When were the scales normed? Are there plans to re-norm any time soon?

ASEBA scores have shown little change for population samples obtained in different decades in the U.S. (T. Achenbach et al., School Psychology Review, 2002, 428-442; Journal of Emotional and Behavioral Disorders, 2002, 194-303; Journal of Abnormal Child Psychology, 2003, 1-11); Holland (N. Tick et al., Acta Psychiatric Scandinavica, 2007, 473-483; Social Psychiatry and Psychiatric Epidemiology, 2008, 349-355; Journal of the American Academy of Child and Adolescent Psychiatry, 2007, 1333-1340); Norway (Jozefiak et al., Nordic Journal of Psychiatry, 2012, 311-319); Japan (M. Kawauchi et al, Psychiatrica et Neurologia Paediatrica Japonica, 2011, 143-155); and Denmark (J. Henriksen et al., Danish Medical Journal, 2012, A4462).

The stability of ASEBA scores over decades for population samples from multiple countries suggests that it would not be cost-effective to spend millions of dollars obtaining a new U.S. normative sample so soon after the last one. Instead, we are continuing to obtain data for population samples from additional countries for inclusion in ASEBA’s multicultural norms for ages 1½-59 years, as reported at https://aseba.org/societies/.
