Is there really a dissociation between consciousness of cognitive deficits and insight into the symptoms of the disease in schizophrenia?

摘要

In a recent study published in Schizophrenia Research, Lecardeur et al. (2009) explored the relationships between cognitive complaints assessed by the Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS, Stip et al., 2003) and one of the multiple cognitive components of the Positive and Negative Syndrome Scale (PANSS) described in the literature (Lindenmayer et al., 1994). A strong relationship between the PANSS cognitive component following Lindenmayer et al.'s (1994) five-factors model and SSTICS total score was shown in their sample (n=71, r=0.338; p=0.004). In addition, no correlation between the G12 insight item of the PANSS and cognitive complaints was found, leading authors to propose that consciousness of cognitive deficits may be independent of insight into the symptoms of the disease. In the present study, Lecardeur et al. (2009) suggested that patients with schizophrenia might be conscious of their cognitive deficits in spite of a lack of insight concerning their psychotic symptoms.
