Details

KSADS summary scores are mostly calculating the means over variables, but there are two special codes to handle:

  • "888": item skipped by branching. When at least one input value is observed, any 888 value is converted to "0" prior to averaging.

  • "555": module not administered. If any input variable is "555" leave the score as NA.

  • NA: missing value. If at least one input value is observed, any NA values are converted to "0" prior to averaging. If all inputs are NA, the summary score remains NA.
