a
Poor functioning (PSP) was a statistically significant univariate suitability indicator for Assertive Community Treatment, but PSP score was included in each of these models in step 2 (clinical characteristics) rather than step 4 as it was hypothesised to be a broad clinical predictor.
b
Single episode with good recovery; multiple episodes with good recovery; multiple episodes with partial recovery; continuous, chronic illness; continuous, chronic illness with deterioration.
c
Current case manager cannot be a predictor of entry to current service.
