Development and Psychometric Evaluation of Data-collection tools for Road Traffic Injury
چکیده
Introduction: Road Traffic Injuries (RTIs) impose a worldwide burden on
public health and economy. Moreover, RTIs result in a wide range of immediate
and long-term consequences. Comprehensive and accurate data is fundamentally
needed for effective management of RTIs. Hence, using reliable and valid data
collection tools are required. The present study is a part of national project of
Iranian Integrated Road Traffic Injury Registry (IRTIR).
Objectives: The objectives of the present study can be defined at two phases: 1-
Development and psychometric evaluation of data collection tool for inpatient road
traffic injuries; 2- Development and psychometric evaluation of data collection tool
for post-discharge consequences of road traffic injuries.
Methods: Data collection tools were developed by information retrieved from
literature review, needs assessment of experts and discussion in expert panel. The
content validity of the phase one data collection tool was assessed through an
external panel of experts. The phase two registry timeframe was designed at three
time-points based on literature review and expert’s opinion. The reliability of the
tools were evaluated using test-retest method and assessing interclass Correlation
Coefficient (ICC), modified Kappa, Kendall Tau and Cronbach’s alpha.
Results: The data collection tool for inpatient phase consisted of 53 items divided
into five categories. The content validity and stability of phase one data collection
tool was approved. The CVR for all items was ≥ 0.86 and ICC was ≥0.5. The triple
post-discharge consequences RTI data collection tools register data on
demographic, medical, psychiatric, economic and social characteristics.
Discussion: The inpatient data collection tool and post-discharge consequences
data collection tools were confirmed to be valid and reliable tools and suitable to be
used in the Iranian Integrated Road Traffic Injury Registry and similar settings.
