Is there a correlation between somatic symptom disorder and a history of sexual trauma?

Correlation Between Somatic Symptom Disorder and History of Sexual Trauma

There is a significant association between somatic symptom disorder and history of sexual trauma, with research showing that individuals with a history of sexual abuse are 2-3 times more likely to develop somatic symptoms compared to those without such history.

Evidence for the Association

• Sexual abuse history is significantly associated with lifetime diagnosis of multiple somatic disorders, with meta-analysis data showing odds ratios ranging from 2.20 to 2.96 for various somatic conditions 1.

• When specifically examining cases where sexual abuse was defined as rape, the association becomes even stronger, with odds ratios increasing to 3.35-4.01 for conditions like fibromyalgia, chronic pelvic pain, and functional gastrointestinal disorders 1.

• Higher levels of lifetime adversity and trauma are significantly associated with more severe somatic symptoms (b = 6.95, p < .0001), with both posttraumatic stress symptoms and depressive symptoms serving as partial mediators of this relationship 2.

Gender Differences in Presentation

• Female trauma survivors develop somatic symptoms more frequently than males, with women reporting significantly more somatic symptoms overall 3.

• The pathways between trauma and somatic symptoms differ by gender:

  • For men, depression and substance abuse are associated with somatic symptom severity 3.
  • For women, depression is the primary pathway associated with somatic symptom severity 3.

• Women with a history of sexual violence and PTSD report higher levels of distress, fear, embarrassment, and pain during physical examinations compared to women without such history 4.

Clinical Manifestations

• Patients with somatic symptom disorder and a history of childhood sexual assault (which occurs in approximately 25.9% of patients with generalized anxiety disorder) may present with fewer somatic symptoms, specifically fewer motor tension and autonomic symptoms 5.

• Sexual trauma is associated with specific somatic presentations including:

  • Functional gastrointestinal disorders (OR 2.43) 1
  • Nonspecific chronic pain (OR 2.20) 1
  • Psychogenic seizures (OR 2.96) 1
  • Chronic pelvic pain (OR 2.73) 1

Treatment Considerations

• Despite the association between trauma history and somatic symptoms, trauma-focused treatments are effective and safe for patients with complex trauma histories 4.

• Evidence suggests that direct trauma-focused treatment is effective even for complex trauma, without requiring extensive stabilization phases before addressing the trauma directly 6.

• History of childhood sexual abuse does not appear to affect the severity of initial symptoms, symptom reduction rate, or number of sessions needed for effective trauma treatment 4.

Clinical Implications

• When evaluating patients with somatic symptom disorder, clinicians should consider screening for sexual trauma history, as this may be present in a substantial portion of these patients 1.

• Patients with somatic symptom disorder and sexual trauma history may experience more distress during physical examinations, particularly gynecological examinations for women 4.

• The presence of somatic symptoms can represent an important contextual factor in the determination or exacerbation of other conditions, including sexual dysfunction 7.

• Treatment approaches should address both the somatic symptoms and the underlying trauma, as evidence indicates that trauma-focused therapies are effective and do not lead to symptom exacerbation in this population 4, 6.
