A Meta-Analysis of the Influence of Cue Valence on Overgeneral Memory and Autobiographical Memory Specificity Among Youth.

Abstract

Overgeneral memory (OGM), or difficulty recalling specific memories when recounting autobiographical events, is associated with psychopathology. According to functional avoidance theory, OGM-or reduced autobiographical memory specificity (AMS)-may serve as an emotion regulation strategy that aids in the avoidance of painful, negative memories (Sumner,2012; Williams et al., 2007). Some researchers argue that there may be a valence effect for OGM, such that there is a higher frequency of overgenerality when recalling negative memories compared to positive memories. Although not supported among adults, valence effects may be present among children and adolescents if OGM initially develops in response to negative cues and then generalizes to all memory recall over time. This meta-analysis examined differences in child and adolescent OGM and AMS based on cue valance; standardized mean differences between negative and positive valence cues for OGM and AMS indices were calculated. Following PRISMA guidelines, a systematic literature search resulted in 26 studies assessing OGM and 30 assessing AMS. There was a significant effect of valence on OGM (d = 0.17, p = 0.01) and AMS (d = -0.20, p = 0.01). There was a higher frequency of overgeneral responses to negative cue words than positive cue words. Similarly, there was a higher frequency of specific responses for positive cue words than negative cue words. Subgroup analyses considering differences in valence effects by participant age (childhood vs. adolescence), sample type (clinical vs. community), and task instructions (verbal vs. written) were not significant. Theoretical advancements for our understanding of OGM and AMS and clinical implications are discussed.
