What is a strength for ‘Statistical Infrequency’ as a Definition of Abnormality?
Real World Application
Statistical infrequency is used in clinical practice, as both part of formal diagnosis and as a way to assess the severity of an individual’s symptoms
For example, a diagnosis of intellectual diability requires an IQ of below 70, while a score of 30+ on the BDI is widely interpreted as indicating severe depression
This shows that the value of the statistical infrequency criterion is useful in both diagnostic and assessment processes
What is a limitation for ‘Statistical Infrequency’ as a Definition of Abnormality?
Unusual Characteristics Can Be Positive
Infrequent characteristics, such as having a high IQ, can be positive, yet we would not think of someone for being abnormal for having such characteristics
Being unusual or at one end of a psychological spectrum does not necessarily make someone abnormal
This means that, although statistical infrequency can form part of assessment and diagnostic procedures, it is never sufficient as the sole basis for defining abnormality
What is a limitation for ‘Deviation from Social Norms’ as a Definition of Abnormality?
Cultural & Situational Relativism
A person from one cultural group may label someone from another group as abnormal using their standards rather than the person’s standards
For example, the experience of hearing voices is the norm in some cultures but would be seen as abnormal in the UK
This means that it is difficult to judge deviation from social norms across different situations and cultures
What is a strength for ‘Deviation from Social Norms’ as a Definition of Abnormality?
Real World Application
Deviation from social norms is used in clinical practice
For example, the key defining characteristics of antisocial personality disorder is the failure to conform to culturally acceptable behaviour, where these signs of the disorders are all deviations from social norms
This shows that the deviation from social norms criterion has value in psychiatry
What is a strength for ‘Failure to Function Adequately’ as a Definition of Abnormality?
Represents a Threshold For Help
Most of us have symptoms of mental disorder to some degree and according to Mind, around 25% of people in the UK will experience a mental health problem in any given year
However, many people press on in the face of fairly severe symptoms and it tends to be at the point that we cease to function adequately that people seek professional help
This criterion means that treatment and services can be targetted to those who need them most
What is a limitation for ‘Failure to Function Adequately’ as a Definition of Abnormality?
Discrimination and Social Control
In practice, it can be very hard to say when someone is really failing to function and when they have simply chosen to deviate from social norms
For example, not having a job or permanent address might seem like failing to function and for some people it would be, however people with alternative lifestyles may choose to live off-grid
This means that people who make unusual choices are at risk of being labelled abnormal and their freedom of choice may be restricted
What is a limitation for ‘Deviation from Ideal Mental Health’ as a Definition of Abnormality?
May Be Culture Bound
Some of Jahoda’s criteria for ideal mental health are located in the context of the US and so the different criteria are not equally applicable across a range of cultures
What defines success in our working, social and love lives is very different in different cultures and even within Europe, there is quite a bit of variation in the value placed on personal independence
This means that it is difficult to apply the concept of ideal mental health from one culture to another
What is a strength for ‘Deviation from Ideal Mental Health’ as a Definition of Abnormality?
A Comprehensive Definition
Jahoda’s concept of ‘ideal mental health’ includes criteria for distinguishing mental health from mental disorders and covers many reasons why we might seek help with mental health
This means that an individual’s mental health can be discussed with a range of professionals who might take different views
This means that ideal mental health provides a checklist against which we can assess ourselves and others and discuss psychological issues with a range of professionals
