Trauma, Personality, and Behavior: A Longitudinal Study Predicting Adverse Outcomes After Sexual Assault from Personality Prior to the Assault

Exposure to sexual assault results in ongoing harms for women. After an assault, some women engage higher levels of externalizing behaviors, such as drinking problems and drug use, and others experience higher levels of internalizing dysfunction, such as clinical anxiety and clinical depression. In a longitudinal sample of 1929 freshman college women assessed across three time points, I found the following. Pre-assault negative urgency (the tendency to act rashly when distressed) interacted with assault exposure to predict increased subsequent drinking and initiation of drug use. Pre-assault trait anxiety/depression interacted with assault exposure to predict increased subsequent clinical anxiety and depression. There was also the surprising finding that the interaction between assault and trait anxiety/ depression was a protective factor against drinking and drug use. Finally, mean levels of trait negative urgency were significantly higher after an assault, though the same was not true for trait anxiety/depression. Women with different personalities tend to experience different forms of post-assault distress. These results support the development of targeted treatment protocols for trauma specific to personality types

Individual Differences in Personality Predict Externalizing Versus Internalizing Outcomes Following Sexual Assault

For some women, the experience of being sexually assaulted leads to increases in externalizing behaviors, such as problem drinking and drug use; for other women, the experience of being assaulted leads to increases in internalizing distress, such as depression or anxiety. It is possible that preassault personality traits interact with sexual assault to predict externalizing or internalizing distress. We tested whether concurrent relationships among personality, sexual assault, and distress were consistent with such a model. We surveyed 750 women just prior to their freshman year at a large public university. Consistent with our hypotheses, at low levels of negative urgency (the tendency to act rashly when distressed), sexual assault exposure had little relationship to problem drinking and drug use. At high levels of negative urgency, being sexually assaulted was highly associated with those externalizing behaviors. At low levels of internalizing personality traits, being assaulted had little relationship to depression and anxiety symptoms; at high levels of the traits, assault experience was highly related to those symptoms. Personality assessment could lead to more person-specific postassault interventions

An Exploration of Sexual Victimization and Academic Performance Among College Women

The literature has documented the widespread nature of sexual assault victimization among college women. While the aftermath of violence against university women has also received focus, that is, documenting trauma-related sequelae; risk factors; reporting patterns; and legal interventions, the impact on academic performance has not received adequate attention in the literature. The primary purpose of this study was to explore the association of rape and sexual assault with academic performance among college women. Its specific aims included the following: to compare high school and college sexual assault experiences with collegiate grade point averages (GPAs) at key points in time; to examine any differences in GPA by type of sexual assault; to urge researchers studying retention and persistence patterns or sexual assault among college students to ensure that the relationship between the two is included in research designs; and to recommend that academic institutions expand programming on retention to include rape and sexual assault among the risk factors associated with a lack of persistence

Nonsuicidal Self-injury as a Risk Factor for Purging Onset: Negatively Reinforced Behaviours that Reduce Emotional Distress

Both nonsuicidal self-injury (NSSI) and purging behaviour are thought to involve harm to the self. The acquired capability for self-harm model holds that engaging in one self-harming behaviour increases the capability to tolerate harm to the self, thus increasing risk for engaging on other such behaviours. In addition, both behaviours are thought to serve the similar function of relief from distress. We thus tested whether engagement in one of these behaviours predicts the subsequent onset of the other. In a longitudinal design, 1158 first-year college women were assessed for purging and NSSI at two time points. Engagement in NSSI at time 1 predicted the college onset of purging behaviour 9 months later (OR = 2.20, p \u3c .04, CI = 1.07-4.19) beyond prediction from time 1 binge behaviour, and purging behaviour at time 1 predicted the subsequent onset of NSSI (OR = 6.54, p \u3c .01, CI = 1.71-25.04). These findings are consistent with the acquired capability for harm model and with the possibility that the two behaviours serve a similar function

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Negative Urgency and Lack of Perseverance: Identification of Differential Pathways of Onset and Maintenance Risk in the Longitudinal Prediction of Nonsuicidal Self-Injury

Many researchers have identified impulsivity-related personality traits as correlates of and risk factors for nonsuicidal self-injury (NSSI). Using a longitudinal design, we tested the hypothesis that one such trait, negative urgency (the tendency to act rashly when distressed), predicts the onset of NSSI during the first year of college and a different trait, lack of perseverance (the disposition to fail to maintain focus on tasks that are difficult or boring), predicts the maintenance of NSSI during the first year of college. In a sample of n = 1,158 college women (mean age = 18.04, 95% of participants were 18 at Time 1), we found support for these hypotheses. Negative urgency, measured prior to college entry, predicted the onset of NSSI behavior across the first year of college (odds ratio = 1.58). Lack of perseverance predicted the maintenance of NSSI status across the first year of college, controlling for prior NSSI behavior (odds ratio = 1.73). These findings indicate that different impulsivity-related personality traits may play different roles in the risk process for NSSI
