After inquiring as to whether respondents had tried any remedies, interviewers asked, "Which of the following treatments have you tried?" "Biofeedback" was one of 15 specific remedies (including "other") listed on a card that interviewers handed to respondents with an affirmative response in TINTREAT. The card prefaced the choices with, "You may choose more than one." The survey form directed interviewers to, "enter all that apply."
