The project was started by Linda Bell in 1974 with a commitment to four primary goals:

1. To study the relationship between family process and the individual development of family members, especially children.
2. To conceptualize and measure system-level variables to describe family structure and process.
3. To develop micro-analytic (phrase-by-phrase coding) and macro-analytic measures of interaction process. (And, in general to create and use less obvious, more indirect measures of family system variables.)
4. To study a population of normal (i.e., non-clinical) families.

Wave 1 Home Interviews

In 1975 and 1976, structured home interviews were conducted with 99 middle-class families with adolescents. The home interview included marital and family revealed difference exercises, and a projective family task, the Family Paper Sculpture, created for the project. Marital and family interaction process were coded on two coding schemes (micro-analytic and global) which were also created as part of the project.

Wave 2 Telephone Interviews

From 1998 to 2002, telephone interviews were conducted with 174 now adult former adolescents (G2s) and 132 of their parents (G1s). These interviews focused on adult child - elder parent relationships and on mid-life psychological well-being.

Wave 2 Home Interviews

Home interview were conducted (2000 - 2002) with 42 now late life couples (G1s), and (1999 - 2002) with 46 families of the (now adult) adolescents from the original study (G2), with their own teenage children (G3). The marital home interviews included a repeat of a marital revealed difference exercise from Wave 1. The family home interview was basically a repeat of the Wave 1 interview, with the people who were adolescents at Wave 1 being the parents at Wave 2. We are hoping to conduct an additional 30-40 G2-G3 family home interviews as the young children in these families become adolescents.

Research

We have focused on the importance of two factors (the family climate and the adolescent's role in the family) on the adolescent's individual development and peer relationships. We have also conducted cross-cultural studies of marriage and family, comparing Japanese and US families. Methodological analyses of interaction process measures and cross-cultural research methods have been conducted. Analyses in this prospective longitudinal study of normal US families is focusing now on (1) the effects of the adolescent family experience on mid-life well-being, (2) mid-life relationships with elder parents, (3) marriage from mid-life to later life, and (4) intergenerational family patterns. Primary organizing constructs are connection and individuation processes.

Other Samples

[Data on 38 working-class couples (half of whom had had a child removed because of abuse) were collected in 1980-82 in Texas.] Data from home interviews with Japanese families, comparable to the U.S. family data, were collected during a two-year stay (1985-87) at the Japanese National Institute of Mental Health. Using the same research design as for U.S. families, home interviews were conducted with 60 Japanese families with adolescents.

Support

The project has received financial support over the years from the U.S. National Institute of Mental Health, the Japanese National Institute of Mental Health, the Hogg Foundation for Mental Health, the Japan Foundation, the Texas Higher Education Coordinating Board, the University of Chicago, the Family Institute at Northwestern University, and the University of Houston - Clear Lake.
