This study examined the psychometric properties of the Chinese version of the Social-Emotional Assessment Measure (SEAM) (33–66 months), which is designed to assess social-emotional difficulties and behavior disorders in young children. In this case, the SEAM was translated and back-translated. The sample included 2477 preschoolers (1256 boys; M age = 57.57 months, SD = 10.93) residing in Shanghai, China. In summary, the results presented a 10-factor model that showed a good fit for the SEAM (33–66 months). Ultimately, the analyses demonstrated adequate internal consistency, reliability, and convergent validity. These findings indicate that the SEAM (33–36 months) is appropriate for use in Chinese preschool populations.
