This study explores differences in the out-of-home behavior of community-dwelling older adults with different cognitive impairment. Three levels of complexity of out-of-home behavior were distinguished: (a) mostly automatized walking behavior (low complexity), (b) global out-of-home mobility (medium complexity), and (c) defined units of concrete out-of-home activities, particularly cognitively demanding activities (high complexity). A sample of 257 older adults aged 59 to 91 years (M = 72.9 years, SD = 6.4 years) included 35 persons with early-stage Alzheimer's disease (AD), 76 persons with mild cognitive impairment (MCI), and 146 cognitively healthy persons (CH). Mobility data were gathered by using a GPS tracking device as well as by questionnaire. Predicting cognitive impairment status by out-of-home behavior and a range of confounders by means of multinomial logistic regression revealed that only cognitively demanding activities showed at least a marginally significant difference between MCI and CH and were highly significant between AD and CH.

This study explores the relationship between out-of-home behavior and daily mood of community-dwelling older adults with different levels of cognitive impairment across four consecutive weeks. The sample included 16 persons with early stage Alzheimer's disease (AD), 30 persons with mild cognitive impairment (MCI), and 95 cognitively healthy persons (CH). Using a multi-method approach, GPS tracking and daily-diary data were combined on a day-to-day basis. AD and MCI adults showed lower mood than the CH group. Whereas stronger positive links between mood and out-of-home behavior were found for AD compared to the total sample on an aggregate level, predicting daily mood by person (i.e., cognition) and occasion-specific characteristics (i.e., mobility and weekday), using multilevel regression analysis revealed no corresponding effect. In conclusion, cognitive status in old age appears to impact on mobility and mood as such, rather than on the mood and out-of-home behavior connection.

The impact of school-closings on adolescents’ mental health and well-being in the management of the ongoing COVID-19 pandemic is subject to ongoing public debate. Reliable data to inform a balanced discussion are limited. Drawing on a large ongoing multi-site project in Germany, we assessed differences in self-reported psychopathology in a matched convenience-sample of adolescents assessed pre- (November 26, 2018 to March 13, 2020; n = 324) and post the first lockdown (March 18, 2020 to August 29, 2020; n = 324) early 2020 in Germany. We found no evidence for an increase in emotional and behavioral problems, depression, thoughts of suicide or suicide attempts, eating disorder symptoms, or a decrease in general health-related quality of life. Reported suicide plans significantly decreased from 6.14 to 2.16%. Similarly, conduct problems decreased in the post-lockdown period. Family risk-factors did not moderate these findings. The influence of socioeconomic status on emotional and behavioral problems as well as depression decreased during the lockdown. Based on the present findings, the first school-closing in Germany had no immediate and severe impact on adolescents’ well-being. However, caution is warranted as our data covers a fairly small, affluent sample over a limited time-span and long-term consequences cannot be ruled out.

Referring to ICD-10 based diagnostic criteria and consequently avoiding confusing problem behaviour with mental disorders, point prevalence of mental disorders was lower than in the general population. A systematic deficit in meeting mental health problems in adults with ID indicates the need for implementing strategies to maximise the quality of identification and management of mental disorders.
