- ACRONYM
- hypothesisWe hypothesize that compared to treatment as usual (TAU), Yoga-based Therapy (YBT)+TAU will lead to:

Hypothesis 1: Greater reductions in depressive symptoms, assessed with (a) clinician-administered measures (Hamilton Depression Rating Scale) and (b) self-report measures (Depression Anxiety Stress Scales). Group differences will be examined at post-treatment and 6- and 12-month follow up.

Hypothesis 2: A reduction of societal costs and improved health outcomes (assessed with QALYs).

Secondary hypotheses: (1) The benefits of YBT on depression will be partially mediated by (a) reduced brooding about the causes and consequences of negative events and moods and (b) reduced self-criticism/increased self-compassion after perceived failures; and (2) The YBT group will show greater increases in physical health and psychological well-being (e.g., positive emotion, life satisfaction, and perceived ability to manage one’s life).

Exploratory analyses: We will examine whether the effects of YBT are moderated by demographic variables (e.g., socioeconomic status) clinical factors (e.g., co-morbidity) and variables from the process evaluation (e.g., treatment adherence).

- InterventionsThe intervention will consist of manualized YBT administered in 9 weekly 90-minute group sessions with home practice +TAU. TAU will consist of interventions recommended by the Dutch guidelines for depression, including psychotherapy, pharmacotherapy, psychosocial support by psychiatric nurses, or some combination of these.
- Primary outcomePrimary outcome measures will consist of clinician-administered and self-report measures of depression symptoms. Quality-Adjusted Life Years will be used as primary outcome measure in the economic analysis.
- Secondary outcomeSecondary hypotheses will also be examined. Potential mediators of YBT will be assessed, including (a) ability to disengage attention from information regarding the causes and consequences of negative events and moods, measured by self-report and a computerized measure of attentional bias and (b) reduced self-criticism (and increased self-compassion) after perceived failure, measured by self-report and a computerized measure of self-concept. Also, the influence of YBT on symptom interference in daily functioning, quality of life and physical health and positive psychological functioning (i.e., positive emotion and quality of relationships) will be assessed.
- TimepointsAssessments are completed at pre- and post-intervention (or equivalent time period in TAU), and at 6- and 12-month follow-up.

- Brief summaryRationale: Major Depressive Disorder (MDD) is widespread, as nearly one in five Dutch will experience the disorder within their lifetime. In addition to individual suffering, MDD creates great economic costs in the Netherlands and is a leading contributor to the national disease burden. Although first-step interventions can be helpful, many individuals with MDD do not seek treatment and current interventions often fail to prevent the development of chronic, relapsing MDD. There is thus a pressing need to develop and test new interventions for depression. This need is particularly urgent in young adult women, as this population is especially vulnerable to developing MDD. Yoga-based interventions represent an innovative approach with great potential for treating depression. The rationale of using yoga as a MDD intervention in young women includes initial findings that yoga reduces depressive affect and yoga’s appeal in this population. Although the initial findings are promising, previous research has a number of methodological limitations such as insufficient statistical power, inadequate control groups, and short follow-up periods. The proposed project is designed to use rigorous methods to examine yoga as a treatment for acute depression and as means of preventing the transition to a chronic, relapsing disorder in a sample of young women. Objective: To examine whether adding yoga-based therapy (YBT) to treatment as usual (TAU) for young women with MDD leads to (1) greater reductions in symptoms and (2) greater cost-effectiveness in that the economic benefits of adding YBT to TAU outweigh the costs.
Hypothesis: Primary hypotheses are that compared both to TAU, YBT (+TAU) will show greater long-term (H1.1) reductions in clinician-administered (Hamilton Depression and Anxiety Rating Scales) and self-report (Depression Anxiety Stress Scales) measures of depression and (H1.2) cost-effectiveness. Secondary hypotheses are that YBT effects are partially mediated by cognitive mechanisms, including (H2.1) brooding and (H2.2) self-criticism. Exploratory analyses will examine potential moderators of YBT.
Study design: The study will consist of a randomized controlled trial comparing YBT+TAU with TAU. Assessments are completed at pre- and post-intervention (or equivalent time period in TAU), and at 6- and 12-month follow-up.
Study population: Young adult women (age 18-34 years) with a primary diagnosis of MDD. Intervention (if applicable): The intervention will consist of manualized YBT administered in 9 weekly 90-minute group sessions with home practice +TAU. TAU will consist of interventions recommended by the Dutch guidelines for depression, including psychotherapy, pharmacotherapy, psychosocial support by psychiatric nurses, or some combination of these.
Main study parameters/endpoints: Primary outcome measures will consist of clinician-administered and self-report measures of depression symptoms. Quality-Adjusted Life Years will be used as primary outcome measure in the economic analysis.
