Description
TBSICKAIR indicates whether the respondent believed TB can be spread by breathing the air around a person who is sick with TB. In 1994 and 1995, this question was asked of sample adults who reported knowing "a lot," "some," or "a little" about tuberculosis (TB) (TBKNOW) and who responded, "Yes" to the question, "Do you know how TB is spread from one person to another?"(TBKNOWSPRED). From 2000 forward, this question was asked of sample adults who reported knowing "a lot," "some," or "a little" about tuberculosis (TB) (TBKNOW) and who responded, "Yes" to the question, "Have you ever heard of tuberculosis?" (TBHEARD).
Data Collection Methods
The basic methodology employed to collect the information in TBSICKAIR was similar in 1994-1995 and 2000 forward, but the details differed slightly between the two periods.
In 1994 and 1995, interviewers asked, "As you understand it, how is TB spread from one person to another?" Respondents were then handed a card with five specific choices (including "breathing the air around a person who is sick with TB") plus "other." (The categories were read to respondents for phone interviews.) The survey form directed interviewers to probe for additional answers by asking, "Any other way?"
From 2000 forward, interviewers asked, "How is TB spread?" Respondents were then handed a card with five choices (including "breathing the air around a person who is sick with TB") plus "other." From 2001 forward, the card included the statement, "You may choose more than one." The survey form directed interviewers to prompt for additional answers by asking, "Can TB be spread in any other way?" and to mark all categories chosen by the respondent.
While transmission via breathing the air around a sick person was included as a choice for both 1994-1995 and 2000 forward, the full range of choices for modes of TB transmision differed somewhat between the two periods.
In 1994 and 1995, other choices specified on the flashcard were:
- Through food and water (TBFOOD)
- By sexual intercourse (TBSEX)
- It is inherited from parents (TBINHERIT)
- From mosquito or other insect bites (TBINSECT)
- Other (TBOTHER)
From 2000 forward, other choices specified on the flashcard were:
- Sharing eating / drinking utensils (TBDISHES)
- Through semen or vaginal secretions shared during sexual intercourse (TBSEX)
- From smoking (TBSMOKE)
- From mosquito or other insect bites (TBINSECT)
- Other (TBOTHER)
