Protocol outcome measures

Outcome measure	Outcome	Time of data collection and people completing	Description, scaling and content	Psychometric and other properties
Navigation Satisfaction Tool [34]	Acceptability in terms of satisfaction with care navigation and referral services used by service users	Navicare service users will complete up to 6-months after intake to Navicare or 3-months after last contact with Navicare	22-items rated on a likert scale from 1 (extremely dissatisfied, extremely unhelpful, or extremely small degree) to 7 (extremely satisfied, extremely helpful, or extremely large degree). Topics covered include the navigator’s ability to listen and understand service user concerns, the mental health system, information about potential treatment options, intake procedures, navigator’s helpfulness, likelihood of recommending the service, and overall satisfaction with the service, as well as levels of perceived effectiveness and satisfaction with aspects of the referred service [34]	Acceptable reliability, face validity, and predictive validity for service users of care navigation services [34]
Program Sustainability Assessment Tool [35]	Sustainability at the program level	Navigators and the research implementation team will complete at the end of one year of implementation at each site	40-items rated on a Likert scale from 1 (‘to little or no extent’) to 7 (‘to a very great extent’). Eight domains are environmental support, financial stability, partnerships, strategic planning, communications, program adaptation, program evaluation, and organisational capacity	Good fit of the data with the 8 domains using confirmatory factor analysis and acceptable internal consistency when used in chronic disease programs [35]
Study specific fidelity-adaptation tool	Fidelity and adaptation	Research implementation team will complete throughout the study. Member checking by the original co-developers of the Navicare model and implementation strategies	Items specific to the study will be developed based on FRAME, FRAME-IS, elements of adaptation [36], and the proportion and duration of activities in each phase similar to the Stages of Implementation Completion measure [37]. Data from multiple data sources will be mapped to the tool items (e.g., from semi-structured interviews, community consultations, workshops, observations at forums or site visits, implementation diaries and documents referred to in data collection activities). Member checking will be conducted against originally developed core intervention components and implementation strategies [36, 38]	Not applicable
