Abstract In the last few decades, there has been a long debate on the existence of agoraphobia (AG) without a history of panic attacks (PAs). In the present study, the problem of the relationships between AG and PAs is addressed trough a reevaluation of the cases who had been diagnosed with AG in the community survey of Sesto Fiorentino. Forty-one of the 75 subjects who met the criterion of AG in the Sesto Fiorentino Study were reinterviewed by experienced clinical psychiatrists. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition ( DSM-IV ) and the Composite International Diagnostic Interview were used to make the diagnoses. The Mobility Inventory for Agoraphobia (MIA) and a specific adjunctive question, “why do/did you avoid?,” were used to compare AG subjects with or without PD. Of the 41 subjects with a lifetime history of AG, 12 cases had original diagnosis of AG without PAs and the remaining 29 had PD with AG. After the reassessment, in 10 cases, the criteria for the diagnosis of AG without PAs were confirmed, totaling a lifetime prevalence of 0.4% (confidence interval, 0.2-0.8). Agoraphobia subjects with and without PAs were comparable as regard to sex, age, age of onset, duration of illness, family history for anxiety or mood disorders, MIA scores, number, and type of situations avoided. Thus, AG seems to exist also in absence of a history of PAs, and the one-way relationship between the occurrence of PAs and a following development of AG, postulated by DSM-IV , should be reconsidered for the future classifications.
