Development of an assessment scale of hypothermia risks for caesarean section and its test of validity and reliability
Objective To construct a hypothermia risk assessment scale for cesarean section and verify its reliability and validity.Methods The initial risk assessment scale of hypothermia risks for caesarean section was constructed through literature analysis and expert consultation.Data from 158 cesarean section women were collected and the reliability and validity of the scale were tested.Results The constructed scale included 14 first-level items and 16 second-level items.Exploratory factor analysis extracted 4 common factors,with a cumulative variance contribution rate of 59.050％;The load values of each item in its common factor range from 0.451 to 0.764;The correlation coefficient of the criterion(tympanic membrane temperature)was 0.815,and the area under the ROC curve for predicting hypothermia in cesarean section women was 0.968.The 95％confidence interval was 0.926-1.010(P＜0.001),and the Cronbach's α coefficient of the scale was 0.763.Conclusion The intraoperative hypothermia risk assessment scale for cesarean section has good reliability and validity,and can be used as an auxiliary tool for clinical assessment of hypothermia risk for caesarean section.
