The present study examined a motivational pathway model whereby the relation between binegativity and alcohol-related problems was mediated by drinking to cope motives and alcohol consumption. The moderating role of impulsivity on the associations between binegativity, drinking to cope motives, and alcohol use outcomes was also examined. Data were collected from 225 self-identified bisexual women between the ages of 18 to 30 (M = 22.77, SD = 3.45) who participated in an online survey. Participants reported on their experiences of binegativity, drinking to cope motives, alcohol consumption, alcohol-related problems, and impulsivity. Results revealed that drinking to cope motives and alcohol use sequentially mediated the relation between binegativity and alcohol-related problems. Thus, greater binegativity was related to greater alcohol-related problems through greater drinking to cope motives and subsequent elevated alcohol consumption. Impulsivity significantly moderated the relation between drinking to cope motives and alcohol-related problems, whereby the positive association between drinking to cope motives and alcohol-related problems was stronger for those who reported greater impulsivity. Although binegativity and impulsivity were positively related, impulsivity did not moderate the associations between binegativity, drinking to cope motives, alcohol use, and alcohol-related problems. Findings from this study highlight binegativity and impulsivity as independent predictors of risky alcohol use behaviors. Such information could aid prevention and intervention programs aimed at reducing alcohol-related risks among bisexual women.

本研究检查了一个动机途径模型，其中双负性和酒精相关问题之间的关系是通过饮酒来应对动机和饮酒来调节的。还检查了冲动对双负性、饮酒以应对动机和酒精使用结果之间关联的调节作用。数据收集自 225 名年龄在 18 至 30 岁之间的双性恋女性（M  = 22.77，SD = 3.45）谁参加了在线调查。参与者报告了他们的消极情绪、饮酒以应对动机、饮酒、与酒精有关的问题和冲动的经历。结果表明，为应对动机而饮酒和饮酒依次介导了负面情绪与酒精相关问题之间的关系。因此，更大的负面情绪与更大的酒精相关问题有关，通过更多的饮酒来应对动机和随后的酒精消耗量增加。冲动性显着缓和了饮酒以应对动机和酒精相关问题之间的关系，因此对于那些报告更冲动的人来说，饮酒以应对动机和酒精相关问题之间的正相关性更强。虽然消极性和冲动性是正相关的，冲动并没有缓和负面情绪、饮酒以应对动机、酒精使用和酒精相关问题之间的关联。这项研究的结果强调了消极和冲动是危险饮酒行为的独立预测因素。这些信息可以帮助旨在减少双性恋女性酒精相关风险的预防和干预计划。
