Time Perspective

"Time perspective is a multidimensional, individual-varying, and age-related construct that is defined as thoughts and feelings about the past, present, and future" (Mello, 2017)


The Adolescent and Adult Time Inventory (AATI; Mello & Worrell, 2007) assesses multiple dimensions of time perspective, including, time orientation, time relation, time attitudes, time meaning, and time frequency. The AATI has yielded reliable and valid scores in more than a dozen countries (Mello & Worrell, 2017). We invite interested scholars to use the AATI in their research. We permit use of the existing versions and would appreciate being informed of its application and results. Please contact either of us if you are interested in developing the AATI into additional languages. Zena R. Mello (zmello@sfsu.edu) and Frank C. Worrell (frankc@berkeley.edu)
