Adherence
High adherence to the YDPP intervention (9 or more lessons) results in significantly greater weight loss (5.3 kg) compared to standard care, suggesting that the dose of the intervention directly correlates with the magnitude of weight loss.
If you can commit to attending most of the YDPP sessions (at least 9 out of 16), you can expect to lose about 12 pounds (5.3 kg) over a year. This is significantly more than what you would lose with just general advice. The key is consistency in attending the weekly group sessions.
GoodSupportsHIGH confidence
In instrumental variable analyses, persons attending 9 or more lessons had a 5.3-kilogram (95% CI = 2.8, 7.9 kg) greater weight loss than did those with standard care alone.
Why this rating
Instrumental variable analysis reduces selection bias, strengthening the causal inference for adherers.
