The present study aimed to test the incremental validity of Time Perspective (TP) scales in predicting satisfaction with life and mood, over and above the Big Five personality traits. It also investigated whether the new TP construct of Future Negative perspective contributed to prediction of these outcomes. Participants (N = 265) completed four measures: Satisfaction With Life Scale (SWLS), UWIST Mood Adjective Checklist (UMACL), a modified Zimbardo Time Perspective Inventory (ZTPI), and NEO-Five Factor Inventory (NEO-FFI). Results confirmed the incremental validity of TP, although Big Five dimensions were independently predictive of life satisfaction and certain mood scales. Past Negative TP was the strongest single predictor of life satisfaction. However, Future Negative TP was be the strongest mood predictor from the TP universe, after controlling for the Big Five and remaining TP dimensions. Findings suggest that TP is an important aspect of personality for understanding individual differences in well-being.

The present study explores the relationship between Morningness–Eveningness and five personality dimensions for Time Perspective (TP), representing psychological attitudes toward time. Although these constructs are related to different time horizons (i.e., daytime vs. life-time horizon), existing empirical data regarding their personality and behavioral correlates allows for the prediction that some of the TP dimensions are significantly related to diurnal preference. A sample of 309 university students (30.1% male) aged between 19 and 26 completed the Polish adaptation of the morningness–eveningness questionnaire (MEQ) and the Zimbardo Time Perspective Inventory (ZTPI). Our research confirmed the main hypotheses, that Morningness is positively related to Future TP, whereas Eveningness correlates positively with Present-Hedonistic TP. Moreover, chronotype proved to be significantly related to other TP scales, as well as to the Deviation from Balanced Time Perspective (DBTP) coefficient, an indicator of a balanced time perspective, showing that Morning-types generally tend to express a more adaptive attitude toward psychological time. The possible mechanisms of the relationship, as well as implications for practice and theory are discussed in respect to the obtained data. The paper contributes to the knowledge about the relationship between circadian typology and personality in young adults.

Balanced time perspective (BTP) describes a tendency to focus on past, present and future time horizons that fosters well-being and positive life outcomes. Deviation from the balanced time perspective is a widespread method to measure the balance, but it makes assumptions regarding levels of time perspectives constituting BTP. In the present research we aimed to test the assumptions regarding levels of time perspectives constituting BTP by testing associations between time perspectives and domains of well-being in four independent samples (N = 1150). The results showed that higher well-being was fostered by greater past positive (PP) and future (F) and lower past negative (PN) and present fatalistic (PF) time perspectives in a linear manner. As for the present hedonistic (PH) perspective, the results were inconsistent indicating that this time orientation can be unrelated to well-being or related in an inverse U-shape manner. In the light of our results the optimal values for the deviation from the balanced time perspective, as measured with the Zimbardo Time Perspective Inventory, should be revisited and changed into PN 1, PP 5, PF 1, PH 3.4, F 5, with careful consideration whether or not to incorporate PH into the formula for the deviation from the balanced time perspective at all. We also showed that the deviation from the balanced time perspective using the above values better predicts well-being than the one using previously assumed levels.
