The “Favorite Person” in Borderline Personality Disorder: A Content Analysis of Social Media Posts

Objective Individuals with borderline personality disorder (BPD) commonly have a favorite person (FP), whom they are heavily emotionally attached to and dependent on. This study aims to identify and illustrate the patterns of destructive FP relationships based on actual experiences described by those with BPD.Methods A data mining process was conducted using raw data collected from online communities, such as blogs and social networks. An in-depth review of the information to better understand the natural course of the FP relationship was also conducted.Results Individuals with BPD form an intense and insecure attachment toward their FP, from which they enormously suffer. FPs can be their friends, romantic or life partners, or family members. As their feelings go beyond their control, being increasingly obsessed with their FP, they make their FP gradually lose hope in continuing the relationship and want to quit trying to fulfill their needs. The relationship finally ends when the FP stops being responsible for meeting their expectations and eventually drifts away.Conclusion This study suggests that certain FPs, distinctively named Teddy Bear Person, may behave in a particular manner to increase the likelihood of the FP relationship becoming more destructive. Moreover, the rejection sensitivity model should be discussed to understand their dysfunctional interaction.

The constructs of atypical depression, bipolar II disorder and borderline personality disorder (BPD) overlap. We explored the relationships between these constructs and their temperamental underpinnings. We examined 107 consecutive patients who met DSM-IV criteria for major depressive episode with atypical features. Those who also met the DSM-IV criteria for BPD (BPD+), compared with those who did not (BPD-), had a significantly higher lifetime comorbidity for body dysmorphic disorder, bulimia nervosa, narcissistic, dependent and avoidant personality disorders, and cyclothymia. BPD+ also scored higher on the Atypical Depression Diagnostic Scale items of mood reactivity, interpersonal sensitivity, functional impairment, avoidance of relationships, other rejection avoidance, and on the Hopkins Symptoms Check List obsessive-compulsive, interpersonal sensitivity, anxiety, anger-hostility, paranoid ideation and psychoticism factors. Logistic regression revealed that cyclothymic temperament accounted for much of the relationship between atypical depression and BPD, predicting 6 of 9 of the defining DSM-IV attributes of the latter. Trait mood lability (among BPD patients) and interpersonal sensitivity (among atypical depressive patients) appear to be related as part of an underlying cyclothymic temperamental matrix.

Demystifying borderline personality: critique of the concept and unorthodox reflections on its natural kinship with the bipolar spectrum

Tending to patients with a diagnosis of borderline personality disorder (BPD) is a challenging task for clinicians due to stigma and differences in opinion within the psychiatric community. Various symptoms of BPD including affective instability, mood reactivity, and extremes of idealization are associated with challenging emotions toward patients with BPD. This observational research study utilized an adaptation of the 37-question Attitude to Personality Disorder Questionnaire (APDQ) to assess the attitudes of clinicians toward patients with BPD. This questionnaire was distributed to 139 clinicians including psychiatry attendings, psychiatry residents, registered nurses, nurse practitioners, social workers, recreation and art therapists, and psychologists who worked with patients diagnosed with BPD on an inpatient unit. Responses of participants were compared based on occupation, gender, and duration of years worked on an inpatient psychiatric unit. Results show that individuals employed in occupations under the "other health professionals" category had more positive transference (which included feelings of respect toward BPD patients along with feelings of closeness and warmth) toward patients with BPD, and nurses had an increased total score for lack of valid difficulties compared with other health professionals. When grouping by gender and duration of year spent working on an inpatient unit, there were no significant differences in the response toward patients with BPD in affective situations. Clinical implications are discussed, as well as the need for training to help improve staff attitudes toward this patient population.

This review of the descriptive literature on borderline patients indicates that accounts of such patients vary depending upon who is describing them, in what context, how the samples are selected, and what data are collected. The authors identify six features that provide a rational means for diagnosing borderline patients during an initial interview: the presence of intense affect, usually depressive or hostile; a history of impulsive behavior; a certain social adaptiveness; brief psychotic experiences; loose thinking in unstructured situations; and relationships that vacillate between transient superficiality and intense dependency. Reliable identification of these patients will permit better treatment planning and clinical research.

This study examined whether patients with borderline personality disorder and controls with other personality disorders remember their childhoods differently with respect to separation difficulties, evocative memory, temperamental factors such as frustration tolerance and mood reactivity, and onset of symptoms. Two hundred and ninety patients with borderline personality disorder and 72 with other personality disorders were assessed using an instrument to rate memories of separation difficulties, temperamental problems, and onset of symptoms before age 18. Patients with borderline personality disorder remembered more difficulties with separation between ages 6 and 17 years, more mood reactivity and poorer frustration tolerance between ages 6 and 17, and the onset of more symptoms (most prominently sadness, depression, anxiety, and suicidality) before age 18 than did patients with other personality disorders. The groups did not differ in reports of evocative memory before age 18. These results indicate that many of the features of adult patients with borderline personality disorder may initially appear during childhood and adolescence and that these features may be used to differentiate borderline from other personality disorders.

Affect dysregulation, adult attachment problems, and dissociation mediate the relationship between childhood trauma and borderline personality disorder symptoms in adulthood

Introduction: Borderline personality disorder (BPD) in adolescents is characterized by emotional dysregulation, insecure attachment, a history of stressful life events (SLEs) as well as dysfunctional parent–child interactions. The respective contribution of each of these factors on BPD affective symptoms is not yet clear. The purpose of this study is to assess the distinct impact of parental adversity and SLEs on BPD affective symptoms and the role of attachment and alexithymia in such emotional processes.Method: This study explored parental dysfunction and SLEs as predictors of affective symptoms of BPD and of attachment insecurity in BPD adolescents (n = 85) and healthy controls (n = 84) aged 13–19 years from the European Research Network on BPD. The links between adversity and BPD symptoms were also investigated by emotional dysregulation assessment, as measured by alexithymia and hopelessness.Results: Dysfunctional parental interactions were linked to affective symptoms, hopelessness, and anxious attachment in healthy controls but not in BPD. Cumulative SLEs were positively correlated with affective symptoms and avoidant attachment in the control group but negatively correlated with both these variables in BPD. Multivariate regression analysis revealed that, in BPD, affective symptoms were independent of dysfunctional parenting but depended on attachment, whereas in controls, a maternal affectionless control style directly predicted affective symptoms. Moreover, increasing numbers of SLEs reduced affective symptoms in BPD, independently of parental interactions or attachment, and were associated with growing use of operative thinking.Discussion: BPD patients showed paradoxical emotional reactions: there was no increase of hopelessness and affective symptoms with an increased parental dysfunction, but a decrease in affective symptoms and hopelessness with cumulative SLE. Two pathways arose, one involving attachment as an emotional dysregulation process for parent–child interactions and a second one for SLE, with a more direct pathway to affective symptoms, independent of attachment but dependent on early interactions, and involving alexithymia. In summary, adversity factors have distinct effects in BPD, and attachment is partly accountable for affective symptoms independently of adversity. Our results suggest that in highly insecure conditions, cumulative adversity may produce paradoxical effects, including a lesser expression of affective symptoms and hopelessness.

Borderline personality disorder (BPD) is characterized by increased mood reactivity and affective instability. Since core structures involved in emotion processing, such as the amygdala, demonstrate strong lateralization, BPD is an interesting target for laterality research. So far, a systematic integration of findings on lateralization in BPD is missing. Therefore, we systematically reviewed studies published until February 2024 in PubMed, Web of Science, and PsycInfo databases that measured hemispheric asymmetries and behavioral lateralization in patients with BPD. Inclusion criteria were (a) diagnosis of BPD and (b) results on hemispheric or behavioral asymmetries. Specifically for neuroimaging studies, hemispheres need to be assessed separately. Review articles and studies with disorders other than BPD were excluded. Risk of bias was assessed with the Newcastle Ottawa Scale for non-randomized, non-comparative intervention studies. A total of 21 studies met the inclusion criteria. Thirteen studies investigated structural hemispheric asymmetries, five functional hemispheric asymmetries, two examined handedness, and one studied hemispheric asymmetry in visuospatial attention. Overall, studies examining structural asymmetries in BPD report bilateral volume reduction in the amygdala and hippocampus but a right-sided reduction in the orbitofrontal cortex. For functional lateralization, asymmetrical de/activation patterns in the default mode network in BPD and reduced right-frontal asymmetry were evident. Also, studies indicate a trend towards increased non-right-handedness in BPD. Risk factors for BPD, such as childhood abuse, may play a crucial role in the development of structural and functional alterations. However, the generalization of results may be limited by small sample sizes and varying study designs.

We sought to determine the differential diagnostic efficiency of all DSM-IV borderline personality disorder (BPD) criteria by studying a sample of those with BPD and a contrast group with a bipolar disorder (BP). Participants were clinically assessed and assigned diagnoses based on DSM criteria - with prevalence rates and diagnostic efficiency values calculated. Fifty-three participants were assigned a BPD diagnosis, 83 a BP diagnosis, with comorbid participants excluded. The mean number of DSM BPD criteria assigned was 6.6 (SD=1.0) in the BPD group and 1.9 (SD=1.3) in the BP group. The most prevalent criterion in the BPD group was 'affective instability' (AI) (92.5%), with 'inappropriate anger' least endorsed (49%). The highest specificity criterion was 'abandonment fears', which displayed the greatest positive predictive value (PPV)=0.9, and with AI offering the lowest specificity. 'Unstable relationships' had the highest overall negative predictive value (NPV)=0.91. The highest percentage accuracy of classification was provided by 'identity disturbance' and 'abandonment fears' criteria, both 85%. The transdiagnostic nature of 'affective instability' means it is less useful for diagnostic decisions, whereas 'abandonment fears' and 'identity disturbance' offer superior diagnostic efficiency in distinguishing BPD from BP.

Childhood trauma is a major cause of borderline personality disorder. Research shows that most patients diagnosed with borderline personality disorder report unhappy or shadowy childhood experiences in psychological assessments. Attachment may be one of the important mechanisms by which childhood trauma affects borderline personality disorder. Attachment styles have a strong influence on people. People with insecure attachment styles often show distrust of others and extreme language and behaviour. This is also a core symptom of borderline personality disorder. The aim of this study was to investigate whether insecure adult attachment styles mediate borderline personality disorder as a result of childhood trauma. In addition, a secure attachment style may have a positive effect on alleviating or even treating Borderline Personality Disorder. This study will investigate this aspect. It is hoped that this research will advance researchers' understanding of the impact of childhood trauma on Borderline Personality Disorder and its mechanisms, and provide theoretical and empirical support for interventions aimed at reducing Borderline Personality Disorder caused by childhood trauma.
