Objective To develop the scale to measure online intimate relationship and test its validity and reliability for college students. Methods A total of 1 105 subjects were recruited in this investigation for 6 times.Based on literatures, open-ended questionnaire investigations, semi-structured interview and experts’ opinions, item analyses, exploratory factor analyses, validity and reliability analysis were conducted to develop the scale. Results The self-made scale showed a second-order structure, including intimacy, passion and commitment dimension.Confirmatory factor analysis showed that the model had good fit (χ2/df=3.47, GFI=0.92, NFI=0.90, CFI=0.92, TLI=0.90, IFI=0.92, RMSEA=0.08). The 3 dimensions had good internal reliability with Cronbach’s α coefficients from 0.73 to 0.89 and retest reliability coefficients from 0.80 to 0.91.In addition, the scale had good external validity and convergent validity. Conclusion The self-made scale has acceptable reliabilities and validities, which can be used to measure online intimate relationship for college students.
