BACKGROUND Adverse childhood experiences (ACEs), including child abuse and family dysfunction, are linked to leading causes of adult morbidity and mortality. Most prior ACE studies were based on a nonrepresentative patient sample from one Southern California HMO. PURPOSE To determine if ACE exposure increases the risk of chronic disease and disability using a larger, more representative sample of adults than prior studies. METHODS Ten states and the District of Columbia included an optional ACE module in the 2010 Behavioral Risk Factor Surveillance Survey, a national cross-sectional, random-digit-dial telephone survey of adults. Analysis was conducted in November 2012. Respondents were asked about nine ACEs, including physical, sexual, and emotional abuse and household member mental illness, alcoholism, drug abuse, imprisonment, divorce, and intimate partner violence. An ACE score was calculated for each subject by summing the endorsed ACE items. After controlling for sociodemographic variables, weighted AORs were calculated for self-reported health conditions given exposure to zero, one to three, four to six, or seven to nine ACEs. RESULTS Compared to those who reported no ACE exposure, the adjusted odds of reporting myocardial infarction, asthma, fair/poor health, frequent mental distress, and disability were higher for those reporting one to three, four to six, or seven to nine ACEs. Odds of reporting coronary heart disease and stroke were higher for those who reported four to six and seven to nine ACEs; odds of diabetes were higher for those reporting one to three and four to six ACEs. CONCLUSIONS These findings underscore the importance of child maltreatment prevention as a means to mitigate adult morbidity and mortality.

Understanding the link between adverse childhood experiences (ACEs) and sexual victimization (SV) in adulthood may provide important information about the level of risk for adult SV and sexual re-victimization among childhood sexual abuse (CSA) survivors. In the present paper, we explore the relationship between ACEs, including CSA, and SV in adulthood. Data from the CDC-Kaiser ACE Study were used to examine the effect of experiences of early adversity on adult SV. Adult HMO members (n=7,272) undergoing a routine health exam provided detailed information about ACEs that occurred at age 18 or younger and their experiences of SV in adulthood. Analyses revealed that as ACE score increased, so did risk of experiencing SV in adulthood. Each of the ACE variables was significantly associated with adult SV, with CSA being the strongest predictor of adult SV. In addition, for those who reported CSA, there was a cumulative increase in adult SV risk with each additional ACE experienced. As such, early adversity is a risk factor for adult SV. In particular, CSA is a significant risk factor for sexual re-victimization in adulthood, and additional early adversities experienced by CSA survivors may heighten adult SV risk above and beyond the risk associated with CSA alone. Given the interconnectedness among various experiences of early adversity, adult SV prevention actions must consider how other violence-related and non-violence-related traumatic experiences may exacerbate the risk conferred by CSA on subsequent victimization.

Regional Analysis of Self‐Reported Personality Disorder Criteria

Eric Turkheimer; Derek C. Ford; Thomas F. Oltmanns

Building on the theoretical work of Louis Guttman, we propose that the core problem facing research into the multidimensional structure of the personality disorders is not the identification of factorial simple structure but rather detailed characterization of the multivariate configuration of the diagnostic criteria. Dimensions rotated to orthogonal or oblique simple structure are but one way out of many to characterize a multivariate map, and their current near universal application represents a choice for a very particular set of interpretive advantages and disadvantages. We use multidimensional scaling and regional interpretation to investigate the structure of 78 self-reported personality disorder criteria from a large sample of military recruits and college students. Results suggest that the criteria have a three-dimensional radex structure that conforms only loosely to the 10 existing personality disorder (PD) categories. Regional interpretation in three dimensions elucidates several important aspects of PDs and their interrelationships.

Exposure to childhood adversity has an impact on adult mental health, increasing the risk for depression and suicide. Associations between Adverse Childhood Experiences (ACEs) and several adult mental and behavioral health outcomes are well documented in the literature, establishing the need for prevention. The current study analyzes the relationship between an expanded ACE score that includes being spanked as a child and adult mental health outcomes by examining each ACE separately to determine the contribution of each ACE. Data were drawn from Wave II of the CDC-Kaiser ACE Study, consisting of 7465 adult members of Kaiser Permanente in southern California. Dichotomous variables corresponding to each of the 11 ACE categories were created, with ACE score ranging from 0 to 11 corresponding to the total number of ACEs experienced. Multiple logistic regression modeling was used to examine the relationship between ACEs and adult mental health outcomes adjusting for sociodemographic covariates. Results indicated a graded dose-response relationship between the expanded ACE score and the likelihood of moderate to heavy drinking, drug use, depressed affect, and suicide attempts in adulthood. In the adjusted models, being spanked as a child was significantly associated with all self-reported mental health outcomes. Over 80% of the sample reported exposure to at least one ACE, signifying the potential to capture experiences not previously considered by traditional ACE indices. The findings highlight the importance of examining both cumulative ACE scores and individual ACEs on adult health outcomes to better understand key risk and protective factors for future prevention efforts.

Adverse Childhood Experiences (ACEs) such as child abuse are related to poor health outcomes. Spanking has indicated a similar association with health outcomes, but to date has not been considered an ACE. Physical and emotional abuse have been shown in previous research to correlate highly and may be similar in nature to spanking. To determine if spanking should be considered an ACE, this study aimed to examine 1): the grouping of spanking with physical and emotional abuse; and 2) if spanking has similar associations with poor adult health problems and accounts for additional model variance. Adult mental health problems included depressive affect, suicide attempts, moderate to heavy drinking, and street drug use. Data were from the CDC-Kaiser ACE study (N=8316, response rate=65%). Spanking loaded on the same factor as the physical and emotional abuse items. Additionally, spanking was associated with increased odds of suicide attempts (Adjusted Odds Ratios (AOR)=1.37; 95% CI=1.02 to1.86), moderate to heavy drinking (AOR)=1.23; 95% CI=1.07 to 1.41), and the use of street drugs (AOR)=1.32; 95% CI=1.4 to 1.52) in adulthood over and above experiencing physical and emotional abuse. This indicates spanking accounts for additional model variance and improves our understanding of these outcomes. Thus, spanking is empirically similar to physical and emotional abuse and including spanking with abuse adds to our understanding of these mental health problems. Spanking should also be considered an ACE and addressed in efforts to prevent violence.

Do maladaptive behaviors exist at one or both ends of personality traits

In the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; American Psychiatric Association, 2013) personality disorder trait model, maladaptive behavior is located at one end of continuous scales. Widiger and colleagues, however, have argued that maladaptive behavior exists at both ends of trait continua. We propose that the role of evaluative variance differentiates these two perspectives and that once evaluation is isolated, maladaptive behaviors emerge at both ends of nonevaluative trait dimensions. In Study 1, we argue that evaluative variance is worthwhile to measure separately from descriptive content because it clusters items by valence regardless of content (e.g., lazy and workaholic; apathetic and anxious; gullible and paranoid; timid and hostile, etc.), which is unlikely to describe a consistent behavioral style. We isolate evaluation statistically (Study 2) and at the time of measurement (Study 3) to show that factors unrelated to valence evidence maladaptive behavior at both ends. We argue that nonevaluative factors, which display maladaptive behavior at both ends of continua, may better approximate ways in which individuals actually behave.

INTRODUCTION Clinicians require tools to rapidly identify individuals with significant childhood adversity as part of routine primary care. The goal of this study was to shorten the 11-item Behavioral Risk Factor Surveillance System Adverse Childhood Experiences (ACEs) measure and evaluate the feasibility and validity of this shortened measure as a screener to identify adults who have experienced significant childhood adversity. METHODS Statistical analysis was conducted in 2015. ACE item responses obtained from 2011-2012 Behavioral Risk Factor Surveillance System data were combined to form a sample of 71,413 adults aged ≥18 years. The 11-item Behavioral Risk Factor Surveillance System ACE measure was subsequently reduced to a two-item screener by maintaining the two dimensions of abuse and household stressors and selecting the most prevalent item within each dimension. RESULTS The screener included household alcohol and childhood emotional abuse items. Overall, 42% of respondents and at least 75% of the individuals with four or more ACEs endorsed one or both of these experiences. Using the 11-item ACE measure as the standard, a cut off of one or more ACEs yielded a sensitivity of 99%, but specificity was low (66%). Specificity improved to 94% when using a cut off of two ACEs, but sensitivity diminished (70%). There was no substantive difference between the 11-and two-item ACE measures in their strength of association with an array of health outcomes. CONCLUSIONS A two-item ACE screener appropriate for rapid identification of adults who have experienced significant childhood adversity was developed.

BACKGROUND The Short Form Health Survey (SF-36) and the Centers for Disease Control and Prevention (CDC) Healthy Days items are well known measures of health-related quality of life. The validity of the SF-36 for older adults and those with disabilities has been questioned. OBJECTIVE Assess the extent to which the SF-36 and the Centers for Disease Control and Prevention (CDC) Healthy Days items measure the same aspects of health; whether the SF-36 and the CDC unhealthy days items are invariant across gender, functional status, or the presence of chronic health conditions of older adults; and whether each of the SF-36s eight subscales is independently associated with the CDC Healthy Days items. METHODS We analyzed data from 66,269 adult Medicare advantage members age 65 and older. We used confirmatory factor analyses and regression modeling to test associations between the CDC Healthy Days items and subscales of the SF-36. RESULTS The CDC Healthy Days items were associated with the SF-36 global measures of physical and mental health. The CDC physically unhealthy days item was associated with the SF-36 subscales for bodily pain, physical role limitations, and general health, while the CDC mentally unhealthy days item was associated with the SF-36 subscales for mental health, emotional role limitations, vitality and social functioning. The SF-36 physical functioning subscale was not independently associated with either of the CDC Healthy Days items. CONCLUSIONS The CDC Healthy Days items measure similar domains as the SF-36 but appear to assess HRQOL without regard to limitations in functioning.

36.00 oi.org/10.1016/j.amepre.2017.03.015 The field of suicide prevention has had numerous promising advances in recent decades, including the development of evidence-based prevention strategies, the National Suicide Prevention Lifeline (1-800-273-TALK), the Suicide Prevention Resource Center, and a revised National Strategy for Suicide Prevention. Despite these important advances, suicide prevention still lacks the breadth and depth of the coordinated response truly needed to reduce suicide morbidity and mortality. Suicide prevention requires a comprehensive approach that spans systems, organizations, and environments, combining treatment and intervention with primary prevention efforts beginning in childhood so they can set the stage for future health and well-being. Adverse childhood experiences (ACEs), including exposure to child abuse and neglect, are welldocumented risk factors for suicidality, and a viable suicide prevention target; however, suicide prevention efforts seldom focus here. The following provides an overview of suicide prevention and intervention, and suggestions for comprehensive suicide prevention programs that address ACE prevention. The context for suicide prevention in the U.S. is sobering. In 2015, a total of 44,193 individuals died by suicide, and between 1999 and 2015, suicide rates increased more than 25%. Emergency departments recorded 1.4 million discharges for self-inflicted injuries, and acute care hospitals recorded an additional 758,000 discharges in 2013. These numbers represent only a fraction of individuals experiencing suicidal ideation. According to self-report survey data, 1.3 million adults attempted suicide, 2.7 million made plans for suicide, and 9.7 million adults seriously considered suicide in 2015. These events exact a large emotional and human cost on families, friends, workplaces, and communities. Based on conservative estimates, death by suicide totals
