In addition, we used four dyadic IDCS dimensions assessing
the couple as an interactive unit: one positive (interactional
synchrony) and three negative (negative escalation, dominance,
asymmetry in communication repair). Using behavioral cues for
each dimension, trained raters assessed each partner on each individual
dimension and assessed the dyad on each dyadic dimension
using a 9-point scale ranging from 1 (very low) to 5 (moderate) to
9 (very high).
