Description

CLIMOTHDEVMO reports the duration, in months, of a limiting (non-mental retardation) developmental problem. This information is reported only for persons who had at least one activity limitation (LANY), and whose limitation was due to a (non-mental retardation) developmental problem not listed on the interviewer-provided flashcard (CLIMOTHDEV).

Data on the duration of the limiting other developmental problem were collected via the question, "How long [have/has] [you/person] had [a (non-mental retardation) developmental problem]?" Respondents could answer this open-ended question using the time unit of their choice (i.e., days, weeks, months, or years). The original responses to the question are reported in two complementary variables, CLIMOTHDEVTP (which specifies the time unit) and CLIMOTHDEVNO (which reports the number of such units). For the NHIS public use files, the National Center for Health Statistics (NCHS) recoded the results from these two variables to create two other variables using standard time units: years (CLIMOTHDEVY) and groups of months (CLIMOTHDEVMO).

Comparability

Apart from a change in the coding of "unknown" cases, this variable is comparable across years.

 

All "unknown" cases for this variable share a common first digit of "9." The meaning of the second digit following the 9 differs for 2001 versus 2002 forward. In the earlier period, the "unknowns" were categorized as:

  • Unknown number of days (IPUMS NHIS code 91)
  • Unknown number of weeks (IHIS code 92)
  • Unknown number of months (IHIS code 93)
  • Unknown number of years (IHIS code 94)
  • Unknown time with condition (IHIS code 95)

In the latter period, "unknowns" were categorized as:

  • Unknown-refused (IHIS code 97)
  • Unknown-not ascertained (IHIS code 98)
  • Unknown-don't know (IHIS code 99)

Analysts can achieve comparability across all years by combining codes with a common first digit of 9 into a single "unknown" category.
