Reducing Patient Burden and Improving Data Quality With the New Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire

This study randomly assigned 190 patients between the ages of 18 and 80 undergoing surgery for low rectal cancer. Of those randomly assigned, 142 with partially complete surveys were analyzed for selection bias and acceptability, and 95 with complete surveys were analyzed for survey validity. INTERVENTIONS: Patients received either a J-pouch, side-to-end anastomosis, or straight anastomosis. MAIN OUTCOME MEASURE: The study evaluated survey validity measures such as standardized Cronbach α for internal consistency and Spearman correlation coefficients for construct validity, convergent validity, and responsiveness. Univariate analyses were used to assess discriminative validity. RESULTS: Sufficient acceptability, construct, and convergent validity and responsiveness were achieved. All scores showed great internal consistency (Cronbach α>0.8). Superior discriminative ability was demonstrated by significant differences (p 0.8). Una capacidad discriminativa superior fue demostrada por diferencias significativas (p
