Dimensionality analysis of the German version of the Screen for Cognitive Impairment in Psychiatry (SCIP-G).

Background: Psychiatric disorders, especially schizophrenia, are characterised by cognitive impairment. The rapid detection of cognitive dysfunction - also in the course of the disease - is of great importance. The Screen for Cognitive Impairment in Psychiatry (SCIP) was developed to provide screening of psychiatric patients in clinical practice and is available in several languages.

Screening for cognitive impairment in schizophrenia: Psychometric properties of the German version of the Screen for Cognitive Impairment in Psychiatry (SCIP-G).

Background: The Screen for Cognitive Impairment in Psychiatry (SCIP) is a brief scale designed for detecting cognitive deficits in patients with psychiatric disorders including schizophrenia. In this preliminary study the psychometric properties of the German version of the SCIP are examined in a sample of patients with schizophrenia and schizoaffective psychosis (DSM-IV) as well as in healthy controls.

Methods: Thirty patients and thirty matched controls were asked to complete two versions of the SCIP separated by two-week intervals in addition to psychiatric and neurocognitive instruments including assessments to measure psychosocial functioning.

Screening for cognitive dysfunction in unipolar depression: Validation and evaluation of objective and subjective tools.

Background: Persistent cognitive dysfunction in unipolar depression (UD) contributes to socio-occupational impairment, but there are no feasible methods to screen for and monitor cognitive dysfunction in this patient group. The present study investigated the validity of two new instruments to screen for cognitive dysfunction in UD, and their associations with socio-occupational capacity.

Method: Participants (n=53) with UD in partial or full remission and healthy control persons (n=103) were assessed with two new screening instruments, the Danish translations of the Screen for Cognitive Impairment in Psychiatry (SCIP-D) and Cognitive Complaints in Bipolar Disorder Rating Assessment (COBRA) and with established neuropsychological and self-assessment measures.

Optimising screening for cognitive dysfunction in bipolar disorder: Validation and evaluation of objective and subjective tools.

Introduction: Cognitive impairment is common in bipolar disorder and contributes to socio-occupational difficulties. The objective was to validate and evaluate instruments to screen for and monitor cognitive impairments, and improve the understanding of the association between cognitive measures and socio-occupational capacity.

Methods: Patients with bipolar disorder in partial or full remission (n=84) and healthy controls (n=68) were assessed with the Screen for Cognitive Impairment in Psychiatry (SCIP), Cognitive Complaints in Bipolar Disorder Rating Scale (COBRA), and established neuropsychological tests and subjective rating scales.

MMPI-2 restructured form over-reporting scales in first-episode psychosis.

MMPI-2-RF over-reporting scales for physical, cognitive, or psychological symptoms were examined in 130 consecutive referrals to a first-episode psychosis (FEP) clinic. Although acutely ill upon presentation, consistent and responsive profiles were obtained in 79% of the sample. There was no indication of under-reporting on defensive scales, and anticipated elevations were observed on clinical scales sensitive to thought disorder, ideas of persecution, and aberrant experiences.
