简要总结
Approximately one-third of Canadian children have excess weight, putting them at increased risk of type 2 diabetes, cardiovascular disease, bone and joint problems, and some forms of cancer. Because current therapies for managing obesity have modest success, there is a need to develop and test innovative strategies to enhance pediatric weight management. Using a novel interview designed to measure motivation to change lifestyle habits, interviewers will conduct separate and structured 1-on-1 interviews with youth with obesity and parents. By applying principles of motivational interviewing, trained interviewers will ask youth and their parents about their motivation to change lifestyle habits related to diet and physical activity. Subsequently, interview data will be used to examine predictors of clinically-meaningful outcomes over time, including changes in weight status, lifestyle habits, health care utilization, and attrition. The investigators will also measure a number of variables related to weight management, including dietary intake, physical activity, anthropometry, and psychosocial health.
详细描述
The Readiness and Motivation Interview for Families (RMI-Family) was created as a structured interview for assessing youth and parent motivation (and within family member agreement) regarding lifestyle changes in pediatric weight management.
The RMI-Family was modeled on the Readiness and Motivation Interview (RMI), which was developed originally for use in the management of eating disorders (e.g., anorexia nervosa) and emerged as a 'gold standard' approach to assessing treatment motivation in that population. The RMI-Family was based on the tenets of motivational interviewing (MI), a directive, client-centered, and empirically-supported clinical approach to helping individuals resolve ambivalence about change across a range of lifestyle behaviours, including smoking, substance abuse, as well as diet and physical activity.
Participants will be recruited and enrolled into the study after being referred for pediatric weight management within Alberta Health Services, the governmental authority responsible for providing health care in the province of Alberta, Canada. Interviews will be completed following referral and before youth and parents initiative pediatric weight management. Each youth and parent will complete the RMI-Family (interview duration: 60 - 90 minutes) at baseline, 6-, and 12-months post-baseline. Individual (i.e., youth or parent) and family-level (i.e., across youth and parent) responses to interview questions will be scored, as will aspects of interview administration (e.g., fidelity to motivational interviewing tenets).
Families (youth+parent) will also complete the following questionnaires at baseline, 6- and 12-months follow-up:
- Behavior Assessment System for Children-Third Edition (BASC-3)
- Behavior Rating Inventory of Executive Function-Second Edition (BRIEF 2)
- Emotion Regulation Questionnaire (ERQ)
- Coping with Children's Negative Response Scale (CCNES)
- Marlowe-Crowne Social Desirability Scale (MC-SDS)
- Motivation to Change Rulers (Readiness to change lifestyle habits)
- Waterloo Eating Behaviour Questionnaire (WEB-Q)
- Dutch Eating Behaviour Questionnaire (DEBQ)

结局指标
主要结局
Change from baseline psychometric properties at 6- and 12-months
时间窗: Baseline, 6- and 12-months post-baseline
A number of psychometric properties of the Readiness and Motivation Interview for Families (RMI-Family) will be examined, including internal consistency, test-retest reliability, convergent validity, and concurrent validity. Based on data derived from the RMI-Family, we will generate youth, parent, and family (youth-parent) total motivation and motivation sub-scores (5-point Likert scale).
