Description

Antecedentes: El Inventario de Apego a Padres e Iguales (IPPA) es un instrumento reconocido internacionalmente para evaluar el apego de adolescentes hacia padres e iguales. El objetivo de este estudio ha sido examinar las propiedades psicométricas del IPPA en una muestra de adolescentes españoles con problemas de conducta. Método: La muestra estaba compuesta por 294 adolescentes españoles (53% chicas) con problemas de conducta. Se administraron las versiones de IPPA madre, IPPA padre e IPPA iguales, junto con otras medidas relacionadas. Resultados: Se ha confirmado la escala de 25 ítems, distribuida en tres factores, para la versión IPPA madre e IPPA padre, pero no para la versión de iguales. El IPPA ha mostrado valores adecuados de fiabilidad que oscilaban entre .79 y .86. La validez se demostró mediante las correlaciones significativas con las variables inteligencia emocional, conducta antisocial y agresividad. Conclusiones: La versión de tres factores del IPPA es una escala útil, fiable y válida para evaluar el vínculo de adolescentes que muestran conductas problemáticas con sus padres.

Abstract

Background: The Inventory of Parental-Peer Attachment (IPPA) is an internationally recognized measure to assess the attachment of adolescents to their parents and peers. The objective of this study was to examine the psychometric properties of the IPPA in a sample of Spanish adolescents with behavioural problems. Method: The sample was composed of 294 Spanish adolescents (53% girls) with behavioural problems. The IPPA mother, father, and peer versions, along with other related measures, were administered. Results: The 25-item scale, distributed into three factors, was confirmed for both the mother and father versions but not for the peer version. The IPPA showed adequate values of reliability ranging from .79 to .86. Validity was demonstrated through correlations with emotional intelligence, antisocial behaviour, and aggressiveness. Conclusion: The three-factor version of the IPPA is a useful, reliable, and valid scale to assess the attachment of adolescents with problematic behaviours and their parents.
