Initial construction of a maladaptive personality trait model and inventory for DSM-5
TLDR
A maladaptive personality trait model and corresponding instrument are developed as a step on the path toward helping users of DSM-5 assess traits that may or may not constitute a formal personality disorder.

TLDR
The results suggest that comorbidity results from common, underlying core psychopathological processes, and argue for focusing research on these core processes themselves, rather than on their varied manifestations as separate disorders.
Triarchic conceptualization of psychopathy: Developmental origins of disinhibition, boldness, and meanness
TLDR
Alternative historic descriptions of the disorder together with empirical findings for the best-established assessment instruments in use with adolescents and youth are reviewed as a basis for formulating an integrative, triarchic model of psychopathy.
Etiologic connections among substance dependence, antisocial behavior, and personality: modeling the externalizing spectrum.
TLDR
A hierarchical biometric model is presented of the origins of comorbidity among substance dependence, antisocial behavior, and a disinhibited personality style, and it is offered as a novel target for future research to reconcile evidence for general and specific causal factors within the externalizing spectrum.
Delineating the structure of normal and abnormal personality: an integrative hierarchical approach.
TLDR
A constructive replication approach was used to delineate an integrative hierarchical account of the structure of normal and abnormal personality, which integrates many Big Trait models proposed in the literature and provides insight into the nature of personality hierarchy more generally.
The Hierarchical Taxonomy of Psychopathology (HiTOP): A Dimensional Alternative to Traditional Nosologies
TLDR
The HiTOP promises to improve research and clinical practice by addressing the aforementioned shortcomings of traditional nosologies and provides an effective way to summarize and convey information on risk factors, etiology, pathophysiology, phenomenology, illness course, and treatment response.
Genome-wide association study identifies 74 loci associated with educational attainment
TLDR
Because educational attainment is measured in large numbers of individuals, it will continue to be useful as a proxy phenotype in efforts to characterize the genetic influences of related phenotypes, including cognition and neuropsychiatric diseases.
Factor structure of the psychopathic personality inventory: validity and implications for clinical assessment.
TLDR
A factor analysis of the subscales of the Psychopathic Personality Inventory yielded evidence for 2 factors, including positive correlations with antisocial behavior and substance abuse, negative correlations with socioeconomic status and verbal ability, and personality characteristics including high negative emotionally and low behavioral constraint.
GWAS of 126,559 Individuals Identifies Genetic Variants Associated with Educational Attainment
TLDR
Three genetic loci are found to explain variation associated with educational achievement and provide promising candidate SNPs for follow-up work, and effect size estimates can anchor power analyses in social-science genetics.
Reinterpreting comorbidity: a model-based approach to understanding and classifying psychopathology.
TLDR
A meta-analysis of a liability spectrum model of comorbidity is presented, in which specific mental disorders are understood as manifestations of latent liability factors that explain comorbridity by virtue of their impact on multiple disorders.
