Survey Items: K2Q35A; K2Q35B
Denominator: CSHCN age 2-17 years
Numerator: Do not have condition; Had condition at some point, but not currently; Currently have condition
Revisions and Changes: In 2009/10, significant changes were made to the wording of the introduction respondents heard prior to answering questions K2Q31A through K2Q52A. In 2005/06, parents were asked if “to the best of your knowledge, does [child] currently have…”. In 2009/10, the introduction was changed to “For each condition, please tell me if a doctor or other health care provider ever told you that [CHILD] had the condition, even if (he/she) does not have the condition now.” Take these changes into consideration when comparing results across survey years.
Additional Notes:
Treatment of Unknown Values: Unknown values (responses coded as 'refused', 'don't know', or system missing) are not included in the denominator when calculating prevalence estimates and weighted population counts displayed in the data query results table. In nearly every case, the proportion of unknown values is less than 1% and the exclusion of these values does not change the prevalence estimates (%) and only marginally affects the weighted population counts (Weighted Est.). Exceptions are noted in the form of a Data Alert at the bottom of a results table.
History and Development: The Maternal and Child Health Bureau leads the development of the NS-CSHCN survey, indicators and performance measures, in collaboration with the National Center for Health Statistics (NCHS) and a national technical expert panel. The expert panel includes representatives from other federal agencies, state Title V leaders, family organizations, and child health researchers. Previously validated questions and scales are used when available. Respondents’ cognitive understanding of the survey questions is assessed during the pretest phase and revisions made as required. All final data components are verified by NCHS and DRC/CAHMI staff prior to public release.
C.I. = 95% Confidence Interval. Percentages and population estimates (Pop.Est.) are weighted to represent child population in US.
