The 2006 wave of the HRS included one of these new “modules” that focused on respondents’ life satisfaction and a wide range of related measures of psychological well-being. This module (the “Leave-Behind Participant Life Style Questionnaire”; see Clarke et al. (2007) for further information) was administered at random to the half sample of participants who completed a face-to-face 2006 core survey. Specifically, there were 8,566 eligible respondents for the 2006 Leave-Behind Questionnaire. The completion rate was about 86%. Consequently, 7,365 respondents completed the questionnaire (we exclude 97 cases that were completed by someone other than the assigned respondent).
