This is the second of a pair of studies investigating differences betw
een friends' and acquaintances' conversations. In Study I (Planalp & B
enson, 1992), naive judges were asked to indicate whether they thought
conversations were between friends or acquaintances and why. In Study
II (reported here), the same conversations were analyzed to determine
if the reasons given by judges in Study I did, in fact, discriminate
between friends and acquaintances when coded from the conversations an
d analyzed statistically. Results indicated that the pattern of differ
ences was consistent with Study I, although only a few differences wer
e significant statistically due to low power. Discriminant analyses in
dicated that two variables alone, mutual knowledge and continuity, pre
dicted friends/acquaintances' differences as well as the entire set of
variables and with the same level of accuracy (about 80 percent) as t
he judges in Study I.
