One strength of the psychodynamic approach is that it considers a range of factors in understanding behaviour
For example, Freud argued that the superego is acquired from the same-sex parent, and so acknowledges role of the family
he also emphasised the role of instincts and feelings such as guilty, thereby considering the role of emotions
This matters because it means that the psychodynamic approach accounts for both internal and external factors
Therefore, it is arguably a more holistic explanation for behaviour than other approaches
