Psychological Disorders Flashcards
What are the three Ds apart of the criteria for disorder?
- Deviance
- Distress
- Dysfunction
Describe deviance
Unusual / rare behaviour compared to most Statistical infrequency Fail to conform to societal norms BUT - rare qualities too - oppression: unique / unpopular - norms differ - some disorders quite common
Describe distress
Personal suffering
BUT
- distress about other aspects of life
- some disorders: no distress
Describe dysfunction
Significantly impairs ability to function in everyday life
Fail to meet responsibilities such as work, family and social
BUT
- other disruptions
- sometimes maintain functioning
When do behaviours become disorders?
The three Ds are not sufficient alone, need to be considered in combination. Also need to consider: - content of behaviour - sociocultural context - biological dysfunction - consequences
What is the DSM-5 (APA, 2013)?
Comprehensive diagnostic criteria
- 20 major classes of disorders (over 300 disorders)
- polythetic criteria
- Research base
Why diagnose?
Assist treatment planning
Facilitate research
Facilitate communication between professionals
Diagnosis predicts behaviour and treatment response
What are some criticisms of DSM-5?
Labelling (probably not valid)
Stigmatising (probably not valid)
Comorbidity (overlapping diagnoses)
Categorical
What other factors should a practitioner be aware of during diagnosis?
Personal circumstances (client as an individual)
Medical problems
Social/environmental problems
Overall functioning
What are the major perspectives of psychological disorders?
Biological Psychodynamic Cognitive Behavioural Humanistic Sociocultural
What is the premise of the vulnerability-stress model?
Each of us has some degree of vulnerability (ranging from very low to very high) for developing a psychological disorder, given sufficient stress.
What does vulnerability entail?
Biological - genotype, neurotransmitter irregularity, hormone irregularity, sensitive autonomic NS.
Personality - low self-esteem, extreme pessimism
Social-environmental - poverty, trauma
Cultural - overemphasis on achievement, social conditions
What does stressor entail?
An individual who as a genetic predisposition to depression, or who suffered the loss of someone early in life has the capacity to develop a disorder IF they are faced with a stressor that forces them to cope.
What are the four components to an anxiety response?
- Subjective-emotional (feelings of fear)
- Cognitive component (worrisome thoughts)
- Physiological responses
- Behavioural responses
What are the types of anxiety disorders?
Phobic disorder Panic disorder Generalised anxiety disorder Obsessive compulsive disorder Post-traumatic stress disorder
What is agoraphobia?
The excessive fear of being outside of home, being in a crowd, or in situations such as using public transport. These situations causes a fear that escape would be impossible if something distressing or embarrassing were to occur.
What is social phobia?
The individual fears situations in which they may be negatively perceived/evaluated by others
What are specific phobias?
Intense fear of a specific object, situation, or stimulus.
What is panic disorder?
Panic attacks occur recurrently and have no apparent environmental stimuli that causes them. Panic attacks can cause psychological distress and behavioural problems. It is often present with agoraphobia.
What is generalised anxiety disorder?
Chronic/ongoing state of anxiety and worry that is not attached to specific situations or objects. This disorder can interfere with daily functioning as the individual may struggle to concentrate, make decisions and remember commitments.
What is obsessive compulsive disorder?
A disorder in which people feel compelled to act in a rigid, repetitive way to reduce their anxiety or distress. Results in behaviours such as compulsive cleaning, washing checking, hoarding, etc.
What is the difference between an obsession and a compulsion?
Obsessions are cognitive: repetitive and unwelcome thoughts or impulses
Compulsions are behavioural responses to these thoughts.
What is post-traumatic stress disorder?
Severe disorder that can occur in people who have been exposed to traumatic life events
What are the four clusters of symptoms of PTSD?
- Intrusion symptoms; intrusive images that force the person to relive the trauma
- Persistent avoidance of any reminds of the event
- Negative changes in cognition or mood; fear, self-blame, anger, etc.
- Changes in arousal and reactivity; sleep disturbance, poor concentration, etc.
What biological factors contribute to the development of anxiety and related disorders?
- Higher concordance rate in identical twins compared to fraternal.
- Barlow (2002) suggests that genetic vulnerability includes an over-reactive autonomic system.
- Over-reactivity of GABA (excites the neural activity in the amygdala which triggers emotional arousal).
- Low levels of inhibitory GABA could cause anxiety.
What do psychodynamic theories suggest about development of anxiety and related disorders?
- neurotic anxiety (suggested by Freud) occurs when unacceptable impulses threaten to overwhelm the ego’s defences and explode into consciousness or action.
- compulsion is a way of controlling unacceptable urges.
What is the role of learning in anxiety and related disorders?
Fear or phobias can be acquired as a result of a conditioned fear response.
Observational learning explains how people can be afraid of stimuli they haven’t experienced.
Once anxiety is learned, it may be triggered by cues; external (phobic) and internal (panic).
Negative reinforcements are in line with compulsions.
What cognitive factors influence the development of anxiety?
Maladaptive thought patterns in anxiety consist of catastrophising about the many ambiguous situations in life, turn them into threats and feel powerless to prevent/stop them.
What is David Clark’s cognitive theory of panic disorder?
Panic attacks can be triggered by exaggerated misinterpretations of normal anxiety symptoms. They feel a loss of control due to these symptoms, resulting in more anxiety and panic.
What is Taijin Kyofushu?
Japanese disorder in which people are pathologically fearful of offending others by emitting odours, blushing, staring inappropriately or even having a blemish or improper facial expression.
It is linked to the cultural value of interpersonal sensitivity in which people are discouraged from expressing negative emotions.
What is Koro?
An anxiety disorder (based in Southeast Asia) in which a man fears that his penis is going to retract into his abdomen and kill him.
What anxiety disorders spawn in Western culture?
Anorexia nervosa built off of the phobic component of getting fat has obsessive-compulsive tendencies to prevent the distress caused by gaining weight.
What are somatic symptom disorders?
Disorders involving physical complaints or disabilities that suggest a medical problem of which do not have a known biological cause and are not produced voluntarily
What is conversion disorder?
A disorder in which serious neurological symptoms, such as paralysis, loss of sensation or blindness, suddenly occur with no biological basis, sometimes the complaint is physically impossible (glove anaesthesia).
