Development and validation of the arabic-modified erectile dysfunction inventory of treatment satisfaction (AM-EDITS) for assessing patient and partner satisfaction following malleable penile prosthesis implantation.

The Modified Erectile Dysfunction Inventory of Treatment Satisfaction is a validated English questionnaire designed to evaluate satisfaction after penile prosthesis implantation. However, no culturally adapted Arabic version currently exists. The objectives were to develop and validate the Arabic-Modified Erectile Dysfunction Inventory of Treatment Satisfaction for assessing patient and partner satisfaction following malleable penile prosthesis implantation. A prospective single-center validation study was conducted between August 2020 and July 2024. A total of 120 men with medication-refractory erectile dysfunction and their partners were enrolled. The Arabic-Modified Erectile Dysfunction Inventory of Treatment Satisfaction was created using a standardized forward-back translation and expert consensus process, followed by linguistic validation and pilot testing. Internal consistency and reliability were evaluated using Cronbach's α and the intraclass correlation coefficient. Participants completed structured telephone or online surveys at 1, 3, and 6 months postoperatively. Reduction of anxiety after preoperative counseling was evaluated through a direct binary response ("decreased" vs "unchanged"), while satisfaction domains were rated on 4-point Likert scales. The Arabic-Modified Erectile Dysfunction Inventory of Treatment Satisfaction demonstrated excellent psychometric properties (Cronbach's α = 0.979 for males; 0.951 for partners; intraclass correlation coefficient = 0.978 and 0.942, respectively). Preoperative counseling reduced anxiety in 82.5% of patients. At 1 month, 96.0% reported a "positive surgical experience" (defined as postoperative recovery being better or similar to expectations). At 3 months, 82.5% of patients were satisfied, 80.0% described erections as natural, and 92.5% of partners were satisfied (78.5% highly satisfied). By 6 months, patient satisfaction increased to 90.8%, whereas partner satisfaction declined to 84.2% (p < 0.001), suggesting emotional and psychosocial influences over time. Therefore, the Arabic-Modified Erectile Dysfunction Inventory of Treatment Satisfaction is a valid and reliable tool for evaluating satisfaction among Arabic-speaking patients and partners after malleable penile prosthesis. The findings highlight the importance of culturally sensitive counseling that involves both partners throughout the perioperative period.
