Autobiographical memory impairments as a transdiagnostic feature of mental illness: A meta-analytic review of investigations into autobiographical memory specificity and overgenerality among people with psychiatric diagnoses.

= 712, 95% CI [0.524, 0.900], memories than diagnoses-free people. The size of these effects did not differ between diagnostic groups. There were no consistent moderators of effect size heterogeneity; effect sizes were not explained by methodological factors such as cue valence or demographic variables such as participants' age or between-group differences in process variables (e.g., rumination). Deficits in autobiographical memory retrieval may be a transdiagnostic factor, but further research in underrepresented diagnostic groups, and with novel experimental manipulations of encoding and retrieval processes, is warranted before full transdiagnosticity and the processes underlying reduced specificity/overgenerality can be established.
