the alternate models come from the DSM, and it doesn't include HPD - it would be diagnosed as PD-TS (Trait Specified) in this model.

if i had to guess at a HPD alternate model:

like all alternate model PDs, it would include impairments in identity, self-direction, empathy & intimacy.

HPD's examples might look like:

identity: unclear boundaries between self & others, unstable self-image & self-esteem, inability to regulate emotions

self-direction: incoherent short & long-term goals, unstable internal standards of social behaviour

empathy: difficulties understanding others' experiences, and their effects on others

intimacy: unstable connection (and desire for) with others, unbalanced mutuality in connections

in the Five Factor Model part, HPD might also be described as being high in Negative Affectivity (e.g. mood instability & intensity, insecurity, etc.) and Disinhibition (e.g. impulsivity, risk taking, etc.)

i don't think this is exclusive to SzPD. this sounds like a fear of vulnerability. being uncomfortable with vulnerability - even while wanting it - isn't a symptom specific to any disorder; it's part of everything from PTSD, personality disorders, toxic masculinity, cultural norms of being emotionally distant...

is it something that people with SzPD could experience? absolutely! here are some posts about SzPD splitting:

my post about splitting in SzPD with charts (from Wheeler's thesis)

my post on splitting in SzPD, NPD & BPD

schizotaxic's post on SzPD, NPD & OCPD's 'superiority defense mechanism'

can i have NPD and hate myself

and feel unworthy

lots and lots of confusion and denial! some examples:

they'll obviously have all the symptoms, but instead of knowing that they're attributed to trauma, parts, and dissociation, it's very confusing and many people feel like they're going crazy

amnesia is often glossed over or purposefully ignored ("i just have a bad memory", "i drink too much and it makes me forget", etc)

lots of excuses about part behaviour ("doesn't everyone act like a kid when their favourite childhood show comes on though...?")

attributing things that in hindsight are obviously DID to thinks like the supernatural, imaginary friends, religious experiences, magic, demon or spirit possession, hypnotism, an overactive imagination etc

thinking everyone has these kinds of experiences, not realising that they're not universal

attributing symptoms to other disorders (especially BPD, substance use, bipolar disorder, seizure disorders, traumatic brain injuries, psychosis) or gender dysphoria (or otherkinity/therianthropy even)

remembering only some of the trauma, but thinking that that's all of it

feeling ashamed at their strange, inexplicable behaviour, and being unable to account for it

i think it would turn identity confusion up to 100. people with BPD tend to experience identity disturbances as one or more of these four factors:

role absorption ("defin[ing] themselves in terms of a single role or cause"),

painful incoherence (distress over identity confusion),

inconsistency (an "objective incoherence in thought, feeling, and behavior")

and lack of commitment

(from Wilkinson-Ryan & Western, 'Identity Disturbance in BPD: An Empirical Investigation', American Journal of Psychiatry (2000))

if someone had BPD with comorbid DID/OSDD, we can see how these factors would be amplified and probably split among parts.

mood swings would probably also be split among parts (e.g., one part holds anger, another joy, etc.). there might be parts who specifically deal with the intense anger people with BPD can experience.

fear of abandonment probably plays into trauma (neglect, emotional and physical especially). i can imagine young parts would experience this symptom especially strongly.

parts may come into conflict over impulsivity, especially as BPD impulsivity is damaging.

emptiness may accompany dissociation, especially depersonalisation.

and of course BPD dissociation will be a much more prominent symptom with a comorbid dissociative disorder!

emotional permanence (things like not being able to remember feeling loved even though you were happily cuddling your partner an hour ago, or being angry and feeling like no other emotion exists apart from anger) is very common in BPD (and other PDs). it's why we split - it's the whole mechanism behind splitting, actually. emotions seem to only exist in the time that we're feeling them. relationships are only secure (the borderline only feels secure) when we're actively being reassured of its security. if you and your friend are fighting, you can't recall ever feeling loved and wanted by your friend and they must only hate you. cue splitting!

ways to deal with emotional permanence:

keep physical reminders of your friends' & family's love for you (photos of a trip you took together, a birthday present, etc)

keep nice texts and voice messages sent to you

come up with a list of reasons why they love you (all the nice things they do for you, etc)

practice dialectical thinking (x and y can both be true at the same time; e.g. you can be angry at yourself and love yourself at the same time)

practice other DBT skills like wise mind (keeping a balance between your emotional mind and your rational mind)

keep a diary or mood tracker - this way you can see when you've felt other emotions and remind yourself that other emotions do exist and you do experience them (good or bad)

schedule times frequently (how frequent is up to you) to keep in contact with loved ones so you have periodic reminders of their love
