Development and psychometric evaluation of data collection tools for Iranian integrated road traffic injury registry: Registrar-station data collection tool

Background: Comprehensive and accurate data are fundamentally needed for effective management of road traffic injuries (RTIs). Existing sources of RTI reports have a huge underestimation and inaccuracy at some levels. The aim of this study was to develop and validate the registrar-station data collection tool as a part of the Iranian Integrated Road Traffic Injury Registry (IRTIR). Materials and Methods: This study was conducted in Tabriz University of Medical Sciences in 2018. A data collection tool was developed to be used by the registrar for inpatient section of IRTIR by information retrieved from the literature review and road traffic experts' need assessment. The content validity of the preliminary tool was assessed. The feasibility of the tool was tested in two regional referral injury hospitals. Intra- and inter-rater reliability of the tool was evaluated using the individual/absolute intra-class correlation coefficient (ICC) and Kappa. Validity was revisited after 1 year of the pilot study. Results: The registrar-station data collection tool of IRTIR included 53 items, in five categories. Content validity was approved (modified content validity index was 0.8-1 and content validity ratio was one for all items). ICC was >0.6 for all items, and kappa index ranged between 0.69 and 0.92. The nurse data collection tool of IRTIR was applicable in the pilot phase. Conclusions: The Registrar-Station data collection tool of IRTIR was confirmed as a valid and reliable tool for inpatient traffic injuries as a part of the Iranian IRTIR
