Structural validity

Structural validity refers to how well a test or questionnaire accurately measures the underlying concept it intends to assess. It evaluates whether the way questions are organized and grouped reflects the real structure of the concept. For example, if a survey aims to measure anxiety, structural validity checks if different questions about physical symptoms, thoughts, and feelings naturally cluster into those specific areas, matching the concept's true structure. Essentially, it's about ensuring the test's design aligns with the real-world organization of what it's trying to measure, so results are accurate and meaningful.
