简要总结
The research study seeks to refine and test a brief, self-directed, intervention for individuals from the general public with PTSD and co-occurring HD that can be delivered via text-messaging. This application seeks to refine the intervention further by testing whether theoretically-driven, evidence-based strategies from basic cognitive psychology (message framing) and social psychology (facilitating growth mindsets) result in better outcomes for PTSD symptoms and HD by addressing pilot participant feedback related to avoidance and motivation.
详细描述
This study will refine a previously piloted text message intervention by integrating and testing the efficacy of behavioral nudge and psychologically-wise intervention techniques when added to CBT text messages for reducing hazardous drinking (HD) and PTSD symptoms.The enhancements will be tested in a fully crossed 3 (message framing: avoid losses vs. maximize gains vs. no framing) x 2 (mindsets: facilitate growth mindset reminder vs. simple reminder to use skills) factorial design to identify the most effective combination of text messages. A sample of 500 participants with DSM-5 Criterion A trauma exposure, PTSD symptoms, and HD will be enrolled and randomized to condition. Baseline, immediate post-, 1-, and 3-month assessments will capture change in primary outcomes (PTSD, hazardous drinking).
Trauma exposure and PTSD symptoms will be assessed using the Posttraumatic Stress Disorder Checklist, Civilian Version DSM-5 with the Life Events Checklist (PCL-5 and LEC).
HD will be assessed via a set of measures that provide a detailed picture of drinking patterns. First, two questions will ask about heavy episodic drinking (HED: 4/5 or more drinks per single occasion for men/women) episodes, assessing both frequency over the lifetime and frequency over the last month. Typical weekly alcohol consumption will also be assessed using the Daily Drinking Questionnaire (DDQ). Negative alcohol-related consequences will be assessed via the Short Index of Problems (SIP).

研究组 & 干预措施
Loss Framing + Growth Mindset
Participants in this condition will receive 3 days of text messages for 4 weeks. Day 1 will consist of psychoeducation about CBT skill, day 2 will be a remainder to use the skill that is framed with toward preventing future losses from trauma exposure, and day 3 will have a reminder that aims to instill a growth mindset about using the skill.

结局指标
主要结局
Heavy Episodic Drinking
时间窗: Baseline, 4 weeks, 8 weeks, 16 weeks
Heavy Episodic Drinking (HED) assesses the quantity of heavy drinking episodes (i.e., \>4/5 drinks per occasion for women/men, based on the National Institute of Alcohol Abuse and Alcoholism's definition) over the last month. It is administered at pre-intervention (baseline), post-intervention (week 4), 1 month follow up (week 8), and 3 month follow up (week 16). The range of the scale is 0-10 (count of the number of heavy drinking episodes in the last month); 10 is described as 10 or more heavy drinking episodes. Higher scores represent a greater number of heavy drinking episodes.
Posttraumatic Stress Disorder (PTSD)
时间窗: Baseline, 4 weeks, 8 weeks, and 16 weeks
The Posttraumatic Stress Disorder Checklist for the 5th Edition of Diagnostic and Statistical Manual of Mental Disorders (PCL-5) assesses the severity of symptoms of posttraumatic stress disorder (PTSD) as defined by the 5th Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and is administered at pre-intervention (baseline), post-intervention (week 4), 1 month follow up (week 8), and 3 month follow up (week 16) to assess change in PTSD symptoms. The range of the scale is 0-80. Higher scores represent more severe PTSD symptoms.
Typical Weekly Alcohol Consumption
时间窗: Baseline, 4 weeks, 8 weeks, 16 weeks
The Daily Drinking Questionnaire (DDQ) assesses the number of standard drinks consumed each day of a typical week over the last month and is administered at pre-intervention (baseline), post-intervention (week 4), 1 month follow up (week 8), and 3 month follow up (week 16). The range for the scale to report drinks consumed each day is 0-25. Each day's score for the week is summed to created a total number of drinks consumed per week; the count of drinks consumed per week ranges from 0 to 175. Higher scores representing greater number of drinks consumed during a typical week.
Alcohol Use Consequences
时间窗: Baseline, 4 weeks, 8 weeks, 16 weeks
The Short Index of Problems (SIP) assesses the negative consequences from alcohol consumption over the last month and is administered at pre-intervention (baseline), post-intervention (week 4), 1 month follow up (week 8), and 3 month follow up (week 16). The range for the scale is 0-15 and higher scores represent a greater number of alcohol-related consequences.
