Performance contagion is an environmental influential factor that leads to change in the performance of a person who is susceptible to contagion. For the purpose of constructing a conceptual model of employees’ susceptibility to job performance contagion, a general scale for testing the amount of the individual’s susceptibility to performance contagion was developed in the present study. This scale was used in developing a questionnaire. Then the questionnaire was distributed to the 187 non-teaching staff of the Science and Research branch of Islamic Azad University and its validity, reliability, constructrelated evidence and contentrelated evidence were studied.
