The relationships among cognitive function, social functioning and personality in patients with schizophrenia.

本研究通过相关分析和多元回归分析，探讨了认知功能、社会功能与人格(气质和性格)之间的关系。首先，目前的研究表明，认知功能障碍越严重，社交功能就越差。其次，仅从分层回归分析的结果来看，认知功能与人格(气质和性格)因素的结合对社会功能的预测效果要好于认知功能。然后运用PASS分析方法对认知功能、社会功能和人格之间的关系进行了综合分析。我们发现，自我指导性(SD)越高，总体社会功能越好。我们还发现，高新颖性(NS)会导致更严重的认知功能障碍和更严重的阳性症状。

In the present study, the relationships among cognitive function, social functioning and personality (temperament and character) were examined by correlation and multivariate analyses. First, the present study demonstrated that severer cognitive dysfunction leads to worse social functioning consistently. Second, the present study also showed that the combination of cognitive function and personality (temperament and character) factor predicted social functioning better than cognitive function only from the result of hierarchical regression analysis. Then we comprehensively analyzed the relationships among cognitive function, social functioning and personality using pass analysis. We found that the higher self-directedness(SD), the better general social functioning was. And we also found that the higher novelty-seeking (NS) leads to severer cognitive dysfunction and severer positive symptoms.
