title: Assessing readiness for change in adolescents with eating disorders.
abstract: The Readiness and Motivation Interview (RMI) is a semistructured interview measure of readiness and motivation to change that can be used for all eating disorder diagnoses. The RMI has demonstrated excellent psychometric properties and has both clinical and predictive utility in adult samples. This study examined the psychometric properties of the RMI in a younger population, namely, 12- to 18-year-old girls with eating disorders. Study participants (N = 65) completed the RMI and measures of convergent, discriminant, and criterion validity. Adolescents with eating disorders were able to conceptualize and articulate their readiness for change and to report the extent to which change efforts were for themselves versus for others. RMI readiness profiles across eating disorder symptom domains in adolescents were comparable to those in adults, with higher reported readiness to change binge eating than to change dietary restriction or compensatory strategies. Differences in internal consistency between adult and adolescent samples are discussed. Interviewing adolescents early in treatment about readiness may assist clinicians in forming an alliance with this difficult-to-engage population, while also providing valuable information for treatment planning.
