Abstract: In a long time bereavement researchers followed “Grief Work Hypothesis”, which lacking clarity in definition and emphasis “detachment from the deceased” were challenged by positive researches after 80s. New perspectives, including coping, attachment, emotional social function and trauma perspectives, were introduced into bereavement research. They broadened and deepened researchers’ eyesight. Recently, new integrated theoretical models were formed based on these perspectives. “Attachment and Dual-Process Model of bereavement”, a representative one of them, was introduced herewith. Also, the “Grief Work Hypothesis” was reconsidered in the new sphere of bereavement research

Key words: bereavement, grief work hypothesis, attachment, dual-process model of bereavement
