The Driving Attitudes and Self-Regulation Measure (Gwyther & Holland, 2012) was developed to assess drivers' attitudes and self-regulation behaviors. This measure was designed for a study of the effect of age, gender and attitudes on self-regulation in driving among a sample of drivers in the United Kingdom. The authors measured instrumental and affective attitudes and self-regulation behaviors using 18 items on a likert type scale from (1) ‘strongly disagree’ to (5) ‘strongly agree’. A list of questionnaire items and internal consistency (Cronbach’s alpha) for all three factors was provided. Items relating to instrumental and affective attitude were adapted and extended from an existing survey (Lindstrom-Forneri et al., 2007) reviewing driver attitudes and behaviour change in older adults (>60 years). Affective attitude questions were worded to derive a measure of negative affect. The self-regulation factor consisted of five items relating to commonly avoided difficult driving situations adapted from the Driving Habits Questionnaire (DHQ; Owsley et al., 1999)
