Sexting as a mechanism for the role of alcohol in sexual assault

描述(由申请者提供)：这个项目将研究性短信(通过手机交换性暗示短信或图片)和有问题的酒精使用如何增加大学女性[危险的性行为和性侵犯]的风险。我的综合因果路径模型包括(A)与冲动相关的人格特征--感觉寻求和消极紧迫感--以及(B)对饮酒和性行为的预期，这两者都与饮酒、性短信、[危险的性行为]和性侵犯有关(例如，Corbin等人，2001；Dir等人，[2013a，审查中；Dir&Cyders，审查中])。 尽管得到了横断面数据的支持(Dir等人，[2013a])，但研究尚未在前瞻性框架中检验我的综合因果模型。这项拟议的项目将包括两个方面：(1)对大学两个学期的女大学生的行为进行纵向分析(如之前所做的：F31，PI：Cyders 2006-2009)，以及(2)对男大学生和女大学生对性短信遭遇的解读的实验分析。为了测试我的酒精使用和[危险性行为，以及性]攻击风险的综合和预期模型，我将使用多种评估方法(结合自我报告数据、小插曲、每日日记报告和短信电话审查)。主要的研究假设是：(1)性短信在大学女性中调节了酒精使用与[高风险的性行为和]性侵犯之间的关系(研究1)；(2)冲动相关的特征和与性相关的酒精预期预测了大学女性的酒精使用，以及随后的性短信、[高风险的性行为和性]攻击(研究1)；以及(3)男性和女性在性短信和酒精使用行为中对隐含信息的不同解读，导致性侵风险的增加(研究2)。鉴于大学女生使用手机和酗酒的高流行率，需要将这些因素综合起来预测[危险的性行为和性侵]的模型，以便有效地干预这一高危群体。成功地证明这一风险模型将推动这一领域的研究，并有助于制定更有效的干预和预防战略，包括基于移动电话的预防技术。

DESCRIPTION (provided by applicant): This project will address how sexting (the exchange of sexually suggestive texts or pictures via mobile phone) and problematic alcohol use together increase the risk for [risky sexual behavior and sexual] assault among college women. My integrated causal path model includes (a) impulsivity-related personality traits - sensation seeking and negative urgency - and (b) learned expectations about alcohol use and sexual activity, both of which are related to alcohol use, sexting, [risky sexual behavior,] and sexual assault (e.g., Corbin et al., 2001; Dir et al., [2013a, under review; Dir & Cyders, under review]). Although supported by cross-sectional data (Dir et al., [2013a]), research has yet to examine my integrated causal model in a prospective framework. The proposed project will be two-fold: (1) A longitudinal analysis of college women's behaviors over two semesters of college (as previously done: F31, PI: Cyders 2006-2009), and (2) an experimental analysis of male and female college students' interpretations of sexting encounters. In order to test my integrative and prospective model of alcohol use and [risky sexual behavior, and sexual] assault risk, I will use multiple methods of assessment (combining self-report data, vignettes, daily diary reports, and text message phone review). The main study hypotheses are: (1) Sexting mediates the relationship between alcohol use and [both risky sexual behavior and] sexual assault among college women (Study 1); (2) Impulsivity-related traits and sex-related alcohol expectancies prospectively predict alcohol use, and subsequent sexting, [risky sexual behavior, and sexual] assault among college women (Study 1); and (3) Males and females differentially interpret implicit messages in sexting and alcohol use behaviors, leading to increased risk for sexual assault (Study 2). Given the high prevalence of mobile phone and alcohol use among college women, models integrating these factors in predicting [risky sexual behavior and sexual] assault are needed in order to effectively intervene on this high-risk group. Successfully demonstrating this risk model would advance research in the field and inform the development of more effective intervention and prevention strategies, including mobile phone-based prevention techniques.
