Cognitive behavioural therapy (CBT) is effective for at‐risk‐mental state (ARMS) in reducing/delaying transition to psychosis. However, previous systematic reviews pointed out the small number of trials as a limitation and suggested that additional outcomes should be evaluated, not only prevention of first psychosis episode. No study assessed the CBT effects on subclinical psychotic symptoms. The present study investigated the effects of CBT on the transition risk (primary outcome), and on overall remission from ARMS and severity of subclinical symptoms, that is, unusual content of thought, non‐bizarre ideas, perceptual abnormalities, disorganized speech (secondary outcome).

处于危险心理状态的寻求帮助的青少年和年轻人的认知行为疗法：对亚临床阳性症状的影响

认知行为疗法 (CBT) 可有效减少/延迟向精神病的转变，对处于危险中的精神状态 (ARMS) 有效。然而，之前的系统评价指出试验数量少是一个局限性，并建议应评估额外的结果，而不仅仅是预防首次精神病发作。没有研究评估 CBT 对亚临床精神病症状的影响。本研究调查了 CBT 对转变风险（主要结果）、对 ARMS 的总体缓解和亚临床症状严重程度的影响，即不寻常的思想内容、非奇异的想法、知觉异常、言语紊乱（次要结果） ）。
