- realworld application - had a huge influence on psychology and Western contemporary thought. Alongside behaviourism, the psychodynamic approach remained the dominant force in psychology for the 1st half of the 20th century and has been used to explain a wide range of phenomena such as personality development, abnormal behaviour, moral development and gender. The approach has also been significant in drawing attention to the connection between experiences in childhood, such as our relationship with our parents, and later development. THEREFORE The applications of the approach support its external validity as they suggest that the principles can be used to explain a wide range of behaviours.
- Freud brought to the world a new form of therapy, called psychoanalysis. This employs a range of techniques designed to access the unconscious e.g. dream analysis and hypnosis. Freud and his followers were the first to demonstrate the potential of psychological, rather than biological, treatments for disorders such as depression and anxiety. A large-scale review of psychotherapy studies concluded that psychoanalysis produced significant improvements in symptoms that were maintained years after treatment THEREOFREThe applications of the approach support its external validity as they suggest that the principles can be used to help to support treatments. However, these treatments require a lot of effort from the patient because they have to think about their problems unlike with drug therapies. Additionally, psychoanalysis has been criticised as inappropriate, and even harmful, for people suffering from more serious mental disorders such as schizophrenia
- Many of the claims of psychoanalysis have been tested and many of them have been supported by scientific methodology. For example, a meta-analysis concluded that experimental studies of psychoanalysis compare well with studies relevant to any other major area of psychology. In particular, they found support for the existence of unconscious motivation in human behaviour as well as for the defence mechanisms THEREFORE These support the validity of the psychodynamic approach as they support the importance of the unconscious and defence mechanisms in behaviour.
- Defence mechanisms have face validity - they seem to logically make sense to people as part of their everyday experience e.g. Why people can't remember the impact of a car crash as they've repressed it --> might be a valid explanation of behaviour
