Abstract: 【Abstract】Objective To develop a health promotion lifestyle scale for peritoneal dialysis (PD) patients and to test the reliability and validity of the scale in order to provide a basis for evaluating the lifestyle in PD patients. Methods Through literature search and semi- structured interview, the conceptional dimension of the scale and the main source of item pool were established. The primary scale was formed after consultation through an expert meeting. Finally, the scale was verified and improved after a pilot survey. Results The health promotion lifestyle scale for PD patients included 6 dimensions and 35 items. The reliability of the questionnaire was 0.898, and the Cronbach's coefficient was 0.777～0.815. The retest reliability coefficient of the scale was 0.905, and the Cronbach's magnitude coefficient of each dimension was 0.762～0.805. The content validity index (CVI) was 0.800～1.000, and the average CVI was 0.867. Conclusion This scale has better reliability and validity, and is a suitable tool to assess health behavior for PD patients.
