Abstract
  • The purpose of the study is to examine differential item functioning when moving from an Academic setting to a community setting, differential item functioning when extracting ten items in a community setting, and comparative diagnostic efficiency of the extracted items to the embedded items. Differential item functioning using Samejima's Graded Response Model indicated that across samples, total observed scores were similar across levels of mania. ROC indicated that the ten extracted items discriminated well. Sum scores less than 18 substantially decreased the probability of bipolar disorder, while sum scores greater than 18 substantially increased the probability of bipolar disorder in youth. Findings suggest that the extracted items perform similarly to the embedded items in the community setting.
