The CHANGE program: comparing an interactive vs. prescriptive approach to self-management among university students with obesity.

Objective: To assess the effectiveness of 2 self-management (SM) approaches on obesity via a 12-week telephone-based intervention. An interactive motivational interviewing administered via Co-Active Life Coaching (MI-via-CALC) and a structured lifestyle treatment following the LEARN Program for Weight Management were compared. A secondary purpose was to explore the experiences of participants qualitatively.

Methods: University students 18-24 years of age with a body mass index ≥30 kg/m(2) (n = 45) were randomized to either the: 1) MI-via-CALC condition that involved working with a certified Co-Active coach to achieve personal goals through dialogue, or 2) LEARN Program that entailed learning from a trained specialist who provided scripted, education-based lessons pertaining to lifestyle, exercise, attitudes, relationships and nutrition. Food consumption patterns, anthropometric and lipid profiles were examined at baseline, mid- and immediately posttreatment, and 3 and 6 months after the program. A semistructured questionnaire was completed at all follow-ups.

Results: Analyses revealed a significant time effect for weight (p = 0.01) with the LEARN group decreasing more (M = -7.76 lb) than the MI-VIA-CALC group (M = -2.5 lb) between baseline and week 12. MI-via-CALC participants decreased caloric intake more (M = -662.76) than LEARN participants (M = -105.5) during this same period. The MI-via-CALC group focused on self-understanding, and self-responsibility as primary outcomes of their experience; the LEARN group stressed their appreciation of practical knowledge gained.

Conclusions: Both conditions seem similarly effective and are warranted as SM treatments. The best fit and unique contributions of each approach should be considered when working with this population.
