Avoidant personality disorder and social phobia: Does mindreading make the difference?

Avoidant personality disorder (AvPD) is closely related to and partially overlaps with social phobia (SP). There is an ongoing debate as to whether AvPD and SP can be classified as separate and distinct disorders or whether these diagnoses rather reflect different degrees of severity of social anxiety. The hypothesis of this study is that in patients with AvPD and in those with AvPD and comorbid SP both interpersonal functioning and metacognitive abilities (the ability to understand mental states) are more severely impaired than they are in patients with SP only. We also hypothesise that the interpersonal and metacognitive functioning of these patients (both AvPD and AvPD+SP) is comparable to that of patients with other PD diagnoses. To test this hypothesis, we compared four groups (22 patients with SP, 32 patients with AvPD, 43 patients with both AvPD and SP and 50 patients with other personality disorders without SP and AvPD criteria) on metacognitive abilities, interpersonal functioning and global symptomatic distress. Metacognitive ability showed significant variation among the four groups, with the lowest score observed in the AvPD group. As far as the interpersonal functioning is concerned, the lack of sociability was more severe in the AvPD group compared with the SP group. These differences were maintained even after controlling for global symptomatic distress. Results are in line with the alternative model of PD, proposed in the DSM-5, as dysfunction of the self and relationships. They suggest that specific impairments in critical areas of self domains and interpersonal domains of personality functioning may serve as markers distinguishing AvPD from SP.

Attachment styles in patients with avoidant personality disorder compared with social phobia.

Avoidant personality disorder (AvPD) and social phobia (SP) are common, closely related conditions. Little is known about the underlying processes related to the social discomfort of subjects with AvPD and SP. Both disorders are associated with interpersonal problems. An attachment perspective may shed light on similarities and differences in close relationships between the disorders. The aim of the study was to compare self-reported attachment styles in patients with AvPD and SP. We expected that patients with AvPD would have more attachment anxiety and avoidance and more often a Fearful attachment style, compared with SP. This is a cross-sectional multisite study of 90 adult patients with AvPD and SP. Patients with AvPD with and without SP (AvPD group) were compared with patients with SP without AvPD (SP group). Patients were assessed using structured diagnostic interviews and self-reporting questionnaires, including Experiences in Close Relationships (ECR). The ECR dimensions, Anxiety and Avoidance, and the new described five factors of the ECR were used. The AvPD group had higher levels of attachment anxiety than the SP group, especially for the sub-factors Anxiety for abandonment and Separation frustration. The diagnostic groups did not differ in levels of avoidance. Anxiety for abandonment was still associated with AvPD after controlling for symptom disorders and the criteria of other personality disorders. A Fearful attachment style was more frequent among patients with AvPD. The results indicate AvPD is associated with more attachment anxiety than SP. Fear of abandonment may play a significant role in the AvPD pathology. This is the first study to compare attachment styles in patients with avoidant personality disorder (AvPD) and social phobia (SP). The AvPD group had higher attachment-related anxiety than the SP group, and anxiety was most pronounced for the fear of abandonment. Fear of abandonment may play an important role in the AvPD pathology.

Social anxiety disorder and avoidant personality disorder from an interpersonal perspective.

The general objective of this article is to study the unclear and overlapping relationship between social anxiety disorder (SAD) and avoidant personality disorder (AvPD) from an interpersonal perspective. The first specific objective is to compare the disorders with regard to interpersonal problems and general symptom distress. The second specific objective is to examine interpersonal subgroups and pathoplasticity. In a cross-sectional design, patients from an outpatient psychotherapy clinic diagnosed with social anxiety disorder (SAD, n = 299), avoidant personality disorder (AvPD, n = 180), or the comorbid condition of both disorders (AvPD + SAD, n = 29) were assessed before treatment. Patients filled out the Inventory of Interpersonal Problems (IIP-64) and the Symptom Checklist-Revised (SCL-R-90) before treatment. From an interpersonal perspective, the relationship between the diagnostic groups is well described by the severity continuum hypothesis, with similar interpersonal problems related to Nonassertiveness and lower levels of general interpersonal stress in the SAD group compared to the two AvPD groups. However, other differences in severity do not fit the severity continuum hypothesis, as there are no differences in severity on the global severity index, and, moreover, the SAD group has the most severe problems on the SCL-90 phobic anxiety scale. Interpersonal pathoplasticity is not found in the diagnostic groups or in the full sample. However, three interpersonal subgroups are identified in the full sample, designated as Nonassertive, Friendly-submissive, and Cold-submissive. Implications for treatment are discussed. SAD is characterized by a lower level of interpersonal distress compared to AvPD, but the two disorders are similar in having Nonassertiveness as their general interpersonal problem. Contrary to expectation, SAD and AvPD did not differ in general level of symptom severity, and patients with SAD reported more problems with phobic anxiety than AvPD patients did. When understanding SAD and AvPD as different conceptualizations of the same disorder and analysing all patients together, three distinct interpersonal subgroups emerge, which can be identified as Nonassertive, Friendly-submissive, and Cold-submissive.
