Interpersonal subtypes within generalized anxiety disorder.
ABSTRACT In this study, we addressed the heterogeneity in interpersonal problems across patients with generalized anxiety disorder (GAD). We assessed interpersonal problems by the Inventory of Interpersonal Problems (IIP-C; Horowitz, Alden, Wiggins, & Pincus, 2000) in a sample of 78 GAD patients. We used IIP-C profiles describing interpersonal characteristics of the total GAD sample as well as clustered GAD interpersonal subtypes. Although the overall sample was located in the friendly submissive quadrant of the circumplex model, this was true only for the Exploitable cluster, which includes more than 50% of the patients. Importantly, clusters of GAD patients with other locations reporting predominantly Cold, Nonassertive, or Intrusive interpersonal problems were also identified. The 4 clusters did not differ in terms of gender, comorbid disorders, or the severity of depression or anxiety. Thus, the assessment of interpersonal problems provides additional diagnostic information covering the heterogeneity of GAD patients. This information could be used for differential indication and individual case formulation in GAD.

ABSTRACT: The context-free diagnoses outlined by the Diagnostic and Statistical Manual of Mental Disorders might not provide enough information to represent the heterogeneity observed in depressed patients. Interpersonal factors have been linked to depression in a mutually influencing pathoplastic relationship where certain problems, like submissiveness, are related to symptom chronicity. This study evaluated interpersonal pathoplasticity in a range of depressive presentations. We examined archival data collected from 407 participants who met criteria for major depressive disorder (MDD), dysthymic disorder (DD), or subthreshold depression (sD). Latent profile analysis (LPA) identified 5 interpersonal subtypes (vindictive, intrusive, socially avoidant, exploitable, and cold). Apart from gender, the subtypes did not differ significantly on demographic characteristics, psychiatric comorbidity, or self-report depression severity. Socially avoidant participants were more likely to meet criteria for a clinical depression diagnosis (MDD or DD), whereas vindictive participants were more likely to have sD. Our results indicate that interpersonal problems could account for heterogeneity observed in depression.Journal of Personality Assessment 03/2015; DOI:10.1080/00223891.2015.1011330 · 2.01 Impact Factor

ABSTRACT: Interpersonal assessment may provide a clinically useful way to identify subtypes of social phobia. In this study, we examined evidence for interpersonal subtypes in a sample of 77 socially phobic outpatients. A cluster analysis based on the dimensions of dominance and love on the Inventory of Interpersonal Problems-Circumplex Scales (Alden, Wiggins, & Pincus, 1990) found 2 interpersonal subtypes of socially phobic patients. These subtypes did not differ on pretreatment global symptom severity as measured by the Brief Symptom Inventory (Derogatis, 1993) or diagnostic comorbidity but did exhibit differential responses to outpatient psychotherapy. Overall, friendly-submissive social phobia patients had significantly lower scores on measures of social anxiety and significantly higher scores on measures of well-being and satisfaction at posttreatment than cold-submissive social phobia patients. We discuss the results in terms of interpersonal theory and the clinical relevance of assessment of interpersonal functioning prior to beginning psychotherapy with socially phobic patients.Journal of Personality Assessment 11/2010; 92(6):514-27.

ABSTRACT: While anxiety has been associated with exaggerated emotional reactivity, depression has been associated with blunted, or context insensitive, emotional responding. Although anxiety and depressive disorders are frequently co-morbid, surprisingly little is known about emotional reactivity when the two disorders co-occur. We utilized the emotion-modulated startle (EMS) paradigm to examine the effects of a concurrent depressive episode on emotional reactivity in young adults with anxiety disorders. Using an archival dataset from a multi-disciplinary project on risk factors in childhood-onset depression, we examined eye-blink startle reactions to late-onset auditory startle probes while participants viewed pictures with affectively pleasant, unpleasant and neutral content. EMS response patterns were analyzed in 33 individuals with a current anxiety (but no depressive) disorder, 24 individuals with a current anxiety disorder and co-morbid depressive episode and 96 healthy controls. Control participants and those with a current anxiety disorder (but no depression) displayed normative linearity in startle responses, including potentiation by unpleasant pictures. By contrast, individuals with concurrent anxiety and depression displayed blunted EMS. An anxiety disorder concurrent with a depressive episode is associated with reactivity that more closely resembles the pattern of emotional responding that is typical of depression (i.e. context insensitive) rather than the pattern that is typical for anxiety (i.e. exaggerated).Psychological Medicine 03/2010; 41(1):129-39.
