Abstract: The Children's Play Therapy Instrument (CPTI), its development, and reliability studies are described. The CPTI is a new instrument to examine a child's play activity in individual psychotherapy. Three independent raters used the CPTI to rate eight videotaped play therapy vignettes. Results were compared with the authors' consensual scores from a preliminary study. Generally good to excellent levels of interrater reliability were obtained for the independent raters on intraclass correlation coefficients for ordinal categories of the CPTI. Likewise, kappa levels were acceptable to excellent for nominal categories of the scale. The CPTI holds promise to become a reliable measure of play activity in child psychotherapy. Further research is needed to assess discriminant validity of the CPTI for use as a diagnostic tool and as a measure of process and outcome.
