The aim of this study was to examine joint symptom trajectories, temporal precedence, risk factors, and population attributable fractions (PAFs) in a community sample of adolescents, using a developmental psychopathology and psychosocial framework.<\/jats:p><\/jats:sec><jats:sec id=\"S0954579423000792_as2\"><jats:title>Methods:<\/jats:title><jats:p>Across five years (age 14\u201318 years), adolescents (<jats:italic>n<\/jats:italic> = 544, 56% girls) reported on BPD features and disordered eating behavior. Sociodemographic, interpersonal, and clinical risks were assessed in childhood (age 10\u201313 years).

High levels of disordered eating were a stronger indicator of high levels of BPD features than was the reverse. Girls and LGBTQ+ youth were most likely to be in a high symptom trajectory. Bullying perpetration and clinical hyperactivity were unique risks for BPD features. Bullying victimization contributed the largest PAF to disordered eating and BPD features.<\/jats:p><\/jats:sec><jats:sec id=\"S0954579423000792_as4\"><jats:title>Conclusion:<\/jats:title><jats:p>We
