Exploring the use of positive psychology interventions in brain injury survivors with challenging behaviour.

Objective: To investigate the feasibility and effectiveness of conducting two positive psychology interventions to improve mood and self-concept with survivors of traumatic brain injury (TBI), within a neuro-rehabilitation hospital. Method and procedures: Ten patients with brain injury were randomly allocated to an intervention and control group. The efficacy of the first intervention, `three positive things in life' was measured via Seligman's Authentic Happiness Index (AHI), at base-line, directly following the intervention and at the end of the 12-week group programme. The second intervention, the `Value in Action (VIA) signature strengths intervention' was measured by the Head Injury Semantic Differential Scale (HISDS) at baseline and at the end of the group. Results: Compared to baseline and control group scores, the AHI index showed an increase in the intervention group's happiness following the intervention and at the end of the 12-week programme, albeit the latter increase was non-significant. The HISDS showed non-significant improvement in self-concept and reduction in polarization of the self in the present, future and past in the second intervention. Anecdotal evidence revealed a clear improved mood following the interventions. Conclusion: This study shows promising results for the effectiveness of Positive Psychology interventions and methods to improve feasibility when applying this treatment within a hospital setting.
