| Sintesi≠ | 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. | Cronbach's alpha is a coefficient of internal consistency that quantifies the degree to which a set of items on a scale measures the same underlying construct. Introduced by Lee J. Cronbach in 1951, it remains the most widely reported reliability index in social-science, health, and educational research. |
