Abstract:
Objective:To develop a scale to measure the sense of gain of the elderly, and to evaluate its reliability and validity.Methods:According to the content of the sense of gain, combined with the literature research method and interview method, the scale entry pool was established.After the expert consistency evaluation and the optimal test assembly method (OTA) analysis, the formal version of the scale was formed.The stratified sampling method was used to select 1 043 community-dwelling elders for the survey, and the reliability and validity of the scale were evaluated by methods based on classical test theory.Results:The scale of elderly sense of gain, which was screened by OTA method, included four dimensions: health status, relationship and communication, social security, and ideal expectation, with a total of 17 items. The Cronbach's α value of the formal version of the scale was 0. 850, and the Cronbach's α coefficients of the four dimensions were 0.721, 0.772, 0.779, and 0.930, respectively. The CR values of the combined reliabilities of each dimension were all above 0.7. In terms of AVE values, except for the health status dimension was acceptable, the other three dimensions were all above 0.36. The correlation coefficient between the sense of health acquisition and life satisfaction of the elderly was 0.531 ( P<0.01). Conclusion:The developed scale for measuring the sense of gain of the elderly has good reliability and validity, which can be used as an effective tool for measuring the sense of gain of the elderly.
