Adherence
A low-intensity motivational interviewing (MI) intervention delivered in primary care produces sustained long-term improvements in walking behavior and cholesterol levels, but fails to maintain reductions in blood pressure, weight, or BMI over 12 months post-intervention.
If you are in primary care and have high cholesterol or want to walk more, a low-intensity counseling approach (Motivational Interviewing) focusing on your own goals can help you maintain increased walking and lower cholesterol for at least a year. However, do not expect this specific low-intensity approach to sustain weight loss or blood pressure reductions without more intensive support.
The present study suggests that a low-intensity MI counselling intervention is effective in bringing about long-term changes in some, but not all, health-related outcomes (walking, cholesterol levels) associated with CVD risk... Post-intervention improvements in other health-related outcomes including blood pressure, weight, and BMI were not maintained.
Why this rating
Randomized controlled trial with 12-month follow-up, though high attrition (94% dropped out between baseline and 6 months) and use of last-observation-carried-forward imputation reduce robustness.
