Introduction: Family interventions occupy a leading position for eating disorders (EDs) among psychological treatments. However, the unavailability of family measures specifically validated in such disorders in Spanish population has been documented, to evaluate family dynamics and design appropriate interventions. This study aims to validate the clinical application of the Cuestionario de Evaluación de las Relaciones Familiares Básicas (CERFB; in English, Basic Family Relations Assessment Questionnaire) in EDs.
Method: One hundred and sixty-nine couples (N = 338 participants) with a child with an ED completed the CERFB and other family measures.
Results: The CFA results support the two-factor solution of the original version for general population. Furthermore, measurement invariance across gender results support the configural and metric invariance. Convergent validity is supported by significant correlations between the CERFB and the Dyadic Adjustment Scale and the Parental Bonding Instrument. Reliability is satisfactory for both scales: Marital (α = .90) and Parental (α = .76). Normative data are provided.
Conclusions: The CERFB becomes the only available family measure in EDs for Spanish population offering a broader assessment than existing measures as it comprises both the marital relationship and parenting exercise.
