Primary use / Purpose: 

The Impersonal Trust Scale (ITS) is a 31-item inventory rated on a 5 point Likert-type scale. The scale’s purpose is to measure the degree of impersonal trust which exists within orginisations.


Within large organizations trust is becoming both more valuable and more impossible to achieve. The traditional, interpersonal form of trust which previously existed within organisations has been replaced by a new more impersonal one. The Impersonal Trust Scale (ITS) aims to measure this newer more impersonal form of organizational trust. The ITS measures impersonal trust through two sub-categories: capability, and fairness, each measured with 13 and 18 items, respectively.


The psychometric properties of the ITS are discussed in Vanhala, Puumalainen & Blomqvist (2011).
