Bipolar spectrum disorder includes BP-I, BP-II, and sub-threshold BPSD. See the section of the text on Disorder Assessment for our operation definition of sub-threshold BPSD.
Substance abuse was diagnosed in both the CIDI and K-SADS with or without dependence. The CIDI assessment of substance dependence was made only among respondents who met lifetime criteria for abuse based on the finding in an early study that the prevalence of dependence without abuse is very uncommon. 12 This result has recently been called into question. 66 The K-SADS assessment of substance dependence was made with or without a history of abuse. The fact that the estimated prevalence of any substance disorder in the CIDI is identical to the estimate in the K-SADS confirms the assumption that dependence seldom occurred in the absence of a history of abuse in this sample.
