Parameters of Aggressive Behavior in a Treatment-Seeking Sample of Military Personnel: A Secondary Analysis of Three Randomized Controlled Trials of Evidence-Based PTSD Treatments

Aggressive behavior is prevalent among veterans of post-9/11 conflicts who have posttraumatic stress disorder (PTSD). However, little is known about whether PTSD treatments reduce aggression or the direction of the association between changes in PTSD symptoms and aggression in the context of PTSD treatment. We combined data from three clinical trials of evidence-based PTSD treatment in service members (N = 592) to: (1) examine whether PTSD treatment reduces psychological (e.g., verbal behavior) and physical aggression, and; (2) explore temporal associations between aggressive behavior and PTSD. Both psychological (Estimate = -2.20, SE = 0.07) and physical aggression (Estimate = -0.36, SE = 0.05) were significantly reduced from baseline to posttreatment follow-up. Lagged PTSD symptom reduction was not associated with reduced reports of aggression; however, higher baseline PTSD scores were significantly associated with greater reductions in psychological aggression (exclusively; ß = -0.67, 95% CI = -1.05, -0.30, SE = -3.49). Findings reveal that service members receiving PTSD treatment report substantial collateral changes in psychological aggression over time, particularly for participants with greater PTSD symptom severity. Clinicians should consider cotherapies or alternative ways of targeting physical aggression among service members with PTSD and alternative approaches to reduce psychological aggression among service members with relatively low PTSD symptom severity when considering evidence-based PTSD treatments.     

What Makes It Rape? A Lay Theories Approach to Defining Rape Among College Students

Recent changes in the U.S. Justice Department’s definition of rape have renewed its public attention. The present study applied a lay theories approach to the assessment of what college students currently think about rape. Participants (n?=?272) defined rape in their own words; responses were qualitatively analyzed and prominent themes identified. Major themes included the physicality of rape and the victim’s response; minor themes included the potential for victims to be physically harmed and rape’s gendered nature, among others. These findings provide insight into how this demographic conceptualizes and theorizes rape, which is an important step in reducing its prevalence.     

The Dark Side of Helping: Does Returning the Favor from Coworkers Hurt Employee Work Engagement?

This study investigated the potential "dark side" of helping behavior at work -- operationalized as provision of social support to coworkers. Drawing from the emotional contagion literature and Conservation of Resources (COR) theory, we proposed and tested a moderated mediational model to examine the mechanisms by which social support received from one's coworkers contribute to the support recipient's work engagement. Employing data from a 12-week-long weekly diary among 142 acute care nurses, we did not find support for the proposed negative relationship between providing social support to coworkers and support providers' work engagement, nor for the overall mediational effect of the relationship between received coworker support and work engagement through support provision. However, we found that some work contextual factors (i.e., stable social support climates from coworkers and supervisors) moderated the weekly processes through which nurses' repaying social support received from coworkers predicts their subsequent work engagement. Specifically, providing support to coworkers had stronger beneficial effects on providers' engagement when coworker/supervisor support climates were relatively low; support received from coworkers had stronger indirect beneficial effects on nurses' engagement when coworker/supervisor support climates were relatively low. Our study findings highlight the complexity of the relationship between social support dynamics and work engagement, and that emotional contagion and COR theory may be insufficient, on their own, to explain social support dynamics between coworkers. We also discuss implications of the findings for managerial practices related to support dynamics at work.     

Two (Weak) Cheers for Markets in Votes

This paper offers the first moral defense of markets in votes in a democratic electoral system based on majority rule where there are no moral restrictions on how votes can be cast. In Part 1 I outline the type of vote buying that I defend in this paper, and defend my methodological assumption. In Part 2 I criticize Freiman’s arguments for legalizing vote buying (arguments that do not address its morality). In Part 3 I outline and reply to some responses that could be made to my criticisms of Freiman’s arguments. In Part 4 I draw from the flaws in Freiman’s arguments to argue that vote buying is morally permissible and defend these arguments against objections.     

Narcissism and Cardiovascular Reactivity to Rejection Imagery1

This study examined the interactive effects of imagined rejection and narcissism on cardiovascular reactivity (CVR). Participants completed measures of overt narcissism (Narcissistic Personality Inventory, NPI; Raskin & Hall, 1979 ), overt–covert narcissism ( Margolis & Thomas, 1980 ), and trait self‐esteem. They then imagined 2 scenarios culminating in either interpersonal acceptance or rejection. Systolic (SBP) and diastolic blood pressure (DBP) and heart rate (HR) were assessed before, during, and after the imagery. Overt–covert narcissism was positively associated with task increases in SBP and DBP and recovery elevation of HR following rejection, but not acceptance. Similar effects on SBP were found for the Entitlement/Exploitativeness dimension of the NPI. Lower self‐esteem predicted greater task increases in SBP, DBP, and HR across conditions. Implications for health are discussed.
