Abstract

This study examined whether providing additional support to individuals with poor initial weight loss improves 12-week outcomes. Participants were randomized to a 12-week internet-delivered behavioral weight loss program (IBWL; n = 50) or the identical internet program plus the possibility of extra support (IBWL + ES; n = 50). IBWL + ES participants losing <2.3 % at Week 4 (early non-responders; n = 12) received one individual meeting and two follow-up phone calls with an interventionist, and were compared to IBWL ‘early non-responders’ who did not receive extra support (n = 21), and to ‘early responders’ in both treatment arms (i.e., 4-week weight loss ≥2.3 %; n = 59). IBWL + ES early non-responders had greater program adherence (p’s < 0.055) and lost twice as much weight (p = 0.036) compared to IBWL early non-responders. Program adherence did not differ between early responders and IBWL + ES early non-responders. However, 12-week weight loss was greater in the early responders compared to both early non-responder groups (p’s > 0.05). Providing additional intervention to early non-responders in an Internet program improves treatment outcomes.
