In this study of 18 female depressed patients and 18 age- and sex-
matched control subjects, the authors examined the relationship between
nonverbal behavior and treatment outcome with amitriptyline. A behavioral
analysis indicated that amitriptyline responders could be differentiated
from nonresponders before drug treatment on the basis of discrete nonverbal
behaviors. Nonresponders showed a high frequency of body-focused
self-adaptors, posture shifts, and pauses and a low frequency of smiles,
while responders displayed long speech pauses and long durations of head
aversion.Abstract Teaser
