Educational Interventions for Air Pollution

(VISIONS Trial)

This trial aims to understand how climate change affects outdoor workers and community members in specific California counties. It will compare two approaches: one group will receive bilingual educational materials about air quality risks, while the other group will receive the same materials and use a mobile app to share photos and stories about their experiences (Participate in Photovoice and climate health risk education). The researchers aim to determine if this interactive method increases awareness and engagement with climate issues. This trial suits outdoor workers and community members in San Joaquin Valley, Kings County, or Monterey County who can use a smartphone app or a provided phone to participate. As an unphased trial, it offers participants the chance to contribute to important research on climate change awareness and engagement.

Research has shown that the Photovoice method, used in this trial, is generally safe for participants. Studies have found that using Photovoice in schools can increase environmental awareness and enhance learning. Reports of negative effects from participating in Photovoice activities are absent, indicating it is well-tolerated. This method has succeeded in similar community and educational programs. Participants often report positive experiences, such as gaining more knowledge and becoming more involved with environmental issues. Therefore, the educational part of the trial is considered safe for participants.¹²³⁴⁵

Researchers are excited about this trial because it explores innovative educational interventions to address air pollution awareness and health risks. Unlike traditional methods that rely solely on distributing educational materials, this approach incorporates the Our Voice participatory action research method, known as photovoice, using a bilingual mobile app. This interactive method empowers participants by involving them in documenting and discussing environmental issues, potentially leading to more informed and engaged communities. By combining standard educational content with a participatory approach, the trial aims to enhance community involvement and promote proactive behaviors toward air quality improvement.

Research has shown that the Photovoice method, which participants in the intervention arm of this trial will use, can enhance environmental health education, particularly for farmworkers. This method allows individuals to use photography to capture and discuss issues such as air pollution and climate change, fostering deeper understanding and engagement. Studies have found that methods like Photovoice effectively increase awareness about air quality and empower communities to take action. Although limited data exists on Photovoice's effectiveness specifically for outdoor workers, its success in other community settings suggests it could be beneficial. These educational methods can make information more relatable and actionable, potentially leading to safer behaviors in response to climate change.⁶⁷⁸⁹¹⁰
