Patient-based assessment in dyspepsia: development and validation of Dyspepsia Symptom Severity Index (DSSI)

Patient-based assessment in dyspepsia: development and validation of Dyspepsia Symptom Severity Index (DSSI)

Digestive Diseases and Sciences 45(6): 1172-1179

This paper describes the development and testing of a new self-report measure, the Dyspepsia Symptom Severity Index (DSSI), for assessing the severity of symptoms commonly associated with dyspepsia. The instrument was based on the literature, focus groups, and feedback from gastroenterologists; 48 patients and 24 controls participated in testing. Patients completed the DSSI and a symptom diary to test concurrent validity; one-week reproducibility was evaluated in 21 stable patients.
