The 5-item version of Collective Narcissism Scale has been used in different cultural and national contexts and has persistently shown excellent concurrent and predictive validity (Golec de Zavala, Dyduch-Hazar, & Lantos, 2019). We aimed at shortening the scale from five to three items by conducting IRT analyses on Polish, German and Turkish sample.
Suggested items for the ultra-short version of Collective Narcissism Scale
- 1. My group deserves special treatment.
- 2. Not many people seem to fully understand the importance of my group.
- 3. I will ever be satisfied until my group gets the recognition it deserves.
The complete analysis following item response theory approach are reported here.
