- 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.
- 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).
- Depression
and Impulsiveness
are correlated antecedents of Self-esteem.
- A path diagram of the model is shown below.
