Quizplus · Accepted Answer

The Bleemness scale only consists of one item, which asks a vague and subjective question. Therefore, the scale lacks construct validity, as it doesn't measure what it claims to measure. It also lacks internal validity because other variables that could contribute to the respondent's answer, such as their mood or environment, are not controlled. There are no clear criteria to measure Bleemness, so criterion validity is not applicable. Face validity deals with how well the scale appears to measure what it intends to measure, and this could be argued since the item explicitly asks about Bleemness. However, this is not a very strong form of validity, and it's not enough to compensate for the scale's lack of construct and internal validity.
