ABSTRACT
Objective To prepare the Elderly Functional Constipation(FC) Health Education Scale, and verify its reliability and validity. Methods The Elderly FC Health Education Scale was prepared by qualitative interviews, literature review, and Delphi method. The elderly patients who were over 60 years old and at Chinese PLA 181st Hospital were recruited by the purposive sampling method from January 2013 to August 2015.The diagnostic criteria of RomanⅢwas used to diagnose FC, the data of preliminary investigation and large sample test was used to form the formal scale, and its reliability and validity were further verified. Results The Elderly FC Health Education Scale was compiled with 6 dimensions and 28 items, and the Cronbach alpha coefficient which was the internal consistency reliability of the 6 factor was 0.965; the correlation coefficient analysis of equality reliability Kendall tau-b rank and various index variables score were positive correlation significantly. Both item level content validity index and scale level content validity index of the content validity were as a result of 1. The structure validity of the cumulated variance contribution ratio of the 6 factors were 60.15%. All factor loading coefficients between the items were more than 0.5, which indicated the fitting was good. Conclusions The reliability and validity of the Elderly FC Health Education Scale are good, and the scale may be used as a tool to prevent the elderly FC health education, and also be applied to the elderly FC patients in self-management and continue nursing after leaving hospital.
