What are the overlaps with personality and clinical psychology?
- Both focus on individual differences
- Both see critical role for assessment
- Mental health issues occur in context of personality.
- Some maladaptive forms of personality are thought of as disorder
What are the 3 ways personality relates to mental health issues and disorder?
- Vulnerability
- Personality disorder
- Other personality-related disorder
What is vulnerability?
People differ in susceptibility to mental health issues and disorders
- Genes
- Environmental stress
- Personality
Does one factor often work alone?
No, genetic effects operate via personality
- Genetic effects require environmental contribution
- Environmental effects require genetic vulnerability
Describe the diathesis-stress models
Most mental disorders involve the combined action of a personality vulnerability (‘diathesis’) and environmental stress.
- No disorder without diathesis
- No expression of diathesis without stress
- Both diathesis & stress vary by degrees
- Level of stress required to trigger disorder depends on degree of diathesis
Describe stress in the context of the diathesis-stress model
Stress may come in different forms
- Traumatic experiences
- Major life changes (including positive)
- Accumulation of ‘hassles’ (one thing after another)
Some diatheses may require specific types of stressor
- e.g., relationship- or achievement-related
Describe the diatheses specific for depression
Dependency (interpersonal sensitivity)
- Susceptibility to interpersonal stressors
Autonomy (personal achievement)
- Susceptibility to achievement stressors
Self-criticism
Pessimistic attributional style
- Internal = low self-esteem
- Stable = hopelessness
- Global = helplessness
Describe the diatheses specific for schizophrenia
Schizotypy
- Social anhedonia
- Physical anhedonia
- Perceptual aberration
- Magical thinking - watered down delusions
This diathesis may be typological
- Non-schizotypes may be at zero risk of schizophrenia (a subject of ongoing debate in the literature).
What are some schizotypy survey example items?
Social anhedonia
- “When someone else is depressed it brings me down also” (reverse scored)
Physical anhedonia
- “One food tastes as good as another to me”
Perceptual aberration
- “I have felt as though my head or limbs were somehow not my own”
Magical thinking
- “If reincarnation were true, it would explain some unusual experiences I have had”
What are some other examples of diatheses?
Anorexia nervosa
- Perfectionism
Bipolar disorder
- Hypomanic temperament
Obsessive-compulsive disorder
- Thought-action fusion
Panic disorder
- Anxiety sensitivity
What are the illustrative items for other diatheses examples (see card 10)
Perfectionism
- “If I do not set the highest standards for myself I am likely to end up a second-rate person”
Hypomanic temperament
- “I am frequently so hyper that my friends kiddingly ask me what drug I’m taking”
Thought-action fusion
- “Having a bad thought is almost as sinful to me as a bad action”
Anxiety sensitivity
- “It scares me when I feel faint”
Describe personality disorders
Some personality attributes can be extreme, inflexible & maladaptive
These can be diagnosed as ‘personality disorders’

Describe avoidant personality disorder
A pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation, beginning by early adulthood and present in a variety of contexts
Describe the 7 traits (having 5 or more of these can indicate having it) avoidant personality disorder
- Avoids occupational activities that involve significant interpersonal contact because of fears of criticism, disapproval, or rejection.

Define Dissociative Identity Disorder
Controversial diagnosis (Previously Multiple Personality Disorder, now ‘Dissociative Identity Disorder’: DID)
≥ 2 distinct personalities that switch
- 1 host personality
- 1 or more ‘alters’Alters may differ in many ways
Detail A-E from the DSM-5 for DID
A. Disruption of identity characterized by two or more distinct personality states, which may be described in some cultures as an experience of possession. The disruption in identity involves marked discontinuity in sense of self and sense of agency, accompanied by related alterations in affect, behavior, consciousness, memory, perception, cognition, and/or sensory-motor functioning. These signs and symptoms may be observed by others or reported by the individual.
B. Recurrent gaps in the recall of everyday events, important personal information, and/or traumatic events that are inconsistent with ordinary forgetting.
C. The symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
D. The disturbance is not a normal part of a broadly accepted cultural or religious practice.
Note: In children, the symptoms are not better explained by imaginary playmates or other fantasy play.
E. The symptoms are not attributable to the physiological effects of a substance (e.g., blackouts or chaotic behavior during alcohol intoxication) or another medical condition (e.g., complex partial seizures).
What are 3 dissociative experience sample items?
Amnesia
- Some people have the experience of finding themselves in a place and having no idea how they got there.
- Some people have the experience of finding new things among their belongings that they do not remember buying.
Depersonalization/derealization
- Some people sometimes have the experience of feeling as though they are standing next to themselves or watching themselves do something as if they were looking at another person.
- Some people sometimes have the experience of feeling that other people, objects, and the world around them are not real.
Absorption
- Some people find that they sometimes sit staring off into space, thinking of nothing, and are not aware of the passage of time.
- Some people sometimes find that they become so involved in a fantasy or daydream that it feels as though it were really happening to them.
What is the dominant theory for DID?
People with DID usually report suffering extreme trauma
They also tend to score high on ‘suggestibility’ (to hypnosis)
‘Dissociation’ as auto-hypnotic defence in which consciousness is ‘split’ during traumatic stress
- Dissociation = ‘internal avoidance’ or compartmentalization.
Patients become rehearsed and skilled in this defence & construct alter personalities to deal with complexities and threats of life experience
What is the sociocognitive theory for DID?
The disorder may not be a naturally occurring splitting or fragmentation of the personality.
It may instead be caused by therapists and culture.
Therapists (poorly skilled) inadvertently may use leading questions in suggestible, unstable people may create apparently distinct personalities: iatrogenic.
Culture sanctions this manner of expression of psychological distress through creative mass media and news.
Treatment implications involve ignoring post-traumatic symptomatology.
