T1  - Actigraphy-derived sleep profiles of children with and without attention-deficit/hyperactivity disorder (ADHD) over two weeks — comparison, precursor symptoms, and the chronotype
JF  - Brain Sciences
N2  - Although sleep problems are common in children with ADHD, their extent, preceding risk factors, and the association between neurocognitive performance and neurobiological processes in sleep and ADHD, are still largely unknown. We examined sleep variables in school-aged children with ADHD, addressing their intra-individual variability (IIV) and considering potential precursor symptoms as well as the chronotype. Additionally, in a subgroup of our sample, we investigated associations with neurobehavioral functioning (n = 44). A total of 57 children (6–12 years) with (n = 24) and without ADHD (n = 33) were recruited in one center of the large ESCAlife study to wear actigraphs for two weeks. Actigraphy-derived dependent variables, including IIV, were analyzed using linear mixed models in order to find differences between the groups. A stepwise regression model was used to investigate neuropsychological function. Overall, children with ADHD showed longer sleep onset latency (SOL), higher IIV in SOL, more movements during sleep, lower sleep efficiency, and a slightly larger sleep deficit on school days compared with free days. No group differences were observed for chronotype or sleep onset time. Sleep problems in infancy predicted later SOL and the total number of movements during sleep in children with and without ADHD. No additional effect of sleep problems, beyond ADHD symptom severity, on neuropsychological functioning was found. This study highlights the importance of screening children with ADHD for current and early childhood sleep disturbances in order to prevent long-term sleep problems and offer individualized treatments. Future studies with larger sample sizes should examine possible biological markers to improve our understanding of the underlying mechanisms.

T1  - EEG data quality: determinants and impact in a multicenter study of children, adolescents, and adults with attention-deficit/hyperactivity disorder (ADHD)
JF  - Brain Sciences
N2  - Electroencephalography (EEG) represents a widely established method for assessing altered and typically developing brain function. However, systematic studies on EEG data quality, its correlates, and consequences are scarce. To address this research gap, the current study focused on the percentage of artifact-free segments after standard EEG pre-processing as a data quality index. We analyzed participant-related and methodological influences, and validity by replicating landmark EEG effects. Further, effects of data quality on spectral power analyses beyond participant-related characteristics were explored. EEG data from a multicenter ADHD-cohort (age range 6 to 45 years), and a non-ADHD school-age control group were analyzed (n\(_{total}\) = 305). Resting-state data during eyes open, and eyes closed conditions, and task-related data during a cued Continuous Performance Task (CPT) were collected. After pre-processing, general linear models, and stepwise regression models were fitted to the data. We found that EEG data quality was strongly related to demographic characteristics, but not to methodological factors. We were able to replicate maturational, task, and ADHD effects reported in the EEG literature, establishing a link with EEG-landmark effects. Furthermore, we showed that poor data quality significantly increases spectral power beyond effects of maturation and symptom severity. Taken together, the current results indicate that with a careful design and systematic quality control, informative large-scale multicenter trials characterizing neurophysiological mechanisms in neurodevelopmental disorders across the lifespan are feasible. Nevertheless, results are restricted to the limitations reported. Future work will clarify predictive value.

T1  - Freiheitsentziehende Maßnahmen in bayerischen Heimeinrichtungen für Kinder, Jugendliche und junge Volljährige mit Intelligenzminderung
JF  - Zeitschrift für Kinder- und Jugendpsychiatrie und Psychotherapie
N2  - Fragestellung: In Bayern leben etwa 10 % aller jungen Menschen mit Intelligenzminderung in Heimeinrichtungen. 2016 wurde in Presseberichten der Vorwurf unzulässiger freiheitsentziehender Maßnahmen formuliert. Im Rahmen des Projekts REDUGIA wurde in bayerischen Heimeinrichtungen eine repräsentative Erhebung zu freiheitsentziehenden Maßnahmen (FeM), herausforderndem Verhalten (hfV) und der Mitarbeiterbelastung (MaB) durchgeführt. Methodik: 65 Einrichtungen für junge Menschen mit Intelligenzminderung in Bayern wurde ein Fragebogen zu strukturellen Gegebenheiten sowie MaB, hfV und FeM zugesendet. Neben deskriptiven Auswertungen wurden korrelative Analysen bzw. Regressionsanalysen zum Zusammenhang zwischen hfV, FeM und MaB durchgeführt. Ergebnisse: Es wurden Daten zu 1839 Personen in 61 Einrichtungen erhoben. 84.3 % der Einrichtungen berichteten geringe Raten an hfV und FeM, während 15.7 % ein gehäuftes Vorkommen von hfV und FeM angaben. Auf n = 1809 Vollzeitäquivalente kam es innerhalb von 14 Tagen zu 639 körperlichen Angriffen durch Bewohner_innen. In 12 Monaten wurden problemverhaltensassoziiert 85 Krankmeldungen sowie 33 Versetzungsanträge/Kündigungen berichtet. Es zeigte sich ein signifikant positiver Zusammenhang zwischen hfV und FeM (R² = .307, F = 21.719, p < .001). Die Mitarbeiterbelastung korrelierte positiv mit hfV (r = .507, p < .001). Schlussfolgerungen: Die Studienbefunde weisen darauf hin, dass hfV sowie FeM bei jungen Menschen mit Intelligenzminderung kein flächendeckendes Phänomen darstellen, sondern sich auf wenige spezialisierte Einrichtungen fokussieren. Mögliche Maßnahmen zur Prävention von Problemverhalten und Freiheitsentzug werden diskutiert.
N2  - Objective: In Bavaria, around 10 % of youths with an intellectual disability (ID) live in residential facilities. In 2015, media raised accusations of inadmissible use of coercive measures. The REDUGIA project carried out a representative survey in Bavarian facilities regarding coercive measures (FeM), challenging behavior (hfV), and employee stress (MaB). Method: We sent a questionnaire concerning structural conditions, MaB, hfV and FeM to 65 Bavarian facilities for young people with ID. In addition to preparing descriptive evaluations, we performed correlative and regression analyses concerning the relationship between hfV, FeM, and MaB. Results: We retrieved data from 1,839 subjects in 61 facilities. 84.3 % of facilities reported low rates of hfV and FeM, while 15.7 % reported an increased incidence of hfV and FeM. For n = 1809 full-time position equivalents there were 639 physical attacks by residents over the course of 14 days. We observed 85 instances of sick leave and 33 transfer apllications/resignation associated with hfV. The frequency of hfV predicted the frequency of FeM (R² = 0.307, F = 21.719, p < .001). MaB correlated positively with hfV (r = 0.507, p < .001). Conclusions: The descriptive data indicate that hfV and FeM are not general phenomena but occur mainly in a circumscript number of highly specialized facilities. This emphasizes the need for prevention of hfV and FeM.
