Trial Outcomes & Findings for Change in Knowledge After Receiving Personal Air Pollution Results (NCT NCT05160948)
NCT ID: NCT05160948
Last Updated: 2026-07-31
Results Overview
EcoMAPPE participants and their caregivers will be asked to complete a survey to assess their understanding of air pollution and beliefs about science and research before and after receiving their individual study monitoring results collected as part of their participation in EcoMAPPE. Likert scale questions 'On a scale from 1 to 5, 1=strongly disagree, 2 = disagree, 3 = neither disagree nor agree, 4 = agree, 5 = strongly agree

PRIMARY outcome
Timeframe: Baseline and within 30 daysPopulation: Certain questions were pre-specified to be collected only from caregivers, therefore, Adolescent Arms/Groups did not have data collected for these questions (0 participants analyzed)
EcoMAPPE participants and their caregivers will be asked to complete a survey to assess their understanding of air pollution and beliefs about science and research before and after receiving their individual study monitoring results collected as part of their participation in EcoMAPPE. Likert scale questions 'On a scale from 1 to 5, 1=strongly disagree, 2 = disagree, 3 = neither disagree nor agree, 4 = agree, 5 = strongly agree
