Background: Studies of rumination suggest that self-focused attention is maladaptive and perpetuates depression. Conversely, self-focused attention can be adaptive, facilitating self-knowledge and the development of the alternative functional interpretations of negative thoughts and feelings on which cognitive therapy of depression depends. Increasing evidence suggests there are distinct varieties of self-focus, each with distinct functional properties. This study tested the prediction that in depressed patients brief inductions of analytical versus experiential self-focus would differentially affect overgeneral autobiographical memory, a phenomenon associated with poor clinical course. It was predicted that, relative to analytical self-focus, experiential self-focus would reduce overgeneral memory. Methods: 28 depressed patients either thought analytically about, or focused on their momentary experience of, identical symptom-focused induction items from [Cogn. Emotion 7 (1993) 561] rumination task. Participants completed the Autobiographical Memory Test [J. Abnorm. Psychol. 95 (1986) 144] before and after self-focus manipulations. Results: Experiential self-focus reduced overgeneral memory compared to analytical self-focus. Analytical and experiential self-focus did not differ in their effects on mood. Limitations: In the absence of a reference condition, only conclusions concerning the relative effects of analytical and experiential self-focus can be made. Conclusions: Results (1) support the differentiation of self-focus into distinct modes of self-attention with distinct functional effects in depression; (2) provide further evidence for the modifiability of overgeneral memory; and (3) provide further evidence for the dissociation of overgeneral memory and depressed mood. Clinically, results support the usefulness of training recovered depressed patients in adaptive experiential forms of self-awareness, as in mindfulness-based cognitive therapy.
IMPORTANCE:Relapse prevention in recurrent depression is a significant public health problem, and antidepressants are the current first-line treatment approach. Identifying an equally efficacious nonpharmacological intervention would be an important development.
OBJECTIVE:
To conduct a meta-analysis on individual patient data to examine the efficacy of mindfulness-based cognitive therapy (MBCT) compared with usual care and other active treatments, including antidepressants, in treating those with recurrent depression.
DATA SOURCES:
English-language studies published or accepted for publication in peer-reviewed journals identified from EMBASE, PubMed/Medline, PsycINFO, Web of Science, Scopus, and the Cochrane Controlled Trials Register from the first available year to November 22, 2014. Searches were conducted from November 2010 to November 2014.
STUDY SELECTION:
Randomized trials of manualized MBCT for relapse prevention in recurrent depression in full or partial remission that compared MBCT with at least 1 non-MBCT treatment, including usual care.
DATA EXTRACTION AND SYNTHESIS:
This was an update to a previous meta-analysis. We screened 2555 new records after removing duplicates. Abstracts were screened for full-text extraction (S.S.) and checked by another researcher (T.D.). There were no disagreements. Of the original 2555 studies, 766 were evaluated against full study inclusion criteria, and we acquired full text for 8. Of these, 4 studies were excluded, and the remaining 4 were combined with the 6 studies identified from the previous meta-analysis, yielding 10 studies for qualitative synthesis. Full patient data were not available for 1 of these studies, resulting in 9 studies with individual patient data, which were included in the quantitative synthesis.
RESULTS:
Of the 1258 patients included, the mean (SD) age was 47.1 (11.9) years, and 944 (75.0%) were female. A 2-stage random effects approach showed that patients receiving MBCT had a reduced risk of depressive relapse within a 60-week follow-up period compared with those who did not receive MBCT (hazard ratio, 0.69; 95% CI, 0.58-0.82). Furthermore, comparisons with active treatments suggest a reduced risk of depressive relapse within a 60-week follow-up period (hazard ratio, 0.79; 95% CI, 0.64-0.97). Using a 1-stage approach, sociodemographic (ie, age, sex, education, and relationship status) and psychiatric (ie, age at onset and number of previous episodes of depression) variables showed no statistically significant interaction with MBCT treatment. However, there was some evidence to suggest that a greater severity of depressive symptoms prior to treatment was associated with a larger effect of MBCT compared with other treatments.
CONCLUSIONS AND RELEVANCE:
Mindfulness-based cognitive therapy appears efficacious as a treatment for relapse prevention for those with recurrent depression, particularly those with more pronounced residual symptoms. Recommendations are made concerning how future trials can address remaining uncertainties and improve the rigor of the field.
There is encouraging evidence that structured psychological treatments for depression, in particular cognitive therapy, can reduce subsequent relapse after the period of initial treatment has been completed. However, there is a continuing need for prophylactic psychological approaches that can be administered to recovered patients in euthymic mood. An information-processing analysis of depressive maintenance and relapse is used to define the requirements for effective prevention, and to propose mechanisms through which cognitive therapy achieves its prophylactic effects. This analysis suggests that similar effects can be achieved using techniques of stress-reduction based on the skills of attentional control taught in mindfulness meditation. An information-processing analysis is presented of mindfulness and mindlessness, and of their relevance to preventing depressive relapse. This analysis provides the basis for the development of Attentional Control Training, a new approach to preventing relapse that integrates features of cognitive therapy and mindfulness training and is applicable to recovered depressed patients.
All over the world, research has shown that Mindfulness-Based Cognitive Therapy (MBCT) can halve the risk of future clinical depression in people who have already been depressed several times. Its effects seem comparable to antidepressant medications. But how?
Decentering is defined as the ability to observe one's thoughts and feelings as temporary, objective events in the mind, as opposed to reflections of the self that are necessarily true. The Experiences Questionnaire (EQ) was designed to measure both decentering and rumination but has not been empirically validated. The current study investigated the factor structure of the EQ in both undergraduate and clinical populations. A single, unifactorial decentering construct emerged using 2 undergraduate samples. The convergent and discriminant validity of this decentering factor was demonstrated in negative relationships with measures of depression symptoms, depressive rumination, experiential avoidance, and emotion regulation. Finally, the factor structure of the EQ was replicated in a clinical sample of individuals in remission from depression, and the decentering factor evidenced a negative relationship to concurrent levels of depression symptoms. Findings from this series of studies offer initial support for the EQ as a measure of decentering.
Metacognitive awareness is a cognitive set in which negative thoughts/feelings are experienced as mental events, rather than as the self. The authors hypothesized that (a) reduced metacognitive awareness would be associated with vulnerability to depression and (b) cognitive therapy (CT) and mindfulness-based CT (MBCT) would reduce depressive relapse by increasing metacognitive awareness. They found (a) accessibility of metacognitive sets to depressive cues was less in a vulnerable group (residually depressed patients) than in nondepressed controls; (b) accessibility of metacognitive sets predicted relapse in residually depressed patients; (c) where CT reduced relapse in residually depressed patients, it increased accessibility of metacognitive sets; and (d) where MBCT reduced relapse in recovered depressed patients, it increased accessibility of metacognitive sets. CT and MBCT may reduce relapse by changing relationships to negative thoughts rather than by changing belief in thought content.

The development of the Mindfulness‐Based Cognitive Therapy Adherence Scale (MBCT‐AS) is described. This 17‐item scale measures therapist adherence to the treatment protocol for Mindfulness‐Based Cognitive Therapy (MBCT), a treatment for the prevention of recurrence in Major Depressive Disorder. The MBCT‐AS assesses therapist behaviours specific to (MBCT) as well as therapy practices that MBCT shares with Cognitive Behaviour Therapy (CBT). To determine the utility of this scale, we compared delivery of group MBCT against group CBT, with independent ratings of taped sessions provided to measure adherence to MBCT and CBT for therapists in both groups. The results showed that: (a) raters can reliably use the MBCT‐AS; (b) MBCT therapists demonstrated adherence to the treatment protocol, as measured by the MBCT‐AS; and (c) MBCT is distinguishable from CBT on both the MBCT‐AS and a scale measuring adherence to CBT (CBT‐AS). These findings indicate that the MBCT‐AS may be a useful tool for ensuring the proper delivery of MBCT in future research, and may be helpful in determining the elements of MBCT that are unique to that treatment.
This book presents an innovative eight-session program that has been clinically proven to bolster recovery from depression and prevent relapse. Developed by leading scientist-practitioners, and solidly grounded in current psychological research, the approach integrates cognitive therapy principles and practice into a mindfulness framework. Clinicians from any background will find vital tools to help clients maintain gains made by prior treatment and to expand the envelope of care to remission and beyond. The focus of mindfulness-based cognitive therapy is teaching clients how to make a simple yet radical shift in their relationship to the thoughts, feelings, and bodily sensations that contribute to depressive relapse. This shift entails fostering a "decentered" relationship to experience, in which negative thoughts or feelings can be viewed as events in the mind, rather than as "self" or as necessarily true. Step-by-step guidelines are provided for conducting awareness exercises and cognitive interventions that help clients both gain awareness of mild states of sadness and prevent them from spiraling out of control. Illustrative transcripts and a wealth of reproducible materials, including session summaries and participant forms, enhance the clinical utility of the volume.

Recovered recurrently depressed patients were randomized to treatment as usual (TAU) or TAU plus mindfulness-based cognitive therapy (MBCT). Replicating previous findings, MBCT reduced relapse from 78% to 36% in 55 patients with 3 or more previous episodes; but in 18 patients with only 2 (recent) episodes corresponding figures were 20% and 50%. MBCT was most effective in preventing relapses not preceded by life events. Relapses were more often associated with significant life events in the 2-episode group. This group also reported less childhood adversity and later first depression onset than the 3-or-more-episode group, suggesting that these groups represented distinct populations. MBCT is an effective and efficient way to prevent relapse/recurrence in recovered depressed patients with 3 or more previous episodes.
This acclaimed work, now in a new edition, has introduced tens of thousands of clinicians to mindfulness-based cognitive therapy (MBCT) for depression, an 8-week program with proven effectiveness. Step by step, the authors explain the "whys" and "how-tos" of conducting mindfulness practices and cognitive interventions that have been shown to bolster recovery from depression and prevent relapse. Clinicians are also guided to practice mindfulness themselves, an essential prerequisite to teaching others. Forty-five reproducible handouts are included. Purchasers get access to a companion website featuring downloadable audio recordings of the guided mindfulness practices (meditations and mindful movement), plus all of the reproducibles, ready to download and print in a convenient 8 1/2" x 11" size. A separate website for use by clients features the audio recordings only. New to This Edition *Incorporates a decade's worth of developments in MBCT clinical practice and training. *Chapters on additional treatment components: the pre-course interview and optional full-day retreat. *Chapters on self-compassion, the inquiry process, and the three-minute breathing space. *Findings from multiple studies of MBCT's effectiveness and underlying mechanisms. Includes studies of adaptations for treating psychological and physical health problems other than depression. *Audio files of the guided mindfulness practices, narrated by the authors, on two separate Web pages--one for professionals, together with the reproducibles, and one just for clients. See also the authors' related titles for clients: The Mindful Way through Depression demonstrates these proven strategies in a self-help format, with in-depth stories and examples. The Mindful Way Workbook gives clients additional, explicit support for building their mindfulness practice, following the sequence of the MBCT program. Plus, for professionals: Mindfulness-Based Cognitive Therapy with People at Risk of Suicide extends and refines MBCT for clients with suicidal depression.
Previous research on depressed and suicidal patients and those with posttraumatic stress disorder has shown that patients' memory for the past is overgeneral (i.e., patients retrieve generic summaries of past events rather than specific events). This study investigated whether autobiographical memory could be affected by psychological treatment. Recovered depressed patients were randomly allocated to receive either treatment as usual or treatment designed to reduce risk of relapse. Whereas control patients showed no change in specificity of memories recalled in response to cue words, the treatment group showed a significantly reduced number of generic memories. Although such a memory deficit may arise from long-standing tendencies to encode and retrieve events generically, such a style is open to modification.

Evidence suggests mindfulness‐based clinical interventions are effective. Accepting this, we caution against assuming that mindfulness can be applied as a generic technique across a range of disorders without formulating how the approach addresses the factors maintaining the disorder in question. Six specific issues are raised: mindfulness has been found to be unhelpful in some contexts; where mindfulness has been found to be effective, instructors have derived and shared with clients a clear problem formulation; there may be many dimensions of effectiveness underlying the apparent simplicity of mindfulness; mindfulness was developed within a particular “view” of emotional suffering that implies wider changes that go beyond meditation practice alone; professionals need to match the different components of mindfulness with the psychopathology being targeted; nonetheless, mindfulness may affect processes common to different pathologies.
