Factor analysis of the English version of the Kategoriensystem für Partnerschaftliche Interaktion [Interaction Coding System].
The Kategoriensystem für Partnerschaftliche Interaktion (KPI), or Interaction Coding System, is an observational coding system used to study behaviors occurring during dyadic interactions. The KPI offers several summary categories (e.g. positive, negative, neutral) to facilitate data analysis, but empirical evidence supporting these rationally derived groupings is lacking. Reported here are the results of a factor analysis of data obtained from 121 spouses or other close relatives of patients with anxiety disorders who participated in dyadic problem-solving interactions with the patients. A three-factor solution accounting for 50% of the variance emerged. The factors were Negativity, Problem-Solving Focus and Emotional Engagement. Confidence in the reliability of the first two factors is bolstered by their similarity to factors detected in prior research on a different coding system, the Marital Interaction Coding System.
