Editorial: 'The early bird catches the worm'-the need for even earlier intervention and targeted prevention for mental illnesses

Does child abuse predict a population segment with large economic burden?

OBJECTIVES

The enormous societal and individual consequences of mental health disorders and detrimental health behaviours in the general population are of paramount concern. Many argue that 'prevention is the best cure', pushing for the implementation of early (preventive) interventions. Key questions regarding early interventions include which population segment to target for screenings and what information these screenings should focus on. In line with previous efforts, this study aimed to identify which population segment holds the majority (≥ 80 %) of different economically costly outcomes in society, and whether child abuse before the age of 16 years predicts being part of that population segment.

STUDY DESIGN

Epidemiological cohort study.

METHODS

This study used the Netherlands Mental Health Survey and Incidence Study-2, a Dutch epidemiological cohort study including 6646 adults aged 18-64 years at baseline, spanning four timepoints from 2007 to 2018. Cumulative distributions were computed to identify high-cost population segments of economically costly outcomes in adulthood (i.e., mental and physical health [behaviours], unemployment and work absenteeism). Child abuse was examined as a potential predictor of these segments and the risk of multiple high-cost population segment membership was investigated by conducting Poisson regressions.

RESULTS

A 20 % population segment carried between 42 % and 100 % of economically costly outcomes. Being exposed to more child abuse predicted being in a high-cost population segment, albeit with small effect sizes. Being exposed to more child abuse also predicted belonging to multiple high-cost population segments across different economically costly outcomes.

CONCLUSIONS

The study findings have implications for policy makers. Emphasis should be placed on prevention aimed at identifying potential members of multiple high-cost population segments.

Predicting comorbid mental health difficulties in people with autoimmune arthritis

Little is known about variables impacting the association between mental health difficulties and autoimmune conditions. This study investigates whether, age of onset, adverse childhood experiences (ACEs), and 'illness invisibility' predict comorbid mental health difficulties in people with autoimmune arthritis. Participants with autoimmune arthritis (N = 209) were recruited via social media platforms. Age of onset of arthritis and the temporal order of mental health difficulties (if applicable) were collected alongside a measure of personality and ACEs. A novel measure of illness invisibility was developed for this study. A cross-sectional mixed-subject design was utilised. 53.5% of the sample endorsed lifetime mental health difficulties. Logistic regression analyses revealed participants with a younger age of onset of arthritis had significantly higher odds of developing a mental health problem (OR 0.93, 95% CI 0.90-0.96). Independently, Illness Invisibility, endorsed by 89.9% of participants, significantly predicted postmorbid mental health difficulties (OR 1.08, 95% CI 1.01-1.19). Adverse Childhood Experiences were frequently endorsed within the sample with 37.8% reporting ≥ 3 cumulative ACEs. Every unit increase in ACEs increased the odds of having comorbid mental health difficulties (OR 1.27, 95% CI 1.09-1.47). Young people who are diagnosed with autoimmune arthritis maybe more likely to experience subsequent mental health difficulties. The 'invisibility' of their illness and exposure to ACEs also is associated with their risk for mental health complications. These findings highlight the importance of mental health screening for young people being investigated for arthritis and interdisciplinary care, especially for young people.

Implementation outcomes in psychosocial intervention studies for children and adolescents living in low- and middle-income countries: A systematic review

Psychosocial interventions play a key role in addressing mental health and substance use needs for children and adolescents living in low- and middle-income countries (LMICs). While research efforts have primarily focused on their effectiveness, implementation outcomes also require examining. We conducted a systematic review of qualitative, quantitative, and mixed-methods studies (PROSPERO: CRD42022335997) to synthesize the literature on implementation outcomes for psychosocial interventions for children and adolescents in LMICs. We searched Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Web of Science, PsychINFO, and Global Health through April 2023. Data were extracted and quality appraised through the Mixed Methods Appraisal Tool (MMAT) independently by two reviewers. A total of 13,380 records were screened, and 87 studies met inclusion criteria. Feasibility was the most reported implementation outcome (69, 79%), followed by acceptability (60, 69%), and fidelity (32, 37%). Appropriateness was assessed in 11 studies (13%), implementation costs in 10 (11%), and sustainability in one (1%). None of the included studies reported on penetration or adoption. Despite a growing body of evidence for implementation research in child and adolescent global mental health, most research focused on earlier-stage implementation outcomes, assessing them in research-controlled settings. To overcome this, future efforts should focus on assessing interventions in routine care, assessing later-stage implementation outcomes through standardized tools.

Experiencing stress impact on adolescent repetitive nonsuicidal self-injury: The Mediating role of emotion dysregulation and maladaptive cognitive schemas

BACKGROUND

Repetitive nonsuicidal self-injury (R-NSSI) is a growing concern in adolescents and is associated with various mental health problems. However, little is known about the potential psychology and addiction mechanisms of R-NSSI in adolescents. This study aimed to examine the mediating effects of emotion dysregulation and maladaptive cognitive schemas based on the Interaction of Person-Affect-Cognition-Execution (I-PACE) model and the integrated model of NSSI among adolescents who repeatedly engage in NSSI.

METHODS

This longitudinal study was conducted in two waves with 6-month lags. A total of 3925 adolescents (Mage = 13.22 ± 0.86 years, 42 % female) were recruited from three middle schools. Relevant questionnaires were used to evaluate stressful life events, emotion dysregulation, maladaptive cognitive schemas, NSSI, and NSSI addictive features. The structural equation modeling approach was conducted separately for adolescents who engaged in occasional NSSI (O-NSSI) and those who engaged in R-NSSI.

RESULTS

Results showed that emotion dysregulation played a significant mediating role in the associations between stressful life events and NSSI frequency, and both maladaptive cognitive schemas and emotion dysregulation played a significant mediating role in the associations between stressful life events and NSSI addictive features in adolescents who engaged in R-NSSI but not in those who engaged in O-NSSI.

LIMITATIONS

The main limiting factor is self-reported data.

CONCLUSIONS

These findings contribute to the understanding of the psychological and addictive mechanisms involved in R-NSSI. Both emotion dysregulation and maladaptive cognitive schemas could be a suitable therapeutic target to reduce R-NSSI in the context of stress during adolescence.

Out-of-home care characteristics associated with childhood educational underachievement, mental disorder, and police contacts in an Australian population sample

BACKGROUND

Children in out-of-home care (OOHC) are generally at increased risk of health and social adversities compared to their peers. However, the experiences of children in OOHC are not uniform and their associated health and social indices may vary in relation to characteristics of OOHC placements and child protection contact.

OBJECTIVE

To examine associations between a range of characteristics of OOHC placements and child protection contact (e.g., number, type, and age of placement) with educational underachievement, mental disorder, and police contact (as a victim, witness, or person of interest) in childhood.

PARTICIPANTS AND SETTING

Participants were Australian children drawn from the New South Wales Child Development Study cohort who had been placed in OOHC at least once between the ages of 0-13 years (n = 2082).

METHODS

Logistic regression was used to examine prospective associations of OOHC placement and child protection contact characteristics (type of carer, placement instability, duration and frequency of maltreatment, and amount of time in care) with educational underachievement, mental disorder diagnosis and any type of police contact.

RESULTS

Placements with foster carers, greater placement instability, longer and more frequent exposure to maltreatment, and longer time spent in care were each associated with greater likelihood of consequences in all domains of functioning.

CONCLUSIONS

Children with certain placement characteristics are at higher risk of adverse consequences and should be prioritised for support services. The magnitude of relationships was not uniform across different health and social indices, highlighting the need for holistic, multiagency approaches to support children placed in care.

Cumulative Environmental Risk in Early Life: Associations With Schizotypy in Childhood

BACKGROUND AND HYPOTHESIS

Psychotic disorders are associated with a growing number of recognized environmental exposures. Cumulative exposure to multiple environmental risk factors in childhood may contribute to the development of different patterns of schizotypy evident in early life. Hypotheses were that distinct profiles of schizotypy would have differential associations with a cumulative score of environmental risk factors.

STUDY DESIGN

We prospectively examined the relationship between 19 environmental exposures (which had demonstrated replicated associations with psychosis) measured from the prenatal period through to age 11 years, and 3 profiles of schizotypy in children (mean age = 11.9 years, n = 20 599) that have been established in population data from the New South Wales-Child Development Study. Multinomial logistic regression was used to examine associations between membership in each of 3 schizotypy profiles (true schizotypy, introverted schizotypy, and affective schizotypy) and exposure to a range of 19 environmental risk factors for psychosis (both individually and summed as a cumulative environmental risk score [ERS]), relative to children showing no risk.

RESULTS

Almost all environmental factors were associated with at least 1 schizotypy profile. The cumulative ERS was most strongly associated with the true schizotypy profile (OR = 1.61, 95% CI = 1.52-1.70), followed by the affective (OR = 1.33, 95% CI = 1.28-1.38), and introverted (OR = 1.32, 95% CI = 1.28-1.37) schizotypy profiles.

CONCLUSIONS

Consistent with the cumulative risk hypothesis, results indicate that an increased number of risk exposures is associated with an increased likelihood of membership in the 3 schizotypy profiles identified in middle childhood, relative to children with no schizotypy profile.

Adverse childhood experiences and global mental health: avenues to reduce the burden of child and adolescent mental disorders

Mental disorders are one of the largest contributors to the burden of disease globally, this holds also for children and adolescents, especially in low- and middle-income countries. The prevalence and severity of these disorders are influenced by social determinants, including exposure to adversity. When occurring early in life, these latter events are referred to as adverse childhood experiences (ACEs).In this editorial, we provide an overview of the literature on the role of ACEs as social determinants of mental health through the lenses of global mental health. While the relation between ACEs and mental health has been extensively explored, most research was centred in higher income contexts. We argue that findings from the realm of global mental health should be integrated into that of ACEs, e.g. through preventative and responsive psychosocial interventions for children, adolescents and their caregivers. The field of global mental health should also undertake active efforts to better address ACEs in its initiatives, all with the goal of reducing the burden of mental disorders among children and adolescents globally.

Editorial: Prevention is the best cure

In this issue of Journal of Child Psychology and Psychiatry, many interesting research findings converge to suggest that prevention and early intervention strategies can be the key to building healthier societies with happier people. Across different societies, we observe that scientific attention and practice is becoming more evenly divided between the traditionally dominant focus on clinical disorders and residential treatments on the one hand and a burgeoning focus on prevention and resilience in ambulant settings and younger populations on the other hand.

Movement Behaviors and Mental Wellbeing: A Cross-Sectional Isotemporal Substitution Analysis of Canadian Adolescents

Background: Studies have shown reallocating screen time for healthy movement behaviors such as physical activity and sleep can provide important benefits for mental health. However, the focus on positive aspects of mental health such as wellbeing has received limited attention, particularly among adolescents. The purpose of this study was to examine the effects of reallocating physical activity, screen time, and sleep on mental wellbeing in adolescents.

Methods: This study involved cross-sectional analysis of data from Wave 1 of the ADAPT study. A total of 1,118 Canadian adolescents enrolled in grade 11 classes (M_AGE = 15.92; 54.5% female) self-reported their movement behaviors using the International Physical Activity Questionnaire – Short Form to assess moderate-to-vigorous physical activity and daily recall questionnaires to assess recreational screen time and sleep. Participants also completed three measures of mental wellbeing: the Flourishing Scale, Rosenberg Self-Esteem Scale, and a brief Resiliency scale from the Canadian Campus Wellbeing Survey.

Results: Isotemporal substitution analysis revealed replacing 60 min of screen time with either moderate-to-vigorous physical activity or sleep has significant benefits for mental wellbeing. Comparatively, reallocating 60 min between moderate-to-vigorous physical activity and sleep does not impact mental wellbeing.

Discussion: Findings suggest healthy movement behaviors confer similar beneficial effects for adolescent’s mental wellbeing. Health promotion campaigns targeted toward adolescents should consider highlighting that reallocation of screen time to either sleep or moderate-to-vigorous physical activity may provide important benefits for mental wellbeing.
