حملات هراس دستگاه گوارش متمرکز در میان پناهندگان کامبوجی: آسیب شناسی روانی مرتبط، فلش بک و شناخت فاجعه آمیز

Among Cambodian refugees attending a psychiatric clinic, we assessed psychopathology associated with gastrointestinal panic (GIP), and investigated possible causal mechanisms, including “fear of fear” and GIP-associated flashbacks and catastrophic cognitions. GIP (n = 46) patients had greater psychopathology (Clinician-Administered PTSD Scale [CAPS] and Symptom Checklist-90-R [SCL]) and “fear of fear” (Anxiety Sensitivity Index [ASI]) than did non-GIP patients (n = 84). Logistic regression revealed that general psychopathology (SCL; odds ratio = 4.1) and fear of anxiety-related sensations (ASI; odds ratio = 2.4) predicted the presence of GIP. Among GIP patients, a hierarchical regression revealed that GIP-associated trauma recall and catastrophic cognitions explained variance in GIP severity beyond a measure of general psychopathology (SCL). A mediational analysis indicated that SCL's effect on GIP severity was mediated by GIP-associated flashbacks and catastrophic cognitions.
