Abstract
- Background Treatment expectations influence clinical outcomes in various physical and psychological conditions; however, no studies have explored their role in endometriosis treatment. It is necessary to understand how these expectations can be measured to study treatment expectations and their effects in clinical practice. This study aimed to psychometrically analyze and compare different treatment expectation measurements and describe treatment expectations in women with suspected endometriosis. Method Analysis of cross-sectional baseline data of a mixed-method clinical observational study of N=699 patients undergoing laparoscopy in Germany. Descriptives, bivariate associations, convergent and discriminant validity of four expectation measurements (Treatment Expectation Questionnaire (TEX-Q); Generic rating scale for previous treatment experiences, treatment expectations, and treatment effects (GEEE); numerical rating scales (NRS) assessing improvement and worsening of endometriosis symptoms, expected Pain Disability Index (PDI); range: 0 to 10) were estimated. A cluster analysis was performed on the three GEEE items. Results Most participants expected high improvement ( M=6.68 to 7.20, SD=1.90 to 2.09) and low worsening ( M=1.09 to 2.52, SD=1.80 to 2.25) of disability from laparoscopy. Participants who expected greater worsening expected more side effects ( r=.31 to .60, pr =|.24| to .00, p Conclusions Women with suspected endometriosis reported positive expectations concerning laparoscopy, but wide ranges indicated interindividual differences. Treatment expectations seem to be a multidimensional construct in this patient group. The investigated measurements did not correlate to the extent that they measured exactly the same construct. The selection of measurements should be carefully considered and adapted for the study purposes. Clusters provide initial indications for individualized interventions that target expectation manipulation. Trial Registration Number ID NCT05019612 ( ClinicalTrials.gov)

- Revised Amendments from Version 1 In the revised manuscript, we incorporated additional information, references, and statistics, and revised phrases based on the reviewer’s comments. The study aims were restructured for clarity and consistency. The first aim now focuses on describing treatment expectations (including cluster analysis), while the second aim compares expectation measures (including convergent and discriminant validity). The introduction was supplemented by a sentence and references to describe the association between depression, pain catastrophizing and anxiety with persistent complaints after laparoscopy. We clarified that only pre-operative variables were considered. Where appropriate, the terms “people” and “participants” were used instead of “women” (also in the title) since some individuals identified themselves as non-binary. The methods section now includes a table describing and comparing the four treatment expectation measures. Additionally, the following clinical data were added to the manuscript to describe the sample more thoroughly: self-reported duration of symptoms, previous experience with laparoscopy, current endocrine therapy, and whether complaints are dependent on menstrual bleeding. Although the manuscript's primary focus is methodological, we acknowledged the readers’ interest in clinical implications by adding discussion points of what is known to shape expectations for other patient groups and recommendations for future studies (i.e., longitudinal studies to explore whether more positive expectations lead to better treatment outcomes or disappointment due to overly optimistic expectations or whether expectations do not have an impact on post-operative outcomes; qualitative interviews to deepen understanding of expectations in endometriosis patients more deeply). Finally, the abstract was revised to align with these changes, reflecting the restructured aims, corresponding results, and conclusions., , [version 2; peer review: 2 approved with reservations]
