Psychometric properties of the 9-item version of the Temporal Satisfaction With Life Scale (TSWLS) in the Italian context

The aim of this paper was to validate and examine the psychometric properties of the 9-item Temporal Satisfaction With Life Scale (TSWLS) in the Italian context. Four studies were conducted. In Study 1, we performed an exploratory factor analysis. The 3-factor structure — past life satisfaction, present life satisfaction, and future life satisfaction — was confirmed. In Study 2 we tested the structure of the nine items of the scale, based on confirmatory factor analysis. The 3-factor structure with a high-order factor was the best factorial solution. In Study 3 we tested the concurrent validity of the TSWLS. The scale was significantly and positively related with life satisfaction, flourishing, and positive affects, and negatively related with negative affects. In Study 4 we showed the stability of the TSWLS using the test-retest method after an interval of four weeks.
