Abstract
The Lausanne Trialogue Play (LTP ) is an instrument that allows the standardized assessment of the family alliance, highlighting the importance of the father in studies of family process and interactions, as also the existence of a triadic family effect since early stages. The present study pretends to contribute to extend the knowledge in family alliances in families with preschool aged children, analyzing it’s relation with the parental mental health variables. 50 parental couples and their children were evaluated at their homes with the following instruments: LTP , BDI-I, PSI-SF and a sociodemographic questionnaire. Results show that most of the families have dysfunctional alliances, without proving a statistically significant relation with the parental studied variables. Nevertheless, families with conflictive alliances tend to show higher levels of depressive symptoms and parental stress, especially in fathers.
