Insights
Researchers developed new questionnaires to assess children's physical activity, sedentary behaviors, and strengthening activities. These tools were created using qualitative methods to ensure children aged 8-18 understand the questions.
Area of Science:
- Pediatric Health
- Behavioral Science
- Measurement Science
Background:
- Assessing children's activity levels in clinical research is crucial but lacks rigorous tools.
- Existing pediatric self-report measures for activity are scarce.
- Qualitative methods were employed to enhance pediatric activity assessment.
Purpose of the Study:
- To improve pediatric activity self-report measures.
- To develop comprehensive item pools for assessing physical activity, sedentary behavior, and strengthening activities in children.
- To create child-friendly assessment tools.
Main Methods:
- Qualitative methods including conceptual framework development were used.
- Cognitive interviews and comprehensibility reviews were conducted.
- Items were refined to ensure child comprehension.
Main Results:
- 129 unique items were generated across physical activities (80), sedentary behaviors (23), and strengthening activities (26).
- The items were found to be comprehensible for children aged 8 to 18 years.
- Four items were deleted after comprehensibility review.
Conclusions:
- The developed item pools accurately reflect children's understanding of activity concepts.
- These pools will be calibrated using item response theory.
- The goal is to support computer-adaptive testing for self- and proxy-reported outcomes.
Background:
Children's activity level is commonly assessed in clinical research, but rigorous assessment tools for children are scarce. Our objectives were to improve pediatric activity self-report measures using qualitative methods to develop item pools that measure these concepts.
Methods:
On the basis of the items generated from our conceptual framework development, we applied cognitive interviews and comprehensibility reviews to ensure children readily understood the items.
Results:
Our methods resulted in 129 unique items-physical activities (80 items), sedentary behaviors (23 items), and strengthening activities (26 items)-that were comprehensible to children between the ages of 8 and 18 years. Comprehensibility review resulted in the deletion of 4 items.
Conclusions:
The resultant item pools reflect children's experiences and understanding of the concepts of physical activities, sedentary behaviors, and strengthening activities. The item pools will undergo calibration using item response theory to support computer-adaptive test administration of self- and proxy-reported outcomes.
