Journal of Clinical Psychology
|January 1, 1981
Summary
This study analyzed changes in coronary heart disease risk factors among 652 high-risk men. Principal component analysis revealed multi-dimensional structures, informing behaviorally oriented risk reduction programs.
Area of Science:
- Cardiology
- Behavioral Science
- Public Health
Background:
- Coronary heart disease (CHD) remains a leading cause of mortality.
- Identifying and modifying risk factors is crucial for prevention.
- Understanding the dynamics of change in multiple risk factors is essential for effective interventions.
Purpose of the Study:
- To investigate the dimensions of change in risk factors for coronary heart disease (CHD).
- To analyze changes in smoking, blood pressure, cholesterol, and psychosocial variables.
- To inform the design of behaviorally oriented risk factor programs.
Main Methods:
- Study conducted on a sample of 652 men at high risk for CHD.
- Principal component analyses were employed to identify underlying structures of change.
- Assessment included smoking status, blood pressure, cholesterol levels, and psychosocial variables.
Main Results:
- Principal component analyses revealed a multi-dimensional structure of change.
- Some identified factors exhibited bipolar characteristics, indicating opposing trends.
- Significant changes were observed across various risk factors and psychosocial variables.
Conclusions:
- The structure of change in CHD risk factors is complex and multi-dimensional.
- Findings support the development of targeted, behaviorally focused interventions.
- Effective risk factor management requires consideration of interconnected variables.
