One issue limiting the scope of use of the BAES is that, at 14 items, it may not be practical to use in research paradigms with constraints on assessment. For example, in human laboratory studies of alcohol effects, there are often multiple assessments in one session. Frequently, the BAES is administered before alcohol is consumed and then the assessment is repeated 3–4 more times after consumption to capture rising and declining BrAC limb effects. In such a design, using the full 14-item BAES would result in the participant having to complete 70 items for just this questionnaire alone. In addition, assessments during neuroimaging can be challenging, and briefer measures would enhance such research. Similarly, research that involves assessments on small handheld devices, such as ecological momentary assessments can be burdensome with lengthy measures. Although there are some cautions in using shorter assessment tools, such as the loss of variance, and a bigger impact of missing values on items, the benefits outweigh the potential costs in research paradigms that render a lengthier scale unusable.
