The purpose is for the research team to obtain feedback on the modification process prior to implementing the measure to approximately 1800 students across 11 middle schools in during the third and final year of the larger study. The process of the development of the ECA-M8 is outlined and the preliminary item analysis results are reported for the multiple-choice portion of the assessment.
