Dimensions of deprivation and threat, psychopathology, and potential mediators: A multi-year longitudinal analysis.

ABSTRACT: Prior research demonstrates a link between exposure to childhood adversity and psychopathology later in development. However, work on mechanisms linking adversity to psychopathology fails to account for specificity in these pathways across different types of adversity. Here, we test a conceptual model that distinguishes deprivation and threat as distinct forms of childhood adversity with different pathways to psychopathology. Deprivation involves an absence of inputs from the environment, such as cognitive and social stimulation, that influence psychopathology by altering cognitive development, such as verbal abilities. Threat includes experiences involving harm or threat of harm that increase risk for psychopathology through disruptions in social-emotional processing. We test the prediction that deprivation, but not threat, increases risk for psychopathology through altered verbal abilities. Data were drawn from the Child Development Project (N = 585), which followed children for over a decade. We analyze data from assessment points at age 5, 6, 14, and 17 years. Mothers completed interviews at age 5 and 6 on exposure to threat and deprivation experiences. Youth verbal abilities were assessed at age 14. At age 17, mothers reported on child psychopathology. A path analysis model tested longitudinal paths to internalizing and externalizing problems from experiences of deprivation and threat. Consistent with predictions, deprivation was associated with risk for externalizing problems via effects on verbal abilities at age 14. Threat was associated longitudinally with both internalizing and externalizing problems, but these effects were not mediated by verbal abilities. Results suggest that unique developmental mechanisms link different forms of adversity with psychopathology. (PsycINFO Database Record

Project description:BackgroundComorbidity between psychopathologies may be attributed to genetic and environmental differences between people as well as causal processes within individuals, where one pathology increases risk for another. Disentangling between-person (co)variance from within-person processes of psychopathology dimensions across childhood may shed light on developmental causes of comorbid mental health problems. Here, we aim to determine whether and to what extent directional relationships between psychopathology dimensions within-person, and between individuals within families, play a role in comorbidity.MethodsWe conducted random intercepts cross-lagged panel model (RI-CLPM) analyses to unravel the longitudinal co-occurrence of child psychopathology dimensions, jointly estimating between-person and within-person processes from childhood to early adolescence (age 7-12). We further developed an extension of the model to estimate sibling effects within-family (wf-RI-CLPM). Analyses were separately conducted in two large population-based cohorts, TEDS and NTR, including parent-rated measures of child problem behaviours based on the SDQ and CBCL scales respectively.ResultsWe found evidence for strong between-person effects underlying the positive intercorrelation between problem behaviours across time. Beyond these time-varying within-person processes accounted for an increasing amount of trait variance, within- and cross-trait, overtime in both cohorts. Lastly, by accommodating family level data, we found evidence for reciprocal directional influences within sib-pairs longitudinally.ConclusionsOur results indicate that within-person processes partly explain the co-occurrence of psychopathology dimensions across childhood, and within sib-pairs. Analyses provided substantive results on developmental processes underlying comorbidity in behavioural problems. Future studies should consider different developmental timeframes to shed more light on the processes contributing to developmental comorbidity.
