outcomes

Primary outcomes

1

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

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.

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

Secondary outcomes

1

Change in social cohesion and collective efficacy as assessed by the Social Cohesion and Self-Efficacy scale.

Each participant will complete the Social Cohesion and Self-Efficacy scale at baseline, immediately after the intervention photovoice activity or control education activity, and 6 months. The scale includes 6 questions answered on a five point rating scale ranging from 1 = "strongly disagree" (the least favorable perception) to 5= "strongly agree" (the most favorable perception). Higher scores indicate greater social cohesion and self-efficacy.

Time frame
Change in social cohesion and collective efficacy from baseline to immediately after the intervention photovoice activity or control education activity and 6 months
2

Change in climate change hope and agency as assessed by the Climate Change Hope Scale (CCHS).

Each participant will complete the CCHS at baseline, immediately after the intervention photovoice activity or control education activity, and 6 months. The scale consists of 11 statements to which participants respond to on an 8-point scale. The scale goes from -3 (strongly disagree) to 0 (neutral) to 3 (strongly agree) and one last choice of X which means "I do not think climate is changing." Higher scores indicate greater hope.

Time frame
Change in climate change hope and agency from baseline to immediately after the intervention photovoice activity or control education activity and 6 months
