Psychotherapy in functional dyspepsia.
Patients with functional dyspepsia were assigned at r and om to cognitive psychotherapy ( 10 sessions of 50 min duration , n = 50 ) or to a control group ( no treatment , n = 50 ) . Before treatment all patients were assessed on psychological , somatic and lifestyle factors . If allocated to the therapy group all patients were also asked to define the main problems they wanted to discuss in therapy ( ' target complaints ' ) . The patients were evaluated at the end of therapy ( after 4 months ) and at 1 yr follow-up . Outcome measures were dyspeptic symptoms , scores on ' target complaints ' and psychological parameters . Both groups showed improvement in dyspeptic and psychological parameters after 1 yr . The improvement in the control group was attributed to a non- specific effect of increased interest and attention . The therapy group showed greater reduction than the control group on dyspeptic symptoms [ days of epigastric pain ( p = 0.050 ) , nausea ( p = 0.024 ) , heartburn ( p = 0.021 ) , diarrhoea ( p = 0.002 ) and constipation ( p = 0.047 ) ] ; and on scores on ' target complaints ' ( p = 0.001 )
