To determine content validity, the Delphi technique (3 rounds) with participating of 8 quality experts was used. Construct validity of the tool was assessed through exploratory and confirmatory factor analysis. Reliability was assessed using Cronbach's alpha coefficient. Data were analyzed by Excel, Spss, and Lisrel softwares.
Results: The content validity of tool with CVI=0.94 was confirmed. According to exploratory factor analysis, the hospital outpatient service quality tool included 36 items and 11 dimensions (choosing the service provider, communication and interaction, having authority, continuity of service, quality of facilities and basic amenities, respect, immediate and timely attention, safety, prevention, access and reliability). Construct validity of the tool was confirmed based on the goodness of fit quantities of model (RMSEA=0.007, CFI= 0.99, GFI=0.95).

Conclusion: The results of study showed that the outpatient SERVQUAL tool with 36 items and 11 dimensions was a valid and reliable tool to measure quality of outpatient service in Iranian hospitals.
