Developing an Integrated Psychotherapy With Cognitive-behavioral Therapy and Biofeedback Therapy for Somatic Symptom Disorder: a Randomized Controlled Trial

This research program is aimed to develop a integrative psychotherapy (including CBT and biofeedback therapy) and to examine its efficacy on treatment of somatic symptom disorder. The study design is a randomized controlled trial with waiting list control. Scores of Patient Health Questionniare-15 and Health Anxiety Questionnaire are the primary endpoints.

Study Overview

Detailed Description

Somatic symptom disorder (SSD) is a psychiatric disorder featured with somatic distress and related psychological phenomena. In the past several years, our research team has investigated several aspects of SSD, including psychopathology, epidemiology, mechanism, and diagnostic biomarkers. But the aspect about treatment on SSD has not been comprehensively explored.

In literature, the treatment of SSD can be separated into physical and psychological approaches. The physical approach includes pharmacotherapy and magnetic/electrical neuromodulation. Among several types of psychotherapies, cognitive behavioral therapy (CBT) has the most evidence. Previous studies have disclosed SSD patients to have following cognitive or behavioral features: selective attention on somatic distress; memory bias on the severe health conditions; all-or-none cognition about health; organic attribution style; catastrophizing cognitive pattern about health; high motivation of concerning issues about health; inadequate reassurance-seeking behavior; the assumption about the connection between rest and somatic distress, etc.

Biofeedback therapy works by measuring several biological signals related with stress and relaxation (such as heart rate, skin conductance, electromyography, electroencephalography, and finger temperature); feedback of these signals to the subjects can help them more clearly understand the association between their behavior/cognition and relaxation. Biofeedback therapy has been extensively applied in the psychosomatic field.

This research program is aimed to develop a integrative psychotherapy (including CBT and biofeedback therapy) and to examine its efficacy. The study design is a randomized controlled trial with waiting list control. Scores of Patient Health Questionniare-15 (PHQ-15) and Health Anxiety Questionnaire (HAQ) are the primary endpoints; the changes of other psychological and biological measurements are viewed as secondary endpoints.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Experimental Group
The experimental group will receive cognitive-behavioral therapy (CBT) and biofeedback therapy.
Complete eight sessions of cognitive-behavioral therapy and biofeedback therapy within three months.
No Intervention: Control Group
The design of control group is waiting list control; their data will be collected without intervention during the observation period. After the observation period, psychotherapy (CBT and biofeedback, the same as intervention) will be arranged.
