Hypothesis
The study aims to develop and test the reliability and validity of a self-report instrument to assess the availability and accessibility of physical activity and media equipment in the home environment.
Conclusion
The study provides strong evidence for the reliability and validity of the Physical Activity and Media Inventory (PAMI), suggesting it can effectively assess home equipment related to physical activity and screen media.
Supporting Evidence
- Test-retest reliability was acceptable to strong for all summary variables.
- Reports from participants and research assistants were strongly correlated.
- The PAMI took, on average, 40 minutes to complete.
Takeaway
This study created a tool to help families see what exercise and media equipment they have at home, making it easier to understand how their home can help or hurt their activity levels.
Methodology
The study involved families completing the Physical Activity and Media Inventory (PAMI) twice, once with a research assistant for validity and once independently for reliability.
Potential Biases
Participants may have biased their responses based on their perceptions of accessibility, leading to discrepancies with research assistant observations.
Limitations
The sample was predominantly Caucasian and college-educated, which may not represent the broader population, and the study was limited to specific types of media equipment.
Participant Demographics
Most participants were mothers or female guardians, mean age 38 years, mostly Caucasian (52%), and college educated (65%).
