Preliminay study for the Italian validation of the screen for cognitive impairment in psychiatry (SCIP)

Abstract

Introduction

The screen for cognitive impairment in psychiatry (SCIP) is a brief, accessible scale designed for detecting cognitive deficits in psychiatric disorders.

Objectives

The objective of this study is to test the SCIP's validity as a cognitive test by comparison with standard neuropsychological scale using the Pearson's correlation.

Aims Test the convergent and discriminant validity of the SCIP within the Italian SCIP validation project.

Methods

Patients between 18 and 65 years who are in a stable phase of the disease, diagnosed with schizophrenia, schizoaffective disorder or bipolar I disorder were enrolled in this study, from the community mental health department of Ferrara.

Results

The tests were administered to 110 patients (mean age: 45 ± 11,4) and to 86 controls (mean age: 35 ± 12,6) of both sex. SCIP presents high correlation with the R-BANS total score (P < 0.01) and the subscales (verbal learning test-immediate, working memory, verbal fluency test, verbal learning test-delayed, processing speed test, P < 0.01). There are significant differences (P < 0.01) in all SCIP dimensions between patient and control group (Table 1).

Conclusions

Our analysis confirm the results of the English, French and Spanish version of the SCIP regarding convergent and discriminant validity. The SCIP represents a valid, simple and brief screening tool for the cognitive evaluation of patients with schizophrenia-spectrum disorders.
