The impact of mindfulness therapy combined with mentalization-based family therapy on suicidal ideation in adolescents with depressive disorder: randomized intervention study

BACKGROUND

Adolescents with depression who engage in non-suicidal self harming behaviors are more likely to adopt negative coping strategies when faced with negative events. Therefore, these patients should be introduced to positive coping strategies. Evidences have showed that mindfulness-based interventions can positively impact the psychology of patients with mental disorders. This study was to explore the impact of a combination of mindfulness therapy and mentalization-based family therapy (MBFT) on suicidal ideation in adolescents with depressive disorder.

METHODS

Eighty adolescent patients with depression and suicidal ideation admitted to our hospital from September 2021 to February 2022 were selected as subjects. They were divided into a control group and a study group using the random number table method, with each group comprising 40 subjects. The control group received MBFT, whereas the study group received both mindfulness therapy and MBFT. The psychological status and suicidal ideations of the two groups were compared before and after the intervention.

RESULTS

The psychological health scores of both groups of patients were lower after the intervention, with the scores of the study group being lower than those of the control group (P < 0.05). The scores on the suicidal ideation scales for both groups were lower after intervention, and the study group scored lower than the control group (P < 0.05). The absolute values of the differences in psychological health scale scores and suicidal ideation scale scores before and after the intervention were higher in the study group than in the control group (P < 0.05).

CONCLUSION

The combination of mindfulness therapy and MBFT can improve the psychological condition of adolescents with depression, reduce their suicidal ideations, and help them develop a healthy and positive outlook toward life, making this method worthy of clinical recommendation.

Mindfulness-based cognitive therapy versus psychoeducational intervention in bipolar outpatients: Results from a randomized controlled trial

INTRODUCTION

Few controlled trials have assessed the impact of Mindfulness Based Cognitive Therapy (MBCT) on symptoms and functioning in bipolar disorder (BD). This study aims to evaluate the effectiveness of MBCT adjunctive group treatment.

MATERIAL AND METHODS

Randomized, prospective, multicenter, single-blinded trial that included BP-outpatients with subthreshold depressive symptoms. Participants were randomly assigned to three arms: treatment as usual (TAU); TAU plus psychoeducation; and TAU plus MBCT. Primary outcome was change in Hamilton-D score; secondary endpoints were change in anxiety, hypo/mania symptoms and functional improvement. Patients were assessed at baseline (V1), 8 weeks (V2) and 6 months (V3). Main hypothesis was that adjunctive MBCT would improve depressive symptoms more than psychoeducation.

RESULTS

Eighty-four participants were recruited (MBCT=40, Psychoeducation=34, TAU=10). Depressive symptoms improved in the three arms between V1 and V2 (p<0.0001), and between V1 and V3 (p<0.0001), and did not change between V2 and V3. At V3 no significant differences between groups were found. There were no significant differences in other measures either.

CONCLUSIONS

In our BD population we did not find superiority of adjunctive MBCT over adjunctive Psychoeducation or TAU on subsyndromal depressive symptoms; neither on anxiety, hypo/mania, relapses, or functioning.

Mindfulness-based and mindfulness-informed interventions in bipolar disorder: a meta-analysis based on Becker's method

Bipolar disorder is a highly disruptive and debilitating problem. Mindfulness-based and mindfulness-informed interventions have exponentially emerged as third-generation therapies, applied to a wide spectrum of disorders, including bipolar disorder. However, the reviews and meta-analyses published to date are limited in their conclusions, as they are based on single-group pretest-posttest cohort designs and mostly focused on mindfulness-based interventions. The present review and meta-analysis try to address these limitations, including studies on informed mindfulness, controlled and single group designs. It used a specific meta-analytical procedure that allows an imputation procedure in those designs lacking a comparison group, by means of separate omnibus tests for the experimental and control group. A total of 13 studies (N = 331) were selected. The results showed an absence of effects on depression (g = 0.21) and mania (g = -0.13), but significant moderate effect on anxiety (g = 0.53). In conclusion, both mindfulness interventions showed robust evidence on anxiety symptoms in pretest-posttest periods compared to control groups. Few studies and lack of evidence of follow-up periods were the main limitations found.

Mindfulness-based cognitive therapy efficacy in reducing physiological response to emotional stimuli in patients with bipolar I disorder and the intermediate role of cognitive reactivity

OBJECTIVES

This study aims to investigate the impact of Mindfulness-Based Cognitive Therapy (MBCT) for bipolar disorders on emotional responses by using skin conductance recording, and to investigate a mediating or predictive effect of cognitive reactivity.

METHODS

Sixty-seven patients with bipolar disorder were assessed at baseline, pre-MBCT and post-MBCT. After answering inventories regarding depression and dysfunctional attitudes, they were instructed to focus on emotional pictures from the International Affective Pictures System while electrodermal recording.

RESULTS

For a subgroup of patients having a significant change of the electrodermal response, MBCT reduced dysfunctional attitudes and the amplitude of the physiological response to negative stimuli. Findings also show that lower dysfunctional attitudes at baseline predicted a larger reduction of physiological reactivity.

CONCLUSIONS

MBCT could decrease patient's reactivity to negative stimuli by decreasing its physiological component, which is coherent with its aim to facilitate disengaging from affective stimuli. Further studies are needed to better understand the mechanisms involved and how this could translate in reducing the risk of relapse.

Thought Process Evolved From Rigid to Flexible in a Patient With Bipolar Disorder Via "Return to Work Program": A Case Report

ABSTRACT

In the working population, bipolar disorder can have a significant negative effect on professional relationships, attendance, functioning, and loss of productivity. In Japan, workers who take a leave due to depressive episodes receive a work-focused intervention program called the "return to work program" during their leave. A 39-year-old Japanese woman with bipolar II disorder took a third sick leave of absence. We recommended her the return to work program of our university hospital. At the beginning of the program, she had a rigid thought process toward her perceptions of her duties in the workplace and at home. Through the program, mindfulness might identify rigidity, group cognitive-behavioral therapy might correct rigidity, and self-analysis might have regained flexibility. In conclusion, a variety of effects of our return to work program might have enabled her thought process to evolve from rigid to flexible, and she showed successful reinstatement.

Role of autobiographical memory in the impact of MBCT on dysfunctional attitudes, depressive symptoms and anxiety in bipolar I patients

BACKGROUND

The literature suggests that cognitive reactivity in bipolar patients can increase relapse vulnerability, is enhanced by depressive mood and dysfunctional attitudes, and could be improved with MBCT. Autobiographical memory (AM) could be involved in cognitive reactivity, and improved with MBCT training. This study aims to investigate the effect of MBCT for bipolar patients on depressive and anxious symptoms, dysfunctional attitudes and AM, and the predictive versus mediating role of AM in the impact of MBCT on clinical symptoms.

METHODS

Sixty-two outpatients diagnosed with bipolar I disorder were assigned to MBCT and were compared to 37 bipolar patients on a waiting list. Affective symptoms and dysfunctional attitudes were explored using self-report inventories (BDI, BAI, DAS) and AM was assessed using the Autobiographical Memory Test.

RESULTS

Patients receiving MBCT demonstrated significantly decreased depressive symptoms, dysfunctional attitudes, overgeneral memories and omissions, and increased specific memories. General AM and omissions at baseline respectively predicted lower anxiety and dysfunctional attitudes improvement following therapy, but the improvement of AM did not explain the impact of MBCT on depression and dysfunctional attitudes improvement.

LIMITS

Further studies should consider patients' therapeutic adherence and mechanisms involved in MBCT in order to better apprehend how MBCT may reduce dysfunctional attitudes and improve AM in bipolar patients.

CONCLUSION

Results are consistent with the hypothesis that MBCT reduces cognitive reactivity and AM impairment in bipolar disorders. Findings suggest that AM training prior to MBCT may influence MBCT efficacy, but that MBCT efficacy on AM and clinical symptoms are non-related phenomena.

Mindfulness-based cognitive therapy for bipolar disorder: A systematic review and meta-analysis

BACKGROUND

Mindfulness-based cognitive therapy (MBCT) is an increasingly popular treatment for major depression and anxiety disorder, but has shown inconsistent efficacy for bipolar disorder (BD). Therefore, we conducted a meta-analysis to assess the general efficacy of MBCT for BD.

METHODS

Ten studies were identified that fulfilled the current inclusion criteria, including three controlled and seven uncontrolled studies. The effects of MBCT on depression, anxiety, mania, stress, mindfulness ability, and emotional regulation were assessed by comparing psychometric scale scores within groups (pre- vs. post-intervention) across trials as well as between groups (control vs. MBCT) across controlled trials.

RESULTS

Within-group comparison revealed a reduction in symptoms of depression (g = 0.37, 95%CI = 0.09-0.64, P = 0.009) and anxiety (g = 0.45, 95%CI =0.16-0.75, P = 0.002) following treatment compared to baseline. Stress symptoms were also significantly reduced (g = 0.39, 95%CI = 0.09-0.69, P = 0.01), mindfulness ability (g = 0.63, 95%CI = 0.39-0.87, P<0.00001) and emotion regulation (g = 0.62, 95%CI=0.14-1.10, P = 0.01) were significantly improved compared to baseline. However, symptoms of mania were not alleviated (g=-0.26, 95%CI=-1.43-0.91, P = 0.66). Subgroup analysis indicated that symptoms of depression and anxiety were still significantly improved at 3 months post-intervention (g = 0.46, 95%CI = 0.13-0.80, P = 0.006 and g = 0.57, 95%CI = 0.21-0.94, P = 0.002, respectively) but not at 12 months (g = 0.04, 95%CI = -0.29-0.37, P = 0.82 and g = 0.17, 95%CI =-0.16-0.50, P = 0.31). In between-groups analysis of controlled studies, MBCT significantly reduced depressive symptoms (g = 0.3, 95%CI =-0.05-0.65, P = 0.09) but not anxiety symptoms (g = 0.51, 95%CI =  -0.20-1.22, P = 0.16).

CONCLUSION

Mindfulness-based cognitive therapy appears effective for alleviation of depression and anxiety among BD patients, possibly by improving emotional regulation and mindfulness abilities. However, efficacy appears time-limited and inconsistent, necessitating additional larger-scale studies and the development of post-intervention programs for sustained efficacy.

Effect of a Mindfulness-Based Intervention Program on Comprehensive Mental Health Problems of Chinese Undergraduates

How best to support mental health of young people is an important public health challenge. More empirical researches are need to examine the relationship between mindfulness-based interventions and mental health in China. The present study reports results from a quasi-experiment following a one-group repeated-measures design which investigated the impact of a standard 8-week mindfulness-based cognitive therapy (MBCT) program in 81 Chinese undergraduates (14 males, 67 females, age 20.35 ± 1.35 years). Data was collected using the Symptom Check List 90 (SCL90) at baseline, week 3, week 6 and week 8 in order to examine the trajectory of mental health changes during the MBCT training. The repeated measures analysis of variance showed that the decrease was significant in the scores of somatization (F = 13.432, P < 0.01), obsessive-compulsive symptoms (F = 43.954, P < 0.01), interpersonal sensitivity (F = 36.196, P < 0.01), depression (F = 25.914, P < 0.01), anxiety (F = 26.547, P < 0.01), hostility (F = 19.707, P < 0.01), phobic anxiety (F = 21.145, P < 0.01), paranoid ideation (F = 19.857, P < 0.01) and psychoticism (F = 32.833, P < 0.01). The findings from the present study show that a standard MBCT program may have positive impact on reduction in mental health problems in Chinese undergraduates. Further controlled studies with randomized designs are needed to investigate these promising results in more depth.

Financial difficulties in bipolar disorder part 2: psychological correlates and a proposed psychological model

OBJECTIVES

A number of psychological variables have been shown to be prominent in bipolar disorder. However, no research has looked at the relationship between financial difficulties and psychological factors in bipolar disorder.

AIMS

This study aims to look at the relationship between financial difficulties and psychological factors in bipolar disorder.

METHOD

Fifty-four participants with diagnosis of bipolar disorder in an adult secondary care NHS mental health service completed the questionnaire pack which included measures examining financial variables including difficulty paying bills and perceived financial wellbeing. Questionnaires measured self-esteem, impulsivity, mindfulness and dysfunctional attitudes.

RESULTS

Financial difficulties cross-sectionally were related to a number of psychological variables such as mindfulness and impulsivity. Over time, the strongest effects were for compulsive spending which was increased over time by higher dependency and achievement cognitions, lower mindfulness and lower self-esteem. Poor perceived financial wellness lower self-esteem over time. A psychological model incorporating these and related findings is presented.

CONCLUSION

Psychological factors appear to be related to financial difficulties in bipolar disorder. Future research is needed to confirm the model presented here and develop interventions.

Effectiveness of Psychotherapy on Suicidal Risk: A Systematic Review of Observational Studies

Background: Suicidal behavior is a major public health concern worldwide, and the interest in the development of novel and more efficient treatment strategies and therapies to reduce suicidal risk is increasing. Some recent studies have summarized the results of randomized clinical trials (RCTs) assessing the efficacy of psychotherapeutic tools designed to treat patients at suicidal risk. However, observational studies, which reflect real-world effectiveness and may use original approaches, have not been reviewed. Method: The aim of this study is to systematically review the available scientific evidence issued from observational studies on the clinical effectiveness of psychotherapeutic tools designed to treat patients at suicide risk. We have thus performed a systematic search of PubMed and Web of Science databases. Results: Out of 1578 papers, 40 original observational studies fulfilled our selection criteria. The most used psychotherapeutic treatments were dialectical behavioral therapy (DBT, 27.5%) and cognitive behavioral therapy (CBT, 15.0%) in patients with a diagnosis of borderline personality disorder (32.5%) and depression (15.0%). Despite the between-study heterogeneity, interventions lead to a reduction in suicidal outcomes, i.e., suicidal ideation (55.0%) and suicide attempts (37.5%). The content and reporting quality varied considerably between the studies. Conclusion: DBT and CBT are the most widely used psychotherapeutic interventions and show promising results in existing observational studies. Some of the included studies provide innovative approaches. Group therapies and internet-based therapies, which are cost-effective methods, are promising treatments and would need further study.

Mindfulness-based cognitive therapy for bipolar disorder: A systematic review

BACKGROUND

Persisting high levels of relapse, morbidity and mortality in bipolar disorder (BD) in spite of first-line, evidence-based psychopharmacology has spurred development and research on adjunctive psychotherapies. Mindfulness-based cognitive therapy (MBCT) is an emerging psychotherapy that has shown benefit in related and comorbid conditions such as major depressive, anxiety, and substance disorders. Furthermore, neurocognitive studies of MBCT suggest that it may have effects on some of the theorized pathophysiological processes in BD.

METHODS

We conducted a systematic literature review using PsychINFO and PubMed databases to identify studies reporting clinical and/or neurocognitive findings for MBCT for BD.

RESULTS

This search revealed 13 articles. There was a wide range in methodological quality and most studies were underpowered or did not present power calculations. However, MBCT did not appear to precipitate mania, and there is preliminary evidence to support a positive effect on anxiety, residual depression, mood regulation, and broad attentional and frontal-executive control.

LIMITATIONS

As meta-analysis is not yet possible due to study heterogeneity and quality, the current review is a narrative synthesis, and therefore net effects cannot be estimated.

CONCLUSIONS

MBCT for BD holds promise, but more high-quality studies are needed in order to ascertain its clinical efficacy. Recommendations to address the limitations of the current research are made.

The effectiveness of adjunct mindfulness-based intervention in treatment of bipolar disorder: A systematic review and meta-analysis

BACKGROUND

Mindfulness-based interventions (MBIs) have been increasingly used as an adjunctive treatment to pharmacotherapy for a few psychiatric disorders. However, few studies have investigated the efficacy of MBIs in bipolar disorder (BD).

METHODS

We performed a systematic review and meta-analysis to evaluate the efficacy of MBIs as an adjunctive treatment in BD. Major electronic databases were independently searched by two authors for controlled and uncontrolled studies which examined the effects of MBIs on psychiatric symptoms in subjects with BD. Data from original studies were synthesized by using a random effects model.

RESULTS

Twelve trials were eligible for inclusion into current meta-analysis, including three controlled studies (n=132) and nine uncontrolled studies (n=142). In within-group analysis, MBIs significantly reduced depressive (7 studies, n=100, Hedges' g=0.58, p<0.001) and anxiety (4 studies, n=68, Hedges' g=0.34, p=0.043) symptoms, but not manic symptoms (6 studies, n=89, Hedges' g=0.09, p=0.488) and cognition (3 studies, n=43, Hedges' g=0.35, p=0.171), compared to baseline. In between-group analysis (intervention group versus waiting list group, all patients with BD), MBIs did not reduce depressive (3 studies, n=132, Hedges' g=0.46, p=0.315) or anxiety (3 studies, n=132, Hedges' g=0.33, p=0.578) symptoms.

LIMITATIONS

Only three controlled trials compared MBIs to control conditions.

CONCLUSIONS

Our meta-analysis showed significantly beneficial effects on depressive and anxiety symptoms of BD patients in within-group analysis. However, this significance was not observed in comparison with the control groups. Further clinical trials are warranted to investigate the differences in the benefits of MBIs between treatment and control subjects.

"When my Moods Drive Upward There Is Nothing I Can Do about It": A Review of Extreme Appraisals of Internal States and the Bipolar Spectrum

The integrative cognitive model provides a comprehensive account of bipolar disorder (BD) that, if empirically supported, has important potential implications for psychological therapies. This article is the first to review the evidence for this model. We evaluate the evidence (up to 2017) for four hypotheses derived uniquely from the model: extreme positive and negative appraisals of internal states are associated with (1) risk of developing BD; (2) BD diagnosis; (3) relevant clinical and functional outcomes including hypomanic and depressive mood symptoms; and (4) outcomes over time. Research involving individuals with diagnosed mood disorders as well as non-clinical populations is reviewed. The hypotheses were broadly supported and several consistent findings were not accounted for by alternative psychological models of BD. The evidence base is limited by a relative paucity of prospective studies; only 6 of the 31 studies identified. Implications for theory, research and clinical practice are discussed.

Mindfulness-Based Treatment for Bipolar Disorder: A Systematic Review of the Literature

Despite the increasing number of studies examining the effects of mindfulness interventions on symptoms associated with Bipolar Disorder (BD), the effectiveness of this type of interventions remains unclear. The aim of the present systematic review was to (i) critically review all available evidence on Mindfulness Based Cognitive Therapy (MBCT) as a form of intervention for BD; (ii) discuss clinical implications of MBCT in treating patients with BD; and (iii) provide a direction for future research. The review presents findings from 13 studies (N = 429) that fulfilled the following selection criteria: (i) included BD patients; (ii) presented results separately for BD patients and control groups (where a control group was available); (iii) implemented MBCT intervention; (iv) were published in English; (v) were published in a peer reviewed journal; and (vi) reported results for adult participants. Although derived from a relatively small number of studies, results from the present review suggest that MBCT is a promising treatment in BD in conjunction with pharmacotherapy. MBCT in BD is associated with improvements in cognitive functioning and emotional regulation, reduction in symptoms of anxiety depression and mania symptoms (when participants had residual manic symptoms prior to MBCT). These, treatment gains were maintained at 12 month follow up when mindfulness was practiced for at least 3 days per week or booster sessions were included. Additionally, the present review outlined some limitations of the current literature on MBCT interventions in BD, including small study sample sizes, lack of active control groups and idiosyncratic modifications to the MBCT intervention across studies. Suggestions for future research included focusing on factors underlying treatment adherence and understanding possible adverse effects of MBCT, which could be of crucial clinical importance.

Reviewing Mindfulness-Based Interventions for Suicidal Behavior

This article describes the rationale for using mindfulness-based interventions (MBIs) to prevent suicidal behavior in high suicide-risk individuals. A narrative review of studies testing the feasibility of MBIs with individuals at risk for suicidal behavior and the effectiveness of MBIs for reducing suicidality was conducted. Studies testing the effectiveness of MBIs for reducing deficits specific to suicide attempters among depressed individuals were also reviewed as were studies examining moderators of MBI treatment adherence and effectiveness to the extent that these might suggest possible limitations to using MBIs with high suicide-risk individuals. Findings from the handful of available studies support targeting suicidal ideation with MBI. Additional studies show deficits associated with suicide attempt, namely attentional dyscontrol, problem solving deficits, and abnormal stress response, are improved by MBI and thus strengthen the rationale for using MBIs with high suicide-risk individuals.

Psychotherapeutic Treatment of Bipolar Depression

The gold standard for treating bipolar depression is based on the combination of mood stabilizers and psychotherapy. Therefore, the authors present evidence-based models and promising approaches for psychotherapy for bipolar depression. Cognitive-behavioral therapy, family focused therapy, interpersonal and social rhythm therapy, mindfulness-based cognitive therapy, and dialectical behavior therapy are discussed. Behavioral activation, the cognitive behavioral analysis system of psychotherapy, and the unified protocol as promising future directions are presented. This review informs medical providers of the most appropriate referral guidelines for psychotherapy for bipolar depression. The authors conclude with a decision tree delineating optimal referrals to each psychotherapy approach.

Parental Expressed Emotion and Youth Psychopathology: New Directions for an Old Construct

Levels of parental expressed emotion (EE) are prospectively associated with the symptomatic course of a range of childhood psychiatric disorders. This article reviews the literature linking parental EE to youth psychopathology and proposes a novel framework for understanding its mechanisms of action. We find that, despite noteworthy methodological limitations, parental EE is linked consistently to a more deleterious course of mood, anxiety, and psychotic disorders in youth. Its mechanism of action is unknown. Models of "toxic family stress" (referring to frequent, sustained, and uncontrollable stress without protective influences) provide one framework for understanding how high EE environments interact with individual biological vulnerabilities to promote illness onset and recurrence. Research aimed at understanding biological responses (e.g., stress reactivity, arousal) to familial EE is needed. Such work may inform efforts to understand how EE affects the course of psychiatric disorders and may guide the development of novel interventions emphasizing emotion regulation strategies.

Mindfulness-Based Cognitive Therapy for Perinatal Women with Depression or Bipolar Spectrum Disorder

The perinatal period is a high-risk time for mood deterioration among women vulnerable to depression. This study examined feasibility, acceptability, and improvement associated with mindfulness-based cognitive therapy (MBCT) in perinatal women with major depressive disorder (MDD) or bipolar spectrum disorder (BSD). Following a diagnostic evaluation, 39 perinatal women with a lifetime history of MDD (n = 27) or BSD (n = 12) enrolled in an 8-week program of MBCT classes (2 h each) that incorporated meditation, yoga, and mood regulation strategies. Participants were pregnant (n = 12), planning pregnancy (n = 11), or up to 1-year postpartum (n = 16). Participants were self-referred and most had subthreshold mood symptoms. Assessments of depression, (hypo)mania, and anxiety were obtained by interview and self-report at baseline, post-treatment and at 1- and 6-month post-treatment. Women with a history of MDD were more likely to complete the classes than women with BSD. Of 32 women who completed the classes, 7 (21.9 %) had a major depressive episode during the 6-month post-treatment follow-up. On average, participants with MDD reported improvements in depression from pre- to post-treatment. Mood improvement was not observed in the BSD group. In the full sample, improvements in depression symptoms across time points were associated with increasing mindful tendency scores. This study was limited by its uncontrolled design, heterogeneous sample, and questionnaire-based assessment of mindfulness skills. MBCT may be an important component of care for perinatal women with histories of major depression. Its applicability to perinatal women with BSD is unclear.

A Lifetime Prevalence of Comorbidity Between Bipolar Affective Disorder and Anxiety Disorders: A Meta-analysis of 52 Interview-based Studies of Psychiatric Population

BACKGROUND

Bipolar affective disorder has a high rate of comorbidity with a multitude of psychiatric disorders and medical conditions. Among all the potential comorbidities, co-existing anxiety disorders stand out due to their high prevalence.

AIMS

To determine the lifetime prevalence of comorbid anxiety disorders in bipolar affective disorder under the care of psychiatric services through systematic review and meta-analysis.

METHOD

Random effects meta-analyses were used to calculate the lifetime prevalence of comorbid generalised anxiety disorder, panic disorder, social anxiety disorder, specific phobia, agoraphobia, obsessive compulsive disorder and posttraumatic stress disorder in bipolar affective disorder.

RESULTS

52 studies were included in the meta-analysis. The rate of lifetime comorbidity was as follows: panic disorder 16.8% (95% CI 13.7-20.1), generalised anxiety disorder 14.4% (95% CI 10.8-18.3), social anxiety disorder13.3% (95% CI 10.1-16.9), post-traumatic stress disorder 10.8% (95% CI 7.3-14.9), specific phobia 10.8% (95% CI 8.2-13.7), obsessive compulsive disorder 10.7% (95% CI 8.7-13.0) and agoraphobia 7.8% (95% CI 5.2-11.0). The lifetime prevalence of any anxiety disorders in bipolar disorder was 42.7%.

CONCLUSIONS

Our results suggest a high rate of lifetime concurrent anxiety disorders in bipolar disorder. The diagnostic issues at the interface are particularly difficult because of the substantial symptom overlap. The treatment of co-existing conditions has clinically remained challenging.

How Does Mindfulness Meditation Work? Proposing Mechanisms of Action From a Conceptual and Neural Perspective

Cultivation of mindfulness, the nonjudgmental awareness of experiences in the present moment, produces beneficial effects on well-being and ameliorates psychiatric and stress-related symptoms. Mindfulness meditation has therefore increasingly been incorporated into psychotherapeutic interventions. Although the number of publications in the field has sharply increased over the last two decades, there is a paucity of theoretical reviews that integrate the existing literature into a comprehensive theoretical framework. In this article, we explore several components through which mindfulness meditation exerts its effects: (a) attention regulation, (b) body awareness, (c) emotion regulation (including reappraisal and exposure, extinction, and reconsolidation), and (d) change in perspective on the self. Recent empirical research, including practitioners' self-reports and experimental data, provides evidence supporting these mechanisms. Functional and structural neuroimaging studies have begun to explore the neuroscientific processes underlying these components. Evidence suggests that mindfulness practice is associated with neuroplastic changes in the anterior cingulate cortex, insula, temporo-parietal junction, fronto-limbic network, and default mode network structures. The authors suggest that the mechanisms described here work synergistically, establishing a process of enhanced self-regulation. Differentiating between these components seems useful to guide future basic research and to specifically target areas of development in the treatment of psychological disorders.

Online mindfulness-based intervention for late-stage bipolar disorder: pilot evidence for feasibility and effectiveness

OBJECTIVES

People in the late stage of bipolar disorder (BD) experience elevated relapse rates and poorer quality of life (QoL) compared with those in the early stages. Existing psychological interventions also appear less effective in this group. To address this need, we developed a new online mindfulness-based intervention targeting quality of life (QoL) in late stage BD. Here, we report on an open pilot trial of ORBIT (online, recovery-focused, bipolar individual therapy).

METHODS

Inclusion criteria were: self-reported primary diagnosis of BD, six or more episodes of BD, under the care of a medical practitioner, access to the internet, proficient in English, 18-65 years of age. Primary outcome was change (baseline - post-treatment) on the Brief QoL.BD (Michalak and Murray, 2010). Secondary outcomes were depression, anxiety, and stress measured on the DASS scales (Lovibond and Lovibond, 1993).

RESULTS

Twenty-six people consented to participate (Age M=46.6 years, SD=12.9, and 75% female). Ten participants were lost to follow-up (38.5% attrition). Statistically significant improvement in QoL was found for the completers, t(15)=2.88, 95% CI:.89-5.98, p=.011, (Cohen׳s dz=.72, partial η(2)=.36), and the intent-to-treat sample t(25)=2.65, 95% CI:.47-3.76, (Cohen׳s dz=.52; partial η(2)=.22). A non-significant trend towards improvement was found on the DASS anxiety scale (p=.06) in both completer and intent-to-treat samples, but change on depression and stress did not approach significance.

LIMITATIONS

This was an open trial with no comparison group, so measured improvements may not be due to specific elements of the intervention. Structured diagnostic assessments were not conducted, and interpretation of effectiveness was limited by substantial attrition.

CONCLUSION

Online delivery of mindfulness-based psychological therapy for late stage BD appears feasible and effective, and ORBIT warrants full development. Modifications suggested by the pilot study include increasing the 3 weeks duration of the intervention, adding cautions about the impact of extended meditations, and addition of coaching support/monitoring to optimise engagement.

[Review of the effects of mindfulness meditation on mental and physical health and its mechanisms of action]

Interventions based on mindfulness have become increasingly popular. This article reviews the empirical literature on its effects on mental and physical health, discusses presumed mechanisms of action as well as its proposed neurobiological underpinning. Mindfulness is associated with increased well-being as well as reduced cognitive reactivity and behavioral avoidance. It seems to contribute to enhance immune functions, diminish inflammation, diminish the reactivity of the autonomic nervous system, increase telomerase activity, lead to higher levels of plasmatic melatonin and serotonin. It enhances the quality of life for patients suffering from chronic pain, fibromylagia and HIV infection. It facilitates adaptation to the diagnosis of cancer and diabetes. It seems to lead to symptomatic improvement in irritable bowel syndrome, chronic fatigue syndrome, hot flashes, insomnia, stress related hyperphagia. It diminishes craving in substance abuse. The proposed mechanism of action are enhanced metacognitive conscience, interoceptive exposure, experiential acceptance, self-management, attention control, memory, relaxation. Six mechanism of actions for which neurological underpinnings have been published are: attention regulation (anterior cingulate cortex), body awareness (insula, temporoparietal junction), emotion regulation (modulation of the amygdala by the lateral prefrontal cortex), cognitive re-evaluation (activation of the dorsal medial prefrontal cortex or diminished activity in prefrontal regions), exposure/extinction/reconsolidation (ventromedial prefrontal cortex, hippocampus, amygdala) and flexible self-concept (prefrontal median cortex, posterior cingulated cortex, insula, temporoparietal junction). The neurobiological effects of meditation are described. These are: (1) the deactivation of the default mode network that generates spontaneous thoughts, contributes to the maintenance of the autobiographical self and is associated with anxiety and depression; (2) the anterior cingulate cortex that underpins attention functions; (3) the anterior insula associated with the perception of visceral sensation, the detection of heartbeat and respiratory rate, and the affective response to pain; (4) the posterior cingulate cortex which helps to understand the context from which a stimulus emerges; (5) the temporoparietal junction which assumes a central role in empathy and compassion; (6) the amygdala implicated in fear responses. The article ends with a short review of the empirical basis supporting the efficacy for mindfulness based intervention and suggested directions for future research.

A randomized controlled trial of mindfulness-based cognitive therapy for bipolar disorder

OBJECTIVE

To compare the efficacy of mindfulness-based cognitive therapy (MBCT) plus treatment as usual (TAU) to TAU alone for patients with bipolar disorder over a 12-month follow-up period.

METHOD

Participants with a DSM-IV diagnosis of bipolar disorder were randomly allocated to either MBCT plus TAU or TAU alone. Primary outcome measures were time to recurrence of a DSM-IV major depressive, hypomanic or manic episode; the Montgomery-Åsberg Depression Rating Scale (MADRS); and Young Mania Rating Scale (YMRS). Secondary outcome measures were number of recurrences, the Depression Anxiety Stress Scales (DASS), and the State Trait Anxiety Inventory (STAI).

RESULTS

Ninety-five participants with bipolar disorder were recruited to the study (MBCT = 48; TAU = 47). Intention-to-treat (ITT) analysis found no significant differences between the groups on either time to first recurrence of a mood episode or total number of recurrences over the 12-month period. Furthermore, there were no significant between-group differences on the MADRS or YMRS scales. A significant between-group difference was found in STAI - state anxiety scores. There was a significant treatment by time interaction for the DAS - achievement subscale.

CONCLUSION

While MBCT did not lead to significant reductions in time to depressive or hypo/manic relapse, total number of episodes, or mood symptom severity at 12-month follow-up, there was some evidence for an effect on anxiety symptoms. This finding suggests a potential role of MBCT in reducing anxiety comorbid with bipolar disorder.

La psychoéducation pour les troubles bipolaires : recension des écrits et recommandations pour le système de santé québécois

Le trouble bipolaire est une maladie chronique caractérisée par une récurrence des rechutes thymiques, et par des symptômes résiduels interférant avec le fonctionnement de l’individu. La pharmacothérapie demeure la pierre angulaire du traitement. Malheureusement, la médication a des effets limités sur certains aspects de la maladie, sans compter qu’une grande proportion de patients présente des problèmes d’observance à leur traitement pharmacologique. Cette recension des écrits aborde le rôle de la psychoéducation comme traitement complémentaire dans la prise en charge des patients bipolaires. Les différentes modalités de psychoéducation structurée, dont deux programmes psychoéducatifs manualisés appuyés par des données probantes, sont présentées. Dans une perspective de transfert des connaissances, des recommandations pour l’implantation de la psychoéducation dans le système de santé québécois sont proposées.

Mood regulation in youth: research findings and clinical approaches to irritability and short-lived episodes of mania-like symptoms

PURPOSE OF REVIEW

Mood regulation problems, such as severe chronic irritability or short episodes of mania-like symptoms, are common, impairing and a topic of intense recent interest to clinicians, researchers and the Diagnostic and Statistical Manual (DSM)-5 process. Here, we review the most recent findings about these two presentations and discuss the approaches to their treatment.

RECENT FINDINGS

Longitudinal and genetic findings suggest that chronic irritability should be regarded as a mood problem that is distinct from bipolar disorder. A proportion of children with short (less than 4 days) episodes of mania-like symptoms seem to progress to classical (Type I or II) bipolar disorder over time in the US clinic samples. In a UK sample, such episodes were independently associated with psychosocial impairment. The evidence base for the treatment of either irritability or short-lived episodes of mania-like symptoms is still small. Clinicians should be cautious with extrapolating treatments from classical bipolar disorder to these mood regulation problems. Cognitive and behavioural therapy (CBT)-based approaches targeting general mood regulation processes may be effective for cases with severe irritability or short episodes of mania-like symptoms.

SUMMARY

There is increasing research evidence for the importance of mood regulation problems in the form of either irritability or short episodes of mania-like symptoms in youth. The evidence base for their drug treatment has yet to be developed. CBT-based interventions to modify the processes of mood regulation may be a useful and well tolerated intervention for patients with these presentations.

"Mind the trap": mindfulness practice reduces cognitive rigidity

Two experiments examined the relation between mindfulness practice and cognitive rigidity by using a variation of the Einstellung water jar task. Participants were required to use three hypothetical jars to obtain a specific amount of water. Initial problems were solvable by the same complex formula, but in later problems ("critical" or "trap" problems) solving was possible by an additional much simpler formula. A rigidity score was compiled through perseverance of the complex formula. In Experiment 1, experienced mindfulness meditators received significantly lower rigidity scores than non-meditators who had registered for their first meditation retreat. Similar results were obtained in randomized controlled Experiment 2 comparing non-meditators who underwent an eight meeting mindfulness program with a waiting list group. The authors conclude that mindfulness meditation reduces cognitive rigidity via the tendency to be "blinded" by experience. Results are discussed in light of the benefits of mindfulness practice regarding a reduced tendency to overlook novel and adaptive ways of responding due to past experience, both in and out of the clinical setting.

Comorbid anxiety in bipolar spectrum disorders: a neglected research and treatment issue?

BACKGROUND

Anxiety disorders are highly prevalent among patients with bipolar disorder and have a substantial impact on the course of illness and response to treatment. Despite the substantial impact that comorbid anxiety disorders have on the prognosis of individuals with bipolar disorder, many aspects of this comorbidity have received little attention from researchers. This study aims to document the current state of the literature on the comorbidity between anxiety and bipolar disorders by analyzing publication trends on the subject.

METHOD

This study is a quantitative and qualitative review of articles on the comorbidity between anxiety disorders and bipolar disorder published between 1990 and 2010 in the ISI Web of Science, Medline and PsycINFO databases. The number of articles published each year on this comorbidity was calculated and compared to the literature published on bipolar disorder as a whole. Articles were classified into five categories and 13 subcategories to identify the main focuses of the literature and current gaps in the knowledge on the subject.

RESULTS

Interest in the comorbidity between anxiety disorders and bipolar disorder grew continually since 1990, but seems to have reached a plateau. The majority of articles addressing this comorbidity are descriptive in nature, with very few concrete studies examining the mechanisms and treatment approaches that might lead to positive advancements in the field.

LIMITATIONS

Articles written in languages other than English or French were not reviewed.

CONCLUSIONS

It is time to step up research efforts to better understand and manage this under-studied combination of disorders.

Mindfulness-based cognitive therapy: theory and practice

Mindfulness-based cognitive therapy (MBCT) incorporates elements of cognitive-behavioural therapy with mindfulness-based stress reduction into an 8-session group program. Initially conceived as an intervention for relapse prevention in people with recurrent depression, it has since been applied to various psychiatric conditions. Our paper aims to briefly describe MBCT and its putative mechanisms of action, and to review the current findings about the use of MBCT in people with mood and anxiety disorders. The therapeutic stance of MBCT focuses on encouraging patients to adopt a new way of being and relating to their thoughts and feelings, while placing little emphasis on altering or challenging specific cognitions. Preliminary functional neuroimaging studies are consistent with an account of mindfulness improving emotional regulation by enhancing cortical regulation of limbic circuits and attentional control. Research findings from several randomized controlled trials suggest that MBCT is a useful intervention for relapse prevention in patients with recurrent depression, with efficacy that may be similar to maintenance antidepressants. Preliminary studies indicate MBCT also shows promise in the treatment of active depression, including treatment-resistant depression. Pilot studies have also evaluated MBCT in bipolar disorder and anxiety disorders. Patient and clinician resources for further information on mindfulness and MBCT are provided.

Functional impairment, stress, and psychosocial intervention in bipolar disorder

The longitudinal course of bipolar disorder (BD) is highly impairing. This article reviews recent research on functional impairment in the course of BD, the roles of social and intrafamilial stress in relapse and recovery, and the role of adjunctive psychosocial interventions in reducing risk and enhancing functioning. Comparative findings in adult and childhood BD are highlighted. Life events and family-expressed emotion have emerged as significant predictors of the course of BD. Studies of social information processing suggest that impairments in the recognition of facial emotions may characterize both adult- and early-onset bipolar patients. Newly developed psychosocial interventions, particularly those that focus on family and social relationships, are associated with more rapid recovery from episodes and better psychosocial functioning. Family-based psychoeducational approaches are promising as early interventions for children with BD or children at risk of developing the disorder. For adults, interpersonal therapy, mindfulness-based strategies, and cognitive remediation may offer promise in enhancing functioning.

Mindfulness-based cognitive therapy for bipolar disorder: effects on cognitive functioning

Bipolar disorder is associated with impairments in cognition, including difficulties in executive functioning, even when patients are euthymic (neither depressed nor manic). The purpose of this study was to assess changes in self-reported cognitive functioning in patients with bipolar disorder who participated in an open pilot trial of mindfulness-based cognitive therapy (MBCT). Following MBCT, patients reported significant improvements in executive functioning, memory, and ability to initiate and complete tasks, as measured by the Behavior Rating Inventory of Executive Function (BRIEF) and the Frontal Systems Behavior Scale (FrSBe). Changes in cognitive functioning were correlated with increases in mindful, nonjudgmental observance and awareness of thoughts, feelings, and sensations, and were not associated with decreases in depression. Improvements tended to diminish after termination of treatment, but some improvements, particularly those in executive functioning, persisted after 3 months. These results provide preliminary evidence that MBCT may be a treatment option that can be used as an adjunct to medication to improve cognitive functioning in bipolar disorder.

Psychotherapies for comorbid anxiety in bipolar spectrum disorders

BACKGROUND

Comorbid anxiety disorders are highly prevalent in bipolar disorder and have been shown to have serious negative impacts on the course of illness. The pharmacological treatment of anxiety can interact with the bipolar disorder and has not been proven effective. As such, many have recommended the psychological treatment of anxiety. This paper reviews the literature on psychological treatments for anxiety comorbid to bipolar disorder.

METHOD

The Medline, PsychInfo and Web of Science databases were thoroughly examined for relevant treatment studies.

RESULTS

Despite frequent recommendations in the literature, surprisingly few have studied the psychological treatment of comorbid anxiety in bipolar disorders. Nevertheless, preliminary results suggest that comorbid anxiety disorders can be effectively treated in a bipolar clientele using cognitive-behavioral therapy, mindfulness-based cognitive-behavioral therapy or relaxation training. In contrast, interpersonal, family therapy and psychoeducation alone would not seem to be beneficial treatment alternatives for anxiety. Cognitive-behavioral therapy appears to reduce the symptoms of obsessive-compulsive disorder, generalized anxiety disorder, panic disorder, post-traumatic stress disorder and general symptoms of anxiety among patients with bipolar disorder. However, the long-term maintenance of anxiety treatment effects may be somewhat reduced and adaptations may be called for to augment and sustain benefits.

CONCLUSIONS

There is an urgent need for randomized controlled trials of different forms of psychotherapy for anxiety disorders comorbid to bipolar disorder. Until such trials are available, the most promising approach would appear to be the sequential or modular CBT-based treatment of the anxiety disorder.

Effects of mindfulness on psychological health: a review of empirical studies

Within the past few decades, there has been a surge of interest in the investigation of mindfulness as a psychological construct and as a form of clinical intervention. This article reviews the empirical literature on the effects of mindfulness on psychological health. We begin with a discussion of the construct of mindfulness, differences between Buddhist and Western psychological conceptualizations of mindfulness, and how mindfulness has been integrated into Western medicine and psychology, before reviewing three areas of empirical research: cross-sectional, correlational research on the associations between mindfulness and various indicators of psychological health; intervention research on the effects of mindfulness-oriented interventions on psychological health; and laboratory-based, experimental research on the immediate effects of mindfulness inductions on emotional and behavioral functioning. We conclude that mindfulness brings about various positive psychological effects, including increased subjective well-being, reduced psychological symptoms and emotional reactivity, and improved behavioral regulation. The review ends with a discussion on mechanisms of change of mindfulness interventions and suggested directions for future research.

Mindfulness based cognitive therapy for psychiatric disorders: a systematic review and meta-analysis

Mindfulness- based Cognitive Therapy (MBCT) is a meditation program based on an integration of Cognitive behavioural therapy and Mindfulness-based stress reduction. The aim of the present work is to review and conduct a meta-analysis of the current findings about the efficacy of MBCT for psychiatric patients. A literature search was undertaken using five electronic databases and references of retrieved articles. Main findings included the following: 1) MBCT in adjunct to usual care was significantly better than usual care alone for reducing major depression (MD) relapses in patients with three or more prior depressive episodes (4 studies), 2) MBCT plus gradual discontinuation of maintenance ADs was associated to similar relapse rates at 1year as compared with continuation of maintenance antidepressants (1 study), 3) the augmentation of MBCT could be useful for reducing residual depressive symptoms in patients with MD (2 studies) and for reducing anxiety symptoms in patients with bipolar disorder in remission (1 study) and in patients with some anxiety disorders (2 studies). However, several methodological shortcomings including small sample sizes, non-randomized design of some studies and the absence of studies comparing MBCT to control groups designed to distinguish specific from non-specific effects of such practice underscore the necessity for further research.

The effect of mindfulness-based cognitive therapy for prevention of relapse in recurrent major depressive disorder: a systematic review and meta-analysis

BACKGROUND

Mindfulness-based cognitive therapy (MBCT) is a group-based clinical intervention program designed to reduce relapse or recurrence of major depressive disorder (MDD) by means of systematic training in mindfulness meditation combined with cognitive-behavioral methods.

OBJECTIVE

By means of a meta-analysis to evaluate the effect of MBCT for prevention of relapse or recurrence among patients with recurrent MDD in remission.

METHOD

Electronic databases were searched and researchers were contacted for further relevant studies. Studies were coded for quality. Meta-analyses were performed by means of the Cochrane Collaboration Review Manager 5.1.

RESULTS

Six randomized controlled trials with a total of 593 participants were included in the meta-analysis. MBCT significantly reduced the risk of relapse/recurrence with a risk ratio of 0.66 for MBCT compared to treatment as usual or placebo controls, corresponding to a relative risk reduction of 34%. In a pre-planned subgroup analysis the relative risk reduction was 43% for participants with three or more previous episodes, while no risk reduction was found for participants with only two episodes. In two studies, MBCT was at least as effective as maintenance antidepressant medication.

CONCLUSION

Results of this meta-analysis indicate that MBCT is an effective intervention for relapse prevention in patients with recurrent MDD in remission, at least in case of three or more previous MDD episodes.

Mindfulness-based cognitive therapy for nonremitted patients with bipolar disorder

INTRODUCTION

Bipolar disorder is characterized by recurrent episodes of depression and/or mania along with interepisodic mood symptoms that interfere with psychosocial functioning. Despite periods of symptomatic recovery, many individuals with bipolar disorder continue to experience substantial residual mood symptoms that often lead to the recurrence of mood episodes.

AIMS

This study explored whether a new mindfulness-based cognitive therapy (MBCT) for bipolar disorder would increase mindfulness, reduce residual mood symptoms, and increase emotion-regulation abilities, psychological well-being, positive affect, and psychosocial functioning. Following a baseline clinical assessment, 12 individuals with DSM-IV bipolar disorder were treated with 12 group sessions of MBCT.

RESULTS

At the end of treatment, as well as at the 3 months follow-up, participants showed increased mindfulness, lower residual depressive mood symptoms, less attentional difficulties, and increased emotion-regulation abilities, psychological well-being, positive affect, and psychosocial functioning.

CONCLUSIONS

These findings suggest that treating residual mood symptoms with MBCT may be another avenue to improving mood, emotion regulation, well-being, and functioning in individuals with bipolar disorder.

Mindfulness-based cognitive therapy for bipolar disorder: a feasibility trial

BACKGROUND

The present open study investigates the feasibility of Mindfulness-based cognitive therapy (MBCT) in groups solely composed of bipolar patients of various subtypes. MBCT has been mostly evaluated with remitted unipolar depressed patients and little is known about this treatment in bipolar disorder.

METHODS

Bipolar outpatients (type I, II and NOS) were included and evaluated for depressive and hypomanic symptoms, as well as mindfulness skills before and after MBCT. Patients' expectations before the program, perceived benefit after completion and frequency of mindfulness practice were also recorded.

RESULTS

Of 23 included patients, 15 attended at least four MBCT sessions. Most participants reported having durably, moderately to very much benefited from the program, although mindfulness practice decreased over time. Whereas no significant increase of mindfulness skills was detected during the trial, change of mindfulness skills was significantly associated with change of depressive symptoms between pre- and post-MBCT assessments.

CONCLUSIONS

MBCT is feasible and well perceived among bipolar patients. Larger and randomized controlled studies are required to further evaluate its efficacy, in particular regarding depressive and (hypo)manic relapse prevention. The mediating role of mindfulness on clinical outcome needs further examination and efforts should be provided to enhance the persistence of meditation practice with time.

Newer variations of cognitive-behavioral therapy: behavioral activation and mindfulness-based cognitive therapy

Recent innovations in the treatment and prevention of depression that build on the foundation of cognitive-behavioral therapy represent promising directions for clinical practice and research. Specifically, behavioral activation and mindfulness-based cognitive therapy have been a recent focus of attention. Behavioral activation is a brief, structured approach to treating acute depression that seeks to alleviate depression by promoting an individual's contact with sources of reward through increasing activation, improving problem solving, and decreasing avoidance and other barriers to activation. Mindfulness-based cognitive therapy is a brief group intervention that seeks to prevent depressive relapse by promoting mindful attention, acceptance, and skillful action to help individuals interrupt habitual cognitive and affective patterns associated with risk of relapse. Each approach is supported by at least two large-scale, randomized clinical trials; however, many important questions remain. We examine current research on both approaches by addressing the robustness of findings, the extension to novel populations, and the processes by which clinical benefit is achieved.
