Adela Pérez, psychiatrist collaborating with the SUCEDE group reviewed the following article: Raballo et al., (2021) The self in the spectrum: a meta-analysis linking basic self-disorders and schizophrenia. Watch it on our YouTube Channel.
Disorders of the ‘Self’ have been extensively studied over the last 20 years, as well as their relationship to schizophrenia and other disorders of its spectrum.
The meta-analysis we review address the existing evidence of the association between the existence of Self disorders and the diagnosis of schizophrenia or other spectrum disorders.
They conducted a literature search of original studies, published in English and carried out with an original sample, in which a measure of Self alterations was performed with any of the tools validated at this time. All studies that included at least two comparison groups were included for meta-analysis.
The results show, in general, a greater association of Self disturbance, with schizophrenia and other diagnoses of the spectrum (first episodes, schizotypy), and also, although with a smaller effect size, in subjects at high risk of psychosis, with respect to individuals with no psychiatric diagnosis or with another diagnosis outside the spectrum.
The authors conclude that there is robust evidence to affirm that there is an association between the existence of alterations of the self and schizophrenia spectrum disorders, thus confirming the interest of studying these alterations both to facilitate the differential diagnosis and to promote the etiopathogenic study of these disorders.
