点模式期望（DPX）任务的创建是为了有效地评估精神分裂症患者的情境处理缺陷。三项研究探讨了与临床应用相关的DPX的特征。为了回答有关该任务的心理测量特性的问题，在2个健康样本中研究了该任务的表现。在大多数情境处理的测量中发现了可接受的信度、内部一致性和重测信度，但在难度控制条件下却没有。这些特征也在建议的简要版本（DPXbrf）中发现，该版本可能更适用于临床目的。在第三项研究中，精神分裂症患者在语境处理中表现出一种特殊的缺陷，与之前的研究结果重复。这些研究的发现表明了在测量上下文处理中使用该任务的一些希望，并确定了该任务需要加强以提高可靠性和可行性的特征。以及单一主体的可解释性。
The dot pattern expectancy (DPX) task was created to efficiently assess context-processing deficits in patients with schizophrenia. Three studies investigated the characteristics of the DPX relevant for clinical applications. To answer questions regarding the psychometric properties of the task, performance on this task was studied in 2 healthy samples. Acceptable reliability and internal consistency and retest reliability were found for most measures of context processing, but not for a difficulty control condition. These characteristics were also found in a suggested brief version (DPXbrf), which may be more practical for clinical purposes. In a 3rd study, schizophrenia patients showed a specific deficit in context processing, replicating previous findings. Findings of these studies indicated some promise for use of this task in measuring context processing and also identified characteristics of this task that need to be strengthened to increase reliability, feasibility. and single-subject interpretability.
