Childhood abuse and sexual revictimization in a female Navy recruit sample

To examine effects of childhood abuse on adult rape, 1,887 female Navy recruits were surveyed. Overall 35% of recruits had been raped and 57% had experienced childhood physical abuse (CPA) and/or childhood sexual abuse (CSA). Controlling for CPA, rape was significantly (4.8 times) more likely among women who had experienced CSA than among women who had not. In contrast, CPA (controlling for CSA) was unrelated to likelihood of adult rape. Alcohol problems and number of sex partners were examined as mediators. Although both variables predicted rape, their effects were independent of the effects of CSA. Finally, despite ethnic group differences in the prevalence of victimization, the predictors of rape did not differ significantly across ethnic groups.

Child sexual abuse and number of sexual partners in young women: the role of abuse severity, coping style, and sexual functioning.

The authors proposed and tested a model describing distinct pathways through which childhood sexual abuse (CSA) may lead to relatively low or high numbers of sexual partners in adulthood. Path analyses were conducted on survey responses of young female US Navy recruits who reported CSA (N=547). Use of avoidant strategies to cope with CSA was expected to produce higher levels of sexual problems and fewer heterosexual sex partners, whereas use of self-destructive coping strategies was expected to result in more dysfunctional sexual behavior and more heterosexual sex partners. As predicted, the effect of CSA on number of sex partners was largely mediated by coping strategies and dysfunctional sexual behavior.

Childhood parenting experiences, intimate partner conflict resolution, and adult risk for child physical abuse.

This study investigated the relationships between conflict resolution tactics experienced during childhood, intimate partner conflict resolution tactics, alcohol problems and adult child physical abuse risk. Participants were 1,544 Navy recruit trainees who volunteered to complete measures of parenting practices and spousal physical violence experienced during their childhood, the conflict resolution techniques used in their intimate relationships, their personal history of alcohol problems, and child physical abuse potential. Regression analyses indicated that the receipt of intimate partner physical violence accounted for the most variance in predicting who would inflict physical violence against an intimate partner; and the infliction of intimate physical violence accounted for the most variance in predicting who would receive physical violence from an intimate partner. Other analyses indicated that among the parent and intimate partner physically violent events, parent-child violence during childhood accounted for the most variance in explaining child abuse risk in females and males, with the infliction of intimate partner violence adding only to the prediction of child abuse risk in females. Analyses also revealed that after the effects of violent experiences were removed, alcohol problems contributed significantly, albeit very modestly, to the prediction of who expressed intimate partner physical violence for males and females, who was physically injured by an intimate partner (in the case of male injury), and who was at risk of child physical abuse for males and females.

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.

Childhood abuse and premilitary sexual assault in male Navy recruits.

Three samples of male U.S. Navy recruits (N = 7,850) were surveyed to determine whether a history of childhood physical abuse (CPA) or childhood sexual abuse (CSA) was predictive of premilitary rape of women and whether these relationships were mediated by alcohol problems and number of sex partners. In the 3 samples, 11.3%, 11.6%, and 9.9% of men reported committing premilitary rape. When demographic factors were controlled for, both CPA and CSA were independently and additively predictive of rape in each sample, with men who experienced both forms of abuse showing the highest risk of committing rape. Additional analyses revealed that alcohol problems and number of sex partners significantly mediated the relationship between childhood abuse (CPA and CSA) and rape perpetration.

Reports of Rape Reperpetration by Newly Enlisted Male Navy Personnel

This study examined the frequency and characteristics of repeated attempted and completed rape (ACR) incidents reported by newly enlisted male navy personnel (N = 1,146) who participated in a longitudinal study during the transition from civilian to military life. Overall, 13% (n = 144) reported engaging in sexual behavior that approximates legal definitions of ACR since the age of 14. Among those men, most (71%) reperpetrated ACR incidents (M = 6.36, SD = 9.55). Demographic variables were unrelated to perpetration history. Regardless of time period, respondents reported perpetrating primarily completed rather than attempted rape, perpetrating multiple ACR incidents rather than a single incident, using substances to incapacitate victims more frequently than force, and knowing their victim rather than targeting a stranger in completed rape incidents.

Risk for Intimate Partner Violence and Child Physical Abuse: Psychosocial Characteristics of Multirisk Male and Female Navy Recruits:

This study examined psychosocial characteristics of individuals at risk for perpetrating both intimate partner violence (IPV risk) and child physical abuse (CPA risk). The sample consisted of 775 female and 592 male Navy recruits. The psychosocial variables assessed included symptoms of dysphoria, posttraumatic stress, self-dysfunction, alcoholrelated problems, and drug use. IPV risk and CPA risk were positively associated with approximately9% of the total sample considered multirisk (i.e., positive for both IPV risk and CPA risk). Results of regression analyses revealed that patterns of predictors (demographic and psychosocial variables) for IPV-risk only and CPA-risk only differed with multirisk individuals characterized by the combined predictors of both types of violence risk. Nearly half (47.2%) of the multirisk individuals were characterized by multiple (i.e., two or more) clinical elevations on the psychosocial characteristics assessed.

Self-definition as a survivor of childhood sexual abuse among navy recruits

This study explored how specific childhood sexual experiences (CSEs) might be related to self-identification as a victim of sexual abuse and to gender differences in self-defined victimization. Hierarchical logistic regression was used to estimate the relationship of demographic and CSE characteristics with self-definitions. The characteristics most strongly associated were threats-force, incest, and younger age at the time of the experience. Men were less likely than were women to acknowledge abuse and to report CSE characteristics indicative of abuse. Women were more likely to identify themselves as victims the more CSEs they reported involving sexual penetration. Finally, in an analysis of familial abuse, men were more likely to define themselves as victims if the perpetrator was also male.

Premilitary Adult Sexual Assault Victimization and Perpetration in a Navy Recruit Sample.

Female (n = 5,226) and male (n = 5,969) U.S. Navy recruits completed a survey assessing their premilitary histories of adult sexual assault (SA), defined as attempted or completed rape since the age of 14. The survey was completed under anonymous or identified conditions. Overall, 39% of women reported premilitary SA victimization and 13% of men admitted premilitary SA perpetration. As predicted, rates were significantly higher in the anonymous than in the identified condition. For the sample of women as a whole, marital status, ethnicity, and family income were associated with SA victimization; for men, only marital status was associated with SA perpetration. Compared to previous college samples, Navy recruits were more likely to have previous SA experience. Given the negative consequences associated with SA victimization and perpetration, the present study reinforces the desirability of developing additional treatment, education, and prevention programs to reduce the occurrence of SA among military recruits.

Perpetration of Severe Intimate Partner Violence: Premilitary and Second Year of Service Rates

A longitudinal design was used to compare rates of severe intimate partner violence (SIPV) perpetration during the year before enlistment and the second year of service in a sample of 542 female and 421 male Navy personnel. Overall, 11% reported perpetration of SIPV during the year before service. Premilitary SIPV perpetration rates were significantly higher for women (20%) than for men (4%). After 2 years of service, the overall percentage reporting past-year perpetration of SIPV increased slightly (14%, compared with a premilitary rate of 11%). The patterns of changes in rates of SIPV perpetration varied for men and women. Across time, SIPV perpetration increased among men (from 4% to 16%) and decreased among women (from 20% to 12%). Respondents who were female, younger, and minority reported higher rates of premilitary SIPV perpetration. No demographic factors were associated with reports of SIPV perpetration during the second year.
