A studying patients with leukemia admitted in other hospitals at the same time was not possible. Based on the limitations of this study, including the small number of subjects, applying the study only in one hospital, and in only one section, and the problems of generalize ability, it is recommended for further similar studies to be conducted in other hospitals with larger sample size. Also, to improve the quality of data analysis, it is suggested that in future, researches with similar methodology using multivariate tests also must be considered. Anxiety, irritability, worries, depression, and aggression were also sometimes a barrier to communicate with the patients and for them to complete the questionnaire. It should be noted that the approximate time to enter the study for this number of subjects (n = 49) was 3 months. Another limitation was the limited environment of the study; due to this limitation, studying patients with leukemia ad mitted in other hospitals at the same time was not possible.
