The Children’s Developmental Play Instrument (CDPI): An Extended Validity Study

Saralea E. Chazan, Ph.D. and Yana A. Kuchirko, M.A.

This is an extended construct validity study of the Children’s Developmental Play Instrument (CDPI), a multidimensional scale to measure play activity among mainstream children based on the psychoanalytic concepts of coping and defensive strategies. The sample included 160 children. Ten-minute videotapes were collected of children between the ages of 1.3 years and 8.5 years at play. The foci of this extended study were six “core” variables comprising the functional level of the CDPI consisting of the following scales: play engagement, symbolic functioning, adaptive play style, inhibited/conflicted play style, impulsive/aggressive play style, and disorganized play style. Good to excellent reliability was achieved by ratings of two independent raters. Regression analysis revealed the five predictors, as a set, were very strong correlates of adaptive play style. Component analysis reduced the six core functional variables to two components clarifying the relationships between the six core variables as organized along two continuums. One continuum is discussed to briefly illustrate the structure of play styles reflected in the play activity of one child.
