Secondly, sensory decision theory analysis was used to separate physiological from psychological components of perception: neurosensory sensitivity (p(A)) was measured by the ability to discriminate between 30 mm\u200aHg vs 34 mm\u200aHg distensions; psychological influences were measured by the report criterion\u2014that is, the overall tendency to report pain, indexed by the median intensity rating for all distensions, independent of intensity. Psychological symptoms were assessed using the Brief Symptom Inventory (BSI).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    IBS patients had lower AML pain thresholds (median: 28 mm\u200aHg vs 40 mm Hg; p&lt;0.001), but similar neurosensory sensitivity (median p(A): 0.5 vs 0.5; p\u200a=\u200a0.69; 42.6% vs 42.9% were able to discriminate between the stimuli better than chance) and a greater tendency to report pain (median report criterion: 4.0 (\u201cmild\u201d pain) vs 5.2 (\u201cweak\u201d pain); p\u200a=\u200a0.003). AML pain thresholds were not correlated with neurosensory sensitivity (r\u200a=\u200a\u22120.13; p\u200a=\u200a0.14), but were strongly correlated with report criterion (r\u200a=\u200a0.67; p&lt;0.0001). Report criterion was inversely correlated with BSI somatisation (r\u200a=\u200a\u22120.26; p\u200a=\u200a0.001) and BSI global score (r\u200a=\u200a\u22120.18; p\u200a=\u200a0.035).
