Schmidt, Louis A.; Miskovic, Vladimir; Boyle, Michael; Saigal, Saroj – Child Development, 2010
The authors examined internalizing behavior problems at middle childhood, adolescence, and young adulthood and brain-based measures of stress vulnerability in 154 right-handed, nonimpaired young adults (M age = 23 years): 71 (30 males, 41 females) born at extremely low birth weight (ELBW; less than 1,000 g) and 83 (35 males, 48 females) controls…
