The FDI is a measure of the degree to which children experience difficulty in physical and psychosocial functioning due to their physical health status. Respondents are asked to rate how much physical difficulty was perceived for a variety of everyday activities. Both child-report and parent-report versions are available.

The Pain Response Inventory (PRI) was developed as a multidimensional instrument to assess children's coping responses to recurrent pain. The PRI assesses 3 broad coping factors--Active, Passive, and Accommodative--each with subscales representing specific strategies for coping with pain. The PRI consists of 75 items assessing 15 potentially distinct coping strategies, each with a 5 item subscale.

The Questionnaire on Pediatric Gastrointestinal Symptoms (QPGS) assesses symptoms associated with FGIDs in children, as specified by the pediatric Rome criteria. This structured questionnaire includes sections assessing children's bowel habits, abdominal pain, and other gastrointestinal symptoms, as well as limitations in activities.

The Pain Beliefs Questionnaire is a 32-item measure assessing characteristic appraisals of pediatric abdominal pain severity (primary coping appraisals) and characteristic appraisals of ability to cope with pediatric abdominal pain (secondary coping appraisals). The questionnaire is available for both child and parent report. Respondents use a 0 (not at all true) to 4 (always true) rating scale.

The WL-SPT is a safe, non-invasive procedure that induces visceral discomfort in children for experimental purposes. The WL test requires the patient to drink water until "full." The visceral sensations it induces are associated with gastric distention and are similar to, but less intense than, those associated with naturally occurring episodes of abdominal pain experienced by children with recurrent abdominal pain.
