Jacob Farnsworth's work on his master's thesis has been accepted for publication with Journal of Traumatic Stress and is now available online in advance of publication: Fear of Emotion as a Moderator Between PTSD and Firefighter Social Interactions. (This link may not work properly from some locations, due to limitations in place by the journal publishers.) 

The abstract is as follows: Despite high levels of exposure to stress, questions remain regarding how social interactions and beliefs about emotion interact to influence posttraumatic stress disorder (PTSD) in firefighters. United States urban firefighters (N = 225) completed the Interpersonal Support Evaluation List, the Unsupportive Social Interactions Inventory, the Affective Control Scale, and the Posttraumatic Stress Disorder Checklist. Each independent variable predicted PTSD beyond variance accounted for by demographic variables. Additionally, fear of emotion emerged as the strongest individual predictor of PTSD and a moderator of the relation between social interactions and PTSD symptoms. These findings emphasize the importance of beliefs about emotion both in how these beliefs might influence the expression of PTSD symptoms, and in how the social networks of trauma survivors might buffer distress.
