Joining the debate on the structure of depression, S. R. H. Bearh and N. Amir (2003) analyzed college students' responses to 6 Beck Depression Inventory (BDI) items with predominantly somatic content and concluded that they identified a small latent taxon corresponding to involuntary defeat syndrome. An exact replication of these analyses yielded virtually identical taxometric results, but parallel analyses of simulated taxonic and dimensional comparison data matching the intercorrelations and…

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.
Differentiating Categories and Dimensions: Evaluating the Robustness of Taxometric Analyses
TLDR
The impressive accuracy of the CCFI was consistent with prior findings and robust across novel manipulations of asymmetry, tail weight, and heterogeneous variances, as well as the practical implications for differentiating categories and dimensions.
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.
Categories versus dimensions in personality and psychopathology: a quantitative review of taxometric research
TLDR
It is indicated that most latent variables of interest to psychiatrists and personality and clinical psychologists are dimensional, and that many influential taxonic findings of early taxometric research are likely to be spurious.
A Taxometric Study of the Center for Epidemiological Studies Depression Scale
TLDR
Evidence of the dimensionality of CES-D indicators in a student population is consistent with a continuity view of depressive symptoms, and strategies for interpreting analyses of skewed indicators and small putative taxa are incorporated.
Latent Structure of Early Adolescent Bullying Perpetration: A Taxometric Analysis of Raw and Ranked Scores
TLDR
It was surmised that bullying perpetration is continuously organized and that rank normalized scores may improve the interpretability of taxometric findings derived from highly nonnormal indicators.
Latent structure of depression in a community sample: a taxometric analysis
TLDR
The findings of the current study suggest that depression, as measured in this subsample, is best conceptualized, measured and classified as a continuously distributed syndrome rather than as a discrete diagnostic entity.
Does a latent class underlie schizotypal personality disorder? Implications for schizophrenia.
TLDR
The possible dimensionality of schizotypal PD adds to growing support for a dimensional structure of PDs including other Cluster A disorders.

The latent structure of analogue depression: should the Beck Depression Inventory be used to classify groups?
TLDR
Analyses provided converging evidence for the dimensionality of analogue depression, arguing against the use of the BDI to classify analogue participants into groups and illustrated the notable impact of pronounced skew on taxometric results and the value of using simulated comparison data as an interpretive aid.
Categories and continua: a review of taxometric research.
TLDR
This article surveys taxometric studies of psychopathological, personality, and other variables and draws conclusions about the taxonicity of latent variables in these domains and reviews research on the validation and refinement of taxometric methods.

TLDR
Two taxometric procedures, MAMBAC and MAXCOV-HITMAX, provide independent tests of the taxonic conjecture and satisfactorily accurate estimates of theTaxon base rate, the latent means, and the valid and false-positive rates achievable by various cuts.
Taxonic Structure of Infant Reactivity: Evidence From a Taxometric Perspective
TLDR
The present research used an objective statistical procedure to determine if a qualitative latent structure, consistent with theoretical conjectures, would be found to underlie quantitative indices of reactivity to stimuli in a sample of 599 four-month-old infants and provided objective empirical support for a central tenet in the theoretical model.
Taxometric Analysis: II. Detecting Taxonicity Using Covariance of Two Quantitative Indicators in Successive Intervals of a Third Indicator (Maxcov Procedure)
TLDR
Given three quantitative indicators of a conjectured latent taxon, a statistical function defined as the covariance of two indicators computed within successive intervals along the third indicator reveals whether the latent structure of the data is taxonic or not.
Taxometric Analysis with Dichotomous Indicators: The Modified Maxcov Procedure and a Case-Removal Consistency Test
TLDR
The present investigation shows that the most widely used taxometric procedure (MAXCOV) can distinguish between latent structures when adapted for use with dichotomous indicators, although particularly large samples and substantially valid indicators are required.
Is depression taxonic, dimensional, or both?
TLDR
Examination of the potential importance of item selection in the ongoing discussion regarding the taxonicity of depression suggests that item selection is central to the determination of tax onicity in depression.
Taxometric analysis. I: Detecting taxonicity with two quantitative indicators using means above and below a sliding cut (MAMBAC procedure)
TLDR
Given two quantitative indicators of a conjectured latent taxon, a statistical function defined as the difference between the observed means for cases of one indicator falling above and below a sliding cut indicates whether the latent structure is taxonic or nontaxonic.
Informing the continuity controversy: a taxometric analysis of depression.
TLDR
Results of both studies, drawing on 3 widely used measures of depression, corroborated the dimensionality of depression and implications for the conceptualization, investigation, and assessment of depression are discussed.
