Croft erroneously states that we assumed that claim closure is a proxy for recovery. In fact, as indicated in our article, we studied the validity of claim closure as an indicator of health recovery and reported a strong and independent relationship between the rate of recovery, as measured by self-reports of neck pain intensity, physical functioning and depressive symptomatology, and the rate of claim closure.1,2 The same issue has been raised previously and was answered in detail at the time.3 Croft also inaccurately states that we did not contact the claimants during follow-up. Claimants who consented were mailed follow-up questionnaires at approximately 6 weeks, 4 months, 8 months, and 12 months after collision.1,2 We invite Croft to review our study methodology, which we have described in detail.1,2
