Résumé	The Patient Assessment of Constipation Quality of Life (PAC-QoL) is a validated, patient-reported outcome measure designed to assess the impact of functional constipation on physical, psychological, and social well-being. Developed by Marquis and colleagues in 2005, the PAC-QoL comprises 28 items organized into four domains: Physical Discomfort, Psychosocial Discomfort, Worries and Concerns, and Satisfaction. The PAC-QoL is responsive to treatment and widely used in constipation clinical trials and practice.	The Gastroparesis Cardinal Symptom Index (GCSI) is a validated, patient-reported outcome measure specifically designed to assess symptom severity in gastroparesis. Developed by Revicki and colleagues in 2003, the GCSI captures the three cardinal symptom clusters of gastroparesis: nausea and vomiting, postprandial fullness, and early satiety, plus bloating and stomach distension. The 9-item questionnaire is responsive to treatment changes and is increasingly used in clinical trials and practice to monitor gastroparesis progression and therapy response.
