AddHealth data sample description

Summary: To conduct my research I selected AddHealth as a data sample to study research question ”Does having lot of energy help you to get started doing things?”

Sample: AddHealth is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-95 school year. Participants including adolescents, their fellow students, school administrators, parents, siblings, friends, and romantic partners.

Study includes five phases to follow respondents growing up. Participants has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. Number of participants vary between phases, new respondents were added and some respondents was not included anymore. Number of participants in each wave was different (Wave 1= 6504, Wave 2= 4834, Wave 3= 4882  and Wave 4= 5114).

Data analysis: In my data analysis sample I have included everyone in Wave 1 (N=6504) to research connection between variables ”You have a lot of energy” and ”It was hard to get started doing things”.
