Codes and Frequencies
For sample children age 17 and under who are limited in their ability to do things children of the same age can do (CHLIMIT), CHLIMITHC reports parents' responses to the question, "Is this because of any medical, behavioral or other health condition?"
Rationale for Inquiry
CHLIMITHC was part of the Children with Special Health Care Needs (CSHCN) Supplement included in the Sample Child Health Care Access and Utilization section of the NHIS.
Before beginning this part of the survey, interviewers read the following statement:
CHLIMIT and CHLIMITHC were items in the section of the CSHCN dealing with "Functional Limitations." Respondents who answered "yes" to CHLIMITHC received the follow-up question, "Is this a condition that has lasted or is expected to last for at least 12 months?" (CHLIMITYR).
The 2002 Field Representative's Manual provides the following information regarding the purpose of the CSHCN Supplement:
- Growth or physical development
- Abilities and activities at school or play
- The kind or amount of services needed or used
According to the 2002 Survey Description, the CSHCN Supplement was included in the NHIS "to compare the results of a face-to-face in-home interview as conducted by the NHIS with a random digit dial telephone interview as conducted by NCHS's State and Local Area Integrated Telephone Survey (SLAITS)." The Survey Description also notes that the special needs questions included in the 2001 SLAITS and 2002 NHIS were taken from a standardized screener developed by the Foundation for Accountability (FACCT). The Child and Adolescent Health Measurement Initiative (CAHMI), in collaboration with FACCT, provides further information on this screener on their website at http://www.cahmi.org, including scoring procedures used to identify children with special health care needs.
For more information on the other CSHCN Supplement items and for scoring procedures, see CHNEEDRX. As noted, CHLIMIT, CHLIMITHC, and CHLIMITYR were items in the section of the CSHCN dealing with "Functional Limitations." Children with affirmative responses in all three variables satisfied the criteria for children with special health care needs in the domain "functional limitations" (a "yes" value in the IPUMS NHIS-created variable SPNEEDLIM).
