Outcome Measures

Primary Outcomes (2)

  • Device Acceptability as Measured by the Acceptability of Intervention Measure (AIM)

    The AIM measure is designed to assess the acceptability of a intervention, and has been adapted in relation to the AIRpen. Participants rate statements related to their usage and experience of the AIRpen and AIRpen website, with ratings ranging from "Completely Disagree" (1), to "Completely Agree" (5). Higher scores indicate higher acceptability of the intervention.

    From enrollment to end of 1 hour study period.

  • Device Usability as Measured by a Modified Version of the System Usability Scale (SUS)

    The System Usability Scale is a 10-item measure that address the usability and learnability of a system. The SUS has been modified to reflect the AIRpen intervention. Statements are ranked on a Likert scale for 1-5, with 1 indicating "Strongly Disagree" and 5 indicating "Strongly Agree". Raw scores are converted into a final score that ranges from 0-100, with a larger score indicating greater usability.

    From enrollment until completion of 1 hour study period.

Secondary Outcomes (2)

  • Perceived Stress as Measured by the Perceived Stress Scale (PSS_10)

    From enrollment to the end of the 1 hour study period

  • Physiological Stress as Assessed with Heart Rate Monitoring

    From study enrollment to end of 1 hour study period

Study Arms (3)

Base AIRpen

EXPERIMENTAL

In this arm, participants will utilize an AIRpen after completing an arithmetic based stress test during a decompression period. Participants will engage in diaphragmatic breathing and other stress reducing behaviors like fidgeting or clicking using the AIRpen while physiological data is measured with an ear sensor and audio recordings.

Device: Resistance Breathing Device

Smart AIRpen

EXPERIMENTAL

In this arm, participants will utilize a SMART AIRpen after completing an arithmetic based stress test during a decompression period. Participants will engage in diaphragmatic breathing and other stress reducing behaviors like fidgeting or clicking using the Smart AIRpen while physiological data is measured with an ear sensor and audio recordings.

Device: Electronic Resistance Breathing Device

No AIRpen

NO INTERVENTION

In this arm, participants will be asked to sit quietly following an arithmetic based stress test during a decompression period. Physiological data will be measured with an ear sensor and audio recordings.

Interventions

The AIRpen is a multifunctional stress management tool that helps users engage in diaphragmatic breathing at differing resistance levels, as well as other common stress relieving behaviors such as fidgeting

Base AIRpen

The Smart AIRpen functions just as the original AIRpen device and has been augmented with sensors to measure use patterns to determine whether the AIRpen is being used for fidgeting or breathing.
