Table 3.

The expected prevalence of MDQ positivity according to items 4 and 5 when adding to the first three item positive response at different cut off value

Cut-offa	Item-4 (+) Expected prevalenceb	Item-5 (+) Expected prevalenceb	Both Item 4 and 5 (+) Expected prevalenceb
5	2.0	3.2	0.9
6	1.6	2.6	0.3
7	1.9	3.0	0.4
8	1.5	1.5	0.5
9	1.9	1.9	0.6

^aThe frequency according to different cut-off scores were found from positive responses to first three items of MDQ plus item 4, item 5, and both item 4 and item 5. ^bExpected prevalence % was calculated according to sensitivity values reported in (Konuk et al., 2007)
