In a baseline study among 7- and 8-year-old children with auditory vocal hallucinations, only limited functional impact was observed.
To assess 5-year course and predictors of auditory vocal ...hallucinations, as well as 5-year incidence and its risk factors.
A sample of 337 children, 12 and 13 years of age, were reassessed on auditory vocal hallucinations and associated symptoms after a mean follow-up period of 5.1 years.
The 5-year persistence and incidence rates were 24% and 9% respectively, with more new cases arising in urban areas.Both persistent and incident auditory vocal hallucinations were associated with problem behaviour in the clinical range of psychopathology as measured with the Child Behavior Checklist, particularly at follow-up, as well as with other psychotic symptoms, particularly at baseline. Persistence was predicted by baseline auditory vocal hallucinations severity,particularly in terms of external attribution of voices and hearing multiple voices, and was associated with worse primary school test scores and lower secondary school level.
First onset of auditory vocal hallucinations in middle childhood is not uncommon and is associated with psychopathological and behavioural comorbidity. Similarly,persistence of auditory vocal hallucinations in childhood is not uncommon and is associated with psychopathological,behavioural and cognitive alterations.
Objectives
The need for a brief screening tool for psychosis is widely recognized. The Community Assessment of Psychic Experiences (CAPE) is a popular self‐report measure of psychosis, but a cut‐off ...score that can detect those most likely to fulfill diagnostic criteria for psychotic disorder is not established.
Methods
A case–control sample from the Genetic Risk and Outcome of Psychosis Project study (N = 1375, healthy individuals, n = 507, and individuals with a psychotic disorder, n = 868), was used to examine cut‐off scores of the CAPE with receiver operating curve analyses. We examined 27 possible cut‐off scores computed from a combination of scores from the frequency and distress scales of the various factors of the CAPE.
Results
The weighted severity positive symptom dimension was most optimal in detecting individuals with a psychotic disorder (>1.75 cut‐off; area under the curve = 0.88; sensitivity, 75%; specificity, 88%), which correctly identified 80% of the sample as cases or controls with a diagnostic odds ratio of 22.69.
Conclusions
The CAPE can be used as a first screening tool to detect individuals who are likely to fulfill criteria for a psychotic disorder. The >1.75 cut‐off of the weighted severity positive symptom dimension provides a better prediction than all alternatives tested so far.

The aim of this study was to systematically investigate the effectiveness of hatha yoga in treating acute, chronic and/or treatment-resistant mood and anxiety disorders.
Medline, Cochrane Library, ...Current Controlled Trials, Clinical Trials.gov, NHR Centre for Reviews and Dissemination, PsycINFO and CINAHL were searched through June 2018. Randomized controlled trials with patients with mood and anxiety disorders were included. Main outcomes were continuous measures of severity of mood and anxiety symptoms. Cohen's d was calculated as a measure of effect size. Meta-analyses using a random effects model was applied to estimate direct comparisons between yoga and control conditions for depression and anxiety outcomes. Publication bias was visually inspected using funnel plots.
Eighteen studies were found, fourteen in acute patients and four in chronic patients. Most studies were of low quality. For depression outcomes, hatha yoga did not show a significant effect when compared to treatment as usual, an overall effect size of Cohen's d -0.64 (95% CI = -1.41, 0.13) or to all active control groups, Cohen's d -0.13 (95% CI = -0.49, 0.22). A sub-analysis showed that yoga had a significant effect on the reduction of depression compared to psychoeducation control groups, Cohen's d -0.52 (95% CI = -0.96, -0.08) but not to other active control groups, Cohen's d 0.28 (95% CI = -0.07, 0.63) For studies using a follow-up of six months or more, hatha yoga had no effect on the reduction of depression compared to active control groups, Cohen's d -0.14 (95% CI = -0.60, 0.33). Regarding anxiety, hatha yoga had no significant effect when compared to active control groups, Cohen's d -0.09 (95% CI = -0.47, 0.30). The I2 and Q-statistic revealed heterogeneity amongst comparisons. Qualitative analyses suggest some promise of hatha yoga for chronic populations.
The ability to draw firm conclusions is limited by the notable heterogeneity and low quality of most of the included studies. With this caveat in mind, the results of the current meta-analysis suggest that hatha yoga does not have effects on acute, chronic and/or treatment-resistant mood and anxiety disorders compared to treatment as usual or active control groups. However, when compared to psychoeducation, hatha yoga showed more reductions in depression. It is clear that more high-quality studies are needed to advance the field.

Abstract
Hallucinations in children and adolescents are now known to occur on a continuum from healthy to psychopathology-related phenomena. Although hallucinations in young populations are mostly ...transient, they can cause substantial distress. Despite hallucinations being widely investigated, research so far has had limited implications for clinical practice. The present article has 3 main aims: (1) to review research findings since 2014 (when the last major review of the area was published); (2) to present assessment tools validated to measure hallucinations in children and adolescents; and (3) to discuss therapeutic strategies and clinical issues. We conclude by presenting a tailored care model for clinicians and outline future challenges for research.
Our ability to accurately predict development and outcome of early expression of psychosis is limited. To elucidate the mechanisms underlying psychopathology, a broader, transdiagnostic approach that ...acknowledges the complexity of mental illness is required. The upcoming network paradigm may be fruitful here. In this study, we applied a transdiagnostic network approach to psychosis. Data pertain to the third wave (second follow-up) of a sample of adolescents originally recruited at age 7-8 years. At baseline, N = 347 children with auditory verbal hallucinations (AVH) and N = 347 control children were included. N = 293 of these N = 694 children participated in the second follow-up (mean age 18.9 years; 59% women). Participants completed the Community Assessment of Psychic Experiences (CAPE) and the Depression, Anxiety and Stress Scale (DASS-21). A specific type of network model, the Ising model, was applied to dichotomized CAPE and DASS items. Interconnections of experiences within the same domain were observed, as well as interconnections between experiences of multiple domains of psychopathology. Quantitative and qualitative differences in network architecture were found in networks of psychopathological experiences in individuals with or without AVH at age 7-8 years. Although adolescents with or without previous AVH did not differ in their current CAPE scores, differences in the interconnectedness of psychopathology items were still found, possibly mirroring a difference in psychosis liability. This study showed that it is possible to map transdiagnostic experiences of psychopathology as a network and that important information can be derived from this approach in comparison to regular approaches.
Objective: To examine the added value of a 9-week mindful yoga intervention (MYI) as add-on to treatment as usual (TAU) in reducing depression for young women (18-34 years) with major depressive ...disorder (MDD). Method: Randomized controlled trial (RCT; n = 171) comparing TAU + MYI with TAU-only. Assessments were at baseline, postintervention, and at 6- and 12-month follow-up. Primary outcome measures were clinician-rated and self-reported symptoms of depression, together with a diagnostic interview to establish MDD diagnosis that was restricted to the baseline and 12-month follow-up assessments. Quality of life in various domains was assessed as secondary outcome measure. As potential mediators for treatment efficacy, we included self-report measures of rumination, self-criticism, self-compassion, intolerance of uncertainty, perceived body awareness and dispositional mindfulness, together with behavioral measures of attentional bias (AB) and depression-related self-associations. Results: Adding MYI to TAU did not lead to greater reduction of depression symptoms, lower rate of MDD diagnosis or increase in quality of life in various domains of functioning at post and follow-up assessments. There were no indirect effects through any of the potential mediators, with the exception of self-compassion. Conclusion: Adding MYI to TAU appeared not more efficacious than TAU-only in reducing depression symptoms in young women.
What is the public health significance of this article?
Overall, this study suggests that adding a mindful yoga intervention to treatment as usual for young women with depression does not lead to increased benefits in terms of stronger reduction in symptoms of depression, lower rate of major depressive disorder diagnosis, or better quality of life within various domains of functioning.

Typically reported as vivid, multisensory experiences which may spontaneously resolve, hallucinations are present at high rates during childhood. The risk of associated psychopathology is a major ...cause of concern. On the one hand, the risk of developing further delusional ideation has been shown to be reduced by better theory of mind skills. On the other hand, ideas of reference, passivity phenomena, and misidentification syndrome have been shown to increase the risk of self-injury or heteroaggressive behaviors. Cognitive psychology and brain-imaging studies have advanced our knowledge of the mechanisms underlying these early-onset hallucinations. Notably, specific functional impairments have been associated with certain phenomenological characteristics of hallucinations in youths, including intrusiveness and the sense of reality. In this review, we provide an update of associated epidemiological and phenomenological factors (including sociocultural context, social adversity, and genetics, considered in relation to the psychosis continuum hypothesis), cognitive models, and neurophysiological findings concerning hallucinations in children and adolescents. Key issues that have interfered with progress are considered and recommendations for future studies are provided.
Background
Bullying and poor theory of mind (ToM) are both considered to negatively impact academic performance. However, it is unclear if they have separate effects.
Aim
The aim of the current study ...was to examine the potentially separate associations of bullying and ToM with academic performance.
Sample
A general population sample of 1,170 children aged 11–12 years.
Methods
Information on bullying, type of involvement (none, victim (only), bully (only), victim–bully (both)), ToM, and estimated intelligence was obtained at face‐to‐face assessments. Information on academic performance was obtained from Danish school registers.
Results
ToM was positively associated with academic performance, and involvement in bullying was negatively associated with academic performance. Academic performance differed between types of involvement in bullying. Pairwise post hoc analyses showed that in the full sample, the only significant difference was between those not involved and those involved as victim (only). This was also the case for girls. Adjusting for potential shared variance with gender, estimated intelligence and ToM being victim (only) and victim–bully (both) were negatively associated with academic performance compared to no involvement. Thus, being a victim (or victim–bully) contributes negatively to academic performance beyond the effects of ToM and intelligence, and regardless of gender. Similarly, ToM remained positively associated with academic performance after adjusting for shared variance.
Conclusion
ToM and involvement in bullying were both separately associated with later academic performance. These results remained even after adjusting for shared variance, and for shared variance with gender and estimated IQ.

Alterations in Theory-of-Mind (ToM) are associated with psychotic disorder. In addition, studies in children have documented that alterations in ToM are associated with Psychotic Experiences (PE). ...Our aim was to examine associations between an exaggerated type of ToM (HyperToM) and PE in children. Children with this type of alteration in ToM infer mental states when none are obviously suggested, and predict behaviour on the basis of these erroneous beliefs. Individuals with HyperToM do not appear to have a conceptual deficit (i.e. lack of representational abilities), but rather they apply their theory of the minds of others in an incorrect or biased way.
Hypotheses were tested in two studies with two independent samples: (i) a general population sample of 1630 Danish children aged 11-12 years, (ii) a population-based sample of 259 Dutch children aged 12-13 years, pertaining to a case-control sampling frame of children with auditory verbal hallucinations. Multinomial regression analyses were carried out to investigate the associations between PE and ToM and HyperToM respectively. Analyses were adjusted for gender and proxy measures of general intelligence.
Low ToM score was significantly associated with PE in sample I (OR = 1.6 95%CI 1.1-2.3 χ2(4) = 12.42 p = 0.010), but not in sample II (OR = 0.9 95%CI 0.5-1.8 χ2(3) = 7.13 p = 0.816). HyperToM was significantly associated with PE both in sample I (OR = 1.8, 95%CI 1.2-2.7 χ2(3) = 10.11 p = 0.006) and II (OR = 4.6, 95%CI 1.3-16.2 χ2(2) = 7.56 p = 0.018). HyperToM was associated particularly with paranoid delusions in both sample I (OR = 2.0, 95%CI: 1.1-3.7% χ2(4) = 9.93 p = 0.021) and II (OR = 6.2 95%CI: 1.7-23.6% χ2(4) = 9.90 p = 0.044).
Specific alterations in ToM may be associated with specific types of psychotic experiences. HyperToM may index risk for developing psychosis and paranoid delusions in particular.

Objectives
Despite the gains made by current first‐line interventions for major depressive disorder (MDD), modest rates of treatment response and high relapse indicate the need to augment existing ...interventions. Following theory and initial research indicating the promise of mindful yoga interventions (MYIs), this study examines mindful yoga as a treatment of MDD.
Methods/Design
This randomized controlled trial uses a sample of young females (18–34 years) to examine the efficacy and cost‐effectiveness of a 9‐week manualized MYI added to treatment as usual (TAU) versus TAU alone. Primary outcome measures consist of clinician‐administered (Hamilton Depression Rating Scale) and self‐report (Depression‐Anxiety‐Stress Scales) measures of depression. Underlying mechanisms will be examined, including rumination, negative self‐evaluation, intolerance of uncertainty, interoceptive awareness, and dispositional mindfulness. Assessments were conducted at preintervention and will be conducted at postintervention, 6‐, and 12‐month follow up.
Results
The baseline sample consists of 171 females (88 were randomized into the MYI), reporting a baseline Mage = 25.08 years (SDage = 4.64), MHamilton‐depression = 18.39 (SDHamilton = 6.00), and a MDASS‐depression = 21.02 (SDDASS = 9.36).
Conclusion
This trial will provide important information regarding the benefits of adding yoga‐based interventions to TAU for young women with MDD and the mechanisms through which such benefits may occur.
