Time perspective is a phenomenon that could be differently conceptualized (e.g. as an attitude, as a flexible dynamic process, etc.) thus one of the ways to conceptualize time perspective is to consider it as a stable personality disposition. This chapter covers research studies that show a strong relationship between personality traits and time perspective. Particularly strong relations are found between future and conscientiousness, as well as past negative and neuroticism. What is more, there is sufficient evidence speaking in favour of time perspective being an independent construct that has additional prognostic value even after personality traits have been controlled for. This chapter also analyses the hypothesis that time perspective has likeliness to personality trait – is stable, broad and therefore can be considered as relatively stable dispositional characteristic.
