Testing Response Bias on Sensitive Topics in Self- Versus Enumerator-administered Surveys

October 31, 2022 updated by: Christopher Blattman, University of Chicago
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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Treatment
Survey respondents will self-administer three survey sections in a tablet: (1) antisocial behaviors, (2) depression symptoms, and (3) anxiety symptoms
Behavioral: Self-administered survey
Subjects will self-administer questionnaire sections on sensitive topics: (1) antisocial behaviors, (2) symptoms of depression, and (3) symptoms of anxiety.
Placebo Comparator: Control
Survey respondents will have the survey questions on the three sections administered by an enumerator
Behavioral: Enumerator-administered survey
Subjects will have enumerator-administered questionnaire sections on sensitive topics: (1) antisocial behaviors, (2) symptoms of depression, and (3) symptoms of anxiety.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The main outcome is the mean difference in survey responses for an average of the three indexes being measured
Time Frame: 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.
Through study completion, an average of 1 year
