title: Dimensional structure and measurement invariance of the youth self-report across gender and age.
abstract: OBJECTIVE
  The aim of the present work was to examine the correlated eight-syndrome model of the Youth Self-Report (YSR) proposed by Ivanova et al [1], using a confirmatory factor analysis for ordinal data. Likewise, we explored the measurement invariance of the YSR across gender and age using multigroup comparisons, and checked whether there were differences in the latent means.
  
  
  METHODS
  The sample was made up of 4,868 nonclinical adolescents (47.6% males), with a mean age of 14.6 years (SD = 1.6).
  
  
  RESULTS
  The correlated eight-syndrome model proposed by Ivanova et al [1] showed a reasonable fit to the data, both for the total sample and by participants' gender and age. Moreover, the factor-equivalence analysis showed that the hypothesized dimensional model was invariant across gender and age. Statistically significant differences were found when comparing latent means between the groups.
  
  
  CONCLUSIONS
  These results coincide with those found in the literature and are in support of the replicability, generalizability, and consistency of the eight-syndrome model of the YSR, as well as its measurement invariance across gender and age. Future studies should explore the measurement invariance of this model through multigroup comparisons across cultures.
