Abstract/OtherAbstract:
OBJECTIVE: To describe the development, initial application, and evaluation of the Nonverbal Accommodation Analysis System (NAAS). Grounded in Communication Accommodation Theory, this coding system provides a method for analyzing physician and patient nonverbal accommodation behaviors within medical consultations.
METHODS: Video recordings of 45 new visit consultations at a comprehensive cancer center were coded using the NAAS. Inter-rater and intra-rater reliability were assessed. For validation purposes, two independent coders rated all consultations for theoretically related constructs.
RESULTS: The NAAS demonstrated high levels of reliability. Statistically significant correlations were observed across all 10 behavior categories for both inter-rater and intra-rater reliability. Evidence of content and construct validity was also observed.
CONCLUSION: The current study presents the initial application and evaluation of a coding system meant for analysis of the nonverbal behavior of physicians and patients within medical consultations. The results of this initial trial and psychometric evaluation provide evidence of the NAAS as a valid and reliable nonverbal accommodation coding system.
PRACTICE IMPLICATIONS: The NAAS enables researchers to investigate the way in which physicians and patients manage social distance through nonverbal behavior within medical interactions from a theoretically-informed perspective. Such efforts can aid in the development of communication skill interventions.
