Clinician-rated ICD-11 trait domains and personality disorder types.

The International Classification of Diseases (11th edition; ICD-11) has adopted a classification of personality disorders (PDs) that abolishes the established International Classification of Diseases (10th edition; ICD-10) PD types in favor of global severity and stylistic trait domain specifiers. The goal of the current study was to describe the empirical relationship between traditional PD types and the ICD-11 trait domains, which is anticipated to inform and guide clinicians in this profound transition. A total of 246 patients were rated by their clinicians. The Informant-Personality Inventory for ICD-11 was used to rate ICD-11 trait domains while PD types were assigned categorically according to ICD-10. Empirical associations were investigated by means of bivariate correlation and logistic regression analyses with bootstrapping. Results overall showed expected and conceptually meaningful associations between ICD-11 trait domains and categorical ICD-10 PD types, with only a few unexpected deviations. Findings suggest that ICD-11 trait domains capture stylistic features of the established PD types in a conceptually coherent manner. These findings may facilitate continuity and guide translation between categorical PD types (i.e., ICD-10 and Diagnostic and Statistical Manual of Mental Disorders [fifth edition]) and the new ICD-11 classification in mental health care. Future research should seek to replicate these findings in various clinical settings while also integrating the essential PD severity classification.

Women in acute forensic psychiatric care: comparison of clinical, sociodemographic, and detention-related characteristics in pretrial detention, sentence execution, and court-ordered treatment

Compared to men inmates, women display decreased prevalence of severe mental disorder but increased occurrence of substance use disorders (SUD) and higher rates of previous contacts with mental health services. The group of women in detention is highly heterogeneous according to the status of incarceration (pre-trial detention (PTD), sentence execution (SE) and court ordered treatments (COT)). Studies focusing on the comparison of sociodemographic patterns, detention-related and clinical variables between these groups are still lacking. We explored these parameters in 136 women admitted for acute psychiatric care in the sole Geneva forensic unit during a nine year period (2014–2023). Sociodemographic and detention-related data included age, nationality, marital status, presence of children, education attainment, most frequently speaking language, social support, employment before conviction and type of offenses. Clinical variables included the main ICD-10 diagnosis, presence of concomitant SUD, type of personality disorders, presence of suicidal thoughts and attempts at admission, as well as number and mean duration of stays. PTD and SE women had at least 9 years of formal education in 38.9% and 30.3% of cases. Most women in PTD (77.7%), SE (56.6%) and COT (56.2%) groups were Swiss or European citizens. The level of French knowledge was excellent in most of the cases. 43.8% of COT women had at least one child and this percentage is even higher for PTD and SE cases. The employment rate before conviction was also quite high, mainly for PTD and SE (61.1% and 60.6%) and, in a lesser degree, for COT (43.8%) women. Significant social support was present in the vast majority of women without any significant group difference. The distribution of type of offenses did not differ between the three types of detention with a predominance of physical violence, and drug trafficking. The number of stays during the period of reference was significantly higher in COT compared to both SE and PTD women. History of previous inpatient care was also significantly more frequent in COT that SE and PTD women. Adjustment and affective disorders were more often found in SE and PTD cases, these diagnoses were absent in the COT group. In contrast, a main diagnosis of psychotic disorders was found in 62.5% of COT cases compared to only 21.2% in SE and 24.1% in PTD cases. The number of stays, history of inpatient care and diagnosis of psychosis were independent predictors of COT status. In conclusion, the present data reveal the good social integration and emotional support of women needing acute psychiatric care in prison independently of the type of detention. Clinically, women in PTD and SE display more often emotional distress whereas those in COT suffer from acute psychotic symptoms with previous history of psychiatric care and multiple inpatient stays.

Forensic psychiatric examination of terrorist-related criminal cases: clinical and social characteristics of the sub-experts, analysis of the expert case

In recent years, due to changes in the socio-political situation, including at the international level, the number of terrorism-related criminal cases has increased, and, therefore, the number of forensic psychiatric examinations conducted in this category of cases has risen. To date, there is a lack of any scientific studies or analytical reviews devoted to the problem of forensic examination of suspects and the accused involved in such criminal cases. The article presents the results of a review of cases of outpatient complex forensic psychological and psychiatric examinations in terrorism-related criminal cases conducted on the basis of the Department of Forensic Psychiatric Examination, Psychiatric Clinical Hospital in Moscow, from 2020 to 2023. In total, 25 cases were described and analyzed, clinical and social characteristics were studied, and an overview of expert solutions was given. An analysis of one expert case was carried out. During the examinations, 56 % of the examinees did not show symptoms of mental illness when committing the incriminated criminal act, while 36 % of the examinees in the sample were diagnosed with a mental disorder. The diagnoses included mild cognitive disorder, various types of personality disorders (emotionally unstable, schizoid, with mixed features), alcohol abuse, as well as paranoid and undifferentiated forms of schizophrenia. Based on the conducted research, it is concluded that no confessional model of religious or other consciousness in itself is a source of terrorism, including its political form. Predisposition to terrorist manifestations is a multi-level phenomenon and enters an active phase due to certain «triggers» that operate at the individual, group or mass level, which depends, among other things, on psychopathological factors.

Personality disorder type only sometimes matters: An exploration of patient's personality disorder as a source of variance in early therapeutic alliance.

The study aimed to analyse personality disorders among patients in the early phase of psychotherapy as a source of variance in the quality of the emerging alliance. The sample consisted of 131 individual psychotherapy patients with borderline (BPD), narcissistic (NPD), dependent (DPD) and obsessive-compulsive (OCPD) personality disorders and 131 psychotherapists. Different sources of alliance estimation were included. Therapeutic alliance was operationalized on several dimensions. The hypothesis was tested using an independent samples one-way analysis of variance. The study revealed a significant effect of personality disorder type on early therapeutic alliance quality. BPD patients rated their early alliance the lowest compared to NPD, DPD and OCPD patients. This trend was dominant and replicated regardless of who rated the alliance and which dimension of alliance was estimated. NPD, DPD and OCPD patients have better initial therapeutic alliances than BPD patients, and their alliances do not differ significantly. BPD patients build weaker alliances, and what poses a challenge for them is not only developing a strong and close bond but also conceptualizing goals and reaching agreement on tasks.

Cognitive–behavioural therapy as a comprehensive treatment for personality disorders

SUMMARY Personality disorders are a group of psychological disorders characterised by a developmental nature, long-lasting impairment and emotional suffering. Personality disorders have an estimated prevalence rate of approximately 8% in community settings, but in in-patient settings the rate might be as high as 76%. Cognitive–behavioural therapies (CBTs) include psychotherapies that emphasise the identification and modification of maladaptive thought patterns and behaviours that contribute to the maintenance of psychological disorders. CBTs have demonstrated their effectiveness in treating various types of personality disorder. This article focuses on the nature of personality disorders and their categorial and dimensional assessment and neurobiology. We present three influential CBT models used in personality disorders: schema therapy, cognitive interpersonal therapy and dialectical behaviour therapy. For each one, we outline the rationale, intervention strategies and therapeutic techniques, with practical examples and summary tables to illustrate their application.

Cultural Differences, Diagnosis, and the Intervention in Adolescence in Borderline Personality Disorder

The previous study showed that borderline personality disorder was strongly associated with childhood trauma and developed personality traits into adolescence that could lead to borderline personality disorder. Research also indicated a cultural difference in the psychopathology and diagnosis of borderline personality disorder in both adults and adolescents. A borderline personality disorder is a type of personality disorder that has symptoms around unstable emotions, dissociation and fear of being abandoned. Although having deviant behaviour was a significant risk factor in detecting borderline personality disorder, it could be less potent in non-western cultures like China and India. Merging cultural differences and the criteria of borderline personality disorder could accurately detect borderline personality disorder in adolescence. It helped people intervene and treat it earlier to slow the progression of borderline personality disorder. This study focused on reviewing previous research on cultural differences, detection, prevention, and intervention in adolescents with borderline personality disorder. Cultural differences like different social norms or traditions influence individual identity and interpersonal relationships, which are non-negligible components of the period of adolescence that could induce borderline personality disorder if adolescents have issues with those parts. People need to be aware of the symptoms to intervene in borderline personality disorder in adolescents through multiple treatments with an appropriate plan and management, which should focus on psychotherapy, like dialectic behavioural therapy, supportive psychotherapy, and Mentalization-based therapy.

Understanding the Development of Borderline Personality Disorder from an Evolutionary Perspective

Patients with borderline personality disorder (BPD), a type of personality disorder, typically experience extreme mood swings, leading to unstable personal relationships, severe morbidity, and high social costs. Given that natural selection is known to optimize survival gains, how are there still individuals whose ability to manage social relationships is broken, maintain personal relationships, and sustain survival? The current study proposes two possible hypotheses to answer this question. Hypothesis A predicts that mental disorders are caused by an inevitable genetic mutation that affects human behaviors. In this case, there were no adaptive designs of BPD. Hypothesis B suggests that BPD may be once helpful to ones survival in some environments, leading to its gene adaptation. If this hypothesis holds, BPD can be found in certain circumstances more commonly than others. The study concluded that the BPD prevalence rates found between different ethnic groups (Asian, Hispanic, and Caucasian) are inconsistent, suggesting that there was an adaptive purpose for developing BPD. It also implied that the aspects attributed to the variety of BPD prevalence rates among societies might be found based on different social values. Further investigations are needed to investigate the adaptive mechanisms of BPD to help with BPD diagnoses and treatments for BPD patients in various cultural settings.

The Effectiveness Of Schema Therapy In Personality Disorders: A Systematic Review

Schema Therapy is a psychotherapy method that is increasingly popular in the psychological treatment of personality disorders. In this study, it was aimed to examine the academic studies published on the effectiveness of schema therapy in personality disorders and to evaluate the examined studies within the framework of certain criteria. In this systematic review, eleven (11) research articles were selected in accordance with the research criteria were examined. The findings obtained from the studies are presented under the titles of "Study ID, Type of Analysis, Personality Disorder Type, Assessment Tools, Findings, Conclusions". Studies conducted between 2011-2022 were included in the review. The sample of the studies included in the study consisted of cluster A, B and C personality disorders. In many studies, schema therapy clusters B and C have been found to be effective in treating personality disorders and reducing symptoms. However, in the literature, on the treatment of personality disorders is very limited in the literature. A large part of the studies is aimed at researching borderline personality disorder. For this reason, it is important for future studies to contribute to the literature on the effectiveness of schema therapy by considering other personality disorders besides borderline personality disorder in a larger clinical sample.

The Co-occurrence of Personality Disorders and Substance Use Disorders.

Despite significant negative outcomes, the co-occurrence of personality disorders (PDs) and substance use disorders (SUDs) continues to be underrecognized, and the mechanisms contributing to this co-occurrence remain unclear. This review summarizes recent work on PD-SUD co-occurrence, with a focus on borderline and antisocial PDs, general substance use patterns among those with PDs, and the association of personality traits with SUDs. The prevalence of co-occurring PD-SUD is generally high, with estimates ranging depending on the type of PD and SUD, the population assessed, and the sampling methods and measures used. Current theoretical explanations for co-occurrence include shared etiology and predisposition models, with research highlighting the importance of transactional processes. Potential underlying mechanisms include personality traits and transdiagnostic characteristics. Recent research has increased focus on substances besides alcohol, dimensional models of personality pathology, and transactional explanations of co-occurrence, but more research is needed to disentangle the nuanced PD-SUD relationship.

Negative influence of futures exposure on borderline personality disorder of futures investors

BackgroundBorderline personality disorder is a common type of personality disorder, and its patients have difficulties in emotional regulation and self-perception. As a high-risk financial activity, future investment may cause investors to produce huge financial and emotional pressure, resulting in negative emotional impact.Subjects and MethodsThe study selected 100 investors who experienced futures explosion within a year as the experimental group, and 100 investors who did not experience futures explosion as the control group. The Borderline Personality Disorder Questionnaire was used to assess the borderline personality disorder traits of the investors and again to classify them into high and low borderline personality disorder trait groups. SPSS software was used for data analysis, and an independent sample t-test was used to compare the difference of ESI scores between different groups.ResultsThe results of the study showed that the mean borderline personality disorder trait score of the experimental group was 28.5±5.7, while the mean ESI score of the control group was 24.2±4.9. Independent sample t test showed that the score of BPD trait in the experimental group was significantly higher than that in the control group (t = 5.73, P < 0.001). The percentage of investors with borderline personality disorder trait scores higher than the standard scores reached 75% in the experimental group.ConclusionsThe results show that the number of future bursts will significantly deepen the trait of borderline personality disorder and depression of investors.

Analisis Kasus Gangguan Kepribadian Avoidant Personality Disorder pada Siswa di MTs Nurul Aman

Personality disorder is a mental illness that makes individuals experience mistakes about their own behavior patterns related to interpersonal relationships. This mistake will prevent individuals from adjusting to their internal and external demands. Individuals with this personality disorder feel isolated or unacknowledged by people who are believed to not love them. Types of personality disorders according to Cluster C where individuals with this personality disorder show excessively anxious or fearful behavior include avoidant, dependent, obsessive-compulsive personality disorders. MTs Nurul Aman student with a history of the case of R who has avoidant personality disorder caused by R short or unclear speech that makes him an individual of inferiority. The behavior change that can be made to help this client is to use the Cognitive Behavior Therapy (CBT) approach.

Through Bowlby and Mahler towards Masterson: from child study to adult healing

The focus on human personality and its disorders—extending beyond symptom-atology and inner fantasy to concern with the whole self and relationship—has created a paradigm shift in psychoanalysis. Detailed observation and study of growing children and their mothers lent impetus to this change, and gave increased relevance to the object relational concept of the infant’s psychic internalisation of external perception. A leading figure in the treatment of personality disorder, James F. Masterson drew much from Margaret Mahler’s developmental constructs and John Bowlby’s conceptualisations of attachment. In particular, Masterson’s work built upon Mahler’s subphases of separation–individuation in order to define the progression of unmet psychic needs underlying the schizoid, narcissistic, and borderline personality disorders. Relatedly, Masterson’s approach implemented Bowlby’s formulations of secure mother–child attachment in shaping an effective therapeutic alliance. Following Bowlby, Masterson emphasised the patient’s developmental need for a steadfast therapeutic frame and therapeutic respect for the despair suffered by patients coming to grips with the early trauma of insecure attachment. Extensive illustrations of Masterson’s specific interventions with the different personality disorder types are included.

G-FORCE: the effectiveness of group psychotherapy for Cluster-C personality disorders: protocol of a pragmatic RCT comparing psychodynamic and two forms of schema group therapy

BackgroundCluster-C personality disorders (PDs), characterized by a high level of fear and anxiety, are related to high levels of distress, societal dysfunctioning and chronicity of various mental health disorders. Evidence for the optimal treatment is extremely scarce. Nevertheless, the need to treat these patients is eminent. In clinical practice, group therapy is one of the frequently offered approaches, with two important frameworks: schema therapy and psychodynamic therapy. These two frameworks suggest different mechanisms of change, but until now, this has not yet been explored. The purpose of the present G-FORCE trial is to find evidence on the differential (cost)effectiveness of two forms of schema group therapy and psychodynamic group therapy in the routine clinical setting of an outpatient clinic and to investigate the underlying working mechanisms and predictors of outcome of these therapies.MethodsIn this mono-centre pragmatic randomized clinical trial, 290 patients with Cluster-C PDs or other specified PD with predominantly Cluster-C traits, will be randomized to one of three treatment conditions: group schema therapy for Cluster-C (GST-C, 1 year), schema-focused group therapy (SFGT, 1.5 year) or psychodynamic group therapy (PG, 2 years). Randomization will be pre-stratified on the type of PD. Change in severity of PD (APD-IV) over 24 months will be the primary outcome measure. Secondary outcome measures are personality functioning, psychiatric symptoms and quality of life. Potential predictors and mediators are selected and measured repeatedly. Also, a cost-effectiveness study will be performed, primarily based on a societal perspective, using both clinical effects and quality-adjusted life years. The time-points of assessment are at baseline, start of treatment and after 1, 3, 6, 9, 12, 18, 24 and 36 months.DiscussionThis study is designed to evaluate the effectiveness and cost-effectiveness of three formats of group psychotherapy for Cluster-C PDs. Additionally, predictors, procedure and process variables are analysed to investigate the working mechanisms of the therapies. This is the first large RCT on group therapy for Cluster-C PDs and will contribute improving the care of this neglected patient group. The absence of a control group can be considered as a limitation.Trial registrationCCMO, NL72826.029.20. Registered on 31 August 2020, first participant included on 18 October 2020.

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

The ICD-11 has adopted a classification of Personality Disorders (PD) that abolishes the established categorical PD types in favor of global severity classification with specification of individual trait domains. To facilitate and guide this profound transition, an overview of current research on empirical associations between established PD types and ICD-11 trait domains seems warranted. We identified a total of 9 relevant studies from 2018 to 2022, which were based on both clinical and community samples from U.S., China, Brazil, Denmark, Spain, Korea, and Canada. The patterns of associations with ICD-11 trait domains were systematically synthesized and portrayed for each PD type. Findings overall showed expected and conceptually meaningful associations between categorical PD types and ICD-11 trait domains, with only few deviations. Based on these findings, we propose a cross-walk for translating categorical PD types into ICD-11 trait domains. More research is needed in order to further guide continuity and translation between ICD-10 and ICD-11 PD classification in mental healthcare, including facet-level ICD-11 trait information. Moreover, the nine reviewed studies only relied on self-reported ICD-11 trait domains, which should be expanded with clinician-rated trait domains in future research. Finally, future research should also take ICD-11's essential PD severity classification into account.

Individual psychotherapy for cluster-C personality disorders: protocol of a pragmatic RCT comparing short-term psychodynamic supportive psychotherapy, affect phobia therapy and schema therapy (I-FORCE)

BackgroundCluster-C personality disorders (PDs) are highly prevalent in clinical practice and are associated with unfavourable outcome and chronicity of all common mental health disorders (e.g. depression and anxiety disorders). Although several forms of individual psychotherapy are commonly offered in clinical practice for this population, evidence for differential effectiveness of different forms of psychotherapy is lacking. Also, very little is known about the underlying working mechanisms of these psychotherapies. Finding evidence on the differential (cost)-effectiveness for this group of patients and the working mechanisms of change is important to improve the quality of care for this vulnerable group of patients.ObjectiveIn this study, we will compare the differential (cost)-effectiveness of three individual psychotherapies: short-term psychodynamic supportive psychotherapy (SPSP), affect phobia therapy (APT) and schema therapy (ST). Although these psychotherapies are commonly used in clinical practice, evidence for the Cluster-C PDs is limited. Additionally, we will investigate predictive factors, non-specific and therapy-specific mediators.MethodsThis is a mono-centre randomized clinical trial with three parallel groups: (1) SPSP, (2) APT, (3) ST. Randomization on patient level will be pre-stratified according to type of PD. The total study population to be included consists of 264 patients with Cluster-C PDs or other specified PD with mainly Cluster-C traits, aged 18–65 years, seeking treatment at NPI, a Dutch mental health care institute specialized in PDs. SPSP, APT and ST (50 sessions per treatment) are offered twice a week in sessions of 50 min for the first 4 to 5 months. After that, session frequency decreases to once a week. All treatments have a maximum duration of 1 year. Change in the severity of the PD (ADP-IV) will be the primary outcome measure. Secondary outcome measures are personality functioning, psychiatric symptoms and quality of life. Several potential mediators, predictors and moderators of outcome are also assessed. The effectiveness study is complemented with a cost-effectiveness/utility study, using both clinical effects and quality-adjusted life-years, and primarily based on a societal approach. Assessments will take place at baseline, start of treatment and at 1, 3, 6, 9, 12, 18, 24 and 36 months.DiscussionThis is the first study comparing psychodynamic treatment to schema therapy for Cluster-C PDs. The naturalistic design enhances the clinical validity of the outcome. A limitation is the lack of a control group for ethical reasons.Trial registrationNL72823.029.20 [Registry ID: CCMO].

Analysis of the Relationship between Higher-Order Factor Structure of Personality Disorders and the Five-Factor Model of Personality.

The growing body of evidence on the dimensional classification of personality disorders (PD) has resulted in its acceptance in the ICD-11 classification, which abolished categories and retains only a general description of PD. Specifying the type of PD is optional, and the suggested domains represent maladaptive variants of the five-factor model of personality (FFM). The aim of our study was to explore the existence of a joint structure between maladaptive and normal personality traits, and to investigate how these structures are integrated. The study included 223 patients who had been diagnosed with PD and completed the Structured Clinical Interview for DSM-5 Personality Disorders and the NEO Personality Inventory-Revised (NEO-PI-R). To determine the degree of overlap between PD domains and NEO PI-R scales, a canonical analysis of covariance was conducted. Our findings showed a relationship between the internalizing PD spectrum (consisting of avoidant, dependent, and borderline traits with detached and anankastic traits) and high neuroticism, low conscientiousness, and moderately low agreeableness and extroversion, suggesting the existence of a broad personality disorder factor. However, the internalizing dimensions exhibited a more pronounced effect within this construct. Furthermore, we identified a second function that demonstrated a link between the externalizing PD spectrum (including narcissistic, histrionic, and antisocial traits) and high extraversion, high openness, and low agreeableness, suggesting the existence of an externalizing factor. Overall, our findings provide evidence for a joint structure of maladaptive and normal personality traits in a sample of personality disorders and emphasize the importance of integrating the FFM model in PD evaluation in clinical practice, suggesting that differentiating between major subgroups could assist in adjusting therapeutic approaches.

Feasibility and preliminary outcomes of intensive mindfulness and yoga on prisoners with personality disorders: A randomised controlled preliminary study

This study was the first to test the feasibility of mind-body interventions with a randomised control research design in a sample that contains all ten types of personality disorders, and the first to provide a preliminary evaluation of responses using a combination of psychological, genomic, neural, and behavioural measures. Thirty prisoners with personality disorders were recruited within a clinical unit of a high security prison and assigned to a mindfulness intervention (n=10), a yoga intervention (n=10), or a wait-list control group (n=10). Both mindfulness and yoga interventions were held simultaneously and lasted three hours per day on five consecutive days. At baseline and after the intervention, we measured inflammation-related gene expression through venous blood; attention with a cognitive task; event-related potentials (ERPs) with EEG; and stress, emotion regulation and mindfulness with questionnaires. Here we show that recruitment and dropout rates were satisfactory, and data collection was successful despite its length and complexity. The only exception were blood samples where 60% of participants refused to give blood, but this was expected because 47% of recruited participants had a diagnosis of paranoid personality disorder. Unexpected difficulties occurred when participants did not fully adhere to randomisation procedures, and a riot took place during the final day of the interventions. This study was underpowered to detect changes on primary or secondary outcome measures, but despite that 80% of examined inflammation-related genes showed medium and large effect sizes suggesting this as an important outcome measure in future studies. Minor adjustments to the study design are necessary before a larger scale study can be conducted to precisely determine the effects of mindfulness and yoga as an additional treatment for prisoners with personality disorders.

A Multi-View Learning Approach for Detecting Personality Disorders Among Arab Social Media Users

Multi-view fusion approaches have gained increasing interest in the past few years by researchers. This interest comes due to the many perspectives that datasets can be looked at and evaluated. One of the most urging areas that require constant leveraging with latest technologies and multi-perspective judgments is the area of psychology. In this article, a novel multi-view fusion model using deep learning algorithms is presented to detect popular types of personality disorders among Arab users of the Twitter platform in an expert-driven fashion, based on the descriptions of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. To the best of our knowledge, the work presented is the first of its kind with no publicly available datasets that report statements around personality disorders in the Arabic language, and thus we created AraPerson, a dataset that consists of 8,000 textual tweets coupled with 8,000 images that prescribe mental statuses for a total of 150 users collected with regular expressions generated under the supervision of domain experts. The dataset was fed into a baseline multi-view model by combining a CNN model with a Bi-LSTM model to detect two types of popular personality disorders by analyzing textual and visual posts on 150 user profiles. The experiments were followed with fusing the DenseNet model with the Bi-LSTM model, experimenting with the effect of using concatenation, addition, and multiplication methods for vectors’ combination. The work presented in this article is unprecedented, specifically in a controversial area such as personality disorders detection among Arab communities. The best reported accuracy is 87%, which is quite promising, as the two types of personality disorders investigated are highly overlapping.

Schizoid personality disorder: a rare type

Schizoid personality disorder is a rare type of personality disorder that is characterized by restricted range of expression of emotions such as emotional coldness, detachment or flattened affectivity to almost each and everything in daily and natural activities. This was a case report about a 30 year old male from a rural area who presented with the complaints of being self absorbent, slothful, reluctant with self-laughing, self-muttering and odd behavior, having little interest in emotional reaction with poor social interactions and no interest in earning or pleasurable activities. On mental state examination his mood was found to be euthymic with restricted affect; decreased rate and rhythm of speech with impairment of judgement, abstract and insight. Other medical causes of such conditions were excluded. In addition to pharmacological treatment, psychological interventions were exercised and considerable improvement was noticed.

Sistem Pakar Skrining Gejala Gangguan Kepribadian Ambang Menggunakan Metode Certainty Factor

Borderline Personality Disorder is a type of personality disorder characterized by an overall unstable personality pattern, excessive impulsivity, which often confuses sufferers with their own identity. An expert system is a system developed to assist in making decisions on a particular problem. This expert system aims to help screen symptoms of borderline personality disorder and provide solutions to relieve these symptoms. The method used by the expert system is the certainty factor. The expert system development stage uses the waterfall method and uses the PHP programming language. The results of this study are in the form of an accuracy value of 80% with test data of 10 people, these results are obtained by comparing the results of experts with the results of the system that has been designed
