Phone: Volunteering
SVOL Volunteer Module For more information on the Volunteer Module see Appendix G. OVERVIEW The Volunteer Module contains questions about sibling respondents' volunteer, blood donation, and caregiving activities. - Questions about volunteer and blood donation activities are new to the 2005 telephone instrument. Only respondents in the 79% random sub-sample were asked the questions about volunteering and blood donation. Variable cu001re is a flag from the Alcohol Module which equals 1 if respondents were in the sub-sample and 0 if they were not. - Questions about caregiving were introduced in 1994 and asked again in 2005. In 1994, questions about caregiving activities were contained in an independent Caregiving Module. Questions pertained to both care received by the respondent and care given by the respondent to a family member or friend. For the 2005 wave, respondents were only asked about care given to a family member or friend, and the questions are located within the Volunteer Module. Although some caregiving questions appeared in both waves, many of the questions used in 1994 were not repeated in 2005. Only the following variables, listed here as 1994 variable name/2003-05 variable name, appeared in both waves: sv016re-sv022re/cv016re-cv022re. Only respondents in the 79% random sub-sample were asked the questions about caregiving. Variable cu001re is a flag from the Alcohol Module which equals 1 if respondents were in the sub-sample and 0 if they were not. Religion, cognition, digit ordering, volunteer, alcohol and depression are asked of the same sample.
