Cognitive modification versus prolonged exposure in vivo: a comparison with agoraphobics as subjects.

Cognitive restructuring and prolonged exposure in vivo were compared in a cross-over design with 21 agoraphobics.Assessments were made at the beginning of treatment, at cross-over, at the end of treatment and at the follow-up one month later. Assessment were carried out by an independent observer (phobic anxiety and avoidance scales and anxious mood) and by the client (measurement in vivo, phobic anxiety and avoidance scales. FSS, ASES, SDS and 1-E scale). Prolonged exposure in vivo proved to be a definitely superior form of treatment to cognitive restructuring, as measured by the behavioral in vivo measurement and the phobic anxiety and avoidance scales.
