About this scale

A 56-item measure of five time perspectives: past-positive, past-negative, present-hedonistic, present-fatalistic, and future. Predicts goal-pursuit, well-being, and risk behaviour.

Sample item(s)

“I get nostalgic about my childhood (past-positive)”
“Painful past experiences keep being replayed in my mind (past-negative)”
“I do things impulsively (present-hedonistic)”
“Fate determines much in my life (present-fatalistic)”
“I am able to resist temptations when I know that there is work to be done (future)”

Reliability

Reported internal consistency: alphas 0.74–0.82 across 5 factors. As a rule of thumb, Cronbach’s α ≥ .70 is considered acceptable, ≥ .80 good, and ≥ .90 excellent for established measures.
