Table 2.

The expected prevalence of MDQ positivity according to different cut off value of item 1 and positive response to items 2 and 3

Cut-off	Frequency	Percent (%)a	Expected prevalence %b
5	46	10.6	13.1
6	39	9.0	12.0
7	33	7.6	11.9
8	27	6.3	13.4
9	16	3.7	10.3

^aThe frequency according to different cut-off scores were found from positive responses to item 1 + item 2 + item 3

^bExpected prevalence % was calculated according to sensitivity values reported in (Konuk et al., 2007)
