The participants attended the 6-week group-based CDSMP, with sessions of 2.5 hours duration offered once per week, facilitated by the respiratory nurse and the physiotherapist–investigator who had both undertaken leader training. The sessions were interactive with lecturettes, problem solving, brain storming, action planning, and reporting-back activities. There were up to 12 participants per cohort. A comparison of the CDSMP lecturette topics with those previously delivered in PR education is shown in Table 1
