(it's added, some are reverse coded). To determine the family's mean RS for each subscale, average the subscale raw scores for all members of that family. Relationship-Oriented Families. These families cannot be categorized as personal growth-oriented and have at least one elevated subscale within the relationship domain. Relationship-oriented families include: Ø Support-oriented families (15.3 percent; cohesion or expressiveness or both ≥ 60 and either cohesion or expressiveness ≥ conflict) Ø Conflict-oriented families (5.2 percent; conflict ≥ 60)

The CCAT-PF is an 18-item questionnaire that assesses congruence in patient-family caregiver communication; there are parallel versions of the instrument for patients and family members.
