Are different forms of repetitive negative thinking associated with interpretation bias in generalized anxiety disorder and depression?
Worry and rumination, two forms of repetitive negative thinking (RNT), are prevalent in generalized anxiety disorder (GAD) and depression. Cognitive processing biases, especially the tendency to draw negative conclusions from ambiguous information (interpretation bias), may maintain worry and rumination. Yet the relationship between interpretation bias and both forms of RNT has not been explored in clinical versus nonclinical samples. In this cross-sectional study, participants with GAD (n = 72), depression (n = 79), or neither disorder (n = 71) completed two tasks assessing interpretation bias, measures of worry and rumination, and reported negative thought intrusions during a behavioral task. Interpretation bias was associated with higher levels of worry, rumination, and negative thought intrusions. Both clinical groups generated significantly more negative interpretations than healthy comparison participants. These findings link interpretation bias to worry and rumination and establish the need for research investigating the causal role of interpretation bias in maintaining RNT

Measuring the longitudinal course of voice hearing under psychological interventions: a systematic review
Trials of psychological interventions targeting distressing voices have used a range of variables to measure outcomes. This has complicated attempts to compare outcomes across trials and to evaluate the effectiveness of these interventions. Therefore, this review aimed to identify the variables that have been used to measure the longitudinal course and impact of voice hearing under these interventions and to evaluate how these variables change over time. Inclusion and exclusion criteria were applied, resulting in a total of 66 articles. Of these, 60 studies (28 RCTs, 23 uncontrolled, 9 non-randomised) were published in peer-reviewed journals, whilst 6 were recently completed or currently ongoing. The findings of this review suggest that a range of variables that are not directly relevant to psychological interventions have been used (e.g., depression, characteristics of voice hearing experience), whilst those directly impacted by psychological interventions (e.g., voice-related distress), broader concepts of outcome (e.g., functioning) and specific associated processes (e.g., self-schema) have received less attention. Findings also showed that the majority of variables demonstrated improvements, but effect sizes varied considerably across trials. This may be attributed to methodological differences such as statistical power, blinding, control groups and different methods of measurement. Our review highlights the importance of determining a set of outcomes that are directly targeted and should change under psychological interventions. Recommendations include the use of voice-related distress as a primary outcome. This can ultimately facilitate comparisons across studies and inform the development of psychological interventions
Effects of modifying interpretation bias on transdiagnostic repetitive negative thinking.
Objective: Repetitive negative thinking (RNT; e.g., worry and rumination) is common across emotional disorders, as is the tendency to generate negative interpretations (interpretation bias). Ameliorating negative interpretations via cognitive bias modification of interpretations (CBM-I) reduces worry/rumination, and improves mood in people diagnosed with generalized anxiety disorder (GAD) or depression. We investigated whether these findings generalize to high worry or rumination populations, irrespective of diagnosis, and whether effects are increased by enhancing emotional engagement with training with active generation of positive resolutions of ambiguity and imagery. Method: Community volunteers with excessive worry and/or rumination, who were above clinical cut-off on anxiety and/or depression measures, were allocated to an active control condition (n = 54), interpretation training condition with prior activation of RNT (CBM_RNT; n = 54), or training condition augmented with positive outcome generation and imagery (CBM_ENH; n = 53). Interpretation bias, RNT, and mood were assessed before and following 10 Internet-based sessions completed within a 1-month period. RNT and mood questionnaires were also completed at 1-month follow-up. Results: After training, both forms of CBM-I (vs. control) facilitated more positive interpretations and reduced negative intrusions during a worry task. At 1-month follow-up, anxiety, depression, RNT, and worry in the past week were lower in the CBM-I than control conditions, but not rumination or trait worry. Compared with standard CBM-I, the augmented form facilitated more positive interpretations, reduced negative intrusions after training, and reduced trait rumination at 1-month follow-up, but it did not augment effects on trait worry, anxiety or depression. Conclusions: Interpretation bias maintains transdiagnostic RNT and Internet-based CBM-I can reduce longer-term RNT
Contrasting roles of histone 3 lysine 27 demethylases in acute lymphoblastic leukaemia
T-cell acute lymphoblastic leukaemia (T-ALL) is a haematological malignancy with a dismal overall prognosis, including a relapse rate of up to 25%, mainly because of the lack of non-cytotoxic targeted therapy options. Drugs that target the function of key epigenetic factors have been approved in the context of haematopoietic disorders, and mutations that affect chromatin modulators in a variety of leukaemias have recently been identified; however, âepigeneticâ drugs are not currently used for T-ALL treatment. Recently, we described that the polycomb repressive complex 2 (PRC2) has a tumour-suppressor role in T-ALL. Here we delineated the role of the histone 3 lysine 27 (H3K27) demethylases JMJD3 and UTX in T-ALL. We show that JMJD3 is essential for the initiation and maintenance of T-ALL, as it controls important oncogenic gene targets by modulating H3K27 methylation. By contrast, we found that UTX functions as a tumour suppressor and is frequently genetically inactivated in T-ALL. Moreover, we demonstrated that the small molecule inhibitor GSKJ4 (ref. 5) affects T-ALL growth, by targeting JMJD3 activity. These findings show that two proteins with a similar enzymatic function can have opposing roles in the context of the same disease, paving the way for treating haematopoietic malignancies with a new category of epigenetic inhibitors.National Institutes of Health (U.S.) (Grant R37-HD04502

Approaches to improving mental healthcare for autistic people: systematic review.
Autistic people have a high likelihood of developing mental health difficulties but a low chance of receiving effective mental healthcare. Therefore, there is a need to identify and examine strategies to improve mental healthcare for autistic people. To identify strategies that have been implemented to improve access, experiences of care and mental health outcomes for autistic adults, and to examine evidence on their acceptability, feasibility and effectiveness. A co-produced systematic review was conducted. MEDLINE, PsycINFO, CINHAL, medRxiv and PsyArXiv were searched. We included all study designs reporting acceptability or feasibility outcomes and empirical quantitative study designs reporting effectiveness outcomes. Data were synthesised using a narrative approach. A total of 30 articles were identified. These included 16 studies of adapted mental health interventions, eight studies of service improvements and six studies of bespoke mental health interventions developed for autistic people. There was no conclusive evidence on effectiveness. However, most bespoke and adapted approaches appeared to be feasible and acceptable. Identified adaptations appeared to be acceptable and feasible, including increasing knowledge and detection of autism, providing environmental adjustments and communication accommodations, accommodating individual differences and modifying the structure and content of interventions. Many identified strategies are feasible and acceptable, and can be readily implemented in services with the potential to make mental healthcare more suitable for autistic people, but important research gaps remain. Future research should address these and investigate a co-produced package of service improvement measures

Exploring service usersâ and practitionersâ priorities regarding outcomes of cognitive behavioural therapy for distressing voices: a thematic analysis
Background: The outcomes of Cognitive Behavioural Therapy for distressing voices and their measurement have mostly been determined by professionals, with little focus on the outcomes that matter to people who hear voices. The aim of this qualitative study was to explore views about the outcomes of Cognitive Behavioural Therapy for distressing voices from the perspectives of lived and professional experience. Methods: Fifteen service users and fourteen practitioners were recruited from mental health services. Semi-structured interview schedules were used to guide individual interviews with service users and focus groups with practitioners. All interviews were audio recorded and transcribed verbatim. Thematic analysis was applied to generate themes. Results: Four themes were identified: âI want what I canât haveâ, âFeeling empoweredâ, âUnderstanding and managing my emotionsâ, and âDoing more of what I want to doâ. Two themes contained sub-themes. Discussion: Valued outcomes by service users and practitioners appeared to reflect changes in voice characteristics, improvements in self-confidence and self-respect, acceptance of voices, understanding and managing emotions and personal outcomes. Findings suggest discrepancies between service usersâ and practitionersâ priorities in regard to changes in voice characteristics and understanding and managing negative emotions. Recommendations include a greater focus on managing emotions by practitioners.</p
Interpretation training to target repetitive negative thinking in generalized anxiety disorder and depression
OBJECTIVE:
Repetitive negative thinking (RNT) for example, worry in generalized anxiety disorder (GAD) and rumination in depression, is often targeted during psychological treatments. To test the hypothesis that negative interpretation bias contributes to worry and rumination, we assessed the effects of inducing more positive interpretations in reducing RNT.
METHOD:
Volunteers diagnosed with GAD (66) or depression (65) were randomly allocated to one of two versions of cognitive bias modification for interpretation (CBM-I), either with or without RNT priming prior to training, or a control condition, each involving 10 Internet-delivered sessions. Outcome measures of interpretation bias, a behavioral RNT task and self-reported worry, rumination, anxiety and depression were obtained at baseline, after home-based training and at 1-month follow-up (self-report questionnaires only).
RESULTS:
CBM-I training, across diagnostic groups, promoted a more positive interpretation bias and led to reductions in worry, rumination, and depressive symptoms, which were maintained at follow-up. Anxiety symptoms were reduced only in the GAD group at follow-up. There were no differences between CBM-I versions; brief priming of RNT did not influence CBM-I effectiveness. Level of interpretation bias post training partially mediated the effects of CBM-I on follow-up questionnaire scores.
CONCLUSIONS:
In contrast to some recent failures to demonstrate improvements following Internet-delivered CBM, we found that self-reported RNT and negative mood were reduced by CBM-I. This is consistent with a causal role for negative interpretation bias in both worry and rumination, suggesting a useful role for CBM-I within treatments for anxiety and depression.
