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. Recently, an English-language version of the Trier Inventory for Chronic Stress (TICS-EN) consisting of 57 items according to a systemic-requirement-resource model of health in nine subdomains of the chronic stress experience has been introduced.
Methods:
We constructed a new 9-item short version of the TICS 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.
