Background The screening instrument for borderline personality disorder (SI-Bord) consists of a 5-item self-reported questionnaire on the key features of BPD from the DSM-5 using a 5-point Likert scale. This study investigated its validity and reliability in screening for BPD in university students. Methods A cross-sectional study was conducted on a sample of university students in Thailand between November and December 2019. An online assessment gathered demographic data and results from the SI-Bord, the Perceived Stress Scale-10 (PSS-10) and the Patient Health Questionnaire-9 (PHQ-9). Participants whose SI-Bord scores were ≥ 1 were randomly selected to be interviewed and assessed for a BPD diagnosis by four psychiatrists using the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II) as a reference point. An intraclass correlation coefficient (ICC) of 0.925 (95% CI, 0.805–0.979) ensured inter-rater reliability between the four psychiatrists. The diagnost...

INTRODUCTION The clinical heterogeneity and elevated comorbidity of Borderline Personality Disorder (BPD) have suggested the possible existence of several factors or subtypes of this construct. Studies published to date mainly show that this diagnosis could be represented either as a 1-dimensional model or 3-factor model. However, most of the studies have analyzed the factorial structure of the BPD DSM-IV criteria only using semi-structured interviews. This study has aimed to analyze the factorial structure of BPD DSM-IV criteria used in the self-report PDQ-4+. METHOD A total of 159 psychiatric outpatients with suspicion of BPD diagnosis were evaluated. Confirmatory Factor Analyses (CFA) was performed for BPD criteria in PDQ-4+ and two previously defined structures were examined and compared: a 1-dimensional model and a 3-factor model. RESULTS Both models showed good fit indexes. However, the results of the CFA showed better goodness of fit indexes (χ(2)/gl; CFI; RMSEA; TLI; AIC and...

The diagnostic criteria for Borderline Personality Disorder (BPD) are heterogeneous, and include an admixture of personality traits, behaviours, and symptoms. The BPD DSM factor structure has been extensively studied, even though results are not consistent. In this study we performed a confirmatory factor analysis (CFA) to compare the five-factor model reported by Oldham, a three-factor model, and a unidimensional model of BPD diagnosis criteria. This study validates the findings of previous studies by performing a CFA with the DSM-IV BPD criteria and information derived from the DIB-R. A sample of 338 patients referred to our outpatient BPD program participated in the study. Results of the CFA support both the hypothesized unidimensional and the three-factor models, whereas the five-factor model was not confirmed. However, the three-factor model fits better than the unidimensional model. Thus, although the DSM-IV BPD criteria conceptualize BPD as a unidimensional structure, our results give support to the idea that the three-factor model could offer a better approach to further improve the current treatment of BPD, as well as lead to a better understanding of its ethiopathogenesis and comorbidity analysis.

and women. [1] BPD usually emerges during adolescence and is related with severe morbidity. [2] The prevalence of BPD in men is 5.6%. [3] Individuals with BPD seem to have higher than expected rates of affective and impulsive disorders, [4] substance-related disorders and antisocial characteristics, [5] some types of Axis II disorders, [6,7] and impulse-spectrum disorders. [8] Approximately 10%-26% of people with BPD have a history of suicide attempt. [9,10] They have a history of conflicts in Background: Screening for personality disorders through reliable instruments is of high importance for clinical and preventive purposes. Examining the psychometric properties of measures in societies with diverse cultures can improve their external validity. This research is specifically aimed to studying psychometric properties of the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) in a sample of Iranian men serving military service. Materials and Methods: The Persian version of the MSI-BPD was prepared through forwarding translation, reconciliation, and back-translation. A sample of 254 soldiers was selected through the convenience sampling method in Tehran and completed a set of questionnaires, including the MSI-BPD, The Deliberate Self-harm Inventory (DSHI), Borderline Personality Scale (STB), Cognitive Flexibility Inventory (CFI), and Self-Compassion Scale (SCS) Short-Form. The construct validity of the MSI-BPD was assessed using confirmatory factor analysis and divergent and convergent validity. Internal Consistency and test-retest reliability (2 weeks'interval) were used to evaluate the reliability. Data analysis was conducted using LISREL (version 8.8) and SSPS (version 22) software. Results: MSI-BPD and its subscales were found to be valid and reliable measures, with good internal consistency and good test-retest reliability among soldiers. In terms of convergent validity, MSI-BPD and subscales showed a significant positive correlation with self-report measures of DSHI and STB. MSI-BPD and subscales showed negative correlation with SCS Short-Form and CFI, thus demonstrated a good divergent validity. The results of this study also provide support for both one-factor and two-factor models of the MSI-BPD. Conclusion: The MSI-BPD showed good validity and reliability, making it a useful measure to Screening borderline personality disorder in the Iranian population. Screening offers a means of identifying persons for more detailed evaluation for early intervention and for research. The MSI-BPD is an efficient instrument suitable for screening purposes among soldiers.
Exploring the clinical validity of borderline personality disorder components
Comprehensive Psychiatry, 2013
Borderline personality disorder (BPD) is recognized as a complex syndrome, resulting in a heterogeneous diagnostic category. Besides the characteristics of the disorder itself, comorbid disorders play an important role in this complexity. The aim of the study is to analyze the clinical validity of 3 components for BPD Diagnostic and Statistical Manual of Mental Disorders criteria-called affective dysregulation, behavioral dysregulation, and disturbed relatedness-investigating differences in patterns of comorbidity. For this purpose, 365 patients with suspected BPD were included in the study. To test our hypothesis, patients were classified into 5 clusters using a K-cluster analysis to study the clinical validity of the 3 components based on the 3-factor model of BPD. Differences in comorbidity, previous suicide attempts, and self-harm behaviors among the defined clusters were analyzed. Between-cluster differences were observed for Axis I and Axis II disorders as well as in the frequency of suicide attempts and in self-harm behaviors. The study of BPD based on the 3 components seems to be more useful than the study of BPD as a unitary construct to help further our understanding of this complex disorder. In the present study, the 3 BPD components have allowed us to analyze the complex comorbidity of BPD patients. This solution could be considered an interesting way to clarify BPD etiology, diagnosis, and treatment efficacy.

Interview methods are widely regarded as the standard for the diagnosis of borderline personality disorder (BPD), whereas self-report methods are considered a time-efficient alternative. However, the relative validity of these methods has not been sufficiently tested. The current study used data from the Collaborative Longitudinal Personality disorder Study to compare diagnostic base rates and the relative validity of interview and self-report methods for assessing functional outcome in BPD. Although self-report yielded higher base rates of criteria endorsement, results did not support the common assumption that diagnostic interviews are more valid than self-reports, but instead indicated the combined use of these methods optimally identifies BPD criteria.
A further validation of the Minnesota Borderline Personality Disorder Scale
Personality Disorders: Theory, Research, and Treatment, 2014
Previous research indicates that borderline personality disorder (BPD) is well conceptualized as a dimensional construct that can be represented using normal personality traits. A previous study successfully developed and validated a BPD measure embedded within a normal trait measure, the Minnesota Borderline Personality Disorder Scale (MBPD). The current study performed a further validation of the MBPD by examining its convergent validity, external correlates, and heritability in a sample of 429 female twins. The MBPD correlated strongly with the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II) screener for BPD and moderately with external correlates. Moreover, the MBPD and SCID-II screener exhibited very similar patterns of external correlations. Additionally, results indicated that the genetic and environmental influences on MBPD overlap with the genetic and environmental influences on the SCID-II screener, which suggests that these scales are measuring the same construct. These data provide further evidence for the construct validity of the MBPD.

The present study sought to assess the performance of the Borderline Features (BOR) Scale of the adolescent version of the Personality Assessment Inventory (Morey, 2007b) in 2 high-risk samples: inpatient and justice-involved adolescents. This study is the first to evaluate the BOR scale in high-risk adolescent samples, outside the initial standardization studies. Across both samples (N Clinical ϭ 327, N Forensic ϭ 151), results indicated good internal consistency. Confirmatory factor analysis indicated poor fit of the 4-factor structure proposed by the measure's authors. Convergent validity and receiveroperating characteristics analyses, conducted in the clinical sample, indicated that the adolescent version of the Personality Assessment Inventory BOR scale had good diagnostic accuracy for predicting a borderline personality disorder diagnosis (via structured interview). Findings suggest that the BOR scale has adequate internal consistency, convergent validity, and clinical utility, although areas for future measure evaluation (including factor structure) remain. Still, the BOR scale may partially address the current hesitation to assess borderline personality disorder features in high-risk youth because it is embedded within a broadband psychopathology measure. Public Significance Statement Borderline personality disorder (BPD) is an impairing psychological disorder that commonly begins to emerge during adolescence, but the assessment of BPD in adolescents is uncommon and psychometric data are limited. The current study reported on the psychometric properties of the adolescent version of the Personality Assessment Inventory for assessing BPD among 2 high-risk groups: inpatient and justice-involved adolescents.
