Contamination bias in the estimation of child maltreatment causal effects on adolescent internalizing and externalizing behavior problems
Background
When unaddressed, contamination in child maltreatment research, in which some proportion of children recruited for a nonmaltreated comparison group are exposed to maltreatment, downwardly biases the significance and magnitude of effect size estimates. This study extends previous contamination research by investigating how a dual-measurement strategy of detecting and controlling contamination impacts causal effect size estimates of child behavior problems.
Methods
This study included 634 children from the LONGSCAN study with 63 cases of confirmed child maltreatment after age 8 and 571 cases without confirmed child maltreatment. Confirmed child maltreatment and internalizing and externalizing behaviors were recorded every 2 years between ages 4 and 16. Contamination in the nonmaltreated comparison group was identified and controlled by either a prospective self-report assessment at ages 12, 14, and 16 or by a one-time retrospective self-report assessment at age 18. Synthetic control methods were used to establish causal effects and quantify the impact of contamination when it was not controlled, when it was controlled for by prospective self-reports, and when it was controlled for by retrospective self-reports.
Results
Rates of contamination ranged from 62% to 67%. Without controlling for contamination, causal effect size estimates for internalizing behaviors were not statistically significant. Causal effects only became statistically significant after controlling contamination identified from either prospective or retrospective reports and effect sizes increased by between 17% and 54%. Controlling contamination had a smaller impact on effect size increases for externalizing behaviors but did produce a statistically significant overall effect, relative to the model ignoring contamination, when prospective methods were used.
Conclusions
The presence of contamination in a nonmaltreated comparison group can underestimate the magnitude and statistical significance of causal effect size estimates, especially when investigating internalizing behavior problems. Addressing contamination can facilitate the replication of results across studies.
期刊介绍:
The Journal of Child Psychology and Psychiatry (JCPP) is a highly regarded international publication that focuses on the fields of child and adolescent psychology and psychiatry. It is recognized for publishing top-tier, clinically relevant research across various disciplines related to these areas. JCPP has a broad global readership and covers a diverse range of topics, including:
Epidemiology: Studies on the prevalence and distribution of mental health issues in children and adolescents.
Diagnosis: Research on the identification and classification of childhood disorders.
Treatments: Psychotherapeutic and psychopharmacological interventions for child and adolescent mental health.
Behavior and Cognition: Studies on the behavioral and cognitive aspects of childhood disorders.
Neuroscience and Neurobiology: Research on the neural and biological underpinnings of child mental health.
Genetics: Genetic factors contributing to the development of childhood disorders.
JCPP serves as a platform for integrating empirical research, clinical studies, and high-quality reviews from diverse perspectives, theoretical viewpoints, and disciplines. This interdisciplinary approach is a key feature of the journal, as it fosters a comprehensive understanding of child and adolescent mental health.
The Journal of Child Psychology and Psychiatry is published 12 times a year and is affiliated with the Association for Child and Adolescent Mental Health (ACAMH), which supports the journal's mission to advance knowledge and practice in the field of child and adolescent mental health.
