Although memory complaints are common in post-traumatic stress disorder (PTSD), the only published study of objective and subjective memory in PTSD by Roca and Freeman indicates that subjective complaints may not accurately reflect objective performance. The present study examined memory in 21 PTSD patients, 20 combat controls and 23 non-combat controls using two objective memory measures (Rey Auditory Verbal Learning Test; Backward Digit Span) and one subjective measure (Memory Functioning Questionnaire). Analysis of variances (ANOVAs) and analysis of co-variances generally did not reveal group differences for objective memory performance. For subjective memory complaints, ANOVAs indicated group differences; PTSD participants reported more memory problems than controls. These differences disappeared, however, when depression was included as a covariate. Also, we provide some preliminary evidence that depression may mediate the relationship between PTSD symptomatology and subjective memory complaints. Findings suggest that reductions in depressive symptomatology in PTSD may be associated with decreased subjective memory complaints.
