Sleep and childhood maltreatment: A matched-control study of sleep characteristics in Norwegian 16-19-year-olds.

Sleep problems are an important but understudied health problem in adolescents exposed to childhood maltreatment. The current study aimed to examine sleep characteristics and insomnia in a population with maltreatment history and compare them to a general population sample of adolescents. Data from a sample of Norwegian 16-19-year-old adolescents with childhood maltreatment experiences (n = 62) were linked to an age- and sex-matched general population sample (n = 238). Independent samples t tests were used to compare the two groups on several detailed sleep parameters, while general linear models were used to control for mental health problems, assessed by the Strengths and Difficulties Questionnaire. Mental health was examined as a potential mediator between childhood maltreatment and sleep characteristics. Adolescents exposed to childhood maltreatment had longer sleep onset latency (1:15 h vs. 47 min, p < 0.001), longer wake after sleep onset (34 min vs. 15 min, p < 0.003), lower sleep efficiency in weekdays (77.8%, vs. 85%, p < 0.007), and lower sleep efficiency in weekends (81.8% vs. 88.9%, p < 0.001) than the reference group. Mental health problems fully mediated the association between childhood maltreatment exposure and longer sleep onset latency and wake after sleep onset. The rate of insomnia did not significantly differ between the groups. This study suggests that older adolescents exposed to childhood maltreatment have more sleep problems than the general adolescent population, and that these problems may be explained by co-existing mental health problems. These findings highlight the potential utility of assessing and providing sleep-focused treatment to adolescents with a history of childhood maltreatment and mental health problems.

Study protocol: the Norwegian Triple-S Cohort Study - establishing a longitudinal health survey of children and adolescents with experiences of maltreatment.

BACKGROUND: Child maltreatment is prevalent and associated with both short- and long-term health problems. Previous studies have established child maltreatment as a risk factor for a wide range of problems over the life course such as mental- and somatic health problems, self-harm, alcohol- and drug abuse and decreased work-life participation. Still, there are few large and well-conducted longitudinal studies focusing on describing prevalence and identifying risk factors and long-term consequences of child maltreatment. The purpose of the current study is to recruit a large number of children and adolescents exposed to maltreatment and follow them long-term. METHODS/DESIGN: The current study is a longitudinal cohort study and will use a multi-informant design (child/adolescent, caregiver, and administrative data). Participants will be recruited from the Stine Sofie Centre (SSC), a learning and coping centre for children and adolescents (≤18 years) exposed to maltreatment, which includes physical and emotional abuse, neglect and/or sexual abuse. Questionnaire-based assessments from self-reports (as well as parent-reports) will be carried out at regular time intervals throughout their lives, on topics such as abuse, negative life events, mental and somatic health problems, resilience and coping, satisfaction with health services, social-, family-, and school function, as well as self-harm and substance abuse. Participants will be assessed upon entry to the centre and followed up annually until they reach 18 years and bi-annually after. Given written consent, participants' responses will be linked to relevant national registries in order to examine predictive factors and important outcomes in terms of subsequent health, education, criminal records and work affiliation. DISCUSSION: This study will examine short- and long-term consequences of child maltreatment across a range of health-related outcomes in a longitudinal perspective. Results from the current study might have implications for the development of preventive and intervention programs related to child maltreatment and the organization and follow-up of the services these children receive. The current study will hopefully contribute with knowledge of risk-factors, short- and long-term health-related and other issues that can contribute to practices aimed at improving the overall life-course for children and adolescents who have experienced childhood maltreatment.

Childhood maltreatment and adult mental health.

BACKGROUND: The relationship between reported childhood maltreatment and general psychological and post-traumatic distress was examined in a sample of 551 adults from different risk samples. AIMS: Exposure to childhood maltreatment was assessed using the Childhood Trauma Questionnaire Short Form, which detects physical, emotional and sexual abuse and past physical and emotional neglect. METHODS: The participants' current levels of post-traumatic stress symptoms and general psychological stress symptoms were measured with the Impact of Event Scale - Revised and the Symptom Checklist 90 - Revised, respectively. RESULTS: The results reveal a high prevalence of reported childhood maltreatment in both men and women, and the severity levels of the five types of childhood maltreatment showed significant associations with the extent of current post-traumatic and general psychological distress. CONCLUSION: The findings emphasize the need for appropriate procedures for identifying childhood maltreatment.

Psychometric properties of the Norwegian version of the Childhood Trauma Questionnaire in high-risk groups.

The Childhood Trauma Questionnaire--Short Form (CTQ-SF) is widely used to measure childhood abuse of all types. In the present study, we examined the psychometric properties of the Norwegian version of the instrument. The participants constituted four subsamples (n = 517): substance abusers (n = 126), psychiatric patients (n = 210), prisoners (n = 109) and adolescents in out-of-home placements (n = 72). Confirmatory factor analysis revealed a reasonable fit of the data to the original five-factor structure of the CTQ-SF. Measurement invariance was found across gender and the four subsamples. It was concluded that the Norwegian version of the CTQ-SF has acceptable psychometric properties, with good reliability and satisfactory accuracy, to assess different dimensions of childhood trauma.

Childhood maltreatment and sleep in children and adolescents: A systematic review and meta-analysis.

Childhood maltreatment is a global problem with the risk of serious health consequences for children and adolescents, including sleep problems. Former systematic reviews have examined the association between childhood maltreatment and sleep problems in adults, but no systematic review has investigated the literature on childhood maltreatment and sleep problems in childhood and adolescence. We published a protocol (PROSPERO: CRD42021225741) and conducted a systematic literature search using nine electronic databases. Upon duplicate removal, 1530 records were screened against the inclusion criteria, and 26 studies were included in the review. The most studied sleep outcomes were symptoms of insomnia, sleep duration and nightmares. The results showed significant associations between exposure to childhood maltreatment and insomnia symptoms (OR 3.91, 95%CI: 2.64-5.79, p < .001), shorter sleep duration (-12.1 min, 95%CI: -19.4 to -4.7, p < .001) and nightmares (OR 3.15, 95%CI: 2.38-4.18, p < 001). There was a considerable heterogeneity in measures and instruments used to examine sleep and maltreatment. Our findings highlight the importance of screening and intervening for sleep problems in children and adolescents exposed to childhood maltreatment.

Adverse Childhood Experiences Among 28,047 Norwegian Adults From a General Population.

Aim: The purpose of this study was to estimate the prevalence of adverse childhood experiences (ACEs) among Norwegian adults from a general population and to identify potential associations with demographic and socioeconomic characteristics. Methods: A randomly drawn sample (N = 61,611) from the public registry of inhabitants was invited to participate in the Norwegian Counties Public Health Survey. The present study was based on online responses from 28,047 adults ≥18 years (mean age: 46.9 years, SD = 16.03). Log-link binomial regression analyses were performed to examine associations between four measures of ACEs (family conflict, lack of adult support, bad memories, and difficult childhood) and demographic (age, gender, civil status, parental divorce) and socioeconomic characteristics (education level, perceived financial situation, and welfare benefits). Results: Single individuals and those with parents that divorced during childhood were at elevated risk of all four ACEs. The risk varied to some degree between the sexes. The prevalence of ACEs declined with increasing age. We found a consistent social gradient that corresponded to the frequency of ACEs for all three socioeconomic characteristics investigated. The risks were highest for those in the lowest socioeconomic levels (RR: 1.53, 95% CI: 1.32-1.78 to RR: 4.95, CI: 4.27-5.74). Conclusions: Public health strategies should direct more attention to the interplay between ACEs and socioeconomic factors. Welfare services should be sensitive to ACEs among their service recipients.

Associations between adverse childhood experiences and adversities later in life. Survey data from a high-risk Norwegian sample.

BACKGROUND: A history of childhood abuse and neglect (CAN) is associated with exposure to later negative life events. CAN at an early age, multiple cooccurring exposures (cumulative events), and a high severity and frequency of exposure have potential detrimental long-term effects. OBJECTIVE: The present study examines the relationship between the severity of CAN and the prevalence of school difficulties and hardship at school, adult adversity and mental health. PARTICIPANTS AND SETTINGS: Participants were recruited from in- and outpatient mental health or substance abuse treatment facilities, child protective services (CPS), and prisons (N = 809, age range = 13-66, mean age = 27.62, SD = 10.47). METHODS: Exposure to childhood maltreatment was assessed by the Childhood Trauma Questionnaire Short Form (CTQ-SF). After adjusting for gender and age, we conducted a risk ratio regression analysis to investigate associations between severity of child abuse and neglect and hardship at school, adult adversity and adult mental health. RESULTS: The moderate and severe level groups of CAN had statistically significant higher risk ratios for experiences of school difficulties, hardship at school, adult adversity and mental health problems. A robust dose-response was found between severity levels. CONCLUSION: At an individual level the findings highlight the association between exposure to abuse and adult adversity, underscoring the importance of targeting individuals with high risk of exposure to CAN to reduce the negative long-term risk for Polyvictimization.

Childhood maltreatment trauma: a comparison between patients in treatment for substance use disorders and patients in mental health treatment.

Background: While previous research has found strong associations between childhood maltreatment trauma and substance use disorders (SUDs), the role of possible moderating effects of gender and mediating effects of psychopathology and SUD is unclear. Objective: The objective of this study was to investigate differences in self-reported childhood maltreatment trauma, general psychological distress, and post-traumatic stress symptoms between 112 patients in treatment for substance use disorders (SUD group) and 112 matched controls with mild to moderate mental health disorders (comparison group). Methods: Childhood maltreatment trauma was measured by the Childhood Trauma Questionnaire - Short Form (CTQ-SF). General psychological distress was measured by the Symptom Checklist-90 - Revised (SCL-90-R), and post-traumatic stress symptoms were measured by the Impact of Event Scale - Revised (IES-R). Results: The SUD group reported more severe childhood maltreatment trauma than the comparison group. Females in the SUD group reported more severe and various forms of trauma compared to males. The SUD group reported higher mean scores on the SCL-90-R, but the proportions of people with caseness scores on the IES-R and the SCL-90-R were similar in the two samples. The SUD group reported more avoidance symptoms than the comparison group. Conclusion: This study adds further evidence to the repeatedly found strong associations between childhood maltreatment trauma and SUD, implying that the prevention of childhood maltreatment trauma may reduce the occurrence of SUD. Furthermore, patients with SUD should be screened for childhood maltreatment trauma, and the results should be applied in trauma-informed as well as trauma-focused interventions aimed to help this population. The association appears to be particularly strong for female substance users.

Antecedentes: Si bien investigaciones previas han encontrado fuertes asociaciones entre el trauma por maltrato infantil y los trastornos por uso de sustancias (SUD), no está claro el papel de los posibles efectos moderadores del género y los efectos mediadores de la psicopatología y el SUD.Objetivo: El objetivo de este estudio fue investigar las diferencias en el trauma de maltrato infantil autoreportado, el estrés psicológico general y los síntomas de estrés postraumático entre 112 pacientes en tratamiento por trastornos por consumo de sustancias (grupo SUD) y 112 controles emparejados con trastornos de salud mental leves a moderados (grupo de comparación).Métodos: el trauma por maltrato infantil se midió mediante el Cuestionario de Traumas de la Infancia, versión abreviada (CTQ-SF). El estrés psicológico general se midió mediante la Lista de Chequeo de Síntomas Revisada (SCL-90-R), y los síntomas de estrés postraumático se midieron mediante la Escala de Impacto de Eventos Revisada (IES-R).Resultados: El grupo SUD reportó trauma de maltrato infantil más severo que el grupo de comparación. Las mujeres en el grupo SUD reportaron formas más graves y diversas de trauma en comparación con los hombres. El grupo SUD informó puntuaciones medias más altas en el SCL-90-R, pero las proporciones de personas con puntajes de casos en el IES-R y el SCL-90-R fueron similares en las dos muestras. El grupo SUD informó más síntomas de evitación que el grupo de comparación.Conclusión: Este estudio agrega evidencia adicional a las fuertes asociaciones encontradas repetidamente entre el trauma por maltrato infantil y el SUD, lo que implica que la prevención del trauma de maltrato infantil puede reducir la ocurrencia de trastornos por uso de sustancias. Además, los pacientes con SUD deberían ser evaluados para detectar traumas por maltrato infantil y los resultados deberían aplicarse en intervenciones basadas en el trauma e intervenciones focalizadas en el trauma dirigidas a ayudar a esta población. La asociación parece ser particularmente fuerte para las mujeres usuarias de sustancias.

Childhood trauma in schizophrenia spectrum disorders as compared to substance abuse disorders.

The prevalence of childhood trauma (CT) in schizophrenia spectrum disorders (SSDs) and substance abuse disorders (SUDs) is high. Direct comparisons of CT in these disorders are lacking, and it is not known whether there are differences in self-reported CT in SSDs as compared to SUDs. We aimed to compare the frequency, severity and types of CT in SDDs and SUDs. Patients with SSDs (n = 57) and SUDs (n = 57) were matched for age and gender. Overall levels of CT and CT subtypes were measured retrospectively by the Childhood Trauma Questionnaire Short-Form (CTQ-SF), and grouped into none/low and moderate/severe levels of CT. Group differences in CTQ-SF sum score and subscale scores, as well as differences in the severity of overall CT and CT subtypes were all non-significant. In both groups, 64.9% reported ≥ 1 subtypes of CT above cut-off. Of those who reported CT above the cut-off, 13.5% in the psychosis group reported ≥ 4 subtypes, as compared to 2.7% in the substance abuse group. We did not find statistically significant differences between SSDs and SUDs in terms of exposure to CT frequency or severity, all effect sizes were small (r < 0.15).
