Dynamics of families during the third trimester of pregnancy in southwest Finland.

Transition to a changed family structure during pregnancy brings into focus the family's dynamics. To describe these dynamics during the third trimester of a healthy pregnancy, the Family Dynamics Measure was administered to 136 mothers and 131 fathers in southwest Finland. Mothers and fathers reported differences in 4 of the 6 dimensions of family dynamics. Clearer communication was perceived by mothers of higher social status. Second-time parents perceived greater isolation and role conflict than first-time parents. Findings contribute cues for specific family guidance by nurses during the transition to parenthood regarding partner differences, parity and social status.
