Background: Depression in adolescence is a serious major global health problem with increasing rates of prevalence. Measures of depression that are valid for young people are clearly needed in clinical contexts., Methods: The study included 577 patients from child and adolescent psychiatry ( n  = 471) and primary care ( n  = 106) aged 12-22 years in Sweden (M age =16.7 years; 76% female). The reliability and validity for Montgomery-Åsberg Depression Rating Scale - Youth (MADRS-Y) were investigated. To confirm the latent structure, we used a single-factor confirmatory factor analysis (CFA). A Kruskal-Wallis test was performed to test total score differences between diagnostic groups. Using Spearman's rho correlations, we examine whether single items in the MADRS-Y correlate with suicidal ideation measured by The Suicidal Ideation Questionnaire-JR ( SIQ-JR)., Results: The internal consistency using McDonald's coefficient omega was excellent. The CFA of the 12-item MADRS-Y supported a one factor structure. Evidence of convergent and discriminant validity was shown. There was a significant difference in MADRS-Y scores across diagnostic groups, with higher results for depressive disorders. A strong correlation with suicidal ideation was found for two items., Conclusions: The results support MADRS-Y as a brief, reliable, and valid self-report questionnaire of depressive symptoms for young patients in a clinical setting.

Objective: Observed and predicted increases in the global burden of disease caused by major depressive disorder (MDD) highlight the need for psychometrically robust multi-dimensional measures to use for clinical and research purposes. Reynolds Adolescent Depression Scale second edition (RADS-2) is an internationally well-validated scale measuring different dimensions of adolescent depression. The Swedish version has previously only been evaluated in a normative sample. Methods: We collected data from patients in child and adolescent psychiatry and primary care and performed: (1) Confirmatory factor analysis (CFA) to evaluate the established four-factor structure, (2) Analyses of reliability and measurement invariance, (3) Analyses of convergent and discriminant validity using the Montgomery-Asberg Depression Rating Scale, the depression subscales of the Beck Youth Inventories and the Revised Child Anxiety and Depression Scale, as well as the Patient Reported Outcome Measurements Information System, peer-relationships and physical activity item banks. Results: Recruited participants ( n  = 536, 129 male and 407 female, mean age 16.45 years, SD  = 2.47, range 12 - 22 years) had a variety of psychiatric diagnoses. We found support for the four-factor structure and acceptable to good reliability for the subscale and total scores. Convergent and discriminant validity were good. Measurement invariance was demonstrated for age, sex, and between the present sample and a previously published normative sample. The RADS-2-scores were significantly higher in the present sample than in the normative sample. In this clinical study, the Swedish RADS-2 demonstrated good validity and acceptable to good reliability. Our findings support the use of RADS-2 in Swedish clinical and research contexts.

Depression in adolescents and young adults is an increasing global health concern. Available treatments are not sufficiently effective and relapse rates remain high. The novel group-treatment program "Training for Awareness, Resilience and Action" (TARA) targets specific mechanisms based on neuroscientific findings in adolescent depression. TARA is framed within the National Institute of Mental Health's Research Domain Criteria and has documented feasibility and preliminary efficacy in the treatment of adolescent depression. Since neurodevelopment continues well into the mid-twenties, age-adapted treatments are warranted also for young adults. Patients 15-22 years old, with either major depressive disorder (MDD) or persistent depressive disorder (PDD) according to the DSM-IV/5 or a rating >40 on the clinician rating scale Children's Depression Rating Scale-Revised (CDRS-R), will be recruited from specialized Child and Adolescent Psychiatry and local Youth-Clinics and randomized to either TARA or standard treatment, including but not limited to antidepressant medication and/or psychotherapy. Outcome measures will be obtained before randomization (T 0 ), after 3 months of treatment (T 1 ) and at 6-months- (T 2 ) and 24-months- (T 3 ) follow-up. Additionally, dose-response measures will be obtained weekly in the TARA-arm and measures for mediation-analysis will be obtained halfway through treatment (T 0.5 ). Primary outcome measure is Reynolds Adolescent Depression Scale (RADS-2) score at T 1 . Secondary outcome measures include RADS-2 score at T 2 , Multidimensional Anxiety Scale for Children at T 1 and T 2 , and CDRS-R at T 1 . Additional outcome measures include self-report measures of depression-associated symptoms, systemic bio-indicators of depression from blood and hair, heartrate variability, brain magnetic resonance imaging, as well as three-axial accelerometry for sleep-objectivization. Qualitative data will be gathered to reach a more comprehensive understanding of the factors affecting adolescents and young adults with depression and the extent to which the different treatments address these factors. In summary, this article describes the design, methods and statistical analysis plan for pragmatically evaluating the clinical effectiveness of TARA. This will be the first RCT to examine the effects of TARA compared to standard treatment for adolescents and young adults with MDD or PDD. We argue that this study will extend the current knowledgebase regarding the treatment of depression.

Background: This study is part of the Swedish initiative for the establishment of standardized, modern patient-reported measures for national use in Swedish healthcare. The goal was to translate and culturally adapt eight pediatric Patient-Reported Outcomes Measurement Information System (PROMIS ® ) item banks (anger, anxiety, depressive symptoms, family relationships, fatigue, pain interference, peer relationships and physical activity) into Swedish., Methods: Authorization to translate all currently available pediatric PROMIS item banks (autumn, 2016) into Swedish was obtained from the PROMIS Health Organization. The translation followed the Functional Assessment of Chronic Illness Therapy translation recommendations with one major modification, which was the use of a bilingual multi-professional review workshop. The following steps were applied: translation, reconciliation, a two-day multi professional reviewer workshop, back translation, and cognitive debriefing with eleven children (8-17 years) before final review. The bilingual multi-professional review workshop provided a simultaneous, in-depth assessment from different professionals. The group consisted of questionnaire design experts, researchers experienced in using patient-reported measures in healthcare, linguists, and pediatric healthcare professionals., Results: All item banks had translation issues that needed to be resolved. Twenty-four items (20.7%) needed resolution at the final review stage after cognitive debriefing. The issues with translations included 1. Lack of matching definitions with items across languages (6 items); 2. Problems related to language, vocabulary, and cultural differences (6 items); and 3. Difficulties in adaptation to age-appropriate language (12 items)., Conclusions: The translated and adapted versions of the eight Swedish pediatric PROMIS item banks are linguistically acceptable. The next stage will be cross-cultural validation studies in Sweden. Despite the fact that there are cultural differences between Sweden and the United States, our translation processes have successfully managed to address all issues. Expert review groups from already-established networks and processes regarding pediatric healthcare throughout the country will facilitate the future implementation of pediatric PROMIS item banks in Sweden., (© 2021.

Background: Due to the sharp global increase in prevalence of adolescent major depressive disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders, we need internationally validated tools for multi-dimensional assessment. Reynolds Adolescent Depression Scale second edition (RADS-2) measures dysphoric mood, anhedonia/negative affect, negative self-evaluation and somatic complaints and is widely used internationally, but not yet available in Swedish., Aim: The aim of this study is to test the psychometric characteristics of the Swedish version of RADS-2 in a normative sample., Material and Method: Data was gathered from junior and high school students in Northern Sweden ( N  = 637). We performed: 1. Confirmatory factor analysis to examine the 4-factor structure proposed by Reynolds, 2. Measurement invariance analysis for sex (girls, boys) and age group (12-15 years, 16-20 years). 3. Reliability testing and 4. Tests for concurrent, discriminant and convergent validity using Beck's Youth Inventories of Emotional and Social Impairment Depression and Anger subscales, the Patient Reported Outcome Measurements Information System, Anxiety and Friends subscales and the World Health Organization Wellness Index., Results: The sample consisted of n  = 637 students ( n  = 389 girls and n  = 248 boys), mean age 15.73 (SD = 1.76); 12-20 years. The 4-factor structure was confirmed, as well as measurement invariance for sex and age group. Reliability was acceptable to excellent for all subscales and RADS-2 total scale. Concurrent, convergent and discriminant validity was good., Conclusion: The Swedish version of RADS-2 showed acceptable reliability and validity in a Swedish normative sample.

Background: Previous studies suggest an overall increase of adolescent mental health symptoms globally since the 1980s until today, especially an increase of internalizing symptoms in girls. Due to methodological limitations of these studies, further studies are warranted to obtain a more solid knowledgebase., Methods: This study was cross-sectional and compared two separate but geographically identical groups of adolescents in a middle-sized industrial municipality in Northern Sweden at two time-points [(i) 1981, n = 1083, (505 girls, 577 boys), response rate 99.7%; (ii) 2014, n = 682, (338 girls, 344 boys), response rate 98.3%]. All students in their last year of compulsory school were included. The same self-report questionnaire, consisting of four sub-scales (functional somatic-, anxiety-, depressive symptoms and conduct problems), was used at both occasions. Data were analyzed with descriptive statistics, two-way ANOVA and general linear model., Results: Symptoms of anxiety and depression and functional somatic symptoms, increased among both boys and girls from 1981 until 2014 (P < 0.001 for all subscales), and the increase of these symptoms was higher in girls. Conduct problems were significantly higher in boys in 1981 and decreased over time so that in 2014 there was no longer a significant difference between boys and girls regarding conduct problems (P = 0.286)., Conclusion: In this population-based study spanning over 30 years, both girls and boys showed increasing internalizing problems, while conduct problems decreased. To halt this trend, we need a deeper understanding of the impact of the major societal changes that have occurred during the last three decades., (© The Author(s) 2019.
