The establishment of predictive validity and the calculation of sensitivity and specificity were described for the DIAL-R. These results were compared with the concurrent and predictive validity figures from other screening tests. Suggestions for avoiding common problems include obtaining optimal cut-off scores by using the contrasting group method or by developing local norms and calculating sensitivity and specificity on one's own population and adjusting the cut-off points until the “best fit” is obtained.
