Self-report data were gathered in an online survey by employing standard questionnaires from participants (N = 203) consisted of straight (n = 121) and LGBT (n = 82). Unexpectedly, results showed no correlations between Dark Triad traits and relationship satisfaction, but relationship length appeared to be associated with Dark Triad traits, as well as some positive and negative factors. This revealed the potential to further investigate in the future on the possibilities which relationship length might bring. This study also looked into the differences of gender and sexual orientation on all major variables, which showed some significant results but required further studies to prove them conclusive mainly due to the imbalance ratio of male and female in LGBT and straights in the sample.enHKSYU Theses
