Replication Sample
We repeated the same analyses for the replication sample and
observed the same general results. Again, there was a positive
correlation between SPQ-BR score and Pattern Glare score (Spearman’s
rs(475) = .25, p < .001); see
Figure 5. The negative binomial regression model for the replication
sample was significant, χ2(3) = 28.54, p <.001; see
Table 2. Once again, the disorganization factor positively predicted
Pattern Glare score (b = .02, χ2 = 6.96, p < .01) and
cognitive-perceptual (p = .10) was not a significant contributor.
The one difference from the initial sample was that the interpersonal
factor now only approached significance (p = .04); see Figure 6.
The incidence rate ratio was slightly lower in the replication sample
with the disorganized factor predicting a 2% increase in the Pattern
Glare score. However, the overall finding remains consistent in which
individuals with more disorganization traits experience a greater number
of illusions in the PGT.
