Structured abstract:

Background:  Individuals who sustain traumatic brain injuries face a myriad of cognitive and other disabilities post injury. Deficits in executive functioning are one of the major problems that impact work. Psychosocial educational interventions and computer assisted training have helped some individuals learn to problem solve. Virtual reality may also be a useful tool.
Purpose:  This study explored whether or not participants with artificially intelligent VR based vocational problem solving skill training would show better problem solving skills and employment outcomes, than those who received conventional psychosocial program.
Setting:  The training modules were developed at a University lab in Hong Kong. Where the study took place was not clear.
Study sample:  The study sample included 40 people from Hong Kong with mild (N=20)and moderate (N=20) traumatic brain injury. Participants were randomly assigned to one of the two study groups.
Intervention:  The intervention was an artificial intelligent virtual reality-based vocational problem solving training program. Participants took part in 12 sessions that lasted 20 to 25 minutes each.
Control or comparison condition:  The control condition was traditional psycho-educational training.
Data collection and analysis:  The Wisconsin Card Sorting Test and the Tower of London Test were administered to participants. In addition, the Vocational Cognitive Rating Scale was completed by the participant's case manager or supervisor of a rehabilitation facility or center. After the pretest each participant started either the virtual or psychosocial training. The content and structure of the two programs were similar. Each included an introduction to training objectives, training in specific vocational skills and practice and a review of those skills. The virtual program was interactive in nature. The psycho educational vocational training system included a training manual and was delivered under the guidance of a trainer. Post test were also conducted on the previously cited measures. Information about the participants employment status was collected at one, three and six month intervals. Statistical analysis were performed suing SPSS for Windows Version 17.
Findings:  There was no significant differences in the participants in screening criteria or baseline of outcomes between the virtual training and psycho education program. Those who participated in the virtual training showed improvements in selective cognitive functioning. However, the training did not transfer to functional real world outcomes, as indicated by limited success in vocational outcomes. The virtual training was more cost effective than workshop based training.
Conclusions:  Virtual reality training may improve memory functioning and have other applications for vocational rehabilitation. More research is needed.
