Taxometric research methods were developed by Paul Meehl and colleagues to distinguish between categorical and dimensional models of latent variables. We have conducted a comprehensive review of published taxometric research that included 177 articles, 311 distinct findings and a combined sample of 533 377 participants. Multilevel logistic regression analyses have examined the methodological and substantive variables associated with taxonic (categorical) findings. Although 38.9% of findings… 
Dimensions over categories: a meta-analysis of taxometric research
TLDR
The meta-analytic findings support the conclusion that the great majority of psychological differences between people are latently continuous, and that psychopathology is no exception.

Objective The default assumption among most psychologists is that personality varies along a set of underlying dimensions, but belief in the existence of discrete personality types persists in some
DSM-IV antisocial personality disorder and conduct disorder: evidence for taxonic structures among individuals with and without substance use disorders in the general population.
TLDR
That the structure of ASPD and CD may be taxonic suggests that further research on these disorders use group comparative designs in which samples with and without these disorders are compared in terms of sociodemographic and clinical correlates, comorbidity, and treatment utilization.
Kinds versus continua: a review of psychometric approaches to uncover the structure of psychiatric constructs
TLDR
The evaluation of the psychometric literature shows that the kinds–continua distinction is considerably more subtle than is often presupposed in research; in particular, the hypotheses of kinds and continua are not mutually exclusive or exhaustive.
DSM-IV schizotypal personality disorder: a taxometric analysis among individuals with and without substance use disorders in the general population.
TLDR
Taxometric research on SPD and other personality psychopathology among high risk subgroups of the population can help elucidate the complex etiology of SPD and the role played by comorbid substance use disorders in the expressivity of these disorders.
Dimensionality vs taxonicity of schizotypy: some new data and challenges ahead.
TLDR
Comparing inconsistencies in the literature is reconciled by discussing threats to the validity of this and similar research on Meehl's taxonomic model of schizotypy, including conceptual limitations of the lexical hypothesis and conventions of factor analysis.
A Hierarchical Integration of Normal and Abnormal Personality Dimensions: Structure and Predictive Validity in a Heterogeneous Sample of Psychiatric Outpatients
TLDR
Targeted factor analysis is used to integrate the 25 maladaptive facet-level traits of the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorder–Fifth edition and the 10 aspect-level Traits of the normal personality hierarchy within a sample of 198 psychiatric outpatients, suggesting that research on the development, causes, and structure of lower-order traits within thenormal personality hierarchy may serve as an important guide to research onThe causes andructure of maladaptives personality.
Are Negative Symptoms Dimensional or Categorical? Detection and Validation of Deficit Schizophrenia With Taxometric and Latent Variable Mixture Models.
TLDR
Although a categorical approach is validated, a hybrid categorical-dimensional conceptualization of negative symptoms also has validity for the prediction of external variables.
Integrating Structure and Function in Conceptualizing and Assessing Pathological Traits
TLDR
It is suggested that between-person structure identifies the principal domains of functioning, but to understand dysfunction personality must be conceptualized and studied as an ensemble of contextualized dynamic processes.

Paranoid personality has a dimensional latent structure: taxometric analyses of community and clinical samples.
TLDR
Analyses across both self-report and interview-based indicators offered compelling support for a dimensional structure, and analyses of external correlates in these data sets suggested that dimensional models demonstrated stronger validity coefficients with criterion measures than did dichotomous models.
Taxometric evidence for the dimensional structure of cluster-C, paranoid, and borderline personality disorders.
TLDR
This work investigated the latent structure underlying Avoidant, Dependent, Obsessive-Compulsive, Depressive, Paranoid, and Borderline PD by means of three types of taxometric analyses, finding greater evidence for a latent dimensional structure.
Diagnosing Major Depressive Disorder XI: A Taxometric Investigation of the Structure Underlying DSM-IV Symptoms
TLDR
The results of a series of taxometric procedures and consistency tests supported a taxonic structural model, consistent with the only previous taxometric study of DSM-IV symptoms in an adult outpatient sample, and have implications for the assessment and diagnosis of major depressive disorder.
A taxometric analysis of the latent structure of psychopathy: evidence for dimensionality.
TLDR
Recent advances in taxometric analysis were added to P. Meehl's (1995) multiple consistency tests strategy for assessing taxonicity, and they indicated that both the individual components of psychopathy and their interface are distributed dimensionally.
Is antisocial personality disorder continuous or categorical? A taxometric analysis
TLDR
Evidence that ASPD is dimensional suggests that it is best studied using continuous measures and that dichotomizing individuals into ASPD versus non-ASPD groups will typically result in decreased statistical power.
A Taxometric Investigation of DSM-IV Major Depression in a Large Outpatient Sample
TLDR
The present study examined the latent structure of MDD using indicator sets constructed from a semistructured clinical interview, self-report questionnaires, and a combination of the two, finding results suggestive of taxonic structure.
TAXOMETRIC ANALYSIS OF BORDERLINE PERSONALITY DISORDER by KARI
Controversy persists regarding the dimensional or categorical nature of personality disorders. The distinctness of Borderline Personality Disorder (BPD) as a discrete mental disorder has been
Assessment and diagnosis of personality disorder: perennial issues and an emerging reconceptualization.
  • L. Clark
  • Psychology
    Annual review of psychology
  • 2007
TLDR
This chapter reviews recent personality disorder research, focusing on three major domains: assessment, comorbidity, and stability, and finds a new model for assessing PD-and perhaps all psychopathology-emerges from integrating these interrelated reconceptualizations.
Contrasting prototypes and dimensions in the classification of personality pathology: evidence that dimensions, but not prototypes, are robust
TLDR
Factor analysis revealed that the dimensional structures underlying specific traits were highly robust across samples, and was interpreted as further evidence of the fundamentally dimensional nature of an empirically based classification of personality pathology.
