Examination of Clinical and Cognitive Insight in Acute Schizophrenia Patients

Lack of insight or awareness of illness is a hallmark feature of schizophrenic illness and has become an increasingly important area of investigation. Although clinical insight focuses on awareness of illness factors, the concept of cognitive insight focuses on the cognitive processes involved in correcting erroneous judgments and certainty about mistaken judgments. The present study was aimed at further investigating the clinical utility and the statistical coherence of the Beck Cognitive Insight Scale (BCIS) (Beck et al., 2004) in acute schizoaffective and schizophrenia (SZ) patients. The present study examined the internal consistency of the scale, as well as its discriminative and predictive validity relative to a well-established traditional measure of clinical insight in a sample of 50 DSM-IV diagnosed SZ patients, presenting for acute inpatient treatment. The BCIS was found to be an internally consistent and a coherent measure of cognitive insight. The BCIS was unassociated with clinical insight, indicating the 2 constructs share little empirical overlap. Cognitive insight was found to be inversely associated with patients' severity of autistic preoccupation symptoms such that those individuals with more cognitive insight, exhibited fewer autistic/cognitive symptoms. Patients' clinical insight, however, was found to be inversely associated specifically with patients' severity of depression. Additionally, clinical insight was also found to be more impaired in patients residing in nursing home environments relative to their counterparts living in less restrictive settings when outside the hospital. Results are discussed in terms of the relationship between clinical and cognitive insight constructs to SZ symptom domains.
