What is psychopathology?
Psychopathology includes the study of clinical descriptions, diagnosis, aetiology epidemiology, prognosis and treatment
What is a mental disorder?
is a syndrome characterised by clinically significant disturbance in an individual’s cognitive, emotion, regulation or behaviour that reflects a dysfunction in the psychological, biological or developmental processes underlying mental functioning
What distinguishes a mental disorder from normal behaviour?
Significant distress or disability and not explained through a culturally approached response or social deviance between individual and society, APA, 2013
What is reliability?
Reliability = the consistency of the measurement over time
What is inter-rater reliability?
the degree to which 2 independent observers agree on a clinical observation
What is test-retest reliability
The extent to which people receive similar scores across time after taking a test / clinical observation
- only tested on things not liable to change over weeks/months, eg. IQ rather than mood
What is alternate-form reliability and why may it be used?
- The extent to which two forms of the same test are consistent over time
- researchers may use different tests of the same dimension to avoid first-order/repetition effects in participants/clients)
What is internal consistency reliability + example?
Where items on a test are related within the questionnaire, eg. the scores should correlate with one another if they adequately measure a disorder
eg. scores of dry mouth and muscle tension should be higher in anxiety
What is validity?
Whether a measure measures what it is supposed to measure,
eg. whether the questionnaire accurately measures “hostility”, “anxiety”
What is criterion validity and what does it measure?
Criterion validity measures whether test scores are linked with other tests measuring the same dimension,
eg. whether anxiety scores are similar across multiple anxiety tests
What is content validity and what does it measure?
Content validity is whether a measure adequately covers the domain of interest,
Example - a social anxiety test covering anxiety in a range of different social settings
What is construct validity?
- Construct validity is about interpreting a test as a measure of a construct not observed overtly, known as an inferred attribute, eg. distorted cognition
What 4 things does construct validity want to predict?
- biological vulnerability
- triggers
- mental + physiological symptoms
- functional impairments
“A group of high school students given the same IQ test in a row” is an example of what?

Who started ideas about clustering syndromes as disorders?
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 positives of the ICD and when was it founded
- Founded in 1939 by the WHO current is the ISD-11 (2018)
- available to public at no cost
- Some conditions not in DSM, eg. C-PTSD, gaming disorder, compulsive sexual disorder
What are 2 limitations of the ICD?
- Uses guidelines not criteria, issues for reliability for diagnosis and inter-rater reliability may be affected
- Only one personality disorder present with different domain areas similar to DSM-5, eg. borderline pattern and some new, eg. negative affectivity
What are some markers of the DSM-5?
- 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
Is the multi-axial system still used?
- Diagnoses were listed on separate dimensions / axes, and required judgments on each of the five axes, forcing the diagnostician to consider a broad range of information, but is no longer used since DSM-III
What are 3 types of additions to the DSM-5?
- made arabic letters DSM-5
- New disorders
- disruptive mood dysregulation disorder
- hoarding disorder
- binge-eating disorder
- premenstrual dysphoric disorder
- gambling disorder
- prolonged grief disorder - Combined disorders
- substance abuse + dependence → substance use disorder
autism + Asperger’s → autism spectrum disorder.
Why is the DSM disorders arranged by symptoms instead of biological or genetic etiologies?
we don’t have enough info to base it on aetiology / biological reductionism
