This program is delayed; we do not expect that we will distribute the TAS-45 until late 2011 or 2012, we will be collecting data for additional validation studies of the trilemma method. We apologize for any inconvenience.
Toddler Attachment Sort (TAS-45) is a brief observational tool with a software scoring system, developed in New Zealand by Dr. John Kirkland. It is used for measurement of attachment behaviors of parent/child (18-36 months) relationships in research projects and for guiding clinical work with families. Field tested on the Early Childhood Longitudinal Study, Birth Cohort sample of 8,750 two year olds. Not yet released, date to be announced.
