Unadjusted data was not statistically significant .
The other problems of psychological intervention included low recruitment and high drop out rate , which has been shown to be greater in patients receiving group therapy .
There is insufficient evidence from this review to confirm the efficacy of psychological intervention in NUD
BACKGROUND Studies have also shown that non-ulcer dyspepsia ( NUD ) patients have higher scores of anxiety , depression , neurotism , chronic tension , hostility , hypochondriasis and tendency to be more pessimistic when compared with the community controls .
However , the role of psychological interventions in NUD remains uncertain .
OBJECTIVES This review aims to determine the effectiveness of psychological interventions including psychotherapy , psychodrama , cognitive behavioural therapy , relaxation therapy and hypnosis in the improvement of either individual or global dyspepsia symptom scores and quality of life scores in patients with NUD .
A controlled trial of psychological treatment for the irritable bowel syndrome.
One hundred two patients with irritable bowel syndrome were studied in a controlled trial of psychological treatment involving psychotherapy , relaxation , and st and ard medical treatment compared with st and ard medical treatment alone .  Patients were only selected if their symptoms had not improved with st and ard medical treatment over the previous 6 months . At 3 months , the treatment group showed significantly greater improvement than the controls on both gastroenterologists ' and patients ' ratings of diarrhea and abdominal pain , but constipation changed little . Good prognostic factors included overt psychiatric symptoms and intermittent pain exacerbated by stress , whereas those with constant abdominal pain were helped little by this treatment . This study has demonstrated that psychological treatment is feasible and effective in two thirds of those patients with irritable bowel syndrome who do not respond to st and ard medical treatment
