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[subscript 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.
