Comparison of patterns and strength of adult attachment in patients with Axis I, Axis I+II disorders and a community sample

A cluster analysis of attachment styles in patients with borderline personality disorder, bipolar disorder and ADHD

BACKGROUND

Insecure adult attachment has been associated with psychiatric disorders characterized by emotional dysregulation, such as borderline personality disorder (BPD), bipolar disorder (BD) and attention deficit/hyperactivity disorder (ADHD). However, little is known about the differences in attachment patterns between these diagnostic groups. The aim of this study was to identify clusters of adult attachment style in a cross-diagnostic group of patients with BDP and/or BD and/or ADHD and explore the characteristics of these clusters based on temperament profile, childhood trauma and psychiatric diagnoses.

METHODS

K-means cluster analysis was used to identify subgroups, based on the Attachment Style Questionnaire Short Form dimensions, in a clinical cohort of 150 young adults (113 women and 37 men, mean age ± SD = 23.3 ± 2.1) diagnosed with BPD, and/or BD, and/or ADHD.

RESULTS

Three distinct clusters were identified: a secure, an insecure/avoidant-anxious and an insecure/avoidant cluster. These three clusters differed in temperament profile and related psychiatric diagnoses.

CONCLUSIONS

The three clusters of attachment in individuals with BPD, BD and/or ADHD could support differentiation between the disorders as well provide information usable for planning of treatment.

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

OBJECTIVES

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.

DESIGN

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).

METHODS

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.

RESULTS

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.

CONCLUSIONS

The results indicate AvPD is associated with more attachment anxiety than SP. Fear of abandonment may play a significant role in the AvPD pathology.

PRACTITIONER POINTS

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.

Experiences in Close Relationships – Psychometric properties among patients with personality disorders

Patients with personality disorders represent maladaptive attachment strategies, influencing the quality of their interpersonal relationships. Within these patient populations, it is important to have a measure, easily applied, to assess such strategies. A widely used instrument is Experiences in Close Relationships (ECR), assessing two constructs called avoidance and anxiety. Lately, two short forms of ECR have been proposed, called ECR-S and ECR-N12. The aim of this study is to investigate the psychometric properties of the Norwegian @version of ECR and its two short forms in a sample of patients with mainly personality disorders. An internal consistency and confirmatory factor analysis of ECR, ECR-S and ECR-N12 from 495 patients was conducted, as well as an exploratory factor analysis of ECR. The internal consistency of ECR was found questionable. Confirmatory factor analysis revealed a poor model fit based on ECR and ECR-S. The ECR-N12 revealed a mediocre fit, indicating a potential for improvement. Exploratory factor analysis indicated two different aspects of avoidance and three aspects of anxiety. This five-factor solution was called ECR-FF. Inferences from scores based on ECR should be derived with care. A revision of ECR and ECR-N12 is warranted, and further studies are needed to investigate the validity of ECR-FF.
