Health prevents work For the 1996-2004 panels, information on work-preventing disability comes from core question edisprev during wave 2 for people ages 15-69, when respondents were asked whether health prevented work. This indicator is supplemented with details from the Functional Limitations and Disability topical module (wave 5 for 1996-2004 panels, variable ejobcant) that covers people ages 16-67. For the 1990-1993 panels, the core questionnaire does not ask respondents whether health prevents work. This information is solely obtained from the Functional Limitations and Disability topical module (waves 3, 3, 6, 3 for 1990-1993 panels, variables TM8922 and TM8924) that covers people ages 16-67. When available, the core and topical modules were used in conjunction to construct summary measures of disability, with any positive indication of health preventing work flagging the positive response. .=Structurally missing, out of scope for question (sum_disab_in_scope=0 or { sum_disab_in_scope=1, sum_disab=0}) 0=No (sum_disab=1) 1=Yes (sum_disab=1)
