Maternal psychological distress could affect gut microbiota of the infant; however, previous studies to date have been observational.
To investigate the effects of mindfulness-based intervention ...(MBI) during pregnancy on the meconium microbiota of infants by alleviating maternal psychological distress.
Randomized controlled trial.
Pregnant women with symptoms of depression or anxiety were randomized to either the intervention group (n = 80), comprising usual perinatal care and six digitally guided self-help MBI sessions, or the control group (n = 80) who underwent usual perinatal care. Meconium was collected within 48 h of birth to evaluate the infant's gut microbiota. The Kruskal–Wallis rank sum test, analysis of similarities, and DESeq2 were performed to explore the effects of the MBI on alpha and beta diversity indices and specific genera.
There were no significant differences between groups regarding the alpha diversity indices, including Chao1 and Simpson (p = 0.83 and p = 0.58). However, there was a significant between-group difference in the beta diversity index (R=0.02, p = 0.03). Bifidobacterium (log2 fold change=−1.90, FDR=0.002) and Blautia (log2 fold change=−1.45, FDR=0.01) were abundant in the intervention group, whereas Staphylococcus (log2 fold change=1.44, FDR=0.01) was abundant in the control group.
MBI aimed at alleviating maternal psychological distress can positively alter the meconium microbiota of infants. However, the mechanisms underlying the effects of maternal mindfulness during pregnancy on infant meconium microbiota require further exploration.
•MBI did not affect alpha diversity but significantly impacted beta diversity.•Bifidobacterium and Blautia were abundant after MBI.•Staphylococcus was abundant in the control without MBI.•Mindfulness intervention could enhance offspring health.
Background
Research investigating the role of emotion regulation (ER) in the development and treatment of psychopathology has increased in recent years. Evidence suggests that an increased focus on ...ER in treatment can improve existing interventions. Most ER research has neglected young people, therefore the present meta-analysis summarizes the evidence for existing psychosocial intervention and their effectiveness to improve ER in youth. A systematic review and meta-analysis was conducted according to the PRISMA guidelines. Twenty-one randomized-control-trials (RCTs) assessed changes in ER following a psychological intervention in youth exhibiting various psychopathological symptoms. We found moderate effect sizes for current interventions to decrease emotion dysregulation in youth (
g
= − 0.46) and small effect sizes to improve emotion regulation (
g
= 0.36). Significant differences between studies including intervention components, ER measures and populations studied resulted in large heterogeneity. This is the first meta-analysis that summarizes the effectiveness for existing interventions to improve ER in youth. The results suggest that interventions can enhance ER in youth, and that these improvements correlate with improvements in psychopathology. More RCTs including larger sample sizes, different age groups and psychopathologies are needed to increase our understanding of what works for who and when.
•We included 62 studies from 17 countries assessing psychological distress of COVID-19.•We found a high psychological burden among medical staff and the general public.•However, the psychological ...distress was significantly higher among patients.•We identified risk factors of psychological burdens to identify high-risk people.•Professional medical services should be allocated to high-risk population.•More self-help materials should be made available for people with milder impact.
The coronavirus disease 2019 (COVID-19) pandemic has caused enormous psychological impact worldwide. We conducted a systematic review and meta-analysis on the psychological and mental impact of COVID-19 among healthcare workers, the general population, and patients with higher COVID-19 risk published between 1 Nov 2019 to 25 May 2020. We conducted literature research using Embase, PubMed, Google scholar and WHO COVID-19 databases. Among the initial search of 9207 studies, 62 studies with 162,639 participants from 17 countries were included in the review. The pooled prevalence of anxiety and depression was 33% (95% confidence interval: 28%-38%) and 28% (23%-32%), respectively. The prevalence of anxiety and depression was the highest among patients with pre-existing conditions and COVID-19 infection (56% 39%-73% and 55% 48%-62%), and it was similar between healthcare workers and the general public. Studies from China, Italy, Turkey, Spain and Iran reported higher-than-pooled prevalence among healthcare workers and the general public. Common risk factors included being women, being nurses, having lower socioeconomic status, having high risks of contracting COVID-19, and social isolation. Protective factors included having sufficient medical resources, up-to-date and accurate information, and taking precautionary measures. In conclusion, psychological interventions targeting high-risk populations with heavy psychological distress are in urgent need.
Major depressive disorder (MDD) is highly disabling and typically runs a recurrent course. Knowledge about prevention of relapse and recurrence is crucial to the long-term welfare of people who ...suffer from this disorder. This article provides an overview of the current evidence for the prevention of relapse and recurrence using psychological interventions. We first describe a conceptual framework to preventive interventions based on: acute treatment; continuation treatment, or; prevention strategies for patients in remission. In brief, cognitive-behavioral interventions, delivered during the acute phase, appear to have an enduring effect that protects patients against relapse and perhaps others from recurrence following treatment termination. Similarly, continuation treatment with either cognitive therapy or perhaps interpersonal psychotherapy appears to reduce risk for relapse and maintenance treatment appears to reduce risk for recurrence. Preventive relapse strategies like preventive cognitive therapy or mindfulness based cognitive therapy (MBCT) applied to patients in remission protects against subsequent relapse and perhaps recurrence. There is some preliminary evidence of specific mediation via changing the content or the process of cognition. Continuation CT and preventive interventions started after remission (CBT, MBCT) seem to have the largest differential effects for individuals that need them the most. Those who have the greatest risk for relapse and recurrence including patients with unstable remission, more previous episodes, potentially childhood trauma, early age of onset. These prescriptive indications, if confirmed in future research, may point the way to personalizing prevention strategies. Doing so, may maximize the efficiency with which they are applied and have the potential to target the mechanisms that appear to underlie these effects. This may help make this prevention strategies more efficacious.
•CBT delivered during the acute phase, does appear to have an enduring effect.•Continuation psychological treatment appears to reduce risk for relapse.•Preventive interventions have the largest effects for ultra high-risk individuals.
Evidence for the effectiveness of psychological interventions for schizophrenia/psychosis is growing, however there is no consensus on the psychological intervention most likely to reduce symptoms.
A ...network meta-analysis was conducted to identify all randomised controlled trials (RCTs) of psychological interventions for adults with schizophrenia/psychosis. A systematic review of the literature using MEDLINE, PsycINFO, EMBASE and CENTRAL led to an analysis of 90 RCTs with 8440 randomised participants across 24 psychological intervention, and control groups. Psychological interventions were categorised and rated for treatment fidelity and risk of bias. Data for total symptoms were extracted and network meta-analysis, using a frequentist approach, was undertaken using Stata SE v15 to compare the direct and indirect evidence for the effectiveness of each psychological intervention.
Psychological interventions were more likely to reduce symptoms than control groups, and one intervention, mindfulness-based psychoeducation, was consistently ranked as most likely to reduce total symptoms. Subgroup analyses identified differential effectiveness in different settings and for different subgroups.
Mindfulness-based psychoeducation was consistently ranked as most likely to reduce symptoms; however all studies were based in China. More RCTs in a variety of cultural contexts would help to elucidate whether these findings generalise internationally. A number of psychological interventions could potentially be more effective than interventions recommended by NICE guidelines, such as CBT and family therapy, and additional RCTs and meta-analyses are needed to generate more conclusive evidence in this regard.
Background
Suicide is a leading cause of death and a complex clinical outcome. Here, we summarize the current state of research pertaining to suicidal thoughts and behaviors in youth. We review their ...definitions/measurement and phenomenology, epidemiology, potential etiological mechanisms, and psychological treatment and prevention efforts.
Results
We identify key patterns and gaps in knowledge that should guide future work. Regarding epidemiology, the prevalence of suicidal thoughts and behaviors among youth varies across countries and sociodemographic populations. Despite this, studies are rarely conducted cross‐nationally and do not uniformly account for high‐risk populations. Regarding etiology, the majority of risk factors have been identified within the realm of environmental and psychological factors (notably negative affect‐related processes), and most frequently using self‐report measures. Little research has spanned across additional units of analyses including behavior, physiology, molecules, cells, and genes. Finally, there has been growing evidence in support of select psychotherapeutic treatment and prevention strategies, and preliminary evidence for technology‐based interventions.
Conclusions
There is much work to be done to better understand suicidal thoughts and behaviors among youth. We strongly encourage future research to: (1) continue improving the conceptualization and operationalization of suicidal thoughts and behaviors; (2) improve etiological understanding by focusing on individual (preferably malleable) mechanisms; (3) improve etiological understanding also by integrating findings across multiple units of analyses and developing short‐term prediction models; (4) demonstrate greater developmental sensitivity overall; and (5) account for diverse high‐risk populations via sampling and reporting of sample characteristics. These serve as initial steps to improve the scientific approach, knowledge base, and ultimately prevention of suicidal thoughts and behaviors among youth.

Following 2 decades of research on cognitive behavioral therapy for psychosis (CBTp), it is relevant to consider at which point the evidence base is considered sufficient. We completed a cumulative ...meta-analysis to assess the sufficiency and stability of the evidence base for hallucinations and delusions.
We updated the systematic search from our previous meta-analytic review from August 2013 until December 2019. We identified 20 new randomized controlled trials (RCTs) resulting in inclusion of 35 RCTs comparing CBTp with treatment-as-usual (TAU) or active controls (AC). We analyzed data from participants with psychosis (N = 2407) over 75 conventional meta-analytic comparisons. We completed cumulative meta-analyses (including fail-safe ratios) for key comparisons. Publication bias, heterogeneity, and risk of bias were examined.
Cumulative meta-analyses demonstrated sufficiency and stability of evidence for hallucinations and delusions. The fail-safe ratio demonstrated that the evidence base was sufficient in 2016 for hallucinations and 2015 for delusions. In conventional meta-analyses, CBTp was superior for hallucinations (g = 0.34, P < .01) and delusions (g = 0.37, P < .01) when compared with any control. Compared with TAU, CBTp demonstrated superiority for hallucinations (g = 0.34, P < .01) and delusions (g = 0.37, P < .01). Compared with AC, CBT was superior for hallucinations (g = 0.34, P < .01), but not for delusions although this comparison was underpowered. Sensitivity analyses for case formulation, primary outcome focus, and risk of bias demonstrated increases in effect magnitude for hallucinations.
The evidence base for the effect of CBTp on hallucinations and delusions demonstrates sufficiency and stability across comparisons, suggesting limited value of new trials evaluating generic CBTp.
To draw causal conclusions about the efficacy of a psychological intervention, researchers must compare the treatment condition with a control group that accounts for improvements caused by factors ...other than the treatment. Using an active control helps to control for the possibility that improvement by the experimental group resulted from a placebo effect. Although active control groups are superior to "no-contact" controls, only when the active control group has the same expectation of improvement as the experimental group can we attribute differential improvements to the potency of the treatment. Despite the need to match expectations between treatment and control groups, almost no psychological interventions do so. This failure to control for expectations is not a minor omission—it is a fundamental design flaw that potentially undermines any causal inference. We illustrate these principles with a detailed example from the video-game-training literature showing how the use of an active control group does not eliminate expectation differences. The problem permeates other interventions as well, including those targeting mental health, cognition, and educational achievement. Fortunately, measuring expectations and adopting alternative experimental designs makes it possible to control for placebo effects, thereby increasing confidence in the causal efficacy of psychological interventions.
Objective
Colorectal cancer survivors (CRCS) often experience high levels of distress. The objective of this randomized controlled trial was to evaluate the effect of blended cognitive behavior ...therapy (bCBT) on distress severity among distressed CRCS.
Methods
CRCS (targeted N = 160) with high distress (Distress Thermometer ≥5) between 6 months and 5 years post cancer treatment were randomly allocated (1:1 ratio) to receive bCBT, (14 weeks including five face‐to‐face, and three telephone sessions and access to interactive website), or care as usual (CAU). Participants completed questionnaires at baseline (T0), four (T1) and 7 months later (T2). Intervention participants completed bCBT between T0 and T1. The primary outcome analyzed in the intention‐to‐treat population was distress severity (Brief Symptom Inventory; BSI‐18) immediately post‐intervention (T1).
Results
84 participants were randomized to bCBT (n = 41) or CAU (n = 43). In intention‐to‐treat analysis, the intervention significantly reduced distress immediately post‐intervention (−3.86 points, 95% CI −7.00 to −0.73) and at 7 months post‐randomization (−3.88 points, 95% CI −6.95 to −0.80) for intervention compared to CAU. Among secondary outcomes, at both time points, depression symptoms, anxiety symptoms, cancer worry, and cancer‐specific distress were significantly lower in the intervention arm. Self‐efficacy scores were significantly higher. Overall treatment satisfaction was high (7.4/10, N = 36) and 94% of participants would recommend the intervention to other colorectal cancer patients.
Conclusions
The blended COloRectal canceR distrEss reduCTion intervention seems an efficacious psychological intervention to reduce distress severity in distressed CRCS. Yet uncertainty remains about effectiveness because fewer participants than targeted were included in this trial.
