Laboratory and performance-based measures of depression in children and adolescents.

Reviews laboratory and performance-based measures for the assessment of symptoms and correlates of depression in children and adolescents. First, we briefly review limitations of self-report and other report measures of depression. Next, we describe four laboratory methods, including social interaction tasks, information-processing tasks, measures of psychological deficits and laboratory analogue designs, and sleep studies. We then summarize the specific depressive symptoms measured by each of these methods. Finally, we discuss issues of the validity and utility of these methods.
