Accuracy and congruence of physician and adolescent patient weight-related discussions: Teen CHAT (Communicating health: Analyzing talk).

OBJECTIVE We assessed the accuracy and congruence of recall of weight topics during clinical encounters between adolescent patients with overweight/obesity and physicians (randomized to Motivational Interviewing education vs. control arm). METHODS We audio recorded 357 clinic encounters and coded topics of weight, physical activity (PA), breakfast, and fast food. We assessed recall accuracy/congruence. Generalized estimation equation modeling assessed associations between selected factors and recall accuracy. RESULTS Accuracy for physicians was: weight (90%), PA (88%), breakfast (77%) and fast food (70%). Patient accuracy was: weight (94%), PA (94%), breakfast (73%) and fast food (61%). Physician/patient congruence was: weight (89%), PA (90%), breakfast (71%) and fast food (67%). Use of a reminder report indicating adolescent's weight behaviors in the physician control group resulted in increased adolescent (p = 0.02) and physician accuracy (p = 0.05) for fast food. Adolescents were more likely to recall discussions of fast food (odds ratio, 0.87; 95% CI, 0.77-0.97) as encounter time decreased; male adolescents were less likely to recall breakfast than females (odds ratio, 0.52; 95% CI, 0.28-0.95). CONCLUSION Adolescents and physicians recall weight and PA more often, perhaps indicating greater engagement in these topics. PRACTICE IMPLICATIONS Reminder reports might possibly enhance discussion and recall of diet related messages.
