Brief Summary

Mindfulness-Based Cognitive Therapy (MBCT) is effective in reducing relapse rates and (residual) symptoms in major depressive disorder (MDD). However, the mechanisms underlying those MBCT-induced effects are far from clear. The goal of this study is to get more insight into the working mechanisms of MBCT. The main question to be answered is whether MBCT-induced reduction in depressive symptoms is mediated and/or moderated by repetitive negative thinking (RNT), or other factors hypothesized to be involved in the working mechanism of MBCT (e.g. mindfulness skills and self-compassion).

Outcome Measures

Primary Outcomes (3)

  • Depressive symptoms

    Measured with the Inventory of Depressive Symptomatology Self-Report (IDS-SR). The IDS-SR consists of 30 items. Scores range from 0-84. Higher scores indicate a higher severity of depression.

    Change from baseline to mid-treatment (4 weeks), to post-treatment (8 weeks)

  • Depressive rumination

    Measured with the brooding subscale of the Ruminative Response Scale (RRS). The brooding subscale consists of 5 items. Scores range from 5-20. Higher scores indicate a higher level of depressive rumination.

    Change from baseline to mid-treatment (4 weeks), to post-treatment (8 weeks)

  • Repetitive negative thinking (RNT)

    Measured by the Perseverative Thinking Questionnaire (PTQ). The PTQ consists of 15 items. Scores range from 0-60. Higher scores indicate a higher level of repetitive negative thinking.

    Change from baseline to mid-treatment (4 weeks), to post-treatment (8 weeks)

Secondary Outcomes (7)

  • Intrusive thoughts (state measure)

    Change from baseline to mid-treatment (4 weeks), to post-treatment (8 weeks)

  • Mindfulness Skills

    Change from baseline to mid-treatment (4 weeks), to post-treatment (8 weeks)

  • Anxiety Symptoms

    Change from baseline to mid-treatment (4 weeks), to post-treatment (8 weeks)

  • Overall functioning

    Change from baseline to mid-treatment (4 weeks), to post-treatment (8 weeks)

  • Self-compassion

    Change from baseline to mid-treatment (4 weeks), to post-treatment (8 weeks)

  • +2 more secondary outcomes

Other Outcomes (3)

  • Depressive symptoms

    Week-to-week change assessed after each MBCT session (up to 8 weeks) or weekly during wait-list (up to 8 weeks)

  • Non-judging mindfulness skill

    Week-to-week change assessed after each MBCT session (up to 8 weeks) or weekly during wait-list (up to 8 weeks)

  • Depressive rumination

    Week-to-week change assessed after each MBCT session (up to 8 weeks) or weekly during wait-list (up to 8 weeks)

Study Arms (2)

Mindfulness-Based Cognitive Therapy + Treatment as usual

Patients receive Mindfulness-Based Cognitive Therapy (MBCT) and treatment as usual (TAU). Measurements are administered before, half-way and after MBCT.

Behavioral: Mindfulness-Based Cognitive Therapy

Wait-list control (Treatment as usual)

Patients in the wait-list controlled group receive treatment us usual (TAU) during their waiting-period. After their waiting period, they receive MBCT in a similar fashion compared to the intervention group. Measurements are administered before, half-way and after their waiting period. In addition, a fourth and fifth measurement will be administered half-way and after MBCT.

Behavioral: Mindfulness-Based Cognitive Therapy

Interventions

MBCT will be offered according to the MBCT manual developed for relapse prevention in MDD (Zindel V. Segal, Williams, \& Teasdale, 2002). Thus, MBCT will consist of 8-weekly sessions of 2,5 hours, a 6-hour silent day, and daily home practice (± 45min). MBCT will be taught by a certified MBCT teacher meeting the advanced criteria of the Association of Mindfulness Based Teachers in the Netherlands and Flanders (Belgium) which are in concordance with the Good Practice guidelines of the UK Network of Mindfulness-Based Teacher Trainers (Crane et al., 2012).

Sampling MethodNon-Probability Sample
Study Population

Patients with chronic or recurrent MDD who are referred for MBCT at the RadboudUMC Centre for Mindfulness or at different locations of a local mental health institute (Pro Persona) will be recruited for the current study. Those patients will follow regular medical intake-procedures in accordance to procedures at the respective institutes and are screened for chronic or recurrent depression and other in- and exclusion criteria. Depression will be considered chronic if patients meet the DSM-V criteria of a 'persistent depressive disorder', which is combination of the 'chronic depressive disorder' and 'dysthymic disorder' as defined in the DSM-IV.

You may qualify if:

  • age ≥ 18
  • diagnosis of chronic or recurrent MDD according to DSM-V criteria, both current or remitted
  • able to give informed consent and perform experimental tasks

You may not qualify if:

  • in remission of first (not chronic) episode or having a first (not chronic) current episode
  • insufficient comprehension of the Dutch language
  • physical, cognitive, or intellectual impairments interfering with participation such as deafness, blindness, or sensorimotor handicaps
  • formerly involved in MBCT or MBSR or other 8-week Mindfulness-Based Intervention (MBI)
  • meets criteria for bipolar disorder, schizophrenia, schizophreniform disorder, schizoaffective illness or anorexia nervosa
  • current psychosis
  • high level of suicidality
  • drug or alcohol addiction in the past 6 months.
