Mindfulness-Based Treatment for People With Severe Mental Illness: A Literature Review

How do mindfulness-based interventions promote coping and self-efficacy in patients with cancer: A systematic review of qualitative and quantitative data

OBJECTIVE

The purpose of this study was to review the existing quantitative and qualitative evidence regarding how mindfulness-based interventions (MBIs) help cope with cancer-related challenges and increase affected patients' perceived self-efficacy.

METHODS

A systematic literature search was conducted on PubMed, PsycInfo, PubPsych, and CINAHL. Quantitative, qualitative, and mixed methods studies were included if they (1) evaluated MBIs (2) for patients with cancer or cancer survivors (3) regarding their impact on coping with cancer and perceived self-efficacy. The reports were screened by two independent reviewers and conflicts were resolved by a third reviewer. The review was pre-registered on PROSPERO (CRD42022368765).

RESULTS

Findings from 28 reports of 19 quantitative studies, six qualitative studies, and three mixed-methods studies (total N = 1722) were extracted and integrated. The synthesis of quantitative data showed considerable heterogeneity in outcomes and measurement instruments. Most often reported were significant positive impacts of mindfulness on general coping skills, self-regulation, and perceived efficacy in coping with cancer. Qualitative interviews with patients supported those results. The three meta-themes identified were that MBI (1) provided patients with tools to use in stressful situations, (2) promoted a general change of mindset and (3) created a feeling of social connectedness.

CONCLUSIONS

The reviewed studies suggest that MBI can promote coping and enhance the perceived self-efficacy of patients with cancer. In the future, more research investigating the different aspects of coping and the potentially moderating role of self-efficacy could provide further insights with respect to how coping and self-efficacy related to MBI.

Effectiveness of mindfulness-based intervention in schizophrenia: A meta-analysis of randomized controlled trials

Schizophrenia poses significant societal challenges, including interpersonal tension, an increased risk of suicide, and soaring medical costs. Although antipsychotics can prevent relapses, they often give rise to adverse effects and do not provide lasting relief. Mindfulness-based interventions (MBI) emerge as a hopeful avenue for improving outcomes. However, existing research and meta-analyses of the efficacy of MBI in schizophrenia remain limited. This study aimed to evaluate the efficacy of MBI as an adjunctive therapy for schizophrenia. Relevant randomized controlled trials (RCTs) were searched across PubMed, Embase, Web of Science, and Cochrane Library from inception dates up to January 12, 2023. Statistical analyses were conducted using Stata software (version 15.0) and Review Manager 5.4. The quality of the included RCTs was assessed using the revised Cochrane risk of bias tool. A total of 18 RCTs were included, with 675 patients and 704 health controls. Our meta-analysis revealed that MBI significantly improved psychosocial function, insight, and mindfulness in individuals with schizophrenia. The quality of the included RCTs had a low to moderate risk of bias. These findings suggest that MBI holds promise for improving the mental health of individuals with schizophrenia.

Effectiveness of a mindfulness-based intervention for persons with early psychosis: A multi-site randomized controlled trial

BACKGROUND

The Mindfulness Ambassador Program (MAP) is a group-based, facilitated mindfulness-based intervention (MBI). We sought to determine the effectiveness of MAP on reducing negative psychotic symptoms and enhancing mindfulness skills among persons experiencing early psychosis.

METHODS

We conducted a pragmatic randomized controlled trial (RCT) at three early psychosis intervention (EPI) programs in Ontario, Canada. Participants (N = 59) were randomly assigned to receive MAP (n = 29) for 1-hour weekly sessions over 3 months, or to treatment as usual (TAU, n = 30). Assessments were conducted at baseline, 3 months, and 6 months using the Self-Evaluation of Negative Symptoms (SNS) and Kentucky Inventory of Mindfulness Skills (KIMS). Linear mixed methods were used to assess the joint effects of group and time.

RESULTS

At 3 months, participants who received MAP (n = 17) demonstrated greater reductions on the SNS relative to TAU (n = 15), which were clinically and statistically significant (-4.1; 95%CI -7.5, -0.7; p = 0.019). At 6 months, the difference between MAP (n = 10) and TAU (n = 13) was no longer statistically significant (-1.2; 95%CI -5.2,2.7; p = 0.54). On the KIMS, no significant effects were found at 3 months (+0.3; 95%CI -2.0,2.5; p = 0.82) or 6 months (+0.4; 95%CI -2.2,2.9; p = 0.79).

CONCLUSIONS

We conducted one of the first multi-site RCTs of a MBI for early psychosis. Our findings indicated that MAP was more effective in reducing negative symptoms compared to TAU in the short term. Earlier reductions in negative psychotic symptoms may help facilitate recovery in the long term.

Exploring Zentangle as a virtual mindfulness-based art intervention for people with serious mental illness

Introduction

Zentangle is an emerging art intervention that incorporates mindfulness into creative drawing. This pilot study explored Zentangle as a novel adjunct treatment for people with serious mental illness (SMI).

Methods

Six participants with SMI completed an 8-week Zentangle program. Psychiatric outcomes were evaluated using the Brief Psychiatric Rating Scale (BPRS), Mindful Attention Awareness Scale (MAAS), Perceived Stress Scale (PSS), and Quality of Life Enjoyment and Satisfaction Scale (Q-LES-Q-SF). A focus group was conducted to better understand the experiences of the participants.

Results

A significant reduction in psychiatric symptoms was observed as measured by the total score on the BPRS between baseline and 5-week post-intervention (40.7 ± 9.1 vs. 33.7 ± 8.9, mean ± SD, p = 0.02). Participants also showed a significant increase in mindful attention using the average score on the MAAS between 1- and 5-week post-intervention (3.5 ± 0.4 vs. 4.2 ± 0.7, mean ± SD, p = 0.04). Four themes were generated from the focus group: (1) approaching mindfulness through Zentangle; (2) power of uncomplicated art creation; (3) understanding the value of self-appreciation; and (4) fostering a positive environment.

Discussion

Our preliminary data suggest that the use of Zentangle for participants with SMI may have a positive impact on overall psychiatric symptoms and mindfulness. Moreover, the Zentangle Method encourages positive emotions like gratitude and self-accomplishment to counteract negative feelings of self-criticism and failure in participants.

Psychological Inflexibility in People with Chronic Psychosis: The Mediating Role of Self-Stigma and Social Functioning

Psychosis is associated with self-stigmatization and loss of social functioning that increase the severity of the disorder. Psychological inflexibility (PI)—an individual’s tendency to suppress undesirable private events—plays a fundamental role in the emergence and worst prognosis of psychosis. The main objective of this study was to analyze whether self-stigma and social functioning mediate the association of PI with the severity of psychosis in adults with chronic schizophrenia. The study was carried out with a sample of 103 outpatients. The Acceptance and Action Questionnaire, the Internalized Stigma of Mental Illness Scale, and the Social Functioning Scale were used for clinical assessments. Data analyses were performed by using the PROCESS macro for SPSS. Results showed that the link between PI and the severity of psychosis is not direct, but is better explained by mediation of the self-stigma and social functioning of those assessed. PI also predicts worse social functioning without the need to take self-stigma into account. Moreover, self-stigma alone does not predict the severity of psychotic symptoms; this relationship has to be mediated by social functioning. These findings suggest that interventions designed to increase psychological flexibility, such as Acceptance and Commitment Therapy (ACT), may offer an alternative to attenuate the negative impact of self-stigma and to improve the social functioning.

Effects of Mindfulness-Based Cognitive Therapy on Stigma in Female Patients With Schizophrenia

Mindfulness-based cognitive therapy (MBCT) has been increasingly recognized as effective in different mental illnesses, but these effects are limited in schizophrenia. For patients with schizophrenia, stigma is one of the most negative factors that affects treatment, rehabilitation and social function. This research aimed to determine the effects of MBCT on stigma in patients with schizophrenia. In total, 62 inpatients with schizophrenia were recruited and randomly assigned to the experimental group or control group. The experimental group received an 8-week MBCT intervention, and the control group were treated as usual. Link's Stigma Scales (with three subscales, including perceived devaluation-discrimination (PDD), stigma-coping orientation, and stigma-related feeling), Five Facet Mindfulness Questionnaire (FFMQ), and Insight and Treatment Attitudes Questionnaire (ITAQ) were used to collect data before and after intervention. After intervention, the post-test score of PDD, stigma-coping orientation, FFMQ, and ITAQ were significantly different between the experimental group and the control group. In the experimental group, the PDD and stigma-coping orientation scores significantly decreased, and FFMQ and ITAQ scores increased remarkably (P < 0.05). In addition, correlation analysis revealed a significant negative correlation between mindfulness and stigma. MBCT was effective in reducing stigma in patients with schizophrenia, which mainly manifested as changes in the patients' perception of stigma as well as the withdrawal and avoidance caused by schizophrenia. Enhancing mindfulness will help reduce the stigma level. MBCT is worthy of promotion and application in patients with schizophrenia.

The feasibility of mindfulness-based cognitive therapy for people with bipolar disorder: a qualitative study

Background

Mindfulness- Based Cognitive Therapy (MBCT) could be a promising psychosocial intervention for people with bipolar disorder (BD). However, little is known about the feasibility of MBCT for people with BD. In this study we explore the facilitators and barriers people with BD experience of an adapted MBCT program.

Method

This qualitative study is part of a large, multicenter randomized controlled trial on MBCT for BD (trial registration number: NCT03507647). The present study included 16 participants with BD who participated in an 8-week adapted MBCT program. Semi- structured interviews exploring the feasibility, with a particular focus on the bipolar symptoms, were recorded verbatim, transcribed and analyzed. For reasons of triangulation, teachers were interviewed as well.

Results

Participants reported different barriers and facilitators of MBCT, both generally as well as with regard to their bipolar disorder. Four key themes arose: the training itself, psychosocial factors, personal characteristics and the bipolar disorder. Themes were further divided in subthemes.

Conclusion

The adapted MBCT program seemed to be feasible for people with BD. Depressive symptoms often acted as a barrier for participating in MBCT, suggesting that participants might need additional support when depressed. Manic symptoms could act both as a barrier and facilitator, suggesting that the occurrence of (hypo)mania does not necessarily have to be an exclusion criterion for participation. Further clinical and research implications are suggested.

Clinical and psychosocial factors associated with depression in patients with psychosis according to stage of illness

AIM

This study investigated the clinical characteristics and psychosocial factors associated with depression in patients with early psychosis according to stage of illness.

METHODS

The present study includes patients who fulfil the DSM-5 criteria for schizophrenia spectrum and other psychotic disorders. Patients were divided into two groups according to illness stage (the acute stage of first-episode psychosis and stabilization phase of recent-onset psychosis). Clinically meaningful depression was defined as moderate or severe on the depression dimension of the Clinician-Rated Dimensions of Psychosis Symptom Severity scale in the DSM-5.

RESULTS

In total, 340 (207 first-episode and 133 recent-onset) patients were recruited in this study. Patients with comorbid depression were characterized by frequent suicidal ideation, a past suicide attempt, and lower scores on the Subjective Well-being Under Neuroleptics and Brief Resilience Scale in both groups. Long duration of untreated psychosis and higher scores on the Early Trauma Inventory Self Report were associated with depression in the acute stage of first-episode psychosis. In the stabilization phase of recent-onset psychosis group, a monthly income and scores for sexual desire and on the Family Adaptability and Cohesion Evaluation Scale-III were significantly lower in patients with depression than in those without depression.

CONCLUSION

Comorbid depression was associated with high suicidality, lower quality of life and poor resilience in patients with first-episode and recent-onset psychosis. Depression was associated with factors that had been present before the initiation of treatment in patients with first-episode psychosis and with environmental factors in those in the stabilization phase.

Meditation techniques v. relaxation therapies when treating anxiety: a meta-analytic review

To what extent meditation techniques (which incorporate practices to regulate attention, construct individual values, or deconstruct self-related assumptions), are more or less effective than relaxation therapy in the treatment of anxiety, is not clear. The aim of this study was to examine the effectiveness of meditation compared to relaxation in reducing anxiety. A systematic review from PubMed, Embase, PsycInfo and the Cochrane Central was conducted. A meta-analysis of 14 RCTs (n = 862 participants suffering from anxiety disorders or high trait anxiety) was performed. Effect sizes (ESs) were determined by Hedges' g. Heterogeneity, risk of publication bias, quality of studies/interventions, and researcher allegiance, were evaluated. Meditation techniques incorporated attentional elements, and five of them also added constructive practices. No studies were found using deconstructive exercises. The overall ES was g = -0.23 [95% confidence interval (CI) -0.40 to -0.07], favouring meditation (number needed to treat = 7.74). Heterogeneity was low (I2 = 2; 95% CI 0 to 56). There was no evidence of publication bias, but few studies and interventions were of high quality, and allegiance might be moderating results. Meditation seems to be a bit more effective than relaxation in the treatment of anxiety, and it might also remain more effective at 12-month follow-up. However, more research using the full spectrum of meditation practices to treat different anxiety disorders, including independent studies to avoid researcher allegiance, is needed if we are to have a precise idea of the potential of these techniques compared to relaxation therapy.

The effect of a brief mindfulness-based intervention on personal recovery in people with bipolar disorder: a randomized controlled trial (study protocol)

BACKGROUND

With the advent of the recovery movement in mental health, a humanistic paradigm shift has occurred, placing the focus on personal recovery (i.e., hope, identity, and life meaning) instead of functional or clinical recovery only (i.e., symptom reduction or increases in physical function). Along the journey of recovery, people with bipolar disorder (BD) struggle to cope with recurring mood fluctuations between depression and mania. Mindfulness-based interventions (MBIs) have the potential to result in improvements in personal recovery outcomes. Thus, this protocol will evaluate the efficacy and mechanisms of a brief MBI for helping individuals with BD with their personal recovery. It is hypothesized that adults with BD randomly assigned to a brief MBI intervention will report greater improvements in personal recovery than those in a waiting list control condition. In addition, it is hypothesized that such benefits will be mediated by improvements in emotion awareness, emotion regulation, and illness acceptance. Moreover, the specific stage of BD is hypothesized to moderate the beneficial effects of the brief MBI, such that those in the early stage of BD will report more benefits regarding emotion awareness and emotion regulation, whereas those in the late stage of BD will report more advantages concerning illness acceptance.

METHOD

One hundred and fifty-four adults with BD will be recruited from hospitals and community settings for this research project. This study will use a mixed methods design. A randomized-controlled trial will be conducted to compare a brief MBI (four sessions in total) group and a waiting list control group. Assessments will be made at baseline, after intervention, and at six-month follow-up. In addition, a qualitative and participatory research method called Photovoice will be employed to further understand the experiences of the participants who receive the brief MBI along their personal recovery journey.

DISCUSSION

If the study hypotheses are supported, the findings from this research project will provide empirical support for an alternative treatment. Moreover, by identifying the mechanisms of the beneficial effects of the brief MBI, the findings will highlight process variables that could be specifically targeted to make MBI treatment even more effective in this population.

A Brief Mindfulness-Based Family Psychoeducation Intervention for Chinese Young Adults With First Episode Psychosis: A Study Protocol

Family psychoeducation (FPE) has been recommended as a major component in the treatment of psychosis. Many previous studies have implemented an intensive program design that often only emphasized improvements in patients' illness outcomes but the benefits for caregivers were limited. There have been calls for a time-limited but cost-effective FPE program to mitigate the looming reality of the suffering of people with psychosis and their families. A Brief Mindfulness-Based Family Psychoeducation for psychosis program is developed to reduce caregivers' burden and promote young adult's recovery. A randomized controlled trial will be conducted to compare this intervention with an ordinary FPE intervention. Both arms will involve six sessions, with a total contact time of 12 h. 300 caregivers of young adults who have experienced first episode psychosis within last 3 years will be recruited. Program effectiveness will be assessed by comparing outcomes measuring the caregivers' burden, mental health symptoms, positive well-being, and the young adult's mental health symptoms during the study and at 9-month post-randomization. The role of expressed emotions, interpersonal mindfulness, and non-attachment in mediating these outcomes will be explored. An additional qualitative approach Photovoice is selected to explore the complex family experiences and the benefits of mindfulness from the caregivers' personal perspectives. Trial Registration: The trial is registered with the United States Clinical Trials Registry (ClinicalTrials.gov): NCT03688009.

Mindfulness in severe and persistent mental illness: a systematic review

OBJECTIVE

This systematic review summarises the current state of research on mindfulness in SPMI, given the pressing need to provide alternative, scalable and cost-effective treatment modalities for patients with severe and persistent mental illness (SPMI).

METHODS

Articles included mindfulness-based interventions for SPMI. Excluded articles included qualitative studies, acceptance and compassion therapies, case reports and reviews. Studies were identified by searching the databases Medline, Embase and PsycINFO.

RESULTS

Six randomised controlled trials, seven prospective studies and one retrospective study were identified. Clinical improvements were observed on psychotic symptoms, and on improvements of depression symptoms, cognition, mindfulness, psycho-social and vocational factors.

CONCLUSIONS

Findings suggest that mindfulness is feasible for individuals with SPMI, and displays potential benefits in outcomes aside from psychotic symptoms. The effects of mindfulness in psychotic symptoms needs further investigation in larger definitive studies using methodological rigor and thorough assessments of other psychiatric populations who are also representative of SPMI.

Effects of Mindfulness-Based Psychoeducation on the Internalized Stigmatization Level of Patients With Schizophrenia

The aim of this study was to determine the effects of mindfulness-based psychoeducation on internalized stigma in patients with schizophrenia. The patients were recruited from the community mental health centers. This quasiexperimental study was conducted using pretests and posttests with a control group. The participants were 69 patients with schizophrenia; 34 were part of the experimental group and 35 were part of the control group. The patients in the experimental group participated 2 days a week for 6 weeks in a total of 12 sessions which were given in the form of face-to-face group training. The difference between the scale mean posttest scores of the patients in the experimental and control groups was found to be statistically significant (p < .05). In the intragroup comparisons, a significant difference was found between the stigma mean scores in the experimental group (p < .05). It was concluded that mindfulness-based psychoeducation was effective in reducing stigma in patients with schizophrenia.

Web-based intervention to improve quality of life in late stage bipolar disorder (ORBIT): randomised controlled trial protocol

BACKGROUND

The primary objective of this randomised controlled trial (RCT) is to establish the effectiveness of a novel online quality of life (QoL) intervention tailored for people with late stage (≥ 10 episodes) bipolar disorder (BD) compared with psychoeducation. Relative to early stage individuals, this late stage group may not benefit as much from existing psychosocial treatments. The intervention is a guided self-help, mindfulness based intervention (MBI) developed in consultation with consumers, designed specifically for web-based delivery, with email coaching support.

METHODS/DESIGN

This international RCT will involve a comparison of the effectiveness and cost-effectiveness of two 5-week adjunctive online self-management interventions: Mindfulness for Bipolar 2.0 and an active control (Psychoeducation for Bipolar). A total of 300 participants will be recruited primarily via social media channels. Main inclusion criteria are: a diagnosis of BD (confirmed via a phone-administered structured diagnostic interview), no current mood episode, history of 10 or more mood episodes, no current psychotic features or active suicidality, under the care of a medical practitioner. Block randomisation will be used for allocation to the interventions, and participants will retain access to the program for 6 months. Evaluations will be conducted at pre- and post- treatment, and at 3- and 6- months follow-up. The primary outcome measure will be the Brief Quality of Life in Bipolar Disorder Scale (Brief QoL.BD), collected immediately post-intervention at 5 weeks (T1). Secondary measures include BD-related symptoms (mania, depression, anxiety, stress), time to first relapse, functioning, sleep quality, social rhythm stability and resource use. Measurements will be collected online and via telephone assessments at baseline (T0), 5 weeks (T1), three months (T2) and six months (T3). Candidate moderators (diagnosis, anxiety or substance comorbidities, demographics and current treatments) will be investigated as will putative therapeutic mechanisms including mindfulness, emotion regulation and self-compassion. A cost-effectiveness analysis will be conducted. Acceptability and any unwanted events (including adverse treatment reactions) will be documented and explored.

DISCUSSION

This definitive trial will test the effectiveness and cost-effectiveness of a novel QoL focused, mindfulness based, online guided self-help intervention for late stage BD, and investigate its putative mechanisms of therapeutic action.

Unraveling the insight paradox: One-year longitudinal study on the relationships between insight, self-stigma, and life satisfaction among people with schizophrenia spectrum disorders

The promotion of insight among people with schizophrenia spectrum disorders has posed a dilemma to service providers as higher insight has been linked to positive clinical outcomes but negative psychological outcomes. The negative meaning that people attached to the illness (self-stigma content) and the recurrence of such stigmatizing thoughts (self-stigma process) may explain why increased insight is associated with negative outcomes. The present study examined how the presence of high self-stigma content and self-stigma process may contribute to the negative association between insight and life satisfaction. A total of 181 people with schizophrenia spectrum disorders were assessed at baseline. 130 and 110 participants were retained and completed questionnaire at 6-month and 1-year follow-up, respectively. Results showed that baseline insight was associated with lower life satisfaction at 6-month when self-stigma process or self-stigma content was high. Furthermore, baseline insight was predictive of better life satisfaction at 1-year follow-up when self-stigma process was low. Findings suggested that the detrimental effects of insight can be a result from both the presence of cognitive content and habitual process of self-stigma. Future insight promotion interventions should also address self-stigma content and process among people with schizophrenia spectrum disorders so as to maximize the beneficial effects of insight.

Attentional avoidance increases voice hearing in an analogue task in people with psychosis: An experimental study

Cognitive models of psychosis suggest that unhelpful ways of responding to experiences can maintain such experiences and the associated distress. The response styles of attentional avoidance and attentional focusing were manipulated in an analogue voice-hearing task. Predictions were that both would increase detection of words in response to an ambiguous audio-recording but that attentional avoidance would lead to a greater increase than focusing. We also predicted that there would be a greater increase in anxiety and distress in the avoidance group. Predictions were tested in a sample of 44 participants with a diagnosis of schizophrenia. Participants were randomly assigned to either attentional avoidance or focusing while listening to an ambiguous auditory task. Number of words identified and anxiety and distress were recorded. As predicted, there was an increase in the number of words identified in both groups; however, this increase was greater in the avoidance group. The prediction that there would also be an increase in distress that would be greater in the avoidance group was not supported. It is possible that emotional reactions relate more closely to appraisals of the voice. The results suggest that avoidance of experiences is particularly counterproductive and can result in greater detection of experiences.

Mobile Mindfulness Intervention on an Acute Psychiatric Unit: Feasibility and Acceptability Study

BACKGROUND

Aggression and violence on acute psychiatric inpatient units is extensive and leads to negative sequelae for staff and patients. With increasingly acute inpatient milieus due to shorter lengths of stay, inpatient staff is limited in training and time to be able to provide treatments. Mobile technology provides a new platform for offering treatment on such units, but it has not been tested for feasibility or usability in this particular setting.

OBJECTIVE

The aim of this study was to examine the feasibility, usability, and acceptability of a brief mindfulness meditation mobile phone app intended to reduce anger and aggression in acute psychiatric inpatients with schizophrenia, schizoaffective disorder, or bipolar disorder, and a history of violence.

METHODS

Participants were recruited between November 1, 2015 and June 1, 2016. A total of 13 inpatients at an acute care state hospital carried mobile phones for 1 week and were asked to try a commercially available mindfulness app called Headspace. The participants completed a usability questionnaire and engaged in a qualitative interview upon completion of the 7 days. In addition, measures of mindfulness, state and trait anger, and cognitive ability were administered before and after the intervention.

RESULTS

Of the 13 enrolled participants, 10 used the app for the 7 days of the study and completed all measures. Two additional participants used the app for fewer than 7 days and completed all measures. All participants found the app to be engaging and easy to use. Most (10/12, 83%) felt comfortable using Headspace and 83% (10/12) would recommend it to others. All participants made some effort to try the app, with 6 participants (6/12, 50%) completing the first 10 10-minute "foundation" guided meditations.

CONCLUSIONS

This is the first known study of the use of a commercially available app as an intervention on acute psychiatric inpatient units. Acutely ill psychiatric inpatients at a state hospital found the Headspace app easy to use, were able to complete a series of meditations, and felt the app helped with anxiety, sleep, and boredom on the unit. There were no instances of an increase in psychotic symptoms reported and there were no episodes of aggression or violence noted in the record.

Citation patterns and trends of systematic reviews about mindfulness

OBJECTIVES

We performed a citation analysis of the literature about mindfulness aimed at describing the most significant topics and the impact of more relevant papers.

METHODS

We classified 128 systematic reviews about mindfulness-based intervention retrieved in Scopus according to their object, the population included and the type of mindfulness proposed. The citation counting was reported. The cumulative citation numbers per chronological years and article life were analyzed thorough a linear regression model.

RESULTS

1) We observed a general increase in the number of reviews published from 2003 to 2016; 2) two reviews collected the 33% of the overall citations; 3) citation counting for clinical and mixed population collected the 90% of total citations; 4) clinical reviews had higher cumulative citation per publication/year growth.

CONCLUSIONS

As mindfulness research advances, higher attention should be given to the mechanisms by which mindfulness interventions work so as to provide fruitful insights for future research.

Contextual Cognitive-Behavioral Therapies Across the Psychosis Continuum

Abstract. Considering several etiologic, therapeutic, and comorbidity-related factors, a psychosis continuum model has been proposed for the understanding and treatment of psychotic disorders. Within the new emerging treatment approaches, Contextual Cognitive-Behavioral Therapies (CCBT) seem to hold promise for the psychosis continuum. However, considering their novelty for this specific population, the quality of efficacy evidence remains unclear. Objective: To examine, critically analyze, and summarize the results from studies based on therapeutic models within the CCBT approach (Mindfulness and Acceptance-based interventions, Compassion-Focused Therapy, Dialectical Behavior Therapy, and Metacognitive Therapy) for patients with a diagnosis within the psychosis continuum (schizophrenia, schizoaffective disorder, bipolar disorder). Methods: Three leading electronic databases (MEDLINE/PUBMED; PsycINFO; Cochrane Library), a grey literature database (OpenGrey), and registered clinical trials (ClinicalTrials.Gov) were searched using combinations of key terms regarding the CCBT models and the diagnosis considered. Reference lists of the relevant studies and reviews were searched. Only Randomized Controlled Trials (RCTs) were included. The “Cochrane Risk of Bias Assessment Tool” was used for quality assessment. Results: A total of 17 articles were included. This review was based on a majority of unclear or low risk of bias studies. Benefits regarding clinical variables such as psychotic symptoms, anxiety and depression, functioning or quality of life were found. Conclusion: Overall the studies supported some benefits of CCBT approaches for the psychosis continuum. The conceptual perspective on treatment has changed, nevertheless the outcomes assessed are still symptom-focused and there is still need for improvement. Methodological considerations and future directions are presented.

Mindfulness interventions for psychosis: a systematic review of the literature

WHAT IS KNOWN ON THE SUBJECT?: Psychosis and the more specific diagnosis of schizophrenia constitute a major psychiatric disorder which impacts heavily on the self-esteem, functioning and quality of life of those affected. A number of mindfulness therapies have been developed in recent years, showing promising results when used with people with the disorder. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This review of the literature included only randomized controlled trials (RCTs), rather than other typically less robust methods of research (e.g. case studies, noncontrolled studies). WHAT ARE THE IMPLICATIONS FOR PRACTICE?: We concluded that mindfulness therapies can be safely used with people with psychosis and that they provide a number of therapeutic benefits compared with routine care and, in some cases, other interventions. Larger, methodologically improved trials are now recommended to evaluate the benefits of mindfulness therapies further.

ABSTRACT

Introduction A growing number of mindfulness interventions are being used with individuals with psychosis. These therapies employ elements of acceptance and compassion in addition to mindfulness. A number of randomized controlled trials (RCTs) of these interventions have emerged in recent years, but no review of these latest trials exists. Question 'For individuals with psychosis, are mindfulness interventions more effective than treatment as usual or an alternative intervention, in improving patient-related outcomes as demonstrated in RCTs?' Method We undertook a systematic review of randomized controlled studies of mindfulness interventions for psychosis and schizophrenia (MIps). Studies were identified by searching the databases Medline, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, and Allied and Complementary Medicine. Findings The review identified 11 RCTs investigating eight mindfulness interventions. Significant improvements were reported on a number of measures, although gains were mostly smaller in trials employing well-designed controls and where assessors were blind to treatment allocation. There was considerable heterogeneity amongst trials in the diversity of treatments reviewed and the range of outcomes assessed. Implications for Practice The findings suggest MIps are feasible for individuals with psychosis and provide a number of significant benefits over routine care and, in some cases, other interventions.

Resilience, internalized stigma, self-esteem, and hopelessness among people with schizophrenia: Cultural comparison in Austria and Japan

Resilience is becoming an important topic in people with schizophrenia since there is evidence that it increases the probability for long-term recovery. The current study investigated transcultural differences in resilience across schizophrenia patients from two different geographical regions, Austria and Japan. Another objective was to examine transcultural differences in internalized stigma, self-esteem, and hopelessness, which can be expected to be relevant in this context, as well as the interrelations between these subjective elements of recovery and symptom severity. To this end, patients from outpatient mental health services in Innsbruck, Austria (N=52) and Tokyo, Japan (N=60) as well as 137 healthy comparison subjects from both countries were included into this cross-sectional study. Notably, we detected a significant country effect with markedly lower resilience (F=74.4, p<0.001) and self-esteem scores (F=226.0, p<0.001) as well as higher hopelessness scores (F=37.4, p<0.001) among Japanese subjects in general. In addition, both Austrian and Japanese patients indicated significantly lower degrees of resilience (F=57.5, p<0.001), self-esteem (F=51.8, p<0.001), and hope (F=29.5, p<0.001) compared to healthy control subjects. The inter-correlations between subjective elements of recovery were comparable in size in the two patient samples, but the inter-correlations between these issues and residual symptoms of schizophrenia as objective domains of recovery were markedly higher in Austrian subjects. This suggests that schizophrenia patients from Western European and Japanese cultures may have different needs to achieve recovery. In conclusion, it will be critical to develop culture-specific psychosocial programs and to examine their feasibility and effectiveness among these patients.

Mindfulness- and Acceptance-based Interventions for Psychosis: A Systematic Review and Meta-analysis

Background:

Mindfulness- and acceptance-based interventions are increasingly studied as a potential treatment for a variety of mental conditions.

Objective:

To assess the effects of mindfulness- and acceptance-based interventions on psychotic symptoms and hospitalization in patients with psychosis

Methods:

MEDLINE/PubMed, Embase, the Cochrane Library, and PsycINFO were screened from inception through April 2015. Randomized controlled trials (RCTs) were analyzed when they assessed psychotic symptoms or hospitalization in patients with psychosis; affect, acceptance, mindfulness, and safety were defined as secondary outcomes.

Results:

Eight RCTs with a total of 434 patients comparing mindfulness-based (4 RCTs) or acceptance-based interventions (4 RCTs) to treatment as usual or attention control were included. Six RCTs had low risk of bias. Moderate evidence was found for short-term effects on total psychotic symptoms, positive symptoms, hospitalization rates, duration of hospitalization, and mindfulness and for long-term effects on total psychotic symptoms and duration of hospitalization. No evidence was found for effects on negative symptoms, affect, or acceptance. No serious adverse events were reported.

Conclusion:

Mindfulness- and acceptance-based interventions can be recommended as an additional treatment for patients with psychosis.

Mindfulness in schizophrenia: Associations with self-reported motivation, emotion regulation, dysfunctional attitudes, and negative symptoms

Mindfulness-based interventions are gaining empirical support as alternative or adjunctive treatments for a variety of mental health conditions, including anxiety, depression, and substance use disorders. Emerging evidence now suggests that mindfulness-based treatments may also improve clinical features of schizophrenia, including negative symptoms. However, no research has examined the construct of mindfulness and its correlates in schizophrenia. In this study, we examined self-reported mindfulness in patients (n=35) and controls (n=25) using the Five-Facet Mindfulness Questionnaire. We examined correlations among mindfulness, negative symptoms, and psychological constructs associated with negative symptoms and adaptive functioning, including motivation, emotion regulation, and dysfunctional attitudes. As hypothesized, patients endorsed lower levels of mindfulness than controls. In patients, mindfulness was unrelated to negative symptoms, but it was associated with more adaptive emotion regulation (greater reappraisal) and beliefs (lower dysfunctional attitudes). Some facets of mindfulness were also associated with self-reported motivation (behavioral activation and inhibition). These patterns of correlations were similar in patients and controls. Findings from this initial study suggest that schizophrenia patients may benefit from mindfulness-based interventions because they (a) have lower self-reported mindfulness than controls and (b) demonstrate strong relationships between mindfulness and psychological constructs related to adaptive functioning.

Exploring views about mindfulness groups for voice-hearing from the perspective of service users and staff: A Q-methodology study

OBJECTIVES

Despite prevailing beliefs about the potential benefits and harmfulness of mindfulness for people who hear voices, there is a paucity of research into staff and service user views. Q-methodology was used to explore views about mindfulness groups for voice-hearers.

METHOD

Opportunistic sampling of mental healthcare staff (N = 14) and service users with psychosis (N = 17). Both samples were analysed using principle components factor analysis to identify the range of attitudes held by staff and service users.

RESULTS

Staff participants were particularly knowledgeable and interested in mindfulness. A single staff consensus factor was found suggesting mindfulness is helpful, and not harmful for mental health, but uncertainty surrounded its usefulness for voice-hearers. Service users held four distinct attitudes: (i) mindfulness helps to calm a racing mind; (ii) mindfulness helps to manage stress; (iii) mindfulness improves well-being, and does not alter the brain, reality beliefs, or cause madness; and (iv) mindfulness helps with managing thoughts, fostering acceptance, and is acceptable when delivered in a group format.

CONCLUSIONS

Staff viewed mindfulness groups for psychosis as helpful, not harmful, but were uncertain about their utility. Consistent with previous research, service users viewed mindfulness groups as useful to promote well-being and reduce distress for individuals experiencing psychosis.

Standardised mindfulness-based interventions in healthcare: an overview of systematic reviews and meta-analyses of RCTs

BACKGROUND

Mindfulness-based therapies are being used in a wide range of common chronic conditions in both treatment and prevention despite lack of consensus about their effectiveness in different patient categories.

OBJECTIVE

To systematically review the evidence of effectiveness MBSR and MBCT in different patient categories.

METHODS

A systematic review and meta-analysis of systematic reviews of RCTs, using the standardized MBSR or MBCT programs. We used PRISMA guidelines to assess the quality of the included reviews and performed a random effects meta-analysis with main outcome measure Cohen's d. All types of participants were considered.

RESULTS

The search produced 187 reviews: 23 were included, covering 115 unique RCTs and 8,683 unique individuals with various conditions. Compared to wait list control and compared to treatment as usual, MBSR and MBCT significantly improved depressive symptoms (d=0.37; 95%CI 0.28 to 0.45, based on 5 reviews, N=2814), anxiety (d=0.49; 95%CI 0.37 to 0.61, based on 4 reviews, N=2525), stress (d=0.51; 95%CI 0.36 to 0.67, based on 2 reviews, N=1570), quality of life (d=0.39; 95%CI 0.08 to 0.70, based on 2 reviews, N=511) and physical functioning (d=0.27; 95%CI 0.12 to 0.42, based on 3 reviews, N=1015). Limitations include heterogeneity within patient categories, risk of publication bias and limited long-term follow-up in several studies.

CONCLUSION

The evidence supports the use of MBSR and MBCT to alleviate symptoms, both mental and physical, in the adjunct treatment of cancer, cardiovascular disease, chronic pain, depression, anxiety disorders and in prevention in healthy adults and children.

Third-wave strategies for emotion regulation in early psychosis: a pilot study

AIM

Emerging evidence supports the priority of integrating emotion regulation strategies in cognitive behaviour therapy for early psychosis, which is a period of intense distress. Therefore, we developed a new treatment for emotional regulation combining third-wave strategies, namely compassion, acceptance, and mindfulness (CAM) for individuals with early psychosis. The purpose of this study was to examine the acceptability, feasibility and potential clinical utility of CAM.

METHOD

A non-randomized, non-controlled prospective follow-up study was conducted. Outpatients from the First Psychotic Episode Clinic in Montreal were offered CAM, which consisted of 8-week 60-75 min weekly group sessions. Measures of adherence to medication, symptoms, emotional regulation, distress, insight, social functioning and mindfulness were administered at baseline, post-treatment and at 3-month follow up. A short feedback interview was also conducted after the treatment.

RESULTS

Of the 17 individuals who started CAM, 12 (70.6%) completed the therapy. Average class attendance was 77%. Post-treatment feedback indicated that participants found the intervention acceptable and helpful. Quantitative results suggest the intervention was feasible and associated with a large increase in emotional self-regulation, a decrease in psychological symptoms, especially anxiety, depression, and somatic concerns, and improvements in self-care.

CONCLUSION

Overall results support the acceptability, feasibility and potential clinical utility of the new developed treatment. A significant increase in emotional self-regulation and a decrease in affective symptoms were found. No significant changes were observed on measures of mindfulness, insight, distress and social functioning. Controlled research is warranted to validate the effectiveness of the new treatment.

Mindfulness interventions for psychosis: a meta-analysis

BACKGROUND

An increasing number of mindfulness interventions are being used with individuals with psychosis or schizophrenia, but no known meta-analysis has investigated their effectiveness.

OBJECTIVE

To evaluate the efficacy of mindfulness interventions for psychosis or schizophrenia, we conducted an effect-size analysis of initial studies.

DATA SOURCES

A systematic review of studies published in journals or in dissertations in PubMED, PsycINFO or MedLine from the first available date until July 25, 2013.

REVIEW METHODS

A total of 13 studies (n=468) were included.

RESULTS

Effect-size estimates suggested that mindfulness interventions are moderately effective in pre-post analyses (n=12; Hedge's g=.52). When compared with a control group, we found a smaller effect size (n=7; Hedge's g=.41). The obtained results were maintained at follow-up when data were available (n=6; Hedge's g=.62 for pre-post analyses; results only approached significance for controlled analyses, n=3; Hedge's g=.55, p=.08). Results suggested higher effects on negative symptoms compared with positive ones. When combined together, mindfulness, acceptance, and compassion strongly moderated the clinical effect size. However, heterogeneity was significant among the trials, probably due to the diversity of interventions included and outcomes assessed.

CONCLUSION

Mindfulness interventions are moderately effective in treating negative symptoms and can be useful adjunct to pharmacotherapy; however, more research is warranted to identify the most effective elements of mindfulness interventions.

The relationship between psychosocial functioning and resilience and negative symptoms in individuals at ultra-high risk for psychosis

OBJECTIVE

Decline in psychosocial functioning seems to be a core feature in schizophrenia across various phases of the disorder. Little is known about the relationship between psychosocial functioning and protective factors or psychopathologies in individuals in the prodrome phase of psychosis. We aimed to investigate whether psychosocial functioning is impaired in individuals in the putative prodromal phase of schizophrenia, and, if so, to identify factors associated with compromised psychosocial functioning.

METHOD

Sixty participants at ultra-high risk (UHR) for psychosis and 47 healthy controls were recruited. All subjects were assessed in terms of psychosocial functioning using the Quality of Life Scale. A clinical assessment of psychopathology and protective factors, including resilience and coping style, was also conducted.

RESULTS

Psychosocial functioning in UHR participants was found to be compromised; this dysfunction was associated with negative symptoms, adaptive coping, and resilience. In addition, baseline resilience was lower among those in the UHR group who converted to frank psychosis than among those who did not.

CONCLUSIONS

These findings imply that treatment strategies for individuals at UHR for psychosis should be comprehensive, promoting resilience as well as targeting the reduction of positive and negative symptoms to foster social reintegration and recovery.
