Materials and Methods: The S-VAAQ is a 9-item screening tool adapted from the three core domains of gaming disorder outlined in ICD-11: impaired control over usage, increased priority given to gaming, and continued use despite negative consequences. Items were modified to better reflect short-form video consumption behaviors. Data were collected through an online questionnaire distributed via short-form video platforms and Line, targeting Thai participants aged 13 and above who regularly watched short-form videos and were proficient in Thai. Statistical analyses included content validity index (CVI) assessments by five experts, Cronbach’s alpha for internal consistency, and exploratory factor analysis (EFA). Results: A total of 1,932 participants aged 13 years and older were included. The median daily duration of short-form video viewing was three hours. All items demonstrated CVI scores exceeding 0.78. The scale exhibited good internal consistency, with a Cronbach’s alpha of 0.884. KMO Measure of Sampling Adequacy of 0.898 and EFA revealed factor loadings ranging from 0.594 to 0.904 supporting the scale’s construct validity. Conclusions: In conclusion, the S-VAAQ demonstrated good reliability and validity. This instrument can serve as a useful tool for screening short-form video addiction in the Thai population and support further research and intervention strategies.MedicineArticleSCOPUS10.33192/smj.v78i2.2785502-s2.0-10503258324022288082
