简要总结
The overall objective of this study is to quantify the decision-making process and underlying biases around leisure activity behaviors using the Activity Preference Assessment (APA), a novel psychological task. The investigators plan to validate the APA against objectively measured sedentary and physical activity time, and examine its potential to predict health-related outcomes in children and adolescents. The Shape Up Kids Fitness Ancillary protocol will add exercise testing, cognitive and behavioral measures, accelerometry, and questionnaires to the existing Shape Up Kids primary study dataset.
详细描述
The investigators will enroll 60 boys and girls (50% female) between the ages of 8-17 years into this pilot and feasibility ancillary study. The aims of this study are to validate and test the reliability of the Activity Preference Assessment (APA), as described below.
Aim 1: To examine the convergent validity of the APA against habitual physical and sedentary activity time measured objectively by seven days of accelerometry, as well as leisure activity choices during a 30-minute free-choice play period.
Aim 2: To examine the criterion validity of the APA against concurrent measures of body composition, cardiometabolic health indicators, aerobic fitness, and physical strength.
Aim 3: To measure the test-retest reliability of APA outcomes through repeated measures separated by approximately one week.
Exploratory Aim: To investigate patterns or clusters of activity preferences through exploratory factor analysis of activity liking VAS scores.

结局指标
主要结局
Time 1 APA bias scores
时间窗: Day 0 / Primary Study Visit
Bias scores are calculated from reaction times and choices made during the forced-choice section of the APA. Scores range from -100 to +100, with negative scores indicating a bias towards physical activities, and positive scores indicating a bias towards sedentary activities.
Time 2 APA bias scores
时间窗: 8-21 days after Primary Study Visit
Bias scores are calculated from reaction times and choices made during the forced-choice section of the APA. Scores range from -100 to +100, with negative scores indicating a bias towards physical activities, and positive scores indicating a bias towards sedentary activities.
Habitual physical and sedentary activity
时间窗: 7 days between visits
Physical and sedentary activity time are measured for 24 hours per day over 7 consecutive days, including 2 weekend days, using ActiGraph GT3X+ accelerometers worn on the left mid-axillary line.
Free-choice play period
时间窗: 8-21 days after Primary Study Visit
Children will have 30 minutes to play freely in a room with a variety of sedentary and physical activity choices. Trained observers will record children's activity every 15 seconds.
