- Modified ride-on cars (ROCs) offer children with disabilities access to independent mobility. Aims: 1) To examine the association between caregiver attitudes towards self-directed mobility, caregiver alignment with the medical and social models of disability, and total modified ROC driving time; 2) To compare caregiver attitudes towards self-directed mobility, caregiver alignment with the medical and social models of disability, and total modified ROC drive times between high and low-use groups. Method: Fourteen children used a modified ROC during a 3 month intervention. At the end of the intervention, total car use was compared with primary caregiver disability model orientation and attitudes towards self-directed mobility. Results: Neither caregiver disability model orientation nor attitudes towards self-directed mobility were significantly associated with drive time. When comparing high and low use groups, total drive times and medical model alignment were significantly different. Caregivers in the high use group showed stronger alignment to the medical model (p<0.05). Conclusions: Evidence suggests that caregiver disability model orientation may influence provision of opportunities for their child to use a modified ROC. Further research is warranted to deepen our understanding of this relationship and explore other attitudinal measures which may facilitate or discourage modified ride-on car use in the real world.
