Pathological personality traits of maladaptive daydreamers measured by the Personality Inventory for DSM-5 in a psychiatric sample.

This study aimed to estimate the frequency of maladaptive daydreaming and to explore the pathological personality traits of probable maladaptive daydreamers. Our sample consisted of 239 psychiatric patients. After screening, 42 persons were probable maladaptive, while 197 participants prove to be normal daydreamers. Two pathological domains and three facets measured by the Personality Inventory for DSM-5 showed a moderate significant correlation with the Maladaptive Daydreaming Scale. The score of nearly every domain and facet was slightly higher among probable maladaptive daydreamers. To quantify the difference between the groups, effect sizes were calculated: Significant difference was found on the domain level in Antagonism, while on the facet level in Hostility, Grandiosity, Attention Seeking, Unusual Beliefs and Experiences, Cognitive and Perceptual Dysregulation. The group of probable maladaptive daydreamers was further examined to identify potential subgroups. Cluster analysis revealed heterogeneity in the severeness and patterns of pathological personality domains. Cluster 1 showed higher mean scores on the PID domains and on the MDS compared to Cluster 2. Clusters 1 and 2 broke further down into two subclusters: Cluster 1a and Cluster 1b differed in their mean scores on the domains of Antagonism and Detachment; the mean scores of Cluster 2a were uniformly low on each domain, while the mean values of Cluster 2b were scattered in a mixed way on the domains. Our results suggest that maladaptive daydreaming might manifest with differently pathological personality profiles in the background. This aspect might worth considering in planning treatment.

[Assessment of pathological personality traits and gender characteristics by Personality Inventory for DSM-5 in a psychiatric and a normal sample].

INTRODUCTION: The DSM-5 describes two types of classification of personality disorders: a categorical and a dimensional classification. The alternative model of personality disorders in the DSM-5 determines new diagnostic criteria for personality disorders with a criterion B describing the presence of pathological personality facets. For the assessment of these domains and facets, the Personality Inventory for DSM-5 (PID-5) was created. METHODS: A sample of patients receiving psychiatric care (n=239) and a normal sample (n=226) were involved in the study. The two samples did not differ significantly regarding gender, age, and the levels of education. The PID-5 was applied to assess the pathological domains and facets. RESULTS: Psychiatric patients scored significantly higher on four out of five PID domains compared to the members of the general population. Regarding the PID facets, the two study groups differed significantly in 18 out of 25 facets. Regarding the PID domains and facets, gender differences were found in the clinical sample: Negative Affectivity was more typical for women, while Antagonism was more dominant for men. Women receiving psychiatric care were cha - rac terized by Emotional Lability and Anxiousness, while Manipulativeness, Deceitfulness, Callousness and Risk Taking were more dominant for men of the clinical sample. CONCLUSION: Our results confirmed the applicability of the dimensional personality model. The PID-5 can discriminate between psychiatric and normal samples. Our findings suggested that in the case of the general population, traditional gender characteristics disappeared, while psychiatric patients seemed to preserve the traditional gender roles.
