Spanish adaptation of the Beck Cognitive Insight Scale (BCIS) for schizophrenia.

INTRODUCTION

The Beck Cognitive Insight Scale has been designed to evaluate the cognitive insight capacity, that is to say, the practice of self-reflectiveness as a meta-cognitive mechanism for examining and analysing the disorder's symptoms, it also permits a continuous re-evaluation of inadequate interpretations.

METHODOLOGY

The aim of this study is to examine the psychometric properties, the dimensional structure and the internal validity of the Spanish version of Beck's Cognitive Scale of Insight (BCIS). In this paper we also analyse its relation with the Positive and Negative Symptoms Scale (PANSS). The Cognitive Insight Scale was translated and adapted to Spanish with 129 in- and out-schizophrenic patients.

RESULTS

Principal component analysis showed a two-factor structure that was similar to the original one, recognizable as self-reflectiveness (R) and self-certainty (C) with similar reliability as the American version. Self-reflectiveness and the R-C index correlated with loss of insight of the PANSS scale. In general, BCIS showed significant associations with the PANSS subscales. Out patients scored self-reflectiveness and R-C index signicantly higher than in-patients and lower in self-certainty.

CONCLUSION

Psychometric properties obtained with the adapted Spanish version of BCIS guarantee the adequate evaluation of cognitive insight.
