| Objective:1.To Chineseize and revise the simplified version of Breast Cancer Treatment Outcome Scale(BCTOS-12)and examine its reliability and validity in the breast-conserving treatment patient population in China.2.To apply the Chinese version of the scale to investigate the current status of postoperative treatment outcomes reported by breast-conserving patients and to analyze the influencing factors.Methods:1.Chinese version of the scale and reliability testing: The simplified version of the Breast Cancer Treatment Outcome Scale(BCTOS-12)was selected through literature review and screening,and after obtaining the consent and authorization from the authors of the source scale,the first draft of the simplified Chinese version of the Breast Cancer Treatment Outcome Scale was formed through forward translation,back translation,group discussion,and Delphi expert consultation in accordance with the modified Brislin translation model.A total of 170 patients with breast-conserving treatment in a tertiary care hospital in Hunan Province were selected for formal survey using the convenience sampling method,and the validity of the scale was tested by content validity,structural validity,and validity of association with validity criteria;the reliability of the scale was tested by internal consistency reliability and retest reliability;the critical ratio method(CR value)and correlation coefficient method were used for item analysis of the scale.2.Current status survey: Using the convenience sampling method,207 cases of breast cancer breast-conserving treatment patients in a tertiary care hospital in Hunan Province were selected to fill in the general information questionnaire,the Chinese version of the Simplified Breast Cancer Treatment Outcome Scale,the Fear of Progression Questionnaire-Short Form(Fo P-Q-SF)and Functional assessment of cancer therapy-breast(FACT-B)were used to investigate the current status of breast cancer patients’ treatment outcomes and analyze the factors affecting them.The IBM SPSS Statistics 25.0 software was used to analyze the data statistically,and Spearman correlation analysis was used for correlation analysis;one-way ANOVA was used to compare the differences in scores of patients with different characteristics;multiple linear regression was used to analyze the influencing factors.Results:1.Localization and reliability and validity test of the scale: After two rounds of 15 expert letters and pre-investigations,a Chinese simplified version of the breast cancer treatment outcome scale with 2 dimensions and 15 items was preliminarily formed.The KMO test value was 0.922>0.8,and the Bartlett’s spherical test value was 2=1443.218,the degree of freedom was 105,and the difference was statistically significant(P<0.001).A total of 2 common factors were extracted from exploratory factor analysis,and the cumulative contribution rate was 56.369%.The correlation coefficient between each item of the scale and the total score of the scale was0.438～0.830,the correlation coefficient reached significance >0.4(P<0.01),the critical ratio CR of 15 items was between 5.955～35.000,the CR value was >3,and the difference was statistically significant(P<0.01).The Chinese version of the scale Cronbach’s α coefficient is 0.898,the aesthetic morphological dimension Cronbach’s α coefficient is 0.754,the functional state dimension Cronbach’s α coefficient is 0.951,and the retest reliability is 0.976～0.979.The content validity S-CVI is 0.955,and the I-CVI is 0.833～1.00.he Spearman correlation analysis results showed a general consistency(r=0.334,P<0.05)between aesthetic appearance outcomes and breast symptoms,and a moderate consistency(r=0.571,P<0.05)with arm symptoms;The functional status outcome showed moderate consistency with breast symptoms(r=0.440,P<0.05),and high consistency with arm symptoms(r=0.658,P<0.05),and the validity of the correlation was good.2.Status survey result: A total of 207 valid questionnaires were collected in this study,and the score data of each dimension of the Chinese simplified breast cancer treatment outcome scale showed a non-normal distribution after normality test.The functional state and aesthetic form dimensions were 1.29(1.14,1.71)and 1.25(1.25,1.63),respectively.Spearman correlation analysis found that functional status outcomes were positively correlated with phobic disease progression scores and negatively correlated with quality of life scores(P<0.001).The results of univariate analysis showed that age,disease course,and adjuvant therapy(P<0.05)in general demographic data were the influencing factors of postoperative functional status outcomes in patients with BCS.The results of multiple linear regression analysis showed that age,disease course,adjuvant treatment,and per capita monthly household income were the influencing factors of postoperative functional status outcomes in BCS patients,which could explain 20.5%of the variation in functional status outcomes.Conclusions:1.This study followed the scale introduction method and the improved Brislin translation model,and preliminarily completed the cross-cultural debugging of the simplified breast cancer treatment outcome scale,which was tested by psychological measurement methods and showed that the Chinese version of the scale had good reliability and validity,and could be used to evaluate the functional status and aesthetic morphological outcomes of patients after breast conserving surgery based on the patient’s perspective.2.The quality of life of BCS patients was at a high level,and the score of phobic disease progression was low,and correlation analysis showed that the postoperative functional status and aesthetic morphological outcomes reported by patients were positively correlated with quality of life and negatively correlated with phobic disease progression.Analysis of influencing factors showed that age,monthly household income,adjuvant treatment,and disease duration all influenced the self-reporting of functional status outcomes in BCS patients. |
