The Inventory of Psychotic-Like Anomalous Self-Experiences (IPASE) is a self-report measure of minimal self-disturbance. The aim of the current report was to assess the construct validity of the scale by examining its convergent validity with the gold-standard measure of minimal self-disturbance, the Examination of Anomalous Self-Experience (EASE), and its discriminant validity.
The sample consisted of 46 participants (21 ultra-high risk for psychosis patients, 14 first episode psychosis patients, 11 healthy controls). Correlations between the clinical instruments were examined.
The IPASE correlated strongly with general psychopathology and positive psychotic symptoms, moderately with negative symptoms, and weakly with manic symptoms. The strongest correlation (r = 0.92) was apparent between IPASE and EASE total scores.
These preliminary data indicate construct validity of the IPASE, demonstrating both convergent and discriminant validity. The IPASE may be suitable as a screener measure for minimal self-disturbance, but should not be used as a replacement to measure the construct of minimal self-disturbance, which requires considerable psychopathological sophistication.
类似精神病的异常自我体验清单(IPASE)是一种自我报告的轻度自我障碍测量工具。本报告的目的是通过检查其与轻度自我障碍的金标准测量工具——异常自我体验检查(EASE)的趋同效度及其判别效度,来评估该量表的结构效度。
该样本由 46 名参与者(21 名精神病超高风险患者、14 名首发精神病患者、11 名健康对照者)组成。检查了临床工具之间的相关性。
IPASE 与一般精神病理学和阳性精神病症状高度相关,与阴性症状中度相关,与躁狂症状弱相关。与 EASE 总分的相关性最强(r=0.92)。
这些初步数据表明 IPASE 具有结构效度,表现出趋同和判别效度。IPASE 可能适合作为轻度自我障碍的筛查测量工具,但不应作为测量轻度自我障碍结构的替代方法,因为这需要相当程度的精神病理学复杂性。
