RESUMO
Background: Studies measuring hair cortisol concentration (HCC) have been increasingly conducted to document stress-related, endocrine changes aggregated over time. Previous studies have shown that HCC reflects abnormalities in the hypothalamic-pituitary-adrenocortical axis (HPA axis) in the context of somatic diseases, such as Cushing's syndrome. HCC variations also reveal a corresponding alteration in HPA-axis-function in mental disorders, highlighting its potential role as a biomarker for interventions targeting mental health problems. Aims: The aim of this study was to investigate the role of HCC in various psychological and neuropsychiatric interventions and to explore the extent to which HCC can serve as a predictive or outcome parameter in such interventions by conducting a PRISMA-compliant review of the literature. Methods: From May to July 2022, the databases Web of Science, Google Scholar, PsychINFO, and ResearchGate were systematically searched using different combinations of relevant keywords. Studies of different types that examined HCC in the context of a wide range of psychological and neuropsychiatric interventions were included. Studies in languages other than English or German and animal studies were excluded. The MMAT tool was used, to assesses the Risk of bias. Results: The initial search identified 334 studies. After applying the inclusion and exclusion criteria, 14 publications with a total number of 1,916 participants were identified. An association between HCC and PTSD, depressive disorders, and ongoing social and family stress can be documented. The effect of relaxation techniques, mental training, CBT, or PTSD therapy on HCC has been studied with equivocal results. Some studies found decreased HCC after treatment, while others did not show a clear effect. Baseline HCC appears to be of particular importance. In some studies, higher baseline HCC was associated with increased treatment response, providing a predictive value for HCC. Discussion: HCC is increasingly being used as a biomarker for the mapping of psychological and neuropsychiatric interventions. However, due to the wide range of study populations and interventions, results are still heterogeneous. Nevertheless, HCC seems to be an encouraging biological parameter to describe the trajectory of different interventions aimed at improving mental health.
RESUMO
Introduction: Multidimensional pediatric-psychosomatic inpatient treatment should be considered a highly relevant concept in the German healthcare system. This treatment concept has been successfully integrated to support youth with mental disorders and patients with chronic somatic conditions. Studies on treatment impact and empirical evidence of pediatric-psychosomatic inpatient therapies are rare, despite their clinical significance. Therefore, the study aims to provide initial indications of what constitutes to enhanced treatment effectiveness by comparing two different pediatric-psychosomatic inpatient treatment concepts. The clinics are comparable regarding the treated disorders, which include: dissociative, mood, and somatoform disorders, and psychological factors associated with chronic somatic conditions. Multidimensional treatment in both clinics include components of individual and family therapy, along with group-, art-, music-, creative-, and physio-therapy. Both clinics differed regarding their treatment philosophy in which; Clinic A practiced psychodynamic behavioral elements more strongly, while Clinic B rooted itself more strongly with psychoanalysis and family-dynamic practices. Method: Each clinic recruited 25 patients for the study. They completed two questionnaires both at admission and discharge, which measured general behavioral and emotional problems (YSR); and, respectively, difficulties in emotion perception and processing (TAS-26). The effectiveness of the treatment was examined by conducting one-sample t-test and effect sizes for each clinic. To obtain information on differentiating treatment effects, mixed ANOVAs were calculated. For estimating its influence, the treatment duration was taken into account as a covariate calculating an ANCOVA. Results: In both settings, treatment effects can be observed regarding internalizing problems. For alexithymia, no effects were seen in Clinic B, while in Clinic A, there was a significant reduction. When comparing both clinics, the ANOVAs showed significant interaction effects displaying advantages for Clinic A in the reduction of internalizing, total behavioral problems and alexithymia. Taking into account the treatment duration as a covariate, those effects level out. Significant differences between the clinics were no longer statistically detectable. Discussion: The present study provides substantial preliminary indications on the effectiveness of multidimensional pediatric-psychosomatic inpatient therapy, which seems suitable for alleviating the general symptom burden and problems by identifying and processing emotions. Furthermore, the results indicate that an extended treatment duration may contribute to more pronounced effects.
