Questionnaire-Description

The Short Questionnaire to Assess Health-Enhancing Physical Activity (SQTAHEPA-11) is a brief questionnaire designed to evaluate health-promoting physical activity in adults. It consists of 11 questions and provides a quick yet reliable assessment of an individual’s level of physical activity in various aspects of daily life, such as exercise, work, transportation, and leisure activities.
The SQTAHEPA-11 covers various categories of activity, such as:
Aerobic exercise
Physical activity at work
Leisure activities
Transportation (e.g., walking, cycling)

Data Analysis and Usage

Data collected from the SQTAHEPA-11 are analyzed to determine an individual’s overall level of physical activity and identify areas that can be improved to promote health. Key analyses include:
Aggregating scores from responses to determine the overall level of physical activity.
Statistical analysis to examine the relationship between physical activity and other factors such as health, well-being, or exercise habits.
The data can be used to monitor physical activity levels in population studies and to evaluate the effectiveness of intervention programs aimed at increasing physical activity.

Purpose

The main goal of the SQTAHEPA-11 is to provide a quick and reliable method for assessing health-enhancing physical activity. The questionnaire helps in:
Understanding individuals’ levels of physical activity.
Identifying areas needing improvement to enhance health and well-being.
Tracking changes in physical activity in intervention studies or health promotion programs.

Calibration

The calibration of the SQTAHEPA-11 involves:
Reliability analysis to ensure the consistency of responses at different time points, typically by calculating Cronbach’s alpha.
Confirmatory factor analysis to establish the validity of the scale’s structure and ensure that the questions accurately measure physical activity.
Cross-validation in various populations to ensure the scale’s generalizability.
