This report describes the first module of the "First Steps" program, an early intervention program for at-risk kindergartners who show the early signs of antisocial behavior patterns. This module presents four options for screening and identifying kindergarten students at risk for antisocial behavior patterns. In option one, the kindergarten teacher is given a definition of antisocial behavior and asked to nominate children whose characteristic behavior patterns reflect antisocial behavior. Nominated children are then rank-ordered by the teacher according to how well their behavior matches the definition. Option two also relies upon teacher nominations and rank-ordering of at-risk students, but also requires the teacher to rate the highest ranked students on a nine-item scale. In option three, a brief, economical rating procedure is used in which the teacher rates all students in the class on a set of behavioral criteria that are strongly associated with antisocial behavior patterns. The last option uses a multiple gating procedure containing three interrelated screening stages (teacher nominations and rank ordering, teacher and parent ratings of child behavior, and direct observations) for identifying likely candidates for First Steps. Each option description is followed by detailed instructions. Appendices include relevant forms and a rating scale. (CR)
