A treatment cohort linked childhood physical neglect with poorer selected executive outcomes, greater craving and more positive urine results. It did not show that every type of childhood trauma predicted every outcome or that trauma determined an individual’s future.
The study followed 115 adults with methamphetamine use disorder in an outpatient program. Childhood experiences were assessed with a standardized retrospective questionnaire. Card sorting, dependence severity, craving and urine methamphetamine/amphetamine tests were assessed during a one-year program. Sixty-four participants completed treatment, making attrition important to interpreting later observations.
Physical-neglect history was associated with fewer completed card-sorting categories and poorer conceptual-level responses, more craving and a greater likelihood of positive urine results. Sexual-abuse history showed an association with dependence severity. These are distinct exposure categories and endpoints, not one uniform trauma score causing all impairment. The repeated assessments add information about treatment-course associations without making childhood exposure experimentally assigned.
Retrospective trauma reports can be affected by recall, and psychiatric comorbidity and other patient differences may contribute to outcomes. Treatment completion was only 55.7%, so later measurements should not be represented as complete follow-up of the original cohort. Positive urine results are chemical evidence under the assay’s reporting conditions, not a measure of cognitive impairment or precise use frequency. The findings support considering developmental history in treatment assessment while avoiding a deterministic judgment about relapse, capacity or character. They do not establish that methamphetamine alone caused the executive differences.
