A Psychologist Develops a New Treatment for Depression in the United

A psychologist develops a new treatment for depression in the United States that involves teaching people techniques to increase their self-esteem. Assuming that the treatment is successful in the United States, should the same treatment be used to treat depression in Japan?

A) Yes, because if a treatment is effective in one culture, it will be effective in all cultures.
B) Yes, because previous research has demonstrated that depression manifests itself in exactly the same way across these cultures.
C) No, because depressed people in Eastern cultures do not devalue themselves like depressed people in Western cultures.
D) No, because since all behavior is culturally dependent, it is highly unlikely that any therapy would be effective in more than one culture.
