Peer relationships are especially relevant during adolescence and may contribute to sexuality-based disparities in substance use. This study uses social network analysis to examine how social networks may serve as risk or protective factors for sexual minority youth in the context of alcohol use.
Social network analysis was applied to 11th to 12th graders in three diverse high schools in a rural area of the Southeast United States. The network consists of 1,179 students, 607 of whom were participants in the study and nominated friends. Regression models were used to examine how potential predictors of alcohol use may function differently for sexual minority and majority students.
Approximately one fourth of students were classified as sexual minorities, inclusive of students who self-identified or reported any same-sex romantic attraction or sexual experience. These students did not use alcohol in greater amounts than students in the sexual majority. They received fewer incoming friendship nominations (p < .05) although a higher percentage of friendships were reciprocated (p < .05). They exhibited lower eigenvector centrality (p = .01), and their networks were less cohesive (p < .001). However, low centrality and low density did not predict greater alcohol consumption. Sexual minorities appeared to be influenced less strongly by peers' alcohol use, and friendships with sexual minorities further mitigated peer influence.
Sexual minorities occupied less prominent positions within their social networks. However, these network differences did not place sexual minorities at increased risk of alcohol use.
同伴关系在青少年时期尤为重要,可能会导致基于性别的物质使用差异。本研究使用社会网络分析来研究在涉及酒精使用的情况下,社交网络如何成为性少数青年的风险或保护因素。
社会网络分析应用于美国东南部一个农村地区的三所不同高中的 11 至 12 年级学生。该网络由 1179 名学生组成,其中 607 名是研究参与者并提名了朋友。回归模型用于研究潜在的酒精使用预测因素如何对性少数和多数学生产生不同的作用。
约四分之一的学生被归类为性少数群体,包括自我认同或报告任何同性浪漫吸引力或性经历的学生。这些学生的酒精使用量并不比性多数群体的学生多。他们收到的友谊提名较少(p <.05),尽管有更高比例的友谊是互惠的(p <.05)。他们的特征向量中心度较低(p =.01),网络的凝聚力较低(p <.001)。然而,低中心度和低密度并不预示着更高的酒精消费。性少数群体似乎较少受到同伴酒精使用的影响,而与性少数群体的友谊进一步减轻了同伴的影响。
性少数群体在他们的社交网络中占据的地位不那么突出。然而,这些网络差异并没有使性少数群体面临更高的酒精使用风险。
