RESUMO
Objective:To examine the reliability and validity of tolerance of mental pain scale (TMPS-10) in college students.Methods:A total of 2 171 college students were recruited in this study from November to December 2021.Sample 1( n=1 085) was tested for item analysis and exploratory factor analysis from November to December 2021.Sample 2 ( n=1 086) was tested for confirmatory factor analysis, convergence validity, and criterion validity analysis.Ninety-nine cases were randomly selected from sample 2 for retest intraclass correlation efficient (ICC) 30 days later.The questionnaire of suicide attitude (QSA), Beck depression inventory version 2 (BDI-Ⅱ), self-rating anxiety scale (SAS), and Chinese perceived stress scale (CPSS) were used to examine criterion validity of TMPS-10.The SPSS 25.0 and AMOS 21.0 softwares were used for statistical analysis. Results:The exploratory factor analysis extracted two common factors, which explained 72.33% of the total variance contribution rate.The confirmatory factor analysis showed a good model fit ( χ2/ df=7.85, AGFI=0.92, GFI=0.95, TLI=0.96, CFI=0.97, IFI=0.97, RMSEA=0.08). The combined reliability (CR) of the Chinese version of TMPS-10 and its two factors were 0.96, 0.93 and 0.89, and the average variances extracted (AVE) were 0.72, 0.73 and 0.63.The total score of TMPS-10 was positively correlated with the two dimensions of QSA (knowledge of the nature of suicide behavior and attitude to euthanasia) ( r=0.40, 0.09, both P<0.01), while was negatively correlated with the other two dimensions of QSA (attitude to suicide and attitude to suicide family members), and the total scores of BDI-Ⅱ, SAS, and CPSS ( r=-0.30, -0.34, -0.30, -0.45, -0.46, all P<0.01). The Cronbach α coefficients of the Chinese version of TMPS-10 and its two factors were 0.82, 0.89 and 0.93, and the spilt-half reliabilities were 0.85, 0.89 and 0.89.The ICC of the Chinese version of TMPS-10 and its two factors after 30 days were 0.77, 0.87 and 0.86. Conclusion:The Chinese version of TMPS-10 has good reliability and validity among college students, and it can effectively evaluate students' endurance of psychological pain.
