Bipolar II disorders in six first-degree relatives
1993
As proposed by Dunner et al (1976), the distinction of bipolar !! disorder from other effective disorders has been included in Research Diagnostic Criteria (RDC) (Spitzer et al 1978) but not in DSM-IiI-R or ICD 10 (APA 1987, WHO 1991). Family studies indicate that bipolar 1I disorder might represent a distinct diagnostic entity with a common genetic background (Gershon et al 1982; Dunner 1983; Endicott et al 1985; Andreasen et al 1987). Familial aggregation, diagnostic stability, and course of illness represent external validators for nosologic classifications (Kendler 1990). Therefore, pedigrees with multiple cases of diagnostically stable bipolar Ii disorder without cases of bipolar 1 dis…
Searching for a Gastrointestinal Subgroup Within the Somatoform Disorders
2001
The authors examined whether patients suffering from functional gastrointestinal symptoms constitute a separate group within the broader concept of the somatoform disorders. The authors compared 103 patients with a severe gastrointestinal syndrome, 220 patients with a somatization syndrome according to DSM-IV, and 250 clinical control subjects with nonsomatoform mental disorders. The gastrointestinal group showed more catastrophizing thinking, complained more about autonomic sensations, felt bodily weaker, was less tolerant towards bodily discomfort, had developed more hypochondriacal fears and behaviors, was more depressed, and was more severely disabled in different areas of psychosocial …
The Factorial Structure of the Outcome Questionnaire-45: A Study with an Italian Sample.
2008
In this article, the authors study the factorial structure of the Italian translation of the Outcome Questionnaire 45 (OQ-45) in a sample of college students (n = 522) and psychiatric outpatients (n = 301). The relative goodness of fit of six competing models of the OQ-45 was examined using confirmatory factor analysis (CFA). Specifically, the study examined the relative fit of the most frequently presented models in the literature and three alternative models. Results of the CFA provided support for the four factor bi-level solution, suggesting that the OQ-45 is a multidimensional instrument that contains one general factor and multiple unique subscale factors.
The Calgary Depression Rating Scale for Schizophrenia: development and interrater reliability of a German version (CDSS-G)
1999
A German version of the Calgary Depression Rating Scale for Schizophrenia (CDSS-G) approved by the author of the original scale is presented comprising a semi-structured interview for 9 items to sensitively and specifically assess depression in schizophrenia and related disorders. The process of translation is outlined and the finally derived CDSS-G was investigated with respect to interrater reliability in three studies. To keep comparability with the CDSS source version a standard procedure was used. Two trained raters jointly assessed ten schizophrenic patients (study I). In a second study, videotapes with the CDSS-G were presented to clinically inexperienced raters (study II, N = 14/15)…
Escalation from normal appearance related intrusive cognitions to clinical preoccupations in Body Dysmorphic Disorder: A cross-sectional study
2018
Abstract Current cognitive approaches to Body Dysmorphic Disorder (BDD) assume that appearance-related intrusive cognitions and their functional consequences characterize the disorder, in a similar way that obsessive intrusive thoughts characterize the Obsessive-Compulsive Disorder (OCD). This study explores whether normal but unwanted appearance-related intrusive thoughts (AITs), escalate to clinical AITs when they are dysfunctionally appraised and instigate counterproductive neutralizing strategies. From a sample of 344 non-clinical individuals who reported a highly upsetting AIT during the past three months two subgroups were extracted according to their high (n = 68) and low (n = 276) v…
A novel approach to challenging OCD related beliefs using a mobile-app: An exploratory study
2017
Abstract Background and objectives According to cognitive models, obsessive compulsive symptoms result from catastrophic misinterpretations of commonly occurring intrusive experiences and the use of counterproductive strategies to manage them. Obsessive Compulsive Disorder (OCD) related beliefs such as inflated responsibility, importance of thoughts and perfectionism increases the likelihood of such misinterpretations. Consistent with a growing body of literature supporting the usefulness of mobile delivered technologies in fostering cognitive behavior change, the present study assessed the effectiveness of a novel cognitive training exercise designed to challenge OCD-related beliefs. This …
Effects of suppressing neutral and obsession-like thoughts in normal subjects: beyond frequency
2004
Abstract Recent cognitive-behavioral theories on obsessive–compulsive disorder (OCD) show that deliberate attempts to suppress intrusive and undesirable thoughts lie at the genesis of clinical obsessions. In this paper the results of an experimental study on the suppression of neutral and obsession-like thoughts in normal subjects are presented. Eighty-seven university students performed in three experimental periods: (1) base-line monitoring, (2) experimental instruction, and (3) monitoring. For each of these periods, the frequency of the occurrence of a “white bear” thought or a personally relevant intrusive thought was registered. Half of the subjects received instructions to suppress th…
Dysmorphic and illness anxiety‐related unwanted intrusive thoughts in individuals with obsessive–compulsive disorder
2021
Background/objective Unwanted intrusive thoughts (UITs) are considered normal variants of the obsessions found in obsessive-compulsive disorder (OCD). Similarly, intrusive and persistent preoccupations about appearance defects in body dysmorphic disorder (BDD) and images and thoughts about illness in illness anxiety disorder (IAD) are abnormal variants of the thoughts and concerns about appearance and health found in non-clinical individuals. This study examines whether patients with OCD have frequent and distressing UITs with contents related to BDD and IAD, in addition to OCD-related UITs. Method Thirty-nine participants with OCD (Mage = 32.45, standard deviation [SD] = 11.57; 63% men) co…
Dysfunctional belief domains related to obsessive-compulsive disorder: a further examination of their dimensionality and specificity
2010
International consensus has been achieved on the existence of several dysfunctional beliefs underlying the development and/or maintenance of the Obsessive-Compulsive Disorder (OCD). Nevertheless, questions such as the dimensionality of the belief domains and the existence of OCD-specific dysfunctional beliefs still remain inconclusive. The present paper addresses these topics through two different studies. Study 1: A series of confirmatory factor analyses (N= 573 non-clinical subjects) were carried out on the Obsessive Beliefs Spanish Inventory-Revised (OBSI-R), designed to assess dysfunctional beliefs hypothetically related to OCD. An eight-factor model emerged as the best factorial soluti…
Cognitive therapy for autogenous and reactive obsessions: Clinical and cognitive outcomes at post-treatment and 1-year follow-up
2009
This study provides data about the differential effectiveness of cognitive therapy (CT) for obsessive-compulsive disorder (OCD) symptom presentation. Two OCD manifestations, autogenous and reactive, are considered. Seventy OCD patients started CT; 81.40% completed it and 72.85% were available 1 year later. Fifteen of the 57 treatment completers had autogenous obsessions, whereas 33 had reactive obsessions. Nine patients had both obsession modalities. Reactive patients were more severe, as they scored higher on thought suppression and on the dysfunctional beliefs of intolerance to uncertainty and perfectionism. Autogenous patients scored higher on the over-importance of thoughts beliefs. Alt…
