NHATS Data and Documentation Update2/6/2018

Helper Coding

The variable op#paidhelpr is inconsistently coded for helpers where op#relatnshp is 31 (PAID AIDE/ HOUSEKEEPER/ EMPLOYEE) in the Other Person (OP) file. In rounds 3, 4, and 6 it is coded as inapplicable and in rounds 1, 2, and 5 it is coded as paid. To correct the inconsistency, we recommend recoding op#paidhelpr as follows in rounds 3, 4 and 6 (where #=the round being recoded). Stata: replace op#paidhelpr=1 if op#ishelpr==1 & op#relatnshp==31 & r#dresid!=6 SAS (within Data proc): if op#ishelpr=1 and op#relatnshp= 31 and r#dresid ne 6 then op#paidhelpr=1;
