Contemporary Research on Child-Centered Play Therapy (CCPT) Modalities: A Meta-Analytic Review of Controlled Outcome Studies
Description: The present meta-analytic study estimated the overall effectiveness of child therapy interventions using CCPT methodology and explored the relationships between study characteristics and treatment effects. Fifty-two studies between 1995 and the present were included based on the following criteria: (a) the use of CCPT methodology, (b) the use of control or comparison repeated measure design, (c) the use of standardized psychometric assessment, and (d) clear reports of effect sizes or sufficient information for effect size calculation. Hierarchical linear modeling (HLM) techniques were utilized to estimate the overall effect size for the collected studies and explore relationships between effect sizes and study characteristics. Dependent variable included 239 effect sizes, and independent variables included 22 study characteristics. The mean age of all child participants in the collected studies was 6.7. In 15 studies, the majority of participants were Caucasian. An equal number of studies were made up of non-Caucasian participants, including 3 with majority African American, 4 with majority Hispanic/Latino participants, 5 with majority Asian/Asian American participants, and 3 with other ethnic populations. Study collection included 33 studies with majority of boys and 11 studies with majority of girls. HLM analysis estimated a statistically significant overall effect size of 0.47 for the collected studies (p < 0.001). This result indicated that the overall improvement from pre to post treatment demonstrated by children in experimental groups was approximately 1/2 standard deviation better than by children in control groups. A statistically significant amount (49.2%) of between-study variance was found (p < 0.001), indicating the heterogeneity among the 52 studies Statistically significant relationships were found between effect sizes and study characteristics including child age, child ethnicity, clinical level of referral, treatment integrity, presenting issue, source of data, population, and caregiver involvement. Effect size findings for CCPT and its moderators should be interpreted in light of ...
