He was a member of the editorial boards of the "Journal of Family Theory and Review" and the "Journal of Marriage and Family". Education. Johnson obtained his BA degree in sociology from Knox College (Galesburg, Illinois) (1965), his MA in sociology  from the University of Iowa (1969), and his PhD in sociology from the University of Michigan (1974). PAIR project. In 1981 a long-term study of courtship and marriage of 168 couples was implemented by Ted Huston. The project began at Penn State and was intended to last through the first two and a half years of marriage, but it was extended and extra waves of data were collected. In 1985 the project transferred to the University of Texas at Austin and a follow-up set of interviews with the participants took place in 1991. Johnson has been a collaborator  on the PAIR project since its early days, with a particular interest in 'conceptions of commitment'. Johnson's typology.
