Advantages:– Tracking form information is only entered in WinW3S– Instrument information is entered only in WinDEM– No double entry of hierarchical identification codes is

necessary– No empty instruments need to be entered in WinDEM

... is ensured by introducing the– CheckSum procedure– (WinW3S Linkcheck)

Linkage between WinW3S & WinDEM

Reduces mispunches, time, and costs


CheckSum is created for each unique identification code (ID)CheckSum is printed on all labels and tracking forms produced by WinW3SWinDEM accepts unique IDs only in combination with corresponding CheckSum

– 1 digit, avoid column shifts– Only entering blank space is allowed– Appear

- When transition is made between ID variables and TOKEN01 variables

- At the end of every odd numbered page and at the end of the questionnaire

Indicator Variables – I

• Identification variables• Indicator variablesIn all files:TOKEN01

– 1 digit, indicates availability of data– 3 codes possible

1 – Instrument available, but empty

2 – Instrument not available or lost 3 – Instrument available with responses
