Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A Zoom assessment then 4x 2 hour weekly sessions of Zoom group transdiagnostic cognitive behavioural therapy (Group TCBT) for anxiety and depression. Maximum of 10 participants/group.

Group TCBT will be facilitated by an experienced psychologist familiar with Group TCBT in various forms and co-facilitated by a community therapist (nurse/Occupational Therapist/Social Worker/ or Psychologist) familiar with individual brief intervention counselling (the usual intervention for patients with anxiety and depression in the community).

The Group TCBT will follow a manual developed specifically for this group by the experienced psychologists. The community therapist will participate in a 1 day training programme prior to group commencement.

Content of the group will cover the following content: Socialisation to the group, goal setting and motivation, introduction to the TCBT model, understanding the function of emotion, emotion-driven behaviours and the role of avoidance, behavioural activation, learning to observe emotions and thoughts (mindfulness exercises). Thinking biases and thought restructuring, behavioural experiments, awareness of and tolerating physiological sensations (including interoceptive exposures), and relapse prevention. A treatment integrity checklist will be used to ensure all planned content is covered during each group programme.

Attendance at groups will be monitored. Assessments for the groups will occur in the month prior to group commencement.

Outcomes
Primary outcome [1] 320506 0
Feasibility of study intervention measured by:

If greater than 50% of patients fail to complete at least 3/4 group treatment sessions, we will deem the trial unfeasible. Group attendance will tracked by taking a role and recorded for each group.
Timepoint [1] 320506 0
1 month (therapy completion)
Primary outcome [2] 320507 0
Acceptability of treatment and study protocol measured by:

If fewer than 75% participants complete psychological measures at the 4 time points (baseline, 3,6, and 12 months) in both groups, the study will be deemed unfeasible.

Outcome measures are the PHQ-9 and GAD-7. These will be completed face to face at the assessment and then through telephone contact with the research assistant for subsequent time points.
Timepoint [2] 320507 0
Acceptability of treatment and study protocol measured by: If fewer than 75% participants complete psychological measures at the 3 time points (baseline, 3,6 months), the study protocol will be deemed unacceptable to participants. Outcome measures are the PHQ-9 and GAD-7. These will be completed face to face at the assessment and then through telephone contact with the research assistant for subsequent time points.
Secondary outcome [1] 371599 0
Reliable recovery. The definition of reliable recovery is taken from the Improved Access to Psychological Therapy (IAPT) study in the UK.

Reliable recovery is measured by scoring above clinical cut-off for PHQ-9 and GAD-7 at baseline assessment, scoring below clinical cut-off for PHQ-( and GAD-& at the end of treatment, and showed reliable improvement over treatment (pre-post change in PHQ-9>5,3 and GAD-7>3,53) (these are minimal change criteria and not results per se).
Timepoint [1] 371599 0
3 and 6 months post baseline assessment
Secondary outcome [2] 371600 0
This is a composite measure measuring the acceptability and effectiveness of training group trans-diagnostic facilitators. This will be assessed by a brief qualitative survey still to be designed specifically for the study.
Timepoint [2] 371600 0
Immediately following the 1 day training session.
Secondary outcome [3] 371841 0
Acceptability of study intervention and design for Maori participants measured by sub-group analysis of recruitment, treatment completion, drop-out rates, and satisfaction ratings.
Timepoint [3] 371841 0
Baseline and 3,6 months

Efficacy
Statistical methods / analysis
This is a feasibility study. No power calculation is required.
Study feasibility will be measured using descriptive statistics (percentage approached who participate, percentage completing treatment, percentage completing follow up measures, and percentage achieving reliable recovery).

Reliable recovery rates and completion rates will be compared between groups using comparative statistics (repeated measures ANOVA).
