The objective of this study is to present the psychoeducational program Egokitzen, a post-divorce intervention for parents and preliminary data on its efficacy, by means of a quasi-experimental design with a wait-list comparison group. This program-Egokitzen-has been recently published following years of development, pilot tests and adaptation, and comprises 11 weekly intervention sessions that focus on three major blocks of content: (a) divorce in itself, (b) interparental conflict; and (c) parenting styles and discipline. Thirty-four parents, with a total number of 51 children-aged 2-23 years-took part in the study. Participants completed measures of interparental conflict, family communication, perception of family relationships, parental symptomatology and children's aggressive and anxiety/depression symptoms before, after the intervention and 6 months on completion of the program. Significant differences were found in terms of the perceived conflict and children's mental health symptoms, especially in the 6-moth follow-up period. More structural variables, such as communication, family satisfaction or parent-child relationships, seem to require more time for noticeable change and stability. We can conclude that, even though the results are exploratory, the Egokitzen program is a very promising initiative for helping prevent and fostering the healthy psychological development of children who are going through the parental divorce process.
