Personal mastery and psychological well-being among young grandmothers.

This study examined the association between relationship quality, personal mastery, and psychological well-being among 83 young Black and White American grandmothers in families with teenage mothers. Interviews were conducted during the early stages of adaptation to grandparenthood due to the birth of a baby to a teenage daughter. Findings indicated that the effects of the mother-daughter relationship are mediated through mastery. When grandmothers feel a sense of mastery, the conflict with the teenage mother is not as detrimental to their psychological health. Findings are discussed in the context of developing supportive services for grandmothers in families with teenage mothers.
