Cynical hostility and vulnerability to disease: social support, life stress, and physiological response to conflict
Insights
High hostility scores are linked to greater anger, cynicism, and physiological stress responses. This suggests cynical hostility may increase disease risk through stress and poor social support.
Area of Science:
- Psychology
- Health Psychology
- Behavioral Medicine
Background:
- Previous research links high scores on the Cook and Medley Hostility (Ho) scale to increased risk of coronary heart disease.
- The construct assessed by the Ho scale requires further clarification regarding its relationship with physiological and psychosocial factors.
Purpose of the Study:
- To examine the construct validity of the Ho scale.
- To investigate physiological reactivity during interpersonal conflict in high- and low-Ho groups.
- To assess the psychosocial profile associated with high hostility.
Main Methods:
- Selection of extremely high and low Ho groups from male undergraduates.
- Assessment of anger proneness, interpersonal attitudes, and psychosocial factors.
- Measurement of physiological reactivity (diastolic blood pressure) during role-played interpersonal conflict.
Main Results:
- High-Ho participants reported greater anger proneness and cynicism.
- High-Ho individuals displayed more hostile behavior and less friendly behavior during conflict scenarios.
- High-Ho individuals exhibited greater diastolic blood pressure reactivity during interpersonal conflict.
- The high-Ho group reported less social support and more negative life events and daily irritants.
Conclusions:
- The Ho scale effectively measures cynical hostility.
- Excessive physiological reactivity and a stressful, unsupportive social network may mediate the link between hostility and disease.
- Findings support the hypothesis that cynical hostility contributes to adverse health outcomes.
Abstract:
Previous research has indicated that high scores on the Cook and Medley Hostility (Ho) scale are associated with increased risk of coronary heart disease and other illness. Our study attempts to clarify this relationship by providing additional evidence concerning the construct assessed by the Ho scale, examining the level of physiological reactivity during interpersonal conflict in high- and low-Ho groups, and assessing the psychosocial profile associated with this characteristic. Extremely high and low Ho groups were selected from a pool of male undergraduates. Consistent with previous findings, high-Ho participants reported greater anger proneness and a more cynical, disparaging view of others than did low-Ho participants. The high-Ho group also tended to be more hostile and less friendly during role-played interactions involving high and low levels of interpersonal conflict, respectively. High-Ho persons also displayed greater diastolic blood pressure reactivity during interpersonal conflict. Finally, the high-Ho group reported less social support and more negative life events and daily irritants then did the low-Ho group. These results support the interpretation of the Ho scale as a measure of cynical hostility and are consistent with the hypothesis that it is related to disease by way of excessive physiological reactivity and a generally stressful, unsupportive social network.
