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.
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.

| Measure | Description | Time Frame |
|---|---|---|
| Time 1 APA bias scores | 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. | Day 0 / Primary Study Visit |
| Time 2 APA bias scores | 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. | 8-21 days after Primary Study Visit |
| Habitual physical and sedentary activity | 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. | 7 days between visits |
| Free-choice play period | 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. | 8-21 days after Primary Study Visit |
| Measure | Description | Time Frame |
|---|---|---|
| Cardiorespiratory fitness | Cardiorespiratory fitness, or VO2peak in mL/kg/min, is measured using a graded cycle ergometer test to volitional fatigue. | 8-21 days after Primary Study Visit |
| Body composition 1 |
| Measure | Description | Time Frame |
|---|---|---|
| International Sedentary Assessment Tool | Children will fill out questionnaires regarding possible socio-emotional factors that can influence activity choices, including the International Sedentary Assessment Tool. This survey will be scored according to standard published procedures. | 8-21 days after Primary Study Visit |

This study will identify and recruit 60 participants from the Shape Up Kids primary study sample of 360 participants. Ancillary participants will be between the ages of 8-17 years. We will have an even distribution of boys (n=30) and girls (n=30) and aim to have a representative distribution of race.
