Abstract
Background: Research has linked individual differences in resting state functional connectivity (RSFC) of subcortical brain regions to internalizing disorders, but little research has examined if these changes are pre-morbid risk factors. This study examined individual differences in subcortical RSFC as risk factors for the first lifetime onset of an internalizing disorder in youth at familial risk. Methods: Participants (n = 93) were adolescents with a parental history of internalizing disorders, but with no such history themselves. Youth completed resting state fMRI scans, as well as the MINI-Kid and the Youth Self Report internalizing symptoms scale at baseline. The MINI-Kid was completed again at 9 or 18-month follow-up to assess onset of internalizing disorders. Seed-to-whole brain analyses consisted of a multiple regression models controlling for sex, age, in scanner motion, and baseline symptoms. Results: First onsets at follow-up were associated with increased baseline RSFC between the left caudate and the bilateral SMA (pFDR = .002), and between the right nucleus accumbens and the right superior parietal lobule (pFDR = .0003). Conclusion: Altered RSFC of subcortical regions may represent a pre-morbid risk factor for developing a first onset of an internalizing disorder. Results may have implications for understanding the neural bases of internalizing disorders and for early identification and prevention efforts.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
