Mindfulness-based stress reduction intervention for elementary school teachers: a mixed method study.

BACKGROUND: In the Netherlands, more than half of the teachers working in primary education experience high levels of work stress. Compared to other professions, teachers are more likely to drop out from work and develop mental illnesses. Almost one in five even choose a new profession within 5 years after starting as a teacher. This indicates an urgent need for interventions to reduce stress levels in teachers. However, few evidence-based effective interventions targeting stress and work-related problems in the primary educational system are available. AIM: In the current paper, we describe the protocol for a randomized controlled study (RCT) comparing an 8-week mindfulness-based stress reduction (MBSR) intervention with a wait list control condition in primary school teachers. We hypothesize that teachers who participate in the MBSR programme will report less stress (primary outcome) than those in the control group at post-test and at 3-month follow-up. We also expect a decrease in teachers' absenteeism and improvements of mental health, teacher skills, classroom climate quality and the pupil-teacher relationship (secondary outcomes). Finally, we hypothesize that self-compassion, mindfulness skills and emotion regulation skills could mediate effects. METHODS/DESIGN: A mixed-method study will be conducted among N=155 Dutch primary school teachers (grade 1 to 6). The quantitative study will be an RCT, in which teachers will be randomly allocated to the MBSR or waiting list control condition. Trial participants will not be made actively aware of their condition. The data analysts will be blinded. Online questionnaires will be sent to teachers before and after the MBSR programme, and at 3-month follow-up. Information about absenteeism will be collected. In the qualitative part of the study, we will interview teachers to examine their perceived effects of MBSR on their teaching skills, the classroom climate quality and the pupil-teacher relationship. DISCUSSION: This protocol paper describes a mixed-method study design with an RCT and a qualitative evaluation to evaluate an MBSR programme on perceived stress among primary school teachers. If the MBSR programme proves to be effective, it could be implemented as a programme to reduce stress and improve mental health and teaching outcomes in primary school teachers.

Interplay between self-compassion and affect during Mindfulness-Based Compassionate Living for recurrent depression: An Autoregressive Latent Trajectory analysis.

BACKGROUND: The current study aimed to investigate the possible interplay between self-compassion and affect during Mindfulness-Based Compassionate Living (MBCL) in recurrently depressed individuals. METHODS: Data was used from a subsample of a parallel-group randomized controlled trial investigating the efficacy of MBCL in recurrently depressed adults (n = 104). Self-reports of self-compassion and positive/negative affect were obtained at the start of each of the eight MBCL sessions. RESULTS: Bivariate Autoregressive Latent Trajectory (ALT) modeling showed that, when looking at the interplay between self-compassion and positive/negative affect on a session-to-session basis, no significant reciprocal cross-lagged effects between self-compassion and positive affect were found. Although there were no cross-lagged effects from negative affect to self-compassion, higher levels of self-compassion at each session did predict lower levels of negative affect at the subsequent session (bSC(t-1),NA(t) = -0.182, s.e. = 0.076, p = .017). CONCLUSIONS: The current study shows that increases in self-compassion are followed by decreases in negative affect in MBCL for depression.

[RCT about mindfulness-based cognitive therapy for psychological distress in cancer patients]. / RCT naar mindfulness-based cognitieve therapie voor psychische klachten bij oncologische patiënten.

BACKGROUND: Cancer patients may experience psychological distress, like anxiety and depressive symptoms. Mindfulness-based cognitive therapy (MBCT) has been shown to alleviate this psychological distress. However, patients experience barriers in participating in face-to-face MBCT. Individual internet-based MBCT (eMBCT) could be an alternative.
AIM: To compare MBCT and eMBCT to treatment as usual (TAU) for psychological distress in cancer patients.
METHOD: 245 cancer patients with psychological distress were randomly allocated to MBCT (n = 77), eMBCT (n = 90) or TAU (n = 78). Patients completed baseline (T0) and post-intervention (T1) assessments. The primary outcome was psychological distress on the Hospital Anxiety and Depression Scale. Outcomes were analyzed using linear mixed modeling on the intention-to-treat sample. Since both interventions were compared to TAU, the type I error rate was set to p < 0.025.
RESULTS: Compared to TAU, patients reported significantly less psychological distress after both MBCT (Cohen's d = 0.43, p < 0.001) and eMBCT (Cohen's d = 0.63, p < 0.001).
CONCLUSION: Compared to TAU, MBCT and eMBCT were similarly effective in reducing psychological distress in a sample of distressed heterogeneous cancer patients.

Exploring the clinical outcome of Mindfulness-Based Cognitive Therapy for bipolar and unipolar depressive patients in routine clinical practice: a pilot study.

BACKGROUND: Mindfulness Based Cognitive Therapy (MBCT) has been adopted as an evidence-based treatment for unipolar depressive disorder (UDD). Although MBCT has not been included in the treatment guidelines for bipolar disorder (BD), MBCT is regularly being offered to patients with BD in routine clinical practice. In this pilot study we used routine outcome monitoring (ROM) data to explore whether there are indications that patients with BD might benefit less from MBCT than patients with UDD in terms of feasibility and effectiveness. METHODS: The study population consisted of patients with BD (n = 30) or UDD (n = 501) who received MBCT at the Radboudumc Centre for Mindfulness in Nijmegen, the Netherlands. Patients completed self-report measures of depressive symptom severity, worry, well-being, mindfulness skills and self-compassion pre- and post MBCT as part of the ROM. RESULTS: There were significant less patients with BD who decided to start MBCT after intake than patients with UDD. No differences in dropout between groups were found. Results showed significant moderate to large improvements in both groups after MBCT, while no differences between groups were found, on all outcome measures. CONCLUSIONS: This study demonstrates that there are no indications that MBCT, when delivered in heterogeneous patient groups in routine clinical practice, is less beneficial for patients with BD than patients with UDD in terms of feasibility and effectiveness. This lends support to conduct an adequately powered RCT to examine the (cost-)effectiveness of MBCT in BD as the next step before implementing MBCT on a larger scale in patients with BD.

Study protocol of a multicenter randomized controlled trial of mindfulness-based cognitive therapy and treatment as usual in bipolar disorder.

BACKGROUND: Despite multiple pharmacological interventions, many people with bipolar disorder (BD) experience substantial residual mood symptoms, even in the absence of severe mood episodes, which have a negative impact on the course of illness and quality of life. Limited data are available on how to optimize treatment for BD, especially for those who suffer from persistent and residual depressive symptoms. Preliminary evidence suggests Mindfulness-Based Cognitive Therapy (MBCT) as a psychological treatment option for BD. This study aims to investigate whether adding MBCT to treatment as usual (TAU) will result in symptomatic and functional improvements in adults with BD compared to TAU alone. METHODS/DESIGN: This study is a prospective, evaluator blinded, multicenter, randomized controlled trial of MBCT + TAU and TAU alone in 160 adults with bipolar type I and type II. Assessments will be conducted at baseline (T0), mid-treatment (Tmid), and at 3 (T1), 6 (T2), 9 (T3), 12 (T4), and 15 (T5) months follow-up. Primary outcome is post-treatment severity of depressive symptoms (Inventory of Depressive Symptomatology- Clinician administered). Secondary outcomes are severity of (hypo) manic symptoms, anxiety, relapse rates, overall functioning, positive mental health, and cost-effectiveness. As possible mediators will be assessed rumination of negative affect, dampening and rumination of positive affect, mindfulness skills, and self-compassion. DISCUSSION: This study will provide valuable insight into the (cost-)effectiveness of MBCT on clinician- and self-rated symptoms of BD, relapse rates, positive mental health, and overall functioning.

Consolidation and prediction of long-term treatment effect of group and online mindfulness-based cognitive therapy for distressed cancer patients.

BACKGROUND: Group face-to-face and individual internet-based mindfulness-based cognitive therapy (MBCT and eMBCT) have been demonstrated to reduce psychological distress for distressed cancer patients in a randomized controlled trial (RCT). This study focused on the long-term effects of this RCT during the nine-month follow-up period, and on possible predictors, moderators and working mechanisms. METHODS: Distressed cancer patients (n = 245) were randomized to MBCT or eMBCT. Data were collected at baseline, post-treatment, three- and nine-month follow-up. Data were analyzed with linear mixed effect models and (hierarchical) linear regressions. RESULTS: Analyses revealed long-term reductions in psychological distress and rumination, and long-term increases in positive mental health and mental health-related quality of life (QoL) in both interventions over the course of the nine-month follow-up. Interestingly, patients reported less psychological distress in the follow-up period after eMBCT in comparison to MBCT. Less psychological distress, rumination and neuroticism, and more extraversion and agreeableness at baseline predicted less psychological distress at the nine-month follow-up after both interventions. Less mindful and conscientious patients at baseline benefited more from eMBCT than from MBCT. Regarding working mechanisms, changes in mindfulness skills, fear of cancer recurrence and rumination during both interventions predicted less psychological distress at follow-up. CONCLUSIONS: Our findings suggest most improvements in cancer patients' increase over time after both interventions. Furthermore, patients seemed to benefit more from eMBCT than MBCT based on psychological distress levels, especially those patients with low levels of mindfulness skills and conscientiousness.

Exploring associations between psychiatric disorder, psychological distress, and health care utilization in cancer patients.

OBJECTIVE: The mental burden of cancer might elicit additional health care utilization. However, it is unclear how psychiatric disorder and psychological distress relate to health care utilization. Therefore, this study explores associations between psychiatric disorder, psychological distress, and health care utilization. It was hypothesized that presence of psychiatric disorder and psychological distress was associated with increased health care utilization and costs. METHODS: The current study consisted of secondary analyses of baseline data of a larger randomized controlled trial. Two hundred forty-five mixed-cancer patients with at least mild symptoms of psychological distress (Hospital Anxiety and Depression Scale-T ≥ 11) were mainly recruited via online media, participating centers and patient associations. Patients were assessed with Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID-I) for depressive, anxiety, and/or adjustment disorder. Psychological distress was measured by the Hospital Anxiety and Depression Scale. Retrospective self-reported health care utilization in the past 3 months was collected. Associations between predictors and health care utilization in terms of incidence rate ratios (IRR) and costs per category (mental, primary, somatic, and complementary) were assessed by negative binomial, logistic, and gamma regression. RESULTS: Eighty-nine (36.3%) patients suffered from psychiatric disorder, which was associated with mental health care utilization (IRR = 1.63) and costs (OR = 3.11). We observed a nonsignificant trend of somatic health care utilization in patients with psychiatric disorder. Psychological distress was associated with mental health care utilization (IRR = 1.09) and costs (OR = 1.09). Psychological distress was also associated with complementary health care utilization (IRR = 1.03). CONCLUSION: Psychiatric disorder and psychological distress were associated with mental health care use and costs. Psychological distress was associated with complementary health care use. Adequate assessment and referral to mental health care might prevent unnecessary health care utilization.

Cognitive reactivity as outcome and working mechanism of mindfulness-based cognitive therapy for recurrently depressed patients in remission.

Major depressive disorder is a prevalent condition with high relapse rates. There is evidence that cognitive reactivity is an important vulnerability factor for the recurrence of depression. Mindfulness-based interventions are designed to reduce relapse rates, with cognitive reactivity as one of the proposed working mechanisms. In a randomised controlled trial we compared the effect of mindfulness-based cognitive therapy (MBCT) with treatment-as-usual (TAU) on cognitive reactivity in recurrently depressed patients (N = 115). Depressive symptoms, cognitive reactivity, and mindfulness skills were assessed pre and post treatment. Patients in the MBCT group reported a significantly greater reduction in cognitive reactivity than those in the TAU group (d = .51). The reduction of cognitive reactivity appeared to mediate the association between MBCT/TAU and decrease of depressive symptoms, using pre and post scores. The current study provides evidence that MBCT reduces cognitive reactivity and preliminary evidence that cognitive reactivity is a working mechanism of MBCT.

Mindfulness-based stress reduction added to care as usual for lung cancer patients and/or their partners: A multicentre randomized controlled trial.

OBJECTIVE: Lung cancer patients report among the highest distress rates of all cancer patients. Partners report similar distress rates. The present study examined the effectiveness of additional mindfulness-based stress reduction (care as usual [CAU] + MBSR) versus solely CAU to reduce psychological distress in lung cancer patients and/or their partners. METHODS: We performed a multicentre, parallel-group, randomized controlled trial. Mindfulness-based stress reduction is an 8-week group-based intervention, including mindfulness practice and teachings on stress. Care as usual included anticancer treatment, medical consultations, and supportive care. The primary outcome was psychological distress. Secondary outcomes included quality of life, caregiver burden, relationship satisfaction, mindfulness skills, self-compassion, rumination, and posttraumatic stress symptoms. Outcomes were assessed at baseline, post-intervention, and 3-month follow-up. Linear mixed modeling was conducted on an intention-to-treat sample. Moderation (gender, disease stage, baseline distress, participation with/without partner) and mediation analyses were performed. RESULTS: A total of 31 patients and 21 partners were randomized to CAU + MBSR and 32 patients and 23 partners to CAU. After CAU + MBSR patients reported significantly less psychological distress (p = .008, d = .69) than after CAU. Baseline distress moderated outcome: those with more distress benefitted most from MBSR. Additionally, after CAU + MBSR patients showed more improvements in quality of life, mindfulness skills, self-compassion, and rumination than after CAU. In partners, no differences were found between groups. CONCLUSION: Our findings suggest that psychological distress in lung cancer patients can be effectively treated with MBSR. No effect was found in partners, possibly because they were more focused on patients' well-being rather than their own.

Study protocol of a multicenter randomized controlled trial comparing the effectiveness of group and individual internet-based Mindfulness-Based Cognitive Therapy with treatment as usual in reducing psychological distress in cancer patients: the BeMind study.

BACKGROUND: Mindfulness-based interventions have shown to reduce psychological distress in cancer patients. The accessibility of mindfulness-based interventions for cancer patients could be further improved by providing mindfulness using an individual internet-based format. The aim of this study is to test the effectiveness of a Mindfulness-Based Cognitive Therapy (MBCT) group intervention for cancer patients in comparison with individual internet-based MBCT and treatment as usual (TAU). METHODS/DESIGN: A three-armed multicenter randomized controlled trial comparing group-based MBCT to individual internet-based MBCT and TAU in cancer patients who suffer from at least mild psychological distress (Hospital Anxiety and Depression Scale (HADS) ≥ 11). Measurements will be conducted prior to randomization (baseline), post-treatment and at 3 months and 9 months post-treatment. Participants initially allocated to TAU are subsequently randomized to either group- or individual internet-based MBCT and will receive a second baseline measurement after 3 months. Thus, the three-armed comparison will have a time span of approximately 3 months. The two-armed intervention comparison includes a 9-month follow-up and will also consist of participants randomized to the intervention after TAU. Primary outcome will be post-treatment psychological distress (HADS). Secondary outcomes are fear of cancer recurrence (Fear of Cancer Recurrence Inventory), rumination (Rumination and Reflection Questionnaire), positive mental health (Mental Health Continuum - Short Form), and cost-effectiveness (health-related quality of life (EuroQol -5D and Short Form-12) and health care usage (Trimbos and iMTA questionnaire on Costs associated with Psychiatric illness). Potential predictors: DSM-IV-TR mood/anxiety disorders (SCID-I) and neuroticism (NEO-Five Factor Inventory) will be measured. Mediators of treatment effect: mindfulness skills, (Five-Facets of Mindfulness Questionnaire- Short Form), working alliance (Working Alliance Inventory) and group cohesion (Group Cohesion Questionnaire) will also be measured. DISCUSSION: This trial will provide valuable information on the clinical and cost-effectiveness of group versus internet-based MBCT versus TAU for distressed cancer patients.

A brief cognitive-behavioral intervention for treating depression and panic disorder in patients with noncardiac chest pain: a 24-week randomized controlled trial.

BACKGROUND: Most patients with noncardiac chest pain experience anxiety and depressive symptoms. Commonly they are reassured and referred back to primary care, leaving them undiagnosed and untreated. Some small studies have suggested efficacy of 12 cognitive behavioral therapy (CBT) sessions. Our aim was to examine efficacy of brief CBT in reducing anxiety and depressive symptoms in patients with noncardiac chest pain and comorbid panic and/or depressive disorders. METHODS: In this 24-week randomized controlled trial comparing CBT (n = 60) versus treatment as usual (TAU, n = 53), we included all adults who presented at the cardiac emergency unit of a university hospital with noncardiac chest pain, scored ≥8 on the hospital anxiety and depression scale (HADS) and were diagnosed with a comorbid panic and/or depressive disorder with the Mini International Neuropsychiatric Interview. CBT consisted of six individual sessions. Main outcome was disease severity assessed with the clinical global inventory (CGI) by a blinded independent rater. RESULTS: ANCOVA in the intention-to-treat and completer sample showed that CBT was superior to TAU after 24 weeks in reducing disease severity assessed with CGI (P < .001). Secondary outcomes on anxiety (HADS-anxiety, state trait anxiety inventory (STAI)-trait) and depressive symptoms (Hamilton depression rating scale) were in line with these results except for HADS-depression (P = .10), fear questionnaire (P = .13), and STAI-state (P = .11). CONCLUSIONS: Brief CBT significantly reduces anxiety and depressive symptoms in patients with noncardiac chest pain who are diagnosed with panic and/or depressive disorders. Patients presenting with noncardiac chest pain should be screened for psychopathology and if positive, CBT should be considered.

The cardiac anxiety questionnaire: cross-validation among cardiac inpatients.

OBJECTIVE: General anxiety symptoms are common in patients with cardiac disease and considered to have an adverse effect on cardiac prognosis. The role of specific cardiac anxiety, however, is still unknown. The aim of this study is to examine the factor structure, reliability, and validity of the Dutch version of the Cardiac Anxiety Questionnaire (CAQ), which was specifically designed to assess heart focused anxiety. METHODS: Two hundred thirty-seven patients admitted for an acute coronary syndrome (ACS) and a control group of 49 patients admitted for an exacerbation of rheumatoid arthritis (RA) completed the CAQ, the Agoraphobic Cognitions Questionnaire, Mobility Inventory, Beck Depression Inventory, Beck Anxiety Inventory, and the State-Trait Anxiety Inventory. RESULTS: Although the original three-factor solution (fear, avoidance, and attention) was acceptable (model fit parameters: CFI = 0.89 and TLI = 0.87), our data were best explained by a four-factor model including safety seeking behaviors. Internal consistency and test-retest reliability were good. The CAQ had moderate correlations with the other anxiety and depression questionnaires. Recently admitted ACS patients had significantly higher scores than RA patients, even after controlling for general anxiety and depressive symptoms (p < 0.001). CONCLUSION: The CAQ is a reliable and valid instrument to assess cardiac anxiety in patients hospitalized with ACS. These results enable longitudinal studies to examine the relationship of heart-focused anxiety with cardiac prognosis and to evaluate interventions specifically targeted at anxiety in cardiac patients.

One-year follow up of cardiac anxiety after a myocardial infarction: a latent class analysis.

INTRODUCTION: Longitudinal elevated depressive symptom scores are associated with a less favorable cardiac outcome. Although anxiety has received less attention, meta-analysis suggests that high baseline levels of general anxiety might worsen cardiac outcome. The objective of this study was to explore the longitudinal course of cardiac anxiety after a myocardial infarction (MI). METHODS: The Cardiac Anxiety Questionnaire (CAQ) was administered to 194 patients hospitalized for MI after admission, and one, three, six and twelve months after discharge. Latent class growth analysis (LCGA) was performed to identify groups based on cardiac anxiety course. Between group differences were checked on relevant socio-demographic, cardiac and psychiatric variables. RESULTS: LCGA identified three groups with stable CAQ levels over time, indicative of high (7.7%), intermediate (45.4%) and low (30.4%) levels of cardiac anxiety, respectively. A fourth group (16.5%) reported high levels of cardiac anxiety that decreased over time. Between group differences were of particular interest for the two subgroups that started high in cardiac anxiety, since these may differentiate patients with spontaneous remission from those who might be in need of treatment. Patients in whom cardiac anxiety persisted were less often employed, had more diabetes mellitus, a history of acute coronary syndrome, depressive symptoms, anxiety and avoidance at baseline and a lower quality of life at follow-up. CONCLUSION: This first study addressing cardiac anxiety after an MI identified four trajectories. Future studies should focus on cardiac outcome and treatment strategies for cardiac anxiety in the subgroup with persistent high anxiety levels.

The efficacy of mindfulness-based cognitive therapy in recurrent depressed patients with and without a current depressive episode: a randomized controlled trial.

BACKGROUND: The aim of this study is to examine the efficacy of mindfulness-based cognitive therapy (MBCT) in addition to treatment as usual (TAU) for recurrent depressive patients with and without a current depressive episode. METHOD: A randomized, controlled trial comparing MBCT+TAU (n=102) with TAU alone (n=103). The study population consisted of patients with three or more previous depressive episodes. Primary outcome measure was post-treatment depressive symptoms according to the Hamilton Rating Scale for Depression. Secondary outcome measures included the Beck Depression Inventory, rumination, worry and mindfulness skills. Group comparisons were carried out with linear mixed modelling, controlling for intra-group correlations. Additional mediation analyses were performed. Comparisons were made between patients with and without a current depressive episode. RESULTS: Patients in the MBCT+TAU group reported less depressive symptoms, worry and rumination and increased levels of mindfulness skills compared with patients receiving TAU alone. MBCT resulted in a comparable reduction of depressive symptoms for patients with and without a current depressive episode. Additional analyses suggest that the reduction of depressive symptoms was mediated by decreased levels of rumination and worry. CONCLUSIONS: The study findings suggest that MBCT is as effective for patients with recurrent depression who are currently depressed as for patients who are in remission. Directions towards a better understanding of the mechanisms of action of MBCT are given, although future research is needed to support these hypotheses.

Medically unexplained physical symptoms: the feasibility of group cognitive-behavioural therapy in primary care.

OBJECTIVE: The aim of this study was to estimate the number of patients with medically unexplained physical symptoms (MUPS) that could be eligible for group cognitive-behavioural treatment (CBT) and to assess the acceptability of this treatment. METHODS: For 3 months, all consultations of one general practitioner (GP) were screened for MUPS. Patients with MUPS who were considered eligible for group CBT were interviewed and offered treatment. RESULTS: From January to March 1999, 1084 consultations of 796 patients were screened. The GP classified the symptoms of 104 patients aged 25-79 as unexplained. Of these, 71 patients were not considered to be eligible for treatment, mainly due to a psychological attribution of the symptoms. The research interview was offered to 33 patients, 16 of them declined and 12 were interviewed. Seven out of the 12 eligible patients accepted treatment. CONCLUSION: In primary care, 18% of patients aged 25-79 years was estimated to have MUPS. For only a minority of these patients, group CBT was considered suitable and acceptable.
