Abstract:
This study utilized a nonconcurrent case-series design to examine the effectiveness and acceptability of a guided self-help Acceptance and Commitment Therapy (ACT) intervention for people with psychogenic nonepileptic seizures. A key aim of the study was to investigate the relationship between psychological flexibility (a key process within ACT), psychological health, quality of life, and seizure frequency. Six participants completed the study, with reliable and clinically significant changes in psychological flexibility, quality of life, and psychological health observed in the majority of participants. Notable reductions in self-reported seizure frequency were also observed. The implications of these findings for clinical practice are discussed and recommendations for future research suggested.
