Stepped-Care in Obesity Treatment: Matching Treatment Intensity to Participant Performance

This investigation examined the effectiveness of a self-help (SH), stepped-care (SC) weight loss program. Based on a failure to achieve pre-assigned weight loss goals, participants were eligible to be stepped-up from a SH program to two levels of treatment intensity (weight loss group [WLG]; individual counseling [IC]) beyond SH. The primary outcome was change in body weight. Fifty-three overweight/obese adults (BMI≥27 kg/m(2); mean BMI of 37.3, SD=6.6, 89% Caucasian, and 77% female) participated in an 18-week weight loss intervention. During several phases of the investigation, those stepped-up to more intensive treatment lost comparable weight to those who were not stepped-up. Nevertheless, by the end of treatment, individuals who remained in SH (M=8.6%) lost a significantly greater percentage of weight than individuals who received SH+IC (M=4.7%;
