Abstract

Background: Recent research indicates that the best-fitting structural model of psychopathology includes a general factor capturing co-morbidity (p) and several more specific, orthogonal factors. Little is known about the stability of these factors, though two opposing developmental processes have been proposed: dynamic mutualism suggests that symptom-level interaction and reinforcement may lead to a strengthening of co-morbidity (p) over time, whereas p-differentiation suggests a general vulnerability to psychopathology that gives way to increasingly distinct patterns of symptoms over time. In order to test both processes, we examine two forms of developmental stability from ages 2-14 years: strength (i.e. consistency in the amount of variance explained by general and specific factors) and phenotypic stability (i.e. homotypic and heterotypic continuity). Methods: Data are from the NICHD Study of Early Child Care and Youth Development. Psychopathology symptoms were assessed 8 times between ages 2 and 14 years (n=1,253) using the Child Behavior Checklist completed by mothers. Confirmatory bifactor modelling was used to test structural models of psychopathology at each age. Consistency in strength was examined by calculating the Explained Common Variance (ECV) and phenotypic stability was investigated with cross-lagged modelling of the general and specific factors. Results: Bifactor models fit the data well across this developmental period. ECV values were reasonably consistent across development, with the general factor accounting for the majority of shared variance (61-71%). Evidence of both homotypic and heterotypic continuity emerged, with most heterotypic continuity involving the general factor, as it both predicted and was predicted by specific factors. Conclusions: A bifactor model effectively captures psychopathological comorbidity from early childhood through adolescence. The longitudinal associations between the general and specific factors provide evidence for both the hypothesized processes (dynamic mutualism and p-differentiation) occurring through development.
