Afraid to go out: Poor quality of life with phobic anxiety in a large cross-sectional adult epilepsy center sample.

Purpose: People with epilepsy (PWE) have unmet healthcare needs, especially in the context of mental health. Although the current literature has established increased incidence of anxiety and depression in PWE and their contribution to poor quality of life, little is known regarding the presence and impact of specific phobia and agoraphobia. Our aim was to assess factors associated with high phobic/agoraphobic symptoms in a large, single tertiary epilepsy center sample, and to assess their impact on quality of life.

Methods: In a diverse sample of 420 adults with epilepsy, cross-sectional association of demographic, epilepsy and cognitive factors with high phobic symptoms were assessed using multiple logistic regression. Symptoms were measured with the SCL-90R validated self-report subscale (T-score ≥ 60 considered high phobic symptom group). Multiple logistic regression modeling was used to assess for independent association of demographic and clinical variables with presence of high phobic symptoms, and multiple linear regression modeling was used to evaluate for independent cross-sectional associations with epilepsy-specific quality of life (QOLIE-89).

Results: Lower education (adjusted OR 3.38), non-White race/ethnicity (adjusted OR 2.34), and generalized anxiety symptoms (adjusted OR 1.91) were independently associated with high phobic/agoraphobic symptoms, all p < 0.005. Phobic/agoraphobic symptoms were independently associated with poor quality of life as were depression symptoms, older age, and non-White race/ethnicity. Generalized anxiety did not demonstrate a significant independent association with quality of life in the multivariable model.

Conclusion: In this study sample, phobic/agoraphobic symptoms were independently associated with poor quality of life. Clinicians should consider using more global symptom screening instruments with particular attention to susceptible populations, as these impactful symptoms may be overlooked using generalized-anxiety focused screening paradigms.
