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'.
