The current study examined whether changes in core beliefs over time predict positive symptoms, negative symptoms, social functioning, and role functioning within individuals at clinical high risk for psychosis (CHR).
CHR participants (N = 73) completed the Brief Core Schemas Scale (BCSS) at baseline, with a subset of participants (n = 54) completing study procedures at a 12-month follow-up. Attenuated psychotic symptoms, social, and role functioning were assessed at both timepoints.
Hierarchical regression analyses showed that changes in self-beliefs between baseline and follow-up predicted worsening social and role functioning at 12-month follow-up, with trends suggesting they also predicted negative and positive symptoms at 12-month follow-up. The independent effect of an increase in negative self-beliefs marginally or significantly predicted all outcomes of interest.
The current study shows incremental validity of self-beliefs from a novel perspective. It suggests that worsening self-beliefs have a clinically meaningful impact within CHR populations.
本研究旨在探讨核心信念随时间的变化是否能预测处于精神病高危状态（CHR）个体的阳性症状、阴性症状、社会功能和角色功能的变化。
CHR 参与者（N=73）在基线时完成了简明核心图式量表（BCSS），其中一部分参与者（n=54）在 12 个月的随访时完成了研究程序。在两个时间点都评估了减轻的精神病症状、社会和角色功能。
层次回归分析表明，基线和随访之间自我信念的变化预测了 12 个月随访时社会和角色功能的恶化，趋势表明它们也预测了 12 个月随访时的阴性和阳性症状。消极自我信念的增加具有边际或显著的独立预测作用，预测了所有感兴趣的结果。
本研究从一个新的角度展示了自我信念的增量有效性。它表明，自我信念的恶化在 CHR 人群中具有临床意义。
