MARTINEZ-SANCHEZ, José M.; CURTO, Ariadna  and  FERNANDEZ, Esteve. Agreement between two observers in the measurement of smoking and use of safety belt and cell phones in vehicles. Gac Sanit [online]. 2012, vol.26, n.1, pp.91-93. ISSN 0213-9111.

The aim of this study was to assess the feasibility of direct observations of smoking and use of seat belts and cell phones in drivers in the city of Barcelona, and to analyze the agreement between two observers. We performed 315 pairs of observations. The simple percentage inter-observer agreement between driver and passenger smoking was 100% with a Kappa coefficient=1.0. There was high inter-observer agreement in measurement of cell phone use and the number of passengers aged less than 14 years old. The variable with the lowest agreement was the driver's age. In conclusion, direct observation studies are a good resource for monitoring smoking and use of seat belts and cell phones in the drivers of motor vehicles.

Keywords : Observational studies; Agreement; Kappa coefficient.
