Summary

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.

Detailed description

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.

Interventions

Type	Name	Description
OTHER	Home Air Quality	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).
