Reliability and validity of the Lifestyle Exercise Inventory

Area of Science:

• Health and Physical Activity Measurement
• Psychometrics and Survey Development

Background:

• Assessing physical activity is crucial for public health.
• Existing measures may have limitations in capturing lifestyle exercise patterns.
• The Theoretical Pattern of Physical Activity Model provides a framework for understanding exercise behavior.

Purpose of the Study:

• To develop and validate a new Lifestyle Exercise Inventory (LEI).
• To evaluate the internal reliability and concurrent validity of the LEI.
• To align the inventory with the Theoretical Pattern of Physical Activity Model.

Main Methods:

• Development of the Lifestyle Exercise Inventory.
• Administration of the LEI to 108 women.
• Concurrent assessment using two established physical activity indices.
• Statistical analysis including Cronbach's alpha for reliability and correlation coefficients for validity.

Main Results:

• The LEI exhibited satisfactory internal reliability (Cronbach's alpha = .73).
• Concurrent validity results were equivocal, with correlations of r = .30 and r = .08.
• The inventory aligns with the Theoretical Pattern of Physical Activity Model.

Conclusions:

• The developed Lifestyle Exercise Inventory is a reliable tool for assessing physical activity.
• Further research is recommended to improve the concurrent validity of the LEI.
• The inventory shows potential for use in understanding exercise patterns within the Theoretical Pattern of Physical Activity Model.
