Play is regarded as a child's primary occupation and provides valuable information about the child's abilities. Thus, informative assessment tools of play skills are critical for establishing play-related treatment goals in occupational therapy. The objective of this study is to present a practical method for occupational therapists to develop intervention goals using the Yonsei-Social Play Evaluation Tool (Y-SPET) keyforms. Parent responses (n = 310) for preschool children (three to six years old) who did not have a medical diagnosis were examined. The Rasch measurement model was used to create keyforms for the Y-SPET. All children's raw scores were converted into individual Rasch-calibrated logit scores and standard errors were estimated to establish logically attainable treatment goals. Results showed use of the keyforms could logically identify the intervention goals of the children's social play. This suggests that the Y-SPET keyforms are helpful for assessing the level of children's social play and establishing practical treatment goals.
