TUMOR, RECRUITMENT
In total, 97 individuals were screened for eligibility, of whom 6 had ISI of 14 or lower, 3 had insomnia for less than 3 months, 4 were engaged in night shift work, 1 reported a comorbid tumor, and 1 failed to attend screening after enrollment. A total of 82 participants (mean [SD] age, 49.67 [14.49] years; 61 [74.4%] females) were enrolled and were equally assigned to the sleep education and DCBT-I groups; 5 individuals did not complete the 6-week treatment, 1 individual did not complete the 1-month follow-up, 1 individual did not complete the 3-month follow-up, and 2 individuals did not complete the 6-month follow-up. Thus, 77 individuals (mean [SD] age, 50.13 [13.49] years; 56 females) completed the 6-week program and 73 patients completed the entire clinical trial. Therefore, 77 participants, including 39 participants in the sleep education group and 38 participants in the DCBT-I group, were included in the full analysis data set. At baseline, there was no difference in ISI scores between groups (mean [SD] ISI score: sleep education, 20.9 [3.3]; DCBT-I: 20.8 [3.7]). The participant recruitment flowchart is shown in
