Description of intervention(s) / exposure
• Brief name: ‘Recovery ACT for Psychosis’ Group Program
• Materials: The ‘Recovery ACT for Psychosis’ Group Program includes seven core group sessions and one booster session. The topics that comprise the seven core group sessions are: introduction to noticing/awareness of present experiences and values; introduction to passengers on the bus metaphor and SMART goals; review of values, noticing and willingness; identification of passengers and different ways of responding to them and development of noticing skills; passengers on the bus and changing relationships with words; review of values and encourage sharing of value-guided actions; review of key group messages.
• Procedures: Psychoeducation, facilitated discussions and reflections, experiential activities (guided informal and formal meditations), reflective activities, planned out-of-session activities, role-play activities. Use of audio-visuals and handout materials to aid learning designed specifically for the intervention (http://actforpsychosis.com/). Reminder calls and/or messages to prompt attendance.
• Who will deliver?: The ‘Recovery ACT for Psychosis’ Group Program is conducted at participating centres either as part of a clinical program of groups routinely offered to consumers, or as periodic opportunities. Group leaders are primarily clinical psychologists employed by the centres as clinical service providers.
• Mode of delivery: Face-to-face in a group setting.
• Frequency of intervention: Eight 90-minute sessions; 7 core group sessions run once per week for 7 weeks, and a booster session about 4 weeks after session 7.
• Location: At community mental health service centres operated by four public health agencies in Melbourne, Australia.
• Personalised?: The intervention will not be personalised, titrated or adapted to groups of individuals in the intervention
• Adherence/fidelity?: Adherence to the intervention will be monitored by the senior investigators. Group clinicians will document whether there were any modifications to the group program. In addition, a semi-structured interview with the group clinicians after each group program will be conducted by senior investigators to gather qualitative data about the group program. The duration of the interview is estimated to be 30 minutes.
Allocation to intervention: The ‘Recovery ACT for Psychosis’ Group Program is an intervention already offered in routine practice in public mental health outpatient centres in Australia. All participants who were referred to (by clinician, treatment team, or self-referred) and decide to attend the ‘Recovery ACT for Psychosis’ Group Program will be invited to participate in the evaluation of the intervention.

Treatment: Other
Comparator / control treatment
This study is a single group quasi-experimental trial in that all participants serve as their own control. After consenting to participate in the evaluation and completing an assessment of the primary outcome, there is a minimum 3-4 week wait-list period that all participants undergo prior to the start of the active intervention. On the day of the first group session, all participants complete another assessment of the primary outcome before the session begins. Therefore, there is data for all participants on change in the primary outcome over the baseline period (no active intervention) that will be used to compare to data on change in the primary outcome during the active intervention.

Efficacy
Statistical methods / analysis
The estimated minimum sample size needed in this study to detect an effect is 90. As the statistical analysis plan for the study involves the use of a growth curve structural equation model of the primary outcome (personal recovery), we calculated the minimum sample sized based on the number of observed (5 observed variables from Time 0 to Time 4) and latent variables in the model (2 latent variables for intercept and slope), the anticipated effect size (0.3), and the desired probability (0.05) and statistical power level (80%).

To evaluate the primary outcome, we will use linear mixed-effects modelling to determine whether there is a significant difference in the primary outcome across each time period (T0 to T4).

To quantitatively investigate a model of the trajectory of change in the primary outcome, we will test a univariate latent growth curve model of the primary outcome from T0 (prior to waitlist period) to the start of the group (T1) to the booster session (T4).
