title: "Teens Talk Healthy Weight": the impact of a motivational digital video disc on parental knowledge of obesity-related diseases in an adolescent clinic.
abstract: The purpose of the study was to investigate the impact of a 7-minute educational and motivational weight-management digital video disc (DVD) that uses real patient/parent testimonials and provider-patient interactions, on adolescent and parent knowledge of obesity-related diseases; readiness, motivation, and self-efficacy to lose weight; connectedness to care provider; and likelihood of return to clinic for follow-up care. A randomized controlled trial was conducted among 40 overweight/obese adolescent participants (22.5% male, 77.5% female, mean age=15.43 years) and their parents (n=38) who visited a referral-only adolescent clinic for the first time from October 2009 to March 2010. Adolescents were randomly assigned by a research assistant to standard care alone or standard care plus DVD. Standard care (protocol-driven medical and nutritional assessment and counseling) was provided to all adolescents by a registered dietitian nutritionist and physician or nurse practitioner. Adolescents in the intervention group also viewed the DVD. Adolescents and parents completed assessments pre- and post-clinic visit. Repeated measures analysis of covariance was used to evaluate group differences, while controlling for race/ethnicity and age. Parents who viewed the DVD experienced greater improvements in obesity-related disease knowledge than parents who did not view the DVD. Adolescents in both groups improved on measures of motivation to lose weight and dieting self-efficacy, based on pre and post-test questionnaires. A 7-minute educational and motivational DVD helped improve parent knowledge, but was not more powerful than standard care alone in changing other weight-related outcomes in this adolescent clinic. Because it led to increased parental knowledge, incorporating the DVD into clinical practice could also allow more time for health providers to focus on specific obesity-related treatment/education. Future research might examine whether the DVD has more utility in different settings, such as primary care.
