Özet
Background: Erectile dysfunction (ED) is a prevalent condition that affects quality of life and intimate relationships. Treatment satisfaction represents a broader patient-centered outcome than erectile function alone. The Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) assesses satisfaction from patient and partner perspectives. This study aimed to translate, culturally adapt, and evaluate the psychometric properties of the Turkish EDITS patient and partner forms in men using three-piece inflatable penile prostheses and their partners. Methods: This methodological study included 200 men with ED who had used a three-piece inflatable penile prosthesis for at least six months. Of these, 122 had partners who completed the partner questionnaire, yielding 122 complete patient–partner dyads. The patient and partner forms were translated using a forward–backward translation procedure. Internal consistency was evaluated using Cronbach’s alpha and ordinal alpha. Construct validity was examined using single-factor confirmatory factor analysis (CFA) with a robust weighted least squares mean- and variance-adjusted estimator. Patient–partner association was evaluated using Spearman’s rho in the 122 matched dyads. Results: Complete item-level data were available for all 200 patient questionnaires and 122 partner questionnaires. Cronbach’s alpha was 0.97 for the patient form and 0.65 for the partner form; ordinal alpha was 0.98 and 0.70, respectively. No floor or ceiling effect was observed. CFA supported the proposed one-factor structure at the global-fit level, although the boundary fit indices were interpreted cautiously. Standardized factor loadings ranged from 0.83 to 0.90 for the patient form and from 0.40 to 0.80 for the partner form. The partner form demonstrated comparatively weaker convergent validity (CR = 0.73; AVE = 0.41). Patient and partner total scores demonstrated a statistically significant moderate-to-strong positive association among the 122 matched dyads (Spearman’s ρ = 0.64, p < 0.001), which was interpreted as an association rather than agreement. Conclusion: The Turkish EDITS patient form demonstrated strong internal consistency and factorial validity in men using three-piece inflatable penile prostheses. The partner form showed preliminary and comparatively weaker psychometric performance, with marginal internal consistency and lower convergent-validity indicators. Further studies should examine test–retest reliability, responsiveness, external validity, and performance in broader ED treatment populations.
