periods. The remaining 2 items (physical fights and telling lies), which occurred with higher frequency, were assessed only for the period prior to age 15 years, using 4 response options (never, rarely, sometimes, and often). The response rate for 1 SRQ item (robbed or mugged someone) was so low in the current sample that it was omitted from the analysis. Thus, the reported results focus on 10 CD criteria, for which short descriptions are seen in the Figure. We evaluated the test-retest reliability of these items (n=298; mean interassessment interval, 4.8 weeks), and for most of them, they were in the acceptable to good range. By weighted κ,18 the range was +0.42 (starting physical fights) to +0.76 (playing hooky) with a mean of +0.62. By polychoric correlation, the range was +0.65 (starting fights) to +0.93 (running away) with a mean of +0.81.
