Failure to Function Adequately

Failure to function adequately refers to an abnormality that prevents the person from carrying out the range of behaviours that society would expect, such as getting out of bed each day, holding down a job.
Rosenhan & Seligman suggested seven criteria that are typical of failure to function adequately these include personal distress (anxiety or depression), unpredictability (displaying unexpected behaviours and loss of control), and irrationality, among others. The more features of personal dysfunction a person has, the more they are considered abnormal.
To assess how well individuals cope with everyday life, clinicians use the Global Assessment of Functioning Scale which rates their level of social, occupational, and psychological functioning.

The definition provides a practical checklist of seven criteria individuals can use to check their level of abnormality.
It matches the sufferers’ perceptions. As most people seeking clinical help believe that they are suffering from psychological problems that interfere with the ability to function properly, it supports the definition.

might not be linked to abnormality but to other factors. Failure to keep a job may be due to the economic situation, not to psychopathology
Cultural relativism is one limitation; what may be seen as functioning adequately in one culture may not be adequate in another. This is likely to result in different diagnoses in different cultures.
FFA is context dependent; not eating can be seen as failing to function adequately, but prisoners on hunger strikes making a protest can be seen in a different light. fasting
