Widening the lens on family processes and the development of parent-child attachment relationships.

This commentary addresses the research conducted by McConnachie et al. (this issue) on attachment in gay father families, lesbian mother families, and heterosexual parent families. Strengths of the research included the inclusion of different family constellations, the focus on between-family and within-family differences, the longitudinal research design, and the age-appropriate assessment of attachment. Some limitations noted included the lack of control for age at adoption in analyses, the lack of information on parenting processes and parental mental health in the formation of attachment, and questions about information obtained from parent reports of children's prior caregiving histories.
