Dissocial behavior, the 5HTTLPR polymorphism, and maltreatment in women with bulimic syndromes
Bibliographic record
Abstract
We recently reported that, among bulimic women, previously abused carriers of the 5HTTLPR S allele showed special propensities towards novelty seeking (implying recklessness or impulsivity) and interpersonal insecurity. We subsequently re-analyzed our data, to examine the bearing of the 5HTTLPR polymorphism and prior sexual or physical maltreatment upon validated, higher-order personality-traits. Ninety women with bulimic syndromes were genotyped for 5HTTLPR "short" (S) and "long" (L(G) and L(A)) alleles, and then assessed for eating symptoms, history of sexual or physical abuse, and the higher-order personality traits Emotional Dysregulation, Dissocial Behavior, Inhibition, and Compulsivity. With a classification based on a biallelic model of 5HTTLPR (i.e., presence or absence of at least one S-allele copy), multiple regression indicated a significant proportion of variance in Dissocial Behavior to be explained by an abuse x genotype interaction-greater psychopathology occurring in abused S-allele carriers. A parallel analysis applying a triallelic model of 5HTTLPR (i.e., presence or absence of at least one copy of presumably low-function S or L(G) alleles) produced a similar pattern, but no statistically significant effect. The finding that bulimic 5HTTLPR S-allele carriers who are previously abused display elevations on Dissocial Behavior corroborates previous observations concerning phenomenological correlates of traumatic stress in 5HTTLPR S allele carriers.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
