The elephant in the room: Is betrayal trauma associated with borderline personality disorder?

Borderline personality disorder (BPD) has been found to be closely linked to childhood trauma, particularly betrayal trauma. In our study, we aimed to investigate the association between betrayal trauma and anxiety among young adults. We assessed a total of 305 young adults using a Google form utilizing three assessment tools: the 10-item McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), the 12-item Brief Betrayal Trauma Survey (BBTS), and the 7-item Generalized Anxiety Disorder (GAD-7) to evaluate borderline personality traits, betrayal trauma experiences, and anxiety level. Our findings revealed that 22% [95% confidence interval (CI) 17.7 to 26.9] of the participants screened positive for BPD on MSI-BPD assessment; self-reported anxiety as reported by GAD-7 was observed in 27.9% (95% CI 23.1 to 33.2), while 82% (95% CI 77.3 to 85.9) reported experiencing betrayal trauma. A significantly higher proportion of individuals with BPD (97%) reported experiencing betrayal trauma compared to those without the disorder. High betrayal trauma [odds ratio (OR) 8.14, 95% CI 3.06 to 21.67] and medium betrayal trauma (OR 7.06, 95% CI 2.64 to 18.92) were significantly associated with the diagnosis of BPD. The associations held true across genders, although they were stronger in females. Our study highlights the strong relationship between betrayal trauma and BPD, with significant implications for the development of anxiety in young adults. These findings underscore the importance of recognizing and addressing childhood trauma, particularly betrayal trauma, in individuals at risk for BPD.

Exploring the impact of childhood maltreatment and BPD on impulsivity in crimes of passion.

Crimes of passion, characterized as unpremeditated impulsive aggression, have garnered increasing attention in recent years. Impulsivity, a major factor in crimes of passion, is also a common feature of various health conditions, including Borderline Personality Disorder (BPD). Childhood maltreatment is considered a significant precursor to BPD and is closely related to impulsivity. Although prior research has affirmed the relationship between impulsivity, childhood maltreatment, BPD, and criminal behavior, few studies have examined these variables' interconnections within the context of crimes of passion. This study seeks to explore the relationship between childhood maltreatment, BPD, and impulsivity in crimes of passion, assessing the former's impact on the latter. Our research examined 133 crimes of passion offenders and 149 other offenders from the Shenzhen male prison in China. All 282 participants completed The Abbreviated Version of The Barratt Impulsiveness Scale (ABIS), The UPPS Impulsivity Scale (Urgency, Premeditation, Perseverance, Sensation Seeking), The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), and The Childhood Trauma Questionnaire (CTQ). Our findings indicated that (1) crimes of passion offenders scored significantly higher in emotional neglect, physical neglect, and overall childhood maltreatment than did other offenders, and childhood maltreatment scores were notably higher in the high BPD trait group. (2) Crimes of passion offenders demonstrated significantly elevated impulsivity in attention and nonplanning scales compared to other offenders. Impulsivity scores across all scales were also significantly higher in the high BPD trait group. (3) Emotional neglect was found to significantly influence the urgency scale in crimes of passion offenders. An interaction effect was noted between physical abuse and high BPD traits, leading to increased impulsivity in crimes of passion offenders. This study underscores the predictive roles of childhood maltreatment and BPD in determining impulsivity within the context of crimes of passion.

Psychopathology and Theory of Mind in patients with personality disorders

ObjectivePeople with mental disorders frequently suffer from deficits in the ability to infer other’s mental states (Theory of Mind; ToM). Individuals with borderline personality disorder (BPD) show ToM deficits characterized by exceeding ToM (over-attributions of mental states). The present study analyzed associations between ToM, BPD severity, and depression severity in patients with BPD and other personality disorders.MethodWe analyzed ToM abilities in 128 patients with BPD and 82 patients with ‘mixed and other personality disorders’ (MOPD). MOPD are diagnosed if symptoms of multiple personality disorders are present without any set of symptoms being dominant enough to allow a specific diagnosis. We used the movies for the assessment of social cognition (MASC) to measure ToM abilities, the Patient Health Questionnaire (PHQ-9) to assess severity of depression and the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) to assess the severity of BPD symptoms.ResultsBoth symptoms of BPD and depression were associated with exceeding ToM in separate regressions. Using a stepwise regression, only the association of depression severity with exceeding ToM was reliable. Patients with BPD and MOPD did not differ in exceeding ToM. Age was most reliably associated with ToM.ConclusionThe results imply that exceeding ToM is associated with general psychopathology instead of BPD-symptoms in specific. Patients with MOPD show deficits similar to BPD patients.

Investigating gender-based differential item functioning on the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD): An item response theory analysis.

The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) is a popular screening tool for identifying people who may have borderline personality disorder (BPD). However, because women are more frequently diagnosed with the disorder than men, it is possible that the MSI-BPD differs in its ability to identify BPD as a function of gender identity. Using item response theory (IRT), we sought to determine if components of the MSI-BPD would demonstrate differential item functioning (DIF), such that one gender identity would be more likely to endorse certain items. Twenty-two thousand thirty-five college undergraduates (14,305 women) aged 18-55 years (M = 18.77, SD = 1.75) were assessed using the MSI-BPD as part of a subject pool screening between 2008 and 2019. The MSI-BPD contains 10 items that are measured dichotomously, and the authors recommend a cut-off of 7 of 10 items endorsed to maximize sensitivity and specificity to BPD. Results suggested that a two-parameter model was the best fit to the data and that unidimensionality and local independence assumptions were met. The following items demonstrated DIF: self-harm/suicidality, affective lability, abandonment, impulsivity, and anger. At equal levels of the latent construct of BPD, women were more likely to endorse self-harm/suicidality, affective lability, and abandonment. Women were more likely to endorse impulsivity at higher levels of BPD, and men were more likely to endorse anger at lower levels of BPD. Ultimately, the effect sizes of these differences were small, however, and likely do not impact the individual's overall outcome on the measure.

Development and Preliminary Evaluation of a Rapid Screening Tool for Detecting Borderline Personality Disorder in People Aged over 60 Years

ABSTRACT Objectives Screening and diagnostic instruments for Borderline Personality Disorder (BPD) are not validated in people aged over 60. We report a pilot study examining the sensitivity and specificity of a de-novo screening instrument in older adults. Methods The BPD-OA screening tool incorporates DSM 5 and literature describing the expression of BPD in older adults. This study was conducted using a case control design. The Diagnostic Interview for Borderlines–Revised (DIB-R) and the McLean Screening Instrument for BPD (MSI-BPD) were used as comparators. Comprehensive assessment by psychiatric teams determined participants to be (i) BPD-positive (n = 22) or (ii) BPD-negative (gender matched; n = 21). Results The BPD-OA was the most sensitive instrument for discriminating older adult BPD from non-BPD participants (sensitivity = 0.82). No significant relationship was found between the BPD-OA score and age in BPD-diagnosed participants (r = −0.181, n = 21, p = .432). Participant age explained 3.2% of the variance in BPD-OA scores. Of the 21 BPD-negative participants, eight false positives experienced prominent mood disorders (specificity = 0.62). Conclusions The BPD-OA screening tool is clearly superior to instruments validated for use in younger people. Further refinement and evaluation will enhance its sensitivity and specificity. Clinical Implications Detection of BPD in older adult care settings will improve outcomes for patients, families, and staff through better understanding and appropriate management and treatment strategies.

Disease Burden Of Co-Occurring Borderline Personality Disorder In Patients With Bipolar Disorder

IntroductionIn recent years, advances in the areas of both bipolar disorder (BD) and borderline personality disorder (BPD) have generated considerable interest in the relationship between these two conditions, since that they are commonly comorbid.ObjectivesWe aimed to investigate the impact of BPD on course of illness in patients with BP.MethodsWe conducted a cross-sectional, descriptive and analytical study among 30 psychiatric outpatients diagnosed with BD in the Psychiatry « B » department, Hedi Chaker Hospital (Sfax, Tunisia). The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) was used to screen for BPD. Clinical outcomes (hospital stays, comorbidities, suicidality…) were compared between BD- patients with or without BPD comorbidity.Results The mean age was 41.63 years, with a sex ratio of ½. Among the patients, 2/3 were diagnosed with BD-I, while 1/3 presented a BD-II. Physical comorbidities, comorbid anxious and eating disorders were noted respectively in 36.7%; 16.7% and 43.3% of patients. Suicidal attempts were reported in 46.7% of cases. According to MSI-BPD, a comorbid BPD was noted in 30% of our sample. Patients with BD-II were significantly more likely to present BDP traits (50%) than those with BD-I (20%) (p<0.001). Patients with BPD were significantly more likely to attempt suicide (p=0.033), and to present physical comorbidities (p<0.001) and comorbid eating disorders (p<0.001).ConclusionsOur study showed that BPD darkens the prognosis of BD, because of worse outcomes related to suicide, physical and psychiatric comorbidities. Thus, its co-occurrence complicates the management of BD.DisclosureNo significant relationships.

The Duration in Treatment With Electroconvulsive Therapy Among Patients Screening Positive or Negative for Borderline Personality Disorder Traits: A Retrospective Cohort Study.

While emerging evidence suggests that electroconvulsive therapy (ECT) is an effective treatment for depressive symptoms in patients with co-occurring borderline personality disorder (BPD) traits, it is unclear whether the presence of BPD traits modulates the tolerability of ECT. This study estimates the association between BPD traits and retention in acute course ECT treatment. This study used a retrospective cohort of patients receiving ECT between 2015 and 2020 and who were assessed using the McLean Screening Instrument for BPD, the Quick Inventory of Depressive Symptomatology Self-Report 16-item scale, and the Montreal Cognitive Assessment before initiating treatment. One thousand five hundred eight patients received ECT during the study period, of whom 277 (18.4%) screened positive for BPD traits. Borderline personality disorder traits were associated with a higher odds of remaining in ECT for at least 10 treatments (adjusted odds ratio, 1.502; 95% confidence interval, 1.11-2.02; P = 0.007). Among individual symptom domains, only endorsing chronically feeling empty was associated with duration in ECT treatment. Among patients receiving ECT, screening positive for BPD traits was associated with a higher odds of receiving at least 10 ECT treatments. These results support the overall tolerability of ECT in patients with BPD traits.

Brazilian adaptation of the McLean Screening Instrument for Borderline Personality Disorder.

Borderline personality disorder (BPD) is a serious and extremely prevalent mental disorder. Early diagnosis is vital for treatment. However, there are no specific screening instruments validated for Brazilian Portuguese. This study aimed to adapt the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) to the Brazilian context. The MSI-BPD is a self-report instrument based on the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), that enables fast and reliable assessment of BPD, with measures of sensitivity (SN) and specificity (SP) similar to the diagnostic interview for the DSM-5 (Structured Clinical Interview for DSM-V Axis II Disorders [SCID-II]), taken as the gold standard. Two independent translations, a synthesis version, back-translation, and analysis by experts were employed to create the final version of the instrument in Brazilian Portuguese. The translated instrument was administered to 1,702 adults aged 18-59 years to verify evidence of validity relating to content, internal structure, relationship with other variables, and reliability. The exploratory and confirmatory factor analyses show that the one-factor structure is adequate. The scale showed satisfactory internal consistency (Kuder-Richardson coefficient [KR-20] of Cronbach's alpha = 0.691) and good test-retest reliability (intraclass correlation coefficient [ICC] = 0.802). Logistic regression analysis using the Personality Inventory for the DSM-5-Brief Form (PID-5-BF) (DSM-5) as reference established an ideal cut-off point of eight symptoms, with adequate SN (0.79) and SP (0.75), similar to the original instrument. The area under the curve (AUC) was 0.830 (95% confidence interval: 0.802-0.858), with a positive predictive value of 89.2%. The Brazilian version of the MSI-BPD has adequate psychometric properties for use as a BPD screening tool by clinicians.

Validity and reliability: The psychometric properties of the Persian version of Short Form of the Impulsiveness Questionnaire UPPS-P in Iran

BACKGROUND:Impulsiveness is a multidimensional and multifaceted construct that plays an important role in understanding various psychopathology and problematic behavior. It is necessary to study the psychometric properties of instruments in the new culture before its scientific application, and it also contributes to external validity. The current study was conducted to determine the psychometric properties of the Persian version of Short Form of the Impulsiveness Questionnaire UPPS-P (SUPPS-P) in a sample of male soldiers serving in the military service.MATERIALS AND METHODS:The present research design is cross-sectional in 2019–2020. The Iranian version of the SUPPS-P was prepared across forwarding translation, reconciliation, and back-translation. The research sample included 254 soldiers who were selected via convenience sampling method and completed a set of scales, including the SUPPS-P scales, short-form self-compassion scale, McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), Cognitive Flexibility Inventory (CFI), Perth Alexithymia Questionnaire (PAQ), and the Deliberate Self-harm Inventory (DSHI). The construct validity of SUPPS-P scale was measured using confirmatory factor analysis and convergent and divergent validity. For reliability, Cronbach's alpha and test–retest reliability (with 2 weeks interval) were used. Data were analyzed using LISREL software (version 8.8) and SPSS version 22.RESULTS:The results showed that the SUPPS-P scale is a reliable and valid scale with acceptable internal consistency and acceptable test–retest reliability among soldiers. In terms of convergent validity, SUPPS-P showed a significant positive correlation with measures of MSI-BPD, PERS, and DSHI. SUPPS-P showed a negative correlation with self-compassion and cognitive flexibility, thus demonstrated a good divergent validity. The results of this study also provide support for the five-factor model of the SUPPS-P scale.CONCLUSION:The SUPPS-P instrument showed acceptable validity and reliability and could be useful in assessing impulsivity in Iranian society. The SUPPS-P scale shows notable promise as a measure for use in impulsivity research and clinical settings.

Chronic feelings of emptiness in a large undergraduate sample: Starting to fill the void.

Chronic emptiness in borderline personality disorder (BPD) has received little empirical attention. We sought to examine basic properties of a single chronic emptiness item, including prevalence, reliability, validity, the relation of the emptiness item to other BPD criteria, and measures of personality. Undergraduates enrolled in psychology courses over 12 years' time completed the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) (N = 22,217). Subsets of participants completed the International Personality Disorder Examination-Screening Questionnaire (IPDE-SQ) (N = 2732), The Revised NEO Personality Inventory (Anxiety, Angry Hostility, Depression, Positive Emotions [reversed], and Impulsivity facets) (N = 10,506), and the Depression Anxiety Stress Scales (DASS) (N = 1110) as validity indicators; 10.0% of respondents endorsed emptiness. Reliability indices suggested moderate levels of reliability between two emptiness items (r(2730) = 0.61, p < 0.001). Among BPD criteria, emptiness and identity disturbance correlated most strongly (r(22,215) = 0.81, p < 0.001). MSI emptiness was more correlated with depression on the NEO (r(10,504) = 0.43, p < 0.001) and DASS (r(1108) = 0.51, p < 0.001) than other facets of negative affect. Emptiness was more correlated with greater borderline pathology than any other MSI-BPD item (Sample 1, rtet = 0.87; Sample 2, rtet = 0.86). This criterion warrants further study and attention, especially related to assessment of BPD.

Validity and Reliability of the Urdu Version of the McLean Screening Instrument for Borderline Personality Disorder.

Introduction: Although the translation and the validation of the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) are performed in various languages and samples, no study has established the validity and reliability of the Urdu version of MSI-BPD in individuals with cardiac problems.Materials and Methods: The Urdu version of the MSI-BPD was prepared through the standard back-translation method. The translation and adaption were completed in four steps: forward translation, adaption and translation, back translation and committee approach, and cross-language validation. The sample, selected through the purposive sampling method, comprised of 150 adults with cardiac problems (men = 75 and women = 75), with an age range of 23–78 years (M = 55, SD = 10.6). The Cronbach alpha reliability and factorial validity of the MSI-BPD were assessed through confirmatory factor analysis (CFA) and Pearson correlation analyses. Internal consistency and test–retest reliability (at 2 weeks' interval) were used to evaluate the reliability. Statistical analyses were performed, using SPSS (version 22) and Structural Equation Modeling (SEM) software.Results: Preliminary analysis revealed that the overall instrument had good internal consistency (Urdu MSI-BPD α = 0.79; English MSI-BPD α = 0.77) as well as test–retest correlation coefficients for 15 days (r = 0.94).Conclusions: Findings suggested that the MSI-BPD, with important limitations, can be used as an effective preliminary screening tool to measure BPD in Urdu-speaking adults with cardiac problems. Further validations should be conducted to make the translated version of the MSI-BPD an appropriate tool to screen BPD in hospitals and mental health care settings.

Childhood abuse and borderline personality disorder features in Chinese undergraduates: the role of self-esteem and resilience

BackgroundAlthough childhood abuse is considered to be related to borderline personality disorder (BPD), few studies have elaborated on the mediating role of self-esteem and resilience in it. Thus, the present study aimed to explore the potential mediating role of resilience and self-esteem between childhood abuse and BPD.MethodsThis cross-sectional study was conducted with 4034 college students in Anhui Province, China. Participants were asked to complete Chinese versions of the following instruments: Childhood Trauma Questionnaire–Short Form (CTQ-SF), Mclean Screening Instrument for Borderline Personality Disorder (MSI-BPD), Connor-Davidson Resilience Scale (CD-RISC), and Rosenberg Self-Esteem Scale (RSES). Structural equation modeling (SEM) was used to test the mediation effects.ResultsResilience and self-esteem were found to be mediators of all three types of childhood abuse (emotional abuse, physical abuse and sexual abuse) when the types were examined separately; however, when all three types of childhood abuse were entered into the model simultaneously, neither the indirect effects nor direct effects of physical abuse or sexual abuse were found to be significant, only the association between emotional abuse and BPD features was partially mediated by resilience and self-esteem.ConclusionsSelf-esteem and resilience mediate the links between childhood abuse and BPD features, and emotional abuse is uniquely associated with BPD features.

Borderline personality traits do not influence response to TMS

Comorbid personality disorders are common in patients with major depressive disorder (MDD). Individuals with comorbid borderline personality disorder (BPD) may be less responsive to electroconvulsive therapy (ECT), but it remains unclear whether BPD affects responsiveness to transcranial magnetic stimulation (TMS). We sought to investigate the association between BPD and response to TMS. We conducted a retrospective analysis of individuals receiving TMS (n=356) at McLean Hospital. We also included individuals receiving ECT (n=1434) as a control. All individuals completed the McLean Screening Instrument for BPD (MSI-BPD) at baseline. Response to treatment was measured by the Quick Inventory of Depression Symptomatology Self-Report (QIDS-SR). We performed general linear models (GLMs) to assess the effect of BPD on treatment response to TMS and ECT. At baseline, the ECT group had a higher average QIDS-SR score (21.4 vs. 20.3, p<0.05). For both treatment groups, the number of treatments had a significant effect on depression severity. For the TMS group, there was no significant Group x Time interaction on QIDS-SR score (p=0.18). However, for individuals receiving ECT, there was a significant Group x Time interaction on QIDS-SR score (p=0.02), suggesting that BPD significantly impaired response. These results suggest that borderline personality traits did not affect treatment response to TMS for MDD. BPD traits modestly predicted response to ECT, which is consistent with the literature. These results require replication in a clinical trial.

Exploring the links among borderline personality disorder symptoms, trauma, and pain in patients with chronic pain disorders

ObjectiveChronic pain and borderline personality disorder (BPD) are commonly comorbid and jointly associated with increased symptoms of both disorders and clinical and functional impairment. Little is known, however, about specific links between these disorders. In a cross-sectional study of patients with chronic pain, we compared participants high or low on BPD symptoms on patterns of pain experience and types of child and adult traumas. MethodsAdults (N = 181) with chronic pain completed self-reports of pain severity, dimensions of pain experiencing, body coverage of pain, and clinical indicators of central sensitization (i.e., chronic hypersensitivity of the central nervous system), as well as measures of child and adult physical abuse, sexual abuse, trauma, and neglect. Participants also completed the McLean Screening Instrument for BPD. ResultsParticipants with clinically significant BPD symptoms (n = 32) reported more childhood sexual trauma, punishment, and neglect, as well as adult physical/sexual trauma, than those without elevated BPD symptoms. Among participants with clinically significant BPD symptoms, affective pain and central sensitization were elevated, potentially explained by heightened negative affect in BPD. ConclusionBPD symptoms are associated with increased clinical severity among patients with chronic pain as well as a unique manifestation of pain experiencing (i.e., increased affective pain and central sensitization in particular). Childhood trauma of all types is associated with chronic pain and BPD co-occurrence. Researchers and clinicians should assess for BPD in people with chronic pain to enhance conceptual models of the transaction between these disorders and to improve clinical care.

Validation of the French version of the McLean screening instrument for borderline personality disorder (MSI-BPD) in an adolescent sample

BackgroundThe study examines the psychometric properties of the French version of the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) created by M. Zanarini to screen borderline personality disorder in clinical and non-clinical populations.MethodIn this multicentric longitudinal study from the European Network on Borderline Personality Disorder, a sample of 84 adolescent patients from five psychiatric centres and 85 matched controls without psychiatric comorbidity completed the MSI-BPD, French version, and were interviewed with the Structured Interview for DSM-IV Personality (SIDP-IV), in order to assess the presence or absence of borderline personality disorder.ResultsThe MSI-BPD showed excellent internal consistency (α = 0.87 [0.84;0.90]). Compared to the semi-structured reference interview (SIDP-IV), the MSI-BPD showed substantial congruent validity (AUC = 0.93, CI 95%: 0.90–0.97). The optimal cut-off point in the present study was 5 or more, as it had relatively high sensitivity (0.87) and specificity (0.85). In our sample, the cut-off point (7 or more) proposed by the original developers of the MSI-BPD showed high specificity (0.95) but low sensitivity (0.63).ConclusionsThe French version of the MSI-BPD is now available, and its psychometric properties are satisfactory. The French version of the MSI-PBD can be used as a screening tool for borderline personality disorder, for clinical purposes or in research studies.

Identifying unstable and empty phenotypes of borderline personality through factor mixture modeling in a large nonclinical sample.

Borderline personality disorder (BPD) is serious, prevalent, and symptomatically heterogeneous. Identifying distinct phenotypes of BPD features promises useful diagnostic and treatment implications. Although a series of subtyping studies exist, only two have examined BPD symptom configurations while taking into account BPD severity. We used factor mixture modeling to identify discrete subtypes of BPD features, simultaneously considering symptom severity, in the largest nonclinical young adult sample to date. Undergraduates (N = 20,010; 63.86% women; Mage = 18.75, SD = 1.73) completed the McLean Screening Instrument for BPD, which was condensed to measure the 9 Diagnostic and Statistical Manual of Mental Disorders BPD criteria dichotomously. We used a model comparison approach to determine the optimal latent factor and class structure of BPD symptoms and validated classes via BPD-relevant constructs. The sample consisted of three subtypes: Asymptomatic (70%), Unstable (19%), and Empty (11%). The Unstable and Empty classes displayed elevated BPD symptomatology along a single continuum of BPD severity. Individuals in the Empty class displayed the highest levels of emptiness and dissociation, emotional distress, and attachment avoidance, whereas individuals in the Unstable class displayed a high frequency of reckless and self-damaging behaviors. Our results suggest the importance of a hybrid dimensional/categorical conceptualization of BPD as displayed in a nonclinical sample. Unstable and Empty classes may be associated with different treatment targets for subthreshold BPD presentations. The findings are discussed in terms of their clinical implications regarding diagnosis, treatment, and theoretical conceptualization of BPD.

Screening borderline personality disorder: The psychometric properties of the Persian version of the McLean screening instrument for borderline personality disorder

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.

Screening for Borderline Personality Disorder With the McLean Screening Instrument: A Review and Critique of the Literature.

Borderline personality disorder (BPD) is underdiagnosed in clinical practice. One approach towards improving diagnostic detection is the use of screening questionnaires. It is important for a screening test to have high sensitivity because the more time-intensive/expensive follow-up diagnostic inquiry will presumably only occur in patients who are positive on the initial screen. The most commonly studied self-report scale specific for BPD is the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD). We summarize the performance of the scale across studies, examine the performance of the scale using different cutoff scores, and highlight the approach used by investigators in recommending a cutoff score. Most studies of the scale have taken a case-finding approach in deriving the cutoff score on the scale instead of a screening approach. For the purposes of screening, it may be more appropriate for the cutoff score on the MSI-BPD to be less than the currently recommended cutoff of 7.

From categorical diagnosis to dimensional assessment of borderline personality

Recent research suggested that personality disorders could be diagnosed as a continuous phenomenon. Therefore, in our study we examined whether the dimensional model of pathological personality traits could be applied to the assessment of borderline personality1. For this purpose, we modified an existing measure of borderline personality, the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), and scrutinized its psychometric properties (i.e., reliability, factorial structure, criterion validity). To assess criterion validity we calculated correlations with pathological personality traits. Our sample comprised 354 participants (67.8% women). Confirmatory factor analysis revealed that the modified MSI-BPD measures borderline per-sonality as a global construct, giving one-factor structure. The reliability of the measurement was excellent (α = .90). Moreover, we found positive associations between borderline personality and all five pathological person-ality traits, which supports the validity of the continuous assessment of borderline personality. Our findings sug-gest that the DSM-5 dimensional model may be applied in the assessment of borderline personality.
