To Drill or Not to Drill: Do Memory Drills Help Strengthen Prospective Memory and Decrease Veterans' Concerns About Prospective Memory Problems?

Treatment-seeking veterans who come for diagnostics and/or treatment to University of California, Los Angeles (UCLA) Operation Mend show a high level of memory concern. To address this issue, the veterans receive training in evidence-informed compensatory strategies. However, a high level of memory concern remains, and this study aims to investigate the efficacy of adding memory drills to the treatment program.

There is mixed evidence in the literature about whether memory drills, which tend to show improvement in computerized cognitive tasks, generalize to naturalistic forms of memory. Specifically, the efficacy of computerized training for prospective memory (PM), perhaps the most naturalistic form of memory, is understudied. The proposed study seeks to answer the question whether adding a computerized "drilling" of retrospective and prospective memory to Operation Mend's Cognitive Training enhances patients' PM performance & reduces their memory concerns.

Study participants will be only be recruited from participants of the Operation Mend Intensive Treatment Programs (ITPs). The BRAIN ITP is a two-week intensive brain health program for patients who may have a history of mild traumatic brain injury and other comorbidities who wish to focus on improving their day-to-day cognitive functioning, maximizing their brain health as well as reducing the impact of other symptoms such as physical pain. It involves cognitive training sessions and meetings with neuropsychologists, neurologists, occupational therapists, dieticians, etc. The PTSD ITP is a two-week intensive therapy and skills training program for patients who wish to focus on evidence-based treatment for PTSD and other psychological and cognitive comorbidities that involves mental health sessions and meetings with psychiatrists, psychologists, neuropsychologists, etc.

This will be a randomized controlled trial with three groups. The experimental group with BRAIN ITP participants will receive the normal standard of care and memory drilling while the BRAIN ITP control group receives only the normal standard of care. The third control group will come from the PTSD ITP who receive normal standard of care plus PTSD treatment. This control group is included because of indications of a connection between PTSD symptomology and PM deficits.

In the BRAIN ITP, the standard PM training for both the experimental and control group takes place during the patient's individual sessions with a neuropsychologist. In total, there are seven sessions. At each of these sessions the neuropsychologist will review a new compensatory strategy for prospective memory and assign a naturalistic task for completion as homework to practice the strategy. The experimental group will receive the additional "memory drills" training. This training includes the completion of a list learning memory task and then a prospective memory task conducted on the computer at each session. The PTSD ITP group will receive the standard of care (cognitive processing therapy and cognitive training).
