- Background: Adolescent depression has negative health and economic outcomes in the shortand long-term. Indicated preventive interventions, in particular group based cognitive behavioural therapy (GB-CBT), are ef-fective in preventing depression in adolescents with subsyndromal depression. However, little is known about the cost-effectiveness of these interventions. Methods: A Markov cohort model was used to conduct cost-effectiveness analyses comparing a GB-CBT indicated preventive intervention for depression, to a no-intervention option in a Swedish setting. Taking a time horizon of 5and 10 years, incremental differences in societal costs and health benefits expressed as differences in the proportion of cases of depression prevented, and as quality adjusted life years (QALYs) gained were estimated. Through univariate and probabilistic sensitivity analyses, the robustness of the results was explored. Costs, presented in 2018 USD, and effects were discounted at a yearly rate of 3%. Results: The base-case analysis showed that GB-CBT indicated preventive intervention incurred lower costs, prevented a larger proportion of cases of depression and generated higher QALYs compared to the no -intervention option for both time horizons. Offering the intervention was even a cost saving strategy and demonstrated a probability of being cost-effective of over 95%. In the sensitivity analyses, these results were robust to the modelling assumptions. Limitations: The study considered a homogeneous cohort and assumed a constant annual decay rate of the relative treatment effect. Conclusions: GB-CBT indicated preventive interventions for depression in adolescence can generate good value for money compared to leaving adolescents with subsyndromal depression untreated.

- Background: Depression in adolescence is associated with increased healthcare consumption in adulthood, but prior research has not recognized the heterogeneity of depressive disorders. This paper investigated the additional healthcare usage and related costs in mid-adulthood for individuals with adolescent depression, and examined the mediating role of subsequent depression in early adulthood.Methods: This study was based on the Uppsala Longitudinal Adolescent Depression Study, initiated in Sweden in the early 1990s. Depressive disorders were assessed in adolescence (age 16-17) and early adulthood (age 19-30). Healthcare usage and related costs in mid-adulthood (age 31-40) were estimated using nationwide population-based registries. Participants with specific subtypes of adolescent depression (n = 306) were compared with matched non-depressed peers (n = 213).Results: Women with persistent depressive disorder (PDD) in adolescence utilized significantly more healthcare resources in mid-adulthood. The association was not limited to psychiatric care, and remained after adjustment for individual and parental characteristics. The total additional annual cost for a single age group of females with a history of PDD at a population level was estimated at 3.10 million USD. Depression recurrence in early adulthood mediated the added costs for psychiatric care, but not for somatic care.Limitations: Primary health care data were not available, presumably resulting in an underestimation of the true healthcare consumption. Estimates for males had limited precision due to a relatively small male proportion.Conclusions: On a population level, the additional healthcare costs incurred in mid-adulthood in females with a history of adolescent PDD are considerable. Early treatment and prevention should be prioritized.

- Adolescent depression is linked to adult ill-health and functional impairment, but recent research suggests that individual/contextual factors might account for this association. This study aimed to test whether the clinical heterogeneity of adolescent depression is related to marginalization from the labor market across early to middle adulthood. Data were drawn from the Uppsala Longitudinal Adolescent Depression Study, a community-based cohort initially assessed with structured clinical interviews at age 16-17. The cohort (n = 321 depressed; n = 218 nondepressed) was followed up after 2+ decades through linkage to nationwide population-based registries. Outcomes included consecutive annual data on unemployment, work disability, social welfare recipiency, and a composite marginalization measure, spanning from age 21 to 40. Longitudinal associations were examined using logistic regression analysis in a generalized estimating equations modeling framework. Subsequent depressive episodes and educational attainment in early adulthood were explored as potential pathways. The results showed that adolescent depression was associated with adult marginalization outcomes, but the strength of association varied across depressed subgroups. Adolescents with persistent depressive disorder had higher odds of all outcomes, including the composite marginalization measure (adjusted OR = 2.0, 95% CI = 1.4-2.7, p < 0.001), and this was partially (31%) mediated by subsequent depressive episodes in early adulthood. Exploratory moderation analysis revealed that entry into tertiary education mitigated the association with later marginalization, but only for adolescents with episodic major depression. In conclusion, the risk for future labor market marginalization is elevated among depressed adolescents, particularly those presenting with persistent depressive disorder. Targeted interventions seem crucial to mitigate the long-lasting impact of early-onset depression.

- PURPOSE: Depression at all ages is recognized as a global public health concern, but less is known about the welfare burden following early-life depression. This study aimed to (1) estimate the magnitude of associations between depression in adolescence and social transfer payments in adulthood; and (2) address the impact of major comorbid psychopathology on these associations.METHODS: This is a longitudinal cohort study of 539 participants assessed at age 16-17 using structured diagnostic interviews. An ongoing 25-year follow-up linked the cohort (n = 321 depressed; n = 218 nondepressed) to nationwide population-based registries. Outcomes included consecutive annual data on social transfer payments due to unemployment, work disability, and public assistance, spanning from age 18 to 40. Parameter estimations used the generalized estimating equations approach.RESULTS: Adolescent depression was associated with all forms of social transfer payments. The estimated overall payment per person and year was 938 USD (95% CI 551-1326) over and above the amount received by nondepressed controls. Persistent depressive disorder was associated with higher recipiency across all outcomes, whereas the pattern of findings was less clear for subthreshold and episodic major depression. Moreover, depressed adolescents presenting with comorbid anxiety and disruptive behavior disorders evidenced particularly high recipiency, exceeding the nondepressed controls with an estimated 1753 USD (95% CI 887-2620).CONCLUSION: Adolescent depression is associated with considerable public expenditures across early-to-middle adulthood, especially for those exposed to chronic/persistent depression and psychiatric comorbidities. This finding suggests that the clinical heterogeneity of early-life depression needs to be considered from a longer-term societal perspective.

Adulthood Outcomes of Child and Adolescent Depression : From Mental Health to Social Functioning
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Depression is a common mental disorder affecting people across the lifespan, with first onset frequently occurring in the teenage years. The disorder is costly to society and constitutes one of the leading causes of disability in youths and adults worldwide. Research demonstrates that depression in childhood or adolescence is linked to adverse adult consequences, including mental health problems, physical health issues, various social difficulties, and economic hardships. While the specific factors and mechanisms associated with these long-term adversities are not well understood, previous studies point to the relevance of considering the heterogeneity in early-life depression.The overarching aim of this doctoral thesis was to shed more light on long-term outcomes of childhood and adolescent depression across multiple life domains. This work made use of extensive follow-up data gathered in Sweden and USA, as part of two community-based longitudinal cohort studies of depressed and nondepressed youths prospectively followed into adulthood. In the Uppsala Longitudinal Adolescent Depression Study, participants were interviewed around age 16 (n=631) and age 31 (n=409). Using linkage to nationwide population-based registries, participants were followed up around age 40 (n=576). In the Great Smoky Mountains Study, participants were interviewed at repeated occasions in childhood and adolescence (n=1,420), and at further follow-ups in adulthood extending up to age 30 (n=1,336).Findings from this work suggest that childhood/adolescent depression can have long-lasting associations with a broad spectrum of adverse outcomes. First, the risk of adult depression is known to be elevated among those exposed to depression in early life; however, depressed youths experiencing major conflicts with parents may be at an additionally increased risk of subsequent depression recurrence. Second, early-life depression was found to be associated with higher levels of adult psychiatric disorders, and also with worse health, criminal, and social functioning, even when accounting for a multitude of potential confounders. Third, early-life depression was predictive of poor labor market outcomes, especially for those with persistent depression. This link was partially mediated by the course of depression. Fourth, the welfare burden associated with early depression amounted to considerable public expenditures in adulthood, particularly for those with persistent depression or comorbid psychiatric conditions such as anxiety and disruptive behavior disorders.The adverse long-term consequences in the wake of early-life depression underscore the importance of prevention and treatment approaches that are both efficacious and cost-effective. Such targeted efforts may have the potential to avert later ill-health, impairment, and possibly also economic disadvantage.

- Experiencing conflictual relations with one's parents while growing up has been linked to onset, recurrence, and worse treatment outcome of adolescent depression. While this suggests that significant problems in the parent-youth relationship make depressive disorders more relentless, it is not clear whether this effect lasts into adulthood. Our aim was to examine if major and minor conflict with parents while growing up predicts depression in adulthood in youth with and without a history of depression. We utilized data from the Uppsala Longitudinal Adolescent Depression Study. This community-based cohort was assessed with structured diagnostic interviews both at age 16-17 and at follow-up 15 years later. The analyses included 382 individuals (227 with a history of child or adolescent depression; 155 peers without such a history). Binary logistic regression was used, adjusting for sex, disruptive behavior disorders, and additional family-related adversities. Among individuals with adolescent depression, major conflict with parents was strongly associated with adult depression (adjusted OR 2.28, 95% CI 1.07-4.87). While major conflict with parents was rare among non-depressed controls, a non-significant association of similar magnitude was still observed. Minor conflict, on the other hand, was not significantly associated with adult depression. Overall, conflict with parents did not predict adult anxiety disorders, substance use, suicidal behavior, somatoform disorders, or psychotic disorders. In conclusion, major parent-youth conflict during upbringing seems to be linked with an increased risk of depression in adulthood. These findings underscore the need to consider contextual/familial factors in the prevention and clinical management of early-life depression.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To present the Uppsala Longitudinal Adolescent Depression Study, initiated in Uppsala, Sweden, in the early 1990s. The initial aim of this epidemiological investigation was to study the prevalence, characteristics and correlates of adolescent depression, and has subsequently expanded to include a broad range of social, economic and health-related long-term outcomes and cost-of-illness analyses.Participants: The source population was first-year students (aged 16-17) in upper-secondary schools in Uppsala during 1991-1992, of which 2300 (93%) were screened for depression. Adolescents with positive screening and sex/age-matched peers were invited to a comprehensive assessment. A total of 631 adolescents (78% females) completed this assessment, and 409 subsequently completed a 15year follow-up assessment. At both occasions, extensive information was collected on mental disorders, personality and psychosocial situation. Detailed social, economic and health-related data from 1993 onwards have recently been obtained from the Swedish national registries for 576 of the original participants and an age-matched reference population (N=200 000).Findings to date: The adolescent lifetime prevalence of a major depressive episode was estimated to be 11.4%. Recurrence in young adulthood was reported by the majority, with a particularly poor prognosis for those with a persistent depressive disorder or multiple somatic symptoms. Adolescent depression was also associated with an increased risk of other adversities in adulthood, including additional mental health conditions, low educational attainment and problems related to intimate relationships.Future plans: Longitudinal studies of adolescent depression are rare and must be responsibly managed and utilised. We therefore intend to follow the cohort continuously by means of registries. Currently, the participants are approaching mid-adulthood. At this stage, we are focusing on the overall long-term burden of adolescent depression. For this purpose, the research group has incorporated expertise in health economics. We would also welcome extended collaboration with researchers managing similar datasets.

Forskningsöversikt (refereegranskat)abstract
- Objective: This study aimed to describe the quantity, scope, and fundamental characteristics of recently published randomized controlled trials (RCTs) of psychological interventions.Methods: We queried two major databases (PsycINFO and PubMeD) for primary reports published in 2010 of RCTs of psychological interventions for participants with a medical condition. We collected data on the characteristics of the trials, participants, interventions, outcomes, and reports.Results: Of 3,696 retrieved reports 295 primary publications were included. About half (53%) of trials included participants with a mental disorder and more than half evaluated interventions based on a cognitive behavioral therapy (CBT) framework. A majority of trials recruited participants in North America and Europe (79%). A minority of the trials focused on children and adolescents (17%) or the elderly (8%). The median sample size of the intervention arm was n = 41. Thirty-nine percent of trials reported solely patient-reported outcomes. Only 5% of reports indicated funding from for-profit organizations. The median 2010 impact factor of the journals in which reports were published was 2.96.Conclusion: This snapshot of the research on psychological interventions suggests that the evidence base for psychological interventions is expanding mainly for CBT interventions for adults in high-income countries. Although the restrictive inclusion criteria limit the generalizability of these results, researchers and funding agencies might be advised to strive for greater diversity regarding interventions, geographical/cultural settings and age groups. Regularly updated reviews of this research field, with gradually refined methodology and increased scope, may further inform funders and researchers.

- Objective: Depression is common, impairing, and the leading cause of disease burden in youths. This study aimed to identify the effects of childhood/adolescent depression on a broad range of longer-term outcomes.Method: The analysis is based on the prospective, representative Great Smoky Mountains Study of 1,420 participants. Participants were assessed with the structured Child and Adolescent Psychiatric Assessment interview up to 8 times in childhood (age 9 similar to 16 years; 6,674 observations; 1993-2000) for DSM-based depressive disorders, associated psychiatric comorbidities, and childhood adversities. Participants were followed up 4 times in adulthood (ages 19, 21, 25, and 30 years; 4,556 observations of 1,336 participants; 1999-2015) with the structured Young Adult Psychiatric Assessment Interview for psychiatric outcomes and functional outcomes.Results: In all, 7.7% of participants met criteria for a depressive disorder in childhood/adolescence. Any childhood/adolescent depression was associated with higher levels of adult anxiety and illicit drug disorders and also with worse health, criminal, and social functioning; these associations persisted when childhood psychiatric comorbidities and adversities were accounted for. No sex-specific patterns were identified. However, timing of depression mattered: individuals with adolescent-onset depression had worse outcomes than those with child-onset. Average depressive symptoms throughout childhood and adolescence were associated with more adverse outcomes. Finally, specialty mental health service use was protective against adult diagnostic outcomes.Conclusion: Early depression and especially persistent childhood/adolescent depressive symptoms have robust, lasting associations with adult functioning. Some of these effects may be attenuated by service use.
