Codes and Frequencies
For sample persons under 5 years old in 1981 and persons aged 16-59 months in the 1994-95 National Health Interview Survey-Disability Survey (NHIS-D) Phase I sample, WALK2ALONEV reports if the child has ever walked at least 2 steps without holding on to anything or another person.
Child motor and social development variables should be combined with AGE, BIRTHMO (Month of birth), and INTERVWMO (Month of NHIS interview) to provide complete information about the child's developmental progress. For more information on how the child's specific age is relevant to this variable, please see HEADTURNEV.
In 1994 and 1995, this variable is part of the Disability Supplement (NHIS-D) that collects information on disability. NHIS-D included two household interviews: in Phase I all members of sample families were screened for any indication of disability; in Phase IIÂ persons with any indication of disability were followed-up for additional information. Phase I includes sensory, communication, and mobility problems; health conditions; activities of daily living and independent activities of daily living; functional limitations; mental health; services and benefits; special health needs of children; early child development; education; relationship to respondent; and perceived disability. Phase II includes four Disability Followback Survey (DFS) questionnaires: one for children, one for adults, one for elderly persons (69 years of age and over) without any indication of disability (also called the Supplement on Aging or SOA; only in 1994), and one for persons with a history of polio.
