ABSTRACT

Theory of mind is one of the most intensively studied phenomena in the development of schizophrenic symptoms and impairments in social adjustment. Complex theory of mind processing requires both visual and verbal aspects of the social-perceptual and social-cognitive components of mind reading. Reliable assessment methods are considered essential for the proper conduct of research. The current study aims at investigating the psychometric properties of the Theory of Mind Picture Stories Task (ToM PST). Forty-seven patients with schizophrenia were enrolled in the study from three sites. Data from ToM PST were used for computing the consistency, reliability, and internal and construct validity of the test.

Our preliminary findings showed less appropriate consistency. Therefore, we attempted to carry out structural changes on the task while preserving its scales and subscales, which measure crucial factors of ToM. The newly structured task has four scales. They show proper consistency (Sequencing: Cronbach's α = 0.70, Theory of a Single Person's Mind: α = 0.74, Switching Between Minds: α = 0.70, Comprehension of Misleading Behaviour: α = 0.67, Total: α = 0.80) with appropriate internal and construct validity, a moderate test-retest reliability over a four-month-course, and a proper inter-rater reliability.

重组尺度:精神分裂症样本中心理图片故事任务理论的心理测量特性

摘要

心理理论是精神分裂症症状发展和社会适应障碍中研究最深入的现象之一。心理处理的复杂理论需要心理阅读的社会感知和社会认知成分的视觉和语言方面。可靠的评估方法被认为对于正确进行研究至关重要。当前的研究旨在调查心理图片故事理论任务 (ToM PST) 的心理测量特性。来自三个地点的 47 名精神分裂症患者参加了这项研究。来自 ToM PST 的数据用于计算测试的一致性、可靠性以及内部和结构有效性。

我们的初步调查结果显示不太合适的一致性。因此,我们尝试对任务进行结构更改,同时保留其衡量 ToM 关键因素的尺度和子尺度。新结构的任务有四个尺度。它们表现出适当的一致性(测序:Cronbach's α = 0.70,单人思维理论:α = 0.74,思维转换:α = 0.70,误导行为的理解:α = 0.67,总计:α = 0.80),具有适当的内部和结构效度、四个月课程中的适度重测信度以及适当的评分者间信度。
