Quantitative outcome measures will be collected at 3 different timepoints: baseline, 6 months post randomisation and 12 months post randomisation. The primary outcome will be quality of life assessed via the Manchester Short Assessment of Quality of Life (MANSA) [Secondary clinical outcome measures include the psychiatric symptom severity score via Brief Psychiatric Rating Scale (BPRS) [Secondary social outcome measures include the objective social situation score via Social Situation Index (SIX) [Further secondary measures to evaluate the cost effectiveness of the intervention include health-related Quality of Life score via European Quality of Life version 5 (EQ5D-5L) [The baseline assessment will also include a socio-demographics questionnaire for all participants. Sociodemographics will be summarised as means and proportions.For all measures, the mean scores at 6 months and 12 months post randomisation will be calculated and compared between the intervention and control group, with the baseline values of each outcome included as covariate.A subset of 20 patients per country and all 7 clinicians who were randomised to the intervention arm will be invited to attend a qualitative interview after the end of the intervention (6 months) in order to capture the individual experience of the intervention, including barriers and facilitators of attending intervention sessions, suggested adaptations and the practical delivery of the intervention. These interviews will be conducted with the help of a semi-structured topic guide and will be audio recorded. Interviews will be conducted at the end of the intervention (6-month post randomisation) to ensure ease of recollection of the specifics of the intervention, without influencing data collection of the primary outcome.To maintain blinding of researchers within the study, monitoring of intervention fidelity and the qualitative follow-up interviews will be conducted by researchers who are aware of allocation. The other researchers will conduct the follow-up quantitative assessment and will remain blinded to intervention allocation. Participants and mental health professionals will be asked not to disclose details of the intervention during the follow-up quantitative assessments.
