This research demonstrates the psychometric properties of the Sarcastic Critical Humor Inventory in university students, indicating effective reliability and validity measures.
The objective of the research was to develop and determine the psychometric properties of the Sarcastic Critical Humor Inventory (IHCD-25) in university students from the city of Trujillo. A psychometric methodology with an instrumental, non-experimental, and cross-sectional design was used, with a non-probabilistic convenience sampling of 400 students, divided into two groups for exploratory and confirmatory factor analyses. Content validity was established through expert judgment, obtaining an Aiken's V coefficient of 1.00 for all items. Construct validity was determined through exploratory and confirmatory factor analyses, yielding fit indices of CFI=0.908, TLI=0.901, RMSEA=0.075, and SRMR=0.051. Additionally, the overall reliability of the instrument was determined using the Omega coefficient, with a value of 0.978. Finally, percentile norms were established for score interpretation. It was concluded that the inventory demonstrated adequate psychometric properties.
