The RoBIN-T scale for rating single case designs

Not all single-case designs have high methodological quality. The revised Risk of Bias in N of 1 Trials (RoBiN-T) scale can be used to:

• Identify experimental versus non-experimental single-case designs
  • Experimental designs are those which use variants of the withdrawal/reversal design (e.g. ABA), multiple baseline designs, alternating treatment designs and changing criterion designs.
  • Non-experimental designs include those that use a single phase or are bi-phasic only (eg. A-B), contain pre/post data only and case descriptions.
• Rate the methodological quality of experimental single-case designs.

The RoBIN-T scale is detailed in a recent publication: Tate, R.L, Perdices, M., Rosenkoetter, U., Wakin, D., Godbee, K., Togher, L. & McDonald, S. (2013) Neuropsych Rehab 23(5): 619-638. A manual is currently being developed.
