Objective
Adolescents with anorexia (AN) and bulimia nervosa (BN) often struggle with emotion regulation (ER). These difficulties have predominantly been assessed across emotions, without considering ...adaptive and maladaptive ER separately. We compared adolescents with AN or BN to healthy adolescents (HCs) regarding the adaptive and maladaptive ER of three emotions.
Method
A treatment‐seeking sample of 197 adolescents (atypical/full‐threshold AN: N = 118, atypical/full‐threshold BN: N = 32; HC: N = 47) reported emotion‐specific ER with the FEEL‐KJ questionnaire. Mixed models were calculated for adaptive and maladaptive ER to assess differences between emotions (anxiety, anger, and sadness) and groups (AN, BN, and HC).
Results
Main effects of emotion (p < .001) and group (p < .001) were found, but no interaction effects were found (p > .05). Post hoc tests showed lower maladaptive and higher adaptive ER for anxiety than anger or sadness (p < .001). AN and BN reported lower adaptive (p < .001) and higher maladaptive ER than HCs (p < .001). BN showed the highest levels of maladaptive ER (p = .009).
Discussion
The differences between AN and BN in adaptive and maladaptive ER should be considered. Furthermore, investigating differences in ER of other emotions in eating disorders might be promising.
Sleep problems are a risk factor for the development of depressive disorders and influence the severity and treatment of depressive symptoms negatively. To enhance treatment for depression in young ...people, it is important to advance the understanding of the relationship between sleep problems and depressive symptoms. Since deficits in emotion regulation are discussed as possible underlying mechanisms, the present study investigated the mediating effect of maladaptive and adaptive strategies for emotion regulation on the association between sleep problems and depressive symptoms. Emotion regulation strategies, depression and sleep quality were assessed via self-report in a large clinical sample of 602 adolescents (age 13–18 years) who reported clinically relevant symptoms of depression. The questionnaires were assessed at admission for inpatient psychiatric treatment. Correlation and mediation analyses were performed. There was a significant partial mediation effect (β = 0.554,
p

= 0.527), indicating that sleep problems influenced depressive symptoms via the decreased use of adaptive strategies and the increased use of maladaptive strategies. Additionally, a direct effect of sleep problems on depressive symptoms emerged (β = 0.251,

The revised version of the Beck Depression Inventory (BDI-II) is one of the most frequently applied questionnaires not only in adults, but also in adolescents. To date, attempts to identify a ...replicable factor structure of the BDI-II have mainly been undertaken in adult populations. Moreover, most of the studies which included minors and were split by gender lacked confirmatory factor analyses and were generally conducted in healthy adolescents. The present study therefore aimed to determine the goodness of fit of various factor models proposed in the literature in an adolescent clinical sample, to evaluate alternative solutions for the factor structure and to explore potential gender differences in factor loadings. The focus was on testing bifactor models and subsequently on calculating bifactor statistical indices to help clarify whether a uni- or a multidimensional construct is more appropriate, and on testing the best-fitting factor model for measurement invariance according to gender. The sample comprised 835 adolescent girls and boys aged 13-18 years in out- and inpatient setting. Several factor models proposed in the literature provided a good fit when applied to the adolescent clinical sample, and differences in goodness of fit were small. Exploratory factor analyses were used to develop and test a bifactor model that consisted of a general factor and two specific factors, termed cognitive and somatic. The bifactor model confirmed the existence of a strong general factor on which all items load, and the bifactor statistical indices suggest that the BDI-II should be seen as a unidimensional scale. Concerning measurement invariance across gender, there were differences in loadings on item 21 (Loss of interest in sex) on the general factor and on items 1 (Sadness), 4 (Loss of pleasure), and 9 (Suicidal Thoughts) on the specific factors. Thus, partial measurement invariance can be assumed and differences are negligible. It can be concluded that the total score of the BDI-II can be used to measure depression severity in adolescent clinical samples.
IntroductionBinge eating (BE) behaviour is highly prevalent in adolescents, and can result in serious metabolic derangements and overweight in the long term. Weakened functioning of the behavioural ...inhibition system is one potential pathway leading to BE. Food cue exposure focusing on expectancy violation (CEEV) is a short intervention for BE that has proven effective in adults but has never been tested in adolescents. Thus, the current randomised pilot trial evaluates the feasibility of CEEV for adolescents and its efficacy in reducing eating in the absence of hunger (EAH) of binge food items.Methods and analysisThe trial will include N=76 female adolescents aged between 13 and 20 years with a diagnosis of bulimia nervosa, binge eating disorder (BED) or their subthreshold forms based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Participants will be randomly assigned to two sessions of CEEV or behavioural analysis (BA), a classical cognitive–behavioural therapy-based intervention. The primary endpoint is the change in EAH measured according to ad libitum consumption of personally preferred binge food in a bogus taste test at post-test based on the intention-to-treat population. Key secondary endpoints are changes in EAH of standardised binge food at post-test, in EAH at 3-month follow-up (FU) and in food craving after induction of food cue reactivity at post-test and FU. To identify further valid outcome parameters, we will assess effects of CEEV compared with BA on global ED psychopathology, BE frequency within the last 28 days, body weight, response inhibition and emotion regulation abilities. Treatment groups will be compared using analysis of covariance with intervention as fixed factor and body mass index at baseline as covariate.Ethics and disseminationThis clinical trial has been approved by the Ethics Review Committee of the Medical Association of Rhineland-Palatinate and the Medical Faculty of the Ruhr-University Bochum. The collected data will be disseminated locally and internationally through publications in relevant peer-reviewed journals and will be presented at scientific and clinical conferences. Participants data will only be published in an anonymised form.Trial registration numberDRKS00024009.
Depressive disorders are among the most prominent health problems in youth. Even with the best available pharmacological and non-pharmacological treatments, remission rates are low. Without early ...treatment, depression in youth is associated with a high risk of symptom progression, chronicity, co-morbidity, and suicidal behavior. Thus, adolescent depression is a prime candidate for innovation in treatment. In depressive adults, meta-analytic evidence has proven that bright light therapy (BLT) is a potent low-threshold intervention, promising due to easy application, low side effects, and optimized compliance. In adolescents, studies with small samples show promising effects. This randomized controlled trial will examine the effectiveness of BLT in youth inpatients.
In this randomized, controlled, double-blind multicenter parallel group trial, morning BLT is applied for four weeks in addition to treatment as usual (TAU) for depressed youth inpatients (daily morning exposure to bright light via light-emitting glasses, 10,000 lx, for 30 min) and will be compared to a control condition (placebo light treatment, red light, identical light glasses). The primary objective is to assess whether BLT reduces symptoms of depression in youth with greater effect compared to placebo light therapy. Secondary objectives are to examine the impact of BLT on responder status, application of antidepressant medication, and further depression-related symptoms (sleep, activity, quality of life, satisfaction with health, general psychopathology, alertness, and circadian function). N = 224 patients will be recruited in a naturalistic inpatient setting. A follow-up will be carried out after three and six months.
The study aims to discuss and evaluate BLT as an additive method supporting standardized clinical procedures dealing with severe to moderate depressive symptoms in youth.

Bright light therapy (BLT) has recently come into increasing focus in the treatment of adolescent depression, whereby light glasses today appear to be more feasible than light therapy boxes. This ...study investigated the feasibility and efficacy of 4 weeks of BLT with light glasses. It also analyzed whether a treatment duration of 4 weeks of BLT yields larger effects than the 2 weeks of BLT investigated in previous studies.
This first open-label, single-arm, prospective clinical trial pursued a naturalistic approach: 39 inpatients aged 12-18 years with moderate or severe depression received 4 weeks of morning BLT with light glasses in addition to usual treatment. Depressive symptoms, sleep problems, circadian phase, and the clinical global impression were assessed at several timepoints. In a second analysis, the data of the present study were compared to those from a previous pilot trial.
Depressive symptoms, sleep problems, and the global clinical impression improved significantly after BLT with light glasses, whereas the circadian phase did not change over time. Light glasses showed similarly positive effects on sleep parameters and depressive symptoms as light boxes. Contrary to expectation, prolonging BLT to 4 weeks did not yield larger effects on depressive symptoms and sleep complaints compared to 2 weeks of intervention.
Light glasses seem to be a feasible and highly acceptable method for the treatment of adolescent depression. Further randomized controlled trials are needed to obtain sufficient evidence regarding the efficacy of BLT as an add-on intervention to psychological and pharmacological approaches for adolescent depression.
Sleep, depressive symptoms and circadian preference are highly interconnected processes. Evidence suggests that, especially in adolescence, all processes should be considered in the assessment and ...treatment of patients with clinically relevant psychopathology. The SCRAM (Sleep, Circadian Rhythms, and Mood) questionnaire was developed and validated in a student sample as a promising tool to conjointly measure and separate sleep, circadian preference and depression symptomatology. The present study aims to validate a German version of the SCRAM questionnaire in an adolescent psychiatric inpatient sample. A two-step analytic strategy consisting of an exploratory factor analysis EFA followed by confirmatory factor analyses (CFA) was conducted. The EFA was run in the first half of the sample (n = 422, M = 14.92, SD = 1.67). To validate the factor structure of the EFA and the original study, two CFA`s were performed in the second half of the adolescent sample (n = 438, M = 15.07, SD = 1.68). The EFA analysis revealed a 4-factor model with 12 items. Two Sleep items and one Morningness item had cross-factor loadings. The fit indices in the CFA were good using the factor model of the original study, whereas the 4-factor model of the EFA did not converge. The German SCRAM factor model seems structurally sound in an adolescent inpatient sample, but questions remain regarding the role of diagnosis, gender, external correlates, and examining the change scores of the SCRAM scores with treatment. Before this application, further research is needed to replicate the factor structure, investigate test-retest reliability, predictive and discriminant validity and test in more generalizable samples.
