Samples were only taken from The Harvesting Hope Program in Aurora IL. As a result, the sample cannot be a representation of the rest of the child homeless population. Homeless children in other programs may produce differing results. Also, using the intervention in another geographical setting does not ensure its effectiveness in that setting.
The second limitation to this study is the sample size. The sample consists of 40 children in The Harvesting Hope Program. With such a small sample one cannot come to a general conclusion about the effectiveness of Play Therapy on children's behaviors. A larger sample size would be required in order to draw a general and more accurate conclusion.
The third limitation to the study is the time constraint of the survey. The participants were given a very limited amount of time to complete the survey. Participants who experience difficulties with time constraints will be less likely to respond to a survey with such limitations because they do not have the time to complete it. Also, in a survey, the participants are forced to respond based on the categories that are present, which limits the range of responses. Unlike an interview where the participants may ask clarifying questions, in a survey the participants seek direction from the survey on how to complete it and where to
