Q

What is test-retest reliability

A

The extent to which people receive similar scores across time after taking a test / clinical observation

Q

What is alternate-form reliability and why may it be used?

A
  1. The extent to which two forms of the same test are consistent over time
  2. researchers may use different tests of the same dimension to avoid first-order/repetition effects in participants/clients)

Q

What is internal consistency reliability + example?

A

Where items on a test are related within the questionnaire, eg. the scores should correlate with one another if they adequately measure a disorder

Q

Who started ideas about clustering syndromes as disorders?

A

In psychiatry, Emil Kraepelin in 1883

noticed groups of symptoms of behaviour clustered together as a syndrome, he hypothesised each to have their own cause, first introduced explanations for dementia praecox (schizophrenia) and manic-depressive psychosis (bipolar disorder)

What are some markers of the DSM-5?

A
  • Specific markers for diagnosis and good operational definitions and descriptors of a disorder,

Uses clinical discretion + empirical evidence and good reliability

The DSM-5 considered different types of information affecting diagnosis, such as life-span developmental approaches, gender, culture, physical health, disability and diagnostic assessment instruments
Field studies were done to evaluate changes made to DSM-5

Q

What are the arguments for and against including broad syndromes across cultures or to differentiate cultural concepts?

A
  1. Some argue for a cross-cultural approach, pointing to similarities between cultural concepts of distress and DSM diagnostic criteria
  2. Others argue that cultural concepts of distress are central and that ignoring them may lead to underestimation of psychiatric disorder prevalence

Q

What are the 2 main criticisms of the DSM?

A
  1. Too many diagnoses

DSM-5-TR even includes the category “unspecified,” disorders which is to be used when a person meets many but not all of the criteria for a diagnosis

  1. Too many disorders? Could some be grouped/clustered given high comorbidity rates (45%) is the norm?

HOW is caffeine intoxication disorder as a mental illness? Or acute stress disorder?

Q

What are 2 reasons why might it be a good idea to cluster disorders together?

A
  1. Many disorder have high comorbidity rates often occur because symptoms are present in multiple diagnostic categories, eg. social withdrawal, repetitive behaviours
  2. disorders often share risk factors and treatment plans in common, eg. SSRIs, genetic vulnerability to multiple disorders

A
  1. Describe - To give a description to accommodate signs and syndromes within a social construction in a categorisation system
  2. Find causes - into origins and triggers of behaviours

Q

What are 4 disadvantages to receiving a diagnosis as a patient?

A
  1. A diagnosis is descriptive not an explanation, underlying processes may be overemphasised
  2. Labels can cause stigma and discrimination and affect self-concept
  3. Overlooks lived experience “client with x” not “x person”

Decisions need to have both high sensitivity and high specificity rate to avoid false positives and negatives, eg. think of Hit/miss model

40
Q

What is a categorical classification for disorders and what does it assume?

A

I have disorder or do not have disorder (one threshold to become ‘diagnosable’ - it is a dichotomy and assumes all people are at one of two of those levels

41
Q

What are the two disadvantages of a categorical classification?

A
  1. It has little evidence to support DSMs diagnostic threshold for disorders
  2. Many people at ‘subthreshold’ level still experience high distress and low functioning
42
Q

What are the 2 advantages of a categorical classification?

A

Categorical classification is good to demarcate disorders to make

  1. differential disorders - comorbidity occurs often but doesn’t always mean people have an overlap in disorders
  2. appropriate treatment -
43
Q

What is a dimensional classification?

A

= the degree to which an entity is present, from 1-10

44
Q

What are the 2 advantages of a dimensional classification?

A
  1. Measures both the presence and the severity of a disorder - indicating pathways to appropriate treatment and resources
  2. It includes both subthreshold and severe cases of mental illness
  3. Considers the variability across the population
45
Q

How is the DSM adopting a more dimensional approach in 2 ways?

A
  1. Emerging models and measures contain a dimension approach, but all main disorders still have a categorical approach
  2. The DSM provides severity rates for nearly all disorders, to distinguish acute, early signs, reactive or clinical rates of a disorder
46
Q

What are transdiagnostic criteria?

A

Transdiagnostic criteria are criteria that across disorders

47
Q

What does a disorder with a large number of transdiagnostic criteria indicate?

states that biological responses to sustained high levels of stress cause three phases: alarm reaction, resistance, and exhaustion

75
Q

How do tests like the MMPI use validity designs to account for limitations with self-reporting?

A

Validity designs to detect over or underreporting symptoms or experiences -

  • including statements like “i read newspaper editorials every single day” to detect if people are over reporting behaviours that they are unlikely to do in real life

divide sequence behaviours into various parts within a learning framework

behind a one-way mirror for researchers

81

= asks people to monitor and record their own behaviour and responses of daily experience to collect data on different people, emotions, stressors, coping behaviours and thoughts

Example - Ecological Momentary Assessment (EMA) a text message alert many times a day

82
Q

Translations challenges to tests

A
  1. Translations - Need to use real translators, back translating and testing with many native speakers to ensure the test is similar and measures the same things as the original
  • guidelines are not always followed of test transitions and cultural biases can cause clinicians to over/underestimate mental health problems, this can be reflected in different rates of diagnosis across cultures
83
Q

How does cultural perception of emotion impact clinical presentation?

A

Misunderstandings about culture and emotion, despite asian cultures want to feel low-arousal positive emotions like calmness and contentment, over Americans desire for excitement

an asian may appear to have dysthymia/anhedonia when they express emotions and value different emotions

84
Q

What is the link between the ideal vs. current self in depression?

A

Depression is more likely to occur when there is a greater discrepancy between what one wants to feel and what one currently feels— that is, a discrepancy between ideal and current affect—is associated with depression

85
Q

What is more important in genetics? - sequencing or individual genes

A

sequencing genes (20-25000 genes)

86
Q

What is heritability?

A

the extent to which variability in behaviour in a population is accounted for through genetics from 0.0-1.0

87
Q

Can you discuss heritability at individual or group level?

Only at a group level, eg. ADHD population is found to be 70% attributed to genetics

88
Q

What is shared vs non. shared environment?

A

things family members have in common vs. things family members don’t have in common

89
Q

What is the link between heritability and SES?

A
  1. low SES found 60% of IQ is attributed to environment,
  2. high SES found 40% of IQ is attributed to environment

shows how impoverished environment has a bigger influence on IQ than affluent one

90
