Lower levels of executive function have been associated with several domains of internalizing psychopathology. Executive function (EF) is a compilation of cognitive control processes, which enable self-regulation and goal-directed behaviors (Banich, 2009). Such processes play a fundamental role in an individual’s ability to make decisions, evaluate situations, and flexibly assimilate to novel life occurrences. Internalizing psychopathology is an umbrella term that refers to psychopathology syndromes with prominent dimensions of depression, worry, and fear (Banich et al., 2020). Research assessing adult psychopathology has found that adults with major depression and anxiety exhibit decreased levels of executive function in a multitude of behavioral areas. While all of these findings are important, it is not clearly understood if the research findings can be applied to adolescents. This study assesses whether either parent-reported or adolescent self-reported EF at an initial time point can predict subsequent symptoms of internalizing psychopathology, and whether that provides additional information above and beyond prior levels of psychopathology. We have taken a bifactor modeling approach in order to assess the common and unique aspects of internalizing psychopathology symptoms as they relate to adolescent EF (Banich et al., 2020). In addition to the latent variable factor scores, we also included the ASEBA (Achenbach System of Empirically Based Assessment) composite scores in our study as a clinical measurement of psychopathology. We concluded that adolescent self-reported BRIEF GEC scores can predict future common internalizing and low positive affect-specific psychopathology symptoms while accounting for baseline psychopathology.
