Avoidant personality disorder: current status and future directions

Toward a More Nuanced Perspective on Detachment: Differentiating Schizoid and Avoidant Personality Styles through Qualities of the Self-Representation

Avoidant personality disorder was introduced in DSM-III (American Psychiatric Association [APA], 1980), and debate persists regarding the utility of having two separate variants of the "detached personality." The present study addressed this issue through ratings of open-ended self-descriptions provided by community adults with high scores on schizoid versus avoidant personality traits (N = 229). The self-concept of individuals with avoidant personality style reflected a lack of positive self-regard and low self-efficacy/agency. Regarding schizoid personalities, neither positive nor negative self-regard, self-complexity, or self-efficacy/agency was found. Examination of specific variables yielded a relationship between avoidant personality styles, depression, and anxiety, consistent with literature noting simultaneous desire and fear of interpersonal relationships in avoidant patients (APA, 1980; Sheldon & West, 1990). Similarly, examination of individual variables yielded a negative association between schizoid personality styles and tolerance for contradictory aspects of the self, consistent with theoretical writings in this area (Kernberg, 1976; McWilliams, 2006). Results support the argument that these two personality styles represent distinct constructs. Findings support the utility of self-concept assessment to assist treatment planning and differential diagnosis. Treatment implications include using open-ended descriptions of patients' self-concepts to explore changes that may not be accessible via more structured forms of patient self-report.

Neurogenetics and Epigenetics of Loneliness

Loneliness, an established risk factor for both, mental and physical morbidity, is a mounting public health concern. However, the neurobiological mechanisms underlying loneliness-related morbidity are not yet well defined. Here we examined the role of genes and associated DNA risk polymorphic variants that are implicated in loneliness via genetic and epigenetic mechanisms and may thus point to specific therapeutic targets. Searches were conducted on PubMed, Medline, and EMBASE databases using specific Medical Subject Headings terms such as loneliness and genes, neuro- and epigenetics, addiction, affective disorders, alcohol, anti-reward, anxiety, depression, dopamine, cancer, cardiovascular, cognitive, hypodopaminergia, medical, motivation, (neuro)psychopathology, social isolation, and reward deficiency. The narrative literature review yielded recursive collections of scientific and clinical evidence, which were subsequently condensed and summarized in the following key areas: (1) Genetic Antecedents: Exploration of multiple genes mediating reward, stress, immunity and other important vital functions; (2) Genes and Mental Health: Examination of genes linked to personality traits and mental illnesses providing insights into the intricate network of interaction converging on the experience of loneliness; (3) Epigenetic Effects: Inquiry into instances of loneliness and social isolation that are driven by epigenetic methylations associated with negative childhood experiences; and (4) Neural Correlates: Analysis of loneliness-related affective states and cognitions with a focus on hypodopaminergic reward deficiency arising in the context of early life stress, eg, maternal separation, underscoring the importance of parental support early in life. Identification of the individual contributions by various (epi)genetic factors presents opportunities for the creation of innovative preventive, diagnostic, and therapeutic approaches for individuals who cope with persistent feelings of loneliness. The clinical facets and therapeutic prospects associated with the current understanding of loneliness, are discussed emphasizing the relevance of genes and DNA risk polymorphic variants in the context of loneliness-related morbidity.

Comparison of Cognitive Behavioral Therapy and Cognitive Behavioral Group Therapy in the Treatment of Avoidant Personality Disorder

The primary aim of this study is to compile studies on cognitive behavioral therapy method in the treatment of avoidant personality disorder and present their data. Another aim is to discuss with the reasons, cognitive behavior group therapies may be more effective on this disorder than cognitive behavioral individual therapies, since the main problem in avoidant personality disorder stems from interpersonal communication and because the cognitive behavioral therapies applied as a group were found to be quite effective when the avoidant personality disorder was first defined. The aim of this study is to present recommendations together and to compile studies in which cognitive behavioral group therapies were applied on avoidant personality disorder. In this study, studies in domestic and foreign sources, which were conducted with a sample group with avoidant personality disorder and social anxiety disorder, were examined and the study was prepared by reviewing the literature, which is one of the secondary data collection techniques. Since there are not many studies on avoidant personality disorder in the literature, considering the high similarity and comorbidity of avoidant personality disorder with social anxiety disorder, studies on cognitive behavioral group therapies related to social anxiety disorder have also been compiled. As a result of the studies examined, it has been found that the symptoms of avoidant personality disorder are related to the distorted cognition of individuals and cognitive behavioral therapies are a very effective approach because they increase the awareness of the automatic thoughts in the minds of the clients, question their correctness and provide alternative thoughts to replace them.

The role of adverse childhood experiences and attachment styles in social anxiety disorder in adolescents

BACKGROUND

Social Anxiety Disorder (SAD) is one of the most common disorders of adolescence and results in marked impairments in social and academic/occupational activities that likely to persist into adulthood. Multiple etiological factors contribute to the development of social anxiety disorder. Two critical factors in presenting with a primary diagnosis of SAD might be adverse childhood experiences (ACEs) and attachment styles. The current study examined how ACEs and attachment styles may be related to SAD in adolescents.

METHODS

60 participants with ages ranging from 11 to 18 (M = 14.6; female = 36), who have a primary diagnosis of SAD and 60 control group adolescents (M = 14.6; female = 30) were included in the study. Both groups completed the Liebowitz Social Anxiety Scale (LSAS), the Childhood Trauma Questionnaire (CTQ), and the Adolescent Relationship Scales Questionnaire (A-RSQ).

RESULTS

After controlling adolescent gender and parental education levels, childhood emotional neglect and income significantly predicted an increased risk for adolescents' SAD diagnosis. Attachment styles did not significantly contribute to predicting adolescents' SAD diagnosis after controlling childhood emotional neglect.

CONCLUSION

The high predictive value of emotional neglect in childhood emphasizes its importance as a risk factor of SAD in adolescence.

Clinical Efficacy and Cost-Effectiveness of Imagery Rescripting Only Compared to Imagery Rescripting and Schema Therapy in Adult Patients With PTSD and Comorbid Cluster C Personality Disorder: Study Design of a Randomized Controlled Trial

Background: Posttraumatic stress disorder (PTSD) is a serious and relatively common mental disorder causing a high burden of suffering. Whereas evidence-based treatments are available, dropout and non-response rates remain high. PTSD and Cluster C personality disorders (avoidant, dependent or obsessive-compulsive personality disorder; CPD) are highly comorbid and there is evidence for suboptimal treatment effects in this subgroup of patients. An integrated PTSD and CPD treatment may be needed to increase treatment efficacy. However, no studies directly comparing the efficacy of regular PTSD treatment and treatment tailored to PTSD and comorbid CPD are available. Whether integrated treatment is more effective than treatment focused on PTSD alone is important, since (1) no evidence-based guideline for PTSD and comorbid CPD treatment exists, and (2) treatment approaches to CPD are costly and time consuming. Present study design describes a randomized controlled trial (RCT) directly comparing trauma focused treatment with integrated trauma focused and personality focused treatment. Methods: An RCT with two parallel groups design will be used to compare the clinical efficacy and cost-effectiveness of "standalone" imagery rescripting (n = 63) with integrated imagery rescripting and schema therapy (n = 63). This trial is part of a larger research project on PTSD and personality disorders. Predictors, mediators and outcome variables are measured at regular intervals over the course of 18 months. The main outcome is PTSD severity at 12 months. Additionally, machine-learning techniques will be used to predict treatment outcome using biopsychosocial variables. Discussion: This study protocol outlines the first RCT aimed at directly comparing the clinical efficacy and cost-effectiveness of imagery rescripting and integrated imagery rescripting and schema therapy for treatment seeking adult patients with PTSD and comorbid cluster C personality pathology. Additionally, biopsychosocial variables will be used to predict treatment outcome. As such, the trial adds to the development of an empirically informed and individualized treatment indication process. Clinical Trial registration: ClinicalTrials.gov, NCT03833531.

DSM‐IV personality disorders and the Five‐Factor Model of personality: a multi‐method examination of domain‐ and facet‐level predictions

The personality disorder classification system (Axis II) in the various versions of the Diagnostic and Statistical Manuals of Mental Disorders (DSM) has been the target of repeated criticism, with conceptual analysis and empirical evidence documenting its flaws. In response, many have proposed alternative approaches for the assessment of personality psychopathology, including the application of the Five‐Factor Model of personality (FFM). Many remain sceptical, however, as to whether domain and facet traits from a model of general personality functioning can be successfully applied to clinical patients with personality disorders (PDs). In this study, with a sample of psychiatric patients (n = 115), personality disorder symptoms corresponding to each of the 10 PDs were successfully predicted by the facet and domain traits of the FFM, as measured by a semi‐structured interview, the Structured Interview for the Five Factor Model (SIFFM; Trull & Widiger, 1997) and a self‐report questionnaire, the Revised NEO Personality Inventory (NEO PI‐R; Costa and McCrae, 1992). These results provide support for the perspective that personality psychopathology can be captured by general personality dimensions. The FFM has the potential to provide a valid and scientifically sound framework from which to assess personality psychopathology, in a way that covers most of the domains conceptualized in DSM while transcending the limitations of the current categorical approach to these disorders.

Social anxiety disorder and avoidant personality disorder from an interpersonal perspective

OBJECTIVES

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.

DESIGN

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.

METHODS

Patients filled out the Inventory of Interpersonal Problems (IIP-64) and the Symptom Checklist-Revised (SCL-R-90) before treatment.

RESULTS AND CONCLUSIONS

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.

PRACTITIONER POINTS

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.

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 (β = 0.305, p= 0.007). The severity of current depression (β = 0.143, p = 0.30) and inattention symptoms of adulthood ADHD (β = 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.

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.

Relationships Among Avoidant Personality Disorder, Social Anxiety Disorder, and Normative Personality Traits: A Twin Study

Avoidant personality disorder (AvPD) and social anxiety disorder (SAD) share risk factors to a substantial degree, and both are characterized by the experience of anxiety in social situations. The authors investigated whether these disorders are differentially related to the Big Five personality traits. They also examined the underlying genetic and environmental influences on these associations. A population-based sample of 1,761 female twins was interviewed at baseline, and 1,471 of these were re-interviewed 10 years later. Associations between AvPD, SAD, and personality traits were investigated with multivariate biometric analyses. The authors found that AvPD and SAD are differentially related to several personality traits at the phenotypic, genetic, and environmental level. The genetic and environmental liability to AvPD could be fully accounted for by the genetic and environmental factors influencing SAD and personality. The findings may increase current etiological understanding of these disorders and inform future classification and treatment efforts.

Avoidant personality disorder: current insights

Avoidant personality disorder (AVPD) is a relatively common disorder that is associated with significant distress, impairment, and disability. It is a chronic disorder with an early age at onset and a lifelong impact. Yet it is underrecognized and poorly studied. Little is known regarding the most effective treatment. The impetus for research into this condition has waxed and waned, possibly due to concerns regarding its distinctiveness from other disorders, especially social anxiety disorder (SAD), schizoid personality disorder, and dependent personality disorder. The prevailing paradigm subscribes to the "severity continuum hypothesis", in which AVPD is viewed essentially as a severe variant of SAD. However, areas of discontinuity have been described, and there is support for retaining AVPD as a distinct diagnostic category. Recent research has focused on the phenomenology of AVPD, factors of possible etiological significance such as early parenting experiences, attachment style, temperament, and cognitive processing. Self-concept, avoidant behavior, early attachments, and attachment style may represent points of difference from SAD that also have relevance to treatment. Additional areas of research not focused specifically on AVPD, including the literature on social cognition as it relates to attachment and personality style, report findings that are promising for future research aimed at better delineating AVPD and informing treatment.

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

OBJECTIVE

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.

METHODS

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.

RESULTS

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.

CONCLUSION

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.

Stability or instability in avoidant personality disorder:Mode fluctuations within schema therapy sessions

BACKGROUND AND OBJECTIVES

Avoidant personality disorder (APD) is among the most prevalent personality disorders, but has received relatively little empirical attention. This study aims to characterize the frequency, intensity, and fluctuation patterns seen in the modes (self-states) of APD clients over the course of schema therapy (ST), a psychotherapy approach developed especially for personality disorders.

METHOD

The newly-developed client mode rating scale (CMRS) was used to code every 5-min segment (n = 645) of 60 ST sessions. Each segment was coded by two independent raters, achieving adequate reliability.

RESULTS

The avoidant/detached mode was present in 74% of therapy segments and was the most intense and unstable mode; the vulnerable child mode was present in 58% of segments and was the second most intense and unstable mode; the dysfunctional parent mode was present in 40% of segments, and was the third most intense and unstable mode; the over-compensator, compliant-surrenderer, and healthy adult modes were present in around 33% of segments, but the healthy adult mode was significantly more stable than all others.

LIMITATIONS

Although 645 segments were coded, they were drawn from only 15 APD clients with no control group. Further studies are needed to established specificity to APD.

CONCLUSIONS

This study demonstrates the utility of the mode concept as a lexicon for capturing personality states and their instability. It highlights the use of in-session segment-by-segment ratings to assess client change within psychotherapy. Although DSM5 fails to address instability as a criterion for avoidant personality disorder, the APD clients in the current study were characterized by considerable mode instability.

Genetic and Neuroimaging Features of Personality Disorders: State of the Art

Personality disorders often act as a common denominator for many psychiatric problems, and studies on personality disorders contribute to the etiopathology, diagnosis, and treatment of many mental disorders. In recent years, increasing evidence from various studies has shown distinctive features of personality disorders, and that from genetic and neuroimaging studies has been especially valuable. Genetic studies primarily target the genes encoding neurotransmitters and enzymes in the serotoninergic and dopaminergic systems, and neuroimaging studies mainly focus on the frontal and temporal lobes as well as the limbic-paralimbic system in patients with personality disorders. Although some studies have suffered due to unclear diagnoses of personality disorders and some have included few patients for a given personality disorder, great opportunities remain for investigators to launch new ideas and technologies in the field.

Avoidant Personality Disorder: a Current Review

This review focuses on recent research on diagnostic aspects, etiology, and treatment of avoidant personality disorder (AVPD). Current studies stress the close relation between AVPD and social anxiety disorder, the influence of genetic factors in the development of AVPD, and the relative stability of symptoms. Treatment approaches should target the pervasive patterns of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. Empirical evidence for cognitive-behavior and schema therapy is promising. Few other therapeutic approaches have been developed, but until now, these have only been investigated in case studies. We conclude that AVPD qualifies as a neglected disorder and that more research specifically on avoidant personality disorder symptoms and its treatment is needed.

Longitudinal associations between social anxiety disorder and avoidant personality disorder: A twin study

Social anxiety disorder (SAD) and avoidant personality disorder (AvPD) are frequently co-occurring psychiatric disorders with symptomatology related to fear of social situations. It is uncertain to what degree the 2 disorders reflect the same genetic and environmental risk factors. The current study addresses the stability and co-occurrence of SAD and AvPD, the factor structure of the diagnostic criteria, and genetic and environmental factors underlying the disorders at 2 time points. SAD and AvPD were assessed in 1,761 young adult female twins at baseline and 1,471 of these approximately 10 years later. Biometric models were fitted to dimensional representations of SAD and AvPD. SAD and AvPD were moderately and approximately equally stable from young to middle adulthood, with increasing co-occurrence driven by environmental factors. At the first wave, approximately 1 in 3 individuals with AvPD had SAD, increasing to 1 in 2 at follow-up. The diagnostic criteria for SAD and AvPD had a two-factor structure with low cross-loadings. The relationship between SAD and AvPD was best accounted for by a model with separate, although highly correlated (r = .76), and highly heritable (.66 and .71) risk factors for each disorder. Their genetic and environmental components correlated .84 and .59, respectively. The finding of partially distinct risk factors indicates qualitative differences in the etiology of SAD and AvPD. Genetic factors represented the strongest time-invariant influences, whereas environmental factors were most important at the specific points in time.

Correlates of interpersonal dependency and detachment in an adolescent inpatient sample

Interpersonal dependency has been linked to psychological distress, depression, help seeking, treatment compliance, and sensitivity to interpersonal cues in adult samples. However, there is a dearth of research focusing on dependency in child and adolescent samples. The current study examined the construct validity of a measure of interpersonal dependency. The authors investigated how interpersonal dependency and detachment relate to behavioral problems, subjective well-being, interpersonal problems, and global symptom severity in adolescent inpatients. Destructive overdependence (DO) and dysfunctional detachment (DD) were positively related to interpersonal distress, behavioral problems, and symptom severity and negatively related to psychological health and well-being. Healthy dependency (HD) was associated with fewer behavioral problems and less symptom severity and positively related to subjective well-being. The clinical implications of these findings are discussed.

Beyond Description in Interpersonal Construct Validation: Methodological Advances in the Circumplex Structural Summary Approach

The interpersonal circumplex is a well-established structural model that organizes interpersonal functioning within the two-dimensional space marked by dominance and affiliation. The structural summary method (SSM) was developed to evaluate the interpersonal nature of other constructs and measures outside the interpersonal circumplex. To date, this method has been primarily descriptive, providing no way to draw inferences when comparing SSM parameters across constructs or groups. We describe a newly developed resampling-based method for deriving confidence intervals, which allows for SSM parameter comparisons. In a series of five studies, we evaluated the accuracy of the approach across a wide range of possible sample sizes and parameter values, and demonstrated its utility for posing theoretical questions on the interpersonal nature of relevant constructs (e.g., personality disorders) using real-world data. As a result, the SSM is strengthened for its intended purpose of construct evaluation and theory building.

Avoidant personality disorder versus social phobia: the significance of childhood neglect

OBJECTIVES

Avoidant personality disorder (AvPD) and social phobia (SP) are common disorders both in the community and in clinical settings. Whether the two disorders represent different severity levels of social anxiety disorder is currently in dispute. The relationship between AvPD and SP is probably more complex than previously assumed. Several environmental, temperamental, and constitutional factors may play a role in the etiology of AvPD and SP. Better knowledge about childhood experiences may shed light on similarities and differences between the two disorders. The aim of this study was to compare self-reported childhood experiences in AvPD and SP patients.

DESIGN

This is a cross-sectional multi-site study of 91 adult patients with AvPD and/ or SP. We compared patients with AvPD with and without SP (AvPD group) to patients with SP without AvPD (SP group).

METHODS

The patients were examined using structured diagnostic interviews and self-report measures, including Child Trauma Questionnaire, Parental Bonding Instrument, and Adult Temperament Questionnaire.

RESULTS

Both AvPD and SP were associated with negative childhood experiences. AvPD patients reported more severe childhood neglect than patients with SP, most pronounced for physical neglect. The difference between the disorders in neglect remained significant after controlling for temperamental factors and concurrent abuse.

CONCLUSIONS

The study indicates that childhood neglect is a risk factor for AvPD and may be one contributing factor to phenomenological differences between AvPD and SP.

Social phobia and avoidant personality disorder: similar but different?

Avoidant personality disorder (AvPD) is regarded as a severe variant of social phobia (SP), consistent with a dimensional model. However, these conclusions are largely drawn from studies based on individuals with SP, with or without comorbid AvPD. The present study hypothesized that there are qualitative differences between AvPD and SP that are undermined by limiting research to participants with SP. The authors sought to test this hypothesis by comparing three groups-SP only, AvPD only, and SP+AvPD-using data extracted from an epidemiological sample of 10,641 adults aged 18 years and over. Screening questions were used in the epidemiological survey to identify ICD-10 personality disorders; from this the author developed a proxy measure for DSM-IV AvPD. Axis I diagnoses, including DSM-IV SP, were identified using the Composite International Diagnostic Interview (CIDI). In this sample, the majority of those with AvPD did not also have SP: The authors found 116 persons with AvPD only, 196 with SP only, and 69 with SP+AvPD. There was little difference between any of the groups on sex, marital status, employment, education, or impairment variables. The SP+AvPD group reported more distress and comorbidity than the SP only and AvPD only groups, which did not differentiate from each other. More feared social situations were endorsed in the SP only group compared to the AvPD only group. Although the finding of few differences between SP only and AvPD only groups among the variables measured in this epidemiological survey fails to provide support for the hypothesis of qualitative differences, the finding that the AvPD only group appears more similar to the SP only group than to the SP+AvPD group also fails to provide support for the alternative continuity hypothesis. The greater distress and additional comorbidity with depression associated with SP+AvPD may be due to the additional symptom load of a second disorder rather than simply representing a more severe variant of social phobia. The use of a proxy for AvPD is a limitation of the study. Future studies should focus on broader clinical variables that have been proposed as qualitatively different between these disorders, and on the possible genetic and environmental factors that might help explain such differences.

The association between interpersonal problems and treatment outcome in the eating disorders: A systematic review

OBJECTIVE

To review systematically the eating disorder literature in order to examine the association between pre-treatment interpersonal problems and treatment outcome in people diagnosed with an eating disorder.

METHODS

Six relevant databases were searched for studies in which interpersonal problems prior to treatment were examined in relation to treatment outcome in patients diagnosed with anorexia nervosa (AN), bulimia nervosa (BN) or eating disorders not otherwise specified (EDNOS).

RESULTS

Thirteen studies were identified (containing 764 AN, 707 BN and 48 EDNOS). The majority of studies indicated that interpersonal problems at the start of therapy were associated with a detrimental treatment outcome.

CONCLUSIONS

Individuals with a binge/purge-type of eating disorder may be particularly vulnerable to interpersonal issues and these issues may lead to poorer treatment recovery by reducing the individual's ability to engage in the treatment process on a functional level. The clinical and research implications are discussed.

On the structure of personality disorder traits: conjoint analyses of the CAT-PD, PID-5, and NEO-PI-3 trait models

The current study examines the relations among contemporary models of pathological and normal range personality traits. Specifically, we report on (a) conjoint exploratory factor analyses of the Computerized Adaptive Test of Personality Disorder static form (CAT-PD-SF) with the Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders, fifth edition and NEO Personality Inventory-3 First Half, and (b) unfolding hierarchical analyses of the three measures in a large general psychiatric outpatient sample (n = 628; 64% Female). A five-factor solution provided conceptually coherent alignment among the CAT-PD-SF, PID-5, and NEO-PI-3FH scales. Hierarchical solutions suggested that higher-order factors bear strong resemblance to dimensions that emerge from structural models of psychopathology (e.g., Internalizing and Externalizing spectra). These results demonstrate that the CAT-PD-SF adheres to the consensual structure of broad trait domains at the five-factor level. Additionally, patterns of scale loadings further inform questions of structure and bipolarity of facet and domain level constructs. Finally, hierarchical analyses strengthen the argument for using broad dimensions that span normative and pathological functioning to scaffold a quantitatively derived phenotypic structure of psychopathology to orient future research on explanatory, etiological, and maintenance mechanisms.

Toward a firmer foundation for DSM-5.1: domains of impairment in DSM-IV/DSM-5 personality disorders

In recent editions of the Diagnostic and Statistical Manual of Mental Disorders, personality disorders (PDs) have been conceptualized as reflecting impairments in four areas: cognition, affectivity, interpersonal functioning, and impulse control. However, there have been no systematic surveys of PD symptoms to assess the degree to which these four domains of impairment are actually represented in the DSM-IV/DSM-5 PD symptom criteria. Results of such a survey indicated that the most common domain of impairment for DSM-IV/DSM-5 PDs is interpersonal functioning (41% of all PD symptoms), followed by cognition (30%), and affectivity (18%), with relatively few PD symptoms reflecting difficulties in impulse control (6%). Comparison of the proportions of symptoms in different impairment domains in DSM-III, DSM-III-R, and DSM-IV/DSM-5 confirmed that these symptom distributions have been stable across revisions of the diagnostic manual. Implications of these results for the conceptualization of PDs in DSM-5.1 and beyond are discussed.

Personality functioning in patients with avoidant personality disorder and social phobia

Avoidant personality disorder (APD) and social phobia (SP) are closely related, such that they are suggested to represent different severity levels of one social anxiety disorder. This cross-sectional study aimed to compare patients with APD to patients with SP, with particular focus on personality dysfunction. Ninety-one adult patients were examined by diagnostic interviews and self-report measures, including the Index of Self-Esteem and the Severity Indices of Personality Problems. Patients were categorized in three groups; SP without APD (n = 20), APD without SP (n = 15), and APD with SP (n = 56). Compared to patients with SP without APD, patients with APD reported more symptom disorders, psychosocial problems, criteria of personality disorders, and personality dysfunction regarding self-esteem, identity and relational problems. These results indicate that APD involves more severe and broader areas of personality dysfunction than SP, supporting the conceptualization of APD as a personality disorder as proposed for DSM-5.

Self-esteem and other-esteem in college students with borderline and avoidant personality disorder features: An experimental vignette study

An experimental study investigated self-esteem and other-esteem responses to either fully supportive or less supportive interpersonal feedback in college students with avoidant and borderline personality disorder features (APD and BPD respectively). Disturbances in self-esteem and in evaluations of others are central to definitions of both APD and BPD, but the extent to which such interpersonal appraisals are responsive to contextual features, such as evaluative feedback from others, is not yet clear. In theory, we would expect that individuals with pronounced PD features would show more inflexible and more negative self-evaluations and others- evaluations than those without PD features. In this study with 169 undergraduates, APD but not BPD features were associated with other-contingent state self-esteem and other-esteem. A significant interaction indicated that highly avoidant respondents felt particularly negatively about themselves and their close others in situations that conveyed subtle criticism but not in situations signalling unequivocal support. This suggests that their self-esteem and other-esteem, rather than being rigidly negative, are instead highly contingent upon interpersonal feedback. Such context contingency has implications for the trait-like description of diagnostic characteristics within current taxonomies and is in line with contemporary dynamic models of personality structure and process.

Homicidal behaviour among people with avoidant, dependent and obsessive-compulsive (cluster C) personality disorder

BACKGROUND

Despite a growing forensic psychiatry literature, no previous study has examined in detail homicidal behaviour among offenders with cluster C personality disorders - the avoidant, dependent or obsessional personality disorders.

AIMS

This study aims to compare homicide offenders with cluster C personality disorders with those with other personality disorders on criminal history, offender-victim relationship and post-offence reaction variables.

METHODS

The sample was drawn from all Finnish homicide cases of 1996-2004 for whom a forensic psychiatric evaluation had been conducted. Data were extracted from forensic psychiatric and crime reports.

RESULTS

In a nationwide sample of 593 homicide offenders, 21 had at least one cluster C personality disorder. These offenders had significantly shorter criminal histories than the others. Offender-victim relationship did not differ between the groups, but confession to the crime and feelings of remorse were more common among people with cluster C disorders. In addition, compared with other personality disorder clusters, co-morbid depression was more common.

CONCLUSIONS

Cluster C personality disorders are rare, but not nonexistent, among homicide offenders. Observed differences in their backgrounds and post-offence behaviours indicate that they may have special needs.

Interpersonal Psychotherapy Informed Treatment for Avoidant Personality Disorder With Subsequent Depression

This is a single-case study of a young woman with avoidant personality disorder (APD) and subsequent depression, worry, lack of motivation, feelings of inadequacy, and nonassertive behaviors in her romantic relationship and professional career. Treatment was informed by interpersonal psychotherapy (IPT) for depression and also utilized assertiveness skills training. The client’s self-confidence was tracked daily, using a subjective self-report measure, and the completion of personality and symptom assessment measures before treatment (Phase A) and during the termination stage of treatment. Simulation Modeling Analysis for Time Series evaluated the change in levels of self-confidence across baseline, active treatment (Phase B), and termination (Phase C). In addition, reliable change was assessed using a comparison of Minnesota Multiphasic Personality Inventory 2–Restructured Form and Symptom Checklist-90–Revised results from baseline and Phase C. The patient experienced symptom improvement in self-confidence, somatic complaints, stress and worry, anxiety, and depression, suggesting that IPT techniques may be useful in the treatment of APD.

Avoidant personality problems--their association with somatic and mental health, lifestyle, and social network. A community-based study

AIM

The aim of the study was to explore the associations between the presence of avoidant personality problems (APPs) and 5 areas of impairment: demography, somatic issues, mental health, lifestyle, and social issues.

METHODS

Avoidant personality problem was defined by confirmation of the 2 avoidant personality disorder items of the Iowa Personality Disorder Screen and and the Social Phobia Inventory (SPIN) short version (MINI-SPIN) screening assessment for generalized social anxiety disorder sum score of 6 or more. The questionnaires were administered in a Norwegian population survey (the Oslo Health Study-HUBRO). Cases consisted of 280 individuals with APP and 5 randomly selected controls without APP (n = 1400).

RESULTS

The APP group more frequently reported living alone, lower level of education, and lower income than controls. Poor self-rated health, presence of somatic disease, muscular pain, frequent use of analgesics, and visits at a general practitioner were significantly more common in the APP group than among controls. The APP group had significantly higher proportion of caseness of mental distress, low general self-efficacy, and insomnia, and this result held up in multivariate analyses. The APP group showed statistically significant higher proportions of physical inactivity, obesity, daily smoking, and alcohol problems compared with controls. As for social impairment, a significantly higher proportion of the APP group reported "not having enough good friends," "high powerlessness," and low community activism, and the 2 former variables held up in multivariate analyses.

CONCLUSION

In this population-based study, we found that high levels of APP, defined closely to avoidant personality disorder, were significantly associated with demographic, somatic, and mental impairment; low general self-efficacy; and insomnia affecting work ability. In addition, APP showed associations with negative lifestyle, alcohol problems, and social impairment reporting lack of good friends and lack of empowerment. Avoidant personality problem is associated with clinically significant impairment in several areas, which underlines the importance of recognizing these problems in primary health care.

A parallel process growth model of avoidant personality disorder symptoms and personality traits

Avoidant personality disorder (AVPD), like other personality disorders, has historically been construed as a highly stable disorder. However, results from a number of longitudinal studies have found that the symptoms of AVPD demonstrate marked change over time. Little is known about which other psychological systems are related to this change. Although cross-sectional research suggests a strong relationship between AVPD and personality traits, no work has examined the relationship of their change trajectories. The current study sought to establish the longitudinal relationship between AVPD and basic personality traits using parallel process growth curve modeling. Parallel process growth curve modeling was applied to the trajectories of AVPD and basic personality traits from the Longitudinal Study of Personality Disorders (Lenzenweger, M. F., 2006, The longitudinal study of personality disorders: History, design considerations, and initial findings. Journal of Personality Disorders, 20, 645-670. doi:10.1521/pedi.2006.20.6.645), a naturalistic, prospective, multiwave, longitudinal study of personality disorder, temperament, and normal personality. The focus of these analyses is on the relationship between the rates of change in both AVPD symptoms and basic personality traits. AVPD symptom trajectories demonstrated significant negative relationships with the trajectories of interpersonal dominance and affiliation, and a significant positive relationship to rates of change in neuroticism. These results provide some of the first compelling evidence that trajectories of change in PD symptoms and personality traits are linked. These results have important implications for the ways in which temporal stability is conceptualized in AVPD specifically, and PD in general.

Construct validity of the Schwartz Outcome Scale: validation using a 28-day inpatient chemical rehabilitation patient sample

The Schwartz Outcome Scale-10 (SOS-10) is a 10-item self-report that measures quality of life and psychological well-being. It is easy to administer and score, and past research has revealed its utility, validity, and reliability with different samples (i.e., clinical and nonclinical) and in different clinical settings (i.e., inpatient, outpatient, nonpsychiatry medical settings). The present study looks to investigate the utility of the SOS-10 in measuring psychological well-being and quality of life with the 28-day inpatient chemical dependency sample. In addition, the current study looks to investigate its ability to be used as a treatment outcome measure for chemical-dependent inpatients. The results revealed that the SOS-10 was associated with aspects of interpersonal dependency and alexithymia in predicted ways. The SOS-10 was positively associated to "Healthy Dependence" and negatively related to alexithymia and "Destructive Overdependence" and "Dysfunctional Detachment." The results also showed that the SOS-10 showed healthy change from admission to discharge and that this change was paralleled by healthy change in interpersonal dependency and alexithymia.

Evidence-based pharmacotherapy for personality disorders

Patients with personality disorders are prescribed psychotropic medications with greater frequency than almost any other diagnostic group. Prescribing practices in these populations are often based on anecdotal evidence rather than rigorous data. Although evidence-based psychotherapy remains an integral part of treatment, Axis II psychopathology is increasingly conceptualized according to neurobiological substrates that correspond to specific psychopharmacological strategies. We summarize the best available evidence regarding medication treatment of personality disordered patients and provide optimal strategies for evidence-based practice. Most available evidence is concentrated around borderline and schizotypal personality disorders, with some additional evidence concerning the treatment of avoidant and antisocial personality disorders. Although maladaptive personality symptoms respond to antidepressants, antipsychotics, mood stabilizers, and other medications, evidence-based pharmacotherapy is most useful in treating circumscribed symptom domains and induces only partial improvement. Most available evidence supports use of medication in reducing impulsivity and aggression, characteristic of borderline and antisocial psychopathology. Efforts have also begun to reduce psychotic-like symptoms and improve cognitive deficits characteristic of schizotypy. Indirect evidence is also provided for psychopharmacological reduction of social anxiety central to avoidant personality disorder. Evidence-based practice requires attention to domains of expected clinical improvement associated with a medication, relative to the potential risks. The development of future rational pharmacotherapy will require increased understanding of the neurobiological underpinnings of personality disorders and their component dimensions. Increasing efforts to translate personality theory and social cognitive neuroscience into increasingly specific neurobiological substrates may provide more effective targets for pharmacotherapy.

Social anxiety disorder: questions and answers for the DSM-V

BACKGROUND

This review evaluates the DSM-IV criteria of social anxiety disorder (SAD), with a focus on the generalized specifier and alternative specifiers, the considerable overlap between the DSM-IV diagnostic criteria for SAD and avoidant personality disorder, and developmental issues.

METHOD

A literature review was conducted, using the validators provided by the DSM-V Spectrum Study Group. This review presents a number of options and preliminary recommendations to be considered for DSM-V.

RESULTS/CONCLUSIONS

Little supporting evidence was found for the current specifier, generalized SAD. Rather, the symptoms of individuals with SAD appear to fall along a continuum of severity based on the number of fears. Available evidence suggested the utility of a specifier indicating a "predominantly performance" variety of SAD. A specifier based on "fear of showing anxiety symptoms" (e.g., blushing) was considered. However, a tendency to show anxiety symptoms is a core fear in SAD, similar to acting or appearing in a certain way. More research is needed before considering subtyping SAD based on core fears. SAD was found to be a valid diagnosis in children and adolescents. Selective mutism could be considered in part as a young child's avoidance response to social fears. Pervasive test anxiety may belong not only to SAD, but also to generalized anxiety disorder. The data are equivocal regarding whether to consider avoidant personality disorder simply a severe form of SAD. Secondary data analyses, field trials, and validity tests are needed to investigate the recommendations and options.

Factor structure and diagnostic efficiency of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for avoidant personality disorder in Hispanic men and women with substance use disorders

OBJECTIVE

This study examined the internal consistency, factor structure, and diagnostic efficiency of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), criteria for avoidant personality disorder (AVPD) and the extent to which these metrics may be affected by sex.

METHOD

Subjects were 130 monolingual Hispanic adults (90 men, 40 women) who had been admitted to a specialty clinic that provides psychiatric and substance abuse services to Spanish-speaking patients. All were reliably assessed with the Spanish-Language Version of the Diagnostic Interview for DSM-IV Personality Disorders. The AVPD diagnosis was determined by the best-estimate method. After evaluating internal consistency of the AVPD criterion set, an exploratory factor analysis was performed using principal components extraction. Afterward, diagnostic efficiency indices were calculated for all AVPD criteria. Subsequent analyses examined men and women separately.

RESULTS

For the overall group, internal consistency of AVPD criteria was good. Exploratory factor analysis revealed a 1-factor solution (accounting for 70% of the variance), supporting the unidimensionality of the AVPD criterion set. The best inclusion criterion was "reluctance to take risks," whereas "interpersonally inhibited" was the best exclusion criterion and the best predictor overall. When men and women were examined separately, similar results were obtained for both internal consistency and factor structure, with slight variations noted between sexes in the patterning of diagnostic efficiency indices.

CONCLUSIONS

These psychometric findings, which were similar for men and women, support the construct validity of the DSM-IV criteria for AVPD and may also have implications for the treatment of this particular clinical population.

Avoidant personality disorder and its relationship to social phobia

This review summarizes past and recent findings in the empiric literature and the evolution of the concepts of avoidant personality disorder (APD) and social phobia (SP). APD is an internally consistent dimensional personality pathology that causes dysfunction that appears to be dimensional rather than a sudden jump in impairment after a certain number of criteria have been met. It has state and trait personality components. Evidence indicates that symptoms are at least partially treatable with psychological or pharmacologic interventions. APD and SP have similar symptoms and treatment response and identical genetics. We can conclude from the empiric evidence that no dividing line exists between APD and SP, with APD merely being the more severe form of the disorder. The best conceptualization is that APD is a dimensional personality pathology that in its attenuated form (SP) resembles an anxiety disorder.

The Inventory of Interpersonal Problems (IIP-64) as a Screening Measure for Avoidant Personality Disorder

We investigated the usefulness of the Inventory of Interpersonal Problems (IIP-64) as a screening measure for avoidant personality disorder (AVPD), and for personality disorder (PD) in general. A total of 159 female participants filled out the IIP-64 and then took part in a structured clinical interview for the DSM-IV personality disorders (SCID-II). Interview-based diagnoses of AVPD (N = 21) were predicted with good diagnostic accuracy by a single scale (socially inhibited) of the IIP-64, whereas the presence of any kind of PD (N = 37) was more accurately predicted by the IIP-64 total score. The IIP-64 not only assesses general personality pathology, but may also be used in screening for specific kinds of personality pathology, which have greater clinical relevance.

Generalized social anxiety disorder and avoidant personality disorder: structural analysis and treatment outcome

There has been considerable controversy about whether generalized social phobia (GSP) and avoidant personality disorder (APD) are redundant diagnostic categories. In light of the ongoing controversy, more data are needed to help determine whether GSP and APD are independent constructs. Data were obtained from 335 people seeking treatment for GSP at a two site clinical trial. Indicators of GSP and APD were obtained along with assessments of demographic factors, level of functioning, and indicators of related psychopathology. Confirmatory factor analyses of indicators of GSP and APD suggested a somewhat better fit for a two-factor solution. Comparisons of GSP patients with and without APD suggested that in addition to having more severe social phobia symptoms, patients with APD were more depressed on a self-report measure and had more functional impairment, thereby suggesting potential utility of the diagnostic category of APD. Furthermore, the presence of APD predicted treatment response, in that patients with APD had more change early in treatment than those without APD. APD and GSP remain highly related constructs, and different aspects of these data support and dispute the utility of the diagnosis of APD in GSP. Possible new directions in conceptualizing APD are discussed.

Self-esteem in patients with borderline and avoidant personality disorders

This study compared self-esteem in patients with avoidant personality disorder (APD) and borderline personality disorder (BPD). Patients diagnosed with one or more personality disorders answered the questionnaire Index of Self Esteem as part of a comprehensive evaluation within the setting of a treatment trial. Our hypotheses were that (1) both patients with APD and patients with BPD would report low levels of self-esteem, (2) patients with APD would report lower self-esteem than patients with BPD. We further expected that (3) patients with higher levels of depression would report lower levels of self-esteem, but that (4) both borderline and avoidant personality pathology would contribute to explained variance in self-esteem beyond what would be accounted for by depression. All of our hypotheses were supported. The results from our study showed a significant difference in self-esteem level between the two personality disorders, patients with APD reporting lower self-esteem than patients with BPD. Subjects with both disorders were measured to have self-esteem levels within the range that presumes clinical problems. Self-esteem represents an important quality of subjective experience of the self, and the study of self-esteem in PDs can offer new and important knowledge of PDs as self-pathology.

Generalized social phobia and avoidant personality disorder: meaningful distinction or useless duplication?

Participants with generalized social phobia (GSP) with (n=36) and without (n=19) avoidant personality disorder (AVPD) were compared via contrasts of group means and classification analysis on purported core features of AVPD. GSP-AVPD participants proved to be more severely impaired or distressed on some group contrasts. Cluster analysis identified two groups in the sample, with group membership significantly correlated to AVPD diagnosis. However, almost all significant findings were nullified when severity of social phobia was statistically controlled. Thus, at least where participants with social phobia are concerned, it seems most parsimonious to consider AVPD a severe form of GSP rather than a separate diagnostic category.

World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for biological treatment of personality disorders

These practical guidelines for the biological treatment of personality disorders in primary care settings were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). They embody the results of a systematic review of all available clinical and scientific evidence pertaining to the biological treatment of three specific personality disorders, namely borderline, schizotypal and anxious/avoidant personality disorder in addition to some general recommendations for the whole field. The guidelines cover disease definition, classification, epidemiology, course and current knowledge on biological underpinnings, and provide a detailed overview on the state of the art of clinical management. They deal primarily with biological treatment (including antidepressants, neuroleptics, mood stabilizers and some further pharmacological agents) and discuss the relative significance of medication within the spectrum of treatment strategies that have been tested for patients with personality disorders, up to now. The recommendations should help the clinician to evaluate the efficacy spectrum of psychotropic drugs and therefore to select the drug best suited to the specific psychopathology of an individual patient diagnosed for a personality disorder.

Effectiveness of treatment of childhood memories in cognitive therapy for personality disorders: A controlled study contrasting methods focusing on the present and methods focusing on childhood memories

This study tested the hypothesis that treatment of childhood memories is an effective way to change personality disorder related schemas and psychopathology in cognitive therapy for personality disorders. To test this hypothesis, a crossover design was used to compare the effectiveness of methods focusing on the present and methods focusing on childhood memories. After the exploration period, the therapist focused either first on the present during 24 sessions and than for 24 sessions on childhood memories, or followed the reverse order. Twenty-one patients with one or more Axis II disorders were included. Participants were randomly assigned to order of focus. Results indicate that CT methods focusing on childhood memories produce good outcomes, comparable to those of methods focusing on the present. There was no significant effect of order, but both patients and therapists preferred the past-present order. Total effects of the package were large and were maintained till one-year follow-up (d's 0.97-1.90). Experience of the therapist with CT for personality disorders was related to better outcome (d=0.73).
