Zusammenfassung
Professional drivers are a group susceptible to sleep problems or incorrect rest patterns resulting from work stress that causes alterations in biological stress markers, such as cortisol, or in cardiovascular parameters that show a state of physiological hyper-activation. The current research objective was to adapt and validate the Groningen Sleep Scale (Meijman et al., 1990) in a Spanish population. We analysed its internal structure, reliability and evidence of validity. The participants in this study were 372 drivers (93.4% men, 6.6% women), with a mean age of 40.9 (SD = 10.54), obtained through non-probabilistic sampling. The SPSS 23.0 and AMOS (5.0) programs were used. With the confirmatory factor analysis (CFA) of the AMOS program (5.0), the indicators NFI = 0.902; TLI = 0.844; CFI = 0.913; RMSEA = 0.129 were obtained and showed an acceptable adjustment of the unifactorial model with 8 items. Adequate reliability (0.90) and appropriate evidence of validity with TDS-38, MBI-GS, Irritation, MP-9, DII, and Trans-18. We can conclude that the Groningen Sleep Scale (GSQS-8) is a reliable and valid instrument, suitable in the Spanish language for evaluating the sleep quality of professional drivers.
