Guide to Scoring Physical Activity Questionnaires

Understanding physical activity levels is essential for improving public health, tracking lifestyle changes, and creating targeted interventions. A physical activity questionnaire (PAQ) provides valuable insights into how often and intensely individuals engage in various activities. However, scoring these questionnaires effectively is crucial to turning raw data into actionable insights.

In this comprehensive guide, we'll walk you through the process of scoring physical activity questionnaires, understanding METs (Metabolic Equivalent of Task) , and how platforms like HeyForm can streamline the process. Whether you’re scoring a global tool like the GPAQ or IPAQ, or designing your own custom form, this guide will ensure you handle the scoring process with confidence and accuracy.

Why Scoring Physical Activity Questionnaires Is Important

Before diving into the specifics, let’s address why scoring PAQs accurately matters:

1. Quantifying Activity Levels: Scoring provides a quantitative measure of physical activity, helping professionals assess whether an individual meets the recommended levels of activity (at least 150 minutes of moderate-intensity aerobic activity per week).
2. Identifying Trends and Gaps: By scoring responses, you can spot trends across various demographic groups, identify sedentary behaviors, and uncover barriers to physical activity.
3. Guiding Health Interventions: With accurate scoring, health interventions can be tailored to specific populations or needs, leading to more effective wellness programs.
4. Tracking Progress Over Time: Scoring also allows you to track changes in physical activity levels, helping assess the effectiveness of health programs or initiatives.

Key Elements in Scoring Physical Activity Questionnaires

Physical activity questionnaires usually ask participants to report on their activities based on frequency, intensity, and duration. To convert these responses into meaningful data, you need to understand how to assign MET values and calculate MET-minutes, which is the standardized way of measuring physical activity intensity.

Here’s how the scoring process works:

1. Categorizing Activities

First, categorize the activities into different levels of intensity: light, moderate, and vigorous. This classification helps assign the appropriate MET value to each activity.

• Light Activities: Activities like walking slowly or light housework. MET values: 2.0-3.0
• Moderate Activities: Activities like brisk walking, cycling at a moderate pace. MET values: 3.5-6.0
• Vigorous Activities: Activities like running, swimming, or intense cycling. MET values: 6.0-12.0+

2. Understanding METs

METs are a standardized way to measure the intensity of physical activity. One MET is the energy expended while at rest. Activities with higher MET values represent more intense activities that burn more calories and require more energy.

Here’s an example:

• Running (6 METs) : Running burns 6 times the calories you would burn while resting.
• Walking (3 METs) : Walking at a moderate pace burns 3 times the calories of resting.

3. Calculating MET-Minutes

Once you’ve assigned MET values, you can calculate MET-minutes—a useful metric to quantify physical activity.

The formula for calculating MET-minutes is:

Total MET-minutes=MET value×Duration (in minutes)×Frequency (days per week)

Total MET-minutes=MET value×Duration (in minutes)×Frequency (days per week)

For example:

• If someone walks for 30 minutes at a moderate intensity (3 METs) 5 times a week, the calculation would look like this:3 (MET value)×30 (minutes)×5 (days)=450 MET-minutes/week3(MET value)×30(minutes)×5(days)=450MET-minutes/week

This means that individual activity contributes 450 MET-minutes of physical activity per week.

Scoring Popular Physical Activity Questionnaires

1. Global Physical Activity Questionnaire (GPAQ)

The GPAQ, developed by the World Health Organization (WHO), is one of the most widely used tools for assessing physical activity. It evaluates three main domains: work, transport, and recreational activities. Here's how to score it:

Scoring GPAQ:

• Work-Related Activity: Multiply the time spent in vigorous, moderate, or walking activities by their respective MET values.
  • Vigorous Work Activity: MET = 8
  • Moderate Work Activity: MET = 4
  • Walking: MET = 3.5
• Transport-Related Activity: Assign MET values to activities like walking or cycling used for commuting.
• Recreational Activity: Calculate MET-minutes for leisure-time activities such as running, weight training, or swimming.

After calculating MET-minutes for each domain, you can sum them up to calculate the total physical activity score for the week.

2. International Physical Activity Questionnaire (IPAQ)

The IPAQ is another popular questionnaire that measures walking, moderate-intensity activities, and vigorous-intensity activities.

Scoring IPAQ:

1. Collect Activity Data: Respondents provide data on frequency (days per week), duration (minutes per day), and intensity (light, moderate, vigorous).
2. Assign MET Values:
   • Walking: MET = 3.3
   • Moderate Activity: MET = 4.0
   • Vigorous Activity: MET = 8.0
3. Calculate MET-Minutes:
   Multiply the MET value for each activity by the reported frequency and duration.

For example, if someone engages in 60 minutes of moderate activity 3 times a week, the calculation would be:

4.0×60×3=720 MET-minutes/week4.0×60×3=720MET-minutes/week

By summing the MET-minutes for walking, moderate, and vigorous activities, you can calculate the total weekly physical activity.
