It is survey for U.S. adolescents in 132 schools nationwide for students enrolled in grades from year 7 to 12 in 1994-1995 (Wave I), follow-up surveys in 1996 (Wave II), 2001-2002 (Wave III). An unusual feature of Add Health is that it not only collects extensive information on adolescents’ smoking behavior but it also gathers information on the characteristics on adolescents’ relationship with their nonresidential father and their conditions of involvement with their offspring. Sample for the analysis included all individuals that were younger than the age of 18 in Wave II who were interviewed in all of the 3 waves of the study. Adolescents were asked how close they were to their nonresidential fathers, ranging from 1 (not close at all) to 5 (extremely close), how often they had stayed overnight with him during the past year, from 0 (not at all) to 5 (more than once a week), and a series of nine questions about whether they had participated in various outgoing activities such as shopping, watching a movie, or working on a school assignment with their nonresidential father (1 = yes, 0 = no). These measures were then summed and standardized (to have a mean of 0 and a standard deviation of 1) to help create a measurement of nonresidential father involvement. There were many controls included in this study such as demographic
