DBMAS, Dementia Behaviour Management Advisory Service; SBRT, Severe Behaviour Response Teams; MPC, mean percent change; d, Cohen's effect size.

$MPC=\frac{MCS}{MeanIntakeScore}$, where Mean Change Score (MCS) = Mean Intake Score−Mean Discharge Score.

No model adjustment used.

For the DBMAS program, the total NPI score is calculated as the sum of the 12 domain severity scores, and for the SBRT program the total score is calculated as the sum of the frequency multiplied by severity scores for each domain (0–144). The total distress score for both the NPI-Q and NPI-NH is calculated as the sum of the distress scores for each domain.

Negative signs preceding values represent improvement in scores.
