Trends in Adolescents' Satisfaction with Their Inpatient Psychiatric Treatment: A Panel Analysis over 7 Years Because the German legislature is increasingly enabling adolescents' participation in their psychiatric treatment, we traced changes in satisfaction of 6,893 patients at the end of their stay in 10 hospitals using BEST-J. The treatments resulted in a fair overall satisfaction without any improvement over the 7 years studied. In seven hospitals, we calculated deviation from the overall satisfaction based on annual surveys.

Objectives: Study of the diagnostic performance and validity of the German Beck Depression Inventory (BDI-II) in a large data set from multiple adult samples.

Methods: The BDI-II was assessed together with the SCID-I as external criterion in 638 individuals (385 currently or remitted depressed individuals, 253 controls). The screening performance of the BDI-II was calculated for suggested cut-offs from the BDI-II manual and for optimal cut-offs derived from ROC-analyses.

In order to close this gap, the present study investigates the association between test anxiety, self-efficacy and mental images.

Background: Interest in the assessment of patient satisfaction with in-patient psychiatric treatment has steadily increased and several measurement tools are available for the quantification of patients' experience. However, they are often uni-dimensional or focus mainly on therapeutic relationship and environment, and neglect other important issues such as information about treatment and participation. The BEST questionnaires were developed as comprehensive instruments that include items on all of the mentioned topics.

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.

Background: Anxiety and depression seem to be under-recognized in their importance and are often not incorporated in subsequent prevention strategies in routine clinical care of coronary heart disease.

Methods: The KAROLA cohort included coronary heart disease patients participating in an in-patient rehabilitation program (years 1999/2000) and followed after 1, 3, 6, 8, 10, 13, and 15 years. We identified anxiety and depression trajectories based on the hospital anxiety and depression scale subdomains using joint latent class mixture time-to-event models.

Psychotherapeutic interventions share common factors, which might contribute to treatment success independent of the type of psychotherapy. Previous research on common factors of psychotherapy was mostly conducted in outpatients and covered the development of common factors throughout a therapy over months or years. However, the role of common factors for the psychotherapeutic treatment success in inpatients during their hospital stay has not been addressed so far.

Dysfunctional posttraumatic cognitions seem to play an important role in adjustment after traumatic experiences. However, little research has been done on maltreated children and adolescents. Furthermore, possible causal associations between cognitions, posttraumatic stress symptoms, and internalizing and externalizing problems have rarely been investigated.

Background: It has been shown that positive treatment expectancy (TE) and good working alliance increase psychotherapeutic success in adult patients, either directly or mediated by other common treatment factors like collaboration. However, the effects of TE in psychotherapy with children, adolescents and their caregivers are mostly unknown. Due to characteristics of the disorder such as avoidant behavior, common factors may be especially important in evidence-based treatment of posttraumatic stress symptoms (PTSS), e.

Hence, including nonoffending parents in trauma-focused cognitive-behavioral therapy (TF-CBT) for children and adolescents may help both children and their parents to cope with the trauma. Up to now, three randomized controlled trials have investigated parental depressive symptoms after TF-CBT.

There are only few studies on latent trajectories of body mass index (BMI) and their association with diabetes incidence and mortality in adults.We used data of the Vorarlberg Health Monitoring & Prevention Program and included individuals (N=24,875) with BMI measurements over a 12-year period. Trajectory classes were identified using growth mixture modeling for predefined age groups (<50, 50-65, >65 years of age) and men, women separately.

Background: To evaluate whether the symptoms of children and adolescents with clinically significant posttraumatic stress symptoms (PTSS) form classes consistent with the diagnostic criteria of complex PTSD (CPTSD) as proposed for the ICD-11, and to relate the emerging classes with treatment outcome of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT).

Methods: Latent classes analysis (LCA) was used to explore the symptom profiles of the clinical baseline assessment of N = 155 children and adolescents participating in a randomized controlled trial of TF-CBT. The treatment outcomes of patients with posttraumatic stress disorder (PTSD) and of patients with CPTSD were compared by a t-test for depended samples and a repeated-measures ANOVA.

Since an important goal of the youth welfare system is to prevent troubled adolescents from committing acts of delinquency in future, professional caregivers need to possess accurate knowledge about past behaviors in order to implement appropriate interventions. As part of a comprehensive study on youth in state care, adolescents at 30 residential care facilities in Switzerland were surveyed about past acts of delinquency, and their responses were compared to those of their professional caregivers to see how well they correlated. A sample of 267 male and female adolescents aged 11-18years completed questionnaires about the frequency, nature, and seriousness of different types of offenses, while a designated caregiver for each resident completed a corresponding questionnaire.
