Previous Day Physical Activity Recall (PDPAR) is a self-report instrument intended to capture the previous day's physical activity of children, specifically after school hours. The PDPAR uses a time-based recall approach by asking the child to recall and record their physical activity from the previous day between 3:00pm and 11:30pm. The time between 3:00pm and 11:30pm is divided into 17 blocks, 30 minutes each. Children are asked to note their specific activity (35 common activities are listed for the child to choose from, each with a numerical code) and the intensity of the activity (very light, light, moderate, or vigorous) per block of time. The physical activity of the child is then determined using the metabolic equivalent, or MET, level.
