WLS Codebooks

Note: Codebooks contain frequency data from the private data release. For some variables, these differ from the frequencies in the public release. Variables that differ between the public and private versions include "(not available on public release)" as part of the variable description, or a note indicating the difference between the public and private versions.

Status and Descriptive Variables

Status and Descriptive Variables Module


OVERVIEW

This module includes participation status variables for each wave and a few
measures, such as sex and birthdate, that do not change across waves.  This
module also contains information on the mortality status of Graduates and
Siblings.

Similar variables for spouses are in the summary modules for the spouse
codebook, since the spouse may change. 

For graduate spouse
see
grad spouse summary.

For sibling spouses see
sib spouse summary.

If the Medicare Part D SAQ was not returned (codes 13 or 20) and later we learned that the respondent was deceased prior to 2006 (from source such as Social Security Death Index), the case was assigned code 7. Code 7 also includes those who were reported as deceased during fielding period, mostly from information provided in the returned mail. Prior to release 13.02, non-contact cases (codes 13 and 20) were recoded to 7 if the respondents were found to be deceased from the latest Death Index search. In release 13.02, we do not recode non-contact cases (codes 13 and 20) that might have been deceased during fielding period (2006-2008) to code 7, unless the deaths were reported by informants. Instead, see DEATYR for respondent's year of death.

Some of the deaths reported from the returned mail cannot be verified. We have discovered some cases of false report of death. The status of such cases have been changed to refusal (code 6).

Participants who completed the telephone version of the interview instead of the in-person version were mailed a SAQ. Additionally, participants who declined the in-person interview and the alternate telephone interview were mailed a modified version of the self-administered-questionnare. We refer to this instrument as Mail Only Self-Administered Questionnaire or MOSAQ. Participants who started the in-person or telephone interview but did not finish the interview were also mailed the MOSAQ.

Some of the respondents who had donated saliva in 2008 might be asked to donate again if the amount of saliva collected in the last wave was deemed insufficient or of poor quality. Instrument error also resulted in repeated request for some cases.

Only respondents who have completed either CAPI or Mail-Only SAQ are eligible for request.

Note: Some sibling respondents have duplicates in the data (see XSIBSTAT for various types of duplicates). This variable can be used with XDUPID and DUPID to locate the duplicate records. If the variable has a positive value, the selected sibling in the corresponding record has a duplicate. The positive value indicates whether the duplicate of current sib record is in the grad or sib section of the other record; this duplicate record can then be located by matching the XDUPID of current record with the DUPID or XDUPID of all the other records (see note for XDUPID for an example).

All graduate respondents' duplicates (if any) are selected siblings and therefore there is no corresponding version of the variable for the graduate.

Note: This variable can be used with XDUPRTP and DUPID to locate the duplicate record. Use XDUPRTP to determine whether the duplicate of current sib record is in the grad or sib section of the data set, and then use XDUPID to search for matching DUPID (if XDUPRTP=1) or XDUPID (if DURRTP=2) among all other records. For example, for any pair of two different records I and J, if the sib of I has a duplicate as a grad (XDUPRTP=1) and XDUPID=N, the grad record of J with DUPID=N and I's sib are each other's duplicates. On the other hand, if the sib record of I has a duplicate also as a sib (XDUPRTP=2) and XDUPID=M, the sib record of J with XDUPID=M and I's sib are each other's duplicates.

3 Selected sib also a grad, reciprocal selected sib 12 24 36
Note: If a selected sibling is shared by two graduates, and therefore represeted by two sibling records, the XSIBSTAT of one sibling record is coded 0 while the other coded 1. From the 2008 on, the sibling records with XSIBSTAT=0 are designated as the primary records. In cases where XSIBSTAT is equal to 2 or 3 (siblings who are also graduates), the graduate records are always the primary records. Beginning from the 2008 Biomarker data collection, only the IDs of the graduate and the primary sibling records were used for survey data collection, so each respondent was interviewed only once. In the post-survey data processing, data from the primary records were then copied to the duplicate records.

In the complete data set, xsibstat=-2 if the graduate does not have any sibling or never provided information about any individual sibling.

Note: New codes were assigned in the 3/96 release to distinguish between those siblings who completed the phone and mail interviews and those who only completed the mail interview.

All siblings who were interviewed in 1977 and all siblings of respondents who completed the telephone interview in 1992/93 were scheduled to be interviewed by telephone in 1993-1994. Addtionally, siblings who completed the 1993/94 telephone interview were to be sent a mail questionnaire. Due to budget constraints, it was not possible to complete all these interviews. Telephone interviews were attempted for all those siblings who were interviewed in 1977 (XSTAT77=1) and for all other siblings from groups (GROUP91) 2-9 (if the respondent completed a telephone interview in 1992/93). Mail questionnaires were sent to the remaining 970 siblings from groups 0 and 1 (if the respondent completed the telephone interview). These mail questionnaires contained two additional pages ascertaining information about marriage, current job, children, birthdate, education and spouse's job. 559 of these siblings returned the mail questionnaire (XSTAT93M=2).

For the 3/97 edition nine 1975 primary respondents who were also selected siblings had their data carried over to the 1977 selected sibling section. See Change Notice #6 for details.

Frequencies are displayed for the sibling's gender.

Participants who completed the telephone version of the interview instead of the in-person version were mailed a SAQ. Additionally, participants who declined the in-person interview and the alternate telephone interview were mailed a modified version of the self-administered-questionnare. We refer to this instrument as Mail Only Self-Administered Questionnaire or MOSAQ. Participants who started the in-person or telephone interview but did not finish the interview were also mailed the MOSAQ.

24 Not fielded, no further contact request prior to fielding 19 21 40
Note: On public release, codes 8 and 13 are collapsed into code 13.

If the Oragene kit was not returned (codes 13 or 20) and later we learned that the respondent was deceased prior to 2006 (from source such as Social Security Death Index), the case was assigned code 7. Code 7 also includes those who were reported as deceased during fielding period, mostly from information provided in the returned mail. In this measure, we do not attempt to recode non-contact case (codes 13 and 20) that might have been deceased during fielding period (2006-2008) to code 7, unless the deaths were reported by informants. See XDEATYR for respondent's year of death.

Some of the deaths reported from the returned mail cannot be verified. We have discovered some cases of false report of death. The status of such cases have been changed to refusal (code 6).

This measure is based on the same information used to construct the XSTATKDNA released in versions prior to 13.02. In release 13.02, XSTATKDNA has been updated to include cumulative status from all waves of biomarker collection.

If the Oragene kit was not returned (codes 13 or 20) and later we learned that the respondent was deceased prior to 2009 (from source such as Social Security Death Index), the case was assigned code 7. Code 7 also includes those who were reported as deceased during fielding period, mostly from information provided in the returned mail.

Note: On public release, codes 8 and 13 are collapsed into code 13.

If the saliva consent form was not returned (codes 13 or 20) and later we learned that the respondent was deceased prior to 2006 (from source such as Social Security Death Index), the case was assigned code 7. Code 7 also includes those who were reported as deceased during fielding period, mostly from information provided in the returned mail. In this measure, we do not attempt to recode non-contact case (codes 13 and 20) that might have been deceased during fielding period (2006-2008) to code 7, unless the deaths were reported by informants. See XDEATYR for respondent's year of death.

Some of the deaths reported from the returned mail cannot be verified. We have discovered some cases of false report of death. The status of such cases have been changed to refusal (code 6).

This measure is based on the same information used to construct the XSTATCDNA released in versions prior to 13.02. In release 13.02, XSTATCDNA has been updated to include cumulative status from all waves of biomarker collection.
