Abstract: Background　With the extensive improvement of people's education，domestic cold violence has also increased.Domestic cold violence has severe harm.It not only destroys the mental and psychological health，but also jeopardize the harmony of marriage lives.Meanwhile，it affects the social solidarity.However，there is no effective tools at this moment in China to measure the domestic cold violence.Objective　To develop and psychometrically evaluate a domestic cold violence scale，so as to assess household cold violence.Methods　According to practical definition of domestic cold violence，the initial items pool（20 items）of the scale were compiled by literature review in October 2015.After discussion by expert committee，the pilot test version of the scale remaining 10 items was developed，which was tested among 20 wives of gay men or bisexual men（known as Tongqi in Chinese for short）who were recruited through the online chatting platform “Lang man zhuan shen tongqi group” in December 2015（with a 100.0% response rate）as pre-investigation.All participants filled out the scale within 2 minutes and expressed that the scale was easy to understand.Then a large-scale test was conducted among 195 Tongqis who met inclusion criteria and were recruited from Internet by Respondent-driven sampling（RDS）method with 15 “seed participants” from February 2016 to March 2017.The Demographic Questionnaire，the testing version of the scale（10 items）and subscale of the Revised Conflict Tactics Scales（CTS-2S）were used to collect data.Four weeks later，20 participants were selected to fill out the questionnaire again by simple random sampling method.Correlation coefficient and extreme group method were performed for item analysis，and then valid questionnaires were randomly divided into two groups.One group was tested by Exploratory Factor Analysis（EFA）in order to evaluate the sub-factors of domestic cold violence scale，and the other group was tested by Confirmatory Factor Analysis（CFA）in order to evaluate the structural validity.The validity of the scale was evaluated by the correlation coefficient of scores of the subscale for the abused and the total score of CTS-2S，and the content validity was calculated by using the scores given by experts.Reliability of this scale was evaluated by homogeneity test，split-half reliability and retest reliability.Results　A total of 178 questionnaires（195 in all）in large-scale investigation were valid，with effective recovery rate of 91.3%.A total of 20 questionnaires were sent out in the second survey，and 15 valid questionnaires were collected，with an effective recovery rate of 75.0%.The correlation coefficient between the item and total score of the testing version scale were 0.515 to 0.793（P<0.05）．Scores of all items in high-score group（n=52）were higher than those in low-score group（n=50）（P<0.05）．The KMO of the testing version scale was 0.854，and Bartlett's test showed that χ2=390.689，P<0.001，indicating that CFA could be performed.Two common factors were extracted according to the principle of Eigen value >1.000 and explained 59.913% of the total variance.However，the load values of three items in the common factor 1 were all lower than 0.400，so they were deleted and the CFA was conducted again limited to extract only one common factor.At this point，54.342% of the cumulative variance was explained，and all the item load values were more than 0.400.The result of CFA showed that the fit index χ2/df，RMSEA，GFI，CFI，NFI，IFI，TLI were 1.726，0.091，0.932，0.950，0.892，0.951，0.925，respectively.The score of the subscale of the CTS-2S was positively related with the total score of the domestic cold violence scale（r= 0.431，P<0.001）．The CVI of this scale was 0.97.The Cronbach's α coefficient，split-half reliability and retest reliability of this scale were 0.848，0.820 and 0.714，respectively.Conclusion　The final version of domestic cold violence scale consists of 7 items.This study shows that the reliability and validity of the domestic cold violence scale is acceptable.Therefore，this scale can be considered to assess the situation of individuals who suffer from cold violence in marriage.
