Faced with the interface between psychotherapeutic intervention and coaching intervention for relational difficulties, this study argues, Christian(pastoral) counselors need to get ready for exploring the interpersonal desires among couples. Christian (pastoral) counselors easily get interested and involved in an in-depth examination of the psychodynamics relating to client’s family of origin. They might understand that one’s relational history in the family of origin has great underlying impact upon one’s current relational difficulties with one’s spouse. Meanwhile, most couples seek counseling they feel that their main problem is communication. If this is the case a first step in counseling is to create more effective communication and start a coaching session for a way of communication. It is in response to these dilemmatic conditions that this research is being done. Author argues that the clinical use of FIRO-B test might be helpful for those who face the dual needs of psycho-dynamic analysis and behavioral coaching. FIRO-B is based on the research of Harvard psychologist William Schutz who identified three dimensions of interpersonal desires: Inclusion (I), Control (C) and Affection (A). Scores are graded from 0-9 in scales of expressed (E) and wanted (W) behavior, which define how much a person expresses to others, and how much he or she wants from others. A case example of couple counseling is used to show how counselors can use the FIRO-B instrument effectively to integrate a psycho-dynamic understanding of human desires with coaching process for behavioral change of interpersonal relationships.
