Validation metrics applied when self-reported measures provide the reference standard (adapted from9)
| Term | Definition | Formula |
| Sensitivity | The proportion of individuals who truly were mistreated (reported mistreatment) who were classified as mistreated by observation. | A/(A+C) |
| Specificity | The proportion of individuals who truly were not mistreated (reported no mistreatment) who were classified as not mistreated by observation. | D/(B+D) |
| Percent agreement | The proportion of agreement between observation and self-report among the total sample. | (A+D)/(N) |
| Inflation factor | Ratio of observed mistreatment to true (self-reported) mistreatment. | (A+B)/(A+C) |
