Introduction to the Special Issue: Conceptualization, Assessment, and Treatment of Obsessive-Compulsive Disorder and Co-Occurring Conditions.

Obsessive-compulsive disorder (OCD) has a lifetime prevalence of 1%-2% and typically presents as a chronic condition with significant functional impairment. Comorbidity with OCD is the norm, with 90% of individuals with OCD also meeting diagnostic criteria for a co-occurring condition. Co-occurring conditions can complicate the conceptualization, assessment, and treatment of OCD, such as by intensifying existing symptoms, obscuring differential diagnosis of phenotypically and functionally similar symptoms, and interfering with cognitive behavioral treatment. This two-part special issue reviews extant literature and provides expert advice on conceptualizing, assessing, treating, and researching OCD with co-occurring conditions of depression, posttraumatic stress disorder, eating disorders, schizophrenia, hoarding disorder, panic disorder, obsessive-compulsive personality disorder, and illness anxiety disorder.

The cost and impact of compulsivity: A research perspective.

Compulsivity is the defining feature of various psychiatric disorders including Obsessive Compulsive Related Disorders (OCRDs), and other compulsive, impulsive, and addictive disorders. These disorders are disabling, chronic conditions with an early onset and high rates of comorbidity, misdiagnoses, and delay in treatment onset. Disorders of compulsivity are responsible for considerable socioeconomic burden to society. We review the costs and impacts of compulsivity. In order to facilitate earlier diagnosis and targeted treatments, we examine the overlapping mechanisms that underlie compulsivity. We reconceptualize psychiatric disorders based on core features of compulsivity, highlight challenges in harmonizing research in children and adults, describe newer research methodologies, and point to future directions that can impact the costs and impact of disorders of compulsivity.

[Assessment of personality disorders with the Millon Clinical Multiaxial Inventory (MCMI-II) in a forensic sample]. / Evaluación de trastornos de personalidad mediante el Inventario Clínico Multiaxial (MCMI-II) en una muestra forense.

In this paper, the presence of personality disorders in a forensic sample is analysed using the Millon Clinical Multiaxial Inventory (MCMI-II). The sample was made up of 86 individuals from both civil and criminal settings: plaintiffs in family cases and complainants and defendants in various crimes, especially in partner abuse. The results reveal a great number of records of Compulsive Personality Disorder, reaching 70%, regardless of whether they were from the civil or the criminal setting or whether they were a plaintiff or a defendant. It is concluded that this inventory seems to lack statistical validity for this purpose. Moreover, this test may only describe the typical characteristics of forensic evaluation rather than the personality of the individuals assessed, and it is oversensitive to context; hence, the conclusions derived from the use of the MCMI-II in the forensic field may accept as valid a great deal of distorted or unspecific profiles.

Relationship between clinician assessment and self-assessment of personality disorders using the SWAP-200 and PAI.

The relation between self- and peer-informant reports of personality using psychometric instruments has been the focus of considerable research. The quantified judgments of clinically experienced observers such as treating clinicians have also been studied. The focus of the present article is on the measurement of 3 personality disorders (borderline, antisocial, and obsessive-compulsive) using the Shedler-Westen Assessment Procedure (SWAP-200), an instrument designed to quantify personality ratings made by clinically experienced informants, and the self-report Personality Assessment Inventory (PAI). SWAP-200 personality disorder scales showed small to medium correlations with borderline and antisocial personality disorder scales from the PAI. As predicted, SWAP-200 obsessive-compulsive personality disorder correlated negatively with these scales, suggesting discriminant validity.

Compulsive buying disorder: definition, assessment, epidemiology and clinical management.

Compulsive buying disorder is characterised by excessive or poorly controlled preoccupations, urges or behaviours regarding shopping and spending, which lead to adverse consequences. Compulsive buying disorder has been estimated to affect from 2 to 8% of the general adult population in the US; 80 to 95% of those affected are female. Onset occurs in the late teens or early twenties, and the disorder is generally chronic. Psychiatric comorbidity is frequent, particularly mood, anxiety, substance use, eating and personality disorders. Treatment has not been well delineated, but individual and group psychotherapy, cognitive-behavioural therapy and 12-step programmes may be helpful. Debt consolidation and credit counselling will be appropriate for many individuals who have compulsive buying disorder. Serotonin (5-hydroxytryptamine; 5-HT) re- uptake inhibitors may help some patients regulate their buying impulses. Self-help books are also available.

Peer assessment of personality traits and pathology in female college students.

Assessment procedures for personality disorders (PDs) typically rely on self-reports, even though some people with PDs may be unable to view themselves realistically or are unwilling to report socially undesirable traits. Close associates may provide important information regarding the presence of PD traits. Peer nomination is a reliable and valid assessment procedure that can be adapted to the study of PDs for research purposes. This study focused on characteristic features that define narcissistic, dependent, and obsessive-compulsive PDs using information collected from both self and others in a nonclinical sample of women. It was designed to identify specific areas of agreement and discrepancy between self-report and peer assessment in the measurement of characteristic features of these disorders.

Standardized assessment of personality disorders in obsessive-compulsive disorder.

We assessed 96 patients with obsessive-compulsive disorder for DSM-III personality disorder diagnoses with a standardized interview instrument (Structured Interview for the DSM-III Personality Disorders). Fifty patients (52%) met criteria for at least one personality disorder, with mixed, dependent, and histrionic personality disorders most frequently diagnosed. Compulsive personality disorder was diagnosed in only 6 patients (6%), 5 of whom had had onset of obsessive-compulsive symptoms before the age of 10 years, indicating that DSM-III compulsive personality disorder is not invariably a premorbid condition for the development of obsessive-compulsive disorder. Schizotypal personality disorder, at 5%, was found to be less common than in past samples, reflecting differences in either assessment methods or sampling.
