本研究旨在探究女同志與前伴侶分手後的關係連結、社會支持與分手調適之關聯性。研究對象招募自我認同為女同志者，研究工具為：「分手後關係連結量表」、「社會支持量表」與「分手調適量表」等三項，問卷預試後由網路蒐集到938份有效問卷，並以獨立樣本t檢定、單因子變異數分析、皮爾森積差相關及多元迴歸進行分析。研究結果發現：（1）分手距今時間愈短、目前沒有伴侶與協商分手者，更傾向與前任伴侶聯繫；（2）20歲以上、交往時間愈長、分手次數愈多、目前有伴侶者，所獲得之社會支持較高；（3）20歲以下、交往時間短、分手次數較少者，分手後較具困惑感；（4）分手次數較多、分手距今較久、目前有伴侶者，有更正向之分手調適；（5）分手後與前任聯繫程度愈高者，具較高程度之痛苦、困惑與懷疑自我價值，及較多之愧疚與自責；與前任聯繫程度較低者，較易走出傷痛、肯定與瞭解自我價值及回到原本生活；（6）「分手後關係連結」與「社會支持」對「分手調適」多數向度具顯著預測力。最後根據結果提出建議，提供實務工作及未來研究者進行參考。

The purpose of this study was to investigate the association among relational boundaries with an ex-partner, social support and adjustment to a breakup among lesbian individuals. The participants, who identify as lesbian were assessed with Post-Breakup-Connectedness- Attitudes Scales, Scale of Social Support and Scale of breakup adjustment. After the pretest, 938 online questionnaires were collected in LGBT community and analyzed by descriptive statistics, one-way ANOVA, Person’s correlation and multiple regression. The results demonstrated that: (1) individuals who were not currently in a relationship, had a shorter time since the breakup, and negotiated the breakup were more likely to maintain contact with their ex-partner; (2) individuals aged over 20, with a longer dating time, more breakups, and currently in a relationship tended to have more social support; (3) individuals aged below 20, with a shorter dating time and fewer breakups, tended to feel more confused after a breakup; (4) individuals with more breakups, a longer time since the breakup, and currently in a relationship tended to have a positive adjustment after a breakup; (5) the more contact with ex-partner, the more likely it was to experience more pain, confuse, self-doubt, guilt and self-blame, while the less contact with ex-partner, the more likely it was to experience self-affirmation and to get through pain, to understand self-worth, and to return to normal life; (6) relational boundaries and social support among lesbians individuals significantly predicted breakup adjustment. Finally, suggestions for counselors and further researchers are offered.
