Feasibility of a pocket-PC based cognitive control intervention in dementia spousal caregivers

Spousal caregivers of patients with dementia are in need of interventions to bolster their quality of life. Computer-based, self-administered cognitive training is an innovative approach to target spousal caregiver distress and coping. We tested the feasibility of administering one such intervention with minimal clinician intervention.

Twenty-seven elderly adults (>64 years old), who each were the primary caregiver for a spouse with dementia, were recruited through the Memory Disorders Clinic of the Alzheimer Disease Research Center in Pittsburgh, PA. Spousal caregivers were instructed to use a handheld computer version of the Adaptive Paced Visual Serial Attention Task (APVSAT) at least three times per week for four weeks as part of a larger caregiver intervention trial (P01 AG020677). Feasibility was explored by examining the frequency of APVSAT usage.

Results suggest that self-directed cognitive training is feasible for spousal caregivers of dementia patients. The mean usage of the APVSAT was 42 (SD = 28.58). Performance increased from the beginning to the end of the trial, and usage was not affected by stress, worry, or poor sleep quality.

Findings suggest the potential utility of cognitive training via handheld computer for spousal caregivers of dementia patients to improve problem solving, coping and adaptation, planning, and persevering with goal-directed tasks.
