Aim of the study: The Childhood Experience of Care and Abuse Questionnaire (CECA.Q) is a semi-structured self-report that has been developed to record a history of adverse childhood experiences (ACEs). Moreover, the CECA.Q has been widely used in subjects with psychotic disorders. In this study, we aimed to investigate psychometric properties of the Polish version of the CECA.Q in individuals with schizophrenia spectrum disorders. Material and methods: The CECA.Q was administered to 127 individuals with schizophrenia spectrum disorders (aged 39.1 ± 13.8 years, 48.0% males). Internal consistency was assessed using the Cronbach’s  and polychoric correlations. Confirmatory factor analysis (CFA) was performed using the unweighted least squares estimation method. Results: The Cronbach’s  was as follows: 0.835 for mother antipathy, 0.780 for mother neglect, 0.845 for father antipathy, 0.849 for father neglect, 0.787 for mother physical abuse, 0.831 for father physical abuse and 0.870 for sexual abuse, indicating acceptable-to-good internal consistency. Correlations of single item scores with the total scores of specific categories of ACEs were significant. The CFA confirmed factorial structure of the CECA.Q with acceptable goodness-of-fit indices. Conclusions: The present study indicates good psychometric properties of the CECA.Q in subjects with schizophrenia spectrum disorders. This self-report can be implemented by studies investigating ACEs in this clinical population in Poland.
