A strength of the psychodynamic approach is that it has practical application in the realworld.
For example, Freud brought to the world a new form of therapy, psychoanalysis which is designed to access the unconsciousmind by employing a range of techniques such as hypnosis and dreamanalysis.
Although it is not suitable for individuals with seriousmental disorders (e.g. schizophrenia), psychoanalysis has been successful with those suffering from mild neuroses.
This strengthens both the applicability and support for the psychodynamic approach in explaining human behaviour, given that it is the forerunner to many modern-daypsychotherapies that have since been established.
A limitation of the psychodynamic approach is that it is based on psychic determinism.
For example, the approach explains that all behaviour is determined by unconsciousconflicts.Freud believed that there was no such thing as an 'accident' and that even something as random as a 'slip of the tongue' is said to have a deepersymbolic meaning and is driven by unconscious forces.
Suggests that any freewill we think we may have is just an illusion.
This weakens the support for the psychodynamic approach in explaining human behaviour as it takes an extremelydeterminist stance by suggesting that free will may have noinfluence of behaviour.
Another limitation of the psychodynamic approach is that the casestudy method Freud relied on has been criticised.
For example, Freud's theory was based on the intensive study of individuals who were often in therapy (e.g. Dora and LittleHans). Critics suggest it's notpossible to make such universalclaims about human nature based on a limitedsample of people who were psychologically abnormal.
Furthermore, his interpretations were highly subjective and it is unlikely that any other researcher would have drawn the same conclusions.
This weakens both the populationvalidity and support for the psychodynamic approach in explaining human behaviour as Freud's research was idiographic and lacked scientific rigour compared to other approaches.
