Resum:
Background Professional drivers are susceptible to stress, which places both their own health and road safety at risk. For this reason the present study aims to create a short Spanish scale from the 59 items on the Bus Driver Risk Index (BDRI; Dorn, Stephen, af Wåhlberg, & Gandolfi, 2010), and to analyse its internal structure, reliability and evidence of validity. Method The participants were 372 Spanish drivers (93.4% male, 6.6% female), obtained by non-probabilistic sampling. The programs SPSS 20.0 and AMOS (5.0) were used. Results The Trans Driver Stress scale (TDS-15) provides a five-factor solution with 15 items, adequate reliability and appropriate evidence of validity. Through a confirmatory factor analysis, the following indicators (NFI = 90, TLI = .92; CFI = .91; RMSEA = .06) were obtained from the AMOS program (5.0) indicating that the five factor model has an acceptable fit. Evidences of validity are also proved with: SSQ-15, MBI-GS, Irritation, MP-9, DII and Trans-18. Conclusions The Trans Driver Stress scale (TDS-15) is a reliable and valid instrument, suitable for use in Spanish to evaluate the stress experienced by professional drivers in the transport industry.
