Abstract

Introduction and hypothesis: We sought to further develop and validate the Surgical Preparedness Assessment (SPA) scale to evaluate patient preparedness for urogynecological surgery. Methods: This was a planned ancillary analysis of a randomized controlled trial (RCT) evaluating the impact of a preoperative telehealth call on patient preparedness for urogynecological surgery. Patients completed the Preoperative Preparedness Questionnaire (PPQ), the modified Preparedness for Colorectal Cancer Surgery Questionnaire (PCSQ), the Pelvic Floor Distress Inventory (PFDI-20), the Satisfaction Decision Scale (SDS), and the Decision Regret Scale (DRS). Content validity was established through expert opinion and patient cognitive interviews. Factor analysis identified item grouping into domains. Cronbach’s alpha reported internal consistency. Known group validity was assessed by comparing intervention arms. External validity was evaluated by comparing intervention arms and correlations with SDS and DRS. Results: Eleven items and 3 domains met the criteria (information needs, satisfaction and pain, and catheterization). Cronbach’s alpha values were acceptable for domains and ranged from 0.74 to 0.93. SPA scores did not correlate with other patient-reported outcomes. Mean SPA scores were lower among women who received a telehealth call vs those who did not (1.30 ± 0.31 vs 1.51 ± 0.44; p = 0.002). Conclusions: The content-valid SPA demonstrates high internal consistency and known group validity.
