Supported accommodation provides individuals with complex mental health difficulties the opportunity to maintain a tenancy with different levels of staff support provided to develop and maintain living skills and engage in social and work activities. Physical features of the place people live, the support they receive from staff and the individuals needs all have the potential to impact on their ability to engage in activities that enable then to have increasing independence within the community.

The study will investigate the relationship between the physical and social features of supported accommodation environments and whether this facilitates or inhibits people with complex mental health difficulties' participation in everyday life, relationships, pursuing interests and work. The study will also consider whether people's needs have an effect on the relationship between the environment and their participation. The study will analyse data collected using measures of clients' levels of participation, features of the supported accommodation environment and how needs mediates this relationship.

The aim is to inform ways of working with people with complex mental health difficulties in supported accommodation that increase opportunities for participation in the activities they need, want and enjoy doing.

Mental illness is one of the main causes of disability and ill-health worldwide with severe mental illness linked to a reduced life expectancy of approximately 10-25 years. Individuals with complex mental health difficulties(CMHD) are those with severe mental illness whose conditions can result in social, cognitive and functional difficulties. These individuals possess the longest years lived with a disability and represent a large proportion of those disadvantaged or discriminated economically, socially and culturally. The impact of the social, cultural and physical environment on people with CMHD frequently resulting difficulties with participation which include isolation from friends, family and relevant services and higher levels of unemployment, subsequently, this restricts their participation in everyday roles and responsibilities. The lack of social interaction and constant low expectation of success projected onto individuals with CMHD also creates a loss of personal identity and reduces their ability to engage in activities they find meaningful. Therefore the relationship between the environment and an individual with CMHD's can be considered as dynamic, with the opportunity to participate in daily life, roles and responsibilities either being supported or restricted by the social, cultural and physical environment the person lives in.

Participation in activities that are meaningful to people with CMHD also enable them to meet their needs. Mental health needs include broad domains of health and social functioning which are essential to living and succeeding in the community. People with CMHD identify needs in relation to reframing their illness experience so they can do everyday things, having stable housing and a choice about where they live, having the ability to develop friendships, get married, earn money and have an increased sense of purpose or meaning to their day. Effectively identifying and addressing people with CMHD's needs has been linked to individual feelings of satisfaction and competence, motivation increased independence and having a greater quality of life. This introduces a link between participation and achievement of the health and social care needs of an individual where achievement of needs has been linked to increased participation in meaningful activities and improved social and emotional wellbeing.

A significant number of individuals with CMHD live in supported accommodation which aims to meet their needs and facilitate participation in daily living, social and work activities. Supported accommodation was originally developed as a result of deinstitutionalisation, which focused on moving individuals with CMHD out of hospital to live back in the community. Supported accommodation provides individuals with CMHD the opportunity to maintain a tenancy with different levels of staff support provided to develop and maintain living skills and engage in social and work activities. There is some evidence that the physical features of the place people live, and the objects or things that people require to participate in daily life and social features including the support they receive from support staff and family members have an impact on people with CMHD's opportunities to participate in activities that enable them to have increasing independence within the community. There is therefore evidence that the needs of individuals with CMHDs are associated with their level of participation in activities which in turn is influenced by environmental factors within supported accommodation. However, there is limited research available to confirm the relationship between the physical and social features of the environment and participation and the mediating effect of needs for people with CMHD living in supported accommodation.

The research will focus on identifying the relationships between environment and participation and if needs mediates this relationship within two types of supported accommodation;

1. Supported housing: tenancies in shared living with staff based on-site up to 24 hours a day. The focus is on rehabilitation, with people with CMHD supported to gain independent living skills.
2. Floating outreach services: provide support to people with CMHD living in their own self-contained tenancy. Staff are based off-site and visit individuals several times a week dependant on level of support required.

The research will use measures of the social and physical features of the supported accommodation environment, individuals' participation and need to identify the relationship between the environment and participation.

It is anticipated that the results will inform interventions for people with CMHD living in supported accommodation to maximise opportunities for participation.

Research Questions

• What is the relationship between the social and physical features of the environment and participation for people with complex mental health difficulties living in supported accommodation?
• Do needs mediate the relationship between environment and participation for people with complex mental health difficulties living in supported accommodation
• Establish the relationship between subdomains of the environment on participation for people with complex mental health difficulties living in supported accommodation.

Recruitment and Informed Consent

The detailed process is explained within the consent flowchart attached separately. The researcher will meet with staff and service managers to provide information regarding the study. They will then be asked to speak with clients about the research and provide them with the written information. A week later, the researcher will contact the service managers to confirm:

• How many clients are interested in participating in the study.
• If any clients have an attorney/welfare guardian/next of Kin that are able to consent for the research.
• A time that is convenient to meet potential participants and speak with attorney/welfare guardians.

Information on the study will be provided to the service manager for the supported accommodation, this will include participant information sheets. Clients will be approached by the service manager or support worker who will inform the researcher of clients who are willing to participate.

This will be followed by a decision making capacity process (explained in capacity flowchart attached) and gaining of consent from clients, staff and clients family members (if applicable). This will include the use of the UBACC for clients without welfare guardians/attorneys in order to determine research decision making capacity. Dependant the assessment clients will be appropriately recruited, consent forms signed and times to complete measures arranged (as seen in flowchart). The researcher will then proceed to arrange dates and times with all involved and conduct the measure tools detailed below. Interviews will be conducted within the supportive accommodation. These tools were picked in order to appropriately explore elements of the environment, needs and participation.

The study design aims to assess the environment, needs and participation through consideration of several perspectives including both staff and clients, this ensures an objective approach while also enabling the researcher to highlight any discrepancies in views as identified within the scientific justification.

Data collection and use of the measure tools will also follow theoretically proven and tested guidance that were developed for each tool. The data collection will be completed over a period of approximately one year. Throughout the process the study design takes into consideration possible complications with working with this client group with examples of this being appropriately adjusting interview styles (without moving from the base guidance of each tool) and times according to client needs.

Sample Size The study participants are the, approximately, 235 clients who are currently resident in the two types of, EHSCP managed, supported accommodation in Edinburgh; (117 clients receiving floating outreach services and 118 clients in 36 supported housing properties). Regarding the possible recruitment rate; Patel et al. conducted a large cross-sectional study assessing the proportion of individuals with psychosis willing to take part in research of 65%. Given that this is a similar population to our research study and anticipating that the 235 invited clients meet the inclusion criteria with this recruitment rate will yield approximately 153 participants.

The modelling process would initially undertake univariable regressions to identify those significant environment variables with participation prior to taking them on to the multivariable model stage. It is expected that both the univariable and multicollinearity checks will reduce the number of variables in the multivariable models. With the above recruitment figure and following Schmidt's recommendation for 15-20 subjects per variable for multivariable linear regression analysis, this would allow a model to include approximately 8-10 independent variables.

In addition bootstrapped regression estimates in the multivariable will be reported with their associated 95% confidence interval.

Proposed Analyses Descriptive statistics for the sample (e.g. age, gender, employment, diagnosis and hours of support) in the cross-sectional study will be reported with percentages and frequencies and, mean and standard deviation or median and inter-quartile range as appropriate.

To address the primary research question a regression analysis approach will be used to assess the relationships of Participation (overall score) with Environment (overall score) and Needs (figure 1 in attached documents). As the REIS is accommodation specific it will therefore be common to those participants within the same shared accommodation, and the analysis will take this in to account. Similarly for the secondary research question: an assessment of the mediating role of Needs in the relationship between Environment on Participation thereby determining the direct and indirect effects of Environment on Participation .

For the other secondary questions following the establishing of an association with environment on participation, a series of subsequent analyses will explore the impact of the environment's sub-domains on participation(overall score) and its sub-domains. Multi-collinearity will be assessed in all models.

The associated bootstrapped model regression coefficients will be reported with their 95% confidence interval.

The site is supported accommodation commissioned by the Edinburgh Health and Social Care Partnership (EHSCP) in Edinbrugh. The researcher will recruit participants living in two types, supported housing and floating outreach services. This is approximately 235 individuals. It is recognised that people who are resident in supported accommodation services are those with the most complex difficulties as a result of their severe mental illness. It is likely that some of the people resident in supported accommodation services will be subject to Community Compulsory Treatment Orders (CCTO) with a smaller number also having their needs managed by the Adults with Incapacity(Scotland) Act 2000.
