According to the results of previous research, Filial Therapy studies have led to an improvement in parents' awareness of their children's needs, their emphatic behaviors, therapeutic reactions towards their children, projective statements, acceptance of children's emotions and behaviors, problem solving skills, and relationship in the dimensions of loyalty, sincerity and communication. Practical studies conducted by using different variables and in different cultures revealed the effectiveness of Filial Therapy. This study aims to examine the effects of a Mother Training Program Based on Filial Therapy on the interaction between mothers and their children. It is an experimental study based on the pretest, posttest, follow-up test model with experimental, placebo and control groups. Data were obtained by using the Parent-Child Relationship Scale, mothers' relationships definitions and video-recordings of interviews during which mothers evaluated the training program. As a result of the analyses performed in all three groups, a meaningful improvement was seen in the relationships of experimental group mothers with their children
