Dimensionality and Measurement Invariance of a Brief Form of the Young Schema Questionnaire for Adolescents

The current work aims to develop and examine the psychometric properties of the Brief form of the Young Schema Questionnaire for Adolescents (B-YSQ-A), so that Early Maladaptive Schemas can be accurately measured in younger populations. Early Maladaptive Schemas are self-defeating core themes underlying maladaptive cognition, affect, and behavior. A community sample of 877 adolescents, aged 12–18 years old, filled out self-report instruments on maladaptive schemas, anger management, and internalizing and externalizing symptoms. The items composing the B-YSQ-A were selected based on statistical and content analyses criteria. Its internal structure, reliability, age- and gender-based invariance, and between-gender mean differences were examined, as well as its relationship with external variables. Results indicated a satisfying fit for the 18 original schema factors through confirmatory factor analysis. These schemas also showed adequate internal consistency and test-retest reliability, with the exception of the entitlement/grandiosity and self-sacrifice schemas. The B-YSQ-A was found to be age and gender invariant. Concerning gender differences, boys scored higher on the entitlement/grandiosity, insufficient self-control/discipline, approval/recognition seeking, unrelenting standards/hyper-criticalness and punitiveness schemas, whereas girls scored higher on the abandonment/instability, mistrust/abuse, and self-sacrifice schemas. Furthermore, evidence was found for construct validity in relation to measures of internalizing and externalizing symptomatology and of anger expression. Findings offer support for the use of the B-YSQ-A with adolescents, both for research and intervention purposes.
