Background: Although a variety of instruments are available that capture stress experience, the assessment of chronic stress has been hindered by the lack of economical screening instruments.

... covering all nine subdomains and evaluated it in two samples (total N=685). We then used confirmatory factor analysis to check factorial validity.Results: This version showed a highly satisfactory model fit, was invariant across participant gender, demonstrated a very high correlation with the original TICS (r=.94), and showed a moderate correlation (r=.58) with a measure of perceived stress in the past month.Conclusions: Therefore, this theoretically driven instrument can be recommended as a short version of the TICS in English language.
