While Karen Horney focuses more on interpersonal relationships during childhood, Alfred gives greater importance to personal goals of an individual.
There are, in my opinion, Horney would attribute the cause of depression to parental relations with children which are characterized by excessive interference or indifference. Deep anxiety would result from the behaviour rewards the child which, if is erratic, indifferent and discouraging feelings of isolation and helplessness will also emerge. Alfred Adler would, on the other hand, attribute depression to the feeling of inadequacy and guilt arising within the individual, due to the inability to achieve his/her personal goals. These goals provide an individual with security and are important in overcoming feelings of inadequacy. If individual is not able to attain the goals and could not overcome inferiority appropriately then it leads to depression.
