Fig 2 — Hierarchical solutions with standardized factor loadings, residual variances and covariances. 2A: second-order model (Model 4); 2B: orthogonal bifactor model (Model 5). Int = Internalizing; Ext = Externalizing; Dpr = Depression; Anx = Anxiety; Agg = Aggression; Psy = Psychopathy; Alc = Alcohol use; Trt = Trait anger; Bdym = Body image; Etn = Eating attitudes; Sxl = Sexual distress. Rectangles represent manifest variables, circles represent latent variables. Residual variances of the manifest and first-order latent variables are reported on curved lines with double-headed arrows. The residual variance of the “P” factor was set to unity and is not reported here. Straight lines with double-headed arrows connecting the residuals of two variables indicate non-causal associations. Factor loadings are reported on straight lines with single-headed arrows, manifest and first-order latent variables are at the head of arrow.
