Objectives: The present normative study aimed to (1) develop the Italian version of the Starkstein Apathy Scale (SAS-I) and (2) construct a shortened version including only the most sensitive items to “pure apathy” experiences. Methods: The normative sample included 392 healthy subjects. A regression-based procedure was used to explore the effects of sex, age, and education on the raw SAS-I score. A correction grid was designed for adjusting raw scores by adding or subtracting the contribution of any significant variable and net of sociodemographic interindividual differences. Cutoff scores were also calculated and fixed at the external tolerance limit on the ninety-fifth centile. To obtain the shortened version, each SAS-I item was correlated with the Beck’s Depression Inventory (BDI) score. The only items showing no correlation with BDI were implemented to bypass the well-known overlap between apathetic and depressive symptoms. Results: The mean raw SAS-I score was 11.27 (SD = 4.42). A significant education effect was observed, with highly educated subjects obtaining lower scores than lowly educated ones. The proposed general cutoff score was 20.68. The SAS-I had fair internal consistency and discriminant validity. Internal consistency increased by removing item 3. The new SAS-6 included items 1, 2, 4, 10, 11, and 13 of the original scale. Conclusion: The SAS-I is a reliable assessment tool to support the diagnosis of apathy. The SAS-6, instead, is a brief questionnaire useful for quickly screening apathetic symptoms in outpatient practice, addressing or not the clinician to further investigations.
