This study shows a hostility reduction program significantly decreased anger and cynicism in high-hostile males. The intervention may lower coronary heart disease (CHD) risk factors and mortality predictors.

Area of Science:

  • Psychology
  • Cardiology
  • Behavioral Medicine

Background:

  • Hostility is a significant independent risk factor for coronary heart disease (CHD).
  • Specific hostility subscales, such as Barefoot's refined Ho, are more potent predictors of CHD and mortality than global hostility measures.
  • Developing interventions to modify CHD-predictive hostility components is crucial for cardiovascular health.

Purpose of the Study:

  • To develop and test an intervention aimed at reducing hostility components that predict CHD.
  • To evaluate the efficacy of a hostility-reduction treatment program in high-hostile males.
  • To assess the impact of the intervention on anger, antagonism, and cynicism.

Main Methods:

  • Twenty-two healthy, high-hostile males were recruited and matched on age and hostility levels.

  • Participants were randomly assigned to either an experimental hostility-reduction treatment group or an information-control group.
  • The experimental group underwent eight weekly 90-minute sessions focused on altering antagonism, cynicism, and anger reactions.

    • Main Results:

    • The hostility-reduction treatment significantly improved observed Anger-Out scores, accounting for 28% of the variance after controlling for pretreatment levels.
    • The treatment also significantly improved Barefoot's refined Ho scores, accounting for 19% of the variance.
    • These improvements suggest the intervention effectively reduces CHD-predictive and mortality-predictive hostility levels.

    Conclusions:

    • The developed hostility-reduction intervention shows promise in mitigating CHD-predictive and mortality-predictive hostility.
    • The findings suggest potential clinical significance for managing cardiovascular risk factors.
    • Further large-scale and long-term trials are recommended to validate these results and explore broader clinical applications.
