Deterioration of mild anxiety and depression with Better Access treatment: implications for scaling up psychotherapy worldwide
Bibliographic record
Abstract
The Australian Medicare Better Access initiative in mental health reached one in every 10 Australians in 2021 (more than 2.6 million people) with interventions targeted at mild-to-moderate anxiety and depression, provided by general practitioners, allied health professionals, and/or psychiatrists, at a cost of AUD1.2 billion. However, the overall mental health of the Australian population has not improved since the introduction of Better Access. The benefits of population-scale mental health interventions (medications and psychotherapies) might have been overestimated for milder conditions, and the iatrogenic potential underestimated. A recent evaluation of Better Access found that mild anxiety and depressive symptoms were threefold more likely to worsen (32%) rather than improve (10%). Better Access might be targeted more cost-effectively towards severe and complex conditions, for which treatment appears to have superior risk-benefit ratios. These findings have implications for similar initiatives worldwide, such as those proposed by the World Health Organization.

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.
