About this trial

This is an interventional prevention trial for Lung Carcinoma

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Adults 18 years or older: The evidence for personal strategies to reduce air pollution exposure has been focused on adults
  • Live in Seattle, WA: The study is designed to focus on Seattle, WA such as using EnviroFlash alerts
  • Own a smartphone: The participant requires a smartphone to setup the Flow app for the air pollution sensor
  • Not traveling in the near-term: The study is designed to assess air pollution patterns in the local Seattle area
  • Leave your home for at least 7 hours per week: Participants will use a wearable air pollution sensor to measure air pollutant levels from indoor and outdoor sources

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Prevention (educational videos, questionnaires)

Arm Description

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.

Outcomes

Primary Outcome Measures

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.
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.

Secondary Outcome Measures

Changes in perceived barriers
Summary scores for perceived barriers (guided by the Health Belief Model) will be calculated from participant questionnaire responses by summing the scores across the relevant scale. Paired t-tests will determine changes in perceived barriers at baseline and week 5.
Changes in perceived benefits
Summary scores for perceived benefits (guided by the Health Belief Model) will be calculated from participant questionnaire responses by summing the scores across the relevant scale. Paired t-tests will determine changes in perceived benefits at baseline and week 5.
Changes in perceived susceptibility
Summary scores for perceived susceptibility (guided by the Health Belief Model) will be calculated from participant questionnaire responses by summing the scores across the relevant scale. Paired t-tests will determine changes in perceived susceptibility at baseline and week 5.
Changes in perceived severity
Summary scores for perceived severity (guided by the Health Belief Model) will be calculated from participant questionnaire responses by summing the scores across the relevant scale. Paired t-tests will determine changes in perceived severity at baseline and week 5.
Changes in self-efficacy
Summary scores for self-efficacy (guided by the Health Belief Model) will be calculated from participant questionnaire responses by summing the scores across the relevant scale. Paired t-tests will determine changes in self-efficacy at baseline and week 5.
Changes in cues to action
Will calculate frequencies for each cue to action (guided by the Health Belief Model). McNemar's tests will be used to calculate differences in the proportion of participants regarding each cue to action at baseline and week 5.
Changes in air pollutant levels measured using the Flow 2 personal air quality sensor
Paired t-tests will determine changes in air pollutant levels at baseline and week 2 vs. week 4 and week 5.
Intervention feasibility (accessibility)
Will report descriptive statistics for intervention accessibility based on responses to the relevant questionnaire items at week 5.
Intervention feasibility (acceptability)
Will report descriptive statistics for intervention acceptability based on responses to the relevant questionnaire items at week 5.
Intervention feasibility (demand)
Will report descriptive statistics for intervention demand based on responses to the relevant questionnaire items at week 5.
Intervention feasibility (uptake, sensor upload completion)
Will report descriptive statistics the proportion of participants completing sensor uploads.
Intervention feasibility (uptake, educational video viewing)
Will report descriptive statistics for the proportion of viewing educational videos at week 3.
Intervention feasibility (uptake, questionnaire completion)
Will report descriptive statistics for the proportion of completing the questionnaires at baseline and week 5.

5. Study Description

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.
Detailed Description
OUTLINE: Participants watch 2 educational videos during week 3 regarding air pollution, health effects, and personal preventive health behaviors to reduce air pollution exposure. Participants complete questionnaires at weeks 1 and 5.
