Prevalence and risk factors of depression in U.S. adults post mass shootings: evidence from population-based surveys of multiple communities.

OBJECTIVES: Mass violence incidents (MVIs) involving firearms, commonly referred to as "mass shootings" have become increasingly frequent in the United States. These shootings often result in immediate casualties and have far-reaching psychological impacts on survivors, witnesses, and the broader community. This study aimed to assess the prevalence and risk factors of depression within affected communities. STUDY DESIGN: Population-based cross-sectional study. METHODS: Data were collected from six communities affected by MVIs involving firearms that occurred between 2015 and 2020. Participants were randomly selected through address-based sampling, and depression was assessed using Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) diagnostic-level major depressive episode (MDE). RESULTS: Overall, the MDE prevalence was 17·2% since the MVI, 15·4% in the past year, and 8·2% in the past month. Significant risk factors for MDE since MVIs include high exposure to the incident (adjusted relative risk [aRR] = 1·32, 95% confidence interval [CI]: 19-1·60), being aged 18-29 years (aRR = 2·52, 95% CI: 1·61-3·95), being a woman (aRR = 1·58, 95% CI: 1·27-1·96), having low social support (aRR = 1·80, 95% CI: 1·46-2·22), and experiencing past sexual or physical trauma (aRR = 2·20, 1·52-3·19). CONCLUSION: Our study reveals a high burden of depression within communities affected by MVIs involving firearm use. Persons with high exposure to the MVIs and certain demographic groups had greater risks for MDE. These findings highlight the long-term mental health burden in communities affected by MVIs and underscore the necessity of providing mental health services in its aftermath.

Predictors of medical examinations following child and adolescent rapes in a national sample of women.

Childhood rape occurs frequently in our society and is associated with adverse consequences. Despite the severity of these outcomes, there appear to be many obstacles for children to receive postrape medical care. To date, it is unclear what proportion of childhood rape victims receive postrape medical examination or what factors predict receipt of this medical care. This study instigated the factors predicting immediate medica care for women who were raped during childhood. Data for the study were obtained from the final wave of the 2-year, longitudinal National Women's Study. Results indicated that the majority of women did not receive medical care following their childhood rape. Although women raped as adolescents were more likely to receive a postrape exam, logistic regression analyses indicated that rape characteristics (e.g., reporting the assault, concerns about sexually transmitted diseases [STDs]) mediated the relationship between age of victimization and receipt of medical care. Implications of these findings are discussed.

Predictors of post-rape medical care in a national sample of women.

BACKGROUND: Rape has a negative impact on physical and mental health, health-related behaviors, and health service utilization. Timely medical care is important for preventive services. METHODS: Cross-sectional data were obtained from a larger 2-year longitudinal study, the National Women's Study (NWS). A total of 3006 adult women participated in the final data collection wave of the NWS. During a structured telephone interview, women who reported a most-recent or only rape incident during adulthood were asked about rape characteristics, reporting to authorities, medical care, and rape-related concerns. The main outcome measures were receipt and timing of medical care received after an adult rape, and factors influencing whether or not medical care was received. RESULTS: Of the sample, 214 (7.1%) had experienced a most-recent or only rape as an adult (aged >/=18), and 56 (26.2%) received rape-related medical care following that incident. The final model multivariable logistic regression indicated that reporting the crime to police or other authorities (odds ratio [OR], 9.45; 95% confidence interval [CI]=3. 34-26.70) and fear of sexually transmitted diseases (OR, 8.61; 95% CI=3.12-23.72) were significant predictors of receipt of post-rape medical care. CONCLUSIONS: One in five victims reported an adult rape to police or other authorities; these women were nine times more likely to receive medical care than those who did not. Public health efforts are needed to increase the proportion of rape victims who receive immediate post-rape medical care.

Which comes first in the pathogenesis of bulimia nervosa: dieting or bingeing?

OBJECTIVE: Clinical experience has indicated that dieting usually precedes the onset of binge eating in the development of bulimia nervosa (BN). However, data confirming this in nonclinical, representative samples are lacking. METHOD: Using results obtained from the National Women's Study (NWS), we were able to determine the chronological relationship between age of onset of significant dieting (attempting to lose 15 lbs) and onset of bingeing in 85 respondents who met DSM-III-R criteria for BN. These respondents were a subset of over 3,000 female adult U.S. women who completed a random telephone interview (averaging 40 min and including screenings for rape, sexual molestation, aggravated assault, posttraumatic stress disorder [PTSD], and BN). RESULTS: We found that the age of first serious attempt to diet preceded the age of first binge in 46% of cases. There were no significant differences in histories of victimization experiences among the groups. First binge preceded first serious diet in 37% of cases, and these behaviors occurred during the same age in 17% of cases. DISCUSSION: These data confirm that dieting is more likely to precede binge eating, although binge eating precedes significant dieting in a substantial proportion of bulimic respondents.

Assault, PTSD, family substance use, and depression as risk factors for cigarette use in youth: findings from the National Survey of Adolescents.

A national household probability sample of 4,023 adolescents aged 12 to 17 years was surveyed by telephone via structured clinical interview to determine the impact of familial substance use, sexual and physical assault, witnessed violence, depression and posttraumatic stress disorder (PTSD) on risk of smoking. Results indicated that familial substance use increased risk of smoking only for boys and sexual assault or depression increased risk of smoking only for girls. Age, Caucasian ethnicity, and experiencing physical assault or witnessing violence elevated risk of current cigarette use for both genders. By contrast, PTSD per se was not associated with increased risk of smoking, after the effects of other variables were controlled.

Delay in disclosure of childhood rape: results from a national survey.

OBJECTIVE: This study sought to gather representative data regarding the length of time women who were raped before age 18 delayed prior to disclosing such rapes, whom they disclosed to, and variables that predicted disclosure within 1 month. METHOD: Data were gathered from 3,220 Wave II respondents from the National Women's Study (Resnick, Kilpatrick, Dansky, Saunders, & Best, 1993), a nationally representative telephone survey of women's experiences with trauma and mental health. Of these, 288 retrospectively reported at least one rape prior to their 18th birthday. Details of rape experiences were analyzed to identify predictors of disclosure within 1 month. RESULTS: Fully 28% of child rape victims reported that they had never told anyone about their child rape prior to the research interview; 47% did not disclose for over 5 years post-rape. Close friends were the most common confidants. Younger age at the time of rape, family relationship with the perpetrator, and experiencing a series of rapes were associated with disclosure latencies longer than 1 month; shorter delays were associated with stranger rapes. Logistic regression revealed that age at rape and knowing the perpetrator were independently predictive of delayed disclosure. CONCLUSIONS: Delayed disclosure of childhood rape was very common, and long delays were typical. Few variables were identified that successfully predicted disclosure behavior, but older age and rape by a stranger were associated with more rapid disclosure. This suggests that the likelihood of disclosure in a given case is difficult to estimate, and predictions based on single variables are unwarranted.

Risk factors for adolescent substance abuse and dependence: data from a national sample.

A national household probability sample of 4,023 adolescents aged 12 to 17 years was interviewed by telephone about substance use, victimization experiences, familial substance use, and posttraumatic reactions to identify risk factors for Diagnostic and Statistical Manual of Mental Disorders--(4th ed.; American Psychiatric Association, 1994) defined substance abuse/dependence. Age and ethnicity data were available for 3,907 participants. Major findings were (a) adolescents who had been physically assaulted, who had been sexually assaulted, who had witnessed violence, or who had family members with alcohol or drug use problems had increased risk for current substance abuse/dependence; (b) posttraumatic stress disorder independently increased risk of marijuana and hard drug abuse/dependence; and (c) when effects of other variables were controlled, African Americans, but not Hispanics or Native Americans, were at approximately 1/3 the risk of substance abuse/dependence as Caucasians.

Comorbidity of bulimia nervosa and alcohol use disorders: results from the National Women's Study.

OBJECTIVE: The nature of the relationship between bulimia nervosa (BN) and alcohol abuse/alcohol dependence (AA/AD) and the extent to which women with BN+AA differ from women with BN-AA were examined in a national sample of women (N = 3,006). METHOD: The sample of was generated by multistage geographic sampling and interviews were conducted by telephone. RESULTS: AA was higher in women with BN compared to women without BN or binge eating disorder, only when the influence of major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) was controlled. Prevalence rates of AA and AD were similar in women with BN, MDD, and PTSD. Analyses indicated that the relationship between BN and AA/AD may be indirect and influenced by associations with MDD and PTSD. Women with BN+AA did not differ from those with BN-AA on most variables concerning victimization, family of origin, and disordered eating. DISCUSSION: Evaluation of MDD and PTSD in women presenting for treatment of BN and/or alcohol use disorders (AUDs) is recommended.

Prevention of post-rape psychopathology: preliminary findings of a controlled acute rape treatment study.

Violent sexual assault such as rape typically results in extremely high levels of acute distress. The intensity of these acute psychological reactions may play a role in later recovery, with higher levels of immediate distress associated with poorer outcome. Unfortunately, post-rape forensic evidence collection procedures may serve to increase, rather than reduce initial distress, potentially exacerbating future psychopathology. To address these concerns, an acute time-frame hospital-based video intervention was developed to: (a) minimize anxiety during forensic rape exams, and (b) prevent post-rape posttraumatic stress disorder (PTSD), panic, and anxiety. Preliminary data indicated that (1) psychological distress at the time of the exam was strongly related to PTSD symptomatology 6 weeks post-rape, and (2) the video intervention successfully reduced distress during forensic exams.

Factors related to the reporting of childhood rape.

OBJECTIVE: The aim of this study was to examine whether there would be differences in reported versus unreported cases of childhood rape on incident characteristics including life threat, physical injury, identity of the perpetrator, frequency of assault(s), and rates of posttraumatic stress disorder or major depression. METHOD: In a telephone interview, a national probability sample of 4,008 (weighted) adult women was screened for a history of completed rape in childhood. Respondents were also assessed for DSM-III-R diagnoses of major depressive episode and/or posttraumatic stress disorder (PTSD). Three hundred forty-one (8.5%) of these women were victims of at least one rape prior to the age of 18, for a total of 437 completed rapes. Of these 437 rape incidents, 52 (11.9%) were reported to the police or other authorities. RESULTS: Significant differences were obtained between reported versus nonreported cases on incident characteristics, including life threat, physical injury, identity of the perpetrator. Reported cases were more likely to involve life threat and/or physical injury, and were more likely to have been committed by a stranger than nonreported cases. No significant differences between reported and nonreported cases were found concerning whether the rape involved a single incident versus series of events, or rates of PTSD or major depression. CONCLUSIONS: Findings suggest that different characteristics are associated with reported versus unreported cases of childhood rape. Since few cases of childhood rape are actually reported to the authorities, it appears that we may be missing valuable information. Implications for research and clinical intervention are discussed.

The socioeconomic impact of interpersonal violence on women.

Prospective data from a nationally representative sample of women were used to examine 4 objective indexes of social adjustment following direct, interpersonal crime. Household income, marital status, employment, and education level were evaluated as risk factors for and outcomes of victimization. Data were collected in 3 waves at 1-year intervals, and 2,863 women completed all 3 waves. Results indicate that women experience increased risk for victimization when income is below poverty level and when newly divorced. Further, victimization appears to increase women's risk for unemployment, reduced income, and divorce. The cyclical nature of victimization is discussed.

Risk factors for rape, physical assault, and posttraumatic stress disorder in women: examination of differential multivariate relationships.

The National Women's Study, a 2-year, three-wave longitudinal investigation, employed a national probability sample of 3,006 adult women to: (a) identify separate risk factors for rape and physical assault, and (b) identify separate risk factors associated with post-rape posttraumatic stress disorder (PTSD) and post-physical assault PTSD. This investigation differed from previous studies in that it prospectively examined risk factors at the multivariate, as opposed to univariate level. Overall, past victimization, young age, and a diagnosis of active PTSD increased women's risk of being raped. By contrast, past victimization, minority ethnic status, active depression, and drug use were associated with increased risk of being physically assaulted. Risk factors for PTSD following rape included a history of depression, alcohol abuse, or experienced injury during the rape. However, risk factors for PTSD following physical assault included only a history of depression and lower education.

Criminal victimization, posttraumatic stress disorder, and comorbid psychopathology among a community sample of women.

This paper provides information on the relation between victimization status, crime factors, posttraumatic stress disorder (PTSD), and several other psychological disorders among a community sample of women. Results indicated that victims of crime were more likely than nonvictims to suffer from PTSD, major depressive episode, agoraphobia, obsessive-compulsive disorder, social phobia, and simple phobia. Furthermore, life threat was associated with increased risk of major depression, agoraphobia, obsessive-compulsive disorder, and social phobia. Completed rape was strongly related to almost every disorder assessed, while robbery and burglary were not related to any disorder. When demographics, victimization status, and crime factors were entered hierarchically into multivariate logistic regressions with PTSD in the final step, associations between victimization status, other crime characteristics (e.g., life threat, injury), and non-PTSD Axis I disorders were greatly reduced. This suggests that PTSD may be an important mediating factor in the victimization-psychopathology relation for many disorders.

PTSD as a mediator between childhood rape and alcohol use in adult women.

OBJECTIVE: Though a relationship between childhood sexual abuse and later alcohol use among women has been documented, little is known about the pathways that link these two variables. A tension reduction hypothesis posits that emotional distress precedes substance usage. PTSD symptomatology resulting from childhood sexual abuse is examined as a possible source of emotional distress that may cause subsequent alcohol use. METHOD: A sample of adult women was selected and interviewed on two occasions 1 year apart and childhood rape history, lifetime PTSD symptoms, and lifetime alcohol use were assessed. Path analytic techniques were used to evaluate the mediating role of PTSD symptoms on the relationship between childhood rape and subsequent alcohol use. RESULTS: A history of childhood rape doubled the number of alcohol abuse symptoms that women experienced in adulthood. Path analysis and cross-validation results demonstrated significant pathways connecting childhood rape to PTSD symptoms and PTSD symptoms to alcohol use. CONCLUSIONS: The results of the present study suggest that PTSD symptomatology which develops after childhood rape may be one of many variables that affect alcohol abuse patterns in women who were victims of childhood sexual abuse.

Predicting PTSD in women with a history of childhood rape.

The impact of factors that predispose childhood rape victims to develop posttraumatic stress disorder (PTSD) is important in understanding both the impact of childhood rape and the development of PTSD as a psychological disorder. The present study attempted to determine which crime, perpetrator, victim, and aftermath characteristics are related to PTSD status. A national representative sample of women (N = 3,220) were interviewed about their history of rape, trauma-related variables, and PTSD status. Consistent with research on crime victims, life threat and physical injury discriminated PTSD status in a sample of childhood rape victims. In addition, two other domains were related to PTSD development: (1) testification about rape and (2) rape types. The present findings are discussed in relation to previous research.

A 2-year longitudinal analysis of the relationships between violent assault and substance use in women.

Women experience alarming levels of physical and sexual assault, which may lead to escalation of substance use. Reciprocally, evidence from cross-sectional studies indicates that substance use may increase risk of assault. To date, directionality of this relationship remains unclear. This issue is addressed by the present 3-wave longitudinal study in which a national probability sample of 3,006 women were followed for 2 years. Dependent measures were obtained at each wave of the study and included questions about lifetime and new assault status, alcohol abuse, and drug use. Wave 1 use of drugs, but not abuse of alcohol, increased odds of new assault in the subsequent 2 years. Reciprocally, after a new assault, odds of both alcohol abuse and drug use were significantly increased, even among women with no previous use or assault history. For illicit drug use, findings support a vicious cycle relationship in which substance use increases risk of future assault and assault increases risk of subsequent substance use.

Health impact of interpersonal violence. 1: Prevalence rates, case identification, and risk factors for sexual assault, physical assault, and domestic violence in men and women.

This integrated series of three articles deals with the relationship between interpersonal violence and health. In the first article, the scope of the problem, the prevalence of interpersonal violence, and information on rates of violent crime in specific subgroups of people are outlined. The role of the treating physician and other health professionals in failing to identify cases of assault-related illness is considered, as are the factors that place individuals at increased risk of assault. In the second article, the impact of interpersonal violence on physical and mental health is reviewed, and the results of basic and applied clinical research into acute and chronic emotional and physical sequalae are discussed. The third article includes an outline of implications for research, training, and clinical practice using behavioral techniques in treating victims of interpersonal violence.
