Factors intensifying positive symptoms of schizophrenia : A research on strategies to control unwanted intrusive thoughts

探讨精神分裂症患者的思维控制策略与认知功能障碍的关系。一系列研究表明，精神分裂症患者和具有高度分裂型特征的非患者使用更多基于担忧和惩罚的控制策略。这些不适应控制策略与认知功能障碍和外部控制点有关。此外，我们使用面板数据的因果分析来估计思维控制策略和受迫害意念之间的因果关系。结构方程模型的交叉滞后效应模型和同步效应模型的结果表明，基于担心和重评价的策略影响偏执思维的频率和信念，偏执思维的频率影响基于惩罚的策略。

We investigated the relationships with thought control strategies and cognitive dysfunction of schizophrenia. A series of studies showed that schizophrenic patients and non-patients with highly schizotypal traits used more worry- and punishment-based control strategies. These maladaptive control strategies were associated with cognitive dysfunction and an external locus of control. Also, we used causal analyses with panel data to estimate a causal relationship between thought control strategies and persecutory ideation. Results of structural equation modeling using cross-lagged effect models and synchronous effect models suggest that the worry- and reappraisal-based strategies influenced the frequency and conviction of paranoid thoughts, and that the frequency of paranoid thoughts influenced the punishment-based strategies.
