This user-friendly manual guides professionals through the process of administering, scoring, and interpreting the Communication and Symbolic Behavior Scales (CSBS™), one of the best measures of early communication in children 8–24 months (or up to 72 months if developmental delays are present).

The manual includes:

a concise question-and-answer introduction to CSBS™

informative summaries that reveal how the communication and symbolic behavior scales were developed

detailed, easy-to-follow instructions on how to administer the Caregiver Questionnaire, conduct each part of the videotaped Behavior Sample, and interpret the behaviors on the videotape

clear guidelines on rating, summarizing, and interpreting scores

technical data about CSBS™, including information about standardization, scaling and norming, reliability, and validity

helpful tips on planning individualized interventions

Filled with tables, charts, and checklists that summarize key points, clarify technical data, and help users organize the information and material they need, this manual will make it easier for professionals to use CSBS™ effectively with the children and families they serve.

This manual is part of CSBS™, a norm-referenced, standardized tool that uses parent interview and direct observation to assess infants, toddlers, and preschoolers at risk for communication delays and impairments. With 22 rating scales that accurately survey children's language skills and symbolic development, CSBS is backed by technical data and compatible with most developmental curricula in use today.
