Brief summary
Background: Adequate and stable housing conditions are fundamental for the psychiatric rehabilitation of individuals with severe mental illness (SMI). A common approach in psychiatric rehabilitation relies on a continuum of residential services that aims at enabling the person with SMI to live eventually independently. Current state of research, however, shows clearly that most persons in question remain in residential care settings or other treatment as usual conditions (RCS/TAU). The Independent Housing and Support (IHS) scheme is a new model that aims at direct placement in an independent accommodation in the community. Support is provided according to individual needs in a permanent housing situation without time limit. Up to now, randomized controlled trials (RCTs) to evaluate the effectiveness of IHS have only been conducted with homeless populations in North America. The purpose of the present study is to evaluate IHS compared to traditional RCS/TAU for non-homeless persons with severe mental illness. With this study, the investigators aim at demonstrating that IHS is not inferior to RCS/TAU. The rationale for utilizing a non-inferiority approach is based on the current state of research and on research that has shown strong preferences for IHS against RCS/TAU by people with SMI. Methods: As the preference issue makes RCTs in housing research difficult the investigators will use a specific time window in Zurich that allows conducting a RCT due to a scarcity of IHS settings and will combine the RCT with a comparative observational study in Berne where IHS is already well-established. At the Zurich site, a RCT compares the effects of living with IHS against living in residential care. At the Berne site, an observational study design (OSD) will be applied in connection with the same types of housing as in Zurich. Propensity scoring will be utilized to minimize the risk of bias in the OSD. A number of N=56 eligible subjects in Zurich and N=112 subjects (due to specific requirements for propensity scoring) in Berne complying with the inclusion criteria will be recruited and allocated to intervention and control groups according to the site-specific study designs. Recruitment period will last 21 months.
Interventions
BEHAVIORALIndependent Housing and Support (IHS)
Direct placement of people with SMI in an independent accommodation in the community, usually in a flat rented by the service user. Support is provided by a coach according to individual needs in a permanent housing situation without time limit.
BEHAVIORALResidential Care Settings and other Treatment as Usual (RCS/TAU)
Placement in a common residential home or supportive housing setting with the aim to gain psycho-social stability before being able to maintain independent housing.

Intervention model description
As the preference issue makes RCTs in housing research difficult the investigators will use a specific time window in Zurich that allows conducting an RCT due to a scarcity of IHS settings and will combine the RCT with a comparative observational study in Berne where IHS is already well-established. The investigators intend to directly compare the outcomes of a randomized controlled trial (RCT) with a study in an observational study design (OSD). Here, the investigators utilize the hypothesis that the OSD will provide similar results as the RCT.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Social Functioning Scale (SFS) | Change from baseline (T0) to 24 months (T3) | The SFS is a self-rating questionnaire and will be used to assess changes in participant's social inclusion in terms of the following subscales: 1) social engagement/withdrawal, 2) interpersonal behavior, 3) independence-performance, 4) independence-competence, 5) recreation, 6) pro-social activities, and 7) employment/occupation. The SFS includes 76 items in a varying answer format. In 68 items, participants are asked to answer on a 4-point Likert scale. The total-score ranges from 0 to 135 with higher score indicating better social inclusion. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Global Assessment of Functioning (GAF) | Change from baseline (T0) to 24 months (T3) | The GAF is a scale rated by key worker and will be used to assess changes in participant's functioning. Illness severity is rated as a single item based on psychopathology and functioning on a 1 to 100 scale with higher score as indicator for better functioning. |
| Manchester Short Assessment of Quality of Life (MANSA) | Change from baseline (T0) to 24 months (T3) | The MANSA is an interview and will be used to assess changes in participant's quality of life.

Four of the section three questions are termed objective and are to be answered with yes/no. Twelve of the section three questions are called subjective and ask for answering participant's satisfaction on a 7-point Likert scale. The final score will be computed by averaging the 12 individual items with higher score indicates higher quality of life. |
| Symptom Check List (SCL-K-9) | Change from baseline (T0) to 24 months (T3) | The SCL-K-9 is a questionnaire and will be used to assess changes in participant's mental state on a 5-point Likert scale, including items from all of the nine subscales of the original SCL-90-R: 1) depression, 2) anxiety, 3) somatization, 4) phobic fear, 5) obsessive-compulsive, 6) psychoticism, 7) social insecurity, 8) paranoid thinking, 9) hostility.
