Intimate partner violence in newly married couples: The role of illicit drug use.

描述（由申请人提供）：非法药物使用（IDU）和亲密伴侣暴力（IPV）是重要且相互关联的公共卫生问题。有强有力的证据IDU和IPV之间的横截面关联，但缺乏研究测试纵向关联和潜在的中介/调节效应。伦纳德（1993）提出了一个物质使用与IPV之间关联的启发式模型，即远端风险因素（如反社会人格、敌意）与近端风险因素（如情境线索、物质使用的精神药理学效应）相结合，增加了暴力事件的可能性。实验证据表明，不同的非法药物类型（即大麻，可卡因）的精神药理学影响引起的攻击行为是模棱两可的，这表明它是重要的研究更远的影响IDU。以前的研究推测，IDU可能会增加人际关系中的言语冲突，这反过来又会导致IPV的可能性更大。许多其他变量（例如，敌意、回避应对、生活压力、种族、反社会人格、饮酒和伴侣IDU）被认为是可能的关联调节因素;然而，缺乏直接测试这些影响的研究。本研究将使用二手数据分析来检验IDU和IPV之间的纵向关联以及中介\调节效应。为此，将分析来自成人发展研究（ADS）的数据，这是一项对纽约州布法罗新婚夫妇的纵向调查。对新婚夫妇的IPV研究尤为重要，因为这一人群的IPV率很高。夫妇们在申请结婚证时被招募参加ADS，随后在他们的第一、第二、第四、第七和第九个结婚纪念日进行随访。重要的是将样本限制在结婚初期，同时保留足够的时间点进行有意义的纵向分析;因此，将仅分析前四波（即基线至4周年）的数据。ADS数据收集自634对夫妇的配偶双方，使这项拟议的研究，以检查潜在的重要影响，合作伙伴的行为关系暴力。重要的是首先检查与以前研究结果的一致性;因此，本研究的第一个具体目的是检验IDU和IPV之间的横断面关系。第二个具体目标是检查新婚夫妇中丈夫/妻子IDU和丈夫/妻子IPV之间的纵向关联。第三个具体目标是测试IPV-IDU关联的可能的中介者/调节者，包括：a）伴侣IDU的调节效应，B）言语冲突的调节效应，以及c）敌意、回避应对、生活压力、反社会人格、饮酒和种族/民族的调节效应。将使用描述性统计、卡方检验、t检验和逻辑回归来检查样本中IDU和IPV的患病率，并检验IDU和IPV之间的横截面关系。多层次模型将被用来测试的纵向关系IDU和IPV，以及中介和缓和的影响。

DESCRIPTION (provided by applicant): Illicit drug use (IDU) and intimate partner violence (IPV) are important and interrelated public health issues. There is strong evidence for a cross-sectional association between IDU and IPV, but there is a shortage of research testing a longitudinal association and potential mediation/moderation effects. Leonard (1993) proposed a heuristic model of the association between substance use and IPV, whereby distal risk factors (e.g. antisocial personality, hostility) in conjunction with proximal risk factors (e.g. situational cues, psychopharmacological effects of substance use), increase the likelihood of violent events. Experimental evidence that the psychopharmacological effects of different illicit drug types (i.e. cannabis, cocaine) elicit aggressive behavior is equivocal, suggesting that it is important to research more distal effects of IDU. Previous research has speculated that IDU may increase verbal conflict in relationships, which in turn can result in a greater likelihood of IPV. A host of other variables (e.g., hostility, avoidance coping, life stress, race, antisocial personality, alcohol use and partner IDU) have been suggested as possible moderators of an association; however, there is a lack of research that directly tests these effects. This proposed study will use secondary data analysis to test a longitudinal association between IDU and IPV, and mediation\ moderation effects. To do so, data will be analyzed from the Adult Development Study (ADS), a longitudinal survey of newly married couples in Buffalo, NY. Research on IPV among newly married couples is particularly important because rates of IPV are high in this population. Couples were recruited for the ADS as they applied for their marriage license, and subsequently followed-up at their first, second, fourth, seventh and ninth wedding anniversaries. It will be important to limit the sample to the early years of marriage while retaining enough time-points to conduct meaningful longitudinal analyses; thus, data will be analyzed from the first four waves only (i.e. baseline through 4th anniversary). ADS data were collected from both spouses of 634 couples, allowing this proposed study to examine the potentially important effect of partner behaviors on relationship violence. It will be important to first examine consistency with previous findings; thus, the first specific aim of this proposed study is to test a cross-sectional relation between IDU and IPV. The second specific aim is to examine the longitudinal association between husband/wife IDU and husband/wife IPV in newly married couples. The third specific aim is to test possible mediators/moderators of an IPV-IDU association, including: a) the moderation effect of partner IDU, b) the mediation effect of verbal conflict, and c) the moderation effect of hostility, avoidance coping, life stress, antisocial personality, alcohol use, and race/ethnicity. Descriptive statistics, chi-square tests, t-tests and logistic regression will be used to examine the prevalence of IDU and IPV in the sample, and to test cross-sectional relations between IDU and IPV. Multi Level Modeling will be used to test for a longitudinal relation between IDU and IPV, as well as mediation and moderation effects.
