Outcome measure

Instrument

Description

Reference (instrument)

Effectiveness outcomes

 30-day and annual readmission rates and annual emergency services utilization

Administrative data

 Psychological wellbeing

The Clinical Outcomes in Routine Evaluation - 10 (CORE-10)

A 10- item instrument developed to monitor clinically significant change in outpatients.

The CORE-10 covers four domains: Well-being, problems/symptoms, functioning, and risk, and sums up in two total scores: the mean of all items, and the mean of all non-risk items. These measures will be assessed at baseline, six and 12 months for each participant.

Skre et al. 2013 [52]

 Quality of life

The 5-level EQ-5D version (EQ-5D-5L)

The EQ-5D-5L comprises of 2 sections: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).

The descriptive system consists of five components: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each component has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems.

The EQ VAS can be used as a quantitative measure of health outcome ranging from worst imaginable health to best imaginable health, reflecting the patient’s own judgement.

These measures will be assessed at baseline, six and 12 months for each participant.

Herdman et al. 2011 [53]

 Patient’s recovery

Recovery Assessment Scale (RAS)

The Recovery Assessment Scale (RAS) is a 20-item measure developed based on a process model of recovery. The RAS evaluates various aspects of recovery with a special focus on hope and self-determination. These measures will be assessed at baseline, six and 12 months for each participant

Giffort et al. 2000 [54]

 Patient’s resilience

The Brief Resilience Scale

The Brief Resilience Scale evaluates the perceived ability to bounce back or recover from stress. These measures will be assessed at baseline, six and 12 months for each participant.

Smith et al. 2008 [55]

 Client satisfaction/Experience surveys.

Instrument developed and pilot tested, and published by the authors

Evaluates clients’ satisfaction and experiences with supportive text messaging programs. These measures will be assessed at 12 months for each participant.
