Objective To develop QQ zone Self-disclosure Questionnaire to measure the level of college students′self-disclosure and test its reliability and validity.Methods By literature reference

in-depth exploration within research group

qualitative interview and expert verification the QQ zone Self-disclosure Questionnaire was developed and a total of 202 college students were surveyed.And the data was processed by item analysis

exploratory analysis

verification and reliability analysis.Results There were 3factors of open content

experience sharing and emotion demonstration

including 14 items.The data was verified through suitability test and Bartlett test of Sphericity and the result showed that the data was suitable for factor analysis（KMO=0.76
