Does the John Henryism coping style affect cardiovascular functioning at rest and during stress in normotensive youth?
The John Henryism coping style is associated with adverse resting cardiovascular hemodynamics in youth, particularly among those from lower socioeconomic backgrounds.
Wright et al. (1996) conducted a cross-sectional in normotensive (n=173). John Henryism was evaluated on cardiovascular functioning at rest and during laboratory stressors. High John Henryism scores in youth, especially those from lower socioeconomic backgrounds, were associated with higher resting blood pressure and total peripheral resistance, and lower cardiac index.
