Abstract

A total of 1,064 schoolchildren and university students were examined for associations between social jetlag and time perspective.

Chronotype is identified as a moderate predictor of future time perspective.
Sleep quality is a moderate predictor of negative past time perspective, fatalistic present time perspective, and deviation from balanced time perspective.
Mood seasonality moderately predicts present hedonistic time perspective.
Social jetlag shows a weak predictive association with present fatalistic time perspective, future time perspective, and deviation from balanced time perspective.
The findings suggest a weak but significant connection between social jetlag and time perspective in adolescents and young adults.

The phase of entrainment (chronotype) is known to be associated with time perspective (TP), suggesting that the state of circadian system is involved in the long-term planning of human life. However, little is known regarding the influence of circadian misalignment on long-term planning ability. The aim of this study was to investigate the association between social jetlag (SJL) and TP. A total of 1064 schoolchildren and university students (mean age ± standard deviation, 19.2 ± 2.9 years; range, 15-25 years; females, 71.7%) from four cities in the Russian Federation located between 56.9 and 61.7 degrees North completed the Munich ChronoType Questionnaire, the Pittsburgh Sleep Quality Index, the Seasonal Pattern Assessment Questionnaire, and Zimbardo Time Perspective Inventory. Study participants also indicated personal data (age, sex, height weight, place of residence, and achievements). A multiple regression analysis with stepwise inclusion of predictors in the model was performed to evaluate associations between time perspective characteristics (dependent variables) and predictor variables. The change inwas used as the measure of effect size. Chronotype was found to be a moderate predictor of future TP (= 0.034; Δ = 0.037). In addition, sleep quality was found to be a moderate predictor of past negative (= 0.043; Δ = 0.074), present fatalistic (= 0.021; Δ = 0.035), and deviation from balanced TP (= 0.034; Δ = 0.066). Mood seasonality was a moderate predictor of present hedonistic TP (= 0.016; Δ = 0.038), and social jetlag was a weak predictor of present fatalistic (= 0.052; Δ = 0.019), future (= -0.033; Δ = 0.004), and deviation from balanced TP (= 0.047; Δ = 0.012). In conclusion, this study found a weak but significant association between social jetlag and TP in adolescents and young adults. R B R B R B R B R B R B R B R B R2 2 2 2 2 2 2 2 2
