Assessing quality of life in Crohn’s disease: development and validation of the Crohn’s Life Impact Questionnaire (CLIQ)

Purpose Despite the significant impact of Crohn’s disease (CD) on patients’ physical and emotional well-being, no CD-specific patient-reported outcome (PRO) measure is available for determining the efficacy of interventions. The objective of the study was to develop and validate the Crohn’s Life Impact Scale (CLIQ), the first such measure.
