Abstract. Driving anxiety is a common experience that, for those with high levels of driving anxiety, can markedly interfere with functioning, particularly because of avoidance behavior. The Driving and Riding Avoidance Scale (DRAS; Stewart &amp; St. Peter, 2004 ) is a promising measure of self-reported avoidance, but its psychometric properties have been questioned as the instructions do not specifically ask respondents to report avoidance that is due to driving anxiety. The present study investigated the psychometric properties of the DRAS using revised instructions in 437 participants from the general population of New Zealand. Internal consistency for the DRAS was 0.94 and ranged from 0.79 to 0.90 for the four subscales. A two-factor solution was supported, in line with previous research using the revised instructions, supporting the distinction between general and traffic avoidance compared with weather and riding avoidance. Further work on the psychometric properties of this measure with clinical samples is needed to clarify the subscale structure.
