Prevalence and Risk Factors of Depression and Posttraumatic Stress Disorder After a Mass Shooting.

This cross-sectional study examines the self-reported mental health outcomes of adults 4 years after witnessing and surviving the shooting at the Route 91 Harvest Music Festival in Las Vegas, Nevada.

Who tests for lead and why? A 10-year analysis of blood lead screening, follow-up and CNS outcomes in a statewide US healthcare system.

OBJECTIVES: This study aims to determine (1) which providers in US healthcare systems order lead tests, why and at what frequency and (2) whether current patient population lead levels are predictive of clinical outcomes. METHODS: Retrospective medical record study of all blood lead tests in the Medical University of South Carolina healthcare system 2012-2016 and consequent evidence of central nervous system (CNS)-related disease across a potential 10-year window (2012-2022). RESULTS: Across 4 years, 9726 lead tests resulted for 7181 patients (49.0% female; 0-94 years), representing 0.2% of the hospital population. Most tests were for young (76.6%≤age 3) and non-Hispanic black (47.2%) and Hispanic (26.7%) patients. A wide variety of providers ordered tests; however, most were ordered by paediatrics, psychiatry, internal medicine and neurology. Lead levels ranged from ≤2.0 µg/dL (80.8%) to ≥10 µg/dL (0.8%; max 36 µg/dL). 201 children (3.1%) had initial lead levels over the reference value for case management at the time (5.0 µg/dL). Many high level children did not receive follow-up testing in the system (36.3%) and those that did often failed to see levels fall below 5.0 µg/dL (80.1%). Non-Hispanic black and Hispanic patients were more likely to see lead levels stay high or go up over time. Over follow-up, children with high lead levels were more likely to receive new attention-deficit/hyperactivity disorder and conduct disorder diagnoses and new psychiatric medications. No significant associations were found between lead test results and new CNS diagnoses or medications among adults. CONCLUSIONS: Hospital lead testing covers a small portion of patients but includes a wide range of ages, presentations and provider specialities. Lack of lead decline among many paediatric patients suggests there is room to improve provider guidance around when to test and follow-up.

Association of Public Works Disasters with Substance Use Difficulties: Evidence from Flint, Michigan, Five Years after the Water Crisis Onset.

Public works environmental disasters such as the Flint water crisis typically occur in disenfranchised communities with municipal disinvestment and co-occurring risks for poor mental health (poverty, social disconnection). We evaluated the long-term interplay of the crisis and these factors with substance use difficulties five years after the crisis onset. A household probability sample of 1970 adults living in Flint during the crisis was surveyed about their crisis experiences, use of substances since the crisis, and risk/resilience factors, including prior potentially traumatic event exposure and current social support. Analyses were weighted to produce population-representative estimates. Of the survey respondents, 17.0% reported that substance use since the crisis contributed to problems with their home, work, or social lives, including 11.2% who used despite a doctor's warnings that it would harm their health, 12.3% who used while working or going to school, and 10.7% who experienced blackouts after heavy use. A total of 61.6% of respondents reported using alcohol since the crisis, 32.4% using cannabis, and 5.2% using heroin, methamphetamine, or non-prescribed prescription opioids. Respondents who believed that exposure to contaminated water harmed their physical health were more likely to use substances to the detriment of their daily lives (RR = 1.32, 95%CI: 1.03-1.70), as were respondents with prior potentially traumatic exposure (RR = 2.99, 95%CI: 1.90-4.71), low social support (RR = 1.94, 95%CI: 1.41-2.66), and PTSD and depression (RR's of 1.78 and 1.49, respectively, p-values < 0.01). Public works disasters occurring in disenfranchised communities may have complex, long-term associations with substance use difficulties.

A preliminary examination of sexual and physical victimization 6 months after recent rape.

One in four US women will experience a completed or attempted rape in their lifetime, and more than 50% of survivors will experience two or more rapes. Rape and physical violence also co-occur. Multiple experiences of sexual and physical violence are associated with elevated mental and physical health problems. This secondary analysis examined the prevalence and correlates of experiencing sexual or physical violence within 6 months of a sexual assault medical forensic exam (SAMFE). Between May 2009 and December 2013, 233 female rape survivors aged 15 and older were enrolled in a randomized controlled trial during a SAMFE in the emergency department (ED). Demographics, rape characteristics, distress at the ED, and pre-rape history of sexual or physical victimization were assessed. New sexual and physical victimization was assessed 6 months after the SAMFE via telephone interview. Six months after the exam, 21.7% reported a new sexual or physical victimization. Predictors of revictimization during follow-up included sexual or physical victimization prior to the index rape, making less than $10,000 annually, remembering the rape well, life threat during the rape, and higher distress at the ED. In adjusted models, only pre-rape victimization and making less than $10,000 annually were associated with revictimization. Factors assessed at the ED can inform subsequent victimization risk. More research is needed to prevent revictimization among recent rape victims. Policies to provide financial support to recent rape victims and/or targeted prevention for those with pre-rape victimization at the SAMFE could reduce revictimization risk. TRIAL REGISTRATION: NCT01430624.

Using the 5C model to understand COVID-19 vaccine hesitancy across a National and South Carolina sample.

Vaccine hesitancy is a serious threat to global health; however, significant COVID-19 vaccine hesitancy exists throughout the United States. The 5C model, which postulates five person-level determinants for vaccine hesitancy - confidence, complacency, constraints, risk calculation, and collective responsibility - provides one theoretical way of understanding COVID-19 vaccine hesitancy. The present study examined the effects of these 5C drivers of vaccine behavior on early vaccine adoption and vaccine intentions above and beyond theoretically salient demographic characteristics and compared these associations across a National sample (n = 1634) and a statewide sample from South Carolina (n = 784) - a state with documented low levels of COVID-19 vaccination uptake. This study used quantitative and qualitative data collected in October 2020 to January 2021 from the MFour-Mobile Research Panel, a large, representative non-probability sample of adult smartphone users. Overall, the South Carolina sample reported lower COVID-19 vaccine intentions and higher levels of 5C barriers to vaccine uptake compared to the National sample. Findings further indicated that both demographic characteristics (race) and certain drivers of vaccine behavior (confidence and collective responsibility) are associated with vaccine trust and intentions across samples above and beyond other variables. Qualitative data indicated that COVID-19 vaccine hesitancy was driven by fears about the quick vaccine development, limited research, and potential side effects. Although there are some limitations to the cross-sectional survey data, the present study offers valuable insight into factors associated with early COVID-19 vaccine hesitancy across the United States.

Prevalence of Depression and Posttraumatic Stress Disorder in Flint, Michigan, 5 Years After the Onset of the Water Crisis.

Importance: Environmental disasters, such as the Flint, Michigan, water crisis, are potentially traumatic events (PTEs) that may precipitate long-term psychiatric disorders. The water crisis was associated with acute elevations in mental health problems in the Flint community, but long-term psychiatric sequelae have not yet been evaluated using standardized diagnostic measures. Objective: To investigate the prevalence of and factors associated with current presumptive diagnostic-level major depression and posttraumatic stress disorder (PTSD) among Flint residents 5 years after the onset of the crisis. Design, Setting, and Participants: In this cross-sectional study, a household probability sample of 1970 adults living in Flint, Michigan, during the crisis were surveyed about their crisis experiences, their psychological symptoms 5 years later, and their access to and use of mental health services in the intervening years. Analyses were weighted to produce population-representative estimates. Main Outcomes and Measures: Presumptive Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5) diagnostic-level past-year major depression and PTSD. Results: Among 1970 respondents, 1061 of 1946 reporting sex (54.5%) were women; 1043 of 1951 reporting race (53.5%) were Black or African American and 829 (42.5%) were White; and 1895 of 1946 reporting ethnicity (97.4%) were non-Hispanic. Overall, 435 (22.1%) met DSM-5 criteria for presumptive past-year depression, 480 (24.4%) for presumptive past-year PTSD, and 276 (14.0%) for both disorders. Residents who believed that their or their family's health was harmed by contaminated water (eg, risk ratio [RR] for depression: 2.23; 95% CI, 1.80-2.76), who had low confidence in public-official information (eg, RR for PTSD, 1.44; 95% CI, 1.16-1.78), who had previous exposure to PTEs (eg, RR for both disorders: 5.06; 95% CI, 2.99-8.58), or who reported low social support (eg, RR for PTSD, 2.58; 95% CI, 1.94-3.43) had significantly higher risk for depression, PTSD, and comorbidity. PTEs involving prior physical or sexual assault were especially potent risk factors (eg, both disorders: RR, 7.30; 95% CI, 4.30-12.42). Only 685 respondents (34.8%) were ever offered mental health services to assist with water-crisis-related psychiatric symptoms; most (543 [79.3%]) who were offered services utilized them. Conclusions and Relevance: In this cross-sectional study of psychiatric disorder in Flint, Michigan, presumptive depression and PTSD were highly prevalent 5 years after the onset of the water crisis. These findings suggest that public-works environmental disasters have large-scale, long-term psychological sequelae. The Flint community may require expanded mental health services to meet continued psychiatric need. National disaster preparedness and response programs should consider psychiatric outcomes.

Mitigating the mental health consequences of mass shootings: An in-silico experiment.

Background: There is emerging evidence that mass shootings are associated with adverse mental health outcomes at the community level. Data from other mass-traumatic events examined the effectiveness of usual care (UC), (i.e., psychological first aid approaches without triage), and stepped care (SC) approaches, with triage, in reducing the burden of post-traumatic stress disorder (PTSD) in a community. Methods: We built an agent-based model of 118,000 people that was demographically comparable to the population of Parkland and Coral Springs, Florida, US. We parametrized the model with data from other traumatic events. Using simulations, we then estimated the community prevalence of PTSD one month following the Stoneman Douglas High School (Florida, US) shooting and reported the potential reach, effectiveness, and cost effectiveness of different what-if treatment scenarios (SC or UC) over a two-year period. Findings: One month following the mass shooting, PTSD prevalence in the community was 11.3% (95% CI: 11.1-11.5%). The reach of SC was 3461 (95% CI: 3573-3736) per 10,000 and the reach of UC was 2457 (95% CI: 2401-2510) per 10,000. SC was superior to UC in reducing PTSD prevalence, yielding, after two years, a risk difference of -0.044 (95% CI, -0.046 to -0.042) and a risk ratio of 0.452 (95% CI, 0.437-0.468). SC was also superior to UC in reducing the persistence of PTSD, yielding, after two years, a risk difference of -0.39 (95% CI, -0.401 to -0.379) and a risk ratio of 0.452 (95% CI, 0.439-0.465). The incremental cost-effectiveness of SC compared to UC was $2718.49 per DALYs saved, and $0.47 per PTSD-free day. Interpretation: This simulation demonstrated the potential benefits of different community-level approaches in mitigating the burden of PTSD following a mass shooting. These results warrant further research on community-based interventions to mitigate the mental health consequences of mass shootings. Funding: None.

The Role of Discrimination Experiences in Postrape Adjustment Among Racial and Ethnic Minority Women.

Although recent studies have linked discrimination frequency among Black and Latinx individuals to PTSD symptom severity, to our knowledge, these associations have yet to be examined among a diverse sample of recent rape survivors. The current secondary analysis of existing data examined the role of discrimination experiences in post-traumatic stress disorder (PTSD) symptoms, depression, and alcohol and drug problems among a racially and ethnically diverse sample of recent rape survivors. Participants were 139 Black (48.2%; n = 67), American Indian (18.7%; n = 26), Hispanic (15.1%; n = 21), and mixed race (17.3%; n = 24) girls and women age 15 or older who presented to the emergency department (ED) for a sexual assault forensic medical exam. They were randomly assigned to one of three intervention conditions, and completed a six-month postrape follow-up, including questions about mental health, substance use problems, and discrimination experiences. Regression analyses revealed that Black women experienced discrimination in significantly more situations and with greater frequency compared to American Indian and Hispanic women. Discrimination frequency was positively associated with PTSD and depression symptoms even after controlling for age, education, race, and intervention condition, but was not associated with alcohol or drug problems. Findings highlight the importance of attending to the heterogeneous experiences of discrimination among racial and ethnic minority women. Future work should adapt evidence-based early interventions to be maximally effective at combating both racial and sexual trauma exposures.

A secondary analysis of a brief video intervention on suicidal ideation among recent rape victims.

Although rape has been linked to risk for suicidal ideation and attempts, there are scant data on the efficacy of brief interventions to reduce suicidality among recent rape victims. This secondary analysis of a randomized controlled trial investigated whether a video intervention delivered in the emergency department (ED), cortisol measured at the ED, and prior rape history predicted postrape suicidal ideation independently or in combination with the other predictors. Participants were 235 women aged 15-71 years who presented to the ED for a sexual assault medical forensic examination and were randomly assigned to either receive a video intervention that addressed avoidance and promoted healthy coping strategies or standard care prior to the examination. Participants also provided a blood sample for cortisol and completed at least one of three follow-ups at 6 weeks, 3 months, or 6 months postrape. The intervention conferred protection against suicidal ideation among women with elevated cortisol and a prior rape; however, it did not reduce risk for women without a prior rape, particularly those with elevated cortisol. It may be important to consider the influence of prior rape and neuroendocrine reactivity in developing treatments to address suicidal ideation among rape victims. More specifically, there appears to be value in screening victims for prior rape and administering this brief intervention to reduce suicidal ideation; however, other avenues should be explored for victims without a prior rape history.

Post-Sexual Assault Mental Health: A Randomized Clinical Trial of a Video-Based Intervention.

The current study assessed the efficacy of a brief video intervention (Prevention of Post-Rape Stress [PPRS]) delivered in the emergency department to recent sexual assault (SA) victims. PPRS was compared to treatment as usual (TAU) and an active control condition (Pleasant Imagery and Relaxation Instruction [PIRI]). Primary outcomes were posttraumatic stress disorder (PTSD) symptoms and perceived present control. Prior SA was examined as a moderator of treatment effects. Women (n = 233; aged 15 years and older; 59.70% identified as a racial or ethnic minority) who received a post-SA medical forensic exam participated in the study (NCT01430624). Participants were randomized to watch the PPRS video (n = 77), the PIRI video (n = 77), or receive TAU (n = 79). Participants completed measures of PTSD symptoms and perceived present control 1.5-, 3-, and 6-months post-SA. An interaction between condition and prior SA was found on PTSD symptom frequency and on perceived present control. Among women with a prior SA, women in the PPRS versus TAU condition reported less frequent PTSD symptoms 6-months post-SA. Those in the PPRS condition had lower perceived present control than those in the TAU condition among those with no prior SA 3-months post-SA. However, at 6-months post-SA, among women with a prior SA, women in the PPRS reported higher perceived present control than those in TAU. These findings partially replicate a prior study in which PPRS was found to be beneficial in mitigating the development of PTSD symptoms, but only for women with a prior SA.

Longitudinal Relations among Adolescent Risk Behavior, Family Cohesion, Violence Exposure, and Mental Health in a National Sample.

Violence is a public health concern linked with mental health problems among adolescents, and risk behavior increases the likelihood of violence exposure. Family cohesion may attenuate the negative effects of risk behavior. The purpose of this study was to examine family cohesion as a moderator in the relation between risk behavior (substance use and delinquency) and violence exposure, and to explore longitudinal associations among cohesion, violence exposure, and subsequent mental health outcomes (PTSD and depression). Data were drawn from the National Survey of Adolescents-Replication, a nationally representative sample of 3604 adolescents, with data collected via structured phone interviews at three waves spanning a two-year period. Hypotheses were tested using longitudinal structural equation modeling. Findings revealed that high family cohesion attenuated the relation between risk behavior and subsequent violence exposure. Wave 2 violence exposure was associated with more Wave 3 mental health problems, but high family cohesion was related to fewer subsequent symptoms. Follow-up analyses revealed that family cohesion moderated the relation between risk behavior and experiencing, but not witnessing, violence. Several demographic associations were observed. Although risk behavior increases exposure to violence, and in turn, mental health problems, family cohesion may serve as a protective factor, attenuating the link between risk behavior and subsequent negative consequences. This effect emerged even when accounting for demographic and socioeconomic covariates. Interventions with adolescents should target family relationships as a protective factor to reduce risk of violence exposure and mental health problems, particularly for adolescents who are engaging in high-risk behaviors.

Network Analysis of Posttraumatic Stress Disorder Symptoms in a National Sample of U.S. Adults: Implications for the Phenotype and the ICD-11 Model of PTSD.

The phenotype for posttraumatic stress disorder (PTSD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Diseases (DSM-5) includes 20 symptoms in four clusters. In contrast, the PTSD model in the 11th revision of the International Classification of Diseases (ICD-11) includes six symptoms in three clusters. Whether those six symptoms are, in fact, the most central symptoms of the PTSD phenotype remains an open question. In a previous network analysis of DSM-5 PTSD symptoms, Mitchell and colleagues (2017) reported limited overlap between central PTSD symptoms and those in the ICD-11 model in a national sample of U.S. veterans. The present study sought to replicate and extend upon these findings in a large national sample of U.S. adults (N = 2,953). Centrality statistics from both a replication sample (i.e., participants with DSM-5 PTSD, n = 173) and an extension sample (i.e., participants who had been exposed to potentially traumatic events, n = 2,468) were moderately strongly convergent with the findings reported by Mitchell et al., rs = .54-.73. Additionally, only three of the six most central symptoms in both the replication and extension samples overlapped with the ICD-11 model, indicating that the ICD-11 model (a) failed to include network-central symptoms of the PTSD phenotype and (b) included extra symptoms that were not network-central. Several symptoms from the DSM-5 Criterion D cluster (negative alterations in cognition and mood) that were excluded in ICD-11 were found to be among the most central PTSD symptoms.

Prior Interpersonal Violence Exposure and Experiences During and After a Disaster as Predictors of Posttraumatic Stress Disorder and Depression Among Adolescent Victims of the Spring 2011 Tornadoes.

The purpose of the current report was to examine prior history of exposure to interpersonal violence (IPV), as compared with prior accident or prior disaster exposure, experiences during and after a disaster, and demographic variables as predictors of past month posttraumatic stress disorder (PTSD) and depression severity among adolescents exposed to the tornadoes in Alabama and Missouri. IPV exposure has been consistently identified as a unique category of potentially traumatic events (PTE) that significantly increases risk for development of PTSD and other difficulties relative to other event types among adolescents. A population-based sample of adolescents and caregivers (N = 2,000) were recruited randomly from tornado-affected communities in Alabama and Joplin, Missouri. Participants completed structured telephone interviews on an average of 8.8 months posttornado. Prior history of IPV was prevalent (36.5%), as was reported history of accidents (25.9%) and prior disaster exposure (26.9%). Negative binomial regression analyses with PTSD and depression symptom counts for past month as outcome variables indicated that history of predisaster IPV was most robustly related to PTSD and depression symptoms, such that those with a history of IPV endorsed over 3 times the number of symptoms than those without IPV history. Final model statistics indicated that female gender, physical injury to caregiver, concern about others' safety, prior disaster, prior accident, and prior IPV exposure were also related to PTSD. Predictors of depression symptoms were similar with the exception that concern about others' safety was not a predictor and age was a predictor in the final model. It is important to evaluate potential additive effects of IPV history in addition to recent disaster exposure variables and to consider such history when developing interventions aimed to reduce or prevent symptoms of PTSD and depression among adolescents recently exposed to disaster.

Post-sexual assault cigarette smoking: Findings from a randomized clinical trial of a video-based intervention.

Sexual assault (SA) is associated with elevated risk for cigarette smoking. The current study tested whether a brief video intervention delivered in the emergency department was effective at reducing smoking following SA. Participants were 233 girls and women (age 15+) who received a SA medical forensic examination (SAMFE) and were randomized to one of three conditions: 1) Prevention of Post-Rape Stress (PPRS), a brief video designed to reduce post-SA psychopathology; 2) Pleasant Imagery and Relaxation Information (PIRI), an active control video involving relaxation training; and 3) treatment as usual (TAU). Among those who participated at baseline, 154 participants completed at least one follow-up at 1.5, 3, and 6 months after the SAMFE. Participants reported the number of days of smoking and the average number of cigarettes smoked per day in the two weeks prior to the sexual assault as well as in the two weeks prior to each follow-up. Two-thirds (68.8%) of participants smoked prior to the SA or during any follow-up. One-fifth of participants who did not smoke prior to the SA smoked at one or more follow-ups. Smoking declined on average over follow-up although TAU was associated with increased initial smoking compared to PPRS; PPRS and PIRI did not differ. SA contributes to increases in smoking and the PPRS, a brief and cost-effective video-based intervention delivered during the SAMFE, can protect against increases in post-SA smoking. Trial registration: NCT01430624.

Prescription Opioid Misuse After a Recent Sexual Assault: A Randomized Clinical Trial of a Video Intervention.

BACKGROUND AND OBJECTIVES: Prescription opioid (PO) misuse is increasing and is associated with overdose. Individuals who experienced a recent sexual assault are at risk for increased substance use, yet limited interventions target PO misuse after sexual assault. The current study examined the efficacy of video interventions on PO misuse after sexual assault. METHODS: Adolescent girls and women (n = 154) were recruited in the context of a sexual assault medical forensic exam in the emergency department. Effects of a prevention of post-rape stress (PPRS) video and a pleasant imagery and relaxation instruction (PIRI) video were compared with treatment as usual (TAU) during a sexual assault medical forensic exam on PO misuse. Participants reported if they had used POs for non-medical purposes since the sexual assault at 1.5 month follow-up. RESULTS: Results from a logistic regression analysis indicated that participants with a prior sexual assault were less likely to misuse prescription opioids 1.5 months after the assault in the PIRI condition compared with TAU. There were no main effects for video condition and no interactions for the PPRS condition on PO misuse. DISCUSSION AND CONCLUSIONS: Providing the PIRI video, or teaching other types of mindfulness or relaxation exercises, may be warranted as a secondary prevention for individuals during the sexual assault medical forensic exam for those with a prior sexual assault history. SCIENTIFIC SIGNIFICANCE: This research provides an initial examination of the impact of mindfulness skills recently after traumatic event exposure on PO misuse. (Am J Addict 2019;28:376-381).

Traumatic Event Exposure, Posttraumatic Stress Disorder, and Sleep Disturbances in a National Sample of U.S. Adults.

Posttraumatic stress disorder (PTSD) is a highly prevalent, debilitating disorder found to develop after exposure to a potentially traumatic event (PTE). Individuals with PTSD often report sleep disturbances, specifically nightmares and insomnia, which are listed within the criteria for PTSD. This research examined prevalence of insomnia and nightmares within a national sample of 2,647 adults (data weighted by age and sex to correct for differences in sample distribution) who had been exposed to one or more PTEs. Prevalence of self-reported sleep disturbance, sleep disturbances by PTE type, and gender differences were examined. All participants completed a self-administered, structured online interview that assessed exposure to stressful events and PTSD symptoms. Among individuals who met DSM-5 criteria for PTSD, a large majority (more than 92%) reported at least one sleep disturbance. Insomnia was relatively more prevalent than PTE-related nightmares among individuals with PTSD and among all PTE-exposed individuals. A higher number of PTEs experienced significantly increased the likelihood of both trauma-related nightmares and insomnia, McFadden's pseudo R2 = .07, p < .001. Women exposed to PTEs were more likely to endorse experience of insomnia, χ2 (1, N = 2,647) = 99.13, p < .001, φ = .194, and nightmares compared to men, χ2 (1, N = 2,648) = 82.98, p < .001, φ = .177, but this gender difference was not significant among individuals with PTSD, ps = .130 and .050, respectively. Differences in sleep disturbance prevalence by PTE type were also examined. Implications for treatment and intervention and future directions are discussed.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Exposición a eventos traumáticos, trastorno de estrés postraumático y trastornos del sueño en una muestra nacional de adultos EXPOSICION AL TRAUMA, TEPT Y SUEÑO El trastorno de estrés postraumático (TEPT) es un trastorno altamente prevalente y debilitante que se desarrolla después de la exposición a un evento potencialmente traumático (EPT). Los individuos con TEPT a menudo reportan alteraciones del sueño, específicamente pesadillas e insomnio, que se enumeran dentro de los criterios para el TEPT. Esta investigación examinó la prevalencia de insomnio y pesadillas en una muestra nacional de 2647 adultos (datos ponderados por edad y sexo para corregir las diferencias en la distribución de la muestra) quienes habían sido expuestos a uno o más EPTs. Se examinó la prevalencia de trastornos del sueño autoinformados, los trastornos del sueño por tipo de EPT y las diferencias de género. Todos los participantes completaron una entrevista estructurada auto-administrada online, que evaluó la exposición a eventos estresantes y los síntomas de TEPT. Entre las personas que cumplieron con los criterios del DSM-5 para el TEPT, una gran mayoría (más de 92%) reportó al menos una alteración del sueño. El insomnio fue relativamente más prevalente que las pesadillas relacionadas con EPT entre individuos con TEPT y entre todos los individuos expuestos a EPT. Un mayor número de los que experimentaron EPT aumentó significativamente la probabilidad de ambos, pesadillas relacionadas a trauma e insomnio, pseudo R2 de McFadden = .07, p <.001. Las mujeres expuestas a los EPT fueron más propensas a respaldar la experiencia de insomnio, χ2 (1, N = 2647) = 99.13, p <.001, φ = .194, y pesadillas en comparación con los hombres, χ2 (1, N = 2648) = 82.98, p <.001, φ = .177, pero esta diferencia de género no fue significativa entre los individuos con TEPT, ps = .130 y .050, respectivamente. También se examinaron las diferencias en la prevalencia de trastornos del sueño por tipo de EPT. Se discuten las implicaciones para el tratamiento y la intervención y las direcciones futuras.

Suicidal ideation among adolescents following natural disaster: The role of prior interpersonal violence.

OBJECTIVE: The current study examined variables, including prior traumatic events, disaster exposure, and current mental health symptomatology, associated with suicidal ideation following experience of a natural disaster. METHOD: Utilizing a sample of 2,000 adolescents exposed to the spring 2011 tornadoes in the areas surrounding Tuscaloosa, Alabama, and Joplin, Missouri, we hypothesized that prior interpersonal violence (IPV), more so than other prior traumatic events or other symptoms, would be associated with suicidal ideation after the disaster. RESULTS: Suicidal ideation was reported by approximately 5% of the sample. Results of binary logistic regression were consistent with hypotheses in that prior IPV exposure emerged as the variable most robustly related to presence of postdisaster suicidal ideation, even accounting for current symptoms (i.e., posttraumatic stress disorder and depression). Moreover, neither prior accident nor prior natural disaster exposure was significantly associated with postdisaster suicidal ideation, suggesting that something specific to IPV may be conferring risk for suicidality. No other variables, including disaster exposure variables or demographic characteristics, emerged as significantly related. CONCLUSIONS: Our results suggest that individuals who have a history of IPV may be particularly vulnerable following experience of additional traumatic events and that for suicide risk, the experience of prior IPV may be more relevant to consider in the aftermath of natural disasters beyond variables related to the index trauma or current symptomatology.

Co-occurrence of Witnessed Parental Violence and Child Physical Abuse from a National Sample of Adolescents.

This study examined the relations between witnessed parental violence (PV) and child physical abuse (CPA) over a one-year period among a nationally representative sample of 2,514 adolescents, ages 12-18. History of witnessed PV (Wave 1) prospectively predicted new experiences (controlling for abuse history) and first experiences of CPA reported at Wave 2. Conversely, history of CPA predicted new experiences of PV, but not first experiences. For adolescents who reported witnessed PV and CPA, witnessed PV preceded CPA in 70% of cases. Most common configuration was single-perpetrator of violence. Additional perpetrator and sequencing configurations are reported. Study findings addressed several limitations in the literature by including use of adolescent report, longitudinal design, inclusion of perpetrator identity, and a nationally representative sample.

Sensation seeking, binge-type eating disorders, victimization, and PTSD in the National Women's Study.

OBJECTIVE: Higher degrees of sensation seeking (SS) are reported in community and clinical samples of individuals with eating disorders with binge-type features (BTEDs), but no reports exist in representative probability samples of adult women. Additionally, SS has been linked to victimization and PTSD, also associated with BTEDs, yet interrelationships between these variables are unexplored. METHODS: A national, probability sample of 3006 adult women (≥18 y/o) completed structured telephone interviews including assessments for victimization, PTSD, bulimia nervosa (BN) and binge eating disorder (BED). The survey included the 6 items of the Disinhibition-Intentions for the Future (DIF) subscale of Zuckerman's Sensation Seeking Scale-VI, which asks how likely participants would be to engage in given activities. Total SS score (TSSS-DIFS) was the sum of the 6 items' scores. Differences among the 3 groups (BN, BED, non-BN/BED) were compared using ANOVA covaried by age and post-hoc t-tests. Multiple regression tested the effects of age, number of victimization experiences (NVE), lifetime PTSD, and BTEDs on TSSS-DIFS. RESULTS: There were significant differences in TSSS-DIFS across BTED diagnoses (p ≤ .001). Participants with BN (p ≤ .002) and those with BED (p ≤ .01) had significantly higher scores than those without BTEDs. These findings persisted in both groups after correcting for NVE and lifetime PTSD. TSSS-DIFS was significantly higher in participants with BTED with PTSD versus those without (p ≤ .025). DISCUSSION: SS traits related to disinhibition occur more commonly in U.S. adult women with BN and BED, even after controlling for NVE and PTSD, which were also associated with higher TSSS-DIFS.

Investigating Longitudinal Associations Between Sexual Assault, Substance Use, and Delinquency Among Female Adolescents: Results From a Nationally Representative Sample.

PURPOSE: Few studies have explored relations among sexual assault and prospective development of high-risk behaviors among adolescent girls. METHODS: The present study examined longitudinal associations among child sexual assault (CSA) and high-risk behaviors (nonexperimental alcohol and drug use; delinquent behavior) in a nationally representative sample of adolescent girls aged 12-17. RESULTS: Using path modeling, findings provided support for the link between CSA and nonexperimental alcohol use, drug use, and delinquent behavior after controlling for demographic characteristics and Time 1 functioning. Additionally, past 6-month post-traumatic stress disorder assessed at Time 1 was significantly associated with CSA and delinquency measured at Time 2, although the indirect effects did not reach traditional levels of significance. CONCLUSIONS: These findings suggest that CSA may potentiate risk for a number of public health problems.
