What type of survey is particularly useful for measuring crimes such as drug usage?

The self-report survey is particularly useful for measuring crimes such as drug usage because it relies on individuals' personal accounts of their behavior, providing direct insights into activities that may not come to the attention of law enforcement officials. This method allows respondents to disclose their drug use anonymously, which can yield more accurate and comprehensive data. People are often reluctant to admit to illegal behaviors or drug use in official reports or interviews with authority figures for fear of legal consequences. Therefore, self-report surveys can capture information on sensitive topics, such as substance use, that might be underreported in formal crime statistics. This type of survey is valuable in understanding the prevalence and patterns of drug use within various populations, contributing to a more nuanced understanding of juvenile delinquency related to drug-related offenses.
