We describe validation of a COVID-19 antibody test for detection of anti-SARS-CoV-2 receptor-binding domain (RBD) IgG antibodies in blood plasma utilizing ethically sourced reagents not derived from aborted fetal cell lines.

Why Haven't You Texted Me Back? Adolescents' Digital Entrapment, Friendship Conflict, and Perceived General Health.

Objective: Many adolescents feel pressure to be constantly available and responsive to others via their smartphones and social media. This phenomenon has been understudied using quantitative methods, and no prior study has examined adolescents' specific stress about meeting digital availability expectations within a best friendship, or entrapment. The present study offers an important preliminary examination of this unique digital stressor in a developmental context by examining prospective associations between digital entrapment, psychosocial adjustment, and health in adolescence.

Age-related differences in social media use, online social support, and depressive symptoms in adolescents and emerging adults.

Background: Despite growing concerns about the impact of social media use on the developing brain and associated mental health impacts, whether susceptibility to the benefits and harms of social media use changes across adolescence and young adulthood has yet to be empirically tested.

Method: Using a cross-sectional sample of participants aged 14-22 years (N = 254), we examined (a) linear and non-linear age-related changes in social media use and online social support and (b) age-related differences in the effects of social media use and online social support on depressive symptoms.

Results: We found age differences in social media use, but not online social support, such that social media use increased across adolescence and peaked around age 20, followed by stable use into young adulthood.
