# Internal Structure Validation

> - Use when examining the internal structure of a selection procedure as supporting validity evidence — the relationships among items/components and how they conform to the intended conceptual framework (unidimensional vs. multidimensional). Covers dimensionality, factor-analytic models, when coefficient alpha is and isn't appropriate, and validity of subscores. Triggers: "internal structure", "dimensionality", "factor analysis / CFA", "coefficient alpha", "is this scale unidimensional", "subscale validity".
