Adherence
The Cambridge Index, derived from a short self-report questionnaire, validly ranks individuals into distinct physical activity categories (inactive to active) based on their objectively measured energy expenditure and moderate-to-vigorous physical activity time.
Use a validated short questionnaire to track your general activity level. You don't need to count every step perfectly; the goal is to distinguish between being sedentary, moderately active, or very active. This method is reliable enough for large-scale health studies to rank people accurately.
The EPIC-PAQ is suitable for categorizing European men and women into four distinct categories of overall physical activity... The strongest associations with PAEE and MVPA were observed for the Cambridge index (r = 0.33 and r = 0.25, respectively).
Why this rating
Large sample size (N=1,941), multi-center (10 countries), and use of a robust criterion measure (combined HR and movement sensing).
