Marital satisfaction across the transition to parenthood.

The purpose of the present study was to discriminate between the 2 dominant perspectives governing research on the nature of marital change over the transition to parenthood. Progress can be made in understanding this transition by recognizing the role of uncontrolled sources of variability in research designs, defining and using control groups, and timing of data collection around the child's arrival, and the authors conducted a study incorporating these methodological refinements. Growth curve analyses were conducted on marital satisfaction data collected twice before and twice after the birth of the 1st child and at corresponding points for voluntarily childless couples (N = 156 couples).

Recruitment and selection of couples for intervention research: achieving developmental homogeneity at the cost of demographic diversity.

Demographic and relationship quality data were collected from 704 individuals recruited to participate in a randomized study of relationship enhancing interventions. Recruiting at bridal shows produced partners who were more satisfied, earlier in their relationships, and less likely to be parents, with a marginally higher proportion of Latino couples. Radio and television coverage produced more established couples with higher levels of relationship discord.
