This pioneering study aims to associate the quality of the therapeutic alliance between therapist and parents with the quality of the therapeutic relationship between the child and the therapist. The goal is to understand how these two variables are connected. The sample was composed of 21 dyads father/mother-child. They assessed individually the therapeutic relationship established with the therapist. The assessed dimensions were the quality of relationship, objectives and tasks of the therapeutic process. Results not found an association between the overall therapeutic relationships of parents and children with therapist. However, some secondary correlations were found. Guidelines and recommendations for future replication of this study are discussed.
