Development Of Self-care Ability Scale For Primary Care Of Breast Cancer Of Female Of Childbearing Age

Objective:The purpose of this paper is establishment Self-care ability scale for primary prevention of breast cancer in women of childbearing age and test its reliability and validity,to provide a reliable tool for evaluating the self-care ability of primary prevention of breast cancer in women of childbearing age.In order to help women of childbearing age find the self-care defects of primary prevention of breast cancer,meet the needs of self-care,improve the ability of self-care,and then reduce the risk of breast cancer,and provide a basis for targeted health education for medical staff.Methods:1.Literature review analysis:Based on Orem’s self-care theory and consulting relevant literature,to understand the research status of primary prevention assessment tools for breast cancer and its related risk factors at home and abroad.2.Semi-structured interview method:By using the method of objective sampling,20 women of childbearing age were selected for face-to-face semi-structured interviews,and combined with the results of literature analysis,the item pool of the scale of primary prevention self-care ability of breast cancer for women of childbearing age was constructed.3.Delphi expert interview method:According to the inclusion criteria of experts,23 experts were selected for two rounds of expert consultation,and after each round of consultation,the expert opinions were sorted out and analyzed,combined with item importance assignment,coefficient of variation and other screening items.to form the initial scale of primary prevention and self-care ability of breast cancer for women of childbearing age.4.The pre-experiment method:A pre-survey was conducted on 30 women of childbearing age who met the inclusion criteria,and the number of questions and the expression of items of the scale were evaluated,according to their opinions and survey results,the initial scale of primary prevention self-care ability of breast cancer for women of childbearing age was further revised and improved.5.Questionnaire survey method: A questionnaire survey was conducted among 336 women of childbearing age who met the inclusion criteria by convenience sampling,and the final items were determined by item analysis(extreme group comparison,correlation coefficient,homogeneity test,etc.).The formal scale of primary prevention self-care ability of breast cancer for women of childbearing age was formed through reliability and validity tests(internal consistency reliability,split-half reliability,test-retest reliability,content validity,construct validity,etc.).Results:1.Delphi’s result: Through literature analysis and qualitative interviews,the entry pool of the scale of primary prevention and self-care ability of breast cancer for women of childbearing age was preliminarily formed.Then 23 experts were selected for two rounds of Delphi expert consultation.The number of questionnaires distributed by the two rounds of expert consultation was 23 and 20 respectively,with a recovery rate of100%;The number of experts who put forward opinions was 15(65.22%)and 5(25%)respectively;The authority coefficients of the two rounds of expert consultation are0.84,0.85 respectively,and the coordination coefficients are 0.250、0.389 respectively.Finally,the initial scale of breast cancer primary prevention self-care ability scale for women of childbearing age with 4 dimensions and 32 items was formed.2.Project analysis results: The results of extreme group comparison method showed that t = 6.395-15.136(all P < 0.010),indicating that there was a good degree of distinction among the items.The correlation coefficient between each item and the total scale was 0.402-0.695(P < 0.010),and the Cronbach’s α coefficient of this scale was0.917.3.Reliability and validity of the scale: The Cronbach’s α coefficient of the scale is0.917,the half-and-half reliability is 0.948,the test-retest reliability is 0.998,the content validity index is 0.953,and the correlation validity is 0.881.Four common factors were extracted by exploratory factor analysis,and the contribution rate of cumulative variance was 65.115%.The results of confirmatory factor analysis(χ2 = 158.116,GFI=0.802,ICF=0.903,NFI= 0.850,IFI=0.904)showed that the scale had good reliability and validity.Conclusion:Based on Orem’s self-care theory and strictly following the principle and process of the scale,this study constructed a scale of primary prevention self-care ability of breast cancer for women of childbearing age,including 4 first-level items and 32 second-level items,with good reliability and validity,which can be used to evaluate the self-care ability of primary prevention of breast cancer in women of childbearing age,and provides a theoretical and practical basis for health education on primary prevention of breast cancer in women of childbearing age.It is of reference significance for the study of primary prevention of breast cancer in the future.
