Hallucinatory experiences can occur in both clinical and nonclinical groups. However, in previous studies of the general population, investigations of the cognitive mechanisms underlying hallucinatory experiences have yielded inconsistent results. We ran a large-scale preregistered multisite study, in which general-population participants ( N = 1,394 across 11 data-collection sites and online) completed assessments of hallucinatory experiences, a measure of adverse childhood experiences, and four tasks: source memory, dichotic listening, backward digit span, and auditory signal detection. We found that hallucinatory experiences were associated with a higher false-alarm rate on the signal detection task and a greater number of reported adverse childhood experiences but not with any of the other cognitive measures employed. These findings are an important step in improving reproducibility in hallucinations research and suggest that the replicability of some findings regarding cognition in clinical samples needs to be investigated.

Hallucinatory experiences (HEs) can occur in both clinical and non-clinical groups. However, previous studies of the general population that have investigated cognitive mechanisms underlying HEs have yielded inconsistent results. In this study, we ran a large-scale preregistered multi-site study, in which general population participants (N = 1394, across 11 data collection sites and online) completed assessments of HEs and source memory, dichotic listening, backwards digit span and auditory signal detection tasks, plus a measure of adverse childhood experiences. We found that HEs were associated with a higher false alarm rate on the signal detection task and a greater number of reported adverse childhood experiences, but not with any of the other cognitive measures employed. These findings are an important step in improving reproducibility in hallucinations research and suggest that the replicability of some findings regarding cognition in clinical samples need to be investigated.

AbstractThere is an extensive literature describing the detrimental effects of adverse childhood experiences (ACE; e.g., abuse, neglect, and household dysfunction) on physical and mental health. However, few large-scale studies have explored these associations longitudinally in urban minority cohorts or assessed links to broader measures of well-being such as educational attainment, occupation, and crime. Although adversity and resilience have long been of interest in developmental psychology, protective and promotive factors have been understudied in the ACE literature. This paper investigates the psychosocial processes through which ACEs contribute to outcomes, in addition to exploring ways to promote resilience to ACEs in vulnerable populations. Follow-up data were analyzed for 87% of the original 1,539 participants in the Chicago Longitudinal Study (N = 1,341), a prospective investigation of the impact of an Early Childhood Education program and early experiences on life-course well-being. Findings suggest that ACEs impact well-being in low-socioeconomic status participants above and beyond the effects of demographic risk and poverty, and point to possible mechanisms of transmission of ACE effects. Results also identify key areas across the ecological system that may promote resilience to ACEs, and speak to the need to continue to support underserved communities in active ways.

This study compared sociodemographic characteristics, adverse childhood experiences (ACEs), and substance use and psychiatric disorders between adolescent-limited (AL), adult-onset (AO), life-course-persistent (LP) and nonoffender (NO) groups using a large U.S. general population survey. The odds of experiencing several ACEs were greater among each offender group relative to NOs. LP offenders experience more ACEs than AL and AO offenders. Each offender group generally experienced greater substance use and psychopathology than NOs, whereas LP offenders experienced more substance use and psychopathology than AO and AL offenders. The results of this study identified several sociodemographic factors, ACEs, and types of psychopathology that differentiate AL, AO, LP, and NO offenders that can help inform prevention and intervention strategies designed to prevent offending and shorten criminal careers.

Abstract Background Childhood trauma has long-lasting implications for adult health as prior work in the general population linked ≥4 adverse childhood experiences (ACEs) to multiple negative health outcomes in adulthood. History of childhood trauma is prevalent in people living with HIV (PLWH); however, screening for history of childhood trauma is not routinely performed in HIV clinical care. Methods We conducted a single-center, cross-sectional quality improvement pilot project to (1) define the prevalence of ACEs in PLWH engaged in care and (2) improve linkage with mental health resources. We hypothesized the prevalence of ≥4 ACEs in PLWH would be >21%, the prevalence previously reported in the local, general population. Patients were approached in the course of routine clinical care at an urban, academic HIV outpatient clinic between October 2018 and April 2019 and offered screening for ACEs, depression, and post-traumatic stress disorder (PTSD) using previously validated tools. Results Forty-nine patients completed the screening. Median age was 48 years [IQR: 37–55]; 69% were male and 53% were gay or bisexual. Most patients identified as black/African American (75%) and white (12%). Median ACEs score was 4 [IQR 1–6], with 51% (95% CI: 36–66%) reporting ≥4 ACEs (Figure 1), and most common ACE being guardian substance abuse (57%) (Figure 2). When compared with men, women had a higher median ACEs score (5 vs. 3, P = 0.04), history of childhood sexual abuse (67% vs. 26%, P <0.001), parent incarceration (53% vs. 24%, P = 0.04), and parental divorce or separation (73% vs. 41%, P = 0.04). Patients with ≥4 ACEs were more likely to have positive PTSD screens (56% vs. 21%, P = 0.02), moderate depression or greater (37% vs. 11%, P = 0.002), and were more likely to accept on-site mental health referral after screening (36% vs. 8%, P = 0.04). Acceptability of screening was deemed “very good” by patients, with median acceptability score 5 [IQR: 4–5] on a 5-point scale. Conclusion Over half of HIV+ patients screened in our clinic reported ≥4 ACEs, more than twice the prevalence of the general population. ACEs screening facilitated linkage of patients with high ACEs scores to mental healthcare. These results highlight the potential value of routine ACEs screening to enhance delivery of trauma-informed HIV primary care. Disclosures All authors: No reported disclosures.

Adverse Childhood Experiences (ACEs) are extreme stressors that lead to negative psychosocial outcomes in adulthood. Non-human animals explore less after exposure to early stress. Therefore, in this pre-registered study we hypothesised that reduced exploration following ACEs would also be evident in human adults. Further, we predicted that adults with ACEs, in a foraging task, would adopt a decision-making policy that relies on the most recent reward feedback, a rational strategy for unstable environments. We analysed data from 145 adult participants, 47 with four or more ACEs and 98 with fewer than four ACEs. In the foraging task, participants evaluated the trade-off between exploiting a known patch with diminishing rewards and exploring a novel one with a fresh distribution of rewards. Using computational modelling, we quantified the degree to which participants’ decisions weighted recent feedback. As predicted, participants with ACEs explored less. However, contrary to our hypothesis, they underweighted recent feedback. These unexpected findings might have occurred due to early adversity causing adults exposed to these experiences to use reward feedback less when making decisions. Our results may help to identify cognitive mechanisms that link childhood trauma to the onset of psychopathology.
