Does the virtual shopping training improve executive function and instrumental activities of daily living of patients with mild cognitive impairment?

To date, ecological validity of virtual shopping training for patients with mild cognitive impairment (MCI) has not been confirmed yet. Main objective of this study was to investigate effects of virtual shopping training on executive function and instrumental activities of daily living (IADL) in patients with MCI. 32 patients with MCI were randomly assigned to the experimental group that received virtual shopping training or the waitlist control group for a total of 16 sessions. To examine effects of virtual shopping training on executive function and IADL, Korean version of the Executive Function Performance Test (EFPT-K) and Korean Instrumental Activities of Daily living (K-IADL) were conducted. After the 16 sessions, the experimental group showed greater improvement in the EFPT-K (p < 0.001) and the K-IADL (p < 0.001) compared to the control group. These results suggest that virtual shopping training might be clinically beneficial to enhance executive function and IADL in patients with MCI.
