D  Data
  • The data set contains 204 observations of 12 continuous variables.
  • The 12 variables are indicators of the latent variables Self-esteem, Depression and Impulsiveness.
  • The 12 variables are observed on a 5-point Likert scale.
  • The data set is listed in the file DEPRESS.PSF.
  • DEPRESS.PSF is located in the TUTORIAL folder.
  • The first portion of DEPRESS.PSF is shown in the PSF window below.

M  Model
  • SELF1 to SELF5 are indicators of the latent variable Self-esteem (selfest).
  • DEPRES1 to DEPRES4 are indicators of the latent variable Depression (depress).
  • IMPULS1 to IMPULS3 are indicators of the latent variable Impulsiveness (impuls).
  • A path diagram for the corresponding measurement model is shown below.
