The Tailored Evidence-based Enhancements in Mental Health-Gamified and Individualized Follow-Up Treatment for Suicide (TEEM-GIFTS) : Implementing a Gamified mHealth Intervention to Reduce Post-Discharge Suicide Risk in Patients With Mental Disorders Using Multiphase Optimization Strategy (MOST)
Patients with mental disorders are at significantly higher risk of suicide after discharge compared to the general population and patients with other diseases. Currently, there is a lack of post-discharge community suicide risk management services in China. The research team's preliminary research suggests that mHealth interventions are well-accepted and feasible for reducing the suicide risk in patients with mental disorders. Furthermore, the inclusion of gamification elements can enhance treatment adherence and user engagement. However, determining the appropriate combination of gamification elements and evaluating the implementation effectiveness of gamified mHealth interventions for suicide risk are challenges in transforming these into regular community mental health services. This study will leverage gamification theory and community-based participatory research to design a gamified mHealth intervention model aimed at reducing suicide risk among discharged patients with mental disorders, and to develop a corresponding management strategy. Using the multi-phase optimization strategy (MOST), the study will identify the optimal combination of gamification elements to reduce suicide risk and increase the outpatient follow-up rate. Through an implementation science framework, the investigators will evaluate the process, outcomes, cost, and feasibility of this management strategy with the goal of reducing suicide risk among these patients. The findings from this study will provide a scientific basis for innovative suicide risk management models for discharged patients with mental disorders in China, thereby paving the way for the application of implementation science in mental health.
The Tailored Evidence-based Enhancements in Mental health (TEEM) projects, adhering to implementation science principles, encompass various studies aimed at improving mental health care in China. Among these is the Gamified and Individualized Follow-Up Treatment for Suicide (GIFTS) study. Based on the multi-phase optimization strategy (MOST), this is a mixed-methods study with three phases. The selection phase involves forming the gamified mHealth suicide risk management strategy and system through community participatory research. The optimization phase involves testing and adjusting the intervention elements for the gamified mHealth strategy through a factorial design randomized controlled trial (RCT) to evaluate the effectiveness of different combinations of intervention elements in reducing suicide risk. The confirmation phase will assess the optimized strategy based on the Implementation Outcomes Framework (IOF), focusing primarily on patient outcomes obtained through a standard RCT.
Selection phase Based on literature review, the research team has identified several gamification elements, including avatar, points, badges, missions, level & leaderboards, team mates & team missions, venting space, mood sharing, achievement and titles, and rewards, etc. During developing the gamification mHealth app (TEEM), the investigators categorize the elements into four types of intervention elements as Routine Tracker, Mind Care, Social Connectivity, and Achievement & Rewards; meanwhile, under the community-based participatory research (CBPR) framework, the investigators aim to explore the appropriate content of gamification mHealth interventions, the acceptance and feasibility of such interventions among discharged psychiatric patients, as well as structural and perceptual barriers during implementation.
In specific, the research team will recruit discharged patients with mental disorders and their lay health care supporters (LHSs) who are usually their family members, psychiatrists and nurses, psycho-crisis intervention team members, community mental health workers and mental health social workers as the community team, and will categorize the community team into three sub-groups, the patients-LHSs group, the clinic mental health service provider group (psychiatrists and nurses, and psycho-crisis intervention team members), and the community mental health service provider group (community mental health workers and mental health social workers). The investigators will conduct three focus group interviews in each sub-group and ten to fifteen cases of individual in-depth interview with the community to avoid bias in focus groups and to protect privacy related to personal experience in suicide and suicide intervention. There will be scheduled meetings with the community to discuss and revise the intervention strategy before implementation. Purposive sampling will be applied to recruit participants for the community team. For each type of sub-group, there will be five to eight members
Optimization phase The research team will conduct a a factorial design randomized controlled trial (RCT) to evaluate the effectiveness of different combinations of intervention elements in reducing suicide risk. There are four intervention elements as mentioned, thus there will be 16 groups in the factorial design RCT. The research team will recruit discharged patients with mental disorders from Shenzhen Mental Health Center/Shenzhen Kangning Hospital (SKH).
The research team sets the standard for optimizing interven elements as follows: The experimental group implementing the intervention element and the experimental group not implementing the intervention element should have an effect difference in reducing the suicide risk by 35%, which will be used as the basis for calculating the sample size of this study. This study aims to detect a 35% difference (δ) in the implementation of the intervention elements with a test level of α=0.05 and a test power (1-β) of 80%. A total of 260 patients need to be recruited for this study. Assuming a loss to follow-up rate of 20% and considering the number of experimental groups, the final sample size is 320 patients.
In accordance with the factorial design, the optimization phase will consist of 16 groups, and this is due to the four types of intervention elements and their 16 possible intervention conditions. Thus, after recruitment and the baseline survey, participants will be assigned into Group 1 to Group 16 by simple randomization in R program, with 20 participants in each group. Further, participants in each group will only have access to a single intervention condition of elements assigned to their group. Noted, the intervention app TEEM will be developed during the selection phase, and there will be an Android/iOS version of TEEM and a mini-program in the WeChat platform. Participants, LHSs, nurses who perform recruitment and baseline survey, and investigators who perform follow-ups will be blinded to the assignment.
To evaluate post-discharge suicide risk more cautiously and to provide crisis intervention in time, face-to-face interview will be conducted to collect information. Trained nurses in SKH will recruit participants and perform baseline survey. The research assistants will contact participants, schedule visits to SKH out-patient clinics , and complete follow-up questionnaires after out-patient visits at one week, one month, and three months after discharge. If participants refused subsequent visits, the investigators would schedule home visits to complete the survey by research assistants and community mental health workers. The condition that resulted in the greatest decrease in participants' suicide risk three months after discharge is the optimized intervention condition.
Confirmation phase This phase will assess the optimized intervention, focusing primarily on patient outcomes obtained through a standard RCT, in which intervention group (Group 17) will receive the optimized intervention condition and the control group (Group 18) will receive care as usual. Similar to the optimization phase, the research team will recruit discharged patients with mental disorders from SKH. The sample size (n=320) and randomization process will be consistent with optimization phase. Data collection, baseline survey and follow-up schedule are similar to the optimization phase. The primary outcomes are suicide risk and the rate of re-visits to outpatient clinic at three months after discharge. Secondary outcomes will be illustrated later in the Outcome measures section.
Study outcomes and measurements The implementation outcomes of the overall project are based on the Implementation Outcomes Framework, in which detailed primary and secondary outcomes of the study will be collected at 3 months after discharge.
