Symptom Perception

Patients in the PEF feedback arm will receive a one-time session including asthma management education, discussion of their asthma symptoms, review of individual PEF results and perception of symptoms, and problem-solving techniques to improve asthma self-management. After the session, the participants in this arm will be able to view in the display of the AM2 device their PEF values and will be instructed to mentally note their actual results with their pre-effort estimated BPF. They will also set a motivational message for themselves that will appear on the device.

General asthma education, AM2 training, and positive counseling, but no discussion linking asthma symptom perception to SMB. Following the session, these participants will use the AM2 to track PEF actual and perceived values twice per day, but they will be blinded to the actual PEF values. Control arm patients will see a standard motivational message appear on the screen of the AM2 device.
