Expectations of breathlessness influence behaviour and symptom perception, but the accuracy of these expectations remains unclear. The aim of this study was to examine the relationship between expected and experienced breathlessness, the moderating role of mental states, determinants of expectation accuracy and the influence of recent symptoms on future expectations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this longitudinal study, 83 participants with chronic breathlessness rated expected and experienced breathlessness (on 0\u201310 numerical rating scales (NRS)) using a mobile ecological momentary assessment app over 7\u2005days.
