- 神经科学是一个神经科学.
- 行为科学 行为科学
背景情况:
- 酒精使用障碍 (AUD) 经常与退伍军人的其他精神疾病同时发生.
- 靠近回避训练 (AAT) 是一种计算机交付的认知偏差修改,通过准隐性方法偏差来治疗AUD,显示出有前途.
- 作为AUD的辅助治疗,AAT在患有并发性精神疾病的退伍军人中的有效性需要进一步调查.
研究的目的:
- 评估AAT作为AUD的辅助治疗在接受标准门诊护理的退伍军人的有效性.
- 评估AAT对AUD恢复结果的影响,包括饮酒和酒精消费的功能后果.
- 使用fMRI检查AAT对酒精方法偏差和神经反应的行为指标的影响.
主要方法:
- 一个双盲随机对照试验,涉及136名退伍军人患有AUD和并发性精神疾病.
- 参与者将随机分配到接受6周的AAT或Sham条件,以及通常的护理.
- 评估将在基线,6周,3个月和6个月进行,其中一个子组接受fMRI.

Blind Procedures
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...
Introduction to Test of Independence
In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

Randomized Experiments
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Blinding
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
