Shared genetic influences on youth anger and stress are hypothesis-generating; prospective studies needed before any clinical consideration.
Observational (n=1,038)
Psychosocial factors such as anger expression and perceived stressful life events have moderate genetic and substantial environmental influences in youth, with their association largely driven by common genes.
Wang et al. (2005) conducted an observational in Stress and coping styles (n=1,038). Genetic and environmental factors was evaluated on Variation and covariation of perceived stressful life events, anger expression, and John Henryism. Genetic and environmental factors influenced coping styles and life events, with 61% of the correlation (r=0.28) between anger expression and life events mediated by common genes.
