Contribution of Analyses on Triadic Relationships to Diagnostics and Treatment Planning in Developmental Psychopathology.

Recent clinical and theoretical research in the field of developmental psychopathology has focused on the importance of interactions in a child's development. The literature has investigated how children's early relationships contribute to the structure and expression of any subsequent psychological problems. The main focus of this pilot study is the application of the Lausanne Trilogue Play paradigm as part of psychodiagnostic assessments to elucidate family functioning in clinical settings. The research aims particularly to observe the characteristics of a family's interactions in the light of their child's psychopathological symptoms, based on a sample of 38 families with school-age children referred to a Neuropsychiatry Unit for Children and Adolescents for emotional or behavioral problems. The children's psychopathological symptoms were assessed by administering the Child Behavior Check List to their parents. Triadic family interactions were observed using the Lausanne Trilogue Play procedure. Statistically significant relationships emerged between the family's interaction patterns and the child's externalizing and internalizing problems, suggesting an interdependence between these relational and individual factors in the development of the young person's psychopathology. The clinical and therapeutic implications of these findings are discussed.
