This study investigated the hypothesis that trait hostility is associated with heightened cardiovascular reactivity to potentially stressful social interactions but not to nonsocial activities in the workplace. Participants were 73 (39 women) New York City traffic enforcement agents (TEAs) who patrol the streets and issue summonses for vehicular and parking violations. During their patrols, TEAs face potentially stressful interactions when they encounter motorists and pedestrians who may be angry about receiving summonses. Mood and ambulatory blood pressure were initially measured when TEAs were recently hired and attending classes at the training academy (Time 1), and were subsequently assessed again once the TEAs began independently patrolling the city streets (Time 2). Random effects regression models yielded a significant interaction of hostility and work activity on ambulatory systolic blood pressure at Time 2. For those high in hostility, but not for those low in hostility, systolic blood pressure levels were higher while interacting with members of the public than during nonsocial work activities. The findings support the notion that situational factors affect the association of hostility to cardiovascular reactivity, and that interpersonal stressors in the workplace elicit cardiovascular activation among those high in hostility. © 2009 American Psychological Association.
