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 ) .
Effects of treatment duration and severity of depression on the effectiveness of cognitive-behavioral and psychodynamic-interpersonal psychotherapy.
A total of 117 depressed clients , stratified for severity , completed 8 or 16 sessions of manualized treatment , either cognitive-behavioral psychotherapy ( CB ) or psychodynamic-interpersonal psychotherapy ( PI ) . Each of 5 clinician-investigators treated clients in all 4 treatment conditions . On most measures , CB and PI were equally effective , irrespective of the severity of depression or the duration of treatment . However , there was evidence of some advantage to CB on the Beck Depression Inventory ( Beck , Ward , Mendelson , Mock , & Erbaugh , 1961 ) . There was no evidence that CB 's effects were more rapid than those of PI , nor did the effects of each treatment method vary according to the severity of depression . There was no overall advantage to 16-session treatment over 8-session treatment . However , those presenting with relatively severe depression improved substantially more after 16 than after 8 sessions
