This article introduces The Temporal Satisfaction With Life Scale (TSW
LS), and reports data establishing its reliability and validity as a m
easure of life satisfaction. The addition of a temporal dimension allo
ws the TSWLS to assess an individual's past, present, and future life
satisfaction. Data relevant to reliability and validity of the TSWLS w
ere gathered from three samples, including one college sample and two
adult samples. Moderate to strong correlations with other self- and pe
er-reported measures of well-being and life satisfaction were observed
. Factor analyses revealed a three-factor structure, with the factors
corresponding to past, present, and future lime frames. Measures of in
ternal and temporal reliability show the TSWLS to be a highly consiste
nt measure of global life satisfaction.
