About this study

Official title: 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.

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Scores of Patient Health Questionnaire-15 (PHQ-15)

    Measurement of somatic distress. Score range is 0 to 30; higher score means more severe somatic distress

    Measured: Week 12 (comparing with the data in week 0)

  2. Scores of Health Anxiety Questionnaire (HAQ)

    Measurement of health anxiety. Score range is 0 to 63; higher score means more severe health anxiety

    Measured: Week 12 (comparing with the data in week 0)

Secondary outcomes (5)
  1. Scores of Beck Depression Inventory-II (BDI-II)

    Measurement of depression. Score range is 0 to 63; higher score means more severe depression

    Measured: Week 12 (comparing with the data in week 0)

  2. Scores of Beck Anxiety Inventory (BAI)

    Measurement of anxiety. Score range is 0 to 63; higher score means more severe anxiety

    Measured: Week 12 (comparing with the data in week 0)

  3. Scores of Cognitions About Body and Health Questionnaire (CABAH)

    Measurement of cognitions about health. Score range is 0 to 117; higher score means more severe cognitive distortion about health

    Measured: Week 12 (comparing with the data in week 0)

  4. Heart rate variability

    Measurement of parasympathetic activity

    Measured: Week 12 (comparing with the data in week 0)

  5. Skin conductance

    Measurement of sympathetic activity

    Measured: Week 12 (comparing with the data in week 0)
