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.
