Summary

The investigators studied the effect of motivational interviewing (MI) on self-efficacy, health behaviors, and health outcomes in overweight children and adolescents (ages ranging from 10 to 18 years).

Detailed description

One empirically supported intervention with a large evidence base for improving adult outcomes in behavioral health-related disorders is Motivational Interviewing (MI). MI is strongly rooted in the client-centered therapy of Rogers (1951). Its relational stance emphasizes the importance of understanding the client's internal frame of reference and displaying unconditional positive regard for the client. Motivational interviewing can thus be defined as a client-centered, directive method of therapy for enhancing intrinsic motivation to change by exploring and resolving ambivalence. MI manifests through specific strategies, such as reflective listening, summarization, shared decision making, and agenda setting. Adolescent participants exposed to motivational interviewing in conjunction with usual care (diet and exercise program) are expected to endorse greater self-efficacy, report increased engagement in healthy behaviors, demonstrate a decrease in body weight and report improved psychological outcomes. While motivational interviewing has been shown to increase adults' motivation to make healthy behavior changes, few adolescent studies have demonstrated this effect.

Interventions

Type	Name	Description
BEHAVIORAL	Motivational Interviewing (Treatment Group)	Motivational interviewing (MI) can be defined as a client-centered, directive method of therapy for enhancing intrinsic motivation to change by exploring and resolving ambivalence (Miller and Rollnick, 2002). MI manifests through specific strategies, such as reflective listening, summarization, shared decision making, and agenda setting.
BEHAVIORAL	Social Skills Training (Control Group)	Within the social skills training framework, advice is given to clients and sessions are focused on assigning goals for clients to work towards without specific regard for their readiness to change. The intervention is aimed at finding appropriate ways to navigate typical social situations (e.g., how to negotiate with parents).
