What is a common limitation of rating scales using numbers or general descriptive adjectives?

Lack of clarity in trait definition

The correct answer is Option 2:Lack of clarity in trait definition

A common limitation of rating scales using numbers or general descriptive adjectives is the lack of clarity in trait definition. The NCERT explains that personality is often described using general terms like “shy”, “friendly”, “warm”, etc., which are broad and not precisely defined . When such vague adjectives or numbers are used in rating scales, they do not clearly specify what each level or trait actually means. As a result, different raters may interpret them differently, leading to inconsistency. Hence, the core limitation is unclear definition of traits.

Why other options are incorrect

• Option (1) Raters’ biases: Bias can occur in any evaluation method, but it is not specific to rating scales using numbers or adjectives. It is a general human limitation, not the main issue with this type of scale.
• Option (3) Confusion for the rater: Confusion may arise, but it is a result of unclear trait definitions, not the root problem. The fundamental limitation lies in the vagueness of the scale itself.
• Option (4) Inadequate training for raters: This is an administrative issue. Even well-trained raters can interpret vague adjectives differently if the scale lacks clear definitions.
