Brief 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.

Condition or disease Intervention/treatment
Asthma Environmental Exposure Home Environment Related Disease Other: Home Air Quality

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.

Intervention Details:
  • 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).

Primary Outcome Measures :
  1. Home environmental exposure to Volatile organic compounds [ Time Frame: Measured continuously for 14 days ]
    Degree of home exposures to volatile organic compounds as measured by the Awair home air quality monitor

  2. Home environmental exposure to particulate matter (PM) [ Time Frame: Measured continuously for 14 days ]
    Degree of home exposures to PM2.5 as measured by the Awair home air quality monitor

  3. Asthma control [ Time Frame: Assessed daily for 14 days ]
    Forced Expiratory Volume (FEV) Percent predicted as measured by ZEPHYRx home spirometer

Secondary Outcome Measures :
  1. Usability of study tools [ Time Frame: 14 days ]
    Adapted System Usability Scale, 30 items assessing usability of the ZEPHYRx home spirometer, Awair home air quality monitor, and the EMA - with response options of 1= Strongly agree to 5=Strongly Disagree

  2. Compliance with Ecological Momentary Assessment (EMA) prompts [ Time Frame: Compliance over 4-hour periods for 14 days ]
    Frequency of responses to daily scheduled, random, and air quality triggered EMA prompts
