Subcategories of People with BPD
People with the same BPD diagnosis can act quite differently. Researchers have been trying to categorize them for decades. One "real world,” subjective way is to divide them into three groups:
- Lower-Functioning/Conventional
- Higher-Functioning/Invisible
- Combination (a mixture of both styles)
No category is "better” than the other. Each category has four dimensions: coping techniques, co-occurring mental health issues, functioning, and impact on family members.
| Mostly Lower-Functioning Conventional BPs | Mostly Higher-Functioning Invisible BPs | Combination | |
|---|---|---|---|
| Coping Techniques | Self-harm and suicidal thoughts | Criticism and blame of others far beyond the norm | Anger, rages common to both |
| Willingness to Obtain Help | Hospitalized or day/outpatient treatment | Refuses help or attends therapy only when threatened | More outpatient than inpatient |
| Co-occurring (Concurrent) Mental Health Issues | Eating Disorders, Bipolar, or others that frequently bring them into treatment | Narcissistic Personality Disorder, invisible to clinical community | Substance abuse, depression common to both |
| Functioning | Lower: May be disabled or often loses jobs | Higher: usually employed and job performance doesn’t suffer | Problems with coworkers may be common to both |
| Typical Family Member Challenges | Finding and paying for treatment; parents often overburdened; exhaustion and burn-out | Trying to convince the BP to get treatment, bewilderment, PTSD, losing confidence and self-esteem | Difficulty setting limits common to both |
