Abstract
Objectives
Accurate assessment of shared decision-making (SDM) is essential in emergency surgery, yet no culturally adapted and validated instrument is available in Iran. This study aimed to translate, culturally adapt, and assess the psychometric properties of the Persian SDM-Q-9 among patients undergoing emergency surgery.
Methods
This methodological cross-sectional study followed a forward-backward translation procedure to adapt the SDM-Q-9 into Persian. Face and content validity were established prior to construct validation. Data were collected from 575 patients undergoing emergency surgery and randomly split into two independent subsamples for exploratory factor analysis (EFA; n = 287) and confirmatory factor analysis (CFA; n = 288). Internal consistency was assessed using Cronbach's alpha, McDonald's omega, and composite reliability (CR). Convergent validity was examined using average variance extracted (AVE).
