What does a low score on the One-Leg Stand test suggest?

A low score on the One-Leg Stand test indicates that the subject is likely experiencing a higher level of impairment. The One-Leg Stand is a physical coordination test used to assess a person's balance and ability to perform tasks while under potential influence. During this test, an individual is required to stand on one leg while counting aloud, which demands both balance and cognitive control.

When someone is under the influence of alcohol or other substances, their physical coordination and cognitive functioning can be significantly affected, resulting in difficulty maintaining balance or following instructions. A low score on this test is thus a strong indicator of impairment due to these effects, as it showcases their reduced ability to perform a simple task that requires both physical and mental faculties.

The other options do not correlate as directly with the implications of the One-Leg Stand test. For example, while prescription medication can impair an individual, not all low scores are related to prescribed substances; similarly, anxiety may influence performance but is not as directly related as a clear indicator of impairment. Lastly, exhibiting confidence would not logically lead to a low score, as confidence typically suggests ease or proficiency in task completion.
