The joint hierarchical structure of psychopathology and dysfunctional personality domain indicators among community‐dwelling adults

“…Consistent with previous findings (Faure & Forbes, 2021; Forbes et al, 2021), our data suggested that OCD features might not be homogeneously associated with the Fear system (e.g., Kotov et al, 2017; Watson, Forbes, et al, 2022). Indeed, the three BOCS scales showed positive and substantial loadings of roughly equal sized with different PCs.…”

“…Indeed, the three BOCS scales showed positive and substantial loadings of roughly equal sized with different PCs. Notably, all BOCS scales showed standardized loadings >0.40 on PC6_2; this finding was consistent with Faure and Forbes' (2021) study, which provided evidence for a close connection between OCD symptoms and the HiTOP Thought Disorder dimension. At the same time, BOCS Obsession and Severity scale scores showed substantial loadings on the Internalizing component (i.e., PC6_1; Kotov et al, 2017; Watson, Forbes, et al, 2022).…”

“…For instance, variable Cluster 1, which seemed to represent the HiTOP Thought Disorder spectrum, included also dissociative experiences. These findings are consistent with Faure and Forbes' (2021) results and may be of particular interest because the placement of dissociative experiences in the HiTOP model needs to be further clarified (e.g., Kotov et al, 2020). The secondary loadings on our PC6_1 of the dissociation scales were not unexpected, because they loaded mainly on the same component at level four of the hierarchy (see Table S28).…”

“…Indeed, confirming and extending Forbes et al's (2021) findings, our variable Cluster 1 seemed to represent the Thought Disorder spectrum of the HiTOP model. Thus, according to our findings, at syndrome level, the HiTOP Thought Disorder spectrum is likely to include not only psychotic positive and prodromal symptoms but also obsessive-compulsive symptoms (Faure & Forbes, 2021;Forbes et al, 2021) and dissociative experiences, while being rooted in the DSM-5 AMPD Psychoticism dysfunctional personality domain.…”

The Placement of Obsessive-Compulsive Symptoms Within a Five-Factor Model of Maladaptive Personality

“…Based on studies of both the clinical phenomenology and personality correlates of OCD, as well as structural analyses of OC symptoms in relation to higher-order psychopathology structure (Faure & Forbes, 2021;Sellbom et al, 2020), we hypothesize that a five-factor solution will yield factors that are recognizable as the PID-5 trait domains and that OC symptoms will most strongly cross-load on the Negative Affect and Psychoticism PID-5 factors. Further, we hypothesize that the OCI-R total score will negatively load on the Disinhibition factor due to the placement of Rigid Perfectionism on the low end of this factor.…”
