Children displaced by armed conflict are at high risk of experiencing psychological distress. The ongoing war in Gaza has resulted in widespread trauma among Palestinian youth, yet limited data exist on their mental health following displacement. This study assessed the prevalence and correlates of anxiety and depressive symptoms among war-displaced Palestinian refugee children and adolescents resettled in Qatar.
Aims
To estimate the prevalence of clinically significant anxiety and depressive symptoms and to identify psychosocial and trauma-related factors associated with symptom severity in this population.
Method
A cross-sectional study was conducted among 350 Palestinian children (aged 8–17 years) residing in a residential compound in Qatar. Symptoms of anxiety and depression were measured using the Screen for Child Anxiety Related Emotional Disorders-Child Version and the Short Mood and Feelings Questionnaire-Child Version, respectively. A Resilience and Demographic Questionnaire was devised to assess trauma exposure and psychosocial variables. Multiple linear regression identified factors associated with symptom severity.
Results
Clinically significant anxiety and depressive symptoms were found in 70.9 and 46.0% of participants, respectively. Separation anxiety was the most common subtype. Female gender, witnessing death, physical injury and disrupted caregiving were significantly associated with worse outcomes.
Conclusions
This study highlights the urgent need for trauma-informed, culturally sensitive mental health services for displaced Palestinian children and young people. While clinical interventions are vital, a sustainable resolution to the conflict is essential to mitigate further psychological harm.
Schizophrenia (SZ), bipolar disorder (BD), and depressive disorder (DEP) are disabling diseases influenced by genetic and environmental factors. Several risk factors have been identified for these disorders in various systematic reviews, meta-analyses, and umbrella reviews. Identifying risk factors for these disorders is essential to be able to target disorder-specific or transdiagnostic interventions. We aimed to systematically review existing meta-analyses on selected risk factors for SZ, BD, and DEP. We systematically searched for meta-analyses of risk factors relating to pregnancy and birth, childhood and adolescence, lifestyle, somatic conditions, infectious agents, and environmental exposures published since 2000. The transdiagnostic comparison included 70 meta-analyses, encompassing results for 55 risk factors that were studied across at least two of the three disorders. In our extensive transdiagnostic umbrella, 74% of reported effect sizes for the risk factors from meta-analyses were statistically significant. Childhood maltreatment was a robust transdiagnostic risk factor for all three disorders. We also found differences in risk factors, for example, pregnancy and birth complications associated strongly with SZ risk, and several somatic conditions were associated with DEP. It should be noted that many meta-analyses were low quality and based on a small number of original studies. More high-quality longitudinal research is needed on many risk factors to be able to evaluate their validity in single outcomes and their potential specificity or non-specificity.
Non-suicidal self-injury (NSSI) displays an alarmingly high prevalence rate among university students, placing them at high risk for adverse long-term outcomes, including suicide.
Aims
This study aimed to achieve a better understanding of factors contributing to NSSI in university student populations by examining reasons for NSSI and histories of stressful events and coping strategies.
Method
A total of 185 university students with a lifetime history of NSSI were assessed for depressive symptoms and NSSI characteristics. They completed three questionnaires on NSSI reasons, stressful events and coping strategies during childhood and adolescence. Each questionnaire included an ‘others’ option combined with an open-ended response box. After descriptive analysis of the closed questions, these open-ended responses were qualitatively categorised and analysed as predictors of depression severity and NSSI continuation from adolescence into adulthood.
Results
Qualitative analysis identified eight, five and ten categories from the open-ended responses for NSSI reasons, stressful events and coping strategies, respectively, with substantial to almost perfect interrater reliability. Two qualitative reason categories, one stressful event category and two coping strategy categories significantly predicted depression severity (β = 0.21–0.23). Participants reporting events in the stressful events category ‘Traumatisation and experiences of violence’ were three times more likely to continue NSSI into adulthood (f2 = 0.07).
Conclusions
This study demonstrates the value of mixed-methods approaches. Stable qualitative categories highlight the need to capture individual variations in NSSI-related factors. It emphasises trauma-related stressors due to their influence on depression severity and persistence of NSSI into adulthood.
Breast cancer is the most commonly diagnosed cancer worldwide. An estimated 1 in 7 women in the UK will receive a diagnosis during their lifetime, and up to 20% of people with breast cancer are treated with selective serotonin reuptake inhibitors (SSRIs). This comorbidity is a particularly important consideration for those co-prescribed hormonal cancer treatments. This article explores the complex relationship between breast cancer and mental illness, examining associations between hormonal breast cancer treatments, the premature menopause they can induce and SSRIs. It addresses prescribing considerations in this population, focusing on the co-prescribing of endocrine treatments such as tamoxifen and aromatase inhibitors with SSRIs and other psychotropic medications.
Various key events characterise experiences in later life, such as retirement, bereavement, caregiving, developing long-term conditions and hospital admission. Given their potential to disrupt lives, such events may affect older people’s mental health, but research on the associations between such events and depression has produced inconsistent findings.
Aims
To investigate the impact of key events in later life on depression trajectories in a representative cohort of people aged 50–69 in England.
Method
Our sample draws on 6890 respondents aged 50–69 in Wave 1 (2002/2003) of the English Longitudinal Study of Ageing, following them through to Wave 9 (2018/2019). We measured depression using the eight-item Center for Epidemiological Studies Depression scale. Later life events included retirement, spouse/partner death, becoming an unpaid caregiver, developing a limiting long-term illness and hospital admissions because of a fall or non-fall causes. Piecewise mixed-effects logistic regression models tested for changes in the trajectories of depression before and after each event.
Results
Statistically significant improvements in the trajectory of depression were observed following spousal bereavement, one’s own retirement and hospital admission because of causes other than falls, with reductions in the odds of depression of 48% (odds ratio: 0.52 (95% CI: 0.44–0.61)), 15% (0.85 (0.78–0.92)) and 4% (0.96 (0.94–0.99)), respectively. No changes were associated with developing a limiting long-term illness, becoming an unpaid caregiver or following spousal retirement or a hospital admission because of a fall.
Conclusions
The findings highlight the relative resilience among older adults in England in terms of depression following key later life events. There is still a role to play in delivering mental health support for older people following such events, particularly by improving the identification of those at risk of certain events as part of a broader strategy of prevention. Findings also underscore the importance of partner/spousal circumstances on individual mental health.
Depression is the most common psychiatric disorder among patients with end-stage renal disease (ESRD), yet the risk factors for mortality in this population remain unclear.
Aims
To identify risk factors for mortality in ESRD patients with depression and assess the incidence of suicide attempts.
Method
We used Taiwan’s National Health Insurance Research Database to identify adult patients who initiated maintenance dialysis between 1997 and 2012. Two ESRD cohorts were established at a depression-to-non-depression ratio of 1:8, matched by age and gender (n = 3289 with depression; n = 26 312 without depression). Outcomes included all-cause mortality and suicide attempts, with additional subgroup analyses by baseline depression severity.
Results
ESRD patients with depression had a higher mortality risk (hazard ratio 1.15, 95% CI: 1.10–1.21) than those without. Risk factors for mortality included male gender, older age, diabetes and cardiovascular disease. Patients with depression also had a higher risk of suicide attempts (hazard ratio 3.02, 95% CI: 1.68–5.42). ESRD patients with severe depression had a significantly higher rate of hospital admissions for depression compared to those with non-severe depression (incidence rate ratio (IRR): 1.82, 95% CI: 1.14–2.93). Furthermore, patients with severe depression were associated with a significantly higher mortality rate compared to those without depression (IRR: 1.42, 95% CI: 1.15–1.76).
Conclusions
Depression is linked to poor survival in ESRD patients, with underlying comorbidities playing a key role in mortality. Given the increased risk of mortality, suicide attempts and hospital admissions, these high-risk patients require enhanced medical attention, particularly those with severe depression.
Psychotic symptoms in depression are linked to worse outcomes, and treatment options are limited. Ketamine and esketamine are effective antidepressants, yet most studies have excluded patients with a history of psychotic symptoms.
Aims
To evaluate by systematic review the efficacy and safety of ketamine and esketamine in treating patients with unipolar or bipolar depressive episodes with psychotic features.
Method
A comprehensive search of the PubMed, Ovid and Web of Science databases was conducted up to 2 November 2023. We included any study that reported the use of ketamine or esketamine in patients with depressive episodes with psychotic symptoms. The primary outcomes assessed were variations in depressive and psychotic symptoms and the incidence of adverse events. The protocol was preregistered in PROSPERO (CRD42023488524).
Results
Ten studies were included, encompassing 60 patients with unipolar depression with psychotic symptoms and 19 patients with bipolar depression with psychotic symptoms. Treatment with (es)ketamine showed mean score changes on the Montgomery–Åsberg Depression Rating Scale ranging from −13.7 to −18.2 points in open-label studies of patients with unipolar depression with psychotic symptoms. Up to 50% of participants achieved remission. The largest study with patients with bipolar depression with psychotic symptoms reported a mean Montgomery–Åsberg Depression Rating Scale score change of −14.9 points. Adverse events were mostly mild and transient. There were no reports of switches to (hypo)mania or deterioration of psychotic symptoms, and in six studies there was substantial improvement of the latter.
Conclusions
The available evidence suggests that (es)ketamine shows antidepressant effects in patients with depressive episodes with psychotic features and has a reasonable safety profile. However, the heterogeneity of the studies included in this review and the high risk of bias warrant caution in interpreting the findings and underscore the need for further trials to confirm these preliminary results.
Accommodation of treatment preferences is known to improve treatment outcomes and increase patient satisfaction, and is further advised in several national guidelines.
Aims
The aim of this study was to systematically review studies that elicited treatment preferences and related determinants among adults with depressive or anxiety disorder for out-patient mental healthcare.
Method
The systematic review was registered in PROSPERO (CRD42024546311). Studies were retrieved from Web of Science, PubMed, CINAHL and PsycINFO. We included studies of all types that assessed treatment preferences of adults with depressive or anxiety disorder for out-patient care. Extracted data on preferences and determinants were summarised and categorised. Preferences were categorised into treatment approaches, psychotherapy delivery and setting, and psychotherapy parameters. Study quality was assessed with the Mixed-Methods Appraisal Tool.
Results
Nineteen studies were included in the review. Preferences examined related to treatment approaches (n = 13), psychotherapy delivery and setting (n = 10), and psychotherapy parameters (n = 7). High heterogeneity in statistical methods and preference types restricted the derivation of robust conclusions, but tendencies toward a preference for psychotherapy (compared with medication), and particularly individual and face-to-face therapy, were observed. Regarding determinants, results were highly diverse and many findings were derived from single studies.
Conclusions
Our review synthesised evidence on treatment preferences and related determinants in out-patient mental healthcare. Results showed considerable heterogeneity regarding preference types, determinants and statistical methods. We highly recommend to develop and use standardised instruments to assess treatment preferences. Care providers should consider preference variance among patients, and provide individualised care.
Peer-supported Open Dialogue (POD) integrates peer practitioners within mental health teams, fostering a collaborative, person-centred and social network approach to care. Although peer practitioners are increasingly involved in Open Dialogue, the role of peer practitioners within such teams remains underexplored.
Aims
This study aimed to explore (a) the experiences of peer practitioners working within Open Dialogue teams in the Open Dialogue: Development and Evaluation of a Social Intervention for Severe Mental Illness trial, and (b) the perspectives of non-peer Open Dialogue practitioners regarding peer involvement. Our further objectives were to understand the nature, degree and perceived impact of peer practitioner involvement in Open Dialogue.
Method
A qualitative study was conducted using semi-structured interviews and joint interviews with peer practitioners (n = 9). Additionally, excerpts from 11 interviews and 4 focus groups (n = 18), in which non-peer practitioners discussed peer practitioners’ contributions in Open Dialogue, were analysed. Thematic analysis was employed to identify key themes.
Results
Three themes were developed. The first focuses on the perceived influence of peer practitioners on Open Dialogue network meetings; the second explores the opportunities and challenges of working as a peer practitioner in Open Dialogue, while the third details the perceived impact of peer practitioners on team and organisational culture.
Conclusions
Open Dialogue’s emphasis on a flattened hierarchy facilitates the integration of peer practitioners, enabling them to contribute meaningfully to network meetings and team culture. Despite the overall positive experiences, peers still faced common challenges faced by those in other services, such as low pay and occasional instances of a compromised, flattened hierarchy.
Providing psychotherapy at 50 sessions in a year (starting twice weekly) led to faster and greater improvements in depression and personality functioning compared to 25 sessions, starting weekly for patients with depression and personality disorder (PD). This study reports long-term dosage effects at 18 and 24 months.
Methods
In a pragmatic, double-randomized clinical trial, 246 outpatients with depression and PD were assigned to (1) 25 or 50 sessions and (2) Short-term Psychodynamic Supportive Psychotherapy (SPSP) or Schema Therapy (ST). Depression severity was assessed with the Beck Depression Inventory-II. Secondary outcomes included diagnostic remission of depression (MINI-plus), PD (SCID-II/SCID-5-P), and treatment-specific measures. Intention-to-treat analyses were conducted.
Results
At 18 and 24 months, BDI-II means did not differ between dosage groups (19.0 for 25 sessions versus 19.1 for 50 sessions; d = −0.01; 95% CI = −0.35-0.37, p = 0.96). The lower-dosage group improved during follow-up (−2.6 BDI points, p = 0.031), which may be partly attributed to additional therapy received by a subgroup. Remission rates at 24 months were 66% for depression and 76% for PD, with no differences between conditions.
Conclusions
Higher psychotherapy dosage led to faster initial improvements, but long-term outcomes were not superior to those achieved with a lower dosage. These results should be interpreted with caution, as unregulated treatment during follow-up reduced the power to detect significant dosage effects. Both SPSP and ST provide viable alternatives to treatments focused solely on depression.
Mood disorders are among the leading causes of disease burden worldwide, with 20–70% of affected individuals experiencing comorbid premenstrual disorders. This systematic review and meta-analysis investigated the comorbidity of premenstrual dysphoric disorder (PMDD) or premenstrual syndrome (PMS) with non-reproductive mood disorders.
Aims
We aimed to determine the pooled prevalence of PMDD/PMS with adult mood disorders, assess the impact of comorbidity on clinical course and summarise the associated neurobiological findings.
Method
Eligible studies were identified through Embase, MEDLINE and APA PsycINFO from inception to 22 January 2024 (PROSPERO, no. CRD42021246796). Studies on women (‘females‘) with diagnoses of PMDD/PMS and mood disorders were included. Risk of bias was assessed using National Institutes of Health quality assessment tools. A random-effects, pooled-prevalence meta-analysis was conducted using the Comprehensive Meta-Analysis software, categorising diagnostic sampling strategies as follows: mood disorders diagnosed first, PMDD/PMS diagnosed first or concurrent diagnoses. A narrative synthesis explored secondary outcomes, including illness course and biomarkers.
Results
A total of 39 studies were included, with 36 of these (n = 3646) contributing to the meta-analysis. Seven studies focused on bipolar disorders, 18 on unipolar depressive disorders and 14 on mixed samples of bipolar and unipolar disorders. Random-effects pooled-prevalence meta-analyses showed consistently high comorbidity rates between PMDD/PMS and mood disorders, ranging from 42% (95% CI: 30%, 55%) to 49% (95% CI: 38%, 60%) across sampling strategies. Risk of bias varied, with methodological heterogeneity noted.
Conclusions
This review underscores high comorbidity rates between PMDD/PMS and mood disorders, regardless of sampling strategy, and highlights the need for research into clinical and neurobiological characteristics specific to this comorbidity. Limitations include study heterogeneity, reliance on cross-sectional designs and provisional PMDD/PMS diagnoses. Future research should address these gaps to inform diagnostic and therapeutic advancements tailored to this population.
Previous meta-analysis of the efficacy of mobile phone applications (mHealth apps) for depression has several limitations, including high risk of bias and heterogeneity in effect sizes across studies, and gaps in understanding of variability in treatment outcomes. We aimed to provide more reliable and clinically relevant findings by conducting a systematic literature search on PubMed, Embase and PsycInfo, focusing on newer studies with minimal risk of bias.
Results
Analysing 17 randomised controlled trials (n = 2821) published between 2020 and 2025, we found a pooled standardised mean difference (s.m.d.) of –0.46 (95% CI –0.64 to –0.28; P < 0.001) relative to the control groups, which indicates a significant reduction in depressive symptoms. Subgroup analyses confirmed efficacy in both adolescents (s.m.d. = –0.42) and adults (s.m.d. = –0.49). Despite evidence of publication bias, 70% of the studies had a low risk of bias, supporting the robustness and reliability of these findings.
Clinical implications
The results underscore the clinical relevance of mHealth apps as scalable and accessible tools for bridging gaps in mental healthcare. Their effectiveness across age groups highlights their potential for broad implementation, with future research needed to refine personalisation, engagement strategies and methodological rigour.
Treatment guidelines recommend evidence-based psychological therapies for adults with intellectual disabilities with co-occurring anxiety or depression. No previous research has explored the effectiveness of these therapies in mainstream psychological therapy settings or outside specialist settings.
Aims
To evaluate the effectiveness of psychological therapies delivered in routine primary care settings for people with intellectual disability who are experiencing co-occurring depression or anxiety.
Method
This study used linked electronic healthcare records of 2 048 542 adults who received a course of NHS Talking Therapies for anxiety and depression in England between 2012 and 2019 to build a retrospective, observational cohort of individuals with intellectual disability, matched 1:2 with individuals without intellectual disability. Logistic regressions were used to compare metrics of symptom improvement and deterioration used in the national programme, on the basis of depression and anxiety measures collected before and at the last attended therapy session.
Results
The study included 6870 adults with intellectual disability and 2 041 672 adults without intellectual disability. In unadjusted analyses, symptoms improved on average for people with intellectual disability after a course of therapy, but these individuals experienced poorer outcomes compared with those without intellectual disability (reliable improvement 60.2% for people with intellectual disability v. 69.2% for people without intellectual disability, odds ratio 0.66, 95% CI 0.63–0.70; reliable deterioration 10.3% for people with intellectual disability v. 5.7% for those without intellectual disability, odds ratio 1.89, 95% CI 1.75–2.04). After propensity score matching, some differences were attenuated (reliable improvement, adjusted odds ratio 0.97, 95% CI 1.91–1.04), but some outcomes remained poorer for people with intellectual disability (reliable deterioration, adjusted odds ratio 1.28, 95% CI 1.16–1.42).
Conclusions
Evidence-based psychological therapies may be effective for adults with intellectual disability, but their outcomes may be similar to (for improvement and recovery) or poorer than (for deterioration) those for adults without intellectual disability. Future work should investigate the impact of adaptations of therapies for those with intellectual disability to make such interventions more effective and accessible for this population.
This article provides a brief introduction (or recapitulation) of what variable types are and how the choice of the variable type may affect which research questions can be answered and the data analysis. The nine-item Patient Health Questionnaire and a simulated data-set are used as an illustration throughout.
Depression is a complex mental health disorder with highly heterogeneous symptoms that vary significantly across individuals, influenced by various factors, including sex and regional contexts. Network analysis is an analytical method that provides a robust framework for evaluating the heterogeneity of depressive symptoms and identifying their potential clinical implications.
Objective:
To investigate sex-specific differences in the network structures of depressive symptoms in Asian patients diagnosed with depressive disorders, using data from the Research on Asian Psychotropic Prescription Patterns for Antidepressants, Phase 3, which was conducted in 2023.
Methods:
A network analysis of 10 depressive symptoms defined according to the National Institute for Health and Care Excellence guidelines was performed. The sex-specific differences in the network structures of the depressive symptoms were examined using the Network Comparison Test. Subgroup analysis of the sex-specific differences in the network structures was performed according to geographical region classifications, including East Asia, Southeast Asia, and South or West Asia.
Results:
A total of 998 men and 1,915 women with depression were analysed in this study. The analyses showed that all 10 depressive symptoms were grouped into a single cluster. Low self-confidence and loss of interest emerged as the most central nodes for men and women, respectively. In addition, a significant difference in global strength invariance was observed between the networks. In the regional subgroup analysis, only East Asian men showed two distinct clustering patterns. In addition, significant differences in global strength and network structure were observed only between East Asian men and women.
Conclusion:
The study highlights the sex-specific differences in depressive symptom networks across Asian countries. The results revealed that low self-confidence and loss of interest are the main symptoms of depression in Asian men and women, respectively. The network connections were more localised in men, whereas women showed a more diverse network. Among the Asian subgroups analysed, only East Asians exhibited significant differences in network structure. The considerable effects of neurovegetative symptoms in men may indicate potential neurobiological underpinnings of depression in the East Asian population.
It remains unclear which individuals with subthreshold depression benefit most from psychological intervention, and what long-term effects this has on symptom deterioration, response and remission.
Aims
To synthesise psychological intervention benefits in adults with subthreshold depression up to 2 years, and explore participant-level effect-modifiers.
Method
Randomised trials comparing psychological intervention with inactive control were identified via systematic search. Authors were contacted to obtain individual participant data (IPD), analysed using Bayesian one-stage meta-analysis. Treatment–covariate interactions were added to examine moderators. Hierarchical-additive models were used to explore treatment benefits conditional on baseline Patient Health Questionnaire 9 (PHQ-9) values.
Results
IPD of 10 671 individuals (50 studies) could be included. We found significant effects on depressive symptom severity up to 12 months (standardised mean-difference [s.m.d.] = −0.48 to −0.27). Effects could not be ascertained up to 24 months (s.m.d. = −0.18). Similar findings emerged for 50% symptom reduction (relative risk = 1.27–2.79), reliable improvement (relative risk = 1.38–3.17), deterioration (relative risk = 0.67–0.54) and close-to-symptom-free status (relative risk = 1.41–2.80). Among participant-level moderators, only initial depression and anxiety severity were highly credible (P > 0.99). Predicted treatment benefits decreased with lower symptom severity but remained minimally important even for very mild symptoms (s.m.d. = −0.33 for PHQ-9 = 5).
Conclusions
Psychological intervention reduces the symptom burden in individuals with subthreshold depression up to 1 year, and protects against symptom deterioration. Benefits up to 2 years are less certain. We find strong support for intervention in subthreshold depression, particularly with PHQ-9 scores ≥ 10. For very mild symptoms, scalable treatments could be an attractive option.
