Confirmatory Factor Analysis of the Inventory of Personality Organization-Reality Testing Subscale

Blog Article

The reality supreme hysteric glamour text testing dimension of the Inventory of Personality Organization, the IPO-RT, has emerged as an important index of proneness to reality testing deficits.However, to date few studies have examined the factorial structure of the IPO-RT in isolation.This is an important and necessary development because studies use the IPO-RT as a discrete measure.Additionally, psychometric evaluation of the IPO suggests alternative factorial solutions.Specifically, recent work supports multidimensionality, whereas initial IPO assessment evinced a unidimensional structure.

Accordingly, this study, using a heterogeneous sample (N = 652), tested the fit of several factorial models (one-factor, four-factor oblique, second-order, and bifactor) via maximum likelihood with bootstrapping due to multivariate non-normality.Analysis revealed superior fit for the bifactor solution (correlated errors) (CFI = 0.965, SRMR = 0.036, RMSEA = 0.042).

This model comprised a general reality testing dimension alongside four subfactors (auditory and visual hallucinations, delusional thinking, social deficits, and confusion).Inter-factor correlations were in the moderate range.Item loadings and omega reliability supported the notion that outil pour bague de verrouillage bosch the IPO-RT emphasizes a single latent construct.The model demonstrated invariance across gender and partial age invariance.Overall, from a psychometric perspective, the IPO-RT functioned effectively at both global and, to an extent, factorial levels.

Findings recommend that the IPO-RT should be scored as a total scale, and rather than treat subscales independently, future studies should consider examining factor variance alongside overall scale scores.
