title: Development and validation of the Occupational Therapy Risk Propensity Test (OT-RiPT) for drivers with disability.
abstract: BACKGROUND
  Male drivers in the 16- to 19-year age group have a nine-fold increase in their crash risk compared with 25- to 34-year-olds who have a relative risk of 2.3. Crash risk in young drivers has been directly linked to risk-taking behaviour. This paper reports the development of a video risk assessment tool for use with drivers.
  
  
  OBJECTIVE
  This paper reports on the process of validating and investigating the reliability of the Occupational Therapy Risk Propensity Test (OT-RiPT) to measure risk-taking propensity.
  
  
  METHODS
  20 healthy male participants were recruited. OT-RiPT scores were correlated with driving experience. Internal consistency was investigated using Cronbach's alpha. Face validity was established. The OT-RiPT and a validated driver behaviour questionnaire were administered and the results correlated to establish discriminant validity.
  
  
  RESULTS
  There was no significant correlation between driving experience and OT-RiPT scores. Good internal consistency was established. OT-RiPT has high face validity. Discriminant validity was demonstrated.
  
  
  CONCLUSIONS
  Pending further testing, OT-RiPT shows promise as a reliable and valid measure of risk-taking propensity in young drivers.
