Behavior codes

Behavior codes are information about the interviewer and respondent’s verbal behaviors during a survey interview’s question–answer process. They are developed and recorded by human coders, not automatically coded by computers. To obtain behavior codes, interviews are audio recorded (generally digitally today, but cassette tapes have been used in the past), transcribed, and then coded by a set of at least two coders to identify relevant behaviors” (Olson & Parkhurst, 2013).
