Research has demonstrated that functional outcome in psychosis is predicted by factors such as neurocognition, functional capacity, symptoms and, more recently, metacognition. Metacognitive ability has been demonstrated to mediate between neurocognition and functional outcome in First Episode Psychosis (FEP). Whether metacognition also predicts longer-term recovery in first episode psychosis is unknown. This study assessed whether neurocognition, functional capacity and metacognitive ability in FEP predicted functional outcome three years later. Eighty individuals with First Episode Psychosis were re-contacted after an average 3 years (range: 26-45 month follow-up) from baseline. Twenty-six participants (33%) completed completed measures of neurocognition, metacognition, functional capacity, functional outcome (hours spent in structured activity per week) and psychopathology at baseline and at follow-up. Individual regression analyses demonstrated neurocognition, functional capacity, and metacognitive ability at baseline significantly predicted functional outcome at three years. However, when baseline functional outcome was controlled, only metacognitive ability was a significant predictor of change in functional outcome from baseline to follow-up, < 0.001. This model explained 72% (adjusted = 0.69) of the variance in functional outcome at follow-up. Negative symptoms did not change the model. This study demonstrated that better metacognitive ability significantly predicted improvement in functioning in FEP across a 3-year period. This highlights the potential value of clinical interventions that focus on improving metacognitive ability at first point of illness to maximize recovery.
研究表明,精神病的功能结局可由神经认知、功能能力、症状以及最近的元认知等因素预测。元认知能力已被证明在首发精神病(FEP)的神经认知和功能结局之间起中介作用。元认知是否也能预测首发精神病的长期康复尚不清楚。本研究评估了首发精神病患者的神经认知、功能能力和元认知能力是否能预测三年后的功能结局。80名首发精神病患者在距基线平均3年(随访范围:26 - 45个月)后再次接受评估。26名参与者(33%)在基线和随访时完成了神经认知、元认知、功能能力、功能结局(每周花在结构化活动上的小时数)和精神病理学的测量。个体回归分析表明,基线时的神经认知、功能能力和元认知能力显著预测了三年后的功能结局。然而,当控制基线功能结局时,只有元认知能力是从基线到随访功能结局变化的显著预测因素,<0.001。该模型解释了随访时功能结局方差的72%(调整后=0.69)。阴性症状并未改变该模型。本研究表明,更好的元认知能力显著预测了首发精神病患者在3年期间功能的改善。这突出了在疾病初期专注于提高元认知能力以最大化康复的临床干预的潜在价值。
