Evolution of Family Alliance in Families With a Designated Adolescent Patient (12-18 Years) During a Family Therapy Process

The proposed study focuses on the relational characteristics of the family and their evolution in the course of family therapy, through the evolution of the family alliance (degree of coordination achieved by its members to perform a task) and co-parenting (support that the mother and father give each other in their roles as parents), assuming that the family therapy allows the improvement of these two aspects. The family alliance is evaluated via a standardized observation situation (Lausanne Family Play LFP adapted from the Lausanne Trilogy Play LTP) whose sessions are filmed. The alliance assessment is carried out by the coding and scales of the FASS (Family Alliance Assessment Scales,) tool during viewing.
