Adherence
The use of the Behavioral Change Technique 'Feedback on outcomes of behaviour (future)' significantly increases the likelihood of patients taking action to lose weight by 12 months (OR=6.10), although it does not directly correlate with greater mean weight loss.
When giving brief weight loss advice, explicitly schedule a follow-up appointment or promise to provide feedback on the patient's weight in the future. This specific technique ('Feedback on outcomes of behaviour (future)') makes patients significantly more likely to take action (e.g., diet/exercise changes) within a year, even if the total weight loss isn't drastically different from other methods.
The BCT ‘Feedback on outcomes of behaviour (future)’ was associated with an increased likelihood that the patient reported taking action to lose weight by 12 months (OR = 6.10, 95%CI = 1.20, 31.0).
Why this rating
Statistically significant association in a randomized trial, though the effect is on 'action' not 'weight'.

More from this paper
- Brief GP-delivered weight loss advice (approx. 86 seconds) results in a statistically significant mean weight loss of 1.04 kg at 12 months compared to a baseline population average of ~300g, demonstrating that the intervention itself, rather than specific behavioral change techniques (BCTs), drives the outcome.Good
- The Behavioral Change Technique 'Instruction on how to perform behaviour' is associated with weight GAIN (mean weight change +2.53 kg) rather than loss, suggesting it may be counterproductive in brief, opportunistic primary care advice.Good
