Effectiveness can be measured both qualitatively and quantitatively (see Testimonials). The referrer and or the parent complete a questionnaire that indicates some of the child’s strengths and difficulties. These questionnaires are completed before, during and after the therapy. They monitor changes that take place and indicate the outcomes of the play therapy.
- Between 74% and 83% of children receiving play therapy delivered to PTUK/PTI standards, show a positive change.
- The more severe the difficulties, the greater the percentage of children showing a positive change.
- The younger the child, the greater the percentage of children showing a positive change: 80% at age 6, 71% at age 12.
