Adherence
The 7-day Physical Activity Recall (PAR) questionnaire provides group-accurate estimates of PAEE comparable to DLW, but fails to accurately estimate absolute PAEE for individuals, overestimating low activity and underestimating high activity.
Use self-reported activity logs to gauge general trends, not precise calorie counts. Be aware that you likely overestimate your effort when you are less active and underestimate it when you are highly active. For precise energy balance tracking, self-report is insufficient.
GoodQualifiesMEDIUM confidence
Although the group average for PAR-PAEE agreed with DLW-PAEE, there were differences in the methods among the subjects.
Why this rating
Validated against DLW, but limited by small sample size and reliance on self-report.
