Observer reliability of interaction patterns during interviews

"Results of the present study, utilizing one highly experienced observer and another observer with only minimal experience, independently and simultaneously observing the same 17 interviews, indicate that the role of the observer is a highly reliable, almost mechanical one. For the interview as a whole, 8 of the 9 major interaction variables yielded observer reliability coefficients (Pearson rs) above .94. Equally high values were found for many of the five subperiods of the interview, while only one variable, S's adjustment, was found to be unreliable in any subperiod. The (interruption) period showed only moderate (.05 level of confidence) in contrast to the high reliability of the other major variables."
