Objective To develop an exercise training decision aid for chronic obstructive pulmonary disease(COPD) patients in order to improve patients'exercise compliance and decision quality.

Methods Based on the guidance of Ottawa decision theory, the preliminary version of the exercise training decision aid for COPD patients was developed through two rounds of expert correspondence based on the results of previous studies by our research team and literature analysis. A user assessment of the acceptance of the decision aid was conducted and the final version of the decision aid for COPD patients was developed.

Results Two rounds of expert consultation were conducted, and the authority coefficient of both rounds was 0.827, including a judgment coefficient of 0.853 and a familiarity coefficient of 0.800. The coordination coefficient (Kendall's W) of the two rounds of expert evaluation was significant at P < 0.001. The user evaluation test showed that the tool had good acceptability and practicality, and the final revised version of the exercise training decision aid for COPD patients contained 6 primary indicators and 25 secondary indicators.

Conclusion The exercise training decision aid for COPD patients developed in this study is scientific and practical, and can help patients better understand information related to exercise training decisions, reduce decision conflicts, and improve decision quality.
