The characteristics of the comorbidity between social anxiety and separation anxiety disorders in adult patients.

Objective: In the present study, we compared social anxiety disorder (SAD) patients with (n = 31) and without childhood and adulthood separation anxiety disorder (SeAD) (n = 50) with respect to suicidal behavior, avoidant personality disorder (AvPD), other anxiety disorders (ADs), and major depression as well as some sociodemographic variables. Methods: In assessment of patients, we used Structured Clinical Interview for Separation Anxiety Symptoms, childhood and adulthood Separation Anxiety Symptom Inventories, Liebowitz Social Anxiety Scale, The SCID-II Avoidant Personality Disorder Module, Beck Depression Inventory, and Beck Scale for Suicidal Ideation. Results: SAD patients with SeAD had higher comorbidity rates of AvPD, other lifetime ADs and panic disorder, and current major depression than those without SeAD. The current scores of SAD, depression, and suicide ideation and the mean number of AvPD symptoms were significantly higher in comorbid group compared to pure SAD subjects. The SAD and SeAD scores had significant associations with current depression, suicide ideations, and AvPD. The mean number of AvPD criteria and the current severity of depression were significantly associated with the comorbidity between SAD and SeAD. Conclusion: Our findings might indicate that the comorbidity of SeAD with SAD may increase the risk of the severity of AvPD and current depression.

The importance of avoidant personality in social anxiety disorder with and without attention-deficit/hyperactivity disorder.

In the present study, our primary aim was to compare the generalized social anxiety (GSAD) patients with and without attention-deficit/hyperactivity disorder (ADHD) in terms of avoidant personality disorder (AVPD), and some clinical variables. We also investigated the relationship of AVPD and depression with ADHD and GSAD. We hypothesized that ADHD may be associated with AVPD in patients with GSAD. Seventy-six patients with GSAD were evaluated for depression, AVPD, and childhood and adulthood diagnoses of ADHD. The GSAD patients with (n = 34) and without adulthood ADHD (n = 30) were compared with respect to some sociodemographic and clinical variables. GSAD patients with adulthood ADHD had significantly higher comorbid diagnosis of AVPD, more avoidant personality and depression symptoms than those without ADHD. Pearson's correlation coefficient in total sample (n = 76) showed that the mean number of AVPD criteria was significantly associated with the severity of Beck Depression Inventory, Wender Utah Rating Scale (WURS), and inattention symptoms of ADHD. There were no correlations between the total and subscale scores of Liebowitz Social Anxiety Scale and the mean number of AVPD criteria. The scores of WURS significantly predicted the mean number of AVPD criteria (ß = 0.305, p= 0.007). The severity of current depression (ß = 0.143, p = 0.30) and inattention symptoms of adulthood ADHD (ß = 0.112, p = 0.46) were not associated with the severity of AVPD symptoms. These results might demonstrate that comorbid AVPD in adult SAD patients was related to a childhood ADHD independent from depression, and inattention symptoms of ADHD in adulthood.
