Childhood Abuse and Problematic Alcohol Use in College Females: The Role of Self-compassion

A history of childhood abuse has been consistently linked to heightened risk for subsequent difficulties across the lifespan, including problematic alcohol use and adolescent sexual assault (ASA). Researchers have begun to explore the added role of a lack of self-compassion in the pathway from childhood abuse to later alcohol-related problems. The present study sought to further examine these relationships in a sample at risk for problematic alcohol consumption, undergraduate females (N = 667). It was hypothesized that a history of three forms of childhood abuse (i.e., sexual, emotional, and physical) would directly predict subsequent alcohol problems, as well as indirectly via a history of ASA and low levels of self-compassion. Using path analysis, we found that a history of childhood sexual abuse (B = .24, z = 2.17, p < .05) and childhood physical abuse (B = .16, z = 3.50, p < .05), directly predicted later alcohol problems, whereas a history of childhood emotional abuse (CEA) was indirectly related to alcohol problems via low levels of self-compassion (B = .03, z = 2.18, p < .05). Findings support the emerging literature on the impact of self-compassion in relation to trauma exposure, and suggest that compassion-based skills training may be a worthwhile treatment target for individuals with a history of CEA and comorbid substance use.

Differential Predictors of Transient Stress versus Posttraumatic Stress Disorder: Evaluating Risk Following Targeted Mass Violence

Schools have become a common incident site for targeted mass violence, including mass shootings. Although exposure to mass violence can result in significant distress, most individuals are able to fully recover over time, while a minority develop more pervasive pathology, such as PTSD. The present study investigated how several pre- and posttrauma factors predict posttraumatic stress symptoms (PTSS) in both the acute and distal aftermath of a campus mass shooting using a sample with known levels of pretrauma functioning (N=573). Although the largest proportion of participants evidenced resilience following exposure to the event (46.1%), many reported high rates of PTSS shortly after the shooting (42.1%) and a smaller proportion (11.9%) met criteria for probable PTSD both in the acute and more distal aftermath of the event. While several preshooting factors predicted heightened PTSS after the shooting, prior trauma exposure was the only preshooting variable shown to significantly differentiate between those who experienced transient versus prolonged distress. Among postshooting predictors, individuals reporting greater emotion dysregulation and peritraumatic dissociative experiences were over four times more likely to have elevated PTSS 8months postshooting compared with those reporting less dysregulation and dissociative experiences. Individuals with less exposure to the shooting, fewer prior traumatic experiences, and greater satisfaction with social support were more likely to recover from acute distress. Overall, results suggest that, while pretrauma factors may differentiate between those who are resilient in the aftermath of a mass shooting and those who experience heightened distress, several event-level and posttrauma coping factors help distinguish between those who eventually recover and those whose PTSD symptoms persist over time.

Childhood Sexual Abuse and Later Alcohol-Related Problems: Investigating the Roles of Revictimization, PTSD, and Drinking Motivations Among College Women:

The current study sought to examine whether symptoms of posttraumatic stress disorder (PTSD), adolescent sexual assault (ASA), and drinking motivations (e.g., drinking to regulate emotional experiences) mediate the relationship between a history of childhood sexual abuse (CSA) and subsequent alcohol-related problems among college women. Participants were 579 female students at a Midwestern university. Participants were recruited as part of a larger longitudinal study that investigated risk and resiliency factors related to sexual revictimization. Using a serial mediation model, the current study found that the proposed constructs mediated the relationship between CSA and subsequent alcohol-related problems via two separate paths. In one path, CSA was associated with PTSD, which in turn predicted drinking to regulate emotional experiences, which then was related to alcohol-related problems in adulthood. In the second path, CSA was related to ASA, which in turn predicted drinking to regulate emotional experiences, which then was related to alcohol-related problems in adulthood. These results suggest that individuals with a history of CSA are more likely to experience both revictimization in adolescence and PTSD symptoms in adulthood, which may lead to alcohol-related problems via drinking to regulate emotional experiences. These findings suggest the importance of incorporating skills training in adaptive emotion regulation strategies into treatment for individuals with a history of CSA and ASA.

When Does Child Maltreatment Occur? Daily Variations in Child Maltreatment Among Families Served by the U.S. Air Force Family Advocacy Program

ABSTRACT The current study examined temporal variations in child maltreatment within a U.S. Air Force database. Relative to comparison days, child maltreatment rates generally decreased on weekends, Thanksgiving, and the first days of a month, whereas rates of specific maltreatment types differed on some holidays: Physical abuse decreased on New Years Eve and Memorial Day; neglect decreased on Christmas Eve, Christmas Day, and Independence Day; and emotional abuse decreased on Memorial Day and increased on Super Bowl Sunday. Future research should explore the factors responsible for these patterns of child maltreatment to inform policies aimed at reducing child maltreatment.

Prospective Associations between Emotion Dysregulation and Fear-Potentiated Startle: The Moderating Effect of Respiratory Sinus Arrhythmia

Background: Emotion dysregulation has been implicated in the negative outcomes following trauma exposure. A proposed biomarker of emotion dysregulation, respiratory sinus arrhythmia (RSA), has demonstrated associations with trauma-related phenomena, such as the fear-potentiated startle (FPS) response. The current study aimed to examine the prospective association between emotion dysregulation and RSA and FPS several years following trauma exposure. Methods: Participants were 131 women exposed to a campus mass shooting on February 14, 2008. Pre-shooting emotion dysregulation was assessed in 2006–2008. Startle response, measured by orbicularis oculi electromyography (EMG), and RSA were gathered during an FPS paradigm conducted from 2012 to 2015. Results: No significant associations among emotion dysregulation, RSA, and FPS emerged among the full sample. However, emotion dysregulation predicted FPS during both acquisition (r = 0.40, p < 0.05) and extinction (r = 0.57, p < 0.01) among individuals with high resting RSA. Conclusions: Findings suggest that pre-shooting emotion dysregulation is a potent predictor of FPS several years following potential trauma exposure, and this association varies by RSA level. Results emphasize the importance of examining autonomic regulation in the association between emotion dysregulation and recovery from trauma exposure.
