概要	Short-form content validity evaluates whether items retained in an abbreviated scale still adequately represent every substantive facet of the construct measured by the original full-length instrument. It ensures that shortening a scale does not hollow out the conceptual domain it was designed to cover.	Short-form item analysis is the systematic psychometric evaluation and selection of items when constructing an abbreviated version of a longer measurement instrument. It applies classical and modern item-analysis criteria — item-total correlations, reliability estimates, and factor structure — to identify the smallest item subset that preserves the original scale's psychometric integrity.
