Objective To analyze the use of outcome indicators and evaluation tools in randomized controlled trial(RCT)of music interventions for lung cancer-related anxiety and depression.Methods Nine databases were searched,and the literature was screened according to inclusion and exclusion criteria,followed by a summary of outcome indicators,and statistical analysis of classification and frequency of use according to the attributes of the outcome indicators.Results A total of 243 articles were retrieved,and 18 RCTs were finally included.The outcome indicators were classified into 8 indicator categories according to their functional attributes:anxiety scale(24.19%),depression scale(16.13%),quality of life scale(14.52%),sleep quality scale(9.68%),pain scale(4.84%),blood biochemical indicators(14.52%),vital signs(11.29%),and pulmonary and exercise function indicators(FEV1%,6MWD,BODE index)(4.84%).The problems are as follows:First,the overall risk of bias is high in the included RCTs.Second,the timing of measurement is variable due to inconsistency in the length of treatment.Third,the forms of music intervention are diverse.Besides,the use of other rating scales and objective indicators is low and safety indicators were neglected.Finally,the method of evaluation tools was single and some RCTs did not specify grading criteria.Conclusion The use of outcome indicators and evaluation tools in music interventions for lung cancer-related anxiety and depression has certain shortcomings,which affects the credibility of the trials.It is recommended to standardize the use of outcome indicators and establish a core set of indicators for clinical studies of music intervention for lung cancer-related anxiety and depression.
