A Time to Sleep Well and Be Contented: Time Perspective, Sleep Quality, and Life Satisfaction

Area of Science:

• Psychology
• Sleep Science
• Well-being Research

Background:

• Time perspective, defined as habitual ways of relating to past, present, and future, is a key aspect of individual psychology.
• Poor sleep quality is a prevalent issue impacting overall health and life satisfaction.
• Understanding the interplay between temporal biases and sleep is crucial for mental health interventions.

Purpose of the Study:

• To investigate the relationship between time perspective and sleep quality in young adults.
• To test a mediation model where poor sleep quality links deviation from balanced time perspective (DBTP) to life satisfaction.
• To identify specific temporal biases that predict sleep quality.

Main Methods:

• A sample of 386 young adults completed the Zimbardo Time Perspective Inventory (S-ZTPI), Pittsburg Sleep Quality Index (PSQI), and Satisfaction with Life Scale (SWLS).
• Chronotype was measured as a control variable.
• Bivariate and regression analyses were used to examine associations and mediation.

Main Results:

• Deviation from balanced time perspective (DBTP) was the strongest predictor of poorer sleep quality.
• Time perspective accounted for approximately 20% of the variance in sleep quality, independent of chronotype.
• Poor sleep quality partially mediated the negative relationship between DBTP and life satisfaction.

Conclusions:

• Time perspective significantly influences sleep quality, with temporal biases negatively impacting sleep.
• Interventions aimed at balancing time perspective may improve sleep quality and enhance life satisfaction.
• The findings highlight a substantial link between time perspective, sleep problems, and reduced life satisfaction.
