The English Version of the Schema Inventory for Children: Psychometric Evaluation of a Measure of Early Maladaptive Schemas in a Primary School-Aged Sample.

Early maladaptive schemas (EMSs) are proposed to be maladaptive ways of thinking and feeling that develop from adverse experiences and basic needs not being met in childhood or adolescence. Once developed, EMSs increase vulnerability to psychopathology. Psychometric evaluations of EMS measures in children are scarce. This study aimed to evaluate the psychometric properties of the English version of the Schema Inventory for Children (SIC) in a community sample of youth aged 8 to 13 years. The SIC and measures of positive and negative automatic thoughts, social phobia symptoms, and depressed mood were administered to participants. Although a correlated 11-factor model was expected for the SIC, the optimal factor structure was a correlated six-factor model. EMS subscales corresponding to these six factors had acceptable internal consistency, and they had positive associations with the measures of negative automatic thoughts, social phobia symptoms, and depressive mood, as well as negative associations with the measure of positive automatic thoughts. These results indicate that EMSs in children may not be as differentiated as they are in adults. The results provide evidence for the reliability and validity of the English version of the SIC, justifying its use in contexts requiring the assessment of EMSs in children.
