Treatment for schizotypal

Treatments are underdeveloped.

Antipsychotics and psychotherapeutic intervention (CBT, cognitive remediation, social skills) produce mixed results

Q

General ASPD risk factors

A

50% appears to be genetic variance (specific genes actually confer general risk of developing externalizing behaviour broadly).

These broad vulnerabilities are shaped into an ASPD-specific presentation overtime via interactions with environmental risk factors (child adversity, prenatal complications)

Q

How do we conceptualize personality disorders?

A

PD’s are associated with maladaptive, extreme or overly rigid traits.

Dimensional frameworks like the FFM that are based on
1) personality traits are continuously distributed in population
2) personality pathology reflects extreme variants of typical personality traits

Categorical framework like DSM assumed manifestation of PD was through a number of discrete disorders defined by a polythetic criteria set (diagnosed with only a subset of symptoms w/o meeting all criteria)
Ex: meeting 4 out of 8 list of symptoms - leaving room for variability in individual disorder presentation.

PD revision in DSM 5 - alternate framework in section III

Q

Limitations on diagnostic model of PD’s (challenges presented in conceptualization)

A

Cultural issues:
Research is often on WEIRD samples and even when research does focus on underrepresented groups they do so with one non-majority group at a time, therefore any moderating effects or intersectional identities (such as combined marginalized status as a result fo sexual and ethnic identity) on PD development are largely unknown

Gender Issues:
Effects if internalized homophobia may resemble the patterns of stormy relationships that characterize BPD. But because gender identity and sexual orientation are not typically questioned we risk increased misdiagnosis for these communities.

Comorbity:
Co-occurance of among personality disorders is excessive, but this may result from significant redundancy of PD criteria. More study in etiological factors are needed to understand why some co-occur at an elevated rates.

Reliability:
-Base rates of these disorders are low and epidemilogical research is limited, thus studying these conditions is limited.

-PD’s are associated with a # of inaccurate and harmful stereotypes

-PD’s long considered untreatable and to this day few disorders have empirically supported treatments

Hypervigilence, inclined to attribute negative events to outside sources - specifically another person

17
Q

Treatment for PPD

Critically understudied. Limited research on interventions that target paranoia as a symptom of other disorders.

18

- Restricted range of emotional expression in social settings
- Reduced sensitivity to pleasure (bodily, sensory, interpersonal)

6) Displaying emtoional coldness, detacthment, or flat affect
7) Taking pleasure in few, if any, activities

19
Q

Treatment for Schizoid

A

Evidence based treatments are lacking.

Condition is largely related to social isolation so treatment is rarely seeked and if it is it is usually about other concerns (depression)

20
Q

What are the key characteristics of Shizotypal Disorder

A

Eccentric behaviour - odd mannerisms
Cognitive and perceptual distortions(believing clairvoyance, hearing voice whisper one’s name)
Impaired interpersonal functioning
Transient psychotic symptoms - lasting minutes to hours (lower in severity and frequency than a psychotic disorder)
Features groups in 1) interpersonal 2) Cognitive 3) disorganization

5 of 9 symptoms:
COG:
1) non-delusional ideas of reference
2) odd beliefs and magical thinking
3) paranoia
4) unusual perceptional or somatic experiences

IP::
5) lacking close friends
6) persistent social anxiety even with familiarity
7) Constricted or inappropriate affect

DISORGANIZED:
8) odd/eccentric behaviours and appearance
9) odd thinking/speech

21
Q

Treatment for schizotypal

A

Underdeveloped.

Studies examining psychotropics focus on antipsychotics and produce mixed results - anxiety and paranoia seem most responsive.

Psychotherapeutic results are mixed.

22
Q

What are the key characteristics of Narcisstic Disorder

A

Lac of empathy
Grandiose sense of self importance
Socio-emotional dysfunction
Significant interpersonal problems

Diminish importance of failure and avoid responsibility
Seek out high status individuals
High achieving
Prosocial behaviours when result in personal gain

23
Q

Treatment of Narcisstic Disorder

A

Challenging to treat due to consider variabiity in presentation, highs rates of comorbidity, poor insight and high dropout rates.

Individuals with NPD are more likely to seek out treatment for co-occuring issues (substance use, mood disorders) and IP.

Evidence based treatments are very much needed, guidelines are lacking. But some researchers have proposed psychodynamic-oriented therapies, scheme therapy, CBT and DBT

24
Q

What are the key characteristics of Histrionic

A

Remains less studied than most PD’s.

-Exaggerated emotional expressions
-Excessive attention-seeking behaviours
-Difficulty developing and maintaining IP intimacy and perceive relationships to be more intimate than they are
- DSM -displays provactive or sexually seductive behaviours in socially inappropriate social contexts

25
Q

Treatment of Histrionic

A

2 single studies found significant reductions in symptoms after functional analytical psychotherapy - a theraputic approach using behavioural principles like shaping through positive reinforcement to treat presenting problems

Another study showed CBT for violence reduction

26
Q

What are the key characteristics of Anti Social

A

Disregard for and violation of others’ rights.

Aggression
Impulsivity
Poor self regulation
May lack remorse for wrongdoings

Irresponsibility

ASPD features are understudied and poorly understood

27
Q

What are the key characteristics of Avoidant PD

A

Maladaptive avoidance of social experiences, driven by perceptions of inadequacy and extreme sensitivity to negative evaluation and rejection.

Anxiety, fear, low self esteem = core features

Tend to be colder, more submissive

A interpersonal disorder. Associated with impairment in major life domains. Low self efficacy, mental distress, lower education achievement, lower income.

Functional impairment among highest or all PD’s.Co-occuring with Dependent PD.

28
Q

Treatment for APD

A

Treatments with most empirical support are CBT, schema therapy (and to lesser extent psychodynamic therapies).

CBT targets maladaptive beliefs and incporporates social skills training as well as beh. experiments to challenge fears.

Group CBT shows efficacy with improving fears of negative evaluation

Social schema - 80% recovery rates copared with treatment as usual.

29
Q

What are the key characteristics of Dependant PD

A

Submissive attitudes and behaviours
Extreme reliance on others
Maladaptive persuits of IP connection

BEH. Features:
-Clinging to others
-Frequent reassurance seeking
-Inappropraite bids for help (asking others to make every day decisions)

Patterns of passivity and accomodation of others, however not always passive and submission, bc DPD is also tied to perpetuating aggression and violence.

They report more general health problems - seek out medical advice, high treatment adherence and low drop out

30
Q

DPD treatment

A

Individuals with DPD and other cluster C PD”s show greater treatment progress when recieving short term care (6 months or less).

Some positive evidence with CBT, short-term dynamic therapy and relational therapy.

One study found evidence for adapted mindfulness for reducing dependency related problems

2 RCT’s showed clarification-oriented psychotherapy (COP) effective for reducing symptoms and increasing self efficacy

32
Q

Treatment of OCPD

A

Empirical evidence limited.

Preliminary evidence for certain psychotropic med’s (carbamazepine; anti convulsant, fluvoxamine; SSRI)

Pharmacological and psychological RCT’s are lacking

33
Q

Difference between schizotypal and schizotypy

A

Terms are often used interchangeably. The two constructs overlap significantly however not all your have schizotypy will develop schizotypal PD.

Schizotypy is a person with genetic liabilty for schizophrenia, but who may or may not progress to full blown psychotic illness.

34
Q

Why are ASPD individuals more likely to engage in aggressive activity?

A

Due to cognitive biases, whereby ambiguous or neutral social cues are interpreted as hostile (hostile attribution bias)

35
Q

- rigidity and excessive self-control appear to be specific to OCPD

OCD:
-Egodystonic (view symptoms as problematic)
-Obsession appear to be specific to OCD
