An investigation of approach behaviour in Prolonged Grief.

Prolonged Grief (PG) is recognized as a potentially debilitating post-bereavement syndrome. Theoretical models of PG highlight the importance of both approach and avoidance behaviours in maintaining the syndrome. Research to date has focussed primarily on investigating avoidance in response to loss reminders. Comparatively few studies have indexed approach behaviours in PG. We use a quasi-experimental paradigm to simultaneously examine approach and avoidance behaviours to reminders of the deceased. Fifty-five bereaved individuals with and without PG responded to stimuli showing the deceased's name, an attachment figure's name, a neutral name, or a letter string, by pulling or pushing a joystick according to a whether the stimuli was a word or not. Concurrent visual feedback created the illusion that the images were either approaching or receding from the participant. Participants with PG were quicker to pull than push the three name stimuli, with quicker pulling of the deceased and attachment name than the neutral name. Non-PG participants responded more quickly to the attachment name but evidenced no relative approach or avoidance of any stimuli. Findings provide behavioural evidence about approach behaviour in PG, and are discussed with references to models that recognise the role of yearning for the deceased in PG.
