We examined adult attachment styles, differentiation of self, and relationship satisfaction in a sample of 298 Italian lesbians (48%) and gay men (52%), all of whom were ages 19–71 years (M = 36.1; SD = 11.8) and in a couple relationship for at least six months. Participants were recruited via the Internet and completed a web-based survey. We tested the hypotheses that attachment insecurity and differentiation of self would predict relationship satisfaction, as well as that differentiation of self would mediate the relationship between adult attachment and relationship satisfaction. Results supported the hypotheses, thus indicating that attachment insecurity and differentiation of self were correlated with and predicted relationship satisfaction. Furthermore, results supported the hypothesized mediating role of differentiation of self. Finally, results indicated that younger participants, lesbians, and participants in civil unions reported higher levels of relationship satisfaction. Implications for counselors and therapists working with LG populations are discussed.

我们以298名意大利女同性恋者（48％）和男同性恋者（52％）为样本，研究了他们的成人依恋风格，自我分化和关系满意度，他们的年龄均在19-71岁之间（M  = 36.1；SD = 11.8），并且处于伴侣关系中至少六个月。通过互联网招募了参与者，并完成了基于网络的调查。我们检验了以下假设：依恋不安全感和自我分化将预测关系满意度，以及自我分化将介导成人依恋与关系满意度之间的关系。结果支持该假设，从而表明依恋不安全感和自我分化与预期的关系满意度相关。此外，结果支持了假设的自我分化的中介作用。最后，结果表明，较年轻的参与者，女同性恋者和公民工会的参与者报告了较高的关系满意度。
