THE CHANGING LIVES OF OLDER COUPLES STUDY

 

MACBAT HEALTH FOLLOW-UP STUDY

 

CODEBOOK FOR ALL WAVES OF THE STUDY

 

APRIL, 1991

 

 

 

 

                        GENERAL CODING INSTRUCTIONS

 

 

 

  1.  Code Seq. # on Facesheet as the Case ID.

 

 

  2.  Ranges are not acceptable at any location in the Interview.  If you come across a range, see Supervisor.

 

 

  3.  Interviews will have been edited, and some items "scored", in green by the Study staff prior to the coding process.  If editing conflicts with the DDE specifications, see Supervisor.

 

 

  4.  Although not indicated in the codebook or on the screens, many variables are coded to one decimal place (e.g., A1c, A2).  The DDE program will convert these 3-digit fields, but care must be taken to enter the correct values, usually involving the insertion of a lead 0--e.g., 4.3 seconds must be entered as 043.
