Overview
Brief Summary
The present study aimed to investigate the effects of a Virtual Reality cognitive training intervention (VRCTI) on cognitive function changes measured with a cognitive test battery and improvement of quality of life in older adults with cognitive impairment in long-term care facilities. Weekly 1-hour sessions were implemented over 8 weeks targeting sustained and selective attention, memory, cognitive functions, and rule deduction. The passive control group received usual care.
Detailed Description
Objectives: The present study aimed to investigate the effects of a Virtual Reality cognitive training intervention (VRCTI) on cognitive function changes measured with a cognitive test battery and improvement of quality of life in older adults with cognitive impairment in long-term care facilities. Method: Weekly 1-hour sessions were implemented over 8 weeks targeting sustained and selective attention, memory, cognitive functions, and rule deduction. The VRCTI comprised 12 different tasks distributed in 8 sessions with different difficulty levels. The passive control group received usual care. Older adults were randomly assigned to either VR or control groups. An experimental pre-post design was used. Accuracy, error, and repetition rates were measured throughout each session. Intervention effects were analyzed using a generalized estimating equation model.

Outcomes
Primary Outcomes
World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF)
Time Frame: Change is being assessed. Change in World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF) from baseline to immediately after the intervention.
The WHOQOL-BREF contains 28 items classified into the same 4 domains related to quality of life (physical health, psychological, social relationships and environment). All items were rated on a 5-point scale with a higher score indicating a higher quality of life.
Clock Drawing Test-Drawing Part, (CDT-D)
Time Frame: Change is being assessed. Change in Clock Drawing Test-Drawing Part, (CDT-D) from baseline to immediately after the intervention.
The CDT-D has been widely used as a neuropsychological screening test in the detection of cognitive impairment in populations. The lower the patients' clock scores the more likely were patients to be classified as impaired in elderly outpatients.
Cognitive Assessment Screening Instrument (CASI)
Time Frame: Change is being assessed. Change in Cognitive Assessment Screening Instrument (CASI) from baseline to immediately after the intervention.
The CASI evaluates global cognitive function using 9 cognitive domains: long-term memory, short-term memory, attention, mental manipulation, orientation, abstraction and judgment, language abilities, visual construction, and list-generating fluency. Typical administration time is about 20 minutes. The total score ranges from 0 to 100. A greater score demonstrates better global cognitive function.
Mini-Mental State Examination (MMSE)
Time Frame: Change is being assessed. Change in Mini-Mental State Examination (MMSE) from baseline to immediately after the intervention.
General cognitive functioning was assessed with the Chinese version of the MMSE, which is a cognitive screening tool used to evaluate cognitive decline, screen for cognitive impairment, to evaluate the severity of the impairment, and to monitor cognitive change over time. The higher score indicates the better cognitive function.
