Summary	A self-report delinquency (SRD) scale measures offending by asking respondents directly how often they have committed specific delinquent or criminal acts, rather than relying on arrests or convictions. The modern frequency-based approach was established by Delbert Elliott and Suzanne Ageton in 1980 for the National Youth Survey, designed to capture the full range and frequency of offending and to overcome the biases of official crime records.	The criminal career paradigm is a framework for studying offending as a longitudinal sequence in an individual's life rather than as undifferentiated aggregate crime. Codified by Blumstein, Cohen, Roth, and Visher in the 1986 National Academy of Sciences report, it decomposes crime into distinct dimensions — whether someone offends (participation), how often active offenders offend (frequency, λ), and the onset, seriousness, and duration of the career — each potentially with different causes.
