This study examined the effectiveness of child centered play therapy (CCPT) with academically at-risk 1st graders. In this quasi-experimental design, twenty-one 1st grade students were assigned to the experimental group and 20 students were assigned to the no treatment control group. The children in the experimental group received two 30 minute play therapy sessions per week for the duration of eight weeks. Three hypotheses were analyzed. A two-factor repeated measures analysis of variances (SPANOVA) were performed on each dependent variable to determine if the experimental group performed differently from the control group across time according to the pretest and posttest results of the Young Child's Achievement Test (YCAT), the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PSPCSAYC), and the Student-Teacher Relationship Scale (STRS). Additionally, partial [eta]2 was calculated to determine practical significance. One hypothesis was retained at the 0.05 level of significance. Findings indicated that academically at-risk 1st graders who participated in CCPT scored statistically significant higher on academic achievement. Specifically, children assigned to the experimental group demonstrated a statistically significant increase in Early Achievement Composite (p = 0.03) when compared to children assigned to the no treatment control group. No statistical significant results were found on Self-Concept and Student-Teacher Relationship Stress. [The dissertation citations contained here are published with the permission of ProQuest LLC.
