Although cognitive ability is a known predictor of real-world functioning in schizophrenia, there has been an expanded interest in understanding the mechanisms by which it explains real-world functioning in this population. We examined the extent to which functional capacity (i.e., skills necessary to live independently) mediated the relationship between cognitive ability and both observer and self-reported real-world functioning in 138 outpatients with schizophrenia. Functional capacity significantly mediated the relations between cognitive ability and observer-rated real-world functioning, but not self-reported real-world functioning, with small to medium effect sizes observed for all outcomes. The role of cognitive ability in observer versus self-reported real-world functioning may be explained by different mechanisms.
虽然认知能力是精神分裂症患者在现实生活中表现的已知预测因素，但人们越来越关注理解认知能力在该人群中解释现实生活表现的机制。我们研究了在 138 名精神分裂症门诊患者中，功能能力（即独立生活所需的技能）在多大程度上调节了认知能力与观察者和自我报告的现实生活功能之间的关系。功能能力显著调节了认知能力与观察者评定的现实生活功能之间的关系，但与自我报告的现实生活功能无关，所有结果的效应大小均为小到中等。认知能力在观察者评定的现实生活功能与自我报告的现实生活功能之间的作用可能由不同的机制来解释。
