Integrative Dimensional Personality Inventory for ICD-11: Development and Evaluation in the Peruvian Correctional Setting

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 sample of prisoners from the Huancayo Penitentiary (HP) was selected (n study 1 = 60; n study 2 = 1095). Results: High reliability indices (McDonald’s ω ≥ .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.

Diagnostic accuracy of severity measures of ICD-11 and DSM-5 personality disorder: clarifying the clinical landscape with the most up-to-date evidence

“…The first measure developed was the Standardized Assessment of Severity of Personality Disorder (SASPD; 16 ) which was designed even before the final version of the guidelines was published. Other recent measures include the ICD-11 Personality Disorder Severity Scale (PDS-ICD-11; 17 ), Clark et al scales ( 18 ), and PF scale of the Integrative Dimensional Personality Inventory for ICD-11 (IDPI-11; 19 ). Unlike criterion A of the DSM-5 AMPD, these measures have a unifactorial nature since self and interpersonal functioning are defined in a more interconnected way and linked to real-life consequences at moderate to severe levels, such as self-harm or harm to others and the reality test ( 20 ).…”

Cultural lenses of the utility of the ICD-11-PD model: Integrating the Peruvian context

“…In addition to the roles mentioned, Table 1 provides a general description of the cultural aspects of PD according to ICD-11. Since the ICD-11 PD model, only one study has been carried out on male inmates in a prison in the Peruvian highlands, mainly finding differences according to the age of the participants and the crime committed, since the general psychopathology included in PD is more common in those under 35 years of age and in crimes against property ( 5 ). More studies with populations from diverse cultural contexts are needed to gain a better understanding of the subject.…”

Cross-walking personality disorder types to ICD-11 trait domains: An overview of current findings

“…There are currently eight psychometrically sound approaches to the measurement of ICD-11 trait domains, which include the empirically based algorithm for the Personality Inventory for DSM-5 (PI-D) ( 13 , 14 ), the Personality Inventory for ICD-11 (PiCD) ( 15 ), the Five-Factor inventory for ICD-11 (FFiCD) ( 16 ), The Personality Inventory for DSM-5 and ICD-11 Brief Form-Plus-Modified (PID5BF + M) ( 17 , 18 ), the Informant Personality inventory for ICD-11 (IPiC) ( 19 , 20 ), the Personality Assessment Questionnaire for ICD-11 personality traits (PAQ-11) ( 21 ), Clark et al’s scales for ICD-11 Five Personality Disorder Trait Domains ( 22 ), and the Integrative Dimensional Personality Inventory-11 (IDPI-11) ( 23 ). Five of these measures (i.e., PID-5 algorithm, PiCD, FFiCD, PID5BF + M, and PAQ-11) are being employed in the studies reviewed in the present article.…”
