Editor-In-Chief: C. Michael Gibson, M.S., M.D. ; Associate Editor(s)-in-Chief: Jesus Rosario Hernandez, M.D. 
Somatic symptom disorder is characterized by the presence of one or more somatic symptoms with excessive thoughts and behaviors associated with health concerns. 
- Anxiety disorder
- Body dysmorphic disorder
- Heart disease
- Irritable bowel syndrome
- Panic disorder
- Obsessive-compulsive disorder
Epidemiology and Demographics
The prevalence of somatic symptom disorder is 5,000 to 7,000 per 100,000 (5-7%) of the overall population.
- Negative affectivity (neuroticism)
- Comorbid anxiety
- Few years of education
- Lower socioeconomic status
- History of sexual abuse
Natural History, Complications and Prognosis
Poor prognostic factors include:
- Persistent depressive disorder (dysthymia)
- Panic disorder
- Social stress
- Illness benefits
DSM-V Diagnostic Criteria for Somatic Symptom Disorder
A. One or more somatic symptoms that are distressing or result in significant disruption of daily life.
B. Excessive thoughts, feelings, or behaviors related to the somatic symptoms or associated health concerns as manifested by at least one of the following:
- Disproportionate and persistent thoughts about the seriousness of one’s symptoms.
- Persistently high level of anxiety about health or symptoms.
- Excessive time and energy devoted to these symptoms or health concerns.
C. Although anyone somatic symptom may not be continuously present, the state of being symptomatic is persistent (typically more than 6 months).
- With predominant pain (previously pain disorder): This specifier is for individuals whose somatic symptoms predominantly involve pain.
- Persistent: A persistent course is characterized by severe symptoms, marked impairment, and long duration (more than 6 months).
Specify current severity:
- Mild: Only one of the symptoms specified in Criterion B is fulfilled.
- Moderate: Two or more of the symptoms specified in Criterion B are fulfilled.
- Severe: Two or more of the symptoms specified in Criterion B are fulfilled, plus there are multiple somatic complaints (or one very severe somatic symptom).
Most accurate diagnosis is be combining a somatic scale with a B symptoms scale, "Optimal combined cutpoints were ⩾9 for the PHQ-15 or SSS-8, and ⩾23 for the SSD-12 (sensitivity and specificity = 69% and 70%)".
Compared to the PHQ-15, the SSS-8 only has 8 questions, but the SSS-8 has 5 anchors for responses whereas the PHQ-15 is easier with only 3 anchors.
Area under the curve (AUC) 70
- Somatic Symptom Scale-8 (SSS-8).
Area under the curve (AUC) 70 For the SS-8, a score of:
- <= 6 makes somatic symptom disorder unlikely
- >= 19 makes somatic symptom disorder likely
The has been validated Somatic Symptom Disorder-B Criteria Scale (SSD-12).
Measurement-based care is guided by the somatic symptom scale-8. . A small randomized controlled trial  and a non-randomized study has addressed treatment.
Trials and reviews of cognitive behavioral therapy show benefit.
Short-term psychodynamic psychotherapy may help.
