Best practice recommendations for scale construction in organizational research: The development and initial validation of the Character Strength Inventory (CSI)

Proper scale development and validation provide the necessary foundation to facilitate future quantitative research in the organizational sciences. Using the framework provided by the Researcher's Notebook, the purpose of this study is twofold. First, we present a modern summary of best practice procedures for scale development, reliability analysis, and validity analysis. Second, we explain and illustrate these best practice procedures by describing each procedure in the context of developing and psychometrically analyzing a new Character Strength Inventory (CSI).
