[Construction and validation of visual analogue scale for risk assessment].
This paper describes the factor structure and validity of a visual analogue scale designed to rate risk proneness: EVAR (EVAluation of Risk). Risk behaviors and sensation seeking are related, therefore we correlated EVAR (24 100 mm items) with Zuckerman Sensation Seeking Scale (SSS) (40 conventional items) in a population of 199 volunteers. Subjects had an age range of 18-68 years (mean age of 31), and 49 were females. Factor analysis using a principal component solution and an orthogonal rotation of the factor matrix were computed. Five factors were selected, accounting for 46 per cent of the total variation: F1 "self control", F2 "danger seeking", F3 "energy", F4 "impulsiveness", F5 "invincibility". F1, F2 and F3 from EVAR were correlated with SSS factors "general", "danger seeking", "experience seeking" and "boredom susceptibility". F4 was correlated with "general", "boredom susceptibility" and "disinhibition" whereas F5 was not correlated with any of SSS factors. This visual analogue scale is likely to reveal change in subjects, regarding risk proneness, when submitted to various stressors (sleep deprivation, fatigue...).
