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.

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.
