Participation Over Time
| Since the study spans such a long period of time, it was not
always possible to interview each one of the 399 teenage mothers, as well as all of their
children. As could be expected, people move around as time goes by, and in most cases
where we've lost track of someone, it's because they moved, and we weren't able to locate
them at their new addresses. We also learned of a number of deaths, which is inevitable
given the longitudinal nature of the study. There were however, some people that simply
didn't want to be involved with the study anymore - or in some cases, family members that
didn't want the participant to be involved, so they refused to let us contact them. And
then there were others that we were able to locate with the help of their friends and
family, but weren't able to contact for an interview directly because of their busy work
schedule, or because they were away from home (at college, in the military, etc.). Many of
these people were able to participate in future interviews, so they were not 'lost
forever' to our study. The table below gives the number of people that were absent from each Time, as well as the number of people that returned (people who had not taken part in the previous Time, but were able to participate at that particular Time). For an in depth description of the attrition in this study, please refer to our working papers section. Codes used in the table below are defined in the coding key. |
