Coleman E, Smith J, Frank, J, et.al. Development and Testing of a Measure Designed to Assess the Quality of Care Transitions. International Journal of Care Integration.2002;2. http://www.caretransitions.org/documents/Dev%20and%20Testing%20-%20IJIC.pdf . Accessed August 1, 2014. Results: Older patients and clinicians found the measure to be highly relevant and comprehensive (i.e. content validity). Construct validity was assessed by comparing items from the CTM to selected items from a measure developed by Hendriks and colleagues (Medical Care 2001; 39(3): 270–283). Inter-item Spearman correlations ranged 0.388–0.594. No significant floor or ceiling effects were detected. Conclusions: The CTM was developed with substantial input from older patients and their caregivers. Psychometric testing suggested that the measure was valid. The CTM may serve to fill an important gap in health system performance evaluation by measuring the quality of care delivered across settings.
