abnormal if they fail to meet Jahoda’s criteria what is considered psychologically healthy - the more criteria they fail to meet, the more abnormal they are considered. Examples - having a high self-esteem, achieving self-actualisation, being able to resist stress, having an accurate perception of reality, and possessing the ability to master your environment - work, form relationships etc. E.g. An individual with depression would be considered abnormal - do not have high self-esteem/accurate perception of reality - irrational beliefs.
