Using proven measures of psychological, functional and independence assessment, such as FIM+FAM, SASNOS and OAS-MNR, we tracked key aspects of behaviour, alongside functional and cognitive change (such as personal hygiene and daily living management) for 11 patients who were admitted to Tallis and progressed through our ABI pathway for between 9 and 12  months.  Patients had been referred from other providers where aggression had previously escalated or where patients had failed to engage in therapeutic programmes and the placement subsequently broke down.
