Longitudinal course of core cognitive domains in first-episode acute and transient psychotic disorders compared with schizophrenia.

Acute and transient psychotic disorder (ATPD) is characterized by acute onset of psychotic symptoms and early recovery. Contrastingly, schizophrenia (SZ) is a chronic mental disorder characterized by impaired functioning including a deficit in cognition. In SZ, the cognitive deficit is among the core symptoms, but in ATPDs, the existing evidence brings mixed results.

Cognitive flexibility in schizophrenia: A confirmatory factor analysis of neuropsychological measures.

Cognitive flexibility (CF) is the ability to adapt cognitive strategies according to the changing environment. The deficit in CF has often been linked to various neurological and psychiatric disorders including schizophrenia. However, the operationalization and assessment of CF have not been unified and the current research suggests that the available instruments measure different aspects of CF.

Smoking and attention in schizophrenia spectrum disorders: What are we neglecting?

Introduction: Individuals with schizophrenia spectrum disorders (SSDs) record elevated rates of smoking, which is often attributed to their effort to self-medicate cognitive and attentional symptoms of their illness. Empirical evidence for this hypothesis is conflicting, however. In this study, we aimed to test predictions derived from the cognitive self-medication hypothesis.

The relationships between cognitive reserve, cognitive functioning and quality of life in first-episode schizophrenia spectrum disorders.

Cognitive reserve (CR) has been conceptualized as an individual's ability to optimize or maximize performance through differential recruitment of brain networks. As such, CR may contribute to the heterogeneity of cognitive deficits observed in schizophrenia. This study aimed to assess the relationships between CR, cognition and quality of life in first-episode (FES) patients.

Are one's attachment avoidance toward a particular person and his/her placement of this particular person in the attachment hierarchy inversely overlapping? Four bifactor-analysis studies.

Do one's hierarchical preference for attachment support from a particular person over other people (attachment hierarchy) and his/her discomfort with closeness and uneasiness about being dependent on that particular person (attachment avoidance) inversely overlap? These two constructs have been distinctly conceptualized. Attachment hierarchy has been regarded as a normative characteristic of attachment relationships, while attachment avoidance has been considered to reflect an individual difference of relationship quality. Employing bifactor analyses, we demonstrated a unidimensional general factor of these two concepts in four studies exploring Czech young adults' relationships with mother, father, friends, and romantic partner (Study 1); U.
