Internal consistency of measures for ICD-11 personality disorder severity and traits: A systematic review and meta-analysis.

A number of measures and scales have been developed for the ICD-11 personality disorder (PD) diagnosis, including severity and trait dimensions. The present systematic review and meta-analysis sought to evaluate the internal consistency of these measures across different populations and cultures. A systematic search was conducted across four databases where relevant studies were subjected to explicit eligibility criteria resulting in 49 included studies and 370 effect sizes. Study characteristics were tabulated, their methodological quality was evaluated, and findings were synthesized using random effects meta-analysis. Findings overall indicated that measures of ICD-11 PD severity and trait domains have adequate levels of internal consistency (α/ω = 0.82, 95% CI [0.81; 0.83], I2 = 97.3%). Aspects such as sample, country, language, format, and measured construct were significant sources of variation. Additional meta-analyses revealed that some measures performed better than others for certain dimensions. Internal consistency was overall supported across ICD-11 measures of severity and trait domains. Future research should further investigate the interrater reliability, test-retest reliability and stability, and alignment with interview-based PD diagnoses.

Convergence between the dimensional PD models of ICD-11 and DSM-5: a meta-analytic approach.

In the current diagnostic systems, the International Classification of Diseases-11th rev. (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders-5th ed. (DSM-5), the evaluation and diagnosis of personality disorder (PD) aim at dimensional examination of the severity of its dysfunction and the stylistic features that accompany it. Since their implementation, or even before, several measures have been developed to assess PD severity and traits in both models. Thus, convergent validity metrics have been reported with various PD measures; however, the convergence of the same constructs included in the measures of these two models remains undefined. The objective of the present review was to examine whether there is a sufficient relationship between PD measures of the ICD-11 and DSM-5 AMPD in the general population. For this meta-analytic review, systematic searches were conducted in Web of Science, PubMed, Scopus, and Google Scholar. We included studies that reported Pearson's r correlations without restrictions on language, age, sex, setting, type of sample, or informant of the measures. We excluded associations with anankastia, psychoticism or the borderline pattern because they were not comparable between one dimensional model and the other. We examined the quality of the evidence with the JBI Critical Appraisal Checklist for Analytical Cross Sectional Studies, and performed the random effects meta-analysis with the 'meta' package of the RStudio software. Of the 5,629 results returned by the search, 16 studies were eligible; and showed moderate quality. The risk of bias was manifested by not specifying the details of the sample, the recruitment environment, and the identification and control of confounding factors. Thirteen studies provided two or more correlations resulting in a total of 54 studies for meta-analysis. The overall effect size estimate (correlation) was moderate for the overall model (r = 0.62, 95% CI [0.57, 0.67], p < 0.0001, I2 = 97.6%). For the subgroup of associations, ICD-11 severity model and DSM-5 AMPD severity model, the correlation was also moderate (k = 10, r = 0.57, 95% CI [0.48; 0.66]; I2 = 92.9%); as for the subgroup of associations, ICD-11 traits model and DSM-5 AMPD traits model (k = 44, r = 0.63, 95% CI [0.57; 0.69], I2 = 97.9%). The convergent validity between measures of PD severity and traits between one diagnostic system and another has been demonstrated in this review and they can probably be used interchangeably because they also measure the same constructs. Future research can address the limitations of this study and review the evidence for the discriminant validity of these measures.

Integrative Dimensional Personality Inventory for ICD-11: Development and Evaluation in the Peruvian Correctional Setting / Inventario Integrativo de la Personalidad Dimensional para la CIE-11: desarrollo y evaluación en el sistema penitenciario peruano

Abstract Background: Personality disorder (PD) is an important predictor of the commission of crimes; however, there is a lack of clinical instruments adjusted to the characteristics of Peruvian convicts. Objective: To develop a reliable and valid comprehensive personality measurement instrument, the Integrative Dimensional Personality Inventory, ICD-11 version (IDPI-11), according to the standards of the International Classification of Diseases (ICD-11). Method: A stratified simple of prisoners from the Huancayo Penitentiary (HP) was selected (n study 1 = 60; n study 2 = 1095). Results: High reliability indices(McDonald's _ _ .73) and adequate levels of content validity(CVI-S ≥ .87), construct validity, and criterion validity of the scales were found. This could explain the probability (a) of belonging to the group of inmates with instrumental or impulsive crimes (R2 N ≥ .52, OR ≥ 1.02, p ≤ .021), and (b) that recidivism, designated by the prison security level imposed, increases (R2≥ .53, β ≥ 1.16, p ≤ .008). Conclusions: The instrument is a valid and reliable measure that allows a dimensional and integrative assessment of the personality of convicts of the HP, according to ICD-11 standards

Resumen Antecedentes: el trastorno de la personalidad (TP) es un predictor importante en la comisión de delitos; sin embargo, existe una ausencia de instrumentos clínicos para las características del convicto peruano. Objetivo: desarrollar un instrumento de medición integral de la personalidad confiable y válido, el Inventario Integrativo de Personalidad Dimensional versión CIE-11 (IDPI-11), según los estándares de la Clasificación Internacional de Enfermedades (CIE-11). Método: se utilizó una muestra estratificada de reclusos del Establecimiento Penitenciario de Huancayo (EPH) (n estudio 1 = 60; n estudio 2 = 1095). Resultados: se encontraron altos índices de confiabilidad (ω de McDonald ≥ .73) y niveles adecuados de validez de contenido (CVI-S ≥ .87), constructo y criterio de sus escalas, pudiendo explicar la probabilidad de: (a) pertenecer al grupo de internos con delitos instrumentales o impulsivos (R2≥ .52, OR ≥ 1.02, p ≤ .021);y(b) que la tendencia a reincidir, designada por el grado de seguridad penitenciaria impuesto, aumente (R2 ≥ .53, β ≥ 1,16, p ≤ .008). Conclusiones: el instrumento construido es una medida válida y confiable que permite una evaluación dimensional e integrada de la personalidad del convicto de la EP de Huancayo, de acuerdo con los estándares de la CIE-11.
