We developed an instrument to measure the satisfaction of lung transplant recipients with home monitoring. The survey
comprised 15 items, each scored on a five-point Likert-type scale (from strongly disagree to strongly agree). Three
additional free-text items enabled subjects to provide comments. The survey had a scoring range of 15–75. In a test group
of 43 patients, the internal consistency (Cronbach’s alpha) was 0.93 overall for all questions. The intra-class correlation for
scores from the same 27 patients approximately 2.5 months apart was 0.77 for the total score. The survey was used
to evaluate subject satisfaction in a randomized controlled trial of a computerized algorithm for triaging lung transplant
recipients. Surveys were mailed to 50 study subjects and were returned by 32 (64% return rate). Ninety percent of
respondents were satisfied with the home monitoring programme and would recommend it to other patients.
