Overgeneral memory in depression and posttraumatic stress disorder: the role of intrusive memories
background Overgeneral memory has been the subject of much research since the time it was discovered more or less by accident. The literature provides several explanations for the underlying causes of overgeneral memory, linking it to traumatic experiences.
aim To review the literature on overgeneral memory in order to obtain more insight into the role that traumatic experiences play in the development of overgeneral memory on depression and posttraumatic stress disorder.
method Relevant literature concerning overgeneral memory and its relation to traumatic experiences was selected from the databases Psycinfo and PubMed using as key words 'overgeneral memory' and 'autobiographical memory' (specificity), in combination with 'trauma' or 'intrusive memory'.
results Overgeneral memory is a vulnerability factor for the development of depression and is associated with a poorer prognosis. Traumatic experiences in the past are in themselves insufficient to generate overgeneral memories. Intrusive memories seem to be the main factor contributing to the development of overgeneral memory.
conclusion So far, the role played by intrusive memories in the development of overgeneral memory has not been adequately investigated. More insight into the relation between intrusive memory and overgeneral memory may lead to adjustments in treatment.
