Individualized goal attainment scaling during a trial of positive behaviour support in adults with acquired brain injury.

BACKGROUND Challenging behaviours after acquired brain injury (ABI) cause distress and reduce community participation. Evidence-based and effective interventions are needed. Positive Behaviour Support (PBS) interventions, such as PBS + PLUS, are person-driven and context-sensitive approaches which aim to improve quality of life and enhance behavioural self-regulation. This study aimed to expand the empirical outcomes of a recent waitlist-controlled trial of PBS + PLUS by examining individualized goal attainment. METHOD Participants were 44 adults with severe ABI sustained on average nine years previously (Range = 0.6-26) from the combined trial cohort who completed the intervention. Using Goal Attainment Scaling, trial therapists developed and reviewed goals collaboratively with the person with ABI and their natural supports. RESULTS The 182 goals in the sample focussed on psychological wellbeing, interpersonal relationships, routines and self-care. By the end of 12-month intervention, 84.6% of goals were achieved and 53.3% exceeded their expected outcome. CONCLUSIONS These findings indicate high levels of personally meaningful outcomes in a broad range of life-domains can be obtained for participants with severe ABI using PBS + PLUS. Whilst these results should be considered in combination with the findings of the waitlist-controlled trial, they contribute to the growing literature regarding benefits of PBS in enhancing quality of life post-ABI.
