Purpose: Medical students have higher rates of depression and psychologic distress than the general population, which may negatively impact academic performance and professional conduct. This study assessed whether 10-20 min of daily mindfulness meditation for 30 days, using a mobile phone application, could decrease perceived stress and improve well-being for medical students. Methods: Eighty-eight medical students were stratified by class year and randomized to either intervention or control groups to use the mobile application Headspace, an audio-guided mindfulness meditation program, for 30 days. All participants completed the Perceived Stress Scale (PSS), Five-Facet Mindfulness Questionnaire (FFMQ), and General Well-Being Schedule (GWBS) at baseline (T1), 30 days (T2), and 60 days (T3). Repeated measures analysis of variance (rANOVA) was conducted for intervention versus control groups across T1, T2, and T3 to examine differences in stress, mindfulness, and well-being. Results: There was a significant interaction between time and treatment group for perceived stress and well-being. Perceived stress significantly decreased for the intervention group from T1 to T3 (F[2,142] = 3.98, p < 0.05). General well-being significantly increased for the intervention group compared to the control group from T1 to T2, and the increase was sustained through T3 (F[2,144] = 3.36, p < 0.05). Conclusions: These results highlight that a mobile audio-guided mindfulness meditation program is an effective means to decrease perceived stress in medical students, which may have implications on patient care. Integrating mindfulness training into medical school curricula for management of school- and work-related stress may lead to fewer negative physician outcomes (e.g., burnout, anxiety, and depression) and improved physician and patient outcomes. This has implications for a broad group of therapists and healthcare providers, ultimately improving quality of healing and patient care. © Copyright 2018, Mary Ann Liebert, Inc.

Background: Emerging evidence suggests that cognitive bias modification of interpretations (CBM-I) is effective in altering interpretation biases and reducing anxiety in adults. Less is known about the impact of CBM-I in young people, but some recent findings, including a meta-analysis of combined cognitive bias modification of interpretation and attention techniques, have cast doubt on its clinical utility. Given the current debate, this meta-analysis sought to establish the independent effects of CBM-I on interpretations biases and anxiety in youth. Methods: Studies were identified through a systematic literature search of PsycINFO, Ovid MEDLINE, PsycARTICLES, Web of Science and EMBASE between January 1992 and March 2017. Eligible studies aimed to target interpretation biases; did not combine CBM-I with another intervention; included a control condition; randomly allocated participants to conditions; assessed interpretation bias and/or anxiety as an outcome; included individuals up to age 18; and did not present previously reported data. Reference lists of included articles were checked for further eligible studies, and authors were contacted for unpublished data. Results: We identified 26 studies meeting eligibility criteria that included in the meta-analysis. CBM-I had moderate effects on negative and positive interpretations (g = -0.70 and g = -0.52, respectively) and a small but significant effect on anxiety assessed after training (g = -0.17) and after a stressor (g = -0.34). No significant moderators were identified. Conclusions: In contrast to previous meta-analytic findings, our results indicate that CBM-I has potential but weak anxiolytic effects in youth. Our findings suggest that it may be premature to disregard the potential value of CBM-I research and further research in this field is warranted.

Behavioral activation (BA) effectively treats depression in adults, and shows promise in treating anxiety. Research into its application to children and adolescents is emerging. This review aimed to explore the scope of studies, current evidence of effectiveness and how the intervention has been delivered and adapted, to inform future research. A systematic review was undertaken searching PsycInfo, PubMed including Medline, EMBASE, and Scopus for terms relating to BA and children and adolescents. Two researchers scored abstracts for inclusion. Data extraction was completed by one researcher and checked by another. 19 studies were identified, across 21 published articles. 12 were case studies, with three pre-post pilot designs and four randomized-controlled trials. Case studies found early support for the feasibility and potential effectiveness of BA to address both anxiety and depression. The RCTs reported largely positive outcomes. Meta-analysis of depression scores indicated that BA may be effective; however, high heterogeneity was observed. Sample sizes to date have been small. BA has been delivered by trained therapists, doctoral trainee psychologists, social workers, or psychology graduates. Studies are uniquely in high-income settings. Adaptations include flexibility in content delivery, youth friendly materials, and parental involvement. There is some limited evidence to support BA as effective for young people. Feasibility and acceptability are supported. Fully powered trials are now required, with expansion to delivery in low- and middle-income settings, and detailed consideration of implementation issues that consider culture and environment.

PURPOSE: Prevention of mental disorders is a rapidly growing area of research with substantial potential benefits for population health. This paper reviews the evidence base for prevention of depression, anxiety, and schizophrenia.
METHODS: We synthesized evidence from recent systematic reviews and meta-analyses published between 2013 and 2018 on prevention of depression, anxiety, and first-episode psychosis. We included reviews of randomized controlled trials testing psychological, psychosocial, and pharmacological preventive interventions.
RESULTS: There is good evidence that depression and anxiety can be prevented, although effect sizes are generally small. Indicated prevention of first-episode psychosis appears promising. Economic evaluations provide support for prevention of depression, anxiety, and first-episode psychosis, but more studies evaluating costs and benefits are needed to strengthen the knowledge base, particularly regarding long-term outcomes, which include chronicity of the prevented disorder, as well as later occurence of important comorbid mental and physical health problems. Promising areas for further development include internet- or computer-based prevention strategies, mindfulness-based interventions, and integration of prevention programs within occupational settings.
CONCLUSIONS: A number of interventions to prevent mental disorders are efficacious. While intervention effect sizes are generally small for prevention of depression and anxiety, they may nonetheless be of significant population benefit. Using the growing evidence base to inform policy and dissemination of evidence-based prevention programs is critical for moving prevention science into real-world settings.

The number of children suffering from stress and anxiety in Malaysia is on the rise. Evidence shows that mind-body therapies such as mindfulness therapy, meditation and yoga have been practiced in many other countries to reduce and/or manage the psychological effects of stress and anxiety. This review article looks at the intervention of yoga as a meditative movement practice in helping school children manage stress and anxiety. Articles were retrieved using a combination of databases including PubMed/MEDLINE, and PsycINFO. Not only peer-reviewed articles, but also those written in English language were included in this review. All studies reviewed had incorporated some form of meditative movement exercise. The intervention encompassed asanas (postures), pranayama (expansion of life force), dharana (concentration) and dhyana (meditation), which are the different paths in yoga. A total of eight articles met the inclusion criteria and were reviewed. The findings of this review reveal that the practice of yoga has brought about, among other things, improvement in managing and reducing stress and anxiety. Despite the limitations in most, if not all of the studies reviewed, in terms of heterogeneity and sample size, yoga appears to be an effective modality for helping children cope with stress and anxiety. It appears that if schools in Malaysia can incorporate yoga as part of the physical education curriculum, it will definitely benefit the students. Copyright © 2017 Shanghai Changhai Hospital

Objective: To determine the trajectory and magnitude of antidepressant response as well as the effect of antidepressant class and dose on symptomatic improvement in pediatric anxiety disorders. Method: Weekly symptom severity data were extracted from randomized, parallel group, placebo-controlled trials of selective serotonin reuptake inhibitors (SSRIs) and selective serotonin-norepinephrine reuptake inhibitors (SNRIs) in pediatric anxiety disorders. Treatment response was modeled for the standardized change in continuous measures of anxiety using Bayesian updating. Posterior distributions for each study served as informative conjugate prior to distributions update subsequent study posteriors. Change in symptom severity was evaluated as a function of time, class and, for SSRIs, standardized dose. Results: Data from 9 trials (SSRIs: n = 5; SNRIs, n = 4) evaluating 7 medications in 1,673 youth were included. In the logarithmic model of treatment response, statistically, but not clinically, significant treatment effects emerged within 2 weeks of beginning treatment (standardized medication-placebo difference = -0.054, credible interval [CI] = -0.076 to -0.032, p =.005, approximate Cohen's d <= 0.2) and by week 6, clinically significant differences emerged (standardized medication-placebo difference = -0.120, CI = -0.142 to -0.097, p =.001, approximate Cohen's d = 0.44). Compared to SNRIs, SSRIs resulted in significantly greater improvement by the second week of treatment (p =.0268), and this advantage remained statistically significant through week 12 (all p values <.03). Improvement occurred earlier with high-dose SSRI treatment (week 2, p =.002) compared to low-dose treatment (week 10, p =.025), but SSRI dose did not have an impact on overall response trajectory (p >.18 for weeks 1-12). Conclusions: In pediatric patients with generalized, separation, and/or social anxiety disorders, antidepressant-related improvement occurred early in the course of treatment, and SSRIs were associated with more rapid and greater improvement compared to SNRIs.

The aim of the present review was to provide an updated investigation of literature from the past ten years that examined the effects of comorbid problems on treatment outcomes, and/or explored if cognitive behavioral treatments (CBT) targeting anxiety disorders also affected comorbid disorders. A search of the literature resulted in a total of 33 publications, based on 28 randomized controlled trials that met predefined inclusion criteria. An analysis of studies that examined whether comorbidity affects treatment outcome yielded mixed results for different types of comorbidities. The inconsistent results were largely due to methodological heterogeneity in the identified studies. Support for negative effects of comorbidity on treatment outcomes was usually found in studies that investigated comorbidity as a categorical diagnosis, rather than symptom levels, and those that analyzed specific comorbid diagnoses, rather than grouping them together. Overall, our findings suggest that comorbid disorders may have a more negative impact on treatment outcomes than proposed in previous reviews, particularly in the cases of comorbid social anxiety and mood disorders. Furthermore, CBT for anxiety disorders in children was found to ameliorate comorbid problems. Copyright © 2017 Elsevier Ltd

Background: Symptoms of depression, anxiety, and distress are more common in undergraduates compared to age-matched peers.Mental ill health among students is associated with impaired academic achievement, worse occupational preparedness, and lower future occupational performance. Research on mental health promoting and mental ill health preventing interventions has shown promising short-term effects, though the sustainability of intervention benefits deserve closer attention. We aimed to identify, appraise and summarize existing data from randomized control trials (RCTs) reporting on whether the effects of mental health promoting and mental ill health preventing interventions were sustained at least three months post-intervention, and to analyze how the effects vary for different outcomes in relation to follow-up length. Further, we aimed to assess whether the effect sustainability varied by intervention type, study-level determinants and of participant characteristics. Material and Methods: A systematic search in MEDLINE, PsycInfo, ERIC, and Scopus was performed for RCTs published in 1995-2015 reporting an assessment of mental ill health and positive mental health outcomes for, at least, three months of post-intervention follow-up. Random-effect modeling was utilized for quantitative synthesis of the existing evidence with standardized mean difference (Hedges' g) used to estimate an aggregated effect size. Sustainability of the effects of interventions was analyzed separately for 3-6 months, 7-12 months, and 13-18 months of post-intervention follow-up. Results: About 26 studies were eligible after reviewing 6,571 citations. The pooled effects were mainly small, but significant for several categories of outcomes. Thus, for the combined mental ill health outcomes, symptom-reduction sustained up to 7-12 months post-intervention (standardized mean difference (Hedges' g) effect size (ES) = -0.28 (95% CI [-0.49, -0.08])). Further, sustainability of symptom-reductions were evident for depression with intervention effect lasting up to 13-18 months (ES = -0.30 (95% CI [-0.51, -0.08])), for anxiety up to 7-12 months (ES = -0.27 (95% CI [-0.54, -0.01])), and for stress up to 3-6 months (ES = -0.30 (95% CI [-0.58, -0.03])). The effects of interventions to enhance positive mental health were sustained up to 3-6 months for the combined positive mental health outcomes (ES = 0.32 (95% CI [0.05, 0.59])). For enhanced active coping, sustainability up to 3-6 months was observed with a medium and significant effect (ES = 0.75 (95% CI [0.19, 1.30])). Discussion: The evidence suggests long-term effect sustainability for mental ill health preventive interventions, especially for interventions to reduce the symptoms of depression and symptoms of anxiety. Interventions to promote positive mental health offer promising, but shorter-lasting effects. Future research should focus on mental health organizational interventions to examine their potential for students in tertiary education. Copyright © 2018 Winzer et al.

Background: Depression and anxiety are the most common mental disorders in children and adolescents. Bibliotherapy is a treatment using written materials for mental health problems. Its main advantages are ease of use, low cost, low staffing demands, and greater privacy. Yet few meta-analyses have focused on the effect of bibliotherapy on depression and anxiety disorders in children and adolescents. Methods: We included randomized controlled trials comparing bibliotherapy with control con-ditions for depression and anxiety in children and adolescents (aged #18 years). Five electronic databases (PubMed, Embase, Cochrane, Web of Science, and PsycINFO) were searched from inception to January 2017. Efficacy was defined as mean change scores in depression and anxiety symptoms. Acceptability was defined as the proportion of participants who discontinued the treatment. Random effects model was used. An intention-to-treat analysis was conducted. Results: Eight studies with 979 participants were selected. At posttreatment, bibliotherapy was significantly more effective than the control conditions in reducing the symptoms of depression or anxiety (standardized mean difference, -0.52; 95% confidence interval [CI], -0.89 to -0.15). Bibliotherapy did not have statistically significantly more all-cause discontinuations than controls (risk ratios, 1.66; 95% CI, 0.93 to 2.95). We also performed subgroup analyses for efficacy outcomes in different categories (types of disorder, mean age, control conditions, and parental involvement) of studies and found that bibliotherapy has been more effective in depressive adolescents. Limitations: Limited studies were eligible in this review and hence there was potential publication bias. Conclusion: According to the findings in this review, bibliotherapy may be more beneficial in treating depression in adolescents, but shows less robust effects for anxiety in children. Further well-defined clinical studies should be performed to confirm these outcomes. Copyright © 2018 Yuan et al.

IMPORTANCE: Childhood anxiety is common. Multiple treatment options are available, but existing guidelines provide inconsistent advice on which treatment to use. OBJECTIVE(S): To evaluate the comparative effectiveness and adverse events of cognitive behavioral therapy (CBT) and pharmacotherapy for childhood anxiety disorders. DATA SOURCES: We searched MEDLINE, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and SciVerse Scopus from database inception through February 1, 2017. STUDY SELECTION: Randomized and nonrandomized comparative studies that enrolled children and adolescents with confirmed diagnoses of panic disorder, social anxiety disorder, specific phobias, generalized anxiety disorder, or separation anxiety and who received CBT, pharmacotherapy, or the combination. DATA EXTRACTION AND SYNTHESIS: Independent reviewers selected studies and extracted data. Random-effects meta-analysis was used to pool data. MAIN OUTCOMES AND MEASURES: Primary anxiety symptoms (measured by child, parent, or clinician), remission, response, and adverse events. RESULT(S): A total of 7719 patients were included from 115 studies. Of these, 4290 (55.6%) were female, and the mean (range) age was 9.2 (5.4-16.1) years. Compared with pill placebo, selective serotonin reuptake inhibitors (SSRIs) significantly reduced primary anxiety symptoms and increased remission (relative risk, 2.04; 95% CI, 1.37-3.04) and response (relative risk, 1.96; 95% CI, 1.60-2.40). Serotonin-norepinephrine reuptake inhibitors (SNRIs) significantly reduced clinician-reported primary anxiety symptoms. Benzodiazepines and tricyclics were not found to significantly reduce anxiety symptoms. When CBT was compared with wait-listing/no treatment, CBT significantly improved primary anxiety symptoms, remission, and response. Cognitive behavioral therapy reduced primary anxiety symptoms more than fluoxetine and improved remission more than sertraline. The combination of sertraline and CBT significantly reduced clinician-reported primary anxiety symptoms and response more than either treatment alone. Head-to-head comparisons were sparse, and network meta-analysis estimates were imprecise. Adverse events were common with medications but not with CBT and were not severe. Studies were too small or too short to assess suicidality with SSRIs or SNRIs. One trial showed a statistically nonsignificant increase in suicidal ideation with venlafaxine. Cognitive behavioral therapy was associated with fewer dropouts than pill placebo or medications. CONCLUSIONS AND RELEVANCE: Evidence supports the effectiveness of CBT and SSRIs for reducing childhood anxiety symptoms. Serotonin-norepinephrine reuptake inhibitors also appear to be effective based on less consistent evidence. Head-to-head comparisons between various medications and comparisons with CBT represent a need for research in the field. Copyright © 2017 American Medical Association. All rights reserved.

Depression and anxiety often emerge for the first time during youth. The school environment provides an ideal context to deliver prevention programs, with potential to offset the trajectory towards disorder. The aim of this review was to provide a comprehensive evaluation of randomised-controlled trials of psychological programs, designed to prevent depression and/or anxiety in children and adolescents delivered in school settings. Medline, PsycINFO and the Cochrane Library were systematically searched for articles published until February 2015. Eighty-one unique studies comprising 31,794 school students met inclusion criteria. Small effect sizes for both depression (g=0.23) and anxiety (g=0.20) prevention programs immediately post-intervention were detected. Small effects were evident after 12-month follow-up for both depression (g=0.11) and anxiety (g=0.13). Overall, the quality of the included studies was poor, and heterogeneity was moderate. Subgroup analyses suggested that universal depression prevention programs had smaller effect sizes at post-test relative to targeted programs. For anxiety, effect sizes were comparable for universal and targeted programs. There was some evidence that externally-delivered interventions were superior to those delivered by school staff for depression, but not anxiety. Meta-regression confirmed that targeted programs predicted larger effect sizes for the prevention of depression. These results suggest that the refinement of school-based prevention programs have the potential to reduce mental health burden and advance public health outcomes.

Objective Despite progress in the development of evidence-based interventions for youth psychiatric problems, up to 75% of youths with mental health needs never receive services, and early dropout is common among those who do. If effective, then single-session interventions (SSIs) for youth psychiatric problems could increase the accessibility, scalability, completion rates, and cost-effectiveness of youth mental health services. This study assessed the effects of SSIs for youth psychiatric problems. Method Using robust variance estimation to address effect size (ES) dependency, findings from 50 randomized-controlled trials (10,508 youths) were synthesized. Results Mean postintervention ES showed a Hedges g value equal to 0.32; the probability that a youth receiving SSI would fare better than a control-group youth was 58%. Effects varied by several moderators, including target problem: ESs were largest for anxiety (0.56) and conduct problems (0.54) and weakest for substance abuse (0.08; targeted in >33% of studies). Other problems yielded numerically promising but nonsignificant ESs (e.g., 0.21 for depression), potentially from low representation across trials. ESs differed across control conditions, with larger ESs for studies with no treatment (0.41) versus active controls (0.14); developmental periods, with greater ESs for children (0.42) than adolescents (0.19); intervention types, with largest ESs for youth-focused cognitive-behavioral approaches (0.74); and follow-up lengths, with smaller ESs for follow-ups exceeding 13 weeks. ESs did not differ for self- versus therapist-administered interventions or for youths with diagnosable versus subclinical problems. Conclusion Findings support the promise of SSIs for certain youth psychiatric problems and the need to clarify how, to what degree, and for whom SSIs effect lasting change.
