In this clinical paper, the focus is on the use of questionnaires in family therapy practice. Psychotherapy research has indicated that the quality of the therapeutic relationship is the most robust predictor of therapeutic change. While the therapeutic relationship is even more important in family therapy than in individual therapy, it is also more complex. As will be illustrated in this paper, questionnaires can be useful in clinical practice to deal with the complex alliances in family therapy. In this paper, we will introduce two questionnaires: the Worries Questionnaire and the Dialogical Feedback Questionnaire. As illustrated in detailed case stories, we use these questionnaires in our practice as conversational tools rather than measuring instruments. They serve as the starting point for the therapist’s reflection and for dialogues with family members.
