Utility of Multiple Specifiers for Subtyping Oppositional Defiant Problems: Investigating Multiple Psychopathy Dimensions as Specifiers.

Past research has speculated that using grandiose-manipulative (GM) and daring-impulsive (DI) traits, rather than solely callous-unemotional (CU) traits, could better inform subtyping youths with behavioral problems. However, this approach remains largely untested. To further enhance our understanding of this matter, the current study utilized self-report (n = 2,381) and parent-report (n = 1,846) data to examine the utility of three psychopathic dimensions as specifiers for oppositional defiant problems (ODP). Findings showed that ODP was a significant predictor of negative outcomes, while the GM, CU, and DI traits emerged as significant predictors of theoretically and clinically relevant external variables (e.g., conduct problems and proactive aggression), independent of ODP (and age, gender, and socioeconomic status), forming the potential foundation for the development of specifiers for ODP. Furthermore, children presenting ODP alongside heightened levels of the three psychopathic traits demonstrated notably higher scores in important external variables compared to other groups, including but not confined to the subgroup of children with ODP and high CU trait levels. Findings provide preliminary support for employing GM and DI traits as specifiers for ODP. However, more comprehensive evaluations of these specifiers' utility would help inform ongoing discussions before definitively concluding they should be included in diagnostic manuals.

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.

The Persian version of the Youth Psychopathic Traits Inventory-Short Version (YPI-S): A psychometric evaluation.

Studies on the psychopathy construct are mostly limited to Western cultures, and there is a lack of research in this area in non-Western countries, specifically in Iran. The present study aimed to examine the factor structure, internal consistency, and convergent validity of the Persian version of the Youth Psychopathic Traits Inventory-Short Version (YPI-S) with a sample of 668 school-attending adolescents in Iran (46% girls; Mage = 16.35). Confirmatory factor analysis supported the proposed three-factor model. While the internal consistency of some YPI-S scores was unsatisfactory, the YPI-S scores showed the expected relations with external correlates (e.g., aggression, hyperactivity), supporting the validity of YPI-S scores. The authors' results supported the YPI-S for assessing psychopathic traits in Iranian adolescents. The modification of the YPI-S factor structure, the low factor loadings of some YPI-S items, and the inadequate internal consistency of some YPI-S dimensions indicate cultural influences on the assessment of cross-cultural traits.

Psychometric properties of the Persian version of short-form five factor borderline inventory (FFBI-SF).

BACKGROUND: The Five-Factor Borderline Inventory-Short Form (FFBI-SF) is a self-report measure developed to assess traits of Borderline Personality Disorder (BPD) from the perspective of the Five-Factor Model of general personality. This study was designed to examine the factor structure, internal consistency, and convergent/discriminant validity of the Persian FFBI-SF in a sample of Iranian university students. METHODS: A total of 641 university students (M-age = 28.04, SD = 8.21, 66.7% women) completed the online forms of the FFBI-SF, PID-5-BF, and Mini IPIP. RESULTS: Confirmatory factor analysis supported the original and modified (without item 47) twelve-factor models. Also, Cronbach's alpha (α) for the FFBI-SF scores ranged from unacceptable to excellent ranges. However, when relying on MIC values to measure internal consistency, the FFBI-SF Total and subscale scores demonstrated adequate internal consistency. Finally, the FFBI Total and subscale scores showed the expected relations with other personality measures scores (e.g., Neuroticism, Antagonism, and Conscientiousness), which supports the validity of the interpretation of the FFBI-SF scores. CONCLUSIONS: The findings indicated that FFBI-SF is a useful tool with sound psychometric properties for assessing BPD traits in Iranian students and may spark research in other Iranian settings (e.g., community and clinical samples).

Psychometric properties of the persian version of the inventory of statements about self-injury (ISAS).

BACKGROUND: Non-suicidal self-injury (NSSI) is a serious public health problem prevalent among adolescents and young adults. The present study examines the factor structure, internal consistency, and validity of the Persian version of the Inventory of Statements About Self-injury (ISAS), a self-report measure designed to comprehensively assess non-suicidal self-injury (NSSI). METHODS: A total of 655 Iranian school-attending adolescents completed study measures online, and 246 youth (37.70 %) (M age = 15.38, SD ± 0.50; 53 % female) reported a history of NSSI at least once during their lifetime. RESULTS: Confirmatory factor analysis supported the proposed two-factor model of ISAS (i.e., Interpersonal and Intrapersonal dimensions), which were internally consistent and yielded direct associations with converging correlates (e.g., depression, anxiety, irritability, and anger). CONCLUSIONS: Findings indicated that the Persian version of the ISAS has sound psychometric properties and is a valid and reliable self-report measure of NSSI.
