Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
As a pragmatic trial, all participants have the option to self-select into an eight week, yoga therapy program in addition to treatment as usual (control condition) consisting of 8 weekly group yoga sessions of 60 minutes each and a personalised home practice. The yoga practice includes:
- Gentle asana (physical postures) suitable for all levels of experience and utilising suitable modifications where necessary. Postures may be standing, lying or sitting.
- Breath awareness and implementation of pranayama techniques. The main technique taught and utilised during the 8 weeks will be ujjayi breathing (observation of breath drawing softly through back of nose and throat space during inhalation and exhalation) with a focus on extending breath length.
- Relaxation with a movement towards meditative focus. The goal at the end of each class will be to give participants a deep experience of relaxation and a direction towards focusing the mind.

The personalised practice will be developed by the Yoga Teacher based on the participants needs and abilities. It will consist of 15-30 minutes of breath-based movement and relaxation, encouraged to practice at home practice each day (at least three days per week).

Participant attendance to group classes will be recorded by the yoga teacher and they will complete weekly practice logs regarding the frequency and their experiences of the home practice.

Comparator / control treatment
All participants will attend a two-hour group therapy session session once a week for eight weeks as per their usual treatment. The program draws on the manualised CBT Mood-Management Course protocol, adapted from the Centre of Clinical Interventions (Nathan et al., 2004). It is designed to provide effective treatment for individuals experiencing anxiety and depression in a group setting that is comparable in efficacy to individual CBT (Craigie & Nathan, 2009). The program aims to assist individuals to:
- Gain an understanding of depression and anxiety,
- Learn practical strategies for managing them,
- Practice the techniques both in and outside of the group setting, and
- Learn how to maintain the gains they have made during therapy and prevent relapse.

The program is conducted at the clinic by a Clinical Psychologist and up to three Provisional Psychologists. It typically consists of 10 participants per group, and includes the following concepts:
- Education about depression and anxiety,
- Identifying activities that give a sense of pleasure or achievement, and working to include these in regular routines,
- Learning to break down overwhelming tasks into manageable steps,
- Learning a breathing technique to manage physical symptoms of anxiety,
- Cognitive therapy (identifying, questioning and changing unhelpful thoughts), and
- Learning how to actively cope with problems.

Outcomes
Primary outcome [1] 306529 0
Clinically significant change will be assessed based on the totals scores of the Depression Anxiety Stress Scale - 21 items (DASS-21)* (Lovibond & Lovibond, 1995). The DASS-21 is a self-report measure that consists of three scales designed to assess the emotional states of depression, anxiety and stress. Each of the three scales contains seven items that are scored from 0 (did not apply to me at all) to 3 (applied to me very much or most of the time). Scores are calculated for each subscale, with the total score calculated by summing each subscale multiplied by two. The scale is reported to have high internal consistency (Cronbach’s alpha = .92) and re-test reliability (r = .91) (Lovibond & Lovibond, 1995).

The Cognitive and Affective Mindfulness Scale-Revised (CAMS-R)* will also be in the battery of measures (Feldman et al., 2007). The CAMS-R is a self-report measure that involves 10 statements phrased in everyday language that reflect the four first order factors of mindfulness: attention, present-focus, awareness, and acceptance. Respondents rate their agreement with the statements from 1 (rarely/not at all) to 4 (almost always), where higher scores reflect greater mindful qualities overall. The CAMS-R has demonstrated acceptable internal consistency and evidence of convergent and discriminant validity with concurrent measures of mindfulness, distress, well-being, emotion-regulation and problem solving (Feldman et al., 2007).

The Outcome Rating Scale (ORS) is a brief visual analogue self-report measure of individual functioning (Miller, Brown, Sparks & Claud, 2003). The ORS assesses how individuals are feeling across four areas of functioning: individually, interpersonally, socially and overall. Scores for each domain range from 0-10, and are totalled to an overall score out of 40. Scores below 25 indicate symptoms of clinical significance. The scale demonstrates good psychometric properties and is sensitive to change in treatment-seeking populations (Miller et al., 2003).

The Mental Health Recovery Star is a self-report outcome measure which invites individuals to measure their own recovery progress across ten aspects of life, including: living skills, relationships, work and identity, and self-esteem (MacKeith & Burns, 2008). Each domain is rated alongside the “Ladder of Change”, from 1-10, where scores of 10 indicates full recovery. The Mental Health Recovery Star has been found a valid and useful tool in the Australian mental health service sector (Lloyd, Williams, Machingura & Tse, 2015).

The Beck Depression Inventory II (BDI-II)* is one of the widely accepted instruments for measuring depression in adults. It is a 21-item scale arising from clinical observations. Recent additions include items relating to agitation, worthlessness, concentration difficulty and loss of energy. Scores range from 0-63, with a suggested cut-off score of 17 or higher indicating the presence of clinical depression (Beck, Steer & Brown, 2000).

Assessment of Quality of Life (AQoL 8D)* is a patient self-report instrument that aims to assess of quality of life and provides opportunity to assess health economic metrics (Maxwell, Özmen, Iezzi & Richardson, 2016). The AQoL-8D consists of 35 items, which examine quality of life across the following domains: Independent Living, Happiness, Mental Health, Coping, Relationships, Self Worth, Pain, and Senses. It takes approximately 5 minutes to complete. Scores on each item are added together to provide an overall profile for health related quality of life, as well as for each dimension. The AQoL-8D was developed and validated in Australia with a large sample of adults, aged 16-74 (Maxwell et al., 2016).

The Patient Global Impressions Scale (PGI)* is a self-report, single item measure that aims to evaluate patients' perceptions of their health and assesses if there has been an improvement or decline in clinical status (Guy, 1976). The participant has to select the one response from the response options that gives the most accurate description of his/her state of health (overall status). The scale is widely validated for use measuring treatment for chronic pain (e.g. Farrar, Young, La Moreaux, Werth & Poole, 2001), and the manual indicates that it can be applied across a range of conditions (Guy, 1976).

Statistical methods / analysis
Quantitative data will be entered into SPSS, and the study hypotheses will be tested with the linear mixed effects models to compensate for expected attrition over time. In these models, the dependent variable is the DASS-21, with predictors being Time, Group and the Interaction between Time and Group - the coefficient for Interaction being the formal test of the hypothesis. The alpha level for all analyses will be set at .05.
