Evaluating cutpoints for the MHI-5 and MCS using the GHQ-12: a comparison of five different methods Export

@article{citeulike:6055936, abstract = {BACKGROUND:The Mental Health Inventory (MHI-5) and the Mental Health Component Summary score (MCS) derived from the Short Form 36 (SF-36) instrument are well validated and reliable scales. A drawback of their construction is that neither has a clinically validated cutpoint to define a case of common mental disorder (CMD). This paper aims to produce cutpoints for the MHI-5 and MCS by comparison with the General Health Questionnaire (GHQ-12).METHODS:Data were analysed from wave 9 of the British Household Panel Survey (2000), providing a sample size of 14,669 individuals. Receiver Operating Characteristic (ROC) curves were used to compare the scales and define cutpoints for the MHI-5 and MCS, using the following optimisation criteria: the Youden Index, the point closest to (0,1) on the ROC curve, minimising the misclassification rate, the minimax method, and prevalence matching.RESULTS:For the MHI-5, the Youden Index and the (0,1) methods both gave a cutpoint of 76, minimising the misclassification rate gave a cutpoint of 60 and the minimax method and prevalence matching gave a cutpoint of 68. For the MCS, the Youden Index and the (0,1) methods gave cutpoints of 51.7 and 52.1 respectively, minimising the error rate gave a cutpoint of 44.8 and both the minimax method and prevalence matching gave a cutpoint of 48.9. The correlation between the MHI-5 and the MCS was 0.88.CONCLUSION:The Youden Index and (0,1) methods are most suitable for determining a cutpoint for the MHI-5, since they are least dependent on population prevalence. The choice of method is dependent on the intended application. The MHI-5 performs remarkably well against the longer MCS.}, author = {Kelly, Mark and Dunstan, Frank and Lloyd, Keith and Fone, David}, citeulike-article-id = {6055936}, citeulike-linkout-0 = {http://dx.doi.org/10.1186/1471-244X-8-10}, citeulike-linkout-1 = {http://view.ncbi.nlm.nih.gov/pubmed/18284689}, citeulike-linkout-2 = {http://www.hubmed.org/display.cgi?uids=18284689}, doi = {10.1186/1471-244X-8-10}, issn = {1471-244X}, journal = {BMC Psychiatry}, keywords = {depression, mcs, roc, sensitivity, sf-36, specificity}, number = {1}, pages = {10+}, posted-at = {2009-11-02 11:20:49}, priority = {2}, title = {Evaluating cutpoints for the MHI-5 and MCS using the GHQ-12: a comparison of five different methods}, url = {http://dx.doi.org/10.1186/1471-244X-8-10}, volume = {8}, year = {2008} }
