6-month-old infants selected on irritability shortly after birth and their mothers were randomly assigned to 2 intervention and 2 control groups to test the hypothesis that enhancing maternal sensitive responsiveness will improve quality of mother-infant interaction, infant exploration, and attachment. The intervention lasted 3 months and ended when the child was 9 months of age. When infants were 9 months of age, intervention group mothers were significantly more responsive, stimulating, visually attentive, and controlling of their infant's behavior than control group mothers. Intervention infants had higher scores than control infants on sociability, self-soothing, and exploration, and they cried less. Quality of exploration also improved, with intervention infants engaged in cognitively sophisticated kinds of exploration more than control infants. At 12 months of age, significantly more intervention group dyads were securely attached than control group dyads.

One hundred planned lesbian-parent families (i.e., two-mother families in which the child was born to the lesbian relationship) were compared with 100 heterosexual-parent families on child adjustment, parental characteristics, and child rearing. Questionnaires, observations, and a diary of activities were used to collect the data. The results show that especially lesbian social mothers (i.e., nonbiological mothers) differ from heterosexual fathers on parental characteristics (e.g., more parental justification and more satisfaction with the partner as coparent) and child rearing (e.g., more parental concern and less power assertion). Child adjustment is not associated with family type (lesbian-parent families vs. heterosexual-parent families), but is predicted by power assertion, parental concern, and satisfaction with the partner as coparent.

The present study examined consistency of temperament across situations and time in early childhood. On two occasions, 7 months apart, we observed the responses of 94 four-year-olds to multiple standard laboratory procedures eliciting exuberance, fear, anger, sadness, or interest. In addition, fathers' and mothers' reports on children's temperament were obtained. Observed temperament showed substantial context specificity, varying across situations within dimensions. Structural equation models revealed separate observation and parental perception factors and factorial invariance and high stability for most dimensions. Stability coefficients based on correlations varied according to level of aggregation. Measurement convergence was generally moderate and was lowest for negative emotionality. Implications for the assessment of temperament are discussed in relation to differences in consistency across dimensions and convergence between measures.

The aim of this study was to explore the relationship of minority stress with experiences of parenthood (e.g. parental stress and parental justification) and child adjustment in lesbian mother families. Three components of minority stress were examined, namely, experiences of rejection as a result of the non-traditional family situation, perceived stigma, and internalized homophobia. A total of 100 planned lesbian families (100 biological mothers and 100 social mothers) were involved in this study. Data were collected by means of a written questionnaire. The lesbian mothers in this sample generally described low levels of rejection, they perceived little stigmatization, and they also manifested low levels of internalized homophobia. However, minority stress was significantly related to experiences of parenthood. Lesbian mothers with more experiences of rejection experienced more parental stress, and appeared to defend their position as mother more strongly (e.g. parental justification). Furthermore, mothers with higher levels of perceived stigma and internalized homophobia felt significantly more often that they had to defend their position as mother. Finally, mothers who reported more experience of rejection were also more likely to report behaviour problems in their children. Our findings emphasize the importance of the effect of minority stress on the lives of lesbian mothers and their children.

There are few differences between lesbian couples and heterosexual couples, except that lesbian mothers appear less attuned to traditional child-rearing goals and lesbian social mothers appear more to defend their position as mother.
