Validation of the four-item very brief University of California at Los Angeles Posttraumatic Stress Disorder Reaction Index screening tool for children and adolescents.

OBJECTIVE: Experiencing traumatic events places children and adolescents at risk for developing posttraumatic stress disorder (PTSD), often leading to adverse mental health consequences. Although well-validated measures of PTSD are available, very brief screening tools are needed to assess PTSD when resources are limited. This study was conducted to develop and validate the four-item University of California at Los Angeles (UCLA) PTSD Reaction Index for DSM-5-Very Brief Form (RI-5-VBF) to be used in settings requiring rapid and efficient screening. METHOD: Item response theory (IRT) models were used to derive RI-5-VBF scores from the UCLA PTSD Reaction Index for DSM-5 and assess its internal consistency using a sample of 1,785 youth (Mage = 12.32 years, SD = 2.78) seeking support at an academic medical center clinic or bereavement center. Receiver operating characteristic (ROC) analyses and diagnostic efficiency statistics were used to assess discriminant groups validity and screening utility of the RI-5-VBF scores. Differential item functioning (DIF) analyses were used to examine possible bias across age, gender, race, ethnicity, and clinical setting versus bereavement center setting. RESULTS: IRT models identified four items with the highest discrimination within each PTSD subscale. The RI-5-VBF scores exhibited acceptable internal consistency (α = .74). ROC analyses indicated that an RI-5-VBF score of 9 maximized sensitivity and specificity. DIF analyses did not find evidence of bias across age, gender, race, ethnicity, or clinical versus bereavement center settings. CONCLUSION: These findings provide support for the reliability and validity of the RI-5-VBF. Findings highlight the utility of the RI-5-VBF as a brief screening measure for PTSD in children and adolescents. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Reminder-Focused Positive Psychiatry: Suicide Prevention Among Youths With Comorbid Posttraumatic Stress Disorder and Suicidality.

OBJECTIVE: This study aimed to investigate the effect of brief reminder-focused positive psychiatry and suicide prevention (RFPP-S) on suicidal ideation, posttraumatic stress disorder (PTSD) symptoms, and clinical outcomes among youths with PTSD treated in psychiatric emergency rooms. METHODS: This study included youths with PTSD and suicidality who received either RFPP-S (N=50) or treatment as usual (N=150). The Columbia Suicide Severity Rating Scale (C-SSRS), Clinician-Administered PTSD Scale for children and adolescents, University of California, Los Angeles Trauma Reminder Inventory, Patient Health Questionnaire-9, Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment Scale, and positive psychiatry test batteries were administered at baseline, on day 2, and 1 week and 1 month after discharge. RESULTS: On day 2, the RFPP-S group showed a greater reduction in PTSD symptoms (55%) and reactivity to trauma and loss reminders (80%) compared with the control group (10% for both) (p=0.001). A significantly greater reduction in C-SSRS score for RFPP-S (80%), compared with treatment as usual (15%), was noted (p=0.001), and RFPP-S showed more rapid stabilization (mean±SD=2.0±0.5 days) and enhanced postdischarge follow-up (100%) compared with treatment as usual (5.0±2.0 days and 50%, respectively) (p<0.05). RFPP-S, but not treatment as usual, was associated with significant increases in well-being, flexible thinking, and coping skills (p<0.05). Hospital readmission due to suicidality 1 month after discharge was 0% for the RFPP-S group and 20% for the control group. CONCLUSIONS: RFPP-S was associated with reduced PTSD symptoms, enhanced coping skills while experiencing trauma reminders, adoption of safety skills, rapid stabilization of acute crises of PTSD with suicidality, adherence to post-emergency room visits and treatment, and favorable clinical outcomes.

Identifying Bereavement-Related Markers of Mental and Behavioral Health Problems Among Clinic-Referred Adolescents.

Objective: This study examined bereavement-related risk markers (number of deaths, cause of death, and relationship to deceased) of mental and behavioral health problems (suicidal thoughts or behaviors, self-injury, depression, posttraumatic stress, and substance use) in a national sample of clinic-referred bereaved adolescents. Method: Participants included 1281 bereaved youth aged 12-21 years (M=15, SD=1.8; 62.1% female), from the National Child Traumatic Stress Network Core Data Set. Results: Generalized linear mixed-effects regression models controlling for demographics and other traumas revealed that youth bereaved by multiple deaths had higher posttraumatic stress scores than youth bereaved by a single death (Estimated difference ±SE=3.36 ± 1.11, p=0.003). Youth bereaved by suicide were more likely to report experiencing suicidal thoughts or behaviors (AOR=1.68, p=0.049) and alcohol use (AOR=2.33, p<0.001) than youth bereaved by natural causes. Youth bereaved by homicide were at greater risk for substance use than youth bereaved by natural death (AOR=1.76, p=0.02). Compared to parentally bereaved youth, youth who lost a peer were more likely to use alcohol (AOR=2.32, p=0.02) or other substances (AOR=2.41, p=0.01); in contrast, parentally bereaved youth were more likely to experience depression compared to those who experienced the death of an adult relative or unrelated adult (range of AOR: 0.40 to 0.64, p-values<0.05). Conclusion: These bereavement-related contextual factors can serve as early markers of mental and behavioral health problems among bereaved youth.

Five Essential Elements of Immediate and Mid-Term Mass Trauma Intervention: Empirical Evidence.

Given the devastation caused by disasters and mass violence, it is critical that intervention policy be based on the most updated research findings. However, to date, no evidence-based consensus has been reached supporting a clear set of recommendations for intervention during the immediate and the mid-term post mass trauma phases. Because it is unlikely that there will be evidence in the near or mid-term future from clinical trials that cover the diversity of disaster and mass violence circumstances, we assembled a worldwide panel of experts on the study and treatment of those exposed to disaster and mass violence to extrapolate from related fields of research, and to gain consensus on intervention principles. We identified five empirically supported intervention principles that should be used to guide and inform intervention and prevention efforts at the early to mid-term stages. These are promoting: 1) a sense of safety, 2) calming, 3) a sense of self- and community efficacy, 4) connectedness, and 5) hope.

25-year follow-up of treated and not-treated adolescents after the Spitak earthquake: course and predictors of PTSD and depression.

BACKGROUND: There is a paucity of long-term prospective disaster studies of the psychological sequelae among survivors. METHODS: At 1½ and 25 years after the Spitak earthquake, 142 early adolescents from two cities were assessed: Gumri (moderate-severe exposure) and Spitak (very severe exposure). The Gumri group included treated and not-treated subjects, while the Spitak group included not-treated subjects. Instruments included: DSM-III-R PTSD-Reaction Index (PTSD-RI); DSM-5 PTSD-Checklist (PCL); Depression Self-Rating Scale (DSRS); and Center for Epidemiological Studies-Depression Scale (CES-D). RESULTS: (1) Between 1½ and 25 years, PTSD rates and mean scores decreased significantly in the three groups (over 50%). However, at 25 years 9.1-22.4% met DSM-5 PTSD criteria. (2) At 1½ years, the Spitak group had higher PTSD-RI (p < 0.001) and DSRS scores (p < 0.001) compared to the Gumri-not-treated group. At 25 years, the Spitak group that had experienced fewer post-earthquake adversities (p < 0.03), had a greater decrease in PTSD-RI scores (p < 0.02), and lower CES-D scores (p < 0.01). (3) Before treatment, PTSD-RI and DSRS scores did not differ between the Gumri-treated and not-treated groups. At 25-years, the Gumri-treated group showed a greater decrease in PTSD-RI scores (p < 0.03), and lower mean PTSD-RI (p < 0.02), PCL (p < 0.02), and CES-D (p < 0.01) scores. (4) Predictors of PTSD symptom severity at 25-years included: home destruction, treatment, social support, post-earthquake adversities, and chronic medical illnesses. CONCLUSION: Post-disaster PTSD and depressive symptoms can persist for decades. Trauma-focused treatment, alleviation of post-disaster adversities, improving the social ecology, and monitoring for chronic medical illnesses are essential components of recovery programs.

A Randomized Controlled Feasibility Trial of Reminder-Focused Positive Psychiatry in Adolescents With Comorbid Attention-Deficit/Hyperactivity Disorder and Posttraumatic Stress Disorder.

OBJECTIVE: To investigate the impact of reminder-focused positive psychiatry (RFPP) on attention-deficit/hyperactive disorder (ADHD) and posttraumatic stress disorder (PTSD) symptoms, vascular-function, inflammation and well-being of adolescents with comorbid ADHD and PTSD. METHODS: After obtaining informed-consent, 11 adolescents were randomized to RFPP (n = 5) or trauma-focused cognitive-behavioral therapy (TF-CBT) (n = 6). Eight participants (RFPP: n = 4, TF-CBT: n = 4) completed the twice-weekly intervention for a 6-week trial. The RFPP intervention was inclusive of positive psychiatry interventions on (1) traumatic reminders and (2) avoidance and negative cognition. Vascular function measured as temperature rebound, C-reactive protein, homocysteine, ADHD Swanson, Nolan, and Pelham (SNAP) Questionnaire, Clinician-Administered PTSD Scale for DSM-5-Child/Adolescent Version (CAPS-CA), and neuropsychiatric-measures were measured at baseline and 6 weeks. Subjects were followed for 12 months. The study was conducted from September 2016 to June 2018. RESULTS: A significant improvement in CAPS-CA, SNAP scores, and vascular function of both RFPP and TF-CBT groups was noted at follow-up, but was more-robust in the RFPP group (P < .05). At the sixth week, a significant increase in PERMA, gratitude, resilience, and Posttraumatic Growth Inventory scores and a significant decrease in homocysteine and C-reactive protein levels in the RFPP group, but not the TF-CBT group, were noted (P < .05). At 12-month follow-up, there was no psychiatry hospitalization or suicide ideation reported in either group. A continuation of significant improvement in CAPS-CA and SNAP scores in both groups was noted but was more robust in the RFPP group (P < .05). Similarly, a continuation of significant increase in PERMA, gratitude, resilience and Posttraumatic Growth Inventory scores was noted in the RFPP group but not in the TF-CBT group (P < .05). CONCLUSIONS: RFPP is associated with improvement in core PTSD and ADHD symptoms, decrease in inflammation, and increase in well-being, vascular function, and posttraumatic growth, as well as a favorable long-term clinical outcome. This finding highlights the importance of the dual role of RFPP in addressing vulnerability symptoms as well as enhancing well-being in youth with comorbid ADHD and PTSD.

Measurement Invariance of the Persistent Complex Bereavement Disorder Checklist With Respect to Youth Gender, Race, Ethnicity, and Age.

The Persistent Complex Bereavement Disorder (PCBD) Checklist was constructed to facilitate the developmentally sensitive assessment of proposed PCBD criteria in bereaved children and adolescents 8-18 years of age. Initial analyses of the PCBD Checklist provided support for the hypothesized two-factor model. The purpose of the present study was to evaluate the measurement invariance of the PCBD Checklist with respect to gender (boys and girls), race/ethnicity (White, Black, and Hispanic youth), and age (school age, preadolescent, and adolescent youth). Participants were 594 youth (50.4% female) aged 7-18 years (M = 11.91, SD = 2.80) who were evaluated as part of standard care at a community-based grief support center. Youth self-identified as Hispanic (n = 184, 30.8%), non-Hispanic white (n = 179, 30.0%), and African American/Black (n = 136, 22.8%). A series of stepwise, multigroup confirmatory factor analyses provided evidence in support of the PCBD Checklist's measurement invariance for all three groups concerning configural invariance, metric invariance, and scalar invariance. These results suggest that PCBD Checklist Criterion B and C scores are measuring similar latent variables, to a similar degree, across gender, race/ethnicity, and age. Establishing the cross-group equivalence of the PCBD Checklist is an important endorsement of its generalizability and clinical utility in that it can be administered to diverse populations with confidence that it is measuring proposed PCBC diagnostic criteria similarly across subgroups.

Implementing an emotional support and mental health response plan for healthcare workers during the COVID-19 pandemic.

Institutions across the world are working to develop initiatives aimed at supporting the well-being of healthcare workers (HCWs) facing the psychological impacts of the novel coronavirus (COVID-19) pandemic. This Commentary identifies risks that HCWs are experiencing, reviews sources of fear and stress, and describes the implementation of a three-tiered model for the provision of emotional support and mental health services for clinical and nonclinical HCWs. The model recognizes the fluid, ever-evolving nature of the COVID-19 pandemic and includes proactive, visible, and easy-to-access supportive psychological services that expand the safety net and help address immediate and future mental health challenges of HCWs.

Validation of the UCLA PTSD Reaction Index for DSM-5: A Developmentally Informed Assessment Tool for Youth.

OBJECTIVE: To describe the test construction procedure and evaluate the internal consistency, criterion-referenced validity, and diagnostic accuracy of the Child/Adolescent Self-Report Version of the UCLA PTSD Reaction Index for DSM-5 (RI-5) across 2 independent samples. METHOD: Study 1 examined the clarity, developmental appropriateness, acceptability of individual RI-5 items, and internal consistency and criterion-referenced validity of the full test. The study 1 sample included 486 youth recruited from 2 major US cities who completed the RI-5 and a measure of depression. Study 2 evaluated the reliability and diagnostic accuracy of the RI-5 in 41 treatment-seeking youth who completed the RI-5 and a "gold standard" structured diagnostic interview, the Clinician-Administered PTSD Scale for DSM-5-Child/Adolescent Version. RESULTS: RI-5 total scale scores showed excellent internal consistency in the 2 samples. Study 1 provided evidence of criterion-referenced validity, in that total scale scores correlated positively with depressive symptoms. Study 2 provided evidence of diagnostic accuracy (including discriminant-groups validity). RI-5 total scores discriminated youth with from youth without PTSD as benchmarked against the structured diagnostic interview. Further, receiver operating characteristic analyses using a total score of 35 provided excellent diagnostic classification accuracy (area under the curve 0.94). CONCLUSION: The developmental appropriateness and diagnostic accuracy of the RI-5 support its utility for clinical assessment, case conceptualization, and treatment planning in different child-serving systems, including schools, juvenile justice, child welfare, and mental health.

Trauma-informed measurement-based care for children: Implementation in diverse treatment settings.

Ongoing and comprehensive assessment is a critical part of the implementation of evidence-based care; yet, most providers fail to routinely incorporate measurement into their clinical practice. Few studies have focused on the complex application of routine assessment or measurement-based care (MBC) with children. This pilot examined the acceptability, appropriateness, adoptability, and feasibility of an MBC effort, the Clinical Improvement through Measurement Initiative (CIMI), across several child-serving settings (e.g., community mental health center, residential treatment facility). CIMI includes a comprehensive mental health assessment protocol and combines a mobile technology platform with implementation support. Survey and focus group information, assessing implementation constructs and outcomes, was collected from 44 clinicians and staff. Overall, participants agreed that the implementation process and technology were acceptable, appropriate, and feasible for use in child mental health and that CIMI can be used to guide case conceptualization, facilitate treatment planning, and monitor outcomes. Strategies that supported the implementation process were identified as were recommendations to enhance adoption. Significant differences were observed by Community versus Specialized settings with respect to feasibility and appropriateness, likely because of factors associated with inner setting (climate, compatibility), outer setting (patient needs), and the phase of implementation achieved by sites. Implications and recommendations for tailoring MBC implementation by characteristics related to setting are discussed. MBC across child service settings are discussed in the context of implementation frameworks. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

The UCLA PTSD Reaction Index for DSM-5 Brief Form: A Screening Tool for Trauma-Exposed Youths.

OBJECTIVE: Children and adolescents who experience potentially traumatic events are at risk for developing posttraumatic stress disorder (PTSD). Although psychometrically sound measures are now available to assess these youths, brief tools are currently needed for screening purposes. Two studies were conducted to develop and validate the UCLA PTSD Reaction Index for DSM-5-Brief Form (RI-5-BF). METHOD: Study 1 used item response theory models to derive the RI-5-BF from the UCLA PTSD Reaction Index for DSM-5 and assess its internal consistency using a sample of 486 trauma-exposed youths (mean age = 13.32 years, SD = 2.90) recruited through a practice research network. Study 2 used receiver operating characteristic analyses and diagnostic efficiency statistics to assess the discriminant-groups validity and clinical utility of the RI-5-BF in identifying children at different levels of PTSD risk using a sample of 41 treatment-seeking youths (mean age = 12.44 years, SD = 2.99). RESULTS: In study 1, item response theory models identified the 11 most informative items across their respective subscales. The RI-5-BF exhibited excellent internal consistency in both studies (α > .93). In study 2, receiver operating characteristic analyses indicated that an RI-5-BF score of 21 maximized sensitivity and specificity. Moreover, diagnostic likelihood ratios across multiple levels of scores provided support for the measure's clinical utility in identifying different levels of PTSD risk. CONCLUSION: These findings provide support for both the psychometric properties of the RI-5-BF as a brief screening measure for PTSD in children and adolescents and its utility for identifying youths meriting further assessment and consideration for treatment.

Pediatrician's Practical Approach to Sleep Disturbances in Children Who Have Experienced Trauma.

Sleep difficulties are a common challenge among children who have experienced trauma. Pediatricians are best positioned to work with families to address sleep challenges after traumatic events and help families return to healthy sleep patterns. In this article, we review the underlying concepts that connect trauma to disturbed sleep, types of sleep difficulties seen in children exposed to trauma, and explore ways in which pediatricians can support families as they help their child return to a normal sleep cycle, including the identification of co-occurring conditions and the use of medications.

Benefits of Treatment Completion Over Premature Termination: Findings from the National Child Traumatic Stress Network.

Objective: To evaluate potential differences in therapeutic outcomes between youths who completed a full course of treatment as planned compared to youths who terminated treatment prematurely. Method: Using longitudinal data from the National Child Traumatic Stress Network (NCTSN) Core Data Set, the present study examined demographic characteristics, trauma history, scores on standardized measures, and ratings of functional impairment and behavior problems in a large clinical sample of children and adolescents exposed to trauma who received treatment at NCTSN centers across the United States. Baseline and follow-up data were used to compare treatment completers (n= 3,108) and noncompleters (n = 4,029). Results: Both treatment completers and noncompleters received benefits from treatment by NCTSN mental health providers in that both groups showed significant decreases in mean scores from baseline to follow-up on all standardized measures. However, compared to noncompleters, treatment completers showed three types of significantly greater benefit at follow-up. These included: (a) greater rates of decline (i.e., steeper slopes) on all outcome measures; (b) greater reductions in the odds of falling within the clinical range on standardized measures; and (c) greater reductions in the odds of exhibiting functional impairment and behavior problems at follow-up. In contrast, compared to treatment completers, noncompleters reported significantly higher rates of lifetime exposure to community violence, psychological maltreatment, physical abuse, neglect, sexual abuse, and sexual assault. Conclusion: These findings underscore the value of incorporating engagement and retention strategies in treatments for traumatized youths to maximize therapeutic benefit and raise the standard of care.

Evaluating referral, screening, and assessment procedures for middle school trauma/grief-focused treatment groups.

There is a need to delineate best practices for referring, assessing, and retaining students suspected of posttraumatic stress (PTS) and maladaptive grief (MG) in school-based treatment. Evidence-based risk-screening procedures should accurately include students who are appropriate for group treatment and exclude students who do not require treatment or who are better served by other forms of intervention and support. We described and evaluated the sequence of steps used to screen 7th- and 8th-grade students (N = 89) referred by school staff as candidates for an open trial of group-based Trauma and Grief Component Therapy for Adolescents (TGCTA; Saltzman et al., in press). We used t tests to compare included versus excluded students on PTS symptom and MG reaction scores (University of California at Los Angeles Posttraumatic Stress Disorder Reaction Index; Grief Screening Scale) during the group screen, individual interview, and treatment-implementation phases. Logistic regressions tested the incremental utility of including measures of both trauma exposure and related emotional and conduct problems (Strengths and Difficulties Questionnaire) in the screening battery. Results suggest that the group screen helped to detect mental health needs and that the individual interview further identified students with PTS and emotional problems. Conduct problems and trauma exposure predicted attrition among students who qualified for treatment. MG incrementally predicted students who advanced from the group screening to the individual interview, and trauma exposure incrementally predicted attrition from treatment. Findings yield implications for improving research and practice, including procedures for enhancing school-based referral, screening, assessment, and selection procedures. (PsycINFO Database Record

Validation of the Persistent Complex Bereavement Disorder (PCBD) Checklist: A Developmentally Informed Assessment Tool for Bereaved Youth.

The inclusion of Persistent Complex Bereavement Disorder (PCBD) in the DSM-5 appendix signifies a call for research regarding the distinguishing features and clinical utility of proposed PCBD criteria. Rigorously constructed tools for assessing PCBD are lacking, especially for youth. This study evaluated the validity and clinical utility of the PCBD Checklist, a 39-item measure designed to assess PCBD criteria in youth aged 8 to18 years. Test construction procedures involved: (a) reviewing the literature regarding developmental manifestations of proposed criteria, (b) creating a developmentally informed item pool, (c) surveying an expert panel to evaluate the clarity and developmental appropriateness of candidate items, (d) conducting focus groups to evaluate the comprehensibility and acceptability of items, and (e) evaluating psychometric properties in 367 bereaved youth (Mage = 13.49, 55.0% female). The panel, clinicians, and youth provided favorable content validity and comprehensibility ratings for candidate items. As hypothesized, youth who met full PCBD criteria, Criterion B (e.g., preoccupation with the deceased and/or circumstances of the death), or Criterion C (e.g., reactive distress and/or social/identity disruption) reported higher posttraumatic stress and depressive symptoms than youth who did not meet these criteria, ηp2 = .07-.16. Youth who met Criterion C reported greater functional impairment than youth who did not, ηp2 = .08-.12. Youth who qualified for the "traumatic bereavement specifier" reported more frequent posttraumatic stress symptoms than youth who did not, ηp2 = .04. Findings support the convergent, discriminant, and discriminant-groups validity, developmental appropriateness, and clinical utility of the PCBD Checklist.

The Long-Term Clinical Outcome of Posttraumatic Stress Disorder With Impaired Coronary Distensibility.

OBJECTIVE: Coronary Distensibility Index (CDI) impairments reflect endothelial-dependent process associated with vulnerable-plaque composition. This study investigated the relation of impaired CDI with posttraumatic stress disorder (PTSD) and their predictive value for major adverse cardiovascular events (MACE). METHODS: This study involved 246 patients (age = 63 [10] years, 12% women) with (n = 50) and without (n = 196) PTSD, who underwent computed tomography angiography to determine coronary artery disease and CDI. Extent of coronary artery disease was defined as normal, nonobstructive (<50% luminal stenosis), and obstructive (>50%). Incidence of MACE, defined as myocardial infarction or cardiovascular death, was documented during a mean follow-up of 50 months. Survival regression was employed to assess the longitudinal association of impaired CDI and PTSD with MACE. RESULTS: A significant inverse correlation between CDI and Clinical Global Impression Severity scale of PTSD symptoms was noted (r = .81, p = .001). CDI was significantly lower in patients with PTSD (3.3 [0.2]) compared with those without PTSD (4.5 [0.3]), a finding that was more robust in women (p < .05). Covariate-adjusted analyses revealed that the relative risk of MACE was higher in patients with PTSD (hazard ratio [HR] = 1.56, 95% CI = 1.34-3.14) and those with impaired CDI (HR = 1.95, 95% CI = 1.27-3.01, per standard deviation lower CDI value). There was also a significant interaction between PTSD and impaired CDI (HR = 3.24, 95% CI = 2.02-5.53). CONCLUSIONS: Impaired CDI is strongly associated with the severity of PTSD symptoms. Both impaired CDI and PTSD were independently associated with an increased risk of MACE during follow-up, and evidence indicated an interaction between these two factors. These findings highlight the important role of CDI in identifying individuals with PTSD at risk for MACE.

Civilization and its discontented: Links between youth victimization, beliefs about government, and political participation across seven American presidencies.

Promoting trust in public officials and active political engagement is vital to sustaining a well-functioning democracy. Developmental psychologists propose that youths' beliefs about government and participation in politics are rooted in personal experiences within their communities. Previous studies have focused on how positive experiences within youths' families, schools, and communities facilitate greater social trust and political participation. However, less is known about how negative interpersonal experiences-such as criminal victimization-intersect with youths' beliefs about the trustworthiness, competence, and knowledge of government officials, and their participation in political activity. Using data from 39 waves of the Monitoring the Future study, the current study examined associations among youth victimization, beliefs about government, and participation in various political activities. Adolescents (N = 109,574; 50.9% female) enrolled in 12th grade across the United States reported on whether they had experienced various types of victimization during the previous year, their beliefs about government, and their participation in multiple forms of political activity. Adolescents who reported more frequent victimization experiences endorsed significantly greater discontent with government and were significantly more engaged in various forms of political activity. The magnitude and direction of these effects were generally consistent across different types of victimization, different demographic subgroups of youth, and different sociohistorical periods. Findings are interpreted from a social contract theory perspective, followed by a discussion of implications for building psychological theory and informing public policy. (PsycINFO Database Record

Impaired Caregiving, Trauma Exposure, and Psychosocial Functioning in a National Sample of Children and Adolescents.

Impairments in Caregiving (ICG) secondary to mental illness and substance use have been linked to adverse outcomes in children. Little is known, however, about whether outcomes vary by type of ICG, exposure to co-occurring traumas, or mechanisms of maladaptive outcomes. Clinic-referred youth age 7-18 years (n = 3988) were compared on ICG history, demographics, trauma history, and mental health symptoms. Child trauma exposure was tested as a mediator of ICG and child symptoms. Youth with ICG were at heightened risk for trauma exposure, PTSD, internalizing symptoms, total behavioral problems, and attachment problems, particularly youth with multiple types of ICG. Effect sizes were moderate to large for PTSD, internalizing symptoms, and total behavioral problems. Number of trauma types mediated the relationship between ICG and child symptoms. ICG was related to trauma exposure within and outside the family context. Understanding these links has important implications for interrupting intergenerational trauma and psychopathology.
