Statement of the Problem: Clinical studies in Epileptic Patients (EP) successfully treated with temporal lobectomy have
identified a range of psychosocial postoperative maladjustments. Such postoperative issues have also been reported in patients
treated with Deep Brain Stimulation (DBS). Researchers have suggested that pre-surgery unrealistic or unspecific expectations
may lead to adverse outcomes, despite significant improvements in objective measures. Although various assessments of
expectations have been used, there is no validated tool clearly focusing on expectations or hopes related to surgical treatment
for neurological diseases. The main purpose of this study was thus to develop an instrument assessing pre-surgery expectations/
hopes and to explore its psychometric properties across two clinical populations: Patients undergoing epilepsy surgery and
patients qualified for the DBS.
Methodology: The Treatment Hope and Expectations Questionnaire (THEQ) were elaborated following a thorough review of
relevant literatures. It consists in 22 statements exploring four expectations domains (daily living activities, mental and physical
health, psychological wellbeing, social-relational life). Each domain is assessed on 3 subscales: Realistic expectations, hopes
and current state (control measure). The THEQ was completed by 30 DBS and 30 EP before the planned surgery.
Findings: The THEQ had good psychometric properties. Paired t-tests conducted on realistic expectations and hope
total scores (i.e., cross-domains) revealed that both EP and DBS patients reported significantly higher hopes than realistic
expectations. Moreover, the two groups were characterized by high expectations and hopes for the mental and physical health
domain. Nevertheless, DBS patients had significantly higher expectations and hopes for the social-relational life domain as
compared to EP. By and large, DBS patients’ expectations and hopes were more attuned towards psychological or interpersonal
improvements as compared to EP.
Conclusion: DBS and EP endorsed different preoperative expectations, which may affect their adherence to treatment and
their postoperative satisfaction. Hence, the THEQ may help clinicians anticipating postoperative adjustment issues.

Michalina Radomska has completed her Master’s degree in Clinical and Cognitive Psychology from Faculty of Psychology and Educational Sciences at University
of Geneva, Switzerland. She is currently working as an Assistant and Clinical Psychologist in Psychopathology and Cognitive Neuropsychology Unit at University
of Geneva. She is also pursuing her PhD in Psychology in the field of psychological outcomes of deep brain stimulation for Parkinson’s disease. Her main research
interest lies in the understanding of the relationship between preoperative expectations and postoperative psychological adjustment in PD patients.
