NCT04922697

Brief Summary

This clinical trial will conduct an educational intervention to promote knowledge of and preventive health behaviors related to personal air pollution exposure. Air pollution is n ubiquitous environmental exposure that is associated with harmful health effects including lung cancer. The educational intervention is comprised of 2 educational videos that include information regarding air pollution, health effects, and personal preventive health behaviors to reduce air pollution exposure and the use of a wearable air pollution sensor. The knowledge gained from this study may inform future research that will be designed to promote awareness of air pollution and its health effects.

Outcome Measures

Primary Outcomes (2)

  • Changes in knowledge regarding air pollution

    Will calculate the proportion of the items that were answered correctly. McNemar's tests will be used to calculate differences in the proportion of participants answering air pollution knowledge items correctly at baseline and at week 5.

    At baseline and week 5

  • Changes in air pollution preventive health behaviors

    Will calculate summary scores for air pollution preventive health behaviors and paired t-test to determine intervention effectiveness at baseline and at week 5.

    At baseline and week 5

Secondary Outcomes (13)

  • Changes in perceived barriers

    At baseline and week 5

  • Changes in perceived benefits

    At baseline and week 5

  • Changes in perceived susceptibility

    At baseline and week 5

  • Changes in perceived severity

    At baseline and week 5

  • Changes in self-efficacy

    At baseline and week 5

  • +8 more secondary outcomes

Study Arms (1)

Prevention (educational videos, questionnaires)

EXPERIMENTAL

Participants watch 2 educational videos during week 3 regarding air pollution, health effects, and personal preventive health behaviors to reduce air pollution exposure. Participants will use wearable air pollution sensors. Participants will complete questionnaires at weeks 1 and 5.
