Corrections to PsyCourse Codebook version 4.1

1. In the dataset version 4.1, there is one control individual whose age is 8. This is a data entry mistake. The person is 23 years old. This will be corrected in the next version of the dataset.

2. The ordinal item "v1_scid_no_suic_attmpt" has only three levels: "1-one time", "2-two times", "3-three or more times". The current heading of the item description is thus wrong and should read "Number of suicide attempts (ordinal [1,2,3], v1_scid_no_suic_attmpt)". In the text of the item description, only the three levels should be mentioned.

In the original eCRF, the coding of the following items is not correct: "v1_sf12_itm9", "v1_sf12_itm10","v1_sf12_itm11","v1_sf12_itm12". Do not use these items for analysis.
