Development of Fall Risk Perception Scale for Cancer Patient:reliability and validi-ty testing
Objective To develop the Fall Risk Perception Scale for Cancer Patient and test its reliability and validity,so as to provide a valid self-assessment tool for fall prevention.Methods The scale was constructed through literature review,expert consultations and group discussion.A total of 407 inpatients with cancer were surveyed to examine the reliability and validity of the scale.Re-sults The Fall Risk Perception Scale for Cancer Patients consisted of 30 items factored into 5 dimensions:cognitive susceptibility to falls(5 items),physiological susceptibility(12 items),individual activity susceptibility(5 items),environmental susceptibility(5 items),and perceived severity of falls(3 items).The S-CVI/UA was 0.867,and the I-CVI was between 0.813-1.000.Five common factors were extracted from exploratory factor analysis,and the cumulative variance contribution rate was 66.746％.The total Cronbach's α coefficient was 0.926,and the split-half reliability coefficient was 0.672.The Cronbach's α coefficient of each dimension was between 0.914-0.970,and the split-half reliability coefficient was between 0.877-0.963.The results of confir-matory factor analysis showed that X2/df=1.845,RMSEA=0.059,GFI=0.840,CFI=0.971,NFI=0.939,AGFI=0.811,in-dicating the model fitted well.The AVE square root was significantly greater than the correlation coefficients,and there was a sig-nificant correlation among all dimensions(all P＜0.05).Conclusion The Fall Risk Perception Scale for Cancer Patient has good re-liability and validity,and can be used to assess patient's perceived risk of fall.
