Why we imagine our future: Introducing the Functions of Future Thinking Scale (FoFTS)

Imagining future events is a crucial cognitive process in adaptation, but impairments have been identified in a range of mental disorders. Taking a functional approach to future thinking, this paper reports on the development and deployment of a scale to assess the frequency of self-reported functions of future thinking: The Functions of Future Thinking Scale (FoFTS). In Study 1 (N = 565) items were developed and subjected to exploratory factor analysis. Ten factors were extracted representing distinct purposes of future thinking: Boredom Reduction, Death Preparation, Identity Contrasting, Negative Emotion Regulation, Social Bonding, Goal Setting, Planning, Problem-Solving, Decision-Making, and Positive Emotion Regulation. Construct, convergent and divergent validity were established. The FoFTS predicted unique variance in transdiagnostic variables even after accounting for frequency, attitudes, and clarity of future thought. In Study 2 (N = 467), confirmatory factor analysis showed the 10-factor FoFTS model was an excellent fit to the data. In Study 3 (N = 106) it was shown that participants with probable major depression, relative to non-depressed participants, reported a significantly different profile of future thinking for different purposes. In conclusion, the FoFTS can be used to examine future thinking from a functional perspective and may help enrich models of psychopathology.
