  • Definitions of abnormality
    • Statistical infrequency
      • An objective way of defining normal and abnormal behaviour once the cut off point is established
      • Looking at the number of times a behaviour is observed in society, classed as abnormal if it is statistically rare
      • Objective so is an easy and useful tool for clinical diagnosis
        • An objective way of defining normal and abnormal behaviour once the cut off point is established
      • Not all statistically rare behaviour is abnormal so it cant be used alone, doesn't take into account the desirability of the behaviour/trait
        • 100 is the average IQ, below 70 is the diagnosis of learning disability
    • Failure to Function Adequately
      • To be considered normal we must be able to cope with everyday life; maintaining hygiene+nutrition, relationships and jobs.
        • Depression; loss of appetite, interest, struggle to get out of bed, hard to complete everyday tasks.
      • It recongnises experiences of patients and views mental disorders from the point of view of the person experiencing it; considers whether the behaviour is causing an individual stress, leading to a more accurate diagnosis
      • Abnormality doesn't always mean a person cannot cope, tranvesticism is seen as a mental disorder but many individuals are able to cope with every day life, therefore this doesn't work with all cases.

    • Deviation from Social Norms
      • Rules in society which tell us how to behave, if a person does not follow these rules and acts differently they will be considered abnormal,
        • Tourettes: inappropriate remarks and continuous swearing is different to what society expects
      • Social norms change depending on the culture, hearing voices is seen as a sign of schizophrenia in the UK but in other cultures is desirable, doesn't account for abnormality in different cultures which could lead to a misdiagnosis
      • Distinguishes between desirable and undesirable behaviour, a behaviour can be statistically rare but desirable so isn't considered abnormal, such as high IQ.
    • Deviation from Ideal Mental Health
      • If an individual does not meet the 6 criteria, they are considered abnormal.
        • High self esteem, deal with everyday stresses, accurate view of reality, independence, able to change behaviour to suit environment,  personal growth
      • Positive way of looking at mental health, focuses on what is desirable and has a broad range; good tool when distinguishing as it increases accuracy.
      • The criteria are unrealistic, impossible to have high self esteem all the time, so someone may be considered abnormal when they're not.
