95. Is Brooding Rumination Specifically Depressogenic in Adolescents? Detangling Transdiagnostic and Disorder-Specific Pathways Using Latent Variable Modeling

Brooding rumination refers to the repetitive, passive focus on distress. Brooding is typically studied in the context of major depressive disorder (MDD). Some evidence, however, links rumination to diverse internalizing problems. Recent advances in quantitative psychopathology modeling (e.g., “HiTOP”; Kotov, 2017) provide a framework for examining whether risk factors predict specific disorders versus higher-order variance associated with transdiagnostic pathology. We use latent modeling to compare transdiagnostic versus diagnosis-specific pathways from brooding to psychopathology.

Adolescents (N=241) participated at baseline and 19-month follow-up. All data are collected. Supporting open science, analyses are being pre-registered. We will 1) factor analyze anxiety and depressive disorders at each time point to extract latent dimensions and 2) relate resulting transdiagnostic internalizing factors to brooding, examining brooding as a risk factor of later disorders. We hypothesize moderate, positive associations with the internalizing factor and weak associations with MDD-unique-pathology. If continuity prohibits longitudinal analyses, we will examine brooding as a cross-sectional correlate of internalizing pathology. In-progress pre-registration precludes presentation of results. However, previous analyses with this dataset suggest a unidimensional model of internalizing pathology offers acceptable fit (χ2(35)=57.78, p<.01; CFI=0.95; TLI=0.94; RMSEA=.05; WRMR=0.77) and estimates correlations with external outcomes. Findings will elucidate the transdiagnostic nature of brooding.
