DESCRIPTION (provided by applicant): We believe that alcohol use is related to the increase in frequency and severity of IPV through a process of over-arousal resulting from the cortically and psycho physiological arousing effects of alcohol during the ascending limb of intoxication and at peak BAC compounded by the unique behavioral and affective patterns of violent couples. We hypothesize that distressed violent (DV) partners will have greater difficulty regulating emotion in response to evocative partner stimuli under the influence of alcohol compared to distressed nonviolent (DNV) partners. As such, this study will utilize electroencephalography (EEG), psychophysiology and pupillary response measures to investigate the effects of alcohol on the ability to regulate emotional arousal when viewing evocative partner stimuli in distressed violent (DV) partners compared to distressed nonviolent (DNV) partners. One partner from each DV couple will be pseudo-randomly selected and yoked to a DNV partner of the same sex and comparable relationship distress for participation in the experiment. To test the overall hypothesis that over-arousal is a mechanism through which alcohol is associated with increases in the frequency and severity of IPV, the selected partners will participate in a counter-balanced placebo session and alcohol administration session during which EEG, psychophysiology and pupillary response measurements of arousal will be collected during an emotion regulation task. The study is comprised of one Stimuli Acquisition Session and two Emotion-Regulation Sessions. During the Stimuli Acquisition Session, partner stimuli for use in the emotion-regulation task will be acquired through a video-taped discussion of a disagreement via the researcher facilitated Couple's Problem Inventory (CPI). Segments of the videos will be selected where the DV and DNV partners display Contempt, Belligerence, Criticism, and Defensiveness, Stonewalling and neutral behaviors for presentation to the partner during the emotion regulation task. The selected partners (DV, DNV) will return to the laboratory on two separate occasions for the completion of the Emotion-Regulation Sessions of the study. Participants will consume either an alcohol beverage or placebo beverage (counter-balanced alcohol and placebo conditions) and complete the emotion-regulation task during which evocative and neutral stimulus clips will be shown. The data will be analyzed using repeated measures ANOVA with a between-subjects factor. We expect that DV partners will experience significantly greater arousal than DNV partners during evocative stimuli. We also expect that DV partners will experience greater difficulty regulating emotion during evocative stimuli than DNV partners and that this effect will be compounded during alcohol administration. Findings from this study will provide firm evidence that alcohol is associated with IPV a mechanism of over-arousal. Furthermore, these are processes that are amenable to novel therapeutic intervention via methods such as biofeedback and neurofeedback to increase behavioral flexibility and reduce drinking and IPV in DV couples.

描述（由申请人提供）：我们认为，饮酒与IPV的频率和严重程度的增加有关，这是由于在中毒的上升和峰值BAC时，酒精的皮质和心理生理唤起效应导致的过度散发性，并由独特的行为行为和情感模式的猛烈的猛烈伴侣。我们假设与苦恼的非暴力（DNV）伴侣相比，在酒精的影响下，遇到的暴力（DV）伴侣在调节情绪方面将有更大的困难。因此，这项研究将利用脑电图（EEG），心理生理学和瞳孔反应措施来研究酒精对与苦恼的非暴力（DNV）伴侣相比，观察令人沮丧的暴力伴侣（DV）伴侣中的令人回味的伴侣刺激的能力。每位DV夫妇的一个合作伙伴将被选为伪随机，并将其与同性性别和可比关系困扰的DNV合作伙伴一起参加实验。为了检验过度疗程的总体假设是一种机制，酒精与IPV的频率和严重程度的增加相关，选定的伴侣将参加反平衡的安慰剂会议和酒精给药课程，在此期间，在情绪调节任务期间，将收集EEG，心理生理学和瞳孔应答测量值。该研究包括一次刺激性习得和两个情绪调节会议。在刺激性获取会议中，将通过视频绘制的讨论通过研究人员促进夫妇的问题清单（CPI）来获取用于情绪调节任务的伴侣刺激。将选择视频的细分市场，在情绪调节任务期间，DV和DNV合作伙伴表现出蔑视，好战，批评和防御性，石墙和中性行为。选定的合作伙伴（DV，DNV）将两次分别返回实验室，以完成该研究的情绪调节课程。参与者将消费酒精饮料或安慰剂饮料（抗酒精和安慰剂条件），并完成情绪调节任务，在此任务中将显示令人回味和中性的刺激片段。将使用带有受试者间因子的重复测量方差分析对数据进行分析。我们预计，在回忆性刺激期间，DV伴侣会比DNV伴侣出现明显更大的唤醒。我们还希望，与DNV伴侣相比，DV伴侣在调节刺激过程中调节情绪的困难会更大，并且在饮酒期间，这种效果将变得更加复杂。这项研究的发现将提供牢固的证据，表明酒精与IPV相关的一种过度的机制。此外，这些过程是通过诸如生物反馈和神经反馈等方法来提高行为灵活性并减少DV夫妇中的饮酒和IPV等方法的新型治疗干预过程。
