• Introduction: Spleen Deficiency Syndrome (SDS) is recognized as one of the most common Traditional Chinse Medicine (TCM) syndromes in patients with colorectal cancer (CRC). However so far there is no existing patient-reported outcome (PRO) to evaluate SDS. Our study aimed to develop and validate a PRO TCM-SDS scale for CRC in China. Methods: We developed an initial 8-item TCM-SDS scale for CRC based on literature review and consultation with experts. We then pilot tested the scale (n = 40) and performed item revision. We conducted a survey study among CRC patients from oncology clinics at a TCM Hospital to further determine the reliability and validity of the scale. Results: Among 100 patients finally enrolled and analyzed in the survey study, 46% were female with median age of 60 years old, 77% had left side tumors and 23% had stage IV disease. Factor loading indicated that there were three domains within TCM-SDS scale. The final TCM-SDS scale involves 5 items including “I feel loss of appetite,” “I feel abdomen fullness,” “I feel my arms and legs lack strength,” “I feel short of breath when talking,” and “My stool is formless” (Cronbach’s alpha coefficient 0.76). We calculated the total score of the scale by summing the 5 individual items and normalizing them to a value maximum of 10, with higher scores indicating greater burden of spleen deficiency syndrome. The average spleen deficiency score for all patients was 3.55 ± 1.54. Among them, those who had stage IV disease had higher scores than stage I-III patients (4.30 vs 3.38, P = .015). Test-retest reliability after 2 weeks showed Pearson coefficient of 0.67 and all items were highly related (P < .001). Compared with healthy controls, CRC patients had significantly higher spleen deficiency scores (3.55 vs 3.23, P = .045). Conclusion: The patient-reported TCM-SDS scale for CRC showed adequate initial reliability and validity. The development of the scale provided an outcome measurement tool, which could facilitate future studies to better evaluate the role of TCM in treating CRC.
