[en] Acording to Emotional Security Theory (EST), interparental conflict, especially destructive conflict characterized by intense, frequent and unsolved conflicts, decreases children´s and adolescents´ security in their family system. The aim of this study was to analyze the impact that interparental conflict has on two subsamples of Spanish adolescents´emotional security. Participants were 907 adolescents divided into two subsamples: one sample of 169 adolescents living in residential care under the child protection services and another community sample of 738 adolescents. The Children´s Perception of Interparental Conflict Scale (CPIC) was used to explore interparental conflict dimensions. To analyse adolescents´ emotional security, the Security in the Family System Scale (SIFS) was applied. Results indicated that destructive interparental conflict was significantly higher in the families of adolescents in residential care, and so, their emotional security was significantly lower. But, regardless these differences, there seems to be similar variables that affect adolescents´ security in their family system in both subsamples: the parents´ resolution of their arguments and the frequency of their fights. Analyses also indicate that interparental conflict was a perceived differently and differently affected boys´ and girls´ emotional security. Thus, girls in both samples significantly disengaged more than boys when facing interparental conflict. Emotional security is an appropriate framework to study the impact that interparental conflict has on Spanish adolescents, even when children are not currently living with their parents.

[gl] De acordo coa Teoría da Seguridade Emocional (EST) o conflito interparental, especialmente o destrutivo caracterizado por alta intensidade, frecuencia e non resolto, fai que decreza a seguridade no sistema familiar dos pequenos e dos adolescentes. O principal obxectivo deste estudo é analizar o impacto do conflito interparental en dúas submostras de adolescentes españois. Os participantes foron 907 adolescentes divididos en duas submostras: unha de 169 adolescentes que viven en centros residenciais baixo os servizos de protección de menores e outra composta por 738 adolescentes. A "Escala de Conflicto Interparental desde la perspectiva de los hijos; CPIC" foi empregado para explorar as dimensións do conflito interparental. Para analizar a seguridade emocional aplicouse "Security In the Family System; SIFS". Os resultados indican que o conflito interparental destrutivo foi significativamente máis alto en familias de adolescentes de centros de menores e, ademais, a súa seguridade emocional era significativamente máis baixa. En canto ás diferenzas hai variables similares que afectan á seguridade dos adolescentes na súas familias nas dúas submostras: a resolución dos pais ás súas disputas e a frecuencia das discusións. As análises indican que o conflito interparental foi percibido de xeito diferente e diferentemente afecta á seguridade emocional dos rapaces e das rapazas. De feito, en ambas mostras as rapazas desvinculábanse máis que os rapaces cando se enfrentaban ó conflicto interparental. A seguridade emocional é un modelo teórico axeitado para o estudo do impacto que o conflito interparental ten nos adolescentes españois, aínda cando os rapaces/as non viven cos seus pais.
