Effectiveness of Internet-Delivered Cognitive Behavioural Therapy (ICBT) in Improving Weight-Loss and Psychosocial Well-Being Among Adults With High BMI: A Systematic Review.

AIM: To examine the effectiveness of Internet-delivered Cognitive Behaviour Therapy (ICBT) in improving psychosocial well-being and promoting weight-loss in adults ≥ 18 years with BMI ≥ 25 kg/m2. BACKGROUND: Global obesity engenders significant physical and psychosocial health consequences. Second-wave ICBT focused on restructuring negative thoughts and behaviours has been explored as a potential intervention for elevated BMI and mental health concerns, but its effectiveness remains to be fully established, making further evaluation essential. METHODS AND DATA SOURCES: Eight databases were searched from inception to January 2025 for randomised controlled trials (RCTs), including participants ≥ 18 years with BMI ≥ 25 kg/m2 and second-wave ICBT evaluating BMI, weight, depression, eating behaviours, and self-esteem. This review followed PRISMA 2020. Study quality was assessed using the Cochrane Risk of Bias (ROB 2) and GRADE. Data were extracted using a modified Cochrane form. Random-effects meta-analysis calculated Standardised Mean Differences (SMD) with 95% confidence intervals, with subgroup analyses exploring heterogeneity. RESULTS: Nine trials with 2278 participants were included. Significant improvements were seen in BMI, weight, and depressive symptoms while self-esteem effects were small and non-significant. Compared with passive controls, ICBT showed greater improvements in BMI and weight, whereas differences versus active control were smaller and inconsistent. Face-to-face CBT demonstrated superior outcomes for depression and self-esteem. Male-tailored interventions showed greater improvements. Shorter programmes yielded larger short-term weight loss, while longer programmes supported more sustained effects. Narrative synthesis indicated improvements in emotional and external eating, with increased mindful and restrictive eating behaviours. CONCLUSION: ICBT improved weight, BMI, and depressive symptoms, with limited evidence for self-esteem. Male-tailored interventions and longer programmes may enhance sustainable outcomes. IMPACT: Future ICBT programs should integrate strategies targeting sustainable weight loss and psychosocial well-being to support long-term outcomes. NO PATIENT OR PUBLIC CONTRIBUTION: Patients or members of the public were not involved, as this study synthesised previously published data. TRIAL REGISTRATION: PROSPERO registration number: CRD42024497961.

Long-term efficacy of cognitive behavioural therapy for insomnia (CBT-I) on depressive symptoms: A systematic review and meta-analysis of randomised controlled trials.

Depressive symptoms are common in individuals with persistent insomnia. Previous meta-analyses of randomised controlled trials (RCTs) showed that cognitive behavioural therapy for insomnia (CBT-I) can reduce depressive symptoms at post-treatment. However, the long-term maintenance of these improvements has never been systematically examined. To fill-in this gap, we conducted a systematic review and meta-analysis of the long-term (≥3 months) effects of CBT-I on depressive symptoms. The review was registered in PROSPERO (CRD420251146061). Only RCTs in adults with insomnia were considered. Pubmed, Scopus, Psycinfo, CINAHL, and Medline were searched up to 12 September 2025 with no predefined time constraints. From 5359 records initially retrieved, we included 53 articles reporting on 13,608 individuals. After outliers removal, random effects meta-analysis showed that CBT-I was superior to control conditions in reducing depressive symptoms at 3 [k = 29, d = -.35, [95% CI: -.49 to -.21], p < .001], 6 [k = 29, d = -.32, [95% CI: -.59 to -.05], p = .018], and 12 [k = 10, d = -.25, [95% CI: -.39 to -.12], p < .001] months follow-ups. Results demonstrate that the effects of CBT-I on depressive symptoms are sustained throughout the year following treatment, although effects may decline over time.

Culturally adapted post-diagnostic dementia support for South Asian people living with dementia and caregivers: a rapid review.

BACKGROUND: The number of minority ethnic people living with dementia (PLWD) in the UK is predicted to rise to 50 000 by 2026 and 172 000 by 2051. As the global population ages, there is a greater need to develop culturally appropriate post-diagnostic support for PLWD from minority ethnic backgrounds. METHODS: A rapid review was conducted of culturally adapted post-diagnostic dementia support for South Asian people with dementia and carers. Eight electronic databases were searched from inception until 16 September 2025. Databases included Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica Database, MEDical Literature Analysis and Retrieval System Online, Psychological Information, Turning Research Into Practice, Allied and Complementary Medicine Database, Social Policy and Practice and the Cochrane Database of Systematic Reviews. Two reviewers independently screened the studies. Consistent with rapid review methods, no formal quality assessment of included studies was undertaken. The rapid review adhered to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. RESULTS: Twelve studies were included. These included seven carer support programmes focusing on raising awareness and education on dementia and care. These interventions increased carers' knowledge of dementia and confidence in caregiving. Four studies reported on psychosocial interventions: Cognitive Stimulation Therapy, Cognitive Behaviour Therapy and Meditation Therapy, demonstrating benefits for caregiver burden and mental health. One study reported on service-level innovations through a South Asian link nurse, which improved access to services and facilitated the development of culturally appropriate information materials. CONCLUSION: The findings of this rapid review demonstrate the feasibility and perceived value of culturally sensitive psychoeducation, carer training and psychosocial interventions. However, research remains small-scale, methodologically limited, with little focus given to interventions directly supporting PLWD.

Cognitive behavioural therapy-based interventions on stress outcomes in pregnant women: A systematic review and meta-analysis.

BACKGROUND: Stress symptoms were the most common psychological problem in pregnancy. Cognitive behavioural therapy-based interventions are effective for antenatal depression and anxiety symptoms; but there are fewer studies for stress symptoms. OBJECTIVE: The review aims to (1) examine the effectiveness of cognitive behavioural therapy-based interventions in reducing stress outcomes (pregnancy-specific stress symptoms, generic symptoms, and objective stress) in pregnant women, and (2) identify significant moderators affecting the effectiveness of the intervention. DESIGN: Systematic review, meta-analysis, and meta-regression analysis of randomised controlled trials. METHODS: We conducted a three-step search (12 databases, 4 clinical registries, and citation searches) in English and Chinese up to July 24, 2025, by two independent reviewers. Meta-analysis, subgroup, and meta-regression analyses were performed using the R software. Quality assessment and certainty of the evidence were assessed with the Cochrane risk-of-bias tool version 2 and Grading of Recommendations, Assessment, Development, and Evaluation criteria. Publication bias was assessed using funnel plots and Egger's test. RESULTS: We included 20 randomised controlled trials involving a total of 6966 pregnant women from nine countries. Random-effects meta-analyses found that interventions significantly alleviated pregnancy-specific stress symptoms (Hedges' g = -0.84, 95% Confidence Interval, CI -1.42, -0.26, p < .01, I2 = 92.3%), reduced generic stress symptoms (g = -0.64, 95% CI -1.09, -0.20, p < .01, I2 = 87.4%) with median and large effect sizes at post-intervention. No effect was found in lowering cortisol levels (g = -0.99, 95% CI -2.58, -0.60, p = .12, I2 = 84%) at post-intervention. Subgroup and meta-regression analyses indicated that region, age of participants, use of intention-to-treat, missing data management analyses, frequency, modalities, and approaches of interventions, use of different comparators, and attrition rate were significant factors affecting the effectiveness of interventions. Subgroup analyses suggested that the intensity of intervention should be more than once per week using a blended mode among Asian populations. Multivariate meta-regression analyses indicated that both younger age (β = 0.13, p = .02) and a lower attrition rate (β = 0.03, p = .03) significantly improved the effectiveness of interventions. The overall certainty of the evidence was rated as either very low or low. CONCLUSIONS: Cognitive behavioural therapy-based interventions can supplement antenatal care to alleviate pregnancy-specific stress symptoms and generic stress symptoms, particularly in young Asian women. However, the evidence has some uncertainties. These findings should be interpreted with caution due to substantial heterogeneity. Well-designed trials on a large-scale with long-term follow-ups were needed. REGISTRATION: PROSPERO registration ID: CRD420251115913.

Five-year outcomes in a randomised controlled trial of prolonged exposure therapy and supportive counselling for post-traumatic stress disorder in adolescents: a task-shifted intervention.

BACKGROUND: Cognitive-behavioural therapies with a trauma focus are effective in reducing posttraumatic stress disorder and other psychological distress in adolescents. Long-term follow-up data on adolescents treated for PTSD remain scarce, with few studies extending beyond 12 months after treatment completion. OBJECTIVE: To evaluate the maintenance of treatment gains in a comparative study of effectiveness of PE-A and SC up to 60 months post-treatment. METHOD: Sixty-three adolescents diagnosed with PTSD were randomly assigned to either treatment, provided by newly trained and supervised non-specialist health workers. The primary outcome measure was PTSD symptom severity, as independently assessed on the Child PTSD Symptom Scale (CPSS). We report on the 60-month post-treatment follow-up, building on post-treatment, 3-month, 6-month, 12-month and 24-month post-treatment data that have been published previously. RESULTS: Participants in both treatment groups maintained a significant reduction in PTSD symptoms up to 60-months post-treatment (F (7, 343) = 2.86, p < .01). Participants receiving prolonged exposure experienced greater improvement on the CPSS at all follow-up assessment timepoints, except for the 60-month FU (p = .28; g = 0.33). CONCLUSION: Adolescents with PTSD continued to maintain treatment gains up to 60-months post-treatment. These data, along with findings from the original RCT, indicate that a brief treatment protocol (averaging 9 sessions of PE-A or SC) in a LMIC, task-shifted to be delivered by nurses without prior psychotherapy experience, led to lasting improvements in PTSD and comorbid symptoms for up to five years. The sustained benefits and improved functioning over the first few years post-treatment support expanding both treatments, especially PE-A, in community settings.

Psychological interventions for individuals affected by Huntington's disease: effects on depression, anxiety, and emotional well-being.

INTRODUCTION: The literature provides limited evidence on the effectiveness of psychological interventions for individuals living with Huntington's Disease (HD). This study aims to examine the role of psychological support in improving the well-being of individuals and families affected by HD. METHODS: The study methodology builds on previous work conducted by the European Huntington Association (EHA). The study includes individuals across three categories: individuals at risk of HD, premanifest HD, or with an HD-negative genetic test. Eligible participants were offered eight online individual cognitive behavioural therapy (CBT) sessions followed by two group sessions. Assessments were performed at pre-intervention, after the individual sessions and after the group sessions. The primary outcomes were anxiety, depression, positive and negative affect, and quality of life. RESULTS: Twenty-one individuals participated in the study, of whom 33% (n = 7) had an HD-negative genetic test, 29% (n = 6) were at risk, and 38% (n = 8) had premanifest HD; the cohort was 57% women (n = 12). Analyses showed significant reductions in depression and anxiety, with medium to large effect sizes. Negative affect also decreased significantly with a large effect, while positive affect showed a non-significant trend toward improvement. Quality-of-life outcomes (physical and mental health components) did not change significantly. Overall, the strongest effects were observed for mood-related outcomes (depression, anxiety, and negative affect). CONCLUSION: Our data shows that a short-term CBT intervention led to improvements in anxiety, depression and negative affect. These findings enhance the evidence base available supporting the efficacy of psychological interventions that may be beneficial for individuals affected by HD. The article also outlines key lessons regarding intervention tailoring and study design to inform future research exploring the efficacy of psychological interventions for this population.

Psychological interventions to improve maternal mental health and resilience during pregnancy in the COVID-19 pandemic: a systematic review.

BACKGROUND: During the COVID-19 pandemic, pregnant women experienced increased psychological distress, while access to routine mental health care was often disrupted. Psychological interventions may provide an effective strategy to support maternal mental health under these circumstances. OBJECTIVE: This systematic review aimed to provide an overview of psychological interventions for pregnant women during the COVID-19 pandemic and to evaluate their effectiveness in reducing distress and enhancing resilience. METHODS: A systematic search of four databases was conducted up to 3 September 2025. Randomised and non-randomised studies evaluating psychological interventions during pregnancy were included. RESULTS: Sixteen studies met the inclusion criteria. Interventions included cognitive behavioural therapy, mindfulness-based interventions, psychoeducation, and other psychological approaches delivered through individual, group, digital, or hybrid formats. Most studies reported reductions in depression, anxiety, or stress, and some found improvements in resilience-related factors. However, the methodological quality was modest; with heterogeneous outcome measures and limited follow-up. CONCLUSIONS: Overall, psychological interventions adapted for digital or hybrid delivery show promise for improving maternal emotional well-being in times of crises. The findings suggest that accessible and scalable psychological interventions may support maternal mental health during crisis situations when routine care is disrupted. Future research should prioritize larger, methodologically rigorous trials with standardized outcomes, and longer follow-up periods.

Feasibility and effectiveness of the Bergen 4-Day Treatment for obsessive-compulsive disorder in Australia: A pilot comparison with 3-week inpatient obsessive-compulsive disorder treatment.

OBJECTIVES: Obsessive-compulsive disorder is a debilitating and chronic condition that, when untreated or unresponsive to treatment, imposes a significant health and economic burden on individuals and families. This prospective non-randomised inpatient study compared the acceptability and clinical outcomes of the Bergen 4-Day Treatment programme with those of a standard 3-week specialised treatment programme for obsessive-compulsive disorder in Australia. METHOD: Twenty-five participants diagnosed with obsessive-compulsive disorder were non-randomly assigned to Bergen 4-Day Treatment (n = 12) or a 3-week standard (n = 13) inpatient programme. Independent assessments were completed at pre-treatment, 10 days post treatment and at 3-month follow-up. The Yale-Brown Obsessive-Compulsive Scale was rated to assess obsessive-compulsive disorder severity, while secondary measures of depression, anxiety, obsessive beliefs and wellbeing were self-rated by participants. RESULTS: Baseline characteristics of both groups were comparable, with obsessive-compulsive disorder symptom severity within the moderate to severe range. After treatment, obsessive-compulsive disorder symptoms as well as secondary depression and anxiety symptoms were reduced in both treatment groups. Participants receiving Bergen 4-Day Treatment had significantly lower Yale-Brown Obsessive-Compulsive Scale scores at 10 days (M = 13.46) and 3 months (M = 11.84), compared to standard treatment (M = 19.04 and M = 19.15, respectively). Response (91.9%) and remission (45.8%) rates for the Bergen 4-Day Treatment group were significantly higher at both post-treatment timepoints, compared to the standard treatment group. No dropouts occurred in the Bergen 4-Day Treatment group, and participant satisfaction was high. CONCLUSION: The findings of this pilot open-label study suggest that Bergen 4-Day Treatment shows promise as an acceptable, efficient and effective treatment for obsessive-compulsive disorder, warranting further investigation as a scalable alternative for improving access to specialised obsessive-compulsive disorder treatment in Australia.

Preferences for behavioural, analytic and gestalt psychotherapy.

This study investigated preferences for behavioural, analytic and gestalt psychotherapy among a sample of 40 SES class III and IV adult females and 67 college freshmen who had never been actual therapy patients. A scaled survey assessed general preference, preference given an imagined long-standing depressive disorder, preference given an imagined specific phobia, and preference for the therapist-patient relationship. Three audio tapes were designed, each describing one of the modalities. High inter-rater reliability and agreement were determined by three independent judges. Results showed that young females had a general preference for gestalt therapy. Young and old females, but not young males, significantly preferred behavioural therapy for a specific phobia. Under forced-choice conditions the group as a whole significantly preferred gestalt therapy. No differences were found for the relationship or preference given a depressive disorder. Preference was hypothesized as a cognitive structure with potential use in therapist-client matching.

Reality orientation and staff attention: a controlled study.

A trial was carried out of Reality Orientation (R.O.) in a residential home for the elderly mentally infirm with a 'social therapy' control group, receiving the same amount of staff attention as the R.O. group, in addition to an untreated control group. R.O. residents improved more on tests of information and orientation and various aspects of memory than controls. These results support the hypothesis that the nature of staff attention is crucial and that it should encourage and reward appropriate behaviour. No differential effects of treatment were found on rating scale assessments of the resident's functioning in the home.

The new frontier in understanding human and mammalian brain development.

Neurodevelopmental disorders that cause cognitive, behavioural or motor impairments affect around 15% of children and adolescents worldwide1, with diagnoses of profound autism and attention deficit hyperactivity disorder increasing in the USA and contributing to a major economic burden2,3. Yet the origins and mechanisms of these conditions remain poorly understood, limiting progress in therapies. Comprehensive cell atlases of the developing human brain, alongside those of model organisms such as mice and non-human primates, are now providing high-resolution measures of gene expression, cell-type abundance and spatial distribution. In this Perspective, we highlight recent studies that have identified novel developmental cell populations, revealed conserved and divergent patterns of cell genesis, migration and maturation across species, and begun testing hypotheses that link them to processes ranging from transcriptional control of cell fate specification to the emergence of complex behaviours. We present remaining conceptual and technical challenges and provide an outlook on how further studies of human and mammalian brain development can empower a deeper understanding of neurodevelopmental and neuropsychiatric disorders. Future efforts expanding to additional developmental stages, including adolescence, as well as whole-brain, multimodal and cross-species integration, will yield new insights into how development shapes the brain. These atlases promise to serve as essential references for unravelling mechanisms of brain function and disease vulnerability, and for advancing precision medicine.

Personality, expectancies and group psychotherapy.

The paper reports an extension of work into the relevance of personality and pre-treatment expectancies for allocation and response of patients to group psychotherapy. The results show that subjects who are internally directed in interest and who have a liberal attitude to a variety of social issues and a "psychological" set to treatment are more responsive to group psychotherapy as seen by their therapists as well as by themselves. Those who are externally directed in interest and who have a conservative attitude to life and a more "medical-physical" set to treatment are more likely to be referred for behaviour therapy; if referred for group psychotherapy they are likely either to drop out or to show very limited response to treatment.

Late-onset epileptic spasms: presentation, aetiology and outcome.

Late-onset epileptic spasms (LOES) are epileptic spasms (ES) commencing after age 12 months, often misdiagnosed and having uncertain relationship to infantile spasms. Previous studies of mostly small LOES cohorts frequently reported 'cryptogenic' aetiologies. We studied the presentations, aetiologies, treatment responses and outcomes in a large LOES cohort, evaluated with modern neuroimaging and genomic testing. In this retrospective cohort study, 62 children with video-confirmed epileptic spasms, diagnosed between 2011 and 2021, were included. All had epileptiform activity on EEG, but none had hypsarrhythmia. Median age at epileptic spasms onset was 23 months (range 1-15 years) and median delay to diagnosis was 8 months (interquartile range: 3-15). Only 24% children were correctly diagnosed at presentation, common misdiagnoses being myoclonic epilepsies and non-epileptic phenomenon. Aetiology was identified in 95%. Structural-malformative aetiologies were present in 63% (most commonly focal cortical dysplasia and mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy). Other aetiologies were structural-acquired in 13% (mostly postnatal stroke and CNS infections), genetic in 13% (mostly intragenic variants and chromosomopathies) and oncological in 6% (history of leukaemia, two with CNS involvement). Children with structural aetiologies often had normal development prior to onset of epileptic spasms, a later median age of epileptic spasms onset and were more likely to have asymmetric or subtle epileptic spasms and additional seizures prior to epileptic spasms. Epileptic spasms ceased in 29% children treated with prednisolone, most having genetic aetiologies and in 35% treated with vigabatrin, all having structural-malformative aetiologies. Apart from clobazam, which was effective in 17% of children, all other antiseizure medications, vagus nerve stimulation and ketogenic diet therapy were ineffective. Epileptic spasms ceased in 86% (18/21) of children who underwent epilepsy surgery. At median follow-up of 10.3 years, 53% children were free of all seizures and 76% were free of epileptic spasms. More children with unilateral structural-malformative aetiologies achieved seizure freedom than other aetiologies, most commonly following surgery but occasionally following treatment with vigabatrin or clobazam. Impairment of cognitive function or adaptive behaviour (formally assessed in 90%) was significantly more common in children with genetic than structural aetiologies, and in children with ongoing seizures than seizure freedom. Among children who underwent epilepsy surgery, 62% achieved average or low-average adaptive functioning or normal intellectual capacity. This study highlights the importance of prompt recognition of epileptic spasms in older children for improved seizure and developmental outcomes. Brain malformations and insults are the predominant causes of LOES, and when unilateral, respond best to epilepsy surgery.

Acute confusional states and depression treated with maprotiline mesylate. Report of 4 patients successfully treated in an intensive care unit.

Four patients admitted to hospital with multiple injuries developed psychiatric symptoms after an initially favourable response to intensive therapy. Alterations in the level of consciousness and behavioural pattern were observed, associated with the presence of acute depression, possibly endogenous in origin. Within 24--48 hours of intravenous administration of maprotiline mesylate (Ludiomil, Ciba), a tetracyclic antidepressant drug, considerable improvement was noted in all 4 patients, with regard to both the depressive state and the clouding of consciousness. The importance of recognizing psychiatric disorders in severely ill patients in an intensive therapy environment is stressed.
