Codes and Frequencies
For Sample Adults age 18+ who, without using special equipment, had any difficulty with one or more functional activities (FLANY), and whose limitation was due to an other (non-mental retardation) developmental problem not listed on the interviewer-provided flashcard (CLIMOTHDEV), FLOTHDEVTP reports the time unit in which the duration of the other developmental problem (e.g., cerebral palsy) was measured by the respondent.
Data on the duration of the limiting other (non-mental retardation) developmental problem were collected via the question, "How long have you had [an other developmental problem]?" Respondents could answer this open-ended question using the time unit of their choice (i.e., days, weeks, months, years, or since birth). The original responses to the question are reported in two complementary variables, FLOTHDEVTP (which, as noted above, specifies the time unit) and FLOTHDEVNO (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 (FLOTHDEVY) and groups of months (FLOTHDEVMO).
