Abstract

fetched live from OpenAlex

OBJECTIVE: This pilot study compared the effectiveness of specialized care that was home based versus hospital based for individuals experiencing their first psychotic episode. METHOD: A randomized controlled trial design was used. A total of 29 subjects were interviewed at baseline, 3 and 9 months. Repeated measures analysis of variance was employed to test for statistically significant changes over time within and between groups with regard to community psychosocial functioning and symptom severity. RESULTS: Our findings indicate that subjects in both the home-based and hospital-based programmes significantly improved with regard to symptoms and community functioning over time. However, the rates of change over time were not significantly different between the two programmes. There was a statistically significant difference between programmes with regard to the proportion of subjects with less than two visits (i.e. either did not attend their first assessment or attended follow-up visits after their assessment). CONCLUSIONS: This was a modest pilot study and the sample was too small to allow definitive conclusions to be drawn. However, the results raise questions about differences in initial treatment engagement. They suggest the need for additional research focusing on interventions that promote initial treatment seeking.

Not 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.
