Reactions to trauma research among women recently exposed to a campus shooting.

Subjective and objective reactions to writing and reading a narrative of their experiences after having been recently exposed to a campus shooting were examined in 58 women. Posttraumatic stress, depression, anxiety symptoms, and physical exposure to the shooting were considered in relation to laboratory indices. The latter used a multimethod approach to index distress; these included subjective (self-report) and objective (heart rate, skin conductance, and cortisol) components. Consistent with prior research, reports of symptoms were significantly positively correlated with subjective distress (r ranged from .35 to .45), but only posttraumatic stress symptoms uniquely predicted subjective distress in regression analyses (partial r = .33). Objective distress, however, was not significantly related to any participant measure. Finally, a clear majority (85%) of participants reported they would participate in the study again. Points of convergence and divergence with prior studies are discussed.

Evaluation of a sexual assault education/prevention program for female U.S. Navy personnel.

The U.S. Navy Sexual Assault Intervention Training (SAIT) program for women was evaluated in a randomized clinical trial. The SAIT uses multiple presentation modalities (lecture, slides, discussion, film) to provide information related to sexual assault, including risk factors, consequences, prevention, and relevant military regulations. Female personnel who had completed basic training (N = 550) participated in the SAIT or a Comparison condition, and then completed measures of rape knowledge, empathy for rape victims, and acceptance of rape myths (false beliefs about rape justifying sexual violence). Results showed that the SAIT increased factual knowledge about rape. In addition, the SAIT increased empathy with rape victims in some groups of women. However, the program did not reduce women's rape myth acceptance. Given the enormity of the problem of sexual assault and these promising initial findings, additional research on the efficacy of the SAIT is clearly warranted.

Evaluation of a sexual assault education/prevention program for male U.S. Navy personnel.

A randomized clinical trial was conducted to evaluate the effectiveness of the Navy Sexual Assault Intervention Training (SAIT) program for men. A four-group Solomon design was used to control for possible pretest sensitization effects. Male Navy personnel (N = 1,505) were assessed for rape knowledge, rape myth acceptance (two scales), and rape empathy after participating in the SAIT program or viewing an educational video about HIV/AIDS (comparison condition). The SAIT program was found to be effective in increasing rape knowledge, reducing rape myth acceptance, and increasing empathy for rape victims. As expected, men who had exhibited previous coercive sexual behavior, compared with those who had not, reported lower levels of knowledge, higher levels of rape myth acceptance, and less rape empathy. However, the SAIT program was generally effective in changing men's knowledge, beliefs, and feelings on the key measures, regardless of participants' histories of coercive sexual behavior.

Substantiation of spouse and child maltreatment reports as a function of referral source and maltreatment type.

Substantiation rates for alleged incidents of spouse (N = 33,787) and child (N = 31,986) maltreatment reported to the U.S. Air Force (AF) Family Advocacy Program between 2000 and 2007 were examined. For spouse maltreatment, physical abuse and multiple forms of maltreatment were most likely to be substantiated and neglect was least likely to be substantiated. For child maltreatment, emotional abuse was most likely to be substantiated and physical abuse was least likely to be substantiated. Substantiation rates were higher for referrals by military professionals than for referrals by civilian professionals or nonprofessionals; considerable variation in substantiation rates within each of these categories also was observed. Overall, AF substantiation rates were higher for spouse than for child maltreatment, and substantiation rates for child maltreatment were higher in the AF than in the general U.S. population. Substantiation rates have declined over time in both the AF and the United States.

Suspected child and spouse maltreatment referral sources: who reports child and spouse maltreatment to the Air Force Family Advocacy Program?

The present study describes the sources of Air Force (AF) Family Advocacy Program referrals (N = 42,389) for child and spouse maltreatment between 2000 and 2004. Sources of referrals were stable over time, with military sources accounting for the majority of both child and spouse referrals. Most (85%) of spouse maltreatment referrals came from AF law enforcement, medical and psychological staff, command, and victim self-referrals. For child maltreatment, most referrals (71%) were from law enforcement, medical and psychological staff, command, social services, and friends or relatives. Differences in the sources of referrals across different types of maltreatment were greater for child than for spouse maltreatment. Comparison of the sources of child maltreatment referrals in the AF and U.S. samples revealed substantial similarity. However, self-referrals by the victim or offender were more common in the Air Force, whereas referrals by friends and relatives or by school or child care staff were more common in the U.S. sample.

Sexual assault survivors' reactions to a thought suppression paradigm.

Trauma survivors may experience harm from participating in research on sensitive topics. The current study assessed reactions of sexual assault survivors with and without symptoms of post-traumatic stress disorder (PTSD) immediately following an experimental thought suppression task and at a 2- to 4-week follow-up period, by asking open-ended questions regarding thoughts about the experiment, feelings following the experiment, and willingness to participate in similar experiments. At both time periods, most participants reported neutral/positive thoughts (e.g., "interesting") and feelings (e.g., "fine, good") and indicated that they would participate in a similar study. Findings suggest that the majority of sexual assault survivors were not harmed in the short- or long-term by participation in a thought suppression paradigm in which the target of suppression/expression was their own trauma.

A comparison of methods for collecting self-report data on sensitive topics.

Insufficient attention has been paid to whether disclosure rates of sensitive or stigmatizing information vary as a function of method of inquiry. Methods vary both in terms of the anonymity afforded the participant and the opportunity to make a connection with the researcher, both of which might affect participants' willingness to disclose such information. In this investigation, 215 undergraduate students were randomly assigned to complete identical questionnaires using one of the three most common methods of data collection (in-person interview, telephone interview, and paper-and-pencil questionnaire) or an automated telephonic data collection (ATDC) system. Questions on six topic areas of increasing social sensitivity (study habits, substance use, physical and sexual aggression, victimization and perpetration) were included. The results indicated that there were no differences in disclosure rates due to methods and no method by topic interaction, but the two telephonic methods both produced significantly higher participation rates than the two other methods. The results suggest that, at least for a college student sample, an automated telephonic system produces data comparable to that of more traditional methods, while offering greater convenience, economy, and participation.

Effects of method on participants and disclosure rates in research on sensitive topics.

This study replicates and extends the research of Rosenbaum, Rabenhorst, Reddy, Fleming, and Howells, which also appears in this special issue. Responses from 398 randomly assigned participants regarding differentially sensitive topics were collected via four methods of data collection: written questionnaires, face-to-face interviews, telephone interviews, and an automated telephonic data collection system (ATDC). Several significant differences in data collection methodology and topic area were found, including greater disclosure of sensitive information via the ATDC system than via face-to-face and paper-and-pencil conditions. Participants who were assigned to the ATDC condition felt significantly more comfortable answering questions compared to those in the face-to-face interview condition. Participants in the telephone interview condition reported answering significantly more carefully than participants answering via written questionnaire. Taken together, the results of this study and the previous one it replicates suggest that the ATDC produces disclosure rates that are at least equivalent to, if not greater than, those generated using traditional methods for collecting sensitive data.

Predictors of expressive writing content and posttraumatic stress following a mass shooting.

This study examined relations among experiential avoidance, state dissociation during writing, cognitive-emotional processing, and posttraumatic stress in the context of an expressive writing task among 58 undergraduate females who were students at a large midwestern university that had recently experienced a mass shooting. Experiential avoidance significantly predicted reported suppression during the writing task. Additionally, posttraumatic stress symptoms (PTSS) at the time of the writing task were significantly associated with state dissociation, suppression, and the use of positive emotion words during the writing. Finally, at the zero-order level, prospective PTSS were associated with state dissociation and suppression during the earlier writing task. However, in a full regression model, only experiential avoidance and PTSS at the time of the writing task significantly predicted prospective PTSS. Supplemental analyses suggest processes may operate differently across levels of exposure. Findings from the present study provide further support for the role of experiential avoidance, state dissociation during writing, and cognitive-emotional processing in predicting PTSS. Additionally, experiential avoidance may play an important role in how individuals use cognitive-emotional processing to narrate a traumatic event.

Child maltreatment among U.S. Air Force parents deployed in support of Operation Iraqi Freedom/Operation Enduring Freedom.

This study examined child maltreatment perpetration among 99,697 active-duty U.S. Air Force parents who completed a combat deployment. Using the deploying parent as the unit of analysis, we analyzed whether child maltreatment rates increased postdeployement relative to predeployment. These analyses extend previous research that used aggregate data and extend our previous work that used data from the same period but used the victim as the unit of analysis and included only deploying parents who engaged in child maltreatment. In this study, 2% (n = 1,746) of deploying parents perpetrated child maltreatment during the study period. Although no overall differences were found in child maltreatment rates postdeployment compared to predeployment, several maltreatment-related characteristics qualified this finding. Rates for emotional abuse and mild maltreatment were lower following deployment, whereas child maltreatment rates for severe maltreatment were higher following deployment. The finding that rates of severe child maltreatment, including incidents involving alcohol use, were higher postdeployment suggests a need for additional support services for parents following their return from combat deployment, with a focus on returning parents who have an alcohol use problem.

Characteristics associated with incidents of family maltreatment among United States Air Force families.

From 2002 until 2007, the United States Air Force (USAF) revised the process of determining whether incidents of suspected family maltreatment met the criteria for maltreatment. In this study, all reported child maltreatment and partner abuse incidents in the USAF from January 2008 to July 2011 were examined to determine the extent to which characteristics of victims, offenders, and incidents affected whether incidents were determined to have met criteria for maltreatment. For both child maltreatment and partner abuse, alleged incidents in which offenders used substances and more severe incidents were more likely to have met maltreatment criteria than alleged incidents that did not involve offender substance use and less severe incidents. However, characteristics of the persons involved (e.g., age, gender, military status) were generally unassociated with an incident meeting criteria. Consistent with the goals of the criteria revisions, these results suggest that the current USAF criteria are associated with incident characteristics and not with demographic characteristics of the persons involved in the incident.

What difference does a day make? Examining temporal variations in partner maltreatment.

Routine activities (RA) theory posits that changes in people's typical daily activities covary with increases or decreases in criminal behaviors, including, but not limited to, partner maltreatment. Using a large clinical database, we examined temporal variations among 24,460 incidents of confirmed partner maltreatment across an 11-year period within the U.S. Air Force (USAF). Specifically, we created regression models that predicted the number of partner maltreatment incidents per day. In addition to several control variables, we coded temporal variables for days of the week, month, year, and several significant days (e.g., holidays, Super Bowl Sunday), which allowed us to examine the independent influence of these variables on partner maltreatment prevalence. While accounting for the influence of all other study variables, we observed significant increases in partner maltreatment for weekend days, New Year's Day, Independence Day, and Super Bowl Sunday. Similar results were found for partner maltreatment incidents involving offender alcohol/drug use. Furthermore, the proportion of incidents involving offender alcohol/drug use increased on New Year's Day and Independence Day. Consistent with RA theory and data from civilian samples, the current results indicate that certain days are associated with increased incidents of partner maltreatment within the USAF. These findings should be used to inform future preventive efforts.

Spouse abuse among United States Air Force personnel who deployed in support of Operation Iraqi Freedom/Operation Enduring Freedom.

The authors examined spouse abuse perpetration among all married U.S. Air Force personnel who deployed in support of Operation Iraqi Freedom/Operation Enduring Freedom. Using Poisson and conditional Poisson regression, they compared rates of spouse abuse perpetration predeployment and postdeployment in the population of married U.S. Air Force personnel who had a combat-related deployment between October 1, 2001 and October 31, 2008 (N = 156,296). Just over 2% (n = 3,524) of deployers perpetrated at least one substantiated incident of spouse physical or emotional abuse within the 308,197,653 days at risk for abuse during the study period. Male deployers perpetrated spouse abuse at approximately twice the rate of female deployers. Regarding changes in rates of spouse abuse perpetration postdeployment versus predeployment among all deployers, the authors found no differences overall; however, several deployer and incident-related characteristics moderated this effect. Rates of emotional abuse, mild abuse, and abuse not involving alcohol were significantly lower postdeployment, whereas rates of moderate/severe abuse and abuse involving alcohol were significantly higher postdeployment. Although the majority of U.S. Air Force deployers did not perpetrate any substantiated incidents of spouse abuse, there was variability in the impact of deployment on spouse abuse rates before versus after deployment. The finding that rates of moderate/severe spouse abuse incidents involving alcohol were higher postdeployment suggests a need for focused prevention/intervention efforts.

Effects of combat deployment on risky and self-destructive behavior among active duty military personnel.

Although research has documented negative effects of combat deployment on mental health, few studies have examined whether deployment increases risky or self-destructive behavior. The present study addressed this issue. In addition, we examined whether deployment effects on risky behavior varied depending on history of pre-deployment risky behavior, and assessed whether psychiatric conditions mediated effects of deployment on risky behavior. In an anonymous survey, active duty members of the U.S. Marine Corps and U.S. Navy (N = 2116) described their deployment experiences and their participation in risky recreational activities, unprotected sex, illegal drug use, self-injurious behavior, and suicide attempts during three time frames (civilian, military pre-deployment, and military post-deployment). Respondents also reported whether they had problems with depression, anxiety, or PTSD during the same three time frames. Results revealed that risky behavior was much more common in civilian than in military life, with personnel who had not deployed, compared to those who had deployed, reporting more risky behavior and more psychiatric problems as civilians. For the current time period, in contrast, personnel who had deployed (versus never deployed) were significantly more likely to report both risky behavior and psychiatric problems. Importantly, deployment was associated with increases in risky behavior only for personnel with a pre-deployment history of engaging in risky behavior. Although psychiatric conditions were associated with higher levels of risky behavior, psychiatric problems did not mediate associations between deployment and risky behavior. Implications for understanding effects of combat deployment on active duty personnel and directions for future research are discussed.

Event-related potentials: search for positive and negative child-related schemata in individuals at low and high risk for child physical abuse.

OBJECTIVE: The present investigation used event-related potentials (ERPs, N400 and N300) to determine the extent to which individuals at low and high risk for child physical abuse (CPA) have pre-existing positive and negative child-related schemata that can be automatically activated by ambiguous child stimuli. METHODS: ERP data were obtained from individuals at low (n=13) and high risk (n=12) for CPA and used in a procedure check, from which a sub-group of low-risk (n=7) and high-risk (n=7) individuals were selected for inclusion in the main study. ERP data were collected during the presentation of a priming paradigm consisting of non-child pictures (primes) and congruent and incongruent word descriptors (targets). ERP data also were collected during a second priming paradigm consisting of ambiguous child pictures (primes) and positive and negative word descriptors (targets). Data from this second paradigm were used to test the hypothesis that low-risk and high-risk individuals' putative pre-existing child-related schemata (i.e., positive schemata in low-risk individuals and negative schemata in high-risk individuals) provide a context that influences whether targets (positive or negative word descriptors) are congruent or incongruent with ambiguous child picture primes. RESULTS: Analyses revealed the expected larger N400 waves in response to non-child picture, incongruent word pairs. There were no N400 differences between risk groups nor were there any risk group interactions, indicating that all participants responded in a similar manner to the non-child picture, congruent/incongruent word presentations. However, when ambiguous child picture primes were used with positive and negative word descriptors, low-risk individuals showed greater N400 and N300 responses to negative, relative to positive, word descriptors; whereas high-risk individuals showed no ERP differences with respect to positive and negative word descriptors. CONCLUSIONS: ERP evidence supports the view that low-risk individuals have greater accessibility to pre-existing positive (relative to negative) child-related schemata, which may reduce the likelihood of negative child-related evaluations. In contrast, high-risk individuals have pre-existing positive and negative child-related schemata that are equally accessible. Hence, high-risk, relative to low-risk, individuals appear to have greater accessibility to negative child-related schemata that may increase the likelihood of negative child-related evaluations and attributions that have been linked to CPA risk.

Do trauma symptoms mediate the relationship between childhood physical abuse and adult child abuse risk?

OBJECTIVE: Although the intergenerational transmission of family violence has been well documented, the mechanisms responsible for this effect have not been fully determined. The present study examined whether trauma symptoms mediate the relationship between a childhood history of child physical abuse (CPA) and adult CPA risk, and whether any such mediation was similar for women and men. METHOD: Female and male US Navy (USN) recruits (N=5,394) and college students (N=716) completed self-report measures of their history of child abuse (i.e., CPA and child sexual abuse [CSA]), exposure to intimate partner violence (IPV), current trauma symptoms, and adult CPA risk. RESULTS: As expected, there was a strong association between a childhood history of CPA and adult CPA risk. This association was significant even after controlling for demographic variables and childhood exposure to other forms of violence (CSA and IPV), and the strength of the relationship did not vary depending on demographics or exposure to other forms of violence. However, the association between a history of CPA and adult risk of CPA was stronger for individuals high in defensive avoidance compared to those low in defensive avoidance. The association between a history of CPA and adult CPA risk was largely, although not entirely, mediated by psychological trauma symptoms. Mediation was observed for both women and men in both the USN and college samples. CONCLUSIONS: Trauma symptoms associated with a history of CPA accounted for a substantial part of the relationship between a history of CPA and adult CPA risk in both women and men. PRACTICE IMPLICATIONS: To the extent that trauma symptoms are a mechanism by which the intergenerational transmission of child abuse occurs, intervening to reduce trauma symptoms in CPA victims has the potential of reducing their risk of continuing the cycle of violence.
