Data from 231 pharmacist-patient encounters in 12 community pharmacies
were analyzed to test if there were differences in components of comm
unication under conditions of role congruence and role incongruence. R
elations among patient age, new or refill prescription status, and rol
e congruence/incongruence were explored to help understand why role in
congruence might occur between pharmacists and patients. Average lengt
h and content of communication for encounters with interrole congruenc
e were 74 sec and 4.1 types of information, respectively, compared wit
h only 36 sec and 3.0 types of information for those with interrole in
congruence, t(229) = 3.5, p < .05 and t(229) = 3.7, p < .05, for each
respective comparison. Interrole incongruence was more common between
pharmacists and older patients. When patient age was controlled, there
was no relation between prescription status and role congruence/incon
gruence. Older patients may prefer to talk about medications only with
their physician and not their pharmacist, which might account for old
er people comprising the incongruence group.
