Mindfulness-based cognitive therapy for children and adolescents with anxiety disorders at-risk for bipolar disorder: A psychoeducation waitlist controlled pilot trial

Preventive interventions for individuals at risk of developing bipolar disorder: A systematic review and meta-analysis

BACKGROUND

This systematic review and meta-analysis aimed to explore whether early interventions can reduce affective symptoms and have long-term benefits among individuals at risk of bipolar disorder (BD).

METHODS

The PubMed, Embase, and Web of Science databases were searched. The primary outcome was continuous symptom scores before and after treatment. Random effects meta-analyses were conducted for each outcome arm studied and pooled mean difference estimates were calculated.

RESULTS

The search identified 10 controlled studies involving 425 participants and 6 single-arm studies involving 90 participants. For controlled trials, meta-analysis showed that the interventions led to greater reduction in clinical global score than placebo (standardized mean differences (SMD) = -0.96, 95 % CI:-1.32, -0.60), and supported a long-term longitudinal effect for pharmacotherapy (SMD = -0.42, 95 % CI: -0.79, -0.05). For single-arm trials, both pharmacotherapy and psychotherapy showed efficacy for depressive symptoms, while pharmacotherapy only showed efficacy for hypomania symptoms (effect size (ES) = -9.16, 95 % CI:-11.29, -7.04). Discontinuation of pharmacotherapy due to adverse effects did not show a difference.

LIMITATIONS

The primary limitations are the small number of RCTs and the influence of medication dosage.

CONCLUSIONS

Based on the limited available data, early interventions show efficacy for individuals at risk of BD. Psychological therapy might be more beneficial for depressive symptoms and have long-term benefits for hypomania. Pharmacotherapy may be appropriate in situations of severe hypomanic symptoms and the poor functioning. Large, well-designed, double-blind -controlled trials are needed to make solid conclusions about the efficacy of early interventions.

Review: Adverse event monitoring and reporting in studies of pediatric psychosocial interventions: a systematic review

BACKGROUND

Adverse event monitoring in studies of psychotherapy is crucial to clinical decision-making, particularly for weighing of benefits and harms of treatment approaches. In this systematic review, we identified how adverse events are defined, measured, and reported in studies of psychosocial interventions for children with mental disorders.

METHOD

Medline, PsycINFO, Embase, ProQuest Dissertations and Theses Global, and the Cochrane Library were searched from January 2011-January 2023, and Google Scholar from January 2011-February 2023. English language experimental and quasi-experimental studies that evaluated the efficacy or effectiveness of psychosocial interventions for childhood mental disorders were included. Information on the definition, assessment, and report of adverse events was extracted using a checklist based on Good Clinical Practice guidelines.

RESULTS

In this review, 117 studies were included. Studies most commonly involved treating anxiety disorders or obsessive-compulsive disorder (32/117; 27%); 44% of the experimental interventions tested (52/117) were cognitive behavioral therapies. Adverse events were monitored in 36 studies (36/117; 31%) with a protocol used in 19 of these studies to guide monitoring (19/36; 53%). Twenty-seven different events were monitored across the studies with hospitalization the most frequently monitored (3/36; 8%). Event severity was fully assessed in 6 studies (17%) and partially assessed in 12 studies (33%). Only 4/36 studies (11%) included assessing events for cause.

CONCLUSIONS

To date, adverse events have been inconsistently defined, measured and reported in psychosocial intervention studies of childhood mental health disorders. Information on adverse events is an essential knowledge component for understanding the potential impacts and risks of therapeutic interventions.

Child and adolescent anxiety as a risk factor for bipolar disorder: A systematic review of longitudinal studies

OBJECTIVES

Several studies have suggested that anxiety disorders in childhood and adolescence often precede the onset of bipolar disorder. We therefore systematically reviewed the relationship between child and adolescent anxiety and later bipolar disorder.

METHODS

Online databases (Medline [for Ovid], EMBASE and PsychINFO) were searched for original, peer-reviewed studies examining the relationship between child and adolescent anxiety and later bipolar disorder. Studies in both community samples and bipolar offspring samples were included.

RESULTS

A total of 16 studies were included in the review. The results were broadly consistent and revealed that child and adolescent anxiety disorders are associated with later bipolar disorder in community samples. In bipolar offspring, child and adolescent anxiety disorders are a marker of increased risk and predict the onset of bipolar disorder and other major mood disorders.

CONCLUSIONS

There is evidence that anxiety disorders in childhood and adolescence increase the risk of later bipolar disorder. Anxiety disorders may be a useful target for early intervention in those at high-risk of bipolar disorder.

Anxiety in bipolar disorder: A review of publication trends

BACKGROUND

Although anxiety is highly prevalent in people with bipolar disorders and has deleterious impact on the course of the illness, past reviews have shown that many aspects of the topic remain under-researched. This scoping review aims to provide a comprehensive overview of the literature addressing anxiety in bipolar disorder (A-BD) between 2011 and 2020, assess if the interest in the topic has increased over the period and map the publication trends.

METHODS

Three databases were systematically searched, and all articles were screened at the title/abstract and full text level based on inclusion and exclusion criteria. Of these, 1099 articles were included in the study. The annual number of articles on A-BD published between 2011 and 2020 was calculated and articles addressing it as a primary topic (n = 310) were classified into 4 categories and 11 subcategories to identify gaps in the knowledge.

RESULTS

The results show no clear increase in the number of annual publications during the period and much of the available literature is of a descriptive nature. Less is known about the processes underlying the comorbidity and about treatment approaches.

LIMITATIONS

Given the large scope of the research question, no quality assessment of the evidence was made. Only articles in English or French were considered.

CONCLUSIONS

These results highlight the need to change the focus of research efforts to better understand and address this unique set of conditions in clinical settings.

The Effectiveness of Psychoeducational Interventions in Adolescents’ Anxiety: A Systematic Review Protocol

The COVID-19 pandemic had a strong impact on increasing anxiety in adolescents. This systematic review aims to identify the most effective psychoeducational interventions for reducing anxiety in adolescents following the guidelines of the Joanna Briggs Institute (JBI). The inclusion and exclusion criteria have been defined, and the search strategy has been planned. The search strategy will aim to locate both published and unpublished studies using, among other databases: CINAHL Plus with Full Text; PubMed; the Cochrane Central Register of Controlled Trials; and the JBI Database of Systematic Reviews. Following the search, all identified citations will be collated and uploaded into Endnote, and duplicates removed. Titles and abstracts will then be screened by two independent reviewers and by a third reviewer if a disagreement occurs. The results of the search will be reported in full in the final systematic review and presented in the PRISMA flow diagram. Eligible studies will be critically appraised for methodological quality using standardized critical appraisal instruments from the JBI. Data will be extracted from the studies included using the standardized JBI data extraction tool. For data synthesis, studies will be pooled using JBI SUMARI. The GRADE approach for grading the certainty of evidence will be followed, and a summary of findings will be created using GRADEPro GDT software. The results from this systematic review are expected to provide an overview of the most effective psychoeducational interventions for reducing anxiety in adolescents, allowing researchers to design and propose a new multicomponent psychoeducational intervention that will be validated and tested in the future. PROSPERO protocol registration number: CRD42020204356.

Psychosocial Treatments for Bipolar Disorder in Children and Adolescents

Evidence suggests that adjunctive psychosocial intervention for the treatment of pediatric bipolar spectrum disorders (BPSDs) is effective, feasible, and highly accepted as both an acute and maintenance treatment for youth with BPSD diagnoses as well as a preventive treatment for high-risk youth who are either asymptomatic or exhibit subsyndromal mood symptoms. Here, we provide a comprehensive review of all known evidence-based interventions, including detailed descriptions of treatment targets and core components, results of clinical trials, and updated research on mediators and moderators of treatment efficacy. Treatments are presented systematically according to level of empirical support (i.e., well established, probably efficacious, possibly efficacious, experimental, or questionable); upcoming and ongoing trials are included when possible. In line with a staging approach, preventive interventions are presented separately. Recommendations for best practices based on age, stage, and additional evidence-based child and family factors shown to affect treatment outcomes are provided. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 18 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

A Meta-Analytic Review of Emotion Regulation Focused Psychosocial Interventions for Adolescents

Emotion regulation (ER) is the ability to monitor, evaluate, and modify one's emotional responses to be appropriate for environmental demands. Poor ER has been considered a transdiagnostic risk factor for a range of internalizing and externalizing disorders and overall decreased well-being in adolescents. A range of evidence-based interventions exist which may improve ER. However, much of the intervention research to date does not include a measure of ER to assess change pre and post treatment, with limited information about the efficacy of these interventions in youth across a range of sample types. There is a clear need for a comprehensive review of the literature examining ER-focused interventions in adolescents with a wide range of presenting disorders. A literature search was originally conducted in January 2020 and an updated search was conducted in February 2021 which elicited 1245 articles, of which 605 were duplicates and were removed. Abstracts of the remaining 640 articles were screened with 121 articles being reviewed in full. Of note, 16 additional articles were identified through references and other sources during this process and were also included in the full review. Of the 137 articles reviewed in full, 41 studies were ultimately included in the present review. The present paper provides a descriptive review of intervention approaches and findings from community prevention programs, programs for war-affected youth, programs for clinical populations, and programs for incarcerated and delinquent adolescents. The overall pooled effect was significantly different from zero based on the pre/post effects [Hedge's g = 0.29, 95% CI (0.22, 0.36)] and the intervention/control effects [Hedge's g = 0.19, 95% CI (0.06-0.32)]. Although neither sex nor age significantly accounted for heterogeneity in effect sizes, there were significant findings for population type (clinical vs. community), with community samples having significantly lower effect sizes on average. Impacts of the different ER measures used and significant methodological variability (e.g., use of control groups, length of intervention) across included studies are discussed. Implications and suggestions for future research are reviewed, specifically, that additional understanding of moderators of effects are needed and that measures used to assess change in ER, both dysregulation and adaptive skill use, may need to more directly align with the intervention's focus and the strategies taught as part of the intervention.

Mental health benefits of a 1-week intensive multimodal group program for adolescents with multiple adverse childhood experiences

BACKGROUND

Adverse childhood experiences (ACEs) are associated with a wide range of diseases, unsafe behavior and shorter life expectancy. However, there is scarce evidence on effective interventions for children or adolescents who report multiple ACEs, including abuse, neglect and household dysfunction.

OBJECTIVE

The aim of this study was to evaluate the mental health outcomes of a multimodal program designed for adolescents with multiple ACEs.

PARTICIPANTS

Forty-four girls (aged 13-16 years, mean ACE score > 5) were randomized to an intervention group or a care-as-usual control group.

METHODS

The intervention included mindfulness-based practices, expressive arts and EMDR (Eye Movement Desensitization and Reprocessing Integrative) group treatment. We used questionnaires for adolescents to assess trauma (SPRINT, CPSS) and attention/awareness-related outcomes (MAAS-A) at baseline (T1), post-intervention (T2) and two-months post-discharge (T3).

RESULTS

Linear mixed effects model analyses showed significant Group by Time interactions on all the scales (F = 11.0, p = 0.015; F = 12.5 p < 0.001; and F = 6.4, p = 0.001, for SPRINT, CPSS and MAAS-A, respectively). After completing the program, the intervention group showed significant reduction in trauma-related outcomes (SPRINT, Δ%_(T2-T1) = -73%, p < 0.001; CPSS, Δ%_(T2-T1) = -26%, p < 0.001) while attention/awareness-related outcomes were improved by 57% (p < 0.001). These changes remained stable two months after discharge. SPRINT and CPSS scales were highly correlated (r = 0.833, p < 0.001) and outcomes from both trauma-related scales negatively correlated with mindfulness scores (MAAS-A/SPRINT, r = -0.515, p = 0.007; MAAS-A/CPSS, r = -0.553, p < 0.001).

CONCLUSIONS

Results presented here support this multimodal group intervention as a feasible and promising program for reducing the psychological burden in adolescents with a history of multiple ACEs.

The Management of Prodromal Symptoms of Bipolar Disorder: Available Options and Future Perspectives

The onset of prodromal symptoms in subjects who are at familial or clinical risk for bipolar disorder could be considered as an important alarm bell for the development of the disease and should be carefully detected. The management of prodromes in bipolar high-risk patients appears to be an important means of prevention; nevertheless, at the moment, there aren’t clear and widely shared treatment indications. The aim of this review is to summarize the available treatment options (pharmacological, psychosocial and nutraceutical) for the management of prodromal symptoms in subjects who are at familial or clinical risk for bipolar disorder.

Network-level functional topological changes after mindfulness-based cognitive therapy in mood dysregulated adolescents at familial risk for bipolar disorder: a pilot study

BACKGROUND

Given that psychopharmacological approaches routinely used to treat mood-related problems may result in adverse outcomes in mood dysregulated adolescents at familial risk for bipolar disorder (BD), Mindfulness-Based Cognitive Therapy for Children (MBCT-C) provides an alternative effective and safe option. However, little is known about the brain mechanisms of beneficial outcomes from this intervention. Herein, we aimed to investigate the network-level neurofunctional effects of MBCT-C in mood dysregulated adolescents.

METHODS

Ten mood dysregulated adolescents at familial risk for BD underwent a 12-week MBCT-C intervention. Resting-state functional magnetic resonance imaging (fMRI) was performed prior to and following MBCT-C. Topological metrics of three intrinsic functional networks (default mode network (DMN), fronto-parietal network (FPN) and cingulo-opercular network (CON)) were investigated respectively using graph theory analysis.

RESULTS

Following MBCT-C, mood dysregulated adolescents showed increased global efficiency and decreased characteristic path length within both CON and FPN. Enhanced functional connectivity strength of frontal and limbic areas were identified within the DMN and CON. Moreover, change in characteristic path length within the CON was suggested to be significantly related to change in the Emotion Regulation Checklist score.

CONCLUSIONS

12-week MBCT-C treatment in mood dysregulated adolescents at familial risk for BD yield network-level neurofunctional effects within the FPN and CON, suggesting enhanced functional integration of the dual-network. Decreased characteristic path length of the CON may be associated with the improvement of emotion regulation following mindfulness training. However, current findings derived from small sample size should be interpreted with caution. Future randomized controlled trials including larger samples are critical to validate our findings.

Research Review: Pediatric anxiety disorders - what have we learnt in the last 10 years?

BACKGROUND

Anxiety disorders first emerge during the critical developmental periods of childhood and adolescence. This review synthesizes recent findings on the prevalence, risk factors, and course of the anxiety disorders; and their neurobiology and treatment.

METHODS

For this review, searches were conducted using PubMed, PsycINFO, and clinicaltrials.gov. Findings related to the epidemiology, neurobiology, risk factors, and treatment of pediatric anxiety disorders were then summarized.

FINDINGS

Anxiety disorders are high prevalence, and early-onset conditions associated with multiple risk factors including early inhibited temperament, environment stress, and structural and functional abnormalities in the prefrontal-amygdala circuitry as well as the default mode and salience networks. The anxiety disorders are effectively treated with cognitive behavioral therapy (CBT), selective serotonin reuptake inhibitors (SSRIs), and serotonin-norepinephrine reuptake inhibitors (SNRIs).

CONCLUSIONS

Anxiety disorders are high prevalence, early-onset conditions associated with a distinct neurobiological fingerprint, and are consistently responsive to treatment. Questions remain regarding who is at risk of developing anxiety disorders as well as the way in which neurobiology predicts treatment response.

Early intervention for people at high risk of developing bipolar disorder: a systematic review of clinical trials

Early intervention approaches are built on the premise of preventing disability, burden, and cognitive sequelae caused by bipolar disorder. The objective of this systematic review was to characterise the effectiveness of all the available psychological and pharmacological treatments for early intervention in people at high risk of developing bipolar disorder. The study was registered with PROSPERO (CRD42019133420). We did a systematic search to identify studies published in ten databases up to March 27, 2020. Randomised controlled trials and cohort studies that assessed the effect of pharmacological or psychological interventions in people at high risk of developing bipolar disorder were included. Studies of first episodes of mania were excluded. Eligible papers were assessed for quality and data were extracted. The primary outcomes were change in manic and depressive symptoms from baseline to endpoint. Of the 2856 citations retrieved by our search, 16 studies were included; five evaluated pharmacotherapeutic strategies (three randomised controlled trials and two open-label studies), ten assessed psychotherapeutic strategies (four randomised controlled trials and six open-label studies), and one randomised controlled trial assessed combination therapy; these 16 trials included a total of 755 participants at high risk of developing bipolar disorder. Quality assessment indicated fair to good quality for open-label studies, and a high risk of bias in four randomised controlled trials. Among the pharmacotherapeutic interventions, there is preliminary support for the efficacy of aripiprazole in reducing mood symptoms in people at high risk of developing bipolar disorder. Psychological interventions were effective for various outcomes. There was substantial methodological heterogeneity across studies. This systematic review underscores the need for multicentre, prospective, methodologically homogeneous studies evaluating conversion to bipolar disorder as an outcome measure.

Cognitive behavioural therapy for anxiety disorders in children and adolescents

BACKGROUND

Previous Cochrane Reviews have shown that cognitive behavioural therapy (CBT) is effective in treating childhood anxiety disorders. However, questions remain regarding the following: up-to-date evidence of the relative efficacy and acceptability of CBT compared to waiting lists/no treatment, treatment as usual, attention controls, and alternative treatments; benefits across a range of outcomes; longer-term effects; outcomes for different delivery formats; and amongst children with autism spectrum disorders (ASD) and children with intellectual impairments.

OBJECTIVES

To examine the effect of CBT for childhood anxiety disorders, in comparison with waitlist/no treatment, treatment as usual (TAU), attention control, alternative treatment, and medication.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Controlled Trials Register (all years to 2016), the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and PsycINFO (each to October 2019), international trial registries, and conducted grey literature searches.

SELECTION CRITERIA

We included randomised controlled trials of CBT that involved direct contact with the child, parent, or both, and included non-CBT comparators (waitlist/no treatment, treatment as usual, attention control, alternative treatment, medication). Participants were younger than age 19, and met diagnostic criteria for an anxiety disorder diagnosis. Primary outcomes were remission of primary anxiety diagnosis post-treatment, and acceptability (number of participants lost to post-treatment assessment), and secondary outcomes included remission of all anxiety diagnoses, reduction in anxiety symptoms, reduction in depressive symptoms, improvement in global functioning, adverse effects, and longer-term effects.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as recommended by Cochrane. We used GRADE to assess the quality of the evidence.

MAIN RESULTS

We included 87 studies and 5964 participants in quantitative analyses. Compared with waitlist/no treatment, CBT probably increases post-treatment remission of primary anxiety diagnoses (CBT: 49.4%, waitlist/no treatment: 17.8%; OR 5.45, 95% confidence interval (CI) 3.90 to 7.60; n = 2697, 39 studies, moderate quality); NNTB 3 (95% CI 2.25 to 3.57) and all anxiety diagnoses (OR 4.43, 95% CI 2.89 to 6.78; n = 2075, 28 studies, moderate quality). Low-quality evidence did not show a difference between CBT and TAU in post-treatment primary anxiety disorder remission (OR 3.19, 95% CI 0.90 to 11.29; n = 487, 8 studies), but did suggest CBT may increase remission from all anxiety disorders compared to TAU (OR 2.74, 95% CI 1.16 to 6.46; n = 203, 5 studies). Compared with attention control, CBT may increase post-treatment remission of primary anxiety disorders (OR 2.28, 95% CI 1.33 to 3.89; n = 822, 10 studies, low quality) and all anxiety disorders (OR 2.75, 95% CI 1.22 to 6.17; n = 378, 5 studies, low quality). There was insufficient available data to compare CBT to alternative treatments on post-treatment remission of primary anxiety disorders, and low-quality evidence showed there may be little to no difference between these groups on post-treatment remission of all anxiety disorders (OR 0.89, 95% CI 0.35 to 2.23; n = 401, 4 studies) Low-quality evidence did not show a difference for acceptability between CBT and waitlist/no treatment (OR 1.09, 95% CI 0.85 to 1.41; n=3158, 45 studies), treatment as usual (OR 1.37, 95% CI 0.73 to 2.56; n = 441, 8 studies), attention control (OR 1.00, 95% CI 0.68 to 1.49; n = 797, 12 studies) and alternative treatment (OR 1.58, 95% CI 0.61 to 4.13; n=515, 7 studies). No adverse effects were reported across all studies; however, in the small number of studies where any reference was made to adverse effects, it was not clear that these were systematically monitored. Results from the anxiety symptom outcomes, broader outcomes, longer-term outcomes and subgroup analyses are provided in the text. We did not find evidence of consistent differences in outcomes according to delivery formats (e.g. individual versus group; amount of therapist contact time) or amongst samples with and without ASD, and no studies included samples of children with intellectual impairments.

AUTHORS' CONCLUSIONS

CBT is probably more effective in the short-term than waiting lists/no treatment, and may be more effective than attention control. We found little to no evidence across outcomes that CBT is superior to usual care or alternative treatments, but our confidence in these findings are limited due to concerns about the amount and quality of available evidence, and we still know little about how best to efficiently improve outcomes.

Medication exposure and predictors of first mood episode in offspring of parents with bipolar disorder: a prospective study

OBJECTIVES

To prospectively investigate whether baseline clinical characteristics and medication exposure predict development of major depressive disorder or bipolar disorder in offspring of parents with bipolar disorder.

METHODS

Youth aged 9-20 years with at least one biological parent with bipolar disorder and no prior history of mood or psychotic episodes (n=93) were prospectively evaluated and treated naturalistically during the study. Participants were divided into two groups: converters, defined as those who met DSM-IV criteria for a mood episode during follow-up (n=19); or non-converters (n=74). Logistic regression models were used to investigate associations between baseline clinical variables and medication exposure during follow-up and risk of developing a first mood episode (conversion).

RESULTS

Multivariate regression analyses showed that baseline anxiety disorders and subsyndromal mood disorders were associated with increased risk of conversion during follow-up. Adding medication exposure to the multivariate model showed that exposure to antidepressants during follow-up was associated with increased risk of conversion.

CONCLUSIONS

Caution should be used when treating bipolar offspring with anxiety and/or emerging depressive symptoms using antidepressant agents, given the increased risk of developing a major mood disorder.

[Mindfulness in Trainee Psychotherapies with Children and Adolescents]

Mindfulness in Trainee Psychotherapies with Children and Adolescents The implementation of mindfulness-based interventions (MBIs) in cognitive-behavioral therapy has greatly increased over the past few years. However, there is little research about the implementation of MBIs in individual child and adolescent psychotherapy. The present paper gives an overview of current MBIs and their efficacy in children and adolescents. A depiction of the implementation of MBIs in individual therapy and a description of the "Mindfulness and Relaxation Study - Children and Adolescents" (MARS-CA) is given. The study aims to examine the effects of short session-introducing interventions with mindfulness elements on juvenile patients' psychopathological symptomatology and therapeutic alliance. For this reason, the authors compare session-introducing interventions with mindfulness elements with session-introducing relaxation interventions and no session-introducing intervention. Qualitative results of the pre-study show that both interventions with mindfulness elements and relaxation interventions work well with juvenile patients.

Toward prevention of bipolar disorder in at-risk children: Potential strategies ahead of the data

BACKGROUND

Despite the well-documented negative impact of untreated bipolar illness, approaches to early intervention in childhood-onset bipolar and related disorders are not well delineated.

METHODS

We reviewed the extant treatment literature on children at high risk for bipolar disorder, with definitions based on family history, childhood adversity, and prodromal symptoms.

RESULTS

A panoply of approaches have been described, but most interventions are based on an inadequate database to support their routine implementation. We classify early stage interventions as a function of their safety and tolerability with the hope that these might generate more rigorous study and a stronger database.

LIMITATIONS

Critics may rightly argue that identifying viable treatment methods is premature given our lack of ability to reliably predict illness trajectory in very young children. However, many of the psychosocial and pharmacological interventions we present could have nonspecific positive effects across a variety of symptoms, syndromes, and diagnoses, further enhancing the rationale for more rigorous study.

CONCLUSIONS

Early stage interventions have the potential to improve functioning in prodromal illness and exert long-term positive effects on the course of illness. Many of the safest interventions deserve consideration for implementation and dissemination studies.
