Correction to: A Psychometric Review of the Personality Inventory for DSM-5 (PID-5): Current Status and Future Directions

Validation of the Personality Inventory for DSM-5–Brief Form (PID-5-BF) with Iranian University Students and Clinical Samples: Factor Structure, Measurement Invariance, and Convergent, Discriminant, and Known-Groups Validity

The Personality Inventory for DSM-5, Brief Form (PID-5-BF) was developed to assess DSM-5's Alternative Trait Model for Diagnosing Personality Disorders (AMPD). This study aimed to examine the factor structure, internal consistency, measurement invariance, and convergent, discriminant, and known-group validity of the Persian PID-5-BF with 941 university students (aged 18-67, M age= 28.36, SD = 9.09, 39.1% males) and 178 male from a clinical (aged 18-60, M age= 33.77, SD = 10.60) sample in Iran. Confirmatory factor analyses supported the five-factor model in both groups, being fully and partially invariant across gender and study groups, respectively. PID-5-BF subscales were internally consistent, yielded expected associations with other personality variables, and differentiated the student sample from the clinical group, supporting the measure's convergent, discriminant, and known-group validity. Our results indicated that the PID-5-BF holds promise as a screening measure of dimensional maladaptive personality traits in Iranian students and clinical samples.

Personality inventory for DSM-5 brief form(PID-5-BF) in Chinese students and patients: evaluating the five-factor model and a culturally informed six-factor model

BACKGROUND

The Personality Inventory for DSM-5 Brief Form (PID-5-BF) is a 25-item measuring tool evaluating maladaptive personality traits for the diagnosis of personality disorders(PDs). As a promising scale, its impressive psychometric properties have been verified in some countries, however, there have been no studies about the utility of the PID-5-BF in Chinese settings. The current study aimed to explore the maladaptive personality factor model which was culturally adapted to China and to examine psychometric properties of the PID-5-BF among Chinese undergraduate students and clinical patients.

METHODS

Seven thousand one hundred fifty-five undergraduate students and 451 clinical patients completed the Chinese version of the PID-5-BF. Two hundered twenty-eight students were chosen randomly for test-retest reliability at a 4-week interval. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to discover the most suitable factor structure in China, measurement invariance(MI), internal consistency, and external validity were also calculated.

RESULTS

The theoretical five-factor model was acceptable, but the exploratory six-factor model was more applicable in both samples (Undergraduate sample: CFI = 0.905, TLI = 0.888, RMSEA = 0.044, SRMR = 0.039; Clinical sample: CFI = 0.904, TLI = 0.886, RMSEA = 0.047, SRMR = 0.060). In the Chinese six-factor model, the Negative Affect domain was divided into two factors and the new factor was named "Interpersonal Relationships", which was in line with the Big-Six Personality model in Chinese. Measurement invariance across non-clinical and clinical sample was established (configural, weak, strong MI, and partial strict MI). Aside from acceptable internal consistency (Undergraduate sample: alpha = 0.84, MIC = 0.21; Clinical sample: alpha = 0.86, MIC = 0.19) and test-retest reliability(0.73), the correlation between the 25-item PID-5-BF and the 220-item PID-5 was significant(p < 0.01). The six PDs measured by Personality diagnostic questionnaire-4+ (PDQ-4+) were associated with and predicted by expected domains of PID-5-BF.

CONCLUSIONS

Both the theoretical five-factor model and the exploratory six-factor model of the PID-5-BF were acceptable to the Chinese population. The five-factor model could allow for comparison and integration with other work on the original theoretical model. However, the Chinese six-factor structure may be more culturally informed in East Asian settings. In sum, the PID-5-BF is a convenient and useful screening tool for personality disorders.

Psychometric Properties of the Personality Inventory for DSM-5 (PID-5) in Brazilian Samples

Abstract This study aimed to investigate the psychometric properties of the Personality Inventory for DSM-5 (PID-5) in Brazilian community and clinical samples. This research included 1,210 people, 554 of them with psychopathology indicators. The participants answered the PID-5 and the Self-Reporting Questionnaire, in addition to a sociodemographic and health data questionnaire that included the six items of the suicidality module of the Mini International Neuropsychiatric Interview. The results showed that the 25 facets of the PID-5 had adequate reliability coefficients and evidence of unidimensionality. The instrument’s five-factor structure was replicated with high levels of congruence with the representative sample from North America. PID-5 scores were statistically different between clinical and community groups and were positively correlated with measures of suicide risk and psychopathological symptoms. This study presents the psychometric properties of PID-5 and its suitability for use in the Brazilian population.
