Gay and lesbian couple relationship commitment in taiwan: a preliminary study.

Due to the traditional values on marriage and heterosexual relationships, gay and lesbian couple relationships were long ignored in Taiwan. This study attempted to look at gay and lesbian couple relationship commitment. Questionnaires were used in this study. Due to the difficulties of getting gays and lesbians to participate in research, snowballing method was used. The sample included 218 participants in a stable couple relationship for at least six months. Through multiple regression analyses, the result showed that the influencing factors of gay and lesbian couples' commitment fit Rusbult's Investment Model closely.
