Background: Adverse childhood experiences (ACEs) have been associated with poor mental and somatic health. Accumulating evidence indicates that accelerated biological aging—indexed by altered telomere-related markers—may contribute to associations between ACEs and negative long-term health outcomes. Telomeres are repeated, non-coding deoxyribonucleic acid (DNA) sequences at the end of chromosomes. Telomeres shorten during repeated cell divisions over time and are being used as a marker of biological aging. Objectives: The aim of the current paper is to review the literature on the relationship between ACEs and telomere length (TL), with a specific focus on how the heterogeneity of sample and ACEs characteristics lead to varying associations between ACEs and TL. Methods: Multiple databases were searched for relevant English peer-reviewed articles. Thirty-eight papers were found to be eligible for inclusion in the current review. Results: Overall, the studies indicated a negative association between ACEs and TL, although many papers presented mixed findings and about a quarter of eligible studies found no association. Studies with smaller sample sizes more often reported significant associations than studies with larger samples. Also, studies reporting on non-clinical and younger samples more often found associations between ACEs and TL compared to studies with clinical and older samples. Reviewing the included studies based on the “Stressor Exposure Characteristics” recently proposed by Epel et al. ( 2018 ) revealed a lack of detailed information regarding ACEs characteristics in many studies. Conclusion: Overall, it is difficult to achieve firm conclusions about associations of ACEs with TL due to the heterogeneity of study and ACE characteristics and the heterogeneity in reported findings. The field would benefit from more detailed descriptions of study samples and measurement of ACEs.
While children and adolescents placed in child welfare or juvenile justice out-of-home care show higher prevalence rates of mental disorders compared to the general population, it remains unclear whether this pattern persists into adulthood. A quantitative synthesis of existing studies is lacking. The aim of this meta-analysis was to estimate the prevalence rates for mental disorders among adults with a foster or residential child welfare or juvenile justice care history, comparing them where possible to rates among the general population. PubMed, PsycInfo, EMBASE, and Web of Science were systematically searched for epidemiological studies published up to 28 October 2020. Nineteen studies, totaling 604,257 participants, met our inclusion criteria. Random-effects models were used for prevalence rates and odds ratios (OR) of mental disorders, and study quality was rated. A prevalence rate of 30% [95% CI (23.36, 37.36)] for any mental disorder in adults with a child welfare care history was found (3–17% for specific disorders). A prevalence rate of 45% [95% CI (42.38, 47.38)] for any mental disorder was found in adults with a juvenile justice care history (6–66% for specific disorders). For out-of-home placement history, adult mental disorders were significantly higher than in the general population (OR = 1.33–2.76). Studies differed in terms of methodology and the disorder groups considered, so heterogeneity between effect sizes ranged from low to high. Our findings suggest that the high risk that mental health issues will persist in adults with an out-of-home placement history needs to be taken seriously in the transition from adolescence to adulthood. The care systems involved need to collaborate and to be aware of these risks.
BackgroundWith the implementation of the 11th edition of the International Classification of Diseases (ICD-11) in early 2022, there will be a radical change in the framework and process for diagnosing personality disorders (PDs), indicating a transition from the categorical to the dimensional model. Despite increasing evidence that PDs are not as stable as previously assumed, the long-term stability of PDs remains under major debate. The aim of the current paper was to investigate the categorical and dimensional mean-level and rank-order stability of PDs from adolescence into young adulthood in a high-risk sample.MethodsIn total, 115 young adults with a history of residential child welfare and juvenile-justice placements in Switzerland were included in the current study. PDs were assessed at baseline and at a 10-year follow-up. On a categorical level, mean-level stability was assessed through the proportion of enduring cases from baseline to follow-up. Rank-order stability was assessed through Cohen’s κ and tetrachoric correlation coefficients. On a dimensional level, the magnitude of change between the PD trait scores at baseline and at follow-up was measured by Cohen’s d. Rank-order stability was assessed through Spearman’s ρ.ResultsThe prevalence rate for any PD was 20.0% at baseline and 30.4% at follow-up. The most frequently diagnosed disorders were antisocial, borderline, and obsessive-compulsive PDs, both at baseline and at follow-up. On a categorical level, the mean-level stability of any PD was only moderate, and the mean-level stability of specific PDs was low, except of schizoid PD. Likewise, the rank-order stability of any PD category was moderate, while ranging from low to high for individual PD diagnoses. On a dimensional level, scores increased significantly for most PDs, except for histrionic traits, which decreased significantly from baseline to follow-up. Effect sizes were generally low. The rank-order stability for dimensional scores ranged from low to moderate.ConclusionThe findings indicate low to moderate stability of Pds and Pd traits from adolescence to adulthood, which supports the growing evidence that categorical diagnoses of Pds are quite unstable. This in turn, emphasizes the use of the upcoming ICD-11 that Acknowledgments Pds to be only “relatively” stable.
Despite high rates of adverse childhood experiences (ACEs) and personality-related disturbances among delinquent juveniles, associations among ACEs, youth personality, and juvenile crime involvement are still unclear. High-risk samples of institutionalized youth are in specific need of a comprehensive assessment of ACEs and personality features in order to broaden the current knowledge on the occurrence and persistence of juvenile crime and to derive implications for prevention and intervention. We examined a heterogeneous high-risk sample of 342 adolescents (35.1% females, 64.9% males) aged between 12 and 18 years (M = 15.74, SD = 1.61 years) living in child-welfare or juvenile justice institutions regarding cumulative ACEs, psychopathic traits, temperament, and clinical personality disorder ratings, and criminal involvement before and up to 10 years after assessment. We found considerable rates of ACEs, although cumulative ACEs did not predict future crime. Latent Profile Analysis based on dimensional measures of psychopathy, temperament, and personality disorders derived six distinct personality profiles, which were differently related to ACEs, personality disturbances, clinical psychopathology, and future delinquency. A socially difficult personality profile was associated with increased risk of future crime, whereas avoidant personality traits appeared protective. Findings indicate that the role of ACEs in the prediction of juvenile delinquency is still not sufficiently clear and that relying on single personality traits alone is insufficient in the explanation of juvenile crime.
Background While the psychopathological sequalae of childhood maltreatment are widely acknowledged, less is known about the underlying pathways by which childhood maltreatment might lead to an increased risk for mental health problems. Recent studies indicated that impaired personality functioning might mediate this relationship. The aim of the present paper was to extend the current literature by investigating the mediating effect of impaired personality functioning between different types of childhood maltreatment and self-reported mental health problems in a high-risk sample. Methods Overall, 173 young adults (mean age = of 26.61 years; SD = 3.27) with a history of residential child welfare and juvenile justice placements in Switzerland were included in the current study. The Childhood Trauma Questionnaire (CTQ-SF), Semi-structured Interview for Personality Functioning DSM-5 (STiP-5.1) and the self-report questionnaires of the Achenbach System of Empirically Based Assessment scales (ASEBA) were used. Mediation analyses were conducted through structural equation modeling. Results Overall, 76.3% (N = 132) participants indicated at least one type of childhood maltreatment, with emotional neglect being most commonly reported (60.7%). A total of 30.6% (N = 53) participants self-reported mental health problems. Emotional abuse (r = 0.34; p < .001) and neglect (r = 0.28; p < .001) were found to be most strongly associated with mental health problems. In addition, impaired personality functioning was fond to be a significant mediator for overall childhood maltreatment (β = 0.089; p = 0.008) and emotional neglect (β = 0.077; p = 0.016). Finally, impaired self-functioning was found to be a significant mediator when both self-functioning and interpersonal functioning were included as potential mediators in the relationship between overall childhood maltreatment (β1 = 0.177, p1 = 0.007) and emotional neglect (β1 = 0.173, p1 = 0.003). Conclusion Emotional neglect may be particularly important in the context of childhood maltreatment, personality functioning, and mental health problems and, therefore, should not be overlooked next to the more “obvious” forms of childhood maltreatment. Combining interventions designed for personality functioning with trauma-informed practices in standard mental health services might counteract the psychopathological outcomes of maltreated children and adolescents.
Zusammenfassung. Theoretischer Hintergrund: Eine Reihe von Studien zeigen soziale Folgen von Misshandlung und Vernachlässigung in der Kindheit im weiteren Lebenslauf. Fragestellung: Diese Studie zielt darauf ab, die langfristigen Auswirkungen von Misshandlungs- und Vernachlässigungserfahrungen auf die soziale Teilhabe in einer Stichprobe von ehemals fremdplatzierten jungen Erwachsenen in der Schweiz zu untersuchen. Methode: Im Rahmen der Studie wurden 218 ehemals fremdplatzierte junge Erwachsene ( MAlter=26.1, 32.6 % weiblich) mit einer psychometrischen Testbatterie befragt. Dabei wurden Misshandlungserfahrungen in der Kindheit erfasst sowie die soziale Teilhabe bezüglich psychischer Gesundheit, Legalbewährung, sozio-ökonomische Lage und Beziehungen untersucht. Ergebnisse: Die Ergebnisse zeigen die hohe Prävalenz und negativen Folgen von kumulierten Misshandlungserfahrungen bei ehemals fremdplatzierten jungen Menschen. Eine höhere Anzahl von Misshandlungserfahrungen ging mit signifikant mehr Problemen in gesundheitlichen, finanziellen und sozialen Lebensbereichen einher. Diskussion und Schlussfolgerung: Die gravierenden Folgen von Misshandlungserfahrungen in der Kindheit unterstreichen die Bedeutung der Prävention und frühzeitigen Intervention. Sie zeigen aber auch, dass viele schwer betroffene junge Menschen neben therapeutischen auch konkrete und lebensweltorientierte Hilfen benötigen, um ihre Entwicklungsaufgaben adäquat zu bewältigen und erfolgreich an der Gesellschaft teilzuhaben.
Zusammenfassung. Theoretischer Hintergrund: Fremdplatzierte Kinder und Jugendliche sind psychisch hoch belastet, jedoch ist der Verlauf von psychischen Problemen bis in deren Erwachsenenalter weitgehend unbekannt. Fragestellung: Die Prävalenz und der Verlauf von psychischen Problemen bei fremdplatzierten Kindern und Jugendlichen bis ins Erwachsenenalter wurden in dieser Studie untersucht und mögliche Prädiktoren identifiziert. Methode: 164 Kinder und Jugendliche wurden während der Fremdplatzierung und im Erwachsenenalter längsschnittlich mittels Selbstbeurteilungsfragebogen auf psychische Gesamtauffälligkeit, internalisierende und externalisierende Probleme untersucht. Ergebnisse: 62.2 % der Kinder und Jugendlichen zeigten auffällige Werte für die Gesamtauffälligkeit wohingegen es im Erwachsenenalter noch 35.7 % waren. Die stärksten Prädiktoren für die jeweiligen Skalen im Erwachsenenalter waren die psychischen Probleme im Kindes- und Jugendalter. Mädchen zeigten eine erhöhte Wahrscheinlichkeit für internalisierende Probleme im Erwachsenenalter im Vergleich zu Jungen. Diskussion und Schlussfolgerung: Die psychischen Probleme bei fremdplatzierten Kindern und Jugendlichen verringerten sich bis ins junge Erwachsenenalter, dennoch blieb ein beachtlicher Teil chronisch auffällig. Implikationen für die Forschung und Praxis werden diskutiert.
According to Cloninger’s model, personality is conceptualized in temperament and character traits contributing to a child’s psychosocial development. Additionally, parent–child interaction is important for the child’s socio-emotional development. To date, the relationship between attachment and temperament and character for child mental health development and its effects on parents remains mostly unclear. The aim of the present study was thus to examine the relationship of attachment, temperament and character, parental stress, and mental health problems among 125 children (mean age = 7.14 years) in Switzerland. Temperament and character, attachment disorder (symptoms), parental stress, and mental health problems were assessed with psychometric questionnaires; attachment was assessed with an additional observational measure. Descriptive characters of the sample were presented, and group differences and correlations were computed. For temperament traits, results revealed significant group differences for novelty seeking and persistence and attachment disorder types. For character traits, the findings showed significant group differences for self-directedness and cooperativeness and attachment disorder types. Moderate effect sizes for groups differences were found. Further, the mixed-type (inhibited and disinhibited) and inhibited attachment disorder type were the most burdened groups. The present findings suggest that temperament and character traits, as well as parental stress and mental health problems are associated with the occurrence of attachment disorders among children. Future longitudinal studies with larger samples are needed to examine the causal relationships of temperament and character with attachment, including person-related and environmental factors among children.
