Approximately one-third of stroke survivors have symptoms of depression. A better understanding of the early risk factors implicated in this form of comorbidity may contribute to the development of early prevention strategies and to improving outcomes for this population. The current study uses ecological momentary assessment techniques to identify behavioral risk factors for depression 3 months after stroke. Thirty-six participants completed ambulatory monitoring of daily life circumstances (location, social environment, and activity) 5 times per day during a 1-week period after hospital discharge. Clinician-administered measures of depression were also provided before discharge and 3 months later. Ambulatory monitoring revealed that depression scores at 3 months were lower among individuals with more social interactions but higher among those who reported having sports activities and working in the week following hospital discharge. Daily life behaviors may have important implications for understanding the risk of poststroke depression, and mobile technologies may provide important contributions to their investigation.

Background: Recognition of symptoms of Social anxiety (SA) may be difficult among individuals with Autism Spectrum Disorders (ASD) because of overlap between social anxiety and autistic symptomatology. The main aim of our study was thus to explore the association between symptoms of social anxiety and clinical characteristics of ASD in order to identify individuals experiencing concomitant ASD and social anxiety disorder. We also described the prevalence of SA in a sample of children and adolescents with ASD. Method: 79 children and adolescents with ASD (with and without intellectual disability) and 28-matched control participants were recruited in two French Expert Centers for ASD, coordinated by the Fundation FondaMental. Psychiatric comorbidities, anxiety disorders and depression were screened with standard tools (Liebowitz social anxiety scale, Hamilton Depression and Anxiety Rating Scale) and correlated to autistic features and social skills assessed with the social responsiveness scale 2 (SRS-2) and the repetitive behavior scale (RBS-R). We performed bivariate analysis between the social anxiety level and the scores measured with different clinical scales. We then adjusted the observed relationships with the alterations of SRS-2 and RBS-R scores. Results: After adjustment, the level of social anxiety appeared as significantly associated with alterations in social reciprocity and particularly with the SRS-2 "social communication" and "social motivation" sub-scores, but not with RBS-R score. Conclusions: We confirm previous reports showing that individuals with ASD are at high risk for specific anxiety disorders. In particular, high levels of impairments in social motivation and
