Specific facial emotion recognition deficits across the course of psychosis: A comparison of individuals with low-risk, high-risk, first-episode psychosis and multi-episode schizophrenia-spectrum disorders.

Our study aimed to explore the recognition of specific emotions across the course of psychosis. A visual task representing the six basic emotions was used to assess facial emotion recognition (FER) in 204 healthy controls classified into 152 low-risk (LR) and 52 high-risk for psychosis (HR), following a psychometric risk approach; and 100 patients: 44 with first-episode psychosis (FEP) and 56 with multi-episode schizophrenia-spectrum disorders (MES). First, we performed a MANCOVA to compare the four conditions.

Self-reported cognitive biases in psychosis: Validation of the Davos Assessment of Cognitive Biases Scale (DACOBS) in a Spanish sample of psychotic patients and healthy controls.

Cognitive biases have been demonstrated to be important in developing and maintaining psychosis. However, self-report measures for everyday clinical practice have been developed only recently. We aimed to study one of these instruments for assessing cognitive biases: the Davos Assessment of Cognitive Biases Scale (DACOBS).

Attachment Dimensions predict Social Functioning in persons with Schizophrenia-Spectrum Disorders, regardless of Symptom Severity.

Attachment patterns and early-life adversities are relevant to understand the role of psychosocial factors in the vulnerability and the development of psychosis. The first aim of the study was to test whether a dimensional attachment instrument, the CAMIR (from French; Cartes: Modèles Individuels de Relation), may differentiate attachment styles by comparing a group of psychotic patients with a non-clinical sample. Also, we hypothesised that attachment dimensions would predict Social Functioning (SF) within the clinical group.

The centrality of secure attachment within an interacting network of symptoms, cognition, and attachment dimensions in persons with schizophrenia-spectrum disorders: A preliminary study.

Background: Research in the field of psychosis broadly suggests that symptoms, neurocognitive deficits, social cognition, cognitive biases, and attachment experiences influence each other. However, little is known if any of these constructions play a more central role than others as they interact.

Method: To clarify this issue, we conducted a "network" analysis to explore the interplay among a set of variables related to attachment, cognition domains, and psychotic symptoms in a small sample of outpatients with stabilised schizophrenia-spectrum disorders (n = 25).

Personality disorders in obsessive-compulsive disorder: a comparative study versus other anxiety disorders.

Objective: The purpose of this paper is to provide evidence for the relationship between personality disorders (PDs), obsessive compulsive disorder (OCD), and other anxiety disorders different from OCD (non-OCD) symptomatology.

Method: The sample consisted of a group of 122 individuals divided into three groups (41 OCD; 40 non-OCD, and 41 controls) matched by sex, age, and educational level. All the individuals answered the IPDE questionnaire and were evaluated by means of the SCID-I and SCID-II interviews.

[Involvement of the thalamic-cortical-striatal circuit in patients with obsessive-compulsive disorder during an inhibitory control task with reward and punishment contingencies].

Introduction: Recent neuroimaging studies conducted on obsessive-compulsive disorder (OCD) show alterations in the fronto-thalamic-striatal circuit, which would give rise to an executive dysfunction. This could be the neurocognitive substrate underlying the main symptoms of OCD, i.e.

[The neurobiology of obsessive-compulsive disorder: new findings from functional magnetic resonance imaging (II)].

Introduction: In recent years, neuroscience has shown a growing interest in applying its methods to furthering the knowledge of psychiatric disorders, and one of the fundamental tools used to do so are neuroimaging techniques. Yet, in general, few studies have been conducted in which functional magnetic resonance has been applied in this field and findings are sometimes contradictory.

Aims: In this study we review the specialised bibliography and present a critical discussion on the scientific literature published to date on the application of functional magnetic resonance and diffusion tensor imaging to one of the most widely studied disorders, from a neurobiological point of view, namely, obsessive-compulsive disorder.
