A sample suffers range restriction (RR) when its variance is reduced comparing with its population variance and, in turn, it fails representing such population. If the RR occurs over the latent factor, not directly over the observed variable, the researcher deals with an indirect RR, common when using convenience samples. This work explores how…

The problem of demonstrating replicability of factor structure across random variables is addressed. Procedures are outlined which combine the use of random subsample replication strategies with the correlations between factor score estimates across replicate pairs to generate a coefficient of replicability and confidence intervals associated with…

This study tests the degree of factor invariance and factor structure replicability of the Family Environment Interview Schedule. Samples of families from different locations were used. Four interpretable factors were derived. Evidence suggests that the four factor solution was invariant across both samples with an identical factor structure.…
