If treatment influences survey responses, it biases experimental estimates. We develop a validation technique that uses intensive qualitative work to assess survey measurement error. Subjects were assigned to receive cash, therapy, both, or neither. According to survey responses, receiving both treatments dramatically reduced crime and other sensitive behaviors. Local researchers spent several days with a random subsample of subjects following their endline surveys, building trust and seeking verbal confirmation of six behaviors: theft, drug use, homelessness, gambling, and two expenditures. This validation suggests that subjects in the control and cash only ...
