Substance misuse over the first 18 months of specialized intervention for first episode psychosis
Bibliographic record
Abstract
AIM: Examine substance misuse over the first 18 months of first-episode psychosis treatment. METHOD: Clinicians rated alcohol and drug (mostly cannabis) misuse for 243 individuals followed prospectively. Assessments were completed at baseline and after 3, 6 and 18 months. Interventions relating to substance misuse included ongoing assessment of use, education and counselling to avoid. RESULTS: Alcohol and drug misuse declined significantly between baseline and 3 months, especially among patients with a substance abuse or dependence diagnosis at baseline. Overall, these reductions were maintained over the 18-month follow-up period. The exception was worsening alcohol misuse over time among patients with alcohol abuse or dependence on entry. CONCLUSIONS: With good usual care, education and support, alcohol and drug misuse declined significantly during the first months of psychosis treatment. The improvements in drug misuse were generally maintained over the 18-month follow-up, and worsening alcohol misuse over time may be the greater issue.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
