Hypothesis

The study aims to investigate the utility of the Theory of Planned Behavior in explaining aerobic physical activity and resistance training among adults with type 2 diabetes.

Conclusion

The study suggests that the Theory of Planned Behavior can help guide the development of effective physical activity interventions for adults with type 2 diabetes.

Supporting Evidence

  • TPB explained 10% of the variance for aerobic physical activity and 8% for resistance training.
  • 39% of the variance in aerobic PA intentions and 45% in resistance training intentions were explained by TPB.
  • Only 23.5% of participants met the guidelines for aerobic PA, and 17% for resistance training.

Takeaway

This study looks at how people's thoughts and feelings about exercise can help them be more active, especially for those with diabetes.

Methodology

Participants completed self-report measures of the Theory of Planned Behavior constructs and were followed up after three months to assess their physical activity.

Potential Biases

Self-reporting may lead to recall bias and social desirability bias.

Limitations

The study relied on self-reported measures, which can introduce biases, and had a relatively low response rate.

Participant Demographics

The sample consisted of adults with type 2 diabetes, predominantly over 60 years old, with a majority being male.
