Adolescent mental health appears to be in crisis, yet few studies have comprehensively charted the course of common mental disorders (CMDs; depression and anxiety) across this key life stage. We aimed to describe the course of CMD symptoms in adolescence by summarising annual prevalence, cumulative incidence, and course for depression and anxiety, both separately and as comorbid CMDs, by sex assigned at birth in a contemporary Australian cohort. The Child to Adult Transition Study (CATS) was established in 2012 to form a representative cohort of adolescents in Melbourne, VIC, Australia. 43 schools were recruited using a stratified sampling approach, and all 2289 students aged 8-9 years were invited to participate. 1239 (54·1%) students obtained parental written informed consent and were followed up annually from 2012 to 2019 for a total of ten waves. Data from waves 3-10 (ages 10 to 18 years) were used for the current study and analysed to describe the course of symptoms of CMDs across adolescence. Primary measures of interest were clinically relevant depressive symptoms, clinically relevant anxiety symptoms, and any CMD (clinically relevant depressive or anxiety symptoms) at waves 3-10. A secondary measure of interest was comorbid CMDs (concurrent reporting of clinically significant anxiety and depressive symptoms) at waves 3-10. Depressive symptoms in the past 2 weeks were self-reported using the 13-item validated Short Mood and Feelings Questionnaire (SMFQ) at each wave, with a threshold score of 12 or more indicating clinically relevant symptoms. Anxiety symptoms in the past two weeks were self-reported using an 8-item shortened version of the Spence Children's Anxiety Scale (SCAS) at each wave, with a threshold score of 11 or higher indicating clinically relevant symptoms. The course of CMDs was described using annual prevalence, cumulative incidence for depression and anxiety, separately and combined. Missing data were handled via multiple imputation. An author with lived experience was involved in the research and writing process. Of the 1239 adolescents who participated in the study, 667 (53·8%) were female and 572 (46·2%) were male. 769 (62·1%) of 1239 were classified as socioeconomically advantaged, 675 (66·4%) of the 1016 with available data had a mother whose highest level of education was vocational or tertiary, and 579 (70·7%) of the 819 participants with ethnicity data identified as Anglo-Celtic or European. Overall, incidence of any clinically significant CMD symptoms during adolescence was 74% (95% CI 70-77; 84% [81-88] for females and 61% [55-66] for males). Independently, incidences of clinically significant depressive symptoms and anxiety symptoms were 65% (62-68) and 58% (55-62), respectively. Incidence of comorbid CMD was 48% (45-52). The estimated mean ages of first report in adolescence for both sexes were 14·1 years (95% CI 13·9-14·4) and 13·6 years (3·3-13·9) for depressive and anxiety symptoms, respectively. Of those who reached the threshold score for any CMD between ages 10 and 18 years, over half had a chronic (three or more waves) course (depression 54% [49-60]; anxiety 52% [47-58]), and a third met criteria for full remission at any subsequent wave (depression 30% [25-35]; anxiety 33% [27-39]). Females were consistently estimated to have a worse course of adolescent CMDs compared with males (eg, 64% [58-70] of females had a chronic course of depressive symptoms vs 37% [26-48] of males). In this contemporary multi-wave cohort study, almost three-quarters of adolescents reported CMD symptoms. The likelihood of chronicity of CMD symptoms (ie, recurrence) was high. Universal responses are urgently required to address this considerable public health problem. National Health and Medical Research Council of Australia and the Royal Children's Hospital Foundation.

Psychotherapy outcomes are typically measured in terms of symptom relief. However, this method might overlook important changes from clients' perspectives when they are asked to report on them. A more client-centred approach might bring a deeper understanding of psychotherapy outcomes. We aimed to evaluate the outcomes identified by clients within qualitative psychotherapy research. The PsycArticles, PsycInfo, and MEDLINE Complete databases were searched for English language studies published until Nov 11, 2023. Additional studies were identified through references in the primary studies and previous meta-analyses or systematic reviews. Search terms were related to psychotherapy and counselling, clients' or patients' experiences, psychotherapy outcomes and changes, post-treatment perspectives, and types of qualitative methods. Qualitative studies on client-identified outcomes of individual psychotherapy were included. Findings related to clients' perceptions of psychotherapy outcomes were extracted (by ML and checked by TR and LT) and analysed (by all authors) using the descriptive-interpretative meta-analytic approach. All authors have personally experienced psychotherapy as clients. This study was pre-registered with PROSPERO (CRD42021277330). We included 177 studies in the qualitative meta-analysis, from 24 countries, including descriptions from 2908 clients. Most of the studies were of good quality; they covered a wide range of therapeutic approaches and diagnoses. The descriptions of psychotherapy outcomes were classified into 60 meta-categories and grouped into ten clusters. These clusters related to clients' relational and social functioning; their emotional functioning; self-awareness, self-understanding, and more adaptive cognitive processing; behavioural functioning; developing their own resources; clients' attitudes towards themselves; generally embracing life; symptom and problem change; and more general wellbeing. The tenth cluster was outcomes that could not be clearly attributed to psychotherapy, which was considered outside the scope of this study. The meta-analysis showed that clients value outcome dimensions beyond symptom reduction, such as deeper self-understanding, enhanced self-agency, and greater social engagement. By examining psychotherapy outcomes across various diagnoses and therapeutic approaches, we highlight limitations in traditional outcome measures, showing the need for more comprehensive, client-centred assessment tools and the value of incorporating qualitative methods into understanding dimensions of change.

The association between lithium use and chronic kidney disease, and the effect of comorbidities on this association are poorly understood. Our aim was to examine the risk of developing stage 3 or higher chronic kidney disease among people receiving lithium therapy. This was a retrospective, population-based cohort study of all adults (aged ≥18 years) in Iceland treated with lithium for a mood disorder who had two or more serum creatinine measurements available in the years 2008-17, irrespective of duration of lithium therapy, identified from the Prescription Medicines Register of the Directorate of Health, or through blood lithium measurements. The control group comprised all eligible outpatients with mood disorders (ICD-10 codes F30-F39) who had not been prescribed lithium and who had attended the national tertiary referral centre in 2014-16. Individuals with chronic kidney disease (identified by ICD codes or an estimated glomerular filtration rate [eGFR] <60 mL/min per 1·73 m2) before Jan 1, 2008, or those with glomerular disease, genetic or congenital kidney disease, or small kidneys diagnosed before or after 2008 were excluded. Chronic kidney disease stages 3 and higher were defined according to the 2012 Kidney Disease: Improving Global Outcomes Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease, and the eGFR was calculated from serum creatinine; all ICD-10 and ICD-9 diagnosis codes, serum creatinine and blood lithium concentrations, and urine albumin-to-creatinine ratios were obtained from health-care institutions and laboratories. Risk of developing stage 3 or higher chronic kidney disease between Jan 1, 2008, and Dec 31, 2017, was assessed using time-to-event regression analysis, accounting for competing risk of death. People with lived experience were not involved in the design or conduct of this study. We identified 4310 individuals (2695 who had received lithium and 1615 control participants), of whom 3198 were included in the study. 2025 (75·1%) individuals in the lithium group (1165 [57·5%] female and 860 [42·5%] male) and 1173 (72·6%) in the control group (737 [62·8%] female and 436 [37·2%] male) were included in the study at end of follow-up. The mean age of the study sample at the end of follow-up was 46·6 years (SD 16·4; range 18·5-98·9). Ethnicity data were not available. In the lithium group, 211 (10·4%) of 2025 individuals developed stage 3 or higher chronic kidney disease, compared with 35 (3·0%) of 1173 individuals in the control group (hazard ratio [HR] 1·90, 95% CI 1·32-2·75 after adjusting for sex, age, and comorbid conditions). Compared with control participants, the risk of stage 3 or higher chronic kidney disease was significantly increased for subgroups with a mean blood lithium concentration of 0·60-0·79 mmol/L (HR 2·93, 95% CI 1·97-4·36) or 0·80-0·99 mmol/L (4·31, 2·66-6·99), but not for the subgroup with a mean blood lithium concentration of 0·30-0·59 mmol/L (1·22, 0·78-1·90). Analyses also showed that age, initial eGFR, diabetes, and history of acute kidney injury were significant risk factors for developing stage 3 or higher chronic kidney disease. Individuals with mood disorders receiving lithium treatment had an increased risk of developing stage 3 or higher chronic kidney disease in a blood concentration-dependent manner. We also found that other factors, including age, initial eGFR, and comorbidities were associated with increased risk of for developing stage 3 or higher chronic kidney disease. Overall, our findings suggest that in addition to considering other risk factors (eg, age or clinical comorbidities), careful monitoring of blood lithium concentrations and use of the lowest effective lithium dose for adequate mood stabilisation is recommended for helping to mitigate the risk of chronic kidney disease.

Access to effective treatment for major depressive disorder remains limited and difficult to track across place and time. We analysed the available data on minimally adequate treatment (MAT) for major depressive disorder globally with the aim of providing a useful metric against which to monitor national responses to the growing public health burden imposed by major depressive disorder. MAT was defined as pharmacotherapy (1 month of medication, plus four visits to a medical doctor) or psychotherapy (eight visits with any professional). From existing reviews, we identified mental health surveys that assessed major depressive disorder within the general population as well as health service uptake by individuals with major depressive disorder. Data by ethnicity were not available. Estimates of MAT, antidepressant use, or use of any mental health service were extracted. The latter two estimates were adjusted to reflect likely MAT rates via a network meta-analysis. Adjusted MAT estimates were analysed via a Bayesian meta-regression using the Disease Modelling Meta-Regression (DisMod-MR 2.1) tool. This analysis estimated MAT coverage among people with major depressive disorder by age, sex, location, and year. Final MAT estimates were standardised by age and sex against the existing age and sex distribution of people with major depressive disorder globally. People with lived experience were involved in the design, preparation, interpretation, and writing of this manuscript. The analysed dataset included 145 estimates from 32 studies, covering 31 countries, 14 regions, and six super-regions. The proportion of people with major depressive disorder receiving MAT globally in 2021 was 9·1% (95% uncertainty interval 7·2-11·6), with 10·2% (8·2-13·1) of females and 7·2% (5·7-9·3) of males with major depressive disorder receiving MAT. MAT coverage was highest in high-income locations (27·0% [21·7-34·4]), with Australasia having the highest rate (29·2% [21·4-40·8]). MAT coverage was lowest in sub-Saharan Africa (2·0% [1·5-2·6]), within which western sub-Saharan Africa (1·8% [1·4-2·5]) had the lowest coverage. Seven countries (Australia, Belgium, Canada, Germany, the Netherlands, South Korea, and Sweden) were estimated to have MAT coverage exceeding 30%, while 90 countries were estimated to have coverage lower than 5%. Despite many gaps in the available data, estimates show that, globally, most individuals with major depressive disorder do not receive MAT. Services must improve to reach a global coverage that better meets the mental health needs of those with major depressive disorder. Urgent attention should be given to the scale-up of effective intervention strategies, especially in low-income and middle-income countries, as well as further research into better quality treatment options for major depressive disorder. We present a means by which the MAT gap for major depressive disorder can be quantified, to monitor and inform action by governments and international partners.
