Protection of Human Participants

• Identify the benefits and risks of participation addressed by the authors. Were there benefits or risks the authors do not identify?

The subjects of the quantitative study were children who had undergone hematopoietic stem cell transplantation, "an intensive therapy used to improve survivorship and cure various oncologic diseases.

The participants had already elected to go through the procedure before the study began.

• Was informed consent obtained from the subjects or participants?

Consent was obtained from the legal guardians; the children were not cognitively impaired and the children had to give their verbal agreement to participate (Chamorro-Vina 2012: 4).

• Did it seem that the subjects participated voluntarily in the study?
