There was a substantial burden of acute PTSD and depression in Manhattan after the September 11 attacks. Experiences involving exposure to the attacks were predictors of current PTSD, and losses as a result of the events were predictors of current depression. In the aftermath of terrorist attacks, there may be substantial psychological morbidity in the population.
With a national household probability sample of 4,023 telephone-interviewed adolescents ages 12-17, this study provides prevalence, comorbidity, and risk-factor data for posttraumatic stress disorder (PTSD), major depressive episode (MDE), and substance abuse/dependence (SA/D). Roughly 16% of boys and 19% of girls met criteria for at least 1 diagnosis. Six-month PTSD prevalence was 3.7% for boys and 6.3% for girls, 6-month MDE prevalence was 7.4% for boys and 13.9% for girls, and 12-month SA/D prevalence was 8.2% for boys and 6.2% for girls. PTSD was more likely to be comorbid than were MDE and SA/D. Results generally support the hypothesis that exposure to interpersonal violence (i.e., physical assault, sexual assault, or witnessed violence) increases the risk of these disorders and of diagnostic comorbidity.
Prevalence of crime and noncrime civilian traumatic events, lifetime posttraumatic stress disorder (PTSD), and PTSD in the past 6 months were assessed in a sample of U.S. adult women (N = 4,008). Random digit-dial telephone methods were used to identify study participants. Structured telephone interviews for assessment of specific crime or other traumatic event history and PTSD were conducted by trained female interviewers. Lifetime exposure to any type of traumatic event was 69%, whereas exposure to crimes that included sexual or aggravated assault or homicide of a close relative or friend occurred among 36%. Overall sample prevalence of PTSD was 12.3% lifetime and 4.6% within the past 6 months. The rate of PTSD was significantly higher among crime versus noncrime victims (25.8% vs. 9.4%). History of incidents that included direct threat to life or receipt of injury was a risk factor for PTSD. Findings are compared with data from other epidemiological studies. Results are discussed as they relate to PTSD etiology.
Prevalence of posttraumatic stress disorder (PTSD) defined according to the American Psychiatric Association’s Diagnostic and Statistical Manual fifth edition (DSM-5; 2013) and fourth edition (DSM-IV; 1994) was compared in a national sample of U.S. adults (N = 2,953) recruited from an online panel. Exposure to traumatic events, PTSD symptoms, and functional impairment were assessed online using a highly structured, self-administered survey. Traumatic event exposure using DSM-5 criteria was high (89.7%), and exposure to multiple traumatic event types was the norm. PTSD caseness was determined using Same Event (i.e., all symptom criteria met to the same event type) and Composite Event (i.e., symptom criteria met to a combination of event types) definitions. Lifetime, past-12-month, and past 6-month PTSD prevalence using the Same Event definition for DSM-5 was 8.3%, 4.7%, and 3.8% respectively. All 6 DSM-5 prevalence estimates were slightly lower than their DSM-IV counterparts, although only 2 of these differences were statistically significant. DSM-5 PTSD prevalence was higher among women than among men, and prevalence increased with greater traumatic event exposure. Major reasons individuals met DSM-IV criteria, but not DSM-5 criteria were the exclusion of nonaccidental, nonviolent deaths from Criterion A, and the new requirement of at least 1 active avoidance symptom.
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.
Objectives. We estimated prevalence and assessed correlates of emotional, physical, sexual, and financial mistreatment and potential neglect (defined as an identified need for assistance that no one was actively addressing) of adults aged 60 years or older in a randomly selected national sample. Methods. We compiled a representative sample by random digit dialing across geographic strata. We used computer-assisted telephone interviewing to standardize collection of demographic, risk factor, and mistreatment data. We subjected prevalence estimates and mistreatment correlates to logistic regression. Results. We analyzed data from 5777 respondents. One-year prevalence was 4.6% for emotional abuse, 1.6% for physical abuse, 0.6% for sexual abuse, 5.1% for potential neglect, and 5.2% for current financial abuse by a family member. One in 10 respondents reported emotional, physical, or sexual mistreatment or potential neglect in the past year. The most consistent correlates of mistreatment across abuse types were low social support and previous traumatic event exposure. Conclusions. Our data showed that abuse of the elderly is prevalent. Addressing low social support with preventive interventions could have significant public health implications.
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.
whether a crime was committed or whether harm was intended. Injury was reported for 52% of forcible rape incidents and 30% of drug-facilitated or incapacitated rape incidents assessed. Medical care was received following 19% of forcible rape incidents and 21% of drug-facilitated or incapacitated rape incidents. Perpetrators were known to the victim in a high percentage of forcible rape, drug-facilitated, and incapacitated rape incidents. Rape among Women in U.S. Colleges Estimates are that 673,000 of nearly 6 million women (11.5%) currently attending American colleges have ever been raped. 2 This includes an estimated half-million college women who have been forcibly raped, 160,000 who have experienced drug-facilitated rape, and over 200,000 who have experienced incapacitated rape. 1 During the past year alone, 300,000 college women (5.2%) were raped: nearly 200,000 who have been forcibly raped, nearly 100,000 who have experienced drug-facilitated rape, and over 100,000 who have experienced incapacitated rape. Among college women, about 12% of rapes were reported to law enforcement. Consistent with the national sample, victims of drug-facilitated or incapacitated rape were less likely than victims of forcible rape to report to the authorities. Barriers to reporting rape incidents to law enforcement among college women included: not wanting others to know about the rape, fear of retaliation, perception of insufficient evidence, uncertainty about whether a crime was committed or harm intended, and uncertainty about whether the incident was "serious enough". Injury was reported for 47% of forcible rape incidents and 20% of drug-facilitated or incapacitated incidents. Medical care was received following 14% of forcible rape incidents and 19% of drugfacilitated or incapacitated incidents. Perpetrators were known to victims in most rape cases.
