简要总结
The purpose of the study "Stress, Emotion Regulation, and Alcohol in Women Veterans" is to learn about the effects of negative emotion and stress on behavior (including alcohol use) among women Veterans, including women with and without posttraumatic stress disorder. Additionally, the study looks at whether a woman's use of emotion regulation techniques changes the association between stress or negative emotion and behavior. Lastly, the study examines how women's reactions to stress, and the effects of stress, vary across the menstrual cycle - depending on the level of circulating hormones.
详细描述
Aims for the current study are two-fold: 1. conduct a randomized trial testing the effects of an emotion regulation skill (cognitive reappraisal) on stress-induced drinking among women with alcohol misuse and varying levels of co-occurring PTSD; 2. examine whether progesterone levels and/or severity of co-occurring PTSD - factors which impact women's stress reactivity and emotion regulation - moderate the effectiveness of the cognitive reappraisal in reducing stress-induced drinking.
The proposed study will combine experimental, in-person sessions with daily self-report data from the Veterans to assess the effect of cognitive reappraisal on alcohol craving, cognitive (inhibitory) control, physiological arousal (HRV), and alcohol use. Participation will take place across a period of at least 35 days, to encompass an entire menstrual cycle. All participants complete all sections of the study - the experimental sessions and the longitudinal (35-day) data collection.

结局指标
主要结局
Change in frequency of alcohol use prior to and through study completion
时间窗: Retrospectively for 45 days prior to study enrollment, and through study completion (up to 75 days post-baseline)
The Alcohol Timeline Follow Back (TLFB) assesses frequency/quantity of drinking. The TLFB will be used at all laboratory sessions to fill in any potentially missing data from the daily logs
Change in Alcohol Craving during Experimental Sessions
时间窗: Two separate days during the study (ie. on two of the study days, which last up to 75 days)
Craving will be measured via the Alcohol Craving Questionnaire - Short Form (ACQ-SF). The ACQ-SF comprises 12 items and is used to assess alcohol cravings among alcohol users in the current moment. Participants are asked to rate how much they agree or disagree with each statement, each regarding how they feel or think about alcohol in the moment. Each item is scored on a 7-point Likert scale that reflects their agreement on a scale of "strongly disagree" to "strongly agree".
Change in Inhibitory Control during Experimental Sessions
时间窗: Two separate days during the study (ie. on two of the study days, which last up to 75 days)
Inhibitory Control, a measure of behavioral impulsivity, will be assessed with a computerized task (a stop-signal task, STOP-IT). Participants' stop signal reaction time (SSRT) reflects varying levels of inhibitory control (lower SSRT reflects better inhibitory control).
Change in Heart Rate Variability (HRV) during Experimental Sessions
时间窗: Two separate days during the study (ie. on two of the study days, which last up to 75 days)
Heart rate variability (HRV), a physiological measure of arousal and shown to be a measure of stress reactivity and impacted by successful emotion regulation, will be assessed with a Biopac MP160 data acquisition unit with an ECG amplifier that allows for the measurement of HRV.
次要结局
- Change in intensity of daily negative affect(Daily, through study completion (up to 75 days post-baseline))
- Change in depression symptoms from baseline to study completion, un to 75 days(Baseline, end of study (up to 75 days))
- Change in use of adaptive and maladaptive emotion regulation strategies(weekly, through study completion (up to 75 days post-baseline))
