The article by Lahey (May-June 2009) provided a timely and important review of a growing body of evidence linking the personality trait of neuroticism to a host of health and psychosocial outcomes with public health significance. Lahey (2009) highlighted the links between high neuroticism and mental health, physical health, and quality of life and described the putative genetic and environmental causes of high neuroticism. He recommended screening for high neuroticism and interventions for those presenting this trait in order to reduce health care costs resulting from the associated conditions. We applaud his treatise but note that it failed to address the impact of high neuroticism among parents on their children's long-term psychosocial functioning and mental health. In sum, Lahey (2009) provided a compelling argument for considering interventions for persons with high neuroticism as a public health initiative. We strongly support this call for action, as evidence does show that neuroticism adversely affects not only the individual and his or her social environment but the generations to follow.
