Brief summary
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.
Interventions
BEHAVIORALSelf-administered survey
Subjects will self-administer questionnaire sections on sensitive topics: (1) antisocial behaviors, (2) symptoms of depression, and (3) symptoms of anxiety.
BEHAVIORALEnumerator-administered survey
Subjects will have enumerator-administered questionnaire sections on sensitive topics: (1) antisocial behaviors, (2) symptoms of depression, and (3) symptoms of anxiety.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The main outcome is the mean difference in survey responses for an average of the three indexes being measured | 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. |
