La percepción de la funcionalidad familiar. Confirmación de su estructura bifactorial (The perception of the family functionality. Confirmation of its bifactorial structure)

Valid, reliable and easy-to-use instruments are required for the assessment of family functionality. The present study confirms the two-factor structure of a 23-item family Functionality Scale, providing indices of reliability and external validity in a sample of 185 families with teenage children. Parent discrepancy is analyzed, and the statistical descriptors of this variable are presented in the two dimensions that constitute the scale: Facilitator and Disturber. The instrument is useful for assessing functionality and for calculating parental discrepancy in the perception of family life, which is also an indicator of functionality.
