简要总结
Within a survey of adolescent males in Medellin schools (mainly 13-year old boys) the researchers are randomizing whether survey respondents answer sensitive questions themselves or are asked the questions by an enumerator. Questions are of three main varieties: (1) antisocial behaviors, (2) symptoms of depression, and (3) symptoms of anxiety.

结局指标
主要结局
The main outcome is the mean difference in survey responses for an average of the three indexes being measured
时间窗: Through study completion, an average of 1 year
Three survey sections are being tested: (1) antisocial behaviors, (2) depression symptoms, and (3) anxiety symptoms. Each section can be summarized by a single index of survey questions in that section--indexes of antisocial behavior, depression and anxiety. To reduce the number of hypotheses tested, the researchers plan to test the difference by treatment status for an average of these three indexes. The researchers also plan to test the mean difference by treatment status for each of the three indexes, and will report regular standard errors as well as standard errors corrected for three comparisons.
