Multi-player Online Video Games for Cognitive Rehabilitation

Study Overview
=================
Brief Summary
-----------------
This research project aims to find out if a multiplayer online video game can provide therapeutic benefit for people who have survived a brain injury. Video games provide therapeutic benefits in many contexts (Griffiths, 2005). Players of online multiplayer games behave altruistically and form friendships (Wang and Wang, 2008). These positive emotional effects may enhance cognitive rehabilitation, because the cognitive and emotional sides of rehabilitation are connected (Mateer, 2005). The hypothesis is thus: that playing multiplayer online games can be a useful form of cognitive rehabilitation for brain-injured people. This research will identify whether or not multi-player online video games may be used as a complementary therapeutic tool. A further aim is to develop guidelines which would help others considering the use of video games for cognitive rehabilitation.

Detailed Description
-----------------
Purpose and design This research aims to find out if massively multi-player online games (MMOs), a relatively new type of video game, can be used as a form of therapy for people who have survived an acquired brain injury. Numerous previous studies have shown that video games can be used as therapy in many contexts. However, there is some evidence that video games are not an effective form of cognitive rehabilitation for brain injury survivors (Malec et al., 1984). The difference in this research is that MMOs incorporate social interaction into the game play experience. It is proposed that this strengthening of social bonds will be more beneficial than a similar single-player game. Due to the narrow focus of the research it is anticipated that the number of potential participants will be small, on the order of ten participants. It is recognised that such a small sample size is not compatible with a randomised controlled trial. Instead, the research will employ a single-subject research design, where a higher number of participants will strengthen the external validity of the results. The research question and design have been developed primarily by the Chief Investigator (PhD student), with critique from the supervisory team. Feedback has also been received from healthcare professionals who have been contacted by the C.I. Participants will be asked for their feedback on a video game and its user interface. This is to ensure that the video game is suitable for the participant, and that the participant is able to play it. This stage is expected to consist of three or four sessions of 30 mins duration, every 2 weeks. Participants will then be asked to play the video game for a number of sessions. The number of sessions is 21. The duration of each session is one hour. The sessions are to be held once per week. Null/alternative hypotheses The null hypotheses are that a single-player video game will not improve cognitive skills; and that a multi-player online video game will not improve cognitive skills. The alternative hypotheses are that a single-player game will improve cognitive skills, and a multi-player online game will provide further improvement. Study design The first stage of the research will be to design and refine a prototype online multi-player video game, working in collaboration with participants, firstly able-bodied, and then disabled. The researcher will work with each participant to develop a user interface which enables him or her to play the video game. The study will then employ a single-case research design for each disabled participant. An RCT would not be valid given the expected number of participants. Time-series data will be collected in three phases: to obtain a baseline; to measure the effects of a single-player video game; and to measure the effects of a multi-player online game. Each phase has seven sessions. The sessions are one hour, weekly. During the baseline phase, The participant will engage in a non-game task using the interface defined in the pre-trial phase. This phase may compensate for researcher effects. For the next phase, the participant will engage in a single-player version of the video game. For the final phase, the participant will engage in a multi-player online game. Player activity in the single- and multi-player games will be logged for analysis. Interviews with participants will be used to build a thick narrative of each participants' experience over the course of the study. Recruitment Participants will be recruited by contacting head injury units, day care centres, and organisations such as Headway and the ARNI Trust. The C.I. will meet with potential participants who express an interest in the study. A cornerstone of rehabilitation is that the goals are relevant to the client's everyday life. Therefore the details of how any individual's cognitive improvements will be measured must be based on a dialogue with each individual. Consent Informed consent must be given by a participant before any involvement in the study. A participant information sheet will be provided. The C.I. will be present to talk through the issues with the participant. The NHS guidelines for writing clear information sheets will be followed. Due to the nature of the participants' injuries, particular care and emphasis is placed on establishing capacity to give consent. The Department of Health gives guidelines on gauging capacity but family members and care workers will be a key source of guidance. It is expected that participants will provide a written signature on a consent form, but again due to the nature of the participant's injuries this may not be possible. In this case the verbal consent of the participant would be recorded and witness(es) would sign the form. Risks, burdens and benefits The main medical risk of playing video games is the possibility of epileptic seizure due to photosensitive epilepsy, (PSE). Minor risks are: the possibility of aches and pains; eye strain; and stress caused by extended periods of vigilance. These risks are mitigated by conducting the research at day care centres where medical staff will be on hand, and by limiting play to one hour per week, broken into smaller play sessions (e.g. 3 * 20 mins). Additionally, again to minimise risk of photosensitive seizure, screen luminance will be kept to a minimum. Other issues to consider when using video games as therapy are: video game addiction; violent content; and the offensive nature of some games. The issue of any potential addiction is mitigated by the short playing times; the issue of game suitability will be managed by previewing and discussing game content with participant, family members and carers as appropriate. Potential benefits to participants: Playing a suitable game should provide feelings of well-being and improved self esteem. With the added social aspect of multi-player online games, participants could also feel less isolated. These improvements in emotional health may have beneficial effects on cognitive skills such as communication. Confidentiality Participant personal details will be kept confidential. When data is reported, random numeric IDs will be used to refer to individuals. Guidelines issued by the Office of National Statistics will be followed when tabulated data contains cells with zeros or extremely low numbers, so that potential identification of participants is prevented.
