Features of Cluster B Personality Disorders

The following elucidates a compendium of disorders falling under the Cluster B category. The foremost disorder listed is Antisocial Personality Disorder (ASPD), characterized by behaviors encompassing perilous acts towards oneself and others (, 2022). For instance, the fictional character Joker from Batman exhibits a lack of empathy alongside aggressive and erratic behavior, exemplified by laughing while engaging in criminal activities. Borderline Personality Disorder (BPD) manifests in individuals displaying combative behaviors, separation anxiety, or fear of abandonment, often accompanied by suicidal ideation (, 2022). This implies that changes in communication patterns are interpreted as a lack of love or care, leading individuals to devalue their own lives.

Histrionic Personality Disorder (HPD) is typified by egocentric behavior and superficiality in opinions (Kopf & Herron, 2021). Individuals diagnosed with HPD tend to vie for superiority by incessantly boasting about their intellect and achievements. Narcissistic Personality Disorder (NPD) is distinguished by excessive attention-seeking, a sense of superiority, grandiosity, and pervasive jealousy (Pedersen & Ditzell, 2021). Individuals with NPD often exhibit aggressive behaviors, disregarding the impact on others emotionally and physically.

Personality Disorders: Obstacles in Treatment

ASPD poses challenges in treatment due to clients’ aggression, leading to defensiveness and hostility towards therapists (Zimmerman, 2021). In BPD treatment, non-compliance with treatment plans can perpetuate chronic issues (, 2022). Individuals with HPD may deny needing help unless the disorder affects their relationships (Wint & Legg, 2017). Similarly, individuals with NPD may resist treatment, perceiving no fault in themselves and prioritizing their sense of grandiosity (Kacel, Ennis, & Pereira, 2017).

Personality Disorders: Development or Causes

ASPD may develop due to childhood abuse, environmental factors, or genetic predispositions (, 2022). Genetic and environmental influences, including childhood trauma such as sexual or physical abuse, contribute to the development of BPD (, 2022). HPD may stem from genetic predispositions or environmental factors (Kopf & Herron, 2021). Similarly, NPD can arise from environmental factors and genetic predispositions (Pedersen & Ditzell, 2021).

Personality Disorders: Treatments

Treatment for ASPD may involve Cognitive Behavioral Therapy (CBT), Contingency Management (CM), and medication (Brazil et al., 2018). BPD treatment often includes Dialectical Behavior Therapy (DBT) and CBT, with DBT considered the most effective (National Institute of Mental Health, 2022). Psychotherapy is effective in treating both HPD and NPD (Kopf & Herron, 2021; Kacel et al., 2017).
