Evaluation of therapeutic play: a challenge for research

There is increased pressure on practitioners offering therapy to troubled children to provide evidence of efficacy of their interventions. However, current research has not yet provided the necessary evidence. There are considerable difficulties creating a quantitative research design which excludes all relevant variables and produces unequivocal data. Quantitative research, which mainly takes the form of narrative case studies, provides ample anecdotal evidence, but there is, as yet, no comprehensive review of these data nor clear conclusions drawn. It is also necessary to consider the purpose of a narrative case study: few claim to be objective or provide a comparative analysis of a given intervention. None of the research currently available includes the opinions of experiences of children.
