Objective: The purpose of this study was to investigate personality and relationship patterns in patients with psychogenic non-epileptic seizures (PNES) and compare them to patients with epilepsy and healthy controls. Methods: A total of 68 participants were recruited (mean age = 29.8±9.4 years), including 25 (36.2%) with PNES. Assessment was conducted with Relationship Questionnaire (RQ), Big Five Inventory (BFI), Relationship Assessment Scale (RAS), Satisfaction with Life Scale (SWLS), and Conflict Behavior Scale (CBS). Results: The IQ of patients with PNES (88.8±13.6) was lower compared to healthy controls (103.5 ± 28.0) but higher than epilepsy patients (84.6±12.9). There were no significant differences between PNES patients and either patients with epilepsy or healthy controls on security, fearfulness, preoccupation, or dismissiveness based on RQ subscale scores. PNES patients tended to be less satisfied (RAS total score, p=0.10), but did not differ on overall life (on SWLS) compared to epilepsy patients and healthy. There were no significant differences in the scores for different attachment styles (Secure, Fearful, Preoccupied, Dismissing) among the groups (p>0.05). Significant differences were found in agreeableness (p=0.017) and openness (p=0.009) among the groups. PNES group exhibits higher scores in Negative-Own (p = 0.009), Positive-Own (p = 0.011), Negative-Partner (p = 0.011), and Positive-Partner (p = 0.028) compared to epilepsy and healthy. No significant differences observed in Abusive-Own and Abusive-Partner scores (p > 0.05). Conclusion: In conclusion, this study highlights distinct personality traits and relationship patterns in patients with psychogenic non-epileptic seizures (PNES) compared to epilepsy patients and healthy controls, emphasizing the need for targeted interventions to address these psychological nuances effectively.
