Abstract

Background and objectives

Anomalous self-experience, or the experience of the self, are frequently present but underexplored in patients with schizophrenia. Unfortunately, to date, there are no available inventories in Spanish to assess these self-experiences. The present study aims to adapt and validate the Inventory of Psychotic-Like Anomalous Self-Experiences (IPASE) in the Spanish population.

Methods

A total of 171 participants were included: 112 cases (patients) and 59 healthy controls. Among them, 87 patients were diagnosed with schizophrenia (70 chronic and 17 first-episode patients) and 25 patients with bipolar disorder. The participants were evaluated using the structured clinical interview DSM-IV and were tasked with completing the Spanish version of the IPASE. The properties of the scale were analysed in terms of internal consistency, stability, and correlation between scores on the subscales with sociodemographic and clinical variables.

Results

The IPASE showed good reliability (Cronbach's alpha coefficient of 0.847) and intraclass correlation,with a value of 0.837 for the patient group and 0.812 for the control group. The variables of age and sex did not significantly correlate with the total IPASE score. Compared to healthy controls, cases obtained significantly higher overall scores on the IPASE and its five subscales; total scores on the IPASE (Cases: (20.96 ± 42.5)vs. control:(80.56 ± 20.6), p < 0.001).

Conclusions

The Spanish version of the IPASE scale shows good psychometric properties in terms of reliability and validity for its application in assessing alterations in subjective self-experiences in patients with schizophrenia. This demonstrates the value of the IPASE as a tool in both clinical practice and research.

精神病样异常自我体验量表（IPASE）在西班牙语中的改编与验证以评估异常自我体验

背景与目的异常的自我体验或自我体验在精神分裂症患者中经常出现，但尚未得到充分的研究。不幸的是，到目前为止，还没有可用的西班牙语清单来评估这些自我体验。本研究的目的是适应和验证的清单精神病样异常自我经验（IPASE）在西班牙人口。方法共171例受试者：112例（患者）和59例健康对照。其中87例患者被诊断为精神分裂症（70例慢性，17例首发），25例患者被诊断为双相情感障碍。参与者使用结构化临床访谈DSM-IV进行评估，并完成西班牙语版IPASE。量表的性质根据内部一致性、稳定性以及各子量表得分与社会人口学和临床变量之间的相关性进行了分析。结果IPASE具有良好的信度（Cronbach’s alpha系数为0.847）和类内相关性，其中患者组为0.837，对照组为0.812。年龄和性别变量与IPASE总分无显著相关。与健康对照相比，病例在IPASE及其五个分量表上获得了显著更高的总分；IPASE总分(病例：（20.96±42.5）vs。对照组：（80.56±20.6），p <；0.001)。结论西班牙语版IPASE量表在评估精神分裂症患者主观自我体验改变方面具有良好的信度和效度。这证明了IPASE作为临床实践和研究工具的价值。

期刊介绍： The European journal of psychiatry is a quarterly publication founded in 1986 and directed by Professor Seva until his death in 2004. It was originally intended to report “the scientific activity of European psychiatrists” and “to bring about a greater degree of communication” among them. However, “since scientific knowledge has no geographical or cultural boundaries, is open to contributions from all over the world”. These principles are maintained in the new stage of the journal, now expanded with the help of an American editor.
