Positive PsychoTherapy in Acquired Brain Injury (ABI) Rehabilitation (PoPsTAR)

Stroke, head injury and other forms of brain injury are a major cause of physical, psychological and social disability in the adult population. Psychological distress is common following brain injury, but the evidence base for specific psychotherapeutic methods in this population is limited, and standard treatment approaches may not be suitable. Recently there has been a growing interest in positive psychology - the study of wellbeing, positive emotions and characteristics, and personal growth. The investigators believe that positive psychotherapy interventions may be beneficial after acquired brain injury, to reduce psychological morbidity. Because such interventions have not previously been applied in this population, the investigators propose to conduct a pilot randomised controlled trial to examine the feasibility of a brief positive psychotherapy intervention in an out-patient setting. This project will produce essential information to allow us to plan future full-scale clinical trials in this area.

Standard NHS care for the patient group (NHS care will vary as participants will be recruited from a variety of NHS clinics).
