This methodology report documents the design, development, and psychometric characteristics of the assessment instruments used in the second wave of the ECLS-B. The assessment instruments discussed measure children's cognitive development (BSF-R), socioemotional functioning (Two Bags Task), security of attachment (TAS-45), and physical development (height, weight, middle upper arm circumference (MUAC), and head circumference). The report also includes information about interviewer observations of the child and the child's environment, as well as indirect assessments of the children through questions in the parent interview. Following an introductory chapter, Chapter 2 presents a discussion of the decision to include a direct assessment of children's developmental status, the BSID-II, and the adaptation of the 18-month and 30-month shortened versions of that assessment for use at 2 years. Chapters 3 and 4 describe the work that was done to develop the BSF-R and the Item Response Theory (IRT) analyses conducted with the longitudinal dataset (i.e., combined 9-month and 2-year BSF-R scores). Chapter 5 describes the BSF-R scores included on the longitudinal 9-month-2-year data file. The Two Bags Task---the observational measure of the videotaped parent-child interaction---is summarized in chapter 6, and children's physical measurements are summarized in chapter 7. Chapter 8 discusses the work that was done to develop the TAS-45--a shortened version of the Attachment Q-Sort--and summarizes scores obtained, and the procedures for training interviewers and maintaining reliability during the year of data collection. Chapter 9 summarizes the remaining observation items that were completed by the interviewer in CAPI after the home visit was completed, including the interviewer observations of child behavior during the BSF-R, and the child's home environment. Chapter 10 summarizes the indirect assessments of the child in the parent CAPI instrument, including the toddler word list, developmental milestones, and children's self-regulatory skills. Finally, a table of the direct child assessment intercorrelations is presented in Appendix A and the Toddler Attachment Sort Items are presented in Appendix B. Throughout this report, a brief review of key features of the 9-month assessments relevant to the 2-year measures is included when warranted. (Contains 58 tables, 59 figures, and 12 exhibits.)
