The purposes of this study are to determine the practicality of using home indoor air quality monitoring and a smartphone app to identify home air quality changes and how these changes affect adults with asthma.
The aims of this feasibility study are: 1) determine the feasibility and usability of: (a) ecological momentary assessment (EMA) to assess self-report residential environmental exposures and asthma symptoms, (b) home monitoring of objective environmental exposures (total volatile organic compounds \[VOCs\], particulates \[PM2.5\]), and lung function (home spirometry); 2a) assess the frequency and degree of residential environmental exposures (e.g., disinfectants/cleaners, second-hand smoke) via (a) self-reported data, and (b) home monitoring objective measures, 2b) assess the level of asthma control as indicated by self-reported asthma symptoms and lung function; and 3) explore associations of self-reported and objective measures of residential environmental exposures with self-reported and objective measures of asthma control. Participants will receive an indoor air quality monitor and a home spirometer to measure VOCs, PM2.5, and forced expiratory volume percent predicted, respectively. EMA will be collected using a personal smartphone and EMA software platform. Participants' will be sent scheduled and random EMA notifications to assess asthma symptoms, environmental exposures, lung function, and mitigation strategies. After the 14-day data collection period, participants will respond to survey items related acceptability, appropriateness, and feasibility.

This study will assess the feasibility and usability of ecological momentary assessment (EMA) to capture the context of real time behaviors and environmental exposures that impact indoor environments. In addition, the study will assess the feasibility and usability of providing participants with a readily available indoor home air quality monitor to continuously capture total volatile organic compounds (VOCs) and particulates (PM2.5).

Episodes Per Day
Number of episodes per day that the residential VOCs exceeded 333 ppb and/or PM2.5 exceeded 15 mg/m3, as measured by the Awair home air quality monitor
Time frame: Measured daily for 14 days
Home Spirometry Completed
Number of participants completing daily home spirometry over 14 days.
Time frame: Assessed daily for 14 days
Integration of Study Components
Participants were asked one survey item to assess if the various components of the study were well integrated. Response options ranged from 0=Strongly disagree to 4=Strongly agree. The score was multiplied by 25; scores could range from 0-100. A higher score indicated that the study components were well integrated.
Time frame: 14 days
Ecological Momentary Assessment (EMA) Surveys
Number of participants completing air quality triggered EMA surveys
Time frame: 14 days
