OBJECTIVES : We conducted a systematic review to determine the effectiveness of psychological interventions including psychodrama , cognitive behavioral therapy , relaxation therapy , guided imagery , or hypnosis in the improvement of  dyspepsia symptoms in patients with nonulcer dyspepsia ( NUD ) .
A randomized controlled trial of psychotherapy in patients with chronic functional dyspepsia.
BACKGROUND & AIMS This study aim ed to determine whether brief psychodynamic-interpersonal ( PI ) psychotherapy is more efficacious than a psychological control for patients with chronic , intractable functional dyspepsia ( FD ) , and whether patients with abnormal gastric function respond differently than those with normal gastric function . METHODS Ninety-five consecutive patients with chronic symptoms of FD who had failed to respond to conventional pharmacologic treatments were approached . Thirty-seven received  PI psychotherapy , and 36 the control condition ( supportive therapy ) . Patients completed self-report question naires before and after treatment and 12 months later . The patients ' gastroenterologists , who were blind to the study groups , conducted independent ratings before and after treatment . Forty-nine patients also underwent a radioisotope gastric emptying study . An intention-to-treat analysis was used with baseline scores as covariates . RESULTS At the end of treatment , there were significant advantages for PI psychotherapy compared with controls for the gastroenterologists ' ( P = 0.002 ) and patients ' total symptom score ( P = 0.015 ) . One year after treatment , the symptomatic scores were similar . However , a sub analysis showed that PI therapy was superior to the control condition at 1 year , when patients with severe heartburn were excluded . There was no difference in outcome between patients with normal and abnormal gastric emptying . CONCLUSIONS PI therapy may have both short- and long-term effects in patients with dyspepsia , but further evaluation is required . Its cost-effectiveness needs to be determined
