The study examined the association between basic need satisfaction in the couple relationship (basic need satisfaction in the relationship [BNSR]) and personal growth (PG), using a sample of 57 lesbian mothers individually matched with 57 heterosexual mothers. BNSR was found to correlate positively with growth only among lesbian mothers, while no significant association was found among heterosexual mothers. The findings are explained in terms of the particular characteristics of lesbian couples, such as high emotional support, equal division of labor, and absence of traditional gender roles. The potential contribution of these features to PG in the context of lesbian motherhood, which is planned, intentional, and often achieved after contending with minority stress and challenging life circumstances, is discussed.
