The DSM-5 is the latest version of the Diagnostic Statistical Manual, which provides criteria to diagnose mental disorders.
DEFINITIONS OF ABNORMALITY-failure to function adequately means you cannot cope or complete regular tasks ie hygiene
DEFINITIONS OF ABNORMALITY- statistical infrequency means that you are part of a statistical minority, most people dont have or do what you do
DEFINITIONS OF ABNORMALITY-deviation from social norms means your behaviour is considered strange or unacceptable by others
DEFINITIONS OF ABNORMALITY-deviation from ideal mental health means that you are feeling excessively anxious or sad etc
Diathesis stress- theorists believe that genetic vulnerability and environmental stress interact to produce a disorder
Stressors can be acute or chronic
Acute stressors are short term events which cause distress e.g death of loved one
Different types of diatheses include biological predispositions such as genetics and psychological factors like personality traits
Chronic stressors are long term events which cause distress e.g poverty, abuse
Strengths of using 'Deviation from social norms' as a definition of abnormality
Allows for developmental norms
Gives a social dimension to the idea of abnormality
Looks at an individual's abnormal behaviour and seeks to protect society from it
Has a clear indication of what is considered normal and abnormal as most of us understand and are aware of social norms in our own culture
Allows society to get involved in individuals abnormal behaviour and help them, when they may not be able to seek or identify the help they need
Developmental norms
E.g. it may be normal for a 1-year-old to be carried everywhere by its parent, but this would be abnormal if it was a 50-year-old
There are limitations to using 'Deviation of social norms' as a definition of abnormality

Changes over time
Ethnocentric
Cultural differences
Individualism
This definition does not explain abnormality changing over time
Homosexuality was not removed from the ICD until the 1990s
This definition is based on western societal norms and reflects the majority, which is a white population
Cochrane (1977) found that in Britain, black people were more likely to be diagnosed with schizophrenia than white people, however, this was not in countries with a majority black population, such as Jamaica, which suggests there is a diagnostic bias
This definition does not make it clear how to deal with cultural differences in normal and abnormal behaviour
This definition does not account for those who do not conform to social norms but are not abnormal, such as those that are individualistic or eccentric in their behaviour
'Failure to function adequately' as a definition of abnormality
Observable behaviour - focuses on behaviours which can be observed in the individual, allowing others to judge if the individual appears to have abnormal behaviours
Checklist - provides individuals with a practical checklist to check their behaviour
Personal perspective - allows the individual to have their own perspective of the mental disorder by recognising the personal experience of those suffering
Represents a threshold for help - provides a clear criteria for when individuals need professional help
Using 'Failure to function adequately' as a definition of abnormality
Has limitations
Limitations of using 'Failure to function adequately' as a definition of abnormality
Discrimination
Abnormality is normal
Abnormality and dysfunction do not always go together
Discrimination
Labelling individuals who make unusual life choices, e.g. those who complete unusual spiritual activities or base jumpers, as abnormal
Discriminating against cultures who make different life choices, e.g. Travellers, who may not live at a permanent address and choose not to work
Abnormality is normal
Behaving abnormally is normal at the loss of a loved one, through a divorce, taking exams
Abnormality and dysfunction do not always go together
People with dangerous personality disorders, such as psychopaths, can appear normal, e.g. Harold Shipman a respected doctor who murdered over 200 patients but was seen as a respectable doctor
Strengths of using 'Deviation of mental health' as a definition of abnormality
Holistic - looks at the whole person and their behaviour, instead of focusing on singular behaviours
Comprehensive - includes a range of reasons as to why individuals may need help with their mental health, and a range of criteria for distinguishing mental health from illness
Positive approach - focuses on positive behaviours and what is desirable instead of undesirable behaviours
Consistent - provides a consistent and standardised measurement for those looking at both positive and negative mental health
Limitations of using 'Deviation from ideal mental health' as a definition of abnormality
It is culturally specific for western cultures, while collectivist cultures would see autonomy as undesirable
It has over demanding criteria that are often hard to achieve constantly or all of the time
It does not account for changes over time, where behaviours that were once seen as normal are now abnormal and vice versa
It tries to treat mental health in the same way as physical health, however, mental health is much more subjective and needs to be looked at in the context of the patient
Diagnosing a patient with mental health is more complex than self questionnaires and often experienced professionals struggle to come up with an accurate diagnosis
Evaluation of statistical infrequency
Strengths
This method of defining abnormality uses an objective, standardised measure which means that it is reliable
Distribution curves are based on real data and, therefore, should be unbiased
Weaknesses
Depression is regarded as abnormal behaviour (a psychopathology) yet is so prevalent (1 in 6 adults in the UK have depression - 17% of the population) which means that it is not statistically deviant, hence using this as a measure of abnormality is unrepresentative
Having an IQ of 130 might be regarded as advantageous rather than as evidence of 'abnormality'
