People with Somatic Symptom and related Disorders (SSD) have significantly lower psychological flexibility than those with central sensitivity syndromes (CSS) or controls. Low psychological flexibility in SSD is linked to poorer mental health, suggesting its importance in treatment.
Area of Science:
- Psychology
- Clinical Psychology
- Health Psychology
Background:
- Somatic Symptom and related Disorders (SSD) diagnosis involves significant distress and excessive focus on somatic symptoms.
- Central Sensitivity Syndromes (CSS), like fibromyalgia, lack this specific diagnostic emphasis.
- The emphasis on psychological processing in SSD suggests potentially low psychological flexibility.
Purpose of the Study:
- To investigate the levels of psychological flexibility in individuals with SSD.
- To compare psychological flexibility in SSD patients with CSS patients and healthy controls.
- To explore the association between psychological flexibility and mental health in SSD.
Main Methods:
- Cross-sectional study comparing psychological flexibility levels.
- Participants included 154 individuals with SSD, 597 with CSS, and 1422 controls.
- Statistical analyses adjusted for demographic covariates and examined associations with mental health.
Main Results:
- Mean psychological flexibility was lowest in SSD, intermediate in CSS, and highest in controls (p < 0.001).
- 74% of SSD patients exhibited low psychological flexibility, compared to 42% in CSS and 21% in controls.
- Higher psychological flexibility in SSD correlated with better mental health (β = 0.56, p < 0.001).
Conclusions:
- Lower psychological flexibility is a prevalent issue in Somatic Symptom and related Disorders.
- Psychological flexibility is significantly associated with mental health outcomes in SSD patients.
- Assessing and targeting psychological flexibility may be beneficial for SSD screening, monitoring, and therapy.
