Abstract

OBJECTIVE: To examine associations among compensatory cognitive training (CCT), objective cognitive functioning, and self-reported cognitive symptoms. We examined whether change in objective cognitive functioning associated with participation in CCT at 10-week follow-up mediates change in self-reported cognitive symptoms associated with CCT at 15-week follow-up.

SETTING: Three VA outpatient mental health clinics.

PARTICIPANTS: Veterans with a history of mild traumatic brain injury who reported cognitive deficits.

DESIGN: Randomized controlled trial post hoc causal mediation analysis.

MAIN MEASURES: Self-reported cognitive symptoms were measured by the Prospective-Retrospective Memory Questionnaire and the Multiple Sclerosis Neuropsychological Screening Questionnaire. Objective cognitive functioning was measured using a battery of neuropsychological tests.

RESULTS: Improvement on the Hopkins Verbal Learning Test-Revised (HVLT-R) Delayed Recall test mediated the association between participation in CCT and decrease in the Prospective-Retrospective Memory Questionnaire total score. Improvement on the HVLT-R Total Recall and HVLT-R Delayed Recall tests both meditated the association between participation in CCT and decrease in the Multiple Sclerosis Neuropsychological Screening Questionnaire total score. No other measures of objective cognitive functioning were significant mediators.

CONCLUSION: Patients' perceptions of cognitive symptom improvement due to CCT are partially mediated by learning and memory, though these subjective improvements occur regardless of other changes in objective cognitive functioning associated with CCT.
